1 Identify whether the series summation of 16 open parentheses 5 close parentheses to the I minus 1 power from 1 to infinity is a convergent or divergent geometric series and find the sum, if possible.A This is a convergent geometric series. The sum cannot be found. (I think this)

B This is a divergent geometric series. The sum cannot be found.

C This is a convergent geometric series. The sum is –4.

D This is a divergent geometric series. The sum is –4.

Answers

Answer 1

Answer: sum to infinite for
1) arithmetic series is always divergent, sum is infinite.
2) geometric series is convergent if -1 < common ratio < 1 otherwise it is divergent.

b) is correct , (r = 5) > 1

Ralph jordan recently bought a new lawnmower for 228.00. If he had to pay 6% sales tax on the lawnmower, what wasthe total cost of the lawnmower?A:$251.62
B: 234.00
C:241.68
D:312.42

Answers

First we find what 6% of 228.00 is.

To do that we would multiply the number by the percent
So 228 x 6 = 1368
Then divide the answer by 100.
1368/100 = 13.68

You can round if you would like but in this case I believe we should leave it alone.

Which means the price was 228.00 and the tax was 13.68 we just have to add them together to find the answer.

228.00 + 13.68 = 241.68

The answer would be C.

85% of what number equals 17

Answers

percent means parts out of 100
85%=85/100=0.85
'of' means multiply

therefor
85% of x equals 17 means
0.85 times x=17
divide both sides by 0.85
x=20

the number is 20

Four times a number, x, plus five times a number, y, equals 79. Ten times x minus 5 times y equals 5. Find the numbers by setting up a system of linear equations and solving the system using the elimination method.a) x = 7, y = 9
b) x = 6, y = 11
c) x = 8, y = 10
d) x = -10, y = 7

Answers

the correct answer is X=6 & Y=11

15x+12=45+4x
whats x?

Answers

15x+12=45+4x ⇒15x - 4x = 45 - 12 ⇒ 11x = 33 ⇒ x = 3

Like terms are when the variable you have are the same. In this case it is x. Therefore, when you have like terms, you should add, or subtract your like terms.

(note: When you move one thing to the other side of the equation, make sure to do the opposite of the sign. i.e. if it is +4 when you move to the other side it will be -4).

15x+12=45+4x
15x+12-12=45+4x-12
15x=45+4x-12
15x-4x=45+4x-4x-12
15x-4x=45-12
11x = 33
this is the same as:
11*x = 33
the opposite of multiply is divide so when we move the 11 it has to be divide
11/11*x=33/11
x=3
