For this case we have the following expression:

$58- (14) ^ 2$

The first step is to solve the quadratic term.

We have then:

$58- (14) ^ 2 = 58-196$

Then, the second step is to subtract both resulting numbers:

$58- (14) ^ 2 = -138$

We observe that the result obtained is a negative number.

Answer:

The result of the expression is given by:

$58- (14) ^ 2 = -138$

Rewrite in simplest radical form x 5/6 x 1/6

Natasha_Volkova [10]

Answer:

$x^{\frac{5}{6}}/x^{\frac{1}{6}} = \sqrt[3]{x^2}$

Step-by-step explanation:

Given

$x^{\frac{5}{6}}/x^{\frac{1}{6}}$

Required

Rewrite in simplest radical form

Using laws of indices:

$a^m/a^n = a^{m-n}$

This implies that

$x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{5}{6} - \frac{1}{6}}$

Solve Exponents

$x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{5 - 1}{6} }$

$x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{4}{6} }$

Simplify exponent to lowest fraction

$x^{\frac{5}{6}}/x^{\frac{1}{6}} = x^{\frac{2}{3} }$

Using laws of indices:

$a^{\frac{m}{n}} = \sqrt[n]{a^m}$

This implies that

$x^{\frac{5}{6}}/x^{\frac{1}{6}} = \sqrt[3]{x^2}$

This is as far as the expression can be simplified

The function y=7500(1.08)t represents the value y of an investment after t years. What is the value of the investment after 6 ye

boyakko [2]

Answer:

The answer is 48600, but I'm not entirely sure if it correct.

From what I know, if I were to see ¨y=7500(1.08)t¨, we could have to substitute the t with the number of years. Looking like this, ¨y=7500(1.08) x 6¨.

The reason I don know if my answer is correct or not since I don know if you have the t next to 1.08 to represent that or to simply multiply the property of it with 6 (the number of years).

So I tried...

Your Mutual Fund was valued at $237,500. It has lost 6% per year for the last 3 years. What is its value today?

Makovka662 [10]

Answer:

The answer is C) $197,263.70

Step-by-step explanation:

It's losing 6% PER year for the last 3 year.

You can do what I did and take $237,500 and times it 0.06. Which should give you 14,250, that is how much is lost in year one.

So subtract 14,250 from 237,500, you should have $223,250 now.

Repeat the first step with $223,250 now, you times it by 0.06 again and you should get 13,395, you subtract that from $223,250.

You have $209,855 now, once again times that by 0.06 and you get 12,591.30. Subtract 12,591.30 from 209,855 and you should end up with $197,263.70

It's a long, simple method and I'm sure there is another method of solving this question, but this is an easy way to get the answer.
