An object is launched into the air. The projectile motion of the object can be modeled using the function h(t) = –16t2 + 72t + 5

, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds. What is true about the projectile motion of this object? Check all that apply.

Answer:

Step-by-step explanation:

Given that an object is launched into the air. The projectile motion of the object can be modeled using the function

h(t) = –16t^2 + 72t + 5,

h(0) = 5

i.e. initial height =5

h'(t)= -32t+72

Hence velocity =0 when t = 9/4=2.25 seconds

After 2.25 seconds it will start coming down

Maximum height = h(2.25) = -16(2.25)^4+72(2.25_+5

= -81+162+5

=86

Analyze tables use the table that shows the percents of blood types of 145 donors during a recent blood drive
Alenkinab [10]

Answer:

a. 16

b. 80

c. Blood type AB

Step-by-step explanation:

Given:

O = 45%

A = 40%

B = 11%

AB = 4%

Total number of donors = 145

a. No. of donors that had type B blood = \frac{11}{100}*145 = \frac{1,595}{100} = 15.95

Type B blood donors ≈ 16

b. No. of blood donors without blood type O = \frac{40 + 11 + 4}{100}*145 = \frac{55}{100}*145 = \frac{7,975}{100} = 79.75

Those without blood type O ≈ 80

c. Find the number of people that had type AB:

Type AB = \frac{4}{100}*145 = 5.8 ≈ 6. This is less than 10 donors.

Therefore, blood type AB had less than 10 donors.

Add the above answers (4.5 plus 3)

Then multiply by 2 (7.5 times 2)

It equals 15

I hope this helps and that this is the right problem. There is no picture shown but I just did this problem for someone else so I thought I would take a shot at it :)
