The distance formula is based on the Pythagorean Theorem:

Distance = Square Root [(X2 - X1)^2<span> + (Y2 - Y1)^</span>2<span>]
</span>Distance = Square Root [(7 -1)^2 + (-7 -1)^2]
Distance = Square Root [ 6^2 + -8^2]Distance = Square Root [ 36 + 64 ]Distance = Square Root [100 ]Distance = 10

Someone please HELP!?

 A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side.

For example

x^{-2}=\frac{1}{x^2}

or

( \frac{2}{5} )^{-4}=( \frac{5}{2} )^4

***************************************
(8r^{-5})^{-3}

(8* \frac{1}{r^5} )^{-3} \\\\( \frac{8}{r^5} )^{-3}&#10; \\  \\ ( \frac{r^5}{8} )^3&#10;\\\\ \mathrm{Apply\:exponent\:rule}:\quad *\left(\frac{a}{b}\right)^c=\frac{a^c}{b^c} \ \ \ \ \ \ \ \ \ \ \ \   *(a^b)^c=a^{bc}&#10; \\\\( \frac{r^{15}}{8^3} )&#10;\\\\( \frac{r^{15}}{512} )

The answer is "D"

Solving for an Unknown Using the Distributive Property
ArbitrLikvidat [17]

<em><u>Complete Question:</u></em>

The equation a= 180(n-2)/n represents the angle measures, a, in a regular n-sided polygon. When the equation is solved for n, n is equal to a fraction with a denominator of a – 180. What is the numerator of the fraction?

<em><u>Answer:</u></em>

The numerator of fraction is -360

<em><u>Solution:</u></em>

Given that,

<em><u>The equation represents the angle measures, a, in a regular n-sided polygon is:</u></em>

a = \frac{180(n - 2)}{n}

We have to solve the equation for "n"

Rearrange the equation

a \times n = 180(n - 2)\\\\a \times n = 180n - 360\\\\an - 180 n = -360\\\\Take\ n\ as\ common\ factor\\\\n(a-180) = -360\\\\n = \frac{-360}{a - 180}

Thus the numerator of the fraction is -360

Which set of numbers CANNOT represent the lengths of the sides of a triangle?
posledela

Answer:

C

Step-by-step explanation:

The general rule is that any 2 must exceed the third in order for a triangle to form. If any one is an exception, it won't work.

A will form a triangle. Any 2 exceeds the third.

B also forms a triangle. Same rule.

C  does not work. 7 + 11 = 18 which is the value of the third leg.

D words Any two exceeds the 3rd.
