Answer:

7x³y² - 3x²y² + xy - 5

Step-by-step explanation:

Add like terms.

5x³y² + 2x³y² = 7x³y²

-3x²y² = -3x²y²

-3xy + 4xy = xy

2 - 7 = -5

Put them all together.

7x³y² - 3x²y² + xy - 5

Find the future value of an annuity due of $400 each quarter for 4 1 2 years at 13%, compounded quarterly. (Round your answer to
Flura [38]

Answer:

$9891.23


Step-by-step explanation:

The formula for future value of annuity due is:

FV=P[\frac{(1+r)^{n}-1}{r}]*(1+r)

Where,

  • FV is the future value of the annuity (what we need to find)
  • P is the periodic payment (here it is $400)
  • r is the interest rate per period (here 13% yearly interest is actually \frac{13}{4}=3.25 percent per period(quarter))
  • n is the number of periods (here the annuity is for 4\frac{1}{2} years, which is 4\frac{1}{2}*4=18 periods, since quarterly and there are 4 quarters in 1 year)

Substituting all those values in the equation we get:

FV=400[\frac{(1+0.0325)^{18}-1}{0.0325}]*(1+0.0325)\\=400[23.9497]*(1.0325)\\=9891.23

Hence, the future value of the annuity due is $9891.23

Um not fully confident which is funny because imma freshman but i believe you combined all the like terms to get “180 = 23x - 188” and it equals 180 in the end because it’s a straight line so anyways once you solve the problem you should get 16 i believe and if you’re confused just feel free to ask me and i hope i wasn’t too late to answer it

netineya [11]

Answer:

35cm

Step-by-step explanation:

The net of a regular pentagon has 10 sides.

Since each of the faces are equilateral triangles, the side lengths are equal.

Therefore:

Length of each side of the net = 70/10 =7cm

Therefore, the base is a regular pentagon of side length 7cm.

The perimeter of the base of the pyramid = 5 X 7

=35cm

The perimeter of the base of the pyramid is 35cm.
