Answer:

(a). 32 copies

(b). $3060

Step-by-step explanation:

<u>Solution for (a):</u>

<u />

P = 60c + 1800

If P is $3720 then;

3720 = 60c + 1800

60c = 3720 - 1800 = 1920

c = \frac{1920}{60} = 32 copies

<u>Solution for (b):</u>

<u />

P = 60c + 1800

If c is 21 then;

P = $60(21) + $1800

P = $1260 + $1800

P = $3060

poizon [28]
We have the formula tan(a+b)= (tana+tanb): (1-tana x tanb)
And now we have a=80, b=70 and
(tan80+tan70): (1-tan80 x tan70)= tan(80+70)= tan150
If you write 70 for 70°, we have tan150°=1/√3

The point A(-2, 3) is translated using T: (x,y) → (x + 4, y + 2).
kotegsom [21]

The distance between the points A(-2, 3) and A'(2, 5) is 2√5 units if the point A(-2, 3) is translated using T: (x, y) → (x + 4, y + 2).

<h3>What is a distance formula?</h3>

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have a point A(-2, 3)

After applying the translation:

T: (x,y) → (x + 4, y + 2)

A' = (-2+4, 3+2) = (2, 5)

The distance between A and A':

\rm d=\sqrt{(2+2)^2+(5-3)^2}

d = √20

or

d = 2√5 units

Thus, the distance between the points A(-2, 3) and A'(2, 5) is 2√5 units if the point A(-2, 3) is translated using T: (x, y) → (x + 4, y + 2).
