A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=72t-16t^2. What is the

irakobra [83]

Answer:

The maximum height that the ball will reach is 81 ft

Step-by-step explanation:

Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.

For an equation of the form

$at ^ 2 + bt + c$

the t coordinate of the vertice is:

$t =-\frac{b}{2a}$

In this case the equation is:

$h(t)=72t-16t^2$

$a=-16\\b=72\\c=0$

Therefore

$t =-\frac{72}{2(-16)}$

$t=2.25\ s$

Finally the maximum height that the ball will reach is

$h(2.25)=72(2.25)-16(2.25)^2$

$h=81\ ft$

The intensity I of light varies inversely as the square of the distance D from the source. If the intensity of illumination on a

zhenek [66]

Answer:

The intensity on a screen 70 ft from the light is 1.728 foot candle.

Step-by-step explanation:

Given that,

The magnitude of intensity $I$ of light varies inversely as the square of the magnitude of distance D from the source.

That is

$I\propto \frac{1}{D^2}$

Then,

$\frac{I_1}{I_2}=\frac{D_2^2}{D_1^2}$

Given that,

The magnitude of intensity of illumination on a screen 56 ft from a light is 2.7 foot-candle.

Here,

$I_1$ =2.7 foot-candle, $D_1$ = 56 ft

$I_2$ =?, $D_2$ = 70 ft.

$\frac{I_1}{I_2}=\frac{D_2^2}{D_1^2}$

$\Rightarrow \frac{2.7}{I_2}=\frac{70^2}{56^2}$

$\Rightarrow \frac{I_2}{2.7}=\frac{56^2}{70^2}$

$\Rightarrow {I_2}=\frac{56^2\times 2.7}{70^2}$

$\Rightarrow {I_2}=1.728$ foot-candle

The intensity on a screen 70 ft from the light is 1.728 foot candle.

Answer:

B. The graph of G(x) is the graph of F(x) stretched vertically, flipped over the x-axis, and shifted 4 units to the left.

Step-by-step explanation:

The $\frac{-1}{3}$ is less than one, making it stretch wider, and the (-) made it flip over the x-axis. The +4 in $(x+4)^2$ made the function on the graph shift 4 units to the left.

<u>This makes the correct answer be "B."</u>

In a recent year, 32.3% of all registered doctors were female. If there were 46,300 female registered doctors that year, what wa

lesya [120]

Answer:

143,344

Step-by-step explanation:

Let d represent the total number of registered doctors. The given relation is ...

0.323d = 46,300

Dividing by the coefficient of d, we get ...

d = 46,300/0.323 ≈ 143,343.7

The total number of registered doctors was about 143,344.
