First, find the circumference of the wheel using

You know that your diameter is 24. To find the radius, divide the diameter by 2, which is 12.
Input 12 as r and simplify. ->


estimate your Pi as 3.14

and multiply. C=75.36
Now you know the distance of one full revolution in inches. To find 200 revolutions, multiply that answer by 200.
75.36 * 200 = 15,072 inches
But because this is in inches, you have to find the answer in feet, so just divide that answer by 12.
15,072 / 12 = 1,256 ft
Step-by-step explanation:
domain = {-7, -3, 1}
range ={-8, -5, 7, 8}
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.
<h3>Equation for
speed</h3>
Speed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent Karen speed and b represent Melinda speed, hence:
a = b + 10
a - b = 10 (1)
Also:
a = d₁ / 1
d₁ = a
b = d₂/ 1 hour
d₂ = b
Since they are 108 miles apart, using Pythagoras:
108² = d₁² + d₂²
a² + b² = 11664
(b + 10)² + b² = 11664
b = 71.2 mph, a = 81.2 mph
Karen is moving at 81.2 miles per hour while Melinda is moving at 71.2 miles per hour.

Answer:
hi
Step-by-step explanation:
for example

in the second one you should multiple 5 and 1 then add 4
(x - 2)^2 will always be positive and will have a minimum value of 0
so f(x) will have minimum of 2
Range is [2,∞)
