Step-by-step explanation:
Answer:
44 attempts
Step-by-step explanation:
What is a ratio?A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.
The ratio for this problem is:
2: 11 (field goals missed: total attempts)To get from 2 to 8, we multiply the 2 by 4.
2 × 4 = 8The ratio is now:
8:?To solve for '?', we can simply multiply the 11 by 4, just like what we did with the 2.
11 × 4 = 44Now the ratio is:
8: 44If the ratio has 44 as the second number, we know that it is the total attempts. Therefore, he attempted 44 field goals.
Work out the equation of the straight line that passes through (5, 4) and (8, 19). Give your answer in the form y = mx + c, where m and c are integers or fractions in their simplest forms.
Answer:
y = 5x - 21
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 4 ) and (x₂, y₂ ) = (8, 19 )
m = [tex]\frac{19-4}{8-5}[/tex] = [tex]\frac{15}{3}[/tex] = 5 , then
y = 5x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, 4 ) , then
4 = 5(5) + c = 25 + c ( subtract 25 from both sides )
- 21 = c
y = 5x - 21 ← equation of line

the total number of people who know about the proposal 5 days after it was announced is 810.
The term [tex]3^ (t-1)[/tex] represents the number of people who find out about the proposal on day t, which is equal to three times the number of people who knew about it on the previous day. The initial value of 10 represents the number of people who knew about the proposal on the first day.
For example, if we want to find out how many people know about the proposal 5 days after the celebrity proposes, we can plug t=5 into the formula:
N(5) =[tex]10* 3^(5-1)[/tex] = [tex]10*3^4[/tex] = [tex]10*81[/tex] = 810
So the total number of people who know about the proposal 5 days after it was announced is 810.
the complete question is :
Assuming that the 10 people who know about the proposal on the first day do not forget or tell anyone else, we can use the following function to calculate the total number of people who know about the proposal t days after the celebrity proposes:
N(t) = [tex]10 * 3^(t-1)[/tex]

At a factory, two machines pack bottles into boxes for shipping. Machine A can pack 8 boxes per minute, and Machine B can pack 11 boxes per minute. Both machines have been packing boxes for some time, and the difference between the number of boxes that Machine B has packed and the number of boxes that Machine A has packed is less than 200. Write and solve an inequality to find the possible lengths of time to the nearest second that the machines have been working. Describe the possible solutions.
Machines A and B worked for 66 minutes and 6 seconds.
What are inequalities:An inequality is a mathematical statement that compares two quantities using one of the inequality symbols: "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).
Inequalities can be solved just like equations, with the goal of finding the set of values that satisfy the inequality.
Here we have
Machine A can pack 8 boxes per minute, and Machine B can pack 11 boxes per minute.
Let Machines A and B work for 'x' minutes
Number of boxes packed by Machine A = 8x
Number of boxes packed by Machine B = 11x
The difference between the number of boxes that Machine B has packed and the number of boxes that Machine A has packed is less than 200.
=> | 11x - 8x| < 200
=> 3x < 200
Divide by 3 into both sides
=> 3x/3 < 200/3
=> x < 66.67
=> x < 66.6
Therefore,
Machines A and B worked for 66 minutes and 6 seconds.

a 25-ft long ladder is leaning against the wall of a house when its base starts to slide away. the base of the ladder is moving away from the house at the rate of 2 ft/sec. how fast is the top of the ladder sliding down the wall when its base is 15 feet from the wall?
The top of the ladder is sliding down the wall at the rate of 1.5 ft/s.
Given: A ladder is 25 ft long and is leaning against the wall of a house.
The base of the ladder is sliding away from the house at the rate of 2 ft/sec.
Asked: How fast is the top of the ladder sliding down the wall when its base is 15 feet from the wall?
Let the distance of the top of the ladder from the wall be x ft.
Then we have,
x² + y² = 25² (by Pythagoras theorem)
Differentiating both sides with respect to time t,
we get, 2x(dx/dt) + 2y(dy/dt) = 0 ...(1)
Given dx/dt = 2, and x = 15 ft.
⇒ 2(15)(dx/dt) + 2y(dy/dt) = 0
⇒ 30 × 2 + 2y(dy/dt) = 0 (substituting the given values)
⇒ 2y(dy/dt) = - 60⇒ dy/dt = - 30/ y
The negative sign indicates that y is decreasing (getting smaller) with time.
The values of y are negative because it lies below the level of the ground.
Substituting the value of x = 15 in the equation x² + y² = 25², we get
15² + y² = 25²
⇒ y² = 25² - 15² = 400
⇒ y = - 20
Substituting the values of dy/dt and y in the above equation, we get,
dy/dt = - 30/ (- 20)
dy/dt = 1.5 ft/s

The answer of the given question based on finding the area of the shaded sectors the answer is approximately 18.8 + 4.2 = 23.0 square units.
What is Angle?An angle is geometric figure formed by the two rays or lines that share common endpoint, called vertex. The rays or lines are often referred to as arms or sides of angle
We need to know the central angles of each sector. We can find these angles by using the formula:
angle = (arc length / radius) * (180/π)
where π is pi, approximately equal to 3.14.
Therefore, we can use trigonometry to find angle EOB:
sin(EOB) = EB/OA
sin(EOB) = 10.4/8
EOB = sin^-1(10.4/8)
EOB ≈ 56.7° degrees
Since angle EOA is a right angle, we know that angle AOB is 90° degrees, so angle AOE is 90 - EOB = 33.3° degrees.
Now, we can find the area of each sector using the formula:
area = (angle/360) * π * r²
Area of shaded sector ADE:
angle AOE = 33.3° degrees
radius = OA = 8
area = (33.3/360) * π * 8²
area ≈ 18.8 square units
Area of shaded sector EBC:
angle EOB = 56.7° degrees
radius = EB/2 = 5.2
area = (56.7/360) * π * 5.2²
area ≈ 4.2 square units
Therefore, the total area of the shaded sectors is approximately 18.8 + 4.2 = 23.0 square units.

An angle measuring (468n)° is in standard position. For which value of n will the terminal side fall on the x-axis?
n = 4
n = 5
n = 6
n = 7
Answer:
n=5
Step-by-step explanation:
Standard Position of the Angle =(468 n)°
We have to find that value of, n for which terminal side will fall on X axis, that is the angle should be multiple of 180°.
You must be thinking why not multiple of ,360°, because factors of 360 are , 90,180,and 360, in which , multiple of 90 falls on x and y axis ,and multiple of 180 ,falls on X axis only.So, instead of taking factors of 90 or 360, you should take multiple of 180° for which terminal side fall on the x-axis.
The Unit Digit of , (468 n)°,should be equal to 0, as it is divisible by number 180°.
For, n=5,
→468° × 5=2340°
So, 2340° , is divisible by 180°.
For, n=5, the terminal side ,the angle having Measure (468 n)°,will fall on the X axis.

Rhonda kept track of the cats at a shelter where she volunteers. She measured how many times per day each cat ate, and she also ranked their activity level on a scale from 1 to 10 each day. She found the line of best fit for the data has the equation y=0. 23x+4. 1, where x represents the activity level and y represents the number of meals eaten.
If a cat had an activity level of about 9, then it's likely to have eaten about _[blank]_ meals.
Enter the value that correctly fills in the blank.
Round to the nearest whole number, if necessary, like this: 42
A cat would probably have consumed about 6 meals if its activity level had been around 9.
A linear equation is a relation between two variables in which one is dependent on the other in such a manner that changing one of the variables causes the change in another variable "linearly".
The above statement can be represented mathematically as,
y=mx+b
where m represents the rate of the change and c is the initial value of the equation.
Let x stand for activity level and y for the number of meals consumed. Therefore:
y = 0.23x + 4.1
For an activity level of 9, we will put x as 9:
y = 0.23(9) + 4.1 = 6.17
Thereby, we can say that If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

The distance of Ken’s house from the park cannot be determined without knowing the distance of the school and the pet shop from the park, and other factors such as terrain, local roads, and traffic can also affect the distance between Ken’s house and the park.
What is distance?Distance is the amount of space between two points. It is a physical quantity that can be measured in various units such as meters, kilometers, miles and light-years. Distance can be calculated using the formula d = s × t, where d is the distance, s is the speed, and t is the time.
Ken lives at a point between the school and the pet shop, so it is impossible to answer this question without knowing how far away the school and the pet shop are from the park. If the park is close to the school or the pet shop, then Ken’s house would be close to the park, but if the park is further away from the school or the pet shop, then Ken’s house would be further away from the park. Therefore, the distance of Ken’s house from the park cannot be determined unless the distances of the school and the pet shop from the park are known.
In addition, other factors such as terrain, local roads, and traffic can also affect the distance between Ken’s house and the park. For example, if there is a hilly terrain between Ken’s house and the park, then the distance between them may be greater than if the terrain were flat.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $2000 and his stock in Company B was worth $4240. The stock in Company A has increased 1% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
The total percentage increase in the investor's stock account is 3.7%.
What is percentage?a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
According to given information :The initial total value of the investor's stock account was $2000 + $4240 = $6240.
The new value of the stock in Company A is 1% more than last year's value, which means it is worth 1/100 * $2000 = $20 more than last year. Therefore, its new value is $2000 + $20 = $2020.
The new value of the stock in Company B is 5% more than last year's value, which means it is worth 5/100 * $4240 = $212 more than last year. Therefore, its new value is $4240 + $212 = $4452.
The new total value of the investor's stock account is $2020 + $4452 = $6472.
To calculate the percentage increase, we need to find the difference between the new and old values and express it as a percentage of the old value:
Percentage increase = ((New value - Old value) / Old value) x 100%
= (($6472 - $6240) / $6240) x 100%
= 3.7% (rounded to one decimal place)
Therefore, the total percentage increase in the investor's stock account is 3.7%.

The exponential regression equation that fits the given data points is y = [tex]4*3^(x-1).[/tex]
The exponential regression equation that fits these data is y = 4*3^(x-1). To calculate this, we need to first calculate the parameters a and b for the equation y = a*b^x. We can do this by finding the natural logarithm (ln) of both sides of the equation.
ln(y) = ln(a*b^x)
ln(y) = ln(a) + ln(b^x)
ln(y) = ln(a) + x*ln(b)
We can now calculate the parameters a and b by plotting the points (x, ln(y)) and performing a linear regression on the points.
ln(4) = 0.602
ln(8) = 2.079
ln(27) = 3.526
ln(85) = 4.443
ln(250) = 5.52

The linear regression equation is ln(y) = 0.175x + 0.602. We can now solve for the parameters a and b by using the linear regression equation.
ln(a) = 0.602
a = e^0.602
a = 4
ln(b) = 0.175
b = e^0.175
b = 3
Therefore, the exponential regression equation that fits these data is y = 4*3^(x-1).

The difference is not constant, the sequence is not arithmetic.
What exactly is an algebraic sequence?An arithmetic sequence is a set of integers where each term is created by multiplying the preceding term by a fixed constant value (known as the common difference). A constant rate of change is modelled by arithmetic sequences in fields like engineering, physics, and financial computations.
For the given series we need to determine if the sequence is arithmetic, by checking difference between consecutive terms is constant.
9 - 7 = 2
12 - 9 = 3
16 - 12 = 4
Since the difference is not constant, the sequence is not arithmetic.
