Mathematics

aksik [14]4 years ago

The order is 9^-2, 9^0, 9^3.

When an exponent is negative, the term can be moved from the numinator to the denominator (or vise versa) to change the negative exponent to a positive one. So 9^-2 becomes 1/9^2 = 1/81.

Anything to the 0th power becomes 1. So 9^0 is 1.

Finally, 9^3 is 729.

Alexandra [31]

Answer:

11

<em>or</em>

2(5)+2-3

Step-by-step explanation:

if a = 5 and b=2,

you add it into the expression.

2a + b -3 --> 2(5) + 2 - 3

all you have to do is replace the letters with the (given) numbers.

then, solve.

2(5) = 10

2-3= 1

10+1 =11

the answer is 11.

50 POINTS PLZ ANSWER CORRECTLY
belka [17]
Hey there! :D

So, we want to multiply that by 2. The table represents one year at Weatherford College. 

8,965*2= 17,930 

I heard the question mention 'reasonable'. It also said 'meet the cost'. So I would assume that 17,930 meets most of the cost. I think that's what it wanted to have. A couple thousand dollars may be reasonable, but will it meet the cost? Probably not. 

I would say "A" is the best answer.

I hope this helps!
