5³*5^6=5^9
8^7/8²=8^5
9^7/9^11=1/9²
4^5^3=4^15

when multiplying like bases you add exponents. when dividing like bases you subtract exponents. when reasoning a number to a power then to another power you multiply exponents

Solar panels installed in a backyard have a cross section that is a right triangle. The diagram shows the approximate dimensions

Citrus2011 [14]

Answer:

About 4.2 ft

Explanation:

The area of the traingle can be calculated in two ways.

$A=\frac{1}{2}\text{width}\cdot\text{length}$

where width = 4.4 ft and length = 13.6 ft.

Putting in the values for width and length gives

$\begin{gathered} A=\frac{1}{2}13.6\cdot4.4_{} \\ \boxed{A=29.92ft^2} \end{gathered}$

The other way that the area can be calculated is

$A=\frac{1}{2}\cdot\text{height}\cdot\text{base}$

where height = vertical length and base = 14.3 ft; therefore.

$\begin{gathered} A=\frac{1}{2}14.3h \\ A=7.15h \end{gathered}$

This must equal the area of the triangle we found above; therefore,

$A=29.92=7.15h$ $29.92=7.15h$

dividing both sides by 7.15 gives

$h=\frac{29.92}{7.15}$ $\boxed{h\approx4.2ft}$

which is our answer!

Write two equations for a horizontal line and a vertical line.

wlad13 [49]

Two equations for a horizontal line could be y = 1 & y = 5
Two equations for a vertical line could be x = 2 & x = 6

Horizontal lines are created when y is always equal to one number, while vertical lines are created when x is always equal to one number.

Hope this helps!
