A diver is standing on a platform 24 feet above the pool. He dives form the platform with an initial upward velocity of 8 feet p
Mazyrski [523]

Answer:

It should be t = 1.5 seconds  if your equation is  h(t)  = -16*t^2 + 8t + 24

Step-by-step explanation:

h(t)  = -16*t^2 + 8t + 24

We want  to solve for t when h(t) = 0.

This is a parabolic equation so basically we can use the quadratic formula to solve this.

h(t)  = -16*t^2 + 8t + 24

0 = h(t)  = -16*t^2 + 8t + 24

take out the 8

0 = -2t^2 + t + 3

0 = -2t*t  - 2t  + 3t + 3

0 = -2t * (t + 1)  +  3*( t + 1)

0 = (-2t + 3) * ( t + 1)

so time cannot be negative, so we choose  0 = (-2t + 3),   t = 3/2 seconds

or  t = 1.5 seconds

Find the volume in terms of pi of a sphere with a surface area of 9 pi square feet
Drupady [299]
So we want to know the volume of a sphere in terms of pi if we know the area of the sphere is equal to A=9pi. So the area of the sphere is A=4*pi*r^2 and the volume V=(4/3)*pi*r^3. We can get the radius from the area: 9pi=4*pi*r^2 and we see the pi cancels out: 9=4*r^2. We divide by 4 and take the square root: r=sqrt(9/4)=3/2. So r=3/2 and we can input it into volume V.

V=(4/3)*(3/2)^3*pi=(4/3)*(27/8)*pi=(9/4)*pi. 

So the volume of the sphere is V=(9/4)*pi cubic feet.

600 sixth-graders were surveyed.

Step-by-step explanation:

Step 1; Assume x is the total number of sixth-graders that were surveyed. According to the given circle graph, 5% of the sixth-graders that were surveyed have birds as their pets. If x is the total number of sixth-graders surveyed then 5% of x equals 30. So

5% of x = 30.

5% equals \frac{5}{100} = 0.05, so 5% = 0.05.

Step 2; If 0.05 x = 30, we can solve by keeping the unknown value on one side and keeping all the known values on one side.

x = \frac{30}{0.05} = 600.

So 600 sixth-graders were surveyed.
