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:

<u><em>Step(I)</em></u>:-

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}

<em>Step(ii</em>):-

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?<br><br> 4.5<br><br> 8<br><br> -7<br><br> 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)

<u>The axis of symmetry</u> 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
