30 POINTS FOR A CORRECT ANSWER WITH GOOD EXPLANATION Edgar measures the temperature of a solution at the beginning of an experiment to be 23 F. He monitors the temperature of the solution every minute for 10 minutes. He records the change in temperature from his previous reading. His data show a decrease of 2 F four times, a decrease of 3 F three times, no temperature change two times, and an increase of 6 F once.

(A) Write an expression that represents the average change in temperature each minute.

(B) Edgar repeats the experiment and finds the average change in temperature each minute is 1 F greater in the second trial than in the first trial. What is the average change in temperature each minute in the second trial of the experiment? Show your work.

The average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.

Step-by-step explanation:

To A) write an expression that represents the average change in temperature each minute, and B) if Edgar repeats the experiment and finds the average change in temperature each minute is 1 ° F greater in the second trial than in the first trial, to determine what is the average change in temperature each minute in the second trial of the experiment, the following calculations must be performed:

A)

(-2 x 4 + -3 x 3 + 6) / 10 = X

(-8 + -9 + 6) / 10 = X

-11 / 10 = X

-1.1 = X

B)

(-3 x 4 + -4 x 3 + 7) / 10 = X

(-12 + -12 + 7) / 10 = X

-17/10 = X

-1.7 = X

Therefore, the average change in temperature in each minute would be A) -1.1ºF and B) -1.7ºF.

so sorry if wrong

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
