Answer:
Step-by-step explanation:
When x = 0, y = 17 So,
Now,
When x = 5, y = 4131 So,
b = 3
Therefore,
Answer:
volume of trapezoidal prism = 15x^2 cubic units
Step-by-step explanation:
First, area of the trapezoidal bases.
Parallel sides measure x and 2x, for an average of 1.5x.
Height = x
Area of trapezoidal base = 1.5x*x = 1.5x^2
Volume of prism = area base * height
(length does not matter, height does)
= 1.5x^2 * 10 = 15x^2
Answer:
the fence needed to enclose the garden = 140 ft.
Step-by-step explanation:
given:
rectangular garden is 25 ft. by 45 ft.
find:
how many feet of fence are needed to enclose it?
use the perimeter of a rectangle formula = 2L + 2W
let L = 45 ft.
let W = 25 ft.
plugin values into the formula
P = 2L + 2W
P = 2(45) + 2(25)
P = 90 + 50
P = 140 ft.
therefore,
the fence needed to enclose the garden = 140 ft.
To find the answer you have to do 75x0.12
This will give you the amount she saved.
Hope this helped and have a nice day!!!
