Can someone help point me in the right direction?

Find the rate of change of the area A when h=3, if h is decreasing at a rate of 0.5 units/sec. Write answer as a simplified fraction or expression.

Again, h is decreasing at a rate of dh/dt = -0.5 units/sec. At h=2.9, is the area A increasing or decreasing? How do you know?

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

answerthe vertex form

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
