\huge\boxed{c=3.5a}

First, we need to find how much a single pound of apples costs.

Do this by dividing.

\frac{\$7}{2\ \text{lbs.}}\div\frac{2}{2}=\frac{\$(7\div 2)}{(2\div 2)\ \text{lbs.}} = \frac{\boxed{\$3.50}}{1\ \text{lb.}}

Now, write an equation.

\large\boxed{c=3.5a}

This represents that the cost equals 3.5 times the number of apples.

Answer:

3.5a=c

Step-by-step explanation:

You can do this in two ways:

Way ONE:

In this scenario:

a=2

c=7

If you plug those numbers into the equation, you get:

3.5*2=7

This statement is correct.

Way TWO:

$7/2=3.50. This is the cost PER POUND OF APPLE.

That means:

<u>Every pound of apple, a, times 3.50, will give you your cost.</u> This is basically just reversing 7/2=3.50, our first statement.

In equation form, the underlined statement would look like this:

a*3.5=7, or our answer:

3.5a=7

Answer:

A 2√2(cos 7π/4 + i sin 7π/4)

Step-by-step explanation:

A. 2√2(cos 7π/4 + i sin 7π/4)

2 sqrt(2) ( sqrt(2)/2 - sqrt(2)/2 i)

Distribute

  2-2i

This is in the fourth quadrant  

B. 2√2(cos 150° + i sin 150°)

2 sqrt(2) (-sqrt(3)/2 +1/2i)

-sqrt(6) +sqrt(2) i

This is in the third quadrant (NO)

C. 2(cos 7π/4 + i sin 7π/4)

2( ( sqrt(2)/2 - sqrt(2)/2 i))

sqrt(2) - sqrt(2) i

This is the fourth quadrant

D. 2(cos 90° + i sin 90°)

2(0+i)

2i

This is on the positive y axis  NO

Now we need to decide between the two in the fourth quadrant.

The point has an x coordinate of 2 and a y coordinate of -2

This aligns with point A
