Answer:
The radius is 9 cm.
Step-by-step explanation:
The formula for calculating the circumference of a circle is

Where r is the radius and C is the circumference.
It was given in the question that; the circumference,
.
We substitute this into the formula to obtain;

Divide both sides by 


The radius is 9cm
Answer:
Composition of f and g = 6x + 7
Composition of g and f = 6x + 11
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x + 2
f(g(x)) = 2(g(x)) + 3 = 2(3x + 2) + 3 = 6x + 4 + 3 = 6x + 7
g(f(x)) = 3(f(x)) + 2 = 3(2x + 3) + 2 = 6x + 9 + 2 = 6x + 11
( yx + 4x - 5 )( y + 1 )

Step-by-step explanation:
This equation allows you to find out how many visits would create an even rate for both gyms.
Answer:
Step-by-step explanation:
sinD = opposite/hypotenuse = 12/15 = 4/5
cosD = adjacent/ hypotenuse = 9/15 = 3/5
sinE = opposite/hypotenuse = 9/15 = 3/5
cosE = adjacent/ hypotenuse = 12/15 = 4/5
