Black_prince [1.1K]

Answer: 829.44 ft²

Step-by-step explanation:

Correction - The walkway is 31.2 feet wide.

To solve this, first find the area of the fountain:

Area of a square = Length * Width

= 12 * 12

= 144 ft²

The find the area of the walkway including the fountain:

= 31.2 * 31.2

= ‭973.44‬ ft²

To find the area of the walkway alone, subtract the area of the square from the area of the rectangle:

= 973.44 - 144

= 829.44 ft²

What is the range of the function y= e4x?
Ray Of Light [21]

Answer:

Range is y > 0

Step-by-step explanation:

We need to find the range of y = e^4x

The range is defined as a set of values of dependent variable for which the function is defined.

The exponential function of form c. n^x + k has range f(x) > k

in the given function y = e^4x ,k =0

so Range is y > 0

Work:

(4/3 + 2/3) + 2

4/3 + (2/3 + 2)
