(4u^3+6u^2+7)+(6u^3-2u+7)
Simplify the sum'

Answers

Answer 1

Answer:

Hi Nova

(4u³+6u²+7)+(6u³-2u+7)

= 4u³+6u²+7+6u³-2u+7

Combine like terms

( 4u³+6u³)+(6u²)+(-2u)+(7+7)

= 10u³+6u² -2u+14

There no like terms so you can not simplify the sum

I hope that's help and if you have questions please ask !

10 POINTS. 1/7 written as a decimal is 0.142857 (this sequence repeats). What digit occurs in the 2012th spot after the decimal? Please explain.

Answers

1/7 = 0.142857142857142857142857142857142857142857142857142857 and so on

the pattern repeats

the first digit is 1
second digit is 4
third digit is 2
fourth digit is 8
fifth digit is 5
sixth digit is 7

and then the seventh digit is 1, and it repeats

so the six digits repeat again and again...

2012/6 = 335 2/6

It has a remainder of 2, which means that the 12th digit will be 4. because that is the second digit. After going 335 times the 6 digit patterns it will stop at the second digit which is 4.

Your answer is 4.

I hope you understood, it was kind of hard to explain :P

Clare made $160 babysitting last summer. She put the money in a savings account that pays 3% interest per year. If Clare doesn't touch the money in her account, she can find the amount she'll have the next year by multiplying her current amount by 1.03. How much will she have in 30 years

Answers

Answer:

$388.36

Step-by-step explanation:

let us assume that the amount in her accounts compounds annually

Given data

principal p= $160

interest rate r= 3%= 0.03

time t= 30 years

At the end of 30 years the money she will will have can be expressed as

A= P(1+r)^t

A= 160(1+0.03)^30

A= 160(1.03)^30

A= 160*2.42726

A= $388.36

in 30 years she will have $388.36

Calculate the monthly finance charge if the average daily balance is $20, the daily periodic rate is 0.05%, and the number of days in the cycle is 30.a) 30 cents.
b) 31 cents.
c) 50 cents.

Answers

To solve the problem above, we must first find the daily finance charge and multiply it by 30, for the number of days in the month cycle is 30. 0.05% or 0.0005 times $20 is $ 0.01, or 1 cent. Multiply that by 30 to get the monthly finance charge which is, 0.01 x 30 = $ 0.30 or 30 cents. The Answer is A. 30 cents.

Answer:

30 cents

Step-by-step explanation:

To calculate the remaining balance we must calculate how much money must be paid per day. We can determine this using the average daily rate of 0.05% and the daily balance. Then we can multiply this with the amount of days in the cycle.

$=20*0.0005*30=0.3$
