Answer:

Step-by-step explanation: The surface area is the area of the rectangular base (length width) plus the areas of each of the four triangular faces. The area of a triangle is 1/2 base height so all that remains is to find the height of each of the triangular faces.

Use these complex numbers from the table to write the following expression as a complex number in standard form.

xxTIMURxx [149]

Answer:

= 5 − 101i

Step-by-step explanation:

2i(A ∙ E) − C + G

2i(-3 − 4i)(8 − 8i) − (13 + i) + (2 + 12i)

2i(-24 + 24i − 32i + 32i2) − (13 + i) + (2 + 12i)

2i(-24 − 8i − 32) − (13 + i) + (2 + 12i)

2i(-56 − 8i) − (13 + i) + (2 + 12i)

(-112i − 16i2) − (13 + i) + (2 + 12i)

(16 − 112i) − (13 + i) + (2 + 12i)

(16 − 112i) + (-13 − i) + (2 + 12i)

(16 − 13 + 2) + (-112i − i + 12i)

(16 − 13 + 2) + (-112 − 1 + 12)i

= 5 − 101i

A semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.

Novay_Z [31]

Answer:

Graph A is the correct choice.

Step-by-step explanation:

Let x be the number of weeks.

We have been given that a semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.

Let us find the weekly salary for 1000 employees by multiplying 1000 by $750.

$\text{The weekly salary for 1,000 employees}=1,000\times \$750$

$\text{The weekly salary for 1,000 employees}=\$750,000$

Let us find amount of salaries after 52 weeks as 1 year equals 52 weeks.

$\text{The amount of salaries after 52 weeks for 1,000 employees}=52*\$750,000$

$\text{The amount of salaries after 52 weeks for 1,000 employees}=\$39000000$

Since at week 0, the salaries for 1000 employees will be also 0, so point (0,0) will be on the line of our graph.

Now let see which of our given graphs has point (0,0) and (52,39000000).

We can see that graph A has y-value 39 million on x equals 52, therefore, Graph A is the correct choice.
