Answer 1

Using the bearing and trigonometry in the problem, the distance of the waterfall from the lake is 7.94km

How far away is the waterfall from the lake?

To determine the distance between the waterfall and the lake, we can use trigonometry and the given information about the bearing and the distance in a south direction.

To find the distance between the waterfall and the lake, we can use the concept of right triangles and trigonometric functions.

Since the bearing is given as 236°, we can subtract this angle from 180° to find the angle formed by the south direction and the line connecting the lake and the waterfall:

180° - 236° = -56°

Now, we can consider the south direction as the reference direction (0°) and the line connecting the lake and the waterfall as the hypotenuse of a right triangle.

Using the cosine function, we can calculate the length of the side adjacent to the angle (-56°), which represents the distance between the waterfall and the lake:

cos θ = adjacent / hypothenuse

Adjacent = Hypotenuse * cosθ

Let's substitute the values into the formula:

Adjacent  = 14.2 km * cos(-56°)

To calculate the cosine of -56°, we can use the fact that the cosine function is an even function:

cos(-56°) = cos(56°)

Adjacent side = 14.2 cos(56)

Adjacent side = 7.94km

Answer 2

Answer:

The waterfall is approximately 8.91 km away from the lake

Step-by-step explanation:

To find the distance between the waterfall and the lake, we can use trigonometry and the given information about the bearing and the southward direction.

Since the waterfall is 14.2 km south of the lake, the line connecting the waterfall and the lake forms a right triangle with the south direction being the adjacent side, the distance between them being the hypotenuse, and the angle formed between them being the bearing of 236°.

To find the distance between the waterfall and the lake, we can use the cosine function, which relates the adjacent side, hypotenuse, and angle:

cos(236°) = adjacent side / hypotenuse

Let's denote the distance between the waterfall and the lake as "d." The adjacent side represents the southward direction.

cos(236°) = d / 14.2 km

Solving for "d":

d = cos(236°) * 14.2 km

Using a calculator:

d ≈ -8.91 km

Since distance cannot be negative, we take the absolute value:

|d| ≈ 8.91 km

Therefore, the waterfall is approximately 8.91 km away from the lake.

Question number 13 needs to answered

Answers

Final speed after slowing down by 15 miles per hour and reducing the speed by one third is 25 miles per hour.

Let's break down the steps to determine the final speed:

Step 1: Convert the speed from miles per minute to miles per hour.

Since you're driving one and a half miles per minute, we need to convert it to miles per hour. There are 60 minutes in an hour, so we multiply 1.5 by 60 to get 90 miles per hour.

Step 2: Slow down by 15 miles per hour.

Subtract 15 from the initial speed of 90 miles per hour, resulting in 75 miles per hour.

Step 3: Reduce the speed by one third.

To find one third of 75 miles per hour, we divide it by 3, which gives us 25 miles per hour.

Therefore, the final speed after slowing down by 15 miles per hour and reducing the speed by one third is 25 miles per hour.

A stainless steel patio heater is a square pyramid. the length of one of the base is 23.8. The slant height of the pyramid is 89.3 in. What is the height of the pyramid?

Answers

To find the height of the square pyramid, we can use the Pythagorean theorem. The slant height of the pyramid (s) is the hypotenuse of a right triangle formed by the height (h), half the length of the base (b/2), and the slant height.

Using the Pythagorean theorem:

s^2 = (b/2)^2 + h^2

We are given that the length of one of the base sides (b) is 23.8 and the slant height (s) is 89.3.

Plugging in the values:

89.3^2 = (23.8/2)^2 + h^2

Simplifying:

h^2 = 89.3^2 - (23.8/2)^2

h^2 = 7950.49 - 141.64

h^2 = 7808.85

Taking the square root of both sides:

h = √7808.85

h ≈ 88.37

Therefore, the height of the square pyramid is approximately 88.37 inches.[tex]\huge{\mathcal{\colorbox{black}{\textcolor{lime}{\textsf{I hope this helps !}}}}}[/tex]

Find the equation using the point slope formula or slope intercept formula for the two sets of points. (19,-16) (-7,-15)

Answers

The equation of the Line passing through the points (19, -16) and (-7, -15) is: y = (-1/26)x - 397/26

The equation of a line using the point-slope formula or the slope-intercept form, we need either the slope of the line or the y-intercept. Let's calculate the slope of the line using the given points (19, -16) and (-7, -15).

The slope (m) can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

Using the coordinates (19, -16) as (x1, y1) and (-7, -15) as (x2, y2), we can substitute these values into the slope formula:

m = (-15 - (-16)) / (-7 - 19)

m = (-15 + 16) / (-7 - 19)

m = 1 / (-26)

m = -1/26

Now that we have the slope of the line, we can use either the point-slope formula or the slope-intercept form to find the equation.

Using the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept, we can substitute the slope (-1/26) and one of the given points (19, -16) into the equation:

-16 = (-1/26) * 19 + b

To solve for b, we can simplify the equation:

-16 = -19/26 + b

To isolate b, we can add 19/26 to both sides of the equation:

-16 + 19/26 = b

Now, we can find the common denominator of 26 and add the fractions:

(-416 + 19) / 26 = b

-397/26 = b

Therefore, the equation of the line passing through the points (19, -16) and (-7, -15) is: y = (-1/26)x - 397/26

This equation represents the line with a slope of -1/26 and a y-intercept of -397/26.

If 5sinA=3 and cosA is smaller than 0 , with an aid of a diagram determine the value of 2tanAcosA

Answers

If 5sinA=3 and cosA is smaller than 0  , the value of 2tanAcosA is -6/5.

To determine the value of 2tanAcosA, we need to find the values of tanA and cosA first. We are given that 5sinA = 3 and cosA is smaller than 0.

Let's start by finding sinA. Since sinA = opposite/hypotenuse, we can set up a right triangle with the opposite side as 3 and the hypotenuse as 5. Using the Pythagorean theorem, we can find the adjacent side:

adjacent^2 = hypotenuse^2 - opposite^2

adjacent^2 = 5^2 - 3^2

adjacent^2 = 25 - 9

adjacent^2 = 16

adjacent = 4

Now we can find cosA using the adjacent side and hypotenuse:

cosA = adjacent/hypotenuse

cosA = 4/5

Since cosA is smaller than 0, it means that cosA is negative. Therefore, cosA = -4/5.

Next, we can find tanA using the given information. tanA = opposite/adjacent = 3/4.

Now, we can calculate the value of 2tanAcosA:

2tanAcosA = 2 * (3/4) * (-4/5) = -24/20 = -6/5

Therefore, the value of 2tanAcosA is -6/5.

To aid in visualizing the situation, it would be helpful to draw a right triangle with the appropriate side lengths based on the given values of sinA and cosA. The opposite side would be 3, the adjacent side would be 4, and the hypotenuse would be 5. Additionally, since cosA is negative, we can indicate the direction of the adjacent side to be in the negative x-axis direction. This diagram would provide a visual representation of the values and relationships involved in solving the problem.

Multiplying polynomials 4n2(n2 + 5n - 8)

Answers

Answer:

4n^4 + 20n^3 - 32n^2

Step-by-step explanation:

We have to distribute 4n2 to each term.

4n2 x n2. We can multiply the two n2 together resulting in 4n^4.

Now we do 4n2 x 5n. Here we multiply 4 x 5 which equals 20. Then, we multiply the n2 and n. Which results in n^3. Now we put them together; 20n^3.

Finally, we multiply 4n2 by -8. Since 8 doesn't have any variables, we just multiply the 4 and -8. Which equals to -32, now we just combine -32 and the variable; -32n2.

Now we combine these terms together. Our final answer is, 4n^4 + 20n^3 -32n^2.

Answers

Answer:

The theoretical probability of rolling a 5 or 6 can be calculated by finding the sum of the probabilities of rolling a 5 and rolling a 6. Since the number cube has 6 equally likely outcomes, the probability of rolling a 5 or 6 is:

Theoretical probability = (probability of rolling a 5) + (probability of rolling a 6)

= 1/6 + 1/6

= 2/6

= 1/3

The experimental probability of rolling a 5 or 6 can be calculated by dividing the number of times a 5 or 6 was rolled by the total number of rolls. From the given data, the number of rolls for each outcome is:

Outcome | Number of Rolls

1 | 81

2 | 95

3 | 79

4 | 89

5 | 80

6 | 76

Experimental probability = (number of times a 5 or 6 was rolled) / (total number of rolls)

= (number of times a 5 was rolled + number of times a 6 was rolled) / 500

= (80 + 76) / 500

= 156 / 500

= 0.312

Therefore, the theoretical probability of rolling a 5 or 6 is 1/3, and the experimental probability is approximately 0.312.

You randomly select a person from the United States. What is the probability that the person's triglyceride level is less than 80?

Answers

The probability that a aimlessly  named person's triglyceride  position is  lower than 80 milligrams per deciliter is  roughly0.0618 or6.18.    

 

To calculate the probability that a aimlessly  named person's triglyceride  position is  lower than 80 milligrams per deciliter, we can use the conception of standard normal distribution.  

First, we need to  regularize the value of 80 using the z- score formula  z = ( x- μ)/ σ  Where  x =  80( the value we want to calculate the probability for)  μ =  134( mean triglyceride  position)  σ =  35( standard  divagation)  Plugging in the values, we get  z = ( 80- 134)/ 35  z = -54/ 35  z ≈-1.543

Next, we need to find the corresponding area under the standard normal distribution  wind for a z- score of-1.543. We can use a standard normal distribution table or a calculator to find this area.

Looking up the z- score in the table or using a calculator, we find that the area to the left wing of z = -1.543 is  roughly0.0618.  

thus, the probability that a aimlessly  named person's triglyceride  position is  lower than 80 milligrams per deciliter is  roughly0.0618 or6.18.

5–√: This is an irrational number because it cannot be expressed as a fraction or a ratio of integers. The square root of 5 is not a perfect square, so it is irrational.

To convert the decimal 0.44444... to a fraction, we can set it as the variable x and solve the equation:

x = 0.44444...

Multiply both sides by 10 to move the decimal point:

10x = 4.44444...

10x - x = 4.44444... - 0.44444...

9x = 4

Divide both sides by 9:

x = 4/9

Therefore, the decimal 0.44444... is equivalent to the fraction 4/9.

Matching the numbers with their classifications:

0.3333...: This is a repeating decimal.

3.48372...: This is a nonrepeating decimal.

3.3: This is a terminating decimal.

The missing angles are m ∠1 = 53° and m ∠k = 12°.

Given that are two circles we need to find the missing measures,

Using the concept of intersecting chords angles,

When two chords intersect inside a circle, the angle between the chords is half the sum of the intercepted arcs.

And,

When two chords intersect outside a circle, the angle between the chords is half the difference of the intercepted arcs.

So,

a) m ∠1 = 1/2 [arc LP + arc RQ]

m ∠1 = 1/2 [50°+56°]

m ∠1 = 1/2 × 106°

m ∠1 = 53°

b) m ∠k = 1/2 [arc MJ - arc LR]

arc LR = 360° - [72° + 100° + 140°]

arc LR = 48°

So,

m ∠k = 1/2 [72° - 48°]

m ∠k = 12°

Hence the missing angles are m ∠1 = 53° and m ∠k = 12°.

We can see here that the measure that should be used to summarize the data is: A. Mean.

What is mean?

The mean, which is used to indicate the average value of a group of values in statistics, is a measure of central tendency. It is determined by adding up all of the dataset's values and then dividing the total by the number of values.

Mean = (Sum of all values) / (Total number of values)

The mean is widely used in statistics to summarize and describe the average value of a dataset. It is a useful measure for understanding the central tendency of a set of values.

The meaure of m∠KJL in the circle is:

m∠KJL = 25°

How to find the angle m∠KJL in the circle?

Since ΔJKL is inscribed in circle P with diameter JK and mJL = 130°. Thus, m∠JLK is an inscribed angle.

Since an angle inscribed in a semicircle is a right angle.

Thus, m∠DFE = 90°

Since the measure of inscribed angle is half the measure of its intercepted arc. Thus:

m∠JKL = 1/2 * mJL

m∠JKL = 1/2 * 130

m∠JKL = 65°

Therefore:

m∠KJL = 180 - 90 - 65 = 25° (sum of angles in a triangle)

the headlights on a car are set so the light beam drops 2 in. for 26 ft measured horizontally. If the headlights are mounted 24 in. above the ground, how far ahead of the car will they hit the ground?>

Answers

Answer:

0.168 ft aprox

Step-by-step explanation:

To solve this problem, we can use similar triangles and proportions. Let's denote the distance ahead of the car where the light beam hits the ground as "x" (in feet).

According to the given information, the light beam drops 2 inches for every 26 feet horizontally. We can set up the following proportion:

2 inches / 26 feet = x inches / x + 26 feet

To solve for x, we can cross-multiply and solve the resulting equation. Let's convert inches to feet to maintain consistent units:

2 inches = 2/12 feet = 1/6 feet

1/6 feet / 26 feet = x feet / x + 26 feet

1/6 * (x + 26) = 26 * x

x/6 + 26/6 = 26x

x + 26 = 156x

156x - x = 26

155x = 26

x = 26 / 155 ≈ 0.168 ft

Therefore, the headlights will hit the ground approximately 0.168 feet (or 2.016 inches) ahead of the car.
