Let p (n) be the statement that a postage of n cents can be formed using just 4-cent stamps and 7-cent stamps. the parts of this exercise outline a strong induction proof that p(n) is true for n 18.
a) show statements p (18), h19), h20), and f(21) are true, completing the basis step of the proof.
b) what is the inductive hypothesis of the proof?
c) what do you need to prove in the inductive step?
d) complete the inductive step for k 21.
e) explain why these steps show that this statement is true whenever n 18.

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

step-by-step explanation:

6

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
