B because absolute value means that the number inside the absolute value brackets is the positive version of the number
Same as the car one
A=Pe^(rt)
when it is a decay, make r negative
P=23781 and r=-0.032 and t=17
A=23781e^(-0.032*17)
A=23781e^(-0.554)
A=13803.01
so about 13803 people is the population after 17 years
Simple way to see it is to multiply the value opposite of the axis you're flipping it over by -1. For example the point (-5,7) would become (5,7) when reflected over the y-axis, because the point is moving from the left to the right. This means the triangle would be (1,3) (5,3) and (5,7) when reflected over the y-axis. For reflection over the x-axis it would be (-1,-3) (-5,-3) and (-5,-7) because each point is moving down.
Answer:

Step-by-step explanation:
From the question we are told that:
Rate 
Height 
Radius 
Generally the equation for Volume of Cone is mathematically given by


Differentiating



F (9)= 5(9) -16
45-16
f(9)=29
