The graph of f(x) = x2 was transformed to create the graph of g(x) = 4x2. Which of these best describes this transformation?

Zinaida [17]3 years ago

Answer:

The graph will become narrower

Step-by-step explanation:

Here, we want to get the transformation that will occur to the graphs

From what we have, there is a a parabolic graph for f(x) initially

Moving on, the f(x) values were multiplied by 4 to give g(x)

For a parabolic graph, the greater the coefficient of x^2, the narrower the graph will be

Since the coefficient of g(x) is greater, it is expected that the graph of g(x) be narrower

the function t(n) 8n represents the number of tires t(n) that are needed for n trucks. if t(n)=200. what is the value of n?
mr_godi [17]

Step-by-step explanation:

if I understand correctly, then the function is

t(x) = 8x

now we know, that for a specific n

t(n) = 200

that means

200 = 8n

n = 200/8 = 25

the function tells us, that for 25 trucks we need 200 tires.

What is the Slope of a line That contains (2,5) and (3, 1) Sketch the graph. Need help with this question.​
Svetach [21]

Answer:

-4/1

Step-by-step explanation:

To find the slope, first plot the two points we are given on the provided coordinate plain. Then using rise/run (slope) find the distance between the two points going up and over or rising and running. So we go up 4 and over 1, this means the slope is 4/1. Since the line we just graphed is going top left towards bottom right, it is negative.

I hope this helps u!! :)

What is the variance of the following data? If necessary, round your answer to two decimal places. 17, 13, 13, 22, 11, 20
Bond [772]
Variance is the standard deviation squared but we're not going to use that now. Let's first calculate the mean:

mean = (17+13+13+22+11+20)/6 = 16.

Now for each value, let's see how far it is from this mean. We'll square these distances and average them. That's our variance.

17 distance 1 squared = 1
13 distance 3 squared = 9
13 distance 3 squared = 9
22 distance 6 squared = 36
11 distance 5 squared = 25
20 distance 4 squared = 16

Now average these outcomes:

variance = (1+9+9+36+25+16)/6 = 16.

So the variance by coincidence is the same as the mean.

Answer C is your answer.
