<span>–0.507x2 + 14.907x – 36.131</span>
Sever21 [200]3 years ago
4 0

The <em>correct answer</em> is:


b.) –0.507x2 + 14.907x – 36.131


Explanation:


First we enter the data into a graphing calculator. The times are the x-coordinates and the temperatures are the y-coordinates; this is because temperature is dependent upon time.


After we enter this, we run a regression on the calculator. We will run the quadratic regression; the equation is of the form

y = ax²+bx+c.


The values we are given on a Casio fx-9860 gii are:

a = -0.507

b = 14.908

c = -36.136


This is closest to choice B.

If f(x) = 2x - 2 and g(x) = x}, what is (gºf)(4)?
Bad White [126]

Answer:

We conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Step-by-step explanation:

Given

f(x) = 2x - 2

g(x) = x

We have to determine (gºf)(4).

(gºf)(4) = g(f(4))

f(4) = 2(4)-2

      = 8 - 2

      = 6

Thus,

(gºf)(4) = g(f(4)) = g(6) = 6

Therefore, we conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Is 290.45 higher than 2867.5
tekilochka [14]
2867.5 is bigger

Even though they both show 5 numbers, the second one has only one decimal place versus 2 on the first

If you ignore the decimal, your left with
290 vs 2867

2867 is much bigger than 290 so this is the answer
