Initially, there were only 197 weeds at a park. the weeds grew at a rate of 25% each week. the following function represents the weekly weed growth: f(x) = 197(1.25)x. rewrite the function to show how quickly the weeds grow each day and calculate this rate as a percentage.
a.) f(x) = 197(1.25)^7x; grows at a rate of approximately 2.5% daily
b.) f(x) = 197(1.25^7)^x; grows at a rate of approximately 4.77% daily
c.) f(x) = 197(1.03)^x; grows at a rate of approximately 0.3% daily
d.) f(x) = 197(1.03)^7x; grows at a rate of approximately 3% daily

  D.)  f(x) = 197(1.03)^(7x); grows at a rate of approximately 3% daily

Step-by-step explanation:

The growth equation can be written in terms of a rate compounded 7 times per week:

  f(x) = 197×1.25^x = 197×(1.25^(1/7))^(7x)

  f(x) ≈ 197×1.0324^(7x) . . . . x represents weeks, a daily growth factor is shown

The daily growth rate as a percentage is the difference between the daily growth factor and 1, expressed as a percentage:

  (1.0324 -1) × 100% = 3.24%

The best match is choice D:

  f(x) ≈ 197(1.03^(7x)); grows approximately 3% daily

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
