The function H(t) = −16t2 + 75t + 25 shows the height H(t), in feet, of a baseball after t seconds. Part A: After how many secon

nlexa [21]

Step-by-step explanation:

Given that,

The function that shows the height of a baseball after t seconds is given by :

$H(t)=-16t^2+75t+25$ ....(1)

Part (A).

When the baseball hits the ground,

H(t) = 0

So,

$-16t^2+75t+25=0\\\\t=5\ s\ and\ t=-0.31\ s$

After 5 seconds the baseball will hit the ground.

Pat (B)

For maximum height, put dH/dt = 0

So,

$\dfrac{d}{dt}(-16t^2+75t+25)=0\\\\-32t+75=0\\\\t=2.34\ s$

Put t = 2.34 s in equation (1).

$H(t)=-16(2.34)^2+75(2.34)+25\\\\H(t)=112.89\ m$

Hence, this is the required solution.

Circle V is shown. Line segment T V is a radius with length 14 feet.

lawyer [7]

We have been given graph of circle V with radius 14 feet. We are asked to find the area of the circle V.

We will use area of circle formula to solve our given problem.

$A=\pi r^2$ , where r represents radius of circle.

Upon substituting $r=\text{14 ft}$ in above formula, we will get:

$A=\pi(14\text{ ft})^2$

$A=\pi(14)^2\text{ ft}^2$

$A=\pi\cdot 196\text{ ft}^2$

$A=196\pi\text{ ft}^2$

Therefore, the area of the circle V is $196\pi$ square feet and option 'c' is the correct choice.

Yuliya22 [10]

You have to calculate how many ways you can select six things (r)
from a set of 9 things (n). (See attached formula).

9! / 6! * (3!) =
9*8*7 * 6! / 6! * 3! =
9*8*7 / 3! =
3 * 4 * 7 = 84 lineups

The length of each square on the grid represents 1 cm. The scale

tatyana61 [14]

Answer:

Step-by-step explanation:

Length of the rectangle given in the the figure attached = 2 cm

Width of the rectangle = 5 cm

Scale used, 24 in to 1 cm

Therefore, length of actual rectangle = 2×24 = 48 in

width of the actual rectangle = 5×24 = 120 in

Now we have to draw a drawing by using the scale,

16 inches to 1 cm

Or 1 inch = $\frac{1}{16}$ cm

Therefore, length of the rectangle drawing = $48\times \frac{1}{16}$

= 3 cm

Similarly, width of the rectangle drawing = $120\times \frac{1}{16}$

= 7.5 cm
