The number of caps a new online store sells increases by a factor of 4 each month. the function f(x)=4^x represents the number of caps sold in month x. when does the store sell 64 caps? a. month 3 b. month 4 c. month 2 d. month 16

For this case we have the following variables:

x: number of months

f (x): number of caps sold

The function that models the problem is given by:

By the time the store sells 64 caps we have:

From here, we clear the number of months:

the store sells 64 caps in 3 monts

A. month 3

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
