For this case we must find
By definition we have to:
We have the following functions:
Now, applying the given definition, we have:
Answer:
The function that describes the fund that was raised is 0.05³ - 30x - 12425
<h3>How to solve for the function</h3>
The revenue is R (z) = 0.05x³ + 75
the cost = C(z) = 30x + 12,500.
Please note that the equation for revenue missed a sign in the question so I made use of the plus sign
We would have revenue - cost
Hence ( 0.05x³ + 75) - (30x + 12,500)
We would open the bracket
0.05x³ + 75 -30x -12500
We would take the like term to
0.05³ - 30x -12500 + 75
0.05³ - 30x - 12425
The function that describes the fund that was raised is 0.05³ - 30x - 12425

There are 10^5 ways.
10&5 - 10^4 = 9 * 10^4 = 90,000
Answer:
34625
Step-by-step explanation:
Answer: 9
Step-by-step explanation:
let the two-digit number has the digit 'x' in ten's place and 'y' in one's place.
So, The Original Number will be 10x+y and the Reversed Number will be 10y+x.
Now, According to the given information :
⇒ 5(x+y) + 13 = 10x + y
⇒ 4y + 13 = 5x ......(equation 1)
and,
⇒ 4(x+y) + 21 = 10y + x
⇒ 6y - 21 = 3x ......(equation 2)
By solving equation 1 and 2, we get
y = 8 and x = 9
Hence,
The Original Number = 10x + y = 10×9 + 8 = 98
The Reversed number = 10y + x = 10×8 + 9 = 89
and,
The difference of the original two-digit number and the number with reversed digits is ( 98 - 89 ) = 9.
