Answer: The actual length of a room that measures 2.8 inches on the blueprint will be 22.4 feet.

Step-by-step explanation:

We are given that ,

On a set of blueprints, the scale is \dfrac{1}{2}\text{inch= 4 feet}

Multiply 2 both sides , we get

Then, \text{1 inch = }2\times4=8\text{ feet}

\Rightarrow\ \text{2.8 inch = }2.8\times 8\text{ feet}

\Rightarrow\ \text{2.8 inch = }22.4\text{ feet}

Then, the actual length of a room that measures 2.8 inches on the blueprint.  will be 22.4 feet.

Hence, the correct answer is 22.4 feet.

Write the sum using summation notation, assuming the suggested pattern continues. 5 - 15 + 45 - 135 + ...
nalin [4]

Answer:

<em>summation of five times negative three to the power of n from n equals zero to infinity</em>

Step-by-step explanation:

<u>Summation Notation </u>

It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:

5-15+45-135+...

If we take 5 as a common factor, we have

5(1-3+9-27+...)

The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1

The summation is then represented by

\sum_{n=0}^{\infty}5(-3)^n

This corresponds with the option:

<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
