If n-2 = 1/16, then n could be which of the following?

arlik [135]

The answer is E.4

The equation is: $n ^{-2}= \frac{1}{16}$

Since $x^{-a}= \frac{1}{ x^{a} }$ , then $n^{-2} = \frac{1}{n^{2} }$

Therefore, the equation is:
$\frac{1}{ n^{2} } = \frac{1}{16}$
⇒ $n^{2} = 16$
$n= \sqrt{16}=4$

Given the formula 1/2(base)(height), what area can you find? a. area of a parallelogram c. area of a trapezoid b. area of a tria

CaHeK987 [17]

Answer: b. Area of a triangle.

Step-by-step explanation:

a. The formula for calculate the area of a parallelogram is:

$A_{p}=b*h$

Where "b" is the base and "h" is the height.

Then, with the given formula you can't find the area of a parallelogram.

b. The formula for calculate the area of a triangle is:

$A_{tr}=\frac{1}{2}(b*h)$

Where "b" is base and "h" is the height.

Then, with the given formula you can find the area of a triangle.

c. The formula for calculate the area of a trapezoid is:

$A_{tp}=\frac{h}{2}(B+b)$

Where "B" is the larger base ,"b" is the smaller base and "h" is the height.

Then, with the given formula you can't find the area of a trapezoid.

d. The formula for calculate the area of a rectangle is:

$A_{r}=l*w$

Where "l" is the lenght and "w" is the width.

Then, with the given formula you can't find the area of a rectangle.
