For this case we must find the inverse of the following function:
We follow the steps below:
Replace f(x) with y:
We exchange the variables:
We solve for "y":
Multiply by -2 on both sides of the equation:
We raise both sides of the equation to the square to eliminate the radical:
We subtract 3 from both sides of the equation:
We change y by f ^ {- 1} (x):
Answer:
Answer:
32.4
135 x 24% = 135 x 0.24 = 32.4
Step-by-step explanation:
Answer:
sp with vat=9040
d=20%
vat=13%
mp=?
Step-by-step explanation:
sp with vat=9040
sp+vat%of sp=9040
sp(1+13/100)=9040
sp=9040/1.13=8000
- mp=sp+d%ofmp
- mp-d%ofmp=sp
- mp(1-20/100)=8000
- mp=8000/0.8=10000
Both base and height of the sail is 40 1/2 feet.
A sail is triangular in shape. Finding the area of a triangle is multiplying its base and height and dividing the product by 2.
A = 1/2 bh
Area = 40 1/2 or 40.50 sq. ft
Since base and height are equal.
40.50 x 2 = 81
bh = 81
bh = 81 ÷ 2
b = 40 1/2 ft
h = 40 1/2 ft
Just multpily.
8950*.76= 6820
so C is the answer
