Answer:

f(x) should be reflected across the y-axis
f(x) should be horizontally translated

Step-by-step explanation:

We imagine Jenessa's elevation plots might look like those in the attachment. The red graph would be of f(x) when preparing for the race, and the green graph would be f(x) during the race.

The green graph is not a simple reflection or translation of the red graph, but is a combination of both. Thus, the two answer choices shown above are both applicable.

The sales at a particular bookstore grew from $2006 million in 2000 to $3803 million in 2005. Find an exponential function to mo

Mariana [72]

Yes initial amount is 2044 (in millions)

Since the function is from 2000 then you can set it up as
B(t)=2044*a^t

To solve for "a" use the second number given, 3846, and since this value is 5 years after 2000 t=5
so we plug in these values
3846=2044*a^5

we now solve for a

first, divide by 2044
3846/2044=a^5

next, we take the 5th root
<span>5sqrt(3846/2044) = a

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

stepan [7]

Answer:

A. 71/2 = 35.5 + 32/3= 10.7 + 41/4= 10.3

35.5 + 10.7 + 10.3 = 56.5

B. 21÷2 = 10.5

56.5 ÷ 10.5 = 5.380952381

Consider the sequence following a minus 8 pattern: 9, 1, −7, −15, ….

photoshop1234 [79]

Answer: -287

Step-by-step explanation:

The given pattern: 9, 1, -7, -15, ….

We observe that ,

First term : a=9

Common difference between the terms= 1-9=-8

For Arithmetic sequence , the formula to find the nth term is given by :-

$a_n=a+(n-1)d$

Then, 38th term will be :-

$a_{38}=9+(-8)(38-1)\\\\=9-8(37)=9-296=-287$

Hence, the 38th term of the sequence.= -287

scoundrel [369]

Answer:

With a score of 70, he scored better than 50% of the people who took the test.

Step-by-step explanation:

What a percentile means?

When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.

What does it mean that an individual makes a 70 on a test and this score corresponds to the 50th percentile?

It means that 50% of the students scored 70 or higher, and 50% of the students scored 70 or lower.

So the correct answer is:

With a score of 70, he scored better than 50% of the people who took the test.
