Answer:
Step-by-step explanation:
I don’t know why they bother teaching recursive formulas as the explicit is almost always used :)
For 2,9,16,23...
Recursive is a(n+1)=an+7
Explicit is an=2+7(n-1)
(or more neatly an=7n-5)
For 2,14,98,686...
Recursive is a(n+1)=7an
Explicit is an=2(7^(n-1))
(or (2/7)7^n )

Answer:
A) (56)^−2
Step-by-step explanation:
(22 + 34)^−2
Parentheses first
22+34= 56
56 ^-2
Answer:
See Below
Step-by-step explanation:
To get volume of cuboid, we multiply the 3 dimensions.
<u>Volume of Box</u> = 28 * 15 * 20 = 8400
<u>Volume of 1 disc case</u> = 1.5 * 14.2 * 19 = 404.7
<u>Volume of 17 disc cases</u> = 17 * 404.7 = 6879.9
Since, volume of 17 disc cases is less than volume of the cuboid box, definitely 17 disc cases will fit the box.
For the first one, simplify the radicals. The 3 root 8 can be rewritten as 3 root 4 root 2, which turns into 6 root 2. The 4 root 3 can’t be simplified, so just multiply. 6*4=24 and the root 2*root 3 turns into root 6. So your answer for the first one is 24 root 6.
For the next one you can’t have a radical in the denominator so just multiply by root 3/ root 3, which gives you 6 root 3/3 which simplifies into 2 root 3.
