What are the amplitude, period, and phase shift of the given function?

answer:

1.

step-by-step explanation:

note that 2^4 - 2^3 = 16 - 8 = 8 = 2^3

in a similar way 2^6 - 2^5 = 64 - 32 = 32 = 2^5.

so 2^99 - 2^98 = 2^98 ,   2^98 - 2^97 = 2^97 ,   2^97 - 2^96 = 2^96 and so on.

therefore when we come to the last 2 terms we have 2^1 - 2^0 = 2 - 1

= 1 , so the answer is 1.

answer:

louis needs to save 15+39 = $ 54 dollars

step-by-step explanation:

\begin{aligned} 15 + 39 & =& \\ 10 + 5 + 30 + 9 & =& \\ 10 + 30 + 5 + 9 & =& \\ 40 + 10 + 4 & =& \\ 54. \end{aligned}

so louis needs to save \$54.
