A tennis ball is launched from a catapult from the ground with an initial velocity of 26fps. What is the maximum height of the b

Lady bird [3.3K]

Answer:

10.5618feet, 0.8125sec

Step-by-step explanation:

Given the height reached by the catapult expressed by the equation H=-16T^2+26T

At the maximum height, the velocity of the object is zero, hence;

v = dh/dt = 0

-32t + 26 = 0

-32t = -26

t = 26/32

t = 0.8125secs

Hence it will attain the maximum height after 0.8125second

Substitute t = 0.8125s into the expression to get the maximum height

H=-16t^2+26t

H = -16(0.8125)^2 + 26(0.8125)

H = -16(0.6602) + 21.125

H = -10.5632+21.125

H = 10.5618

hence the maximum height reached by the ball is 10.5618feet

The length of a rectangle is 11m more than twice the width, and the area of the rectangle is 63m^2 . find the dimensions of the

gulaghasi [49]

(7/2) m is the width and 18m is the length. This is because area is lxw.let w= width and length=11+2wMultiply together, get 2w^2+11w-63=0factor to get (2w-7)(w+9).Find w and get w=7/2 and w=-9Negative rejected because a measurement can't be negative. Finally substitute that into the length equation (11+2w) to get 18m and width is 7/2 m

I forgot how to do this so please help me.

Makovka662 [10]

Answer:

Draw a straight line that goes through the point (0,4) and (20,0)

Step-by-step explanation:

The y-intercept is equal to 4, since the function is already in y=mx+b form, where b is the y-intercept.

To find the x-intercept, we substitute 0 into y or in this case the f(x).

0 = -1/5 (x) + 4

1/5 x = 4

x = 20

The x-intercept is 20.

What is the area of a circle with a diameter of 37 inches?

krek1111 [17]

Hello!

To find the area of a circle you use the equation

$\pi r^{2}$

r is the radius which is half the diameter

$\pi 18.5^{2}$

Square 18.5

$\pi *342.25$

Put this into the calculator and you get the answer of about 1075.21

The answer is about 1075.21

Hope this helps!
