Evaluate 8-2. A. -16 B. -64 C. -1/64 D. 1/64

makvit [3.9K]

I'm assuming you meant to write 8^(-2) or $8^{-2}$ where the -2 is the exponent over the 8.

If my assumption is correct, then we use the rule $a^{-b} = \frac{1}{a^b}$

So,

$a^{-b} = \frac{1}{a^b}\\\\8^{-2} = \frac{1}{8^2}\\\\8^{-2} = \frac{1}{64}$

<h3>Answer: Choice D. 1/64</h3>

Given teo circles whose radii are 9" and 24", the ratio of thuer circumfrence is?

saul85 [17]

Answer:

The ratio is 3:8

Step-by-step explanation:

The circumference of a circle can be calculated using the formula;

C = 2 * pi * r

for 9 inches;

C = 2 * pi * 9 = 18 pi inches

For 24 inches;

C = 2 * pi * 24 = 24 pi inches

The ratio is thus;

18 pi : 48 pi

divide through by 6 pi

= 3: 8

Which term best describes a proof in which you assume the opposite of what u want to prove

ANTONII [103]

Answer:

The Latin phrase is "reduction ad absurd um", meaning reduction to absurdity. You assume the opposite and show that logically it leads to a contradiction and therefore cannot be true.

Hope this helps.

How many solutions does this system of Equations have x-2y=2 y=-2x+5

gayaneshka [121]

Answer:

One solution: x=2.4, y=0.2

Step-by-step explanation:

x-2y=2

y=-2x+5

x-2(-2x+5)=2

x+4x-10=2

5x=2+10=12

x=12:5=2.4

y=-2x+5=-2*2.4+5=-4.8+5=0.2
