If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?

Burka [1]

$y=kx \\ \\
y=144 \hbox{ when } x=12 \\
\Downarrow \\
144=k \times 12 \\
k=12 \\ \\
y=12x \hbox{ and }
x=17 \\
\Downarrow \\
y=12 \times 17 \\
y=204 \\ \\
\boxed{y=204} \hbox{ when } x=17$

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
