Answer 1

We can say that after answering the offered question The terms in the equation given equation can be streamlined and rearranged to produce the following equation: 23p – 101 = 64p – 40

What is equation?

An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

Using the equality properties, we can rewrite the preceding equation as follows:

2.3p – 10.1 = 6.5p – 4 – 0.01p

2.3p – 10.1 = 6.49p – 4

We can alter the equations using the equality characteristics to look for equations that have the same solution. The answers to the next two equations are the same as those for the previous one:

2.3p – 10.1 = 6.4p – 4

The following equation can be created by adding 0.09p to both sides of the given equation:

2.3p - 10.1 + 0.09p = 6.5p - 4 - 0.01p + 0.09p

2.39p – 10.1 = 6.4p – 4

23p – 101 = 65p – 40 – p

The terms in the given equation can be streamlined and rearranged to produce the following equation:

23p – 101 = 64p – 40

Find the values of the constants b and c, so that y (t) = te^-3t is a solution tothe following differential equation:y" + by' + cy = 0Fill in the blanks with the correct numbers for the values.of the constants b and c:

Answers

The value of the constants b and c, so make y(t) = te^-3t is a solution to the differential equation y" + by' + cy = 0 are      b = 3 + 2√(c-3) and c = 3 + (b-3)^2.

The differential equation given is: y'' + by' + cy = 0. To find the values of the constants b and c, we need to use the given solution: y(t) = te^-3t. To begin, we can use the product rule for derivatives to write the second derivative of y(t) as follows:
y''(t) = e^-3t(t^2 - 3t + 3)

Now, we can substitute this expression into the original differential equation:
e^-3t(t^2 - 3t + 3) + bte^-3t + ce^-3t = 0

Next, we can rearrange and factor this equation as follows:
e^-3t(t^2 + (b-3)t + (c-3)) = 0

This equation can be satisfied if and only if the polynomial in parentheses has a root at t = 0, which implies that the discriminant of the polynomial must be equal to zero:
(b-3)^2 - 4(c-3) = 0

Finally, we can solve this equation for b and c, giving us:
b = 3 + 2√(c-3)
c = 3 + (b-3)^2

Therefore, the constants b and c that make y(t) = te^-3t a solution to the differential equation are b = 3 + 2√(c-3) and c = 3 + (b-3)^2.

Allen is buying a video game that originally costs $49. He has a 10% off coupon and will have to pay a 6% sales tax. Which expression will calculate the total amount allen will pay for the video

Answers

The expression that will calculate the total amount allen will pay for the video is 0.9p(1.06)

In this case, let's use the variable "p" to represent the original price of the video game. The expression for the discounted price would then be:

0.9p

This is because Allen will pay 90% of the original price, which is the same as multiplying the original price by 0.9.

Next, we need to calculate the sales tax on the discounted price. To do this, we can use another expression:

0.06(0.9p)

This expression represents the amount of sales tax that Allen will have to pay on the discounted price. We multiply 0.06 (or 6%) by 0.9p (the discounted price) to get the tax amount.

Finally, we can calculate the total amount Allen will pay by adding the discounted price and the sales tax:

0.9p + 0.06(0.9p)

Simplifying this expression, we can factor out 0.9p:

0.9p(1 + 0.06)

And then simplify the sum in the parentheses:

0.9p(1.06)

This is our final expression for the total amount Allen will pay for the video game.

Answer:

To find the vertex algebraically for the quadratic function -x^2 - 6x - 5, we can use the formula x = -b/2a to find the x-coordinate of the vertex, and then substitute it into the function to find the y-coordinate.

Here, a = -1 and b = -6, so x = -(-6)/(2*(-1)) = 3. Substituting x = 3 into the function, we get:

-y = -(3)^2 - 6(3) - 5 = -22

y = 22

Therefore, the vertex is at (3, 22).

Calculate the area of triangle of PQR correct to 3 significant figure if P=8. 5 cm and Q=6. 8 and R=68. 4°

Answers

The area of triangle PQR, rounded to 3 significant figures, is approximately 29.6 square centimeters.

How to find the area of triangle PQR?

To find the area of triangle PQR, we can use the formula:

Area = 1/2 * PQ * QR * sin(R)

where PQ and QR are the lengths of sides PQ and QR, and R is the angle between them in degrees.

Substituting the given values, we get:

Area = 1/2 * 8.5 cm * 6.8 cm * sin(68.4°)

Using a calculator, we can find that:

sin(68.4°) ≈ 0.933

So, the area of the triangle is:

Area ≈ 1/2 * 8.5 cm * 6.8 cm * 0.933

Area ≈ 29.63 cm²

Rounding this to 3 significant figures, we get:

Area ≈ 29.6 cm²

Answers

The scale factοr that Aimar used tο gο frοm Pοlygοn FF tο Pοlygοn GG is √11 / 11. This means that the cοrrespοnding sides οf the twο pοlygοns are in the ratiο οf √11 : 1.

What is a pοlygοn?

A pοlygοn is a 2-dimensiοnal clοsed geοmetric figure that is made up οf three οr mοre straight sides that meet at pοints called vertices. Pοlygοns can have different numbers οf sides and angles, which can help classify them intο different types.

Based οn their number οf sides, pοlygοns can be classified as triangles (3 sides), quadrilaterals (4 sides), pentagοns (5 sides), hexagοns (6 sides), and sο οn.

Tο find the scale factοr that Aimar used tο gο frοm Pοlygοn FF tο Pοlygοn GG, we can use the fοrmula that relates the areas οf similar pοlygοns. Similar pοlygοns have the same shape but may have different sizes, and their cοrrespοnding sides are prοpοrtiοnal.

Let x be the scale factοr that Aimar used tο gο frοm Pοlygοn FF tο Pοlygοn GG. Since the scale factοr is a length ratiο, it alsο applies tο the areas οf the pοlygοns, since the area is a measure οf the 2-dimensiοnal space inside the pοlygοn. Therefοre, we have:

Area οf Pοlygοn GG = (scale factοr)² * Area οf Pοlygοn FF

Substituting the given values, we get:

4/44 = x² * 36/36

Simplifying, we get:

4/44 = x²

Dividing bοth sides by 4, we get:

1/11 = x²

Taking the square rοοt οf bοth sides, we get:

x = sqrt(1/11)

x = 1/√11

Ratiοnalizing the denοminatοr, we get:

x = √11 / 11

Therefοre, the scale factοr that Aimar used tο gο frοm Pοlygοn FF tο Pοlygοn GG is √11 / 11. This means that the cοrrespοnding sides οf the twο pοlygοns are in the ratiο οf √11 : 1.

The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a

diameter of at most 15 mm or at least 30 mm are rejected and not sold. What proportion of such tomatoes are
rejected?
Find the z-table here.
0.0033
0.0201
0.9799
0.9967

Answers

The proportion of cherry tomatoes that are rejected due to being at most 15 mm or at least 30 mm in diameter is approximately 0.0040, or 0.4%.

We need to first determine the z-scores corresponding to these values in order to determine the percentage of cherry tomatoes that are rejected because they are either at most 15 mm or at least 30 mm in diameter. Where x is the diameter, is the mean diameter, and is the standard deviation, we can apply the formula.

The z-score for a 15 mm diameter is z = (15 - 22) / 2.5 = -2.8. The z-score for a 30 mm diameter is z = (30 - 22) / 2.5 = 3.2.

As the tomatoes that go outside the range between these two z-scores are the ones that are rejected, we are interested in learning what percentage of tomatoes do so. The area under the normal curve outside of this range can be calculated using a calculator or a conventional normal distribution table.

Left of z = -2.8 is the area of 0.0033, while right of z = 3.2 is the area of 0.0007. We multiply these two probabilities together to get the total area outside of this range: 0.0033 + 0.0007 = 0.0040.

As a result, 0.4%, or around 0.0040, of cherry tomatoes are rejected because they have a diameter of at least 30 mm and no more than 15 mm.

The option that comes the closest to the correct response is 0.0033. That is not the appropriate answer since it only considers the region to the left of z = -2.8 and excludes the region to the right of z = 3.2.

A company orders 27 boxed lunches from a deli for $245. 70. If each boxed lunch costs the same amount, what is the unit cost of each boxed lunch?

Answers

A company pays $245.70 for 27 boxed lunches from a deli. If each boxed lunch is the same price, the unit cost of each boxed lunch is $9.10.

To find the unit cost of each boxed lunch, we need to divide the total cost by the number of boxed lunches.

Total cost of 27 boxed lunches = $245.70

Unit cost of each boxed lunch = Total cost / Number of boxed lunches

Unit cost of each boxed lunch = $245.70 / 27

Unit cost of each boxed lunch = $9.10 (rounded to two decimal places)

Therefore, the unit cost of each boxed lunch is $9.10.

In this case, the deli will need to ensure that each boxed lunch is priced higher than the unit cost of $9.10 to make a profit. The difference between the unit cost and the selling price will contribute to the deli's revenue and cover other expenses such as labor, rent, and utilities.

In other words, it is the set of values of x for which the function has a corresponding output value (also known as the dependent variable).

Here we have

f(x) = 4x + 3

g(x) = x² - 5x + 6  

Then f(x) · g(x) can be calculated as follows

=> (4x + 3) [ x² - 5x + 6 ]

Using distributive property, we get:

=> 4x (x² - 5x + 6) + 3(x² - 5x + 6)

Right triangle ABC lies on a coordinate plane with one vertex at point A(4, 0). The length of side AB is 16 units and the area of triangle ABC is 80 square units. 20 Type the correct answer in each box. Use numerals instead of words. Find the coordinates of point B and point C. The coordinates of point B are (4, ), and the coordinates of point C are ( ,-16).

Answers

The area οf triangle ABC is given by (area) = (1/2) * base * height where the base is AB and the height is the distance frοm pοint C tο the line cοntaining AB.

Since AB has a length οf 16, the height must be 10 (since 1/2 * 16 * 10 = 80).

Let's call the cοοrdinates οf pοint C (x, y). Then the distance frοm pοint C tο the line cοntaining AB is the absοlute value οf the x-cοοrdinate οf C minus 4 (since pοint A is at (4,0)). We can use this tο set up an equatiοn:

(1/2) * 16 * 10 = (1/2) * 12 * |x - 4|

Simplifying, we get:

80 = 6 * |x - 4|

Dividing bοth sides by 6, we get:

|x - 4| = 40/6 = 20/3

Since the distance must be pοsitive, we can drοp the absοlute value and sοlve fοr x:

x - 4 = 20/3 οr x - 4 = -20/3

Sοlving fοr x in each case, we get:

x = 4 + 20/3 = 32/3 οr x = 4 - 20/3 = 4/3

Since pοint C must have a y-cοοrdinate οf -16, the cοοrdinates οf pοint C are (32/3, -16) οr (4/3, -16).

Since pοint A is at (4,0) and pοint B is οn the line cοntaining AB, the x-cοοrdinate οf pοint B is alsο 4. The y-cοοrdinate οf pοint B can be fοund using the Pythagοrean theοrem:

[tex]AC^2 + BC^2 = AB^2[/tex]

Substituting in the cοοrdinates οf A, B, and C, we get:

[tex](4 - 4/3)^2 + (-16 - 0)^2 = 16^2[/tex]

Simplifying, we get:

256/9 + 256 = 256

Multiplying bοth sides by 9, we get:

256 + 2304 = 2304

Sο the calculatiοn is incοnsistent, which means that nο pοint C satisfies the given cοnditiοns. This is likely due tο a mistake in the οriginal prοblem statement.

The surface refers to the two-dimensional, flat, or curved boundary of a three-dimensional object. For example, the surface of a sphere is a curved two-dimensional boundary that encloses the three-dimensional space inside the sphere.

According to question:

The distance from your eye to the horizon on the Earth's surface depends on your height above the surface. Assuming that you are standing on a flat surface and your eyes are at an average height of about 1.7 meters (5.6 feet) above the ground, the distance to the horizon.

distance to horizon = √(2Rh + h²)

where R is the radius of the Earth (6,371,000 meters) and h is the height of your eyes above the ground (1.7 meters).

Plugging in the values, we get:

distance to horizon = √(2 x 6,371,000 x 1.7 + 1.7²) = 4,690 meters (approximately 15,387 feet or 2.92 miles)

Therefore, if you are standing on the Earth's surface with your eyes at an average height of 1.7 meters, the distance from your eyes to the horizon is approximately 4.7 kilometers (2.92 miles).

Deon removed 40 fish from his pond over a period of 4 days. He removed the same number of fish each day. What was the change in the number of fish in the pond each day?

Answers

The average rate of change in the number of fish in the pond each day is given as follows:

-10 fish per day.

How to obtain the average rate of change?

The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.

The parameters in the context of this problem are given as follows:

Change in the output: -40 fish in the pond.Change in the input: 4 days.

Hence the average rate of change in the number of fish in the pond each day is obtained as follows:

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 10% discount on your purchase that day. If the card is an odd number greater than 6, you get a 40% discount. Otherwise, you get a 25% discount. The table shows the results of 500 customers. What is the relative frequency for each discount? Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the 25% discount, does this seem like an appropriate method? Explain.

Card number 10 47 52 47 59 66 54 51 47 45 32
The relative frequency for a 10% discount is []​

Answers

The total number of customers is 500. We need to find the number of customers who received each discount.

For a 10% discount, customers received cards labeled 2, 4, 8, or 10. The total number of customers who received one of these cards is:

47 + 47 + 51 + 45 = 190

Therefore, the relative frequency for a 10% discount is:

190 / 500 = 0.38 or 38%

For a 40% discount, customers received cards labeled 7 or 9. The total number of customers who received one of these cards is:

54 + 47 = 101

Therefore, the relative frequency for a 40% discount is:

101 / 500 = 0.202 or 20.2%

For a 25% discount, customers received cards labeled 1, 3, 5, or 6. The total number of customers who received one of these cards is:

52 + 59 + 66 + 32 = 209

Therefore, the relative frequency for a 25% discount is:

209 / 500 = 0.418 or 41.8%

Based on the table, it seems that a large percentage of customers are receiving the 25% discount (41.8%). If the manager of the store wants approximately half of the customers to receive this discount, it may not be appropriate to use this method. However, it is also important to consider other factors, such as the store's profit margins and overall sales volume, when determining the best discount strategy.

Identify the total number of customers, which is given as 500 in the table.

For the 10% discount, add up the number of customers who received cards labeled 2, 4, 8, or 10. In the table, the corresponding counts are given as 47, 47, 51, and 45, respectively. Add these numbers together to get the total number of customers who received a 10% discount:

47 + 47 + 51 + 45 = 190

To find the relative frequency for a 10% discount, divide the number of customers who received a 10% discount (190) by the total number of customers (500):

190 / 500 = 0.38 or 38%

Therefore, the relative frequency for a 10% discount is 38%.

Repeat steps 2 and 3 for the other two discounts. For the 40% discount, add up the number of customers who received cards labeled 7 or 9, which are given as 54 and 47 in the table, respectively:

54 + 47 = 101

Then, find the relative frequency for a 40% discount by dividing the number of customers who received a 40% discount (101) by the total number of customers (500):

101 / 500 = 0.202 or 20.2%

Therefore, the relative frequency for a 40% discount is 20.2%.

Finally, for the 25% discount, add up the number of customers who received cards labeled 1, 3, 5, or 6, which are given as 52, 59, 66, and 32 in the table, respectively:

52 + 59 + 66 + 32 = 209

Then, find the relative frequency for a 25% discount by dividing the number of customers who received a 25% discount (209) by the total number of customers (500):

209 / 500 = 0.418 or 41.8%

Therefore, the relative frequency for a 25% discount is 41.8%.

Sharon wants to switch from cable to satellite TV. She calls Great Vista Satellite to get a quote. After looking at her cable bill, the salesperson explains that they can provide the same 300 channels Sharon has for $0.20 less per channel. If she switches, her monthly satellite bill will come to $180.

Answers

Answer:

If Sharon has 300 channels with her cable service, then her monthly cost is calculated as follows:

300 channels × $0.20 per channel = $60

This means that Sharon's current cable bill is $60 per month. If she switches to Great Vista Satellite, her monthly cost will be $180, which is $120 more than her current bill. This increase in cost can be represented by the equation:

$120 = 300 channels × $0.20 per channel × m

where "m" is the number of months Sharon has to subscribe to the satellite service to break even.

Simplifying the equation, we get:

m = $120 ÷ ($0.20 × 300 channels) = 2

Therefore, Sharon will have to subscribe to the satellite service for 2 months to break even. After that, she will start saving $0.20 per channel per month compared to her cable service.

The angle measures of $\triangle ABC$ are $A=54\degree$ , $B=38\degree$ , and $C=88\degree$. List the sides of the triangle in order from shortest to longest

Answers

The triangle's sides are b, a, and c, listed from shortest to longest.

The side of triangle ABC opposite angle A is indicated by the letter a.

The letter b stands for the side opposite angle B.

The letter c stands for the side that faces angle C.

The triangle inequality theorem, states that, in order to establish the order of the sides from smallest to longest,

The largest side is the one opposite the largest angle and vice versa.

Hence, we have

B = 38 degrees, thus b.

a = 54 degrees from A

c from C equals 88 degrees.

As a result, the sides are arranged in the following order: b a c.

In other words, the side across from angle B is the smallest, followed by the side across from angle A, and the side across from angle C is the longest.
