I don't know about the first one but the second one is 34.9°. It would be that because are right angles add up to 90° and if you subract 55.1 and 90 it would equal 34.9. But this rule only works on right angles.

The area of a square is represented by the expression 16x^4y^8. What is the length of each side of this square

Leona [35]

Answer: $4x^2y^4$

Step-by-step explanation:

Given

The area of the square is $A=16x^4y^8$

Suppose a is the side length of the square

The area of the square is given by

$\Rightarrow A=(\text{side length})^2$

So, we can write

$\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4$

length of each side is $4x^2y^4$

I need help please if m<MNR=43 and m<MNP=84 find: m<RNP subtract or add

Zielflug [23.3K]

Answer:

41°

Step-by-step explanation:

The angle addition theorem tells you ...

m∠MNR + m∠RNP = m∠MNP

Filling in the given values, you have ...

43° + m∠RNP = 84°

Subtract 43° from both sides of the equation to find the angle of interest:

m∠RNP = 84° - 43° = 41°

The measure of angle RNP is 41°.

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

zaharov [31]

After 6 years the investment is $5555.88

Step-by-step explanation:

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

The formula used to find future value is:

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

where A(t) = Accumulated amount

P = Principal Amount

r = annual rate

t= time

n= compounding periods per year

We are given:

P = $3600

r = 7.5 %

t = 6

n = 1

Putting values in formula:

$A(t)=P(1+\frac{r}{n})^{nt}\\A(t)=3600(1+\frac{0.075}{1})^{6*1}\\A(t)=3600(\frac{1.075}{1})^6\\A(t)=3600(1.075)^6\\A(t)=3600(1.543)\\A(t)=5555.88$

So, After 6 years the investment is $5555.88
