Answer:

She would pay <u>$38.17</u>.

The correct answer is B.) 38.17

Step-by-step explanation:

Given:

Sam's Discount Store offers a 2% discount for paying cash.

A set of skillets priced at $38.95.

Now, to find the amount Joan would pay cash for a set of skillets.

Cost price of skillets = $38.95.

Discount rate = 2%.

Now, to get the price after discount:

38.95-2\%\ of\ 38.95\\\\=38.95-\frac{2}{100}\times 38.95\\\\=38.95-0.02\times 38.95\\\\=38.95-0.78\\\\=38.17.

Therefore, she would pay $38.17.

The correct answer is B.) 38.17

Evaluate the summation of 3 n plus 2, from n equals 1 to 14. 39 49 340 343.
lord [1]

The summation of the considered expression in terms of n from n = 1 to 14 is given by: Option D: 343

<h3>How to find the sum of consecutive integers?</h3>

1 + 2 + 3 + ... + n = \dfrac{n(n+1)}{2}

<h3>
What are the properties of summation?</h3>

\sum_{i=r}^s  (a \times f(i) + b) = a \times [\: \sum_{i=r}^s f(i)] + (s-r)b

where a, b, r, and s are constants, f(i) is function of i, i ranging from r to s (integral assuming).

For the given case, the considered summation can be written symbolically as:

\sum_{n=1}^{14}  (3n + 2)

It is evaluated as;

\sum_{n=1}^{14}  (3n + 2) = 3 \times [ \: \sum_{n=1}^{14} n ] + \sum_{n=1}^{14} 2\\\\\sum_{n=1}^{14}  (3n + 2) = 3 \times \dfrac{(14)(14 + 1)}{2} + (2 + 2 + .. + 2(\text{14 times}))\\\\\sum_{n=1}^{14}  (3n + 2) = 3 \times 105 + 28 = 343\\

Thus, the summation of the considered expression in terms of n from n = 1 to 14 is given by: Option D: 343

What is the radical form of each of the given expressions?
earnstyle [38]

Answer:

6^{\frac{1}{5} }=\sqrt[5]{6}

6^{\frac{7}{5} }=\sqrt[5]{6^7}

6^{\frac{1}{6} }=\sqrt[6]{6}

7^{\frac{1}{2} }=\sqrt[2]{7}

7^{\frac{5}{2} }=\sqrt[2]{7^5}

6^{\frac{9}{2} }=\sqrt[2]{6^9}

Step-by-step explanation:

A radical is the root operation for n roots such as square root or cuberoot in the form \sqrt[n]{x}. A fraction exponent x^{m/n} can be converted to the radical form.

6^{\frac{1}{5} }=\sqrt[5]{6}

6^{\frac{7}{5} }=\sqrt[5]{6^7}

6^{\frac{1}{6} }=\sqrt[6]{6}

7^{\frac{1}{2} }=\sqrt[2]{7}

7^{\frac{5}{2} }=\sqrt[2]{7^5}

6^{\frac{9}{2} }=\sqrt[2]{6^9}

Simplify. (-2)^-3<br> A.-8<br> B.-1/8<br> C.1/8<br> D.8
DiKsa [7]

ANSWER

{( - 2)}^{ - 3} =- \frac{1}{ 8}

EXPLANATION

We want to simplify;

{( - 2)}^{ - 3}

Recall that,

{a}^{ - m}  =  \frac{1}{ {a}^{m} }

{( - 2)}^{ - 3}  =  \frac{1}{{( - 2)}^{ 3}}

We multiply out to get,

{( - 2)}^{ - 3}  = \frac{1}{{- 2} \times  - 2 \times  - 2}

{( - 2)}^{ - 3}  =  \frac{1}{ - 8}

The correct choice is B.
