Answer:
Step-by-step explanation:
area=4×22/7×14²=4×22×28=2464 units²
Answer:
1250
Step-by-step explanation:
30,000/24
divide both sides by 24 to get 1250.
13. Let A = the amount of money in the given time, P = principal amount; the amount of money you start with, T = time in years, R = interest rate, and N = amount of times interest is compounded each year.
The formula for compound interest is:

Now, we find in the information from the description needed to plug in. P = $1000, R = 7% or 0.07, N = 1 time a year, T = 3 years

This simplifies to:

And again to:

Plug this into a calculator:
A = 1225.043 or ≈1,225.04
14. (x² + 3)(x - 3)(x + 3)
I'm going to do FOIL method on the second and third binomials first and simplify. This gives you:
(x² + 3)(x² - 9)
Then you do the FOIL method again to get:
x⁴ - 9x² + 3x² - 27
And combine like terms for your answer:
x⁴ - 6x² - 27
Number 15 doesn't give you a number to set the polynomial (that results from multiplying those two binomials) equal to so I'm guessing it wants you to set said polynomial equal to zero and solve for x then plug back in.
If not, your area is found by the equation 3x² - 5x - 12
4+(−7) is 7 units from 4, in the negative direction (that is, to the left of 4)
The terms of an arithmetic progression, can form consecutive terms of a geometric progression.
- The common ratio is:

- The general term of the GP is:

The nth term of an AP is:

So, the <em>2nd, 6th and 8th terms </em>of the AP are:



The <em>first, second and third terms </em>of the GP would be:



The common ratio (r) is calculated as:

This gives

The nth term of a GP is calculated using:

So, we have:
