Sr=v
divide both sides by s
r=v/s

When using distributive property for this it’s gonna be 5(5.75+4.25)
So 5•5.75=28.75
5•4.25=21.25
So then 28.75+21.25=50

Write 5% as a decimal.
jolli1 [7]
You cannot do it that way.  Make sure the question you wrote is correct, because you would divide 5 by 100, not 100 by 5.  A simple way is to move the decimal point two points to the left.  5% as a decimal is 0.05.  

The answer is false if the question is written this way.

5. A ball is thrown upward with an initial velocity of 50 feet per second. The
dangina [55]

Answer:

SEE BELOW IN BOLD.

Step-by-step explanation:

a.

h = -16t^2 + 50t

h = 20 t

When the height is the same:

-16t^2 + 50t = 20t

-16t^2  + 30t = 0

t(-16t + 30) = 0

t = 0 or  -16t + 30 = 0, so:

t = 0 or -30/-16 = 1.875

So the answer is 1.88 seconds to the nearest hundredth.

b.

For the ball

h = -16t^2 + 50t

Finding the derivative and equating to zero:

dh/dt = -32t + 50 = 0

t = -50/-32 = 1.563

Maximum height after 1.56 seconds to nearest hundredth

c.

When the ball hits the ground h = 0 so

-16t^2 + 50t = 0

-16t(t - 50/16)= 0

T = 3.13 SECONDS TO THE NEAREST HUNDERDTH
