Answer:
B
Step-by-step explanation:
<u>Slope-intercept form:</u>
y= mx +c, where m is the slope and c is the y-intercept.
Given that the slope is -4/5,

To find the y-intercept, substitute a pair of coordinates.
When x= -5, y= -4,

Thus, the equation of the line is

Answer:
g(f(x)) = 9x² + 12x + 5
Step-by-step explanation:
g(f(x))
= g(3x + 2) ← substitute x = 3x + 2 into g(x)
= (3x + 2)² + 1
to expand (3x + 2)² = (3x + 2)(3x + 2)
each term in the second factor is multiplied by each term in the first factor
3x(3x + 2) + 2(3x + 2) ← distribute both parenthesis
= 9x² + 6x + 6x + 4 ← collect like terms
= 9x² + 12x + 4
then
g(f(x)) = (3x + 2)² + 1 = 9x² + 12x + 4 + 1 = 9x² + 12x + 5
It is real sly hard but I am sorry I can I think it is boys
Answer:
The volume is changing at a rate given by:

Step-by-step explanation:
Let's recall the formula for the volume of acone, since it is the rate of the cone changing what we need to answer:
Volume of cone = 
where B is the area of the base (a circle of radius R) which equals = 
and where H stands for the cone's height.
We apply the derivative over time operator (
) on both sides of the volume equation, making sure that we apply the rule for the derivative of a product:
