<h3>The answer is option D.</h3>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

Slope of the line using points ( 5 , - 1) and

( - 5 , 2) is

m = 2+1/ -5-5 = - 3 / 10

Equation of the line using point ( 5 , - 1) is

y + 1 = -3/10(x - 5)

y = -3/10x + 3/2 - 1

The final answer is

Hope this helps you.

For what values of the numbers a and b does the function below have maximum value f(1) = 4? (Round the answers to three decimal

Georgia [21]

F (x) = $a x e^{b x^{2} }$
f ` (x) = $a( e^{b x^{2} } +x e ^{b x^{2} } *2 b x )=a e ^{b x^{2} } (1+2b x^{2} )$
f ( 1 ) = 4
f ` ( 1 ) = 0
$4 = a e ^{b} \\ a e ^{b} (1 + 2 b ) = 0 \\ 4 ( 1 + 2 b )= 0
$
b = -1/2
$4=a e ^{-1/2} = \frac{a}{ \sqrt{e} } \\ a = 4 \sqrt{e}$
Answer: a = 4√e, b = -1/2
