Answer:
7.33 * 10^-11 s
Step-by-step explanation:
Period, T = 1 / f
c = fλ
λ = 2.20 × 10^–2 m
c = speed of light = 3 * 10^8 m
f = c / λ
f = 3 * 10^8 ÷ 2.20 × 10^–2 m
f = (3/2.2) * 10^(8-(-2))
f = 1.364 * 10^10
T = 1/f
T = 1 / 1.364 * 10^10
T = 7.33 * 10^-11 s
Answer: 800
Step-by-step explanation:
Given: The total number of seats in the stadium : 
The fraction of tickets of seats sold : 
To find the number of tickets it sold , we need to multiply the fraction of tickets of seats sold to the total number of seats in the stadium , we get
The number of tickets of seats sold : 
Hence, the number of tickets of seats sold : 800
Answer:
Step-by-step explanation:
The equation that models the height of the ball in feet as a function of time is

Where
is the initial height,
is the initial velocity and t is the time in seconds.
We know that the initial height is:
The initial speed is:

So the equation is:

The ball hits the ground when when
So

We use the quadratic formula to solve the equation for t
For a quadratic equation of the form

The quadratic formula is:

In this case

Therefore

We take the positive solution.
Finally the ball takes 2.47 seconds to touch the ground
Since the whole thing is 24x+8, it is divided in 2 parts so both of those must be equal to the whole one. You get:
14x-2+70=24x+8
10x=60
x=6
Find the length of each side using the distance formula:, then add all three side length for the perimeter.
Area is found by multiplying the base by the height by 1/2.
