The radius is one half of the diameter.

Divide the diameter by 2 for the radius.

Radius = 4 centimeters / 2 = 2 centimeters.

A cannon ball is launched at 6 feet per second from the top of a platform 12 feet above the ground.

AleksAgata [21]

A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12

b.) The y-intercept is 12

c.) The y-intercept represent the height of the ball at time t = 0

d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.

The lines p and q intersect at point O. What is the value of x? Enter your answer in the box. x = Lines p and q intersect at poi

Answer:

x = 16

Step-by-step explanation

Find the diagram attached. You can see from the diagram that both angles are vertically opposite angles and vertically opposite angles are equal.

Hence 2x+13 = 3x-3

Collect like terms

2x-3x = -3-13

-x = -16

Multiply both sides by -1

-1(-x) = -1(-16)

x = 16

Hence the value of x is 16

The solution for this problem is:
The population is 500 times bigger since 8000/24 = 500. The population after t days is computed by:P(t) = P₀·4^(t/49)
Solve for t: 8000 = 8·4^(t/49) 1000 = 4^(t/49) log₄(1000) = t/49t = 49log₄(1000) ≅ 244 days
