Let f(x)=8x. The graph of f(x) is transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down.
What is the equation for g(x)?
Enter your answer in the box.
g(x)= ????
Answers
Answer:
g(x) = 32x-7
Step-by-step explanation:
A vertical stretch is shown in an equation by multiplying the equation by a factor greater than 1. Since we are stretching by a factor of 4, we multiply the equation by 4:
g(x) = 4(8x) = 32x
A vertical translation is performed by subtracting a value from a function. To translate the function 7 units down, we will subtract 7 from the equation:
g(x) = 32x-7
The equation for g(x) = 32x - 7.
Given that,
Let f(x) = 8x,The graph of f(x) should be transformed into the graph of g(x) by a vertical stretch of 4 and a translation of 7 units down.Based on the above information, the calculation is as follows:
g(x) = 4(8x)
= 32x
Now here we subtract 7 from the equation.
So, it is g(x) = 32x-7
Therefore we can conclude that the equation for g(x) = 32x - 7.

let x=0, then y=3, so one solution is (0, 3)
let y=0, then x=1 so a second solution is (1, 0)

Here arc = --------------------------------------------------------------
10 - (-10)
10^2 and -(-10)^2 cancel. 18 - 18 cancel.
90 - (-90) 180
This leaves us with arc = ----------------- = ------------- = 9 (answer)
20 20
The average rate of change of the given function is 9.
Given that, a function f(x) = x²+9x+18, we need to find the average rate of change for the function given,
So, the average rate of change = f(b)-f(a) / b-a
Here, a and b are -10 and 10,
So, f(-10) = 100-90+18 = 28
f(10) = 100+90+18 = 208
So, the average rate of change = 208-28 / 10+10
= 180 / 20 = 9
Hence, the average rate of change of the given function is 9.

Clara earns at least $36.75 but not more than $98 working. She earns $12.25 per hour. The number of hours it takes Clara to earn p dollars is modeled by a function. t(p)=p12.25 What is the practical range of the function?
Answers
The range of the function modelling the number of hours it takes clara to earn p dollars is;
A set of all real numbers from 3 to 8
Minimum dollars she earns working; p_min = $36.75
Maximum dollars she earns working; p_max = $98
number of hours it takes her to earn p dollars is given by;
t(p) = p/12.25
Now, range of a function is a set of all possible output values.
Thus, t(36.75) = 36.75/12.25
t(36.75) = 3 hours
Similarly;
t(98) = 98/12.25
t(98) = 8 hours
Since minimum time is now 3 hours and maximum time is now 8 hours, then the range of the function is;
3 ≤ t ≤ 8 which is a set of all real numbers from 3 to 8

The population in Rochester, New York, was 219,773 people in 2000 and 210,565 people in 2010. By about what percent did the population change? Did the population grow or shrink? Write the percent as a decimal.
Answers
Answer:
The population changed by 4.19%. The population shrank.
0.0419.
Step-by-step explanation:
We have been given that the population in Rochester, New York, was 219,773 people in 2000 and 210,565 people in 2010.
[tex]\text{Percent change}=\frac{\text{Final}-\text{Initial}}{\text{Initial}}\times 100[/tex]
[tex]\text{Percent change}=\frac{210,565-219,773}{219,773}\times 100[/tex]
[tex]\text{Percent change}=\frac{-9,208}{219,773}\times 100[/tex]
[tex]\text{Percent change}=-0.04189777\times 100[/tex]
[tex]\text{Percent change}=-4.189777\%[/tex]
[tex]\text{Percent change}\approx-4.19\%[/tex]
Therefore, the population changed by 4.19%.
Since the percent change is negative, therefore, the population decreased or shrank over the given period.
[tex]4.19\%=\frac{4.19}{100}=0.0419[/tex]

Find the slope m of the tangent to the curve y = 8 + 4x2 − 2x3 at the point where x =
a.
Answers
Final answer:
The slope m of the tangent to the curve y = 8 + 4x² - 2x³ at the point where x = a is found by taking the derivative of y with respect to x, which yields m = 8a - 6a².
Explanation:
To find the slope m of the tangent to the curve y = 8 + 4x² − 2x³ at the point where x = a, we first need to compute the derivative of the function y with respect to x. The derivative of a function at a particular point gives us the slope of the tangent line at that point.
The derivative of y with respect to x is given by:
dy/dx = d(8 + 4x² - 2x³)/dx = 8x - 6x²
To find the slope at x = a, we substitute a into the derivative:
m = 8a - 6a²
So, the slope of the tangent line at the point x = a on the given curve is m = 8a - 6a²

Suppose that y varies inversely with x. Write an equation for the inverse variation. y = 4 when x = 6
Answers
The equation for the inverse variation is y = 24/x.
Explanation:In an inverse variation, the equation can be represented as y = k/x, where k is a constant. To find the equation for the given scenario, we can substitute the values of y = 4 and x = 6 into the equation and solve for k.
4 = k/6
Cross-multiplying, we get k = 24. Therefore, the equation for the inverse variation is y = 24/x.
A political polling agency predicts candidate A will win an election with 54% of the votes. Their poll has a margin of error of 4% both above and below the predicted percentage. Which inequality represents the predicted possible percent of votes, x, for candidate A? 50 ≤ x ≤ 58 x ≥ 50 or x ≤ 58 x ≥ 52 or x ≤ 56 52 ≤ x ≤ 56
Answers
The inequality that represents the predicted possible percent of votes is 50 ≤ x ≤ 58
The margin of error (E) shows by how much the measured value can differ from the mean value.
Given that the probability of winning the election is 54% and there is a margin of error of 4%, hence:
Let x represent the predicted possible percent of votes.
x = 54% ± 4%
x = (54% - 4%, 54% + 4%)
x = (50%, 58%)

The predicted possible percent of votes, x, for candidate A considering the margin of error can be represented as follows:
Given:
- Predicted percentage of votes for candidate A = 54%
- Margin of error = ±4%
The predicted range of percentages for candidate A can be expressed as:
[tex]\[ 54\% \pm 4\% \][/tex]
This translates to:
[tex]\[ 54\% - 4\% \leq x \leq 54\% + 4\% \][/tex]
Calculate the lower and upper bounds:
