Step-by-step explanation:

1

\frac{1}{3 + 4i}  \times  \frac{3 - 4i}{3 - 4i}  =  \frac{3 - 4i}{25}  =  \frac{ 3}{25} -  \frac{4i}{25}

2)

\frac{1}{3  -  4i}  \times  \frac{3  + 4i}{3  + 4i}  =  \frac{3  + 4i}{25}  =  \frac{ 3}{25}  + \frac{4i}{25}

3)

1+0i

4)

\frac{3 - 4i}{3 + 4i}  \times  \frac{3 - 4i}{3 - 4i}  =  \frac{ - 7 - 24i}{25}  =  -  \frac{7}{25}  -  \frac{24i}{25}

5)

3 - 4i

6)

\frac{3 + 4i}{3 - 4i}  \times  \frac{3 + 4i}{3 + 4i}  =  \frac{ - 7 + 24i}{25}  =  -  \frac{7}{25}  +  \frac{24i}{25}

A 50-ft x 300-ft parking lot is divided into sections for a craft fair by bisecting the width and the length. Each half is again
lina2011 [118]

Answer:

The dimensions of each section will be 12.5 ft by 75 ft.

The area of each section will be 937.5 sq. ft.

Step-by-step explanation:

A parking lot with dimensions 50 ft. by 300 ft. is divided into sections by bisecting the width and the length.

So, each half will have dimensions 25 ft by 150 ft.

Each half is again bisected in length and width.

So, the dimensions of each section will be 12.5 ft by 75 ft.

Now, the area of each section will be (12.5 × 75) = 937.5 sq. ft. (Answer)

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic
alexgriva [62]
Each multiple choice question would be 5 points. For Louann she got 14 of the questions correct so 5 x 14 = 70 and 70 + 24 would be 94. For Carla she got 16 of the questions correct so 5 x 16 = 80 and 80 + 14 = 94. You're answer would be 5, hopefully this helps :)

If f(x)= (3x+7)^2, then f(1) = ?
Crank
To find f(1), substitute 1 for x.

f(1) = (3(1)+7)²
f(1) = (3+7)²
f(1) = 10²
f(1) = 100
