Petra throws a ball up with an initial vertical velocity of 35 ft/s from a platform that is at ground level.How long will the ball be in the air?

Answers

Answer 1

Answer: The equation used to solve this problem is this:
H(t) = -16t^2 +vt + s
Where,
H(t) is the distance of the ball from the ground in feet,
t is the time in seconds,
v is the initial velocity of the ball as it is thrown up in feet/sec,
s is the distance of the ball from the ground when it was thrown in feet

Plugging in the given values,
0 = 16 t^2 + 35t + 0
This is a quadratic equation and the roots are:
0 and 2.19

ANSWER: 2.19 SECONDS

Answer 2

Answer:

The equation used to solve this problem is this:

H(t) = -16t^2 +vt + s

Where,

H(t) is the distance of the ball from the ground in feet,

t is the time in seconds,

v is the initial velocity of the ball as it is thrown up in feet/sec,

s is the distance of the ball from the ground when it was thrown in feet

Plugging in the given values,

0 = 16 t^2 + 35t + 0

This is a quadratic equation and the roots are:

0 and 2.19

answer: 2.19 seconds

Solve the question: 12y = 132.
A. Y = 144
B. Y = 1/11
C. Y = 11/12
D. Y = 11

Answers

Answer is D. Y=11 12*y-(-132=0
12y+132=12•(y+11)

$12y = 132$

$(12y)/(12) = (132)/(12)$ $Divide \ both \ sides \ by \ 12$

$\boxed{\boxed{y=11}}$ $Solution$

Answers

$7(3x-4)=49$
Distributhing 7 through prantheses
$7*3x-7*4=49$
$21x-7*4=49$
$21x-28=49$
Add28
$21x=49+28$
$21x=77$
Divide by 21
$x= (77)/(21)$

$x= (11* \not7)/(3* \not7)$

$x= (11)/(3)$

$x=3 (2)/(3)$

The number 137.5 is 125% of what number

Answers

125% = 1.25

x * 1.25 = 137.5

x = 110

137.5 is 125% of 110

125% of x =137,5

125/100 * x= 137.5

5/4 *x=137,5

5x/4= 137,5

x=4*137,5/5

x=4*27,5

x=110
