Answer:
82.5 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 7.5, b₁ = 7 and b₂ = 15 , then
A =
× 7.5 × (7 + 15) = 0.5 × 7.5 × 22 = 82.5 ft²
Answer:
y = 14 
Step-by-step explanation:
For an exponential function of the form y = a
Use the given points to find a and b
Using (0, 14 ), then
14 = a
(
= 1 ) , thus
a = 14
y = 14
Using (3, 3024 ) , then
3024 = 14 b³ ( divide both sides by 14 )
216 = b³ ( take the cube root of both sides )
b =
= 6 , thus
y = 14 ×
← exponential function

36
Step-by-step explanation:
To find the answer, you will just subtract 4.56 from 10.
Answer:
Step-by-step explanation:
159.39(1-25/100)
159.39(100-25)/100
159.39(75)/100
159.39(0.75)
$119.54
