Answer:

A

Step-by-step explanation:

The domain does not exist when the denominater of an equation is zero. So in this case if x was -2 and we added 2 the denominator would be zero, and that value does not exist in the domain. Hope this helps!

The local rodeo has a circular Pin , with a diameter of 48 feet , in which keep the horses what is the circumference or the hors
Alchen [17]

Answer:

The circumference of the horse pin is 150.86 feet

Step-by-step explanation:

In this question, we are to calculate the circumference of the horse pin, given that the diameter is 48 feet.

Mathematically, the circumference can be calculated using the formula

C = 2 * pi * r

where r = D/2 = 48/2 = 24 feet

The circumference C is thus = 2 * 22/7 * 24 = 1056/7 = 150.86 feet

It takes an airplane 5/12 of a minute to fly 3/4 of a mile. What is the airplanes speed per minute?
Nikitich [7]
To make this a little easier, you would want to turn 3/4 into 9/12, to match 5/12's denominator.

You would then just add 7/1 to both fractions

(5/12+7/1=12/12 or 1 minutes)
(9/12+7/1=16/12=1 1/3)

So your answer would be 1.333... miles per minute

Hope this helps
