Answer:

x = 85°

Step-by-step explanation:

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate

andriy [413]

Answer:

The average rate of change

$\frac{dh}{d t} = 70 (1) - 16(2t)$

At t = 1

$\frac{dh}{d t} = 70 (1) - 16(2t) = 38$

at t=3

Step-by-step explanation:

Step(I):-

The given function h(t) = 3+70t - 16t²

$\frac{dh}{d t} = 70 (1) - 16(2t)$

The $\frac{dh}{d t} = 70 (1) - 16(2t) =0$

70 - 32 t = 0

⇒ 70 = 32 t

⇒ $t = \frac{70}{32} = \frac{35}{16}$

Step(ii):-

The average rate of change in h(t) between t = 1 second and t = 3 second

$\frac{dh}{d t} = 70 (1) - 16(2t)$

At t = 1

$\frac{dh}{d t} = 70 (1) - 16(2t) = 38$

At t = 3

Which of the following is NOT an integer? 4.5 8 -7 0

Marrrta [24]

A integer is a whole number that does not contain a fraction. Therefore, A is the correct answer because it is a decimal. I understand it could have been hard to determine between 0 and 4.5, but just remember, if there is a decimal or fraction, it is not a integer. Hope this helped!

What is the equation of the axis of symmetry of this parabola? y=-5(x+4)^2+3

Ede4ka [16]

Answer:

$x=-4$

Step-by-step explanation:

Given the equation of parabola

$y=-5(x+4)^2+3$

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point $(-4,3)$

This parabole goes downwards in y-direction (the leading coefficient -5 is negative)

The axis of symmetry of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Thus, the equation of the axis of symmetry is

$x=-4$
