The correct answer is A.
For y=x, the slope is 1, meaning that as x increments by 1, y also increments by 1.
Using this logic, we know that the graph goes up looking from left to right.
If both ends were to point up or down it would resemble more of a quadratic (parabola).
The expression is not factorable with rational numbers.
Three ventilation fans, each working alone, can clear the smoke out of a room in 12 hours, 16 hours, and 24 hours respectively. How long would it...
Answer:
C = 37.7 inches
Step-by-step explanation:
You are looking for the circumference.
Formula for the circumference-> C=2πr
variables:
c = circumference
r = radius
You have the diameter, which is 12 inches. Radius is half of the diameter. which means r is half of 12 (aka 6).
put the radius where the variable is in the formula.
C=2π(6)
you now have enough information to solve for circumference.
C = 2 * π * 6
C = 37.7
