6 0

Answer:

b. A year and a half

Step-by-step explanation:

First, we can find the total cost

1512+263=1775

Next, we can divide by 50 in order to find out how many months it will take for the panel to pay for itself.

\frac{1775}{50} =35.5 months

This is very close to 36 months, which is <u>A year and a half</u>.

The triangles below are similar. By what ratio was triangle XYZ enlarged by to create triangle LMN? Use this information to calc
aliina [53]

Answer:

Ratio: 3:2

LN = 18

Step-by-step explanation:

"similar" means that all the angles are the same and the sides were all increased by the same proportion.

Thus, we know that MN/YZ = LM/XY = NL/ZX

First, we need to find the ratio. To do this, we write MN/YZ as a fraction, and simplify.

MN/YZ = 15/10 = 3/2

(If you want, you can double check this using LM nd XY. 8 * 3/2 = 12, so this is correct)

To find the missing side, we simply multiply XZ by 3/2.

12 * 3/2 = 18, so LN = 18.

Determine the correct equation of the following graph.
Vladimir [108]

The equation of the given sine graph is gotten as; y = 4 sin [(0.4(x + 2.5)] - 1

<h3>How to find the equation of a sine graph?</h3>

We know that the  general formula for equation of a sine graph is;

y = A sin [(B(x - D)] + C

where;

A is Amplitude

Period = 2π/B.

Phase Shift = -C/B.

Vertical Shift = D.

From the graph;

A = 4

B = 2π/5π = 2/5

C = -1

D = -5/2

Thus;

y = 4 sin [(0.4(x + 2.5)] - 1
