Área- 5(8x +3)
Simplify- 40x +15

Perimeter- 2(8x+3) + 2(5)
Simplify- 16x+6+10
Simplify more- 16x +16

Find the values for m and n that would make the following equation true.

dimaraw [331]

You would solve it in two parts.

4*n = 44 Divide by 4

4n/4 = 44/4

n = 11

=============

z^m * z^2 = z^9

When the bases are the same (on the left) the powers on the left add

m + 2

The powers on the left side of the equation are the same as the powers on the right when the bases are the same.

m + 2 = 9 Subtract 2 from both sides.

m + 2 - 2 = 9 - 2

m = 7

=================

Lui deposited $3,500 into a savings account. The simple interest is 4%. How much interest will the account earn in 2 years?

Varvara68 [4.7K]

Answer:

$280

Step-by-step explanation:

Principal = $3,500

Time = 2 Years

Interest Rate = 4%

Interest = Principal x Time x Interest Rate

Interest = $3,500 x 2 x 0.04

Interest = $280

Investigate the difference between compounding annually and simple interest

Gennadij [26K]

Step-by-step explanation:

Simple interest formula

$A = P (1 + rt)$

Compound interest formula

$A = P(1 + \frac{r}{n})^{nt}$

$A = 5000 (1 + 0.025*1)\\A=5000(1.025)\\A=5125$

Simple interest is $125

. $A = 5000 (1 + \frac{0.025}{1})^{1*1} \\A=5000(1.025)\\A= 5125$

Compound interest is $125

c. the result for both a and b are the same

$A = 5000 (1 + 0.025*3) \\A=5000(1.075) \\A=5375$

the simple interest is $375

. $A = 5000 (1 + \frac{0.025}{1})^{1*3}] \\A=5000(1.025)^3 \\A=5000(1.077)\\A= 5385$

the compound interest is $385

f. the result compared, compound interest is $10 more than simple interest

$A = 5000 (1 + 0.02*6) \\A=5000(1.12) \\A=5600$

the simple interest is $600

$A = 5000 (1 + \frac{0.02}{1})^{1*6}] \\A=5000(1.12)^6 \\A=5000(1.9738) \\A= 9869$

the compound interest is $4869

i. the result from g and h, h is over 8 times bigger than g.

j. interest compound annually is not the same as simple interest, only for the case of a and b seeing that it is for 1 year. but for 2years and above there is difference as seen in c to h
