Answer:
Simplifying 9m + -3 + -7m = 0
Reorder the terms: -3 + 9m + -7m = 0
Combine like terms: 9m + -7m = 2m -3 + 2m = 0 Solving -3 + 2m = 0
Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right.
Add '3' to each side of the equation. -3 + 3 + 2m = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2m = 0 + 3 2m = 0 + 3 Combine like terms: 0 + 3 = 3 2m = 3
Divide each side by '2'. m = 1.5

Use the shell method. Each shell has a height of 3 - 3/4 <em>y</em> ², radius <em>y</em>, and thickness ∆<em>y</em>, thus contributing an area of 2<em>π</em> <em>y</em> (3 - 3/4 <em>y</em> ²). The total volume of the solid is going to be the sum of infinitely many such shells with 0 ≤ <em>y</em> ≤ 2, thus given by the integral
Or use the disk method. (In the attachment, assume the height is very small.) Each disk has a radius of √(4/3 <em>x</em>), thus contributing an area of <em>π</em> (√(4/3 <em>x</em>))² = 4<em>π</em>/3 <em>x</em>. The total volume of the solid is the sum of infinitely many such disks with 0 ≤ <em>x</em> ≤ 3, or by the integral
Using either method, the volume is 6<em>π</em> ≈ 18,85. I do not know why your textbook gives a solution of 90,43. Perhaps I've misunderstood what it is you're supposed to calculate? On the other hand, textbooks are known to have typographical errors from time to time...

f=7x g=3 x=18
Step-by-step explanation:
The discount factor computed shows that the value of each payment will be $1546.
<h3>How to calculate the payment?</h3>
The following can be deduced from the information:
Payment due in 5 months = $1684
Payment due in 8 months = $1323
Annual interest = 11.40%
Monthly interest rate = 11.40%/12 = 0.95%
Present value of payment due 5 months ago = $1684 + (1 + 0.95%)⁵ = $1765.52
Present value of payment due 8 months ago = $1226.62
Total present value = $1765.52 + $1226.62 = $2992.14
After rescheduling, the payments will be in 2 months and 5 months.
Discount factor for payment due in 2 months = 0.9813
Discount factor for payment due in 5 months = 0.9538
Combined discount factors= 0.9360
Therefore, the value of each payment will be:
= $2992.14/(1 + 0.9360)
= $1546
