Answer:
the domain of the function is negative infinity to positive infinity because an exponent can be any real number
Step-by-step explanation:
3y = 3 * 9 = 27
4z = 4 * -12 = -48
: -48 + 27 = -21
: -21 + x = 24
: X = 45.
I hope that makes sense.
First, get the area of the rectangular yard.
Area = L x W
Area = 16 X 14
Area = 224 square feet
Get the area of the circular fountain.
Area = pi x r^2
Area = 3.1415 x (4/2)^2
Area = 12.57 square feet
Getting grass portion.
224 - 12.57 = (C) 211.43 square feet
