## anonymous one year ago WHAT EVER U WANT ILL GIVE NEED HELP Samantha puts an initial \$500 into a savings account. The account has a 4% annual compound interest rate. What is the function that best represents Samantha's account and how much does she have in savings after 5 years? Round your answer to the nearest dollar. Hint: Use the formula, f(x) = P(1 + r)x. f(x) = 500(1.4)x, \$2,689 f(x) = 500(0.04)x, \$512 f(x) = 500(1.04)x, \$608 f(x) = 500(1.04)x, \$527

In the formula: r is the rate, P is the initial amount, x is the number of years so just plug in 0.04 for r and 500 for P. f(x) = 500(1.04)^x plug in 5 for x \$608 phew

The sides of a square are three to the power of two sevenths inches long. What is the area of the square? nine to the power of four sevenths square inches three to the power of four sevenths square inches three to the power of the fraction four over forty nine square inches nine to the power of the fraction four over forty nine square inches

9. anonymous

3^(2/7) ? or (3^2)/7?

SORRY I ALMOST DOSED OFF WAIT A SECOND

14. anonymous

ok ok um if the bases are the same you can add powers think of it as 3^(2/7) * 3^(2/7)

15. anonymous

so yeah 3^(2/7 + 2/7) is the answer

16. anonymous

these are the answers nine to the power of four sevenths square inches three to the power of four sevenths square inches three to the power of the fraction four over forty nine square inches nine to the power of the fraction four over forty nine square inches

B

19. anonymous

yeah

20. anonymous

:D teddy bear

21. anonymous

btw realize you can just plug it in the calculator or even google and see which ones match

OMG SO SRY ONE MORE PLEASE Given the function f(x) = 2(3)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average rate of change of each section. (4 points) Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points)

27. anonymous

wait is this physics???

28. anonymous

Idk im in 8th but i take 9 and 10th grade math

29. anonymous

wait are there any powers in the equation?

30. anonymous

no

31. anonymous

I'm so confused do you have screenshot?

32. anonymous

33. anonymous

oh x is a power of 3

34. anonymous

you meant 2(3)^x

35. anonymous

partA: sectionA: 6-2=4 sectionB: 54-18=36 part B: 36/4 = 9 9 times greater

36. anonymous

yeah you just had to plug in each number for x than find the difference

37. anonymous

Thanks jaredhm29 that was great algebra review (not being sarcastic) :D

THANK U SO MUCH U WERE SOOOOOOO HELPFUL
