Answer:
4
Step-by-step explanation:
A) Find the inverse of the function
s=0.04n+2500
s-2500=0.04n+2500-2500
s-2500=0.04n
s/0.04-2500/0.04=0.04n/0.04
25s-62,500=n
n=25s-62,500
Answer: The inverse of the function is n=25s-62,500
Is <span>the inverse a function?
Yes, the inverse is a function, a linear function.
</span>b) Use the inverse to find the same amount of merchandise sold if the employees salary was $2820 last month.
s=2,820→n=25(2,820)-62,500
n=70,500-62,500
n=8,000
Answer: The amount of merchandise sold was $8,000
Answer:
So I', just guessing you are solving for why.
y=5+2x
Step-by-step explanation:
Basically you move all the numbers that don't have why on to the other side of the equation and vice versa if you are solving for x.
Answer:
-4x^2+3x
Step-by-step explanation:
collect like terms
(2x^2-6x^2) + (6x-3x) + (5-5)
simplify
-4x^2 + 3x
The volume of a volleyball with radius 11.1 cm is 5731.025 cubic centimeter
<h3><u>Solution:</u></h3>
Given that volume of a sphere is a function of its radius
Radius = 11.1 cm
<em><u>To find: volume of a volleyball</u></em>
Since volleyball is generally of spherical shape, we can use volume of sphere formula
Where "r" is the radius of sphere and 
is a constant which has value 3.14
<em><u>Substituting the given radius r = 11.1 cm</u></em>
volume of sphere = 5731.025 cubic centimeter
Thus the volume of volleyball is 5731.025 cubic centimeter
