Question

Medal for best answer



Because of the rainy season, the depth in a pond increases 3% each week. Before the rainy season started, the pond was 10 feet deep. What is the function that best represents the depth of the pond each week and how deep is the pond after 8 weeks? Round your answer to the nearest foot.


Hint: Use the formula, f(x) = P(1 + r)x. (5 points)


f(x) = 10(0.03)x, 36 feet

f(x) = 10(1.03)x, 14 feet

f(x) = 10(1.3)x, 37 feet

f(x) = 10(1.03)x, 13 feet

Answer 1

Hello

Answer 2

last option is correct f(x) = 10(1.03)x where x is the number of time intervals that have passed r is growth rate,since r is given in percentage so we will divide 3 by 100 you can solve it like this
f(x)=10(1+0.03)8

Answer 3

Okay can u help me with one more?

Answer 4

x should be the power of term (1+r)

Answer 5

and yes

Answer 6

Answer 7

ok

Answer 8

Im pretty sure its the 2nd answer but want to make sure

Answer 9

an example of
The product of a non-zero rational, and a irrational number, begin equal to an irrational "

2 x √3 = 2√3

C is not FALSE

Answer 10

Okay so the answer is the 2nd one?

Answer 11

A. is the answer and is false

proof 5 x 5 =25 Both 5s are rational and so is 25

√4 x √4 = √16 = 4 All are rational.

Answer 12

so the first any more
