Answer:
Step-by-step explanation:
The area of the rectangle can be written as:
here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.
The perimeter of a rectangle can be written as:
To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.
now we can substitute this 'h' into our equation of the perimeter.
and voila! we have expressed P in terms of x only.
this can be written as P as a function of x as:
3300 exemption
37,500−3,300=34,200 taxable
Tax rate is
2+3/4=2.75% we don't multiply 2by 3/4
Now calculate the amount of tax
34,200×2.75%=940.5
The opposite of that would be -17

Answer:
The surface area of a sphere is calculated by formula:
A = 4 x pi x radius^2
=> radius = sqrt(A/(4 x pi) = sqrt(4534.16/(4 x pi)) = 19 (cm)
Hope this helps!
