Answer:

y = 3/2x + 15

Step-by-step explanation:

change f(x) to 'y='

interchange 'x' and 'y' then solve for 'y':

y = 2/3x - 10

x = 2/3y - 10

x+10 = 2/3y

multiply each side by 3/2 to get:

y = 3/2x + 15

Find the volume of a pyramid with a square base, where the perimeter of the base is 7.3\text{ ft}7.3 ft and the height of the py
Cloud [144]

Answer:

V=6.66\ ft^3

Step-by-step explanation:

The perimeter of the square base of a pyramid = 7.3 ft

The height of the pyramid, h = 6ft

The perimeter of a square is given by :

P = 4s, s is the side of square

7.3 = 4s

s = 1.825 ft

The volume of a pyramid is given by :

V=\dfrac{lbh}{3}

Here, l = b = 1.825 ft

So,

V=\dfrac{1.825\times 1.825\times 6}{3}\\\\V=6.66\ ft^3

So, the volume of the pyramid is equal to 6.66\ ft^3.
