What is the monomial if a square of a monomial is: 0.0001*a^8*x^4

Georgia [21]

Answer:

Monomial $0.0001\cdot a^8\cdot x^4$ is a square of monomial $0.01\cdot a^4\cdot x^2$

Step-by-step explanation:

Given monomial $0.0001\cdot a^8\cdot x^4$

Using property $(a^m)^n=a^{m\cdot n},$ note that

$0.0001=(0.01)^2\\ \\a^8=(a^4)^2\\ \\x^4=(x^2)^2$

So,

$0.0001\cdot a^8\cdot x^4=(0.01)^2\cdot (a^4)^2\cdot (x^2)^2.$

Now use property $(a\cdot b)^n=a^n\cdot b^n$ to rewrite the previous expression:

$(0.01)^2\cdot (a^4)^2\cdot (x^2)^2=(0.01\cdot a^4\cdot x^2)^2$

Hence, monomial $0.0001\cdot a^8\cdot x^4$ is a square of monomial $0.01\cdot a^4\cdot x^2$

Samantha puts an initial $500 into a savings account. The account has a 4% annual compound interest rate. What is the function t

Licemer1 [7]

I use a bit of a different looking formula.

A(t)=P(1+r/n)^nt

P=amount of money. (500)
r= rate (in decimal. 4%=0.04)
n=number of times per year (1 in this problem)
t=amount of time. (5 years)

Plugged in it looks like this:

A(t)=500 (1+ 0.04/1)^1x5

Then I put it into my calculator like this:

0.04/1+ 0.04

Then add one to the above answer:

0.04+1=1.04

Then raise the above answer to the 1x5:

1.04^5=1.2166......

Then multiply the above answer by 500:

1.2166.... x 500=608.3264512

She has $608 after 5 years.

Hope this helps, let me know if you have any questions.
