Answer:
Pretty much f(n)=-3+5n-1
Step-by-step explanation:
for the 50th term 242
Answer:
(5x-1)(3x+2)
(if you don't want to do all of this you can use
Step-by-step explanation:
((3•5x2) + 7x) - 2
Factoring 15x2+7x-2
The first term is, 15x2 its coefficient is 15 .
The middle term is, +7x its coefficient is 7 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 15 • -2 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 7 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 10
15x2 - 3x + 10x - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (5x-1)
Add up the last 2 terms, pulling out common factors :
2 • (5x-1)
Step-5 : Add up the four terms of step 4 :
(3x+2) • (5x-1)
Which is the desired factorization
Answer:
81
Step-by-step explanation:
9 x 9 = 81
So, 81 is the perfect square.
The answers to the questions are:
- a. $33,750
- b. $36000
- c. $90000
a. <u>the straight-line method of depreciation</u>
= (240000 - 60000) / 4 * (9 / 12)
= $33,750
The debit is 33750 as well as the credit
b. <u> the units-of-production method of depreciation</u>
(240000 - 60000) / 60000 * 12000
= $36000
c. <u>the double-declining balance method of depreciation</u>
(24000 *2 /4) * (9/12)
= $90000
