The answer for this problem i −10x2+66xy−36y2−5x+3y

Let's solve it by step by step.

(−5x+3y)(2x−12y+1)

=(−5x+3y)(2x+−12y+1)

=(−5x)(2x)+(−5x)(−12y)+(−5x)(1)+(3y)(2x)+(3y)(−12y)+(3y)(1)

=−10x2+60xy−5x+6xy−36y2+3y

So, -10x2+66xy-36y2-5x+3y

Answer:

Step-by-step explanation:

11) First write in decreasing exponential terms and fill in blanks with zeros.

Our goal is to eliminate all term in the dividend by subtraction

________________

2v - 2 | 2v³ - 16v² + 0v + 13

we see that 2v needs to be multiplied by 1v² to eliminate the first term

v²

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v²

multiply your estimate by your divisor and subtract from the dividend.

bring down the next term and repeat.

v² -7v

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v

repeat again

v² - 7v - 7

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v + 13

-(-14v + 14)

-1

and remainder gets put over the divisor and appended

v² - 7v - 7 - 1/(2v - 2)

13) Same process

5a + 1 | 40a³ - 12a² - 39a - 5

8a²

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

8a² - 4a

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(-20a² - 4a)

-35a - 5

8a² - 4a - 7

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(20a² - 4a)

-35a - 5

-(-35a - 7)

8a² - 4a - 7 + 2/(5a + 1)

You worked as a lifeguard this summer and earned an extra $3,000. You decided to deposit that amount into your savings account.

Nataly [62]

Answer:

The correct answer is $3300 for simple interest and $3312.24 for compound interest.

Step-by-step explanation:

Income as working as a lifeguard = $3000

We deposit the money in a bank which offers 2% interest annually for a period of 5 years.

Case 1 : Calculating simple interest for the given situation.

Amount after 5 years = 3000 + 3000 × 2 × 5 × $\frac{1}{100}$ = $ ( 3000 + 300) = $3300.

Case 2 : Calculating compound interest for the given situation.

Amount after 5 years = 3000 × $(1 + \frac{2}{100} ) ^{5}$ = $ 3312.24.

Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24
