Answer:
2628.48 cubic inches
Step-by-step explanation:
The inflatable raft has 4500 cubic inches of air inside it when fully inflated.
The inflatable raft loses air at a rate of a decrease 6.5% each day.
Now, we have to calculate the volume of air that will be left in the raft after 8 days.
Therefore, the volume of air left in the raft after 8 days will be ![4500[1-\frac{6.5}{100} ]^{8} =2628.48](https://tex.z-dn.net/?f=4500%5B1-%5Cfrac%7B6.5%7D%7B100%7D%20%5D%5E%7B8%7D%20%3D2628.48)
cubic inches. (Answer)
1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74
2,11,26,47,74
Answer C. 2,11,26,47,74.
Answer:
x = 15
Step-by-step explanation:
4x is congruent to 45 + 15
4x = 45 + 15
simplify 4x = 60
divide both sides by 4 x = 15
