Answer:

$9^{-7}$ and $9^{-2}$

Step-by-step explanation:

using the rules of exponents

• $(a^m)^{n}$ = $a^{mn}$

• $a^{m}$ × $a^{n}$ = $a^{(m+n)}$

• $\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$

given ( $9^{5}$ × $9^{-9}$ ) / $9^{3}$

= $\frac{9^{5+(-9)} }{9^{3} }$ = $\frac{9^{-4} }{9^{3} }$ = $9^{-4-3}$ = $9^{-7}$

given $(9^4)^{3}$ × $9^{-14}$

= $9^{12}$ × $9^{-14}$

= $9^{12+(-14)}$ = $9^{-2}$

Ellen has a bag with 3 red marbles and 2 blue marbles in it. She is going to randomly draw a marble from the bag 300 times, putt

Contact [7]

Answer:

120

Step-by-step explanation:

Blue marbles = 2

Red marbles = 3

Total marbles = 2 + 3 = 5

If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :

P(drawing a blue marble) = number of blue marbles / total number of marbles

= 2 /5 = 0.4

Predicted number of times blue is drawn in 300 selections :

300 * 0.4 = 120

Approximately 120 times

Find an expression for a rational function f(x) that satisfies the conditions: a slant asymptote of y = 2x, vertical asymptote a

lesantik [10]

Complete Question

The complete Question is attached below

Answer:

Option D

Step-by-step explanation:

From the question we are told that:

Slant asymptote of $y = 2x$

Vertical asymptote at $x = 1,$

Points (0,6)

Generally the Denominator is give as

With

Vertical Asymptote at

$x -1=0$

Therefore

Denominator = (x-1)

Generally Slant asympote 2x Gives the Coefficient of the numerator

Therefore

The expression for a rational function f(x) that satisfies the conditions

$F(x)=\frac{2x^2-2x-6}{x-1}$

Option D
