Answer:

96 cm²

Step-by-step explanation:

The surface area of a pyramid is the sum of the base area and the area of the four triangular faces. Using the formulas for each of these, a simplified formula can be written.

A = s(s +2h)

where s is the side length of the square base, and h is the slant height of a triangular face.

For the given dimensions, s=4 cm, h=10 cm, the surface area is ...

A = (4 cm)(4 cm +2×10 cm) = (4)(24) cm²

A = 96 cm²

The surface area of the pyramid is 96 square centimeters.

Let x be the distance of the additional water stations from the starting line.
We want on that is 1.5 miles behind the 8-mile water station, and one that is 1.5 miles ahead. The following absolute value function describes x:
|x-1.5| = 8
Two numbers comply: x= 9.5 and 6.5.
The additional water stations will be 6.5 and 9.5 miles from the starting line.

Answer:

$\frac{1}{a^{6} b^{4} }\\\frac{a^{6} }{b^{6} }\\ \frac{a^{6} }{b^{5} } \\\frac{b^{6} }{a^{6} }\\ a^{6} b^{3}$

Step-by-step explanation:

Basically when a variable with a negative exponent, such as $a^{-2}$ , you just take the reciprocal of it and then change the exponent sign, or in simple terms flip it. The reciprocal of a^{-2} and changing the exponent sign is is $\frac{1}{a^{2} }$ .

To demonstrate let’s solve the first problem:

$\frac{a^{-4}b^{-2} }{a^{2} b^{2} }$

Using what we just learned, we take the reciprocal and flip the sign of $a^{-4}$ and $b^{-2}$ , which are $\frac{1}{a^{4} }$ and $\frac{1}{b^{2} }$ respectively.
