After using the property of power, the expressions as a power of the number a is (a^3)^{-2} = a^{-6} , (a^{-1}\cdot a^{-2})^{-3} = a^{9} and ((a^2)^{-2})^2=a^{-8} .

In the given question we have to solve the given expressions as a power of the number a where a≠0.

The first given expression is (a^3)^{-2}.

Using the property of multiplication of power; (a^m)^n=a^{mn}.

Simplifying the expression.

(a^3)^{-2} = a^{3*(-2)}

(a^3)^{-2} = a^{-6}

The second expression is (a^{-1}\cdot a^{-2})^{-3}

Using the property of multiplication of power; (a^m)^n=a^{mn}.

(a^{-1}\cdot a^{-2})^{-3} = a^{(-1)\times(-3)}\cdot a^{(-2)\times(-3)}

(a^{-1}\cdot a^{-2})^{-3} = a^{3}\cdot a^{6}

Using the property of sum of power a^m\cdot a^n=a^{m+n}

(a^{-1}\cdot a^{-2})^{-3} = a^{(3+6)}

(a^{-1}\cdot a^{-2})^{-3} = a^{9}

The third expression is ((a^2)^{-2})^2.

Using the property of multiplication of power; (a^m)^n=a^{mn}.

((a^2)^{-2})^2=((a^2)^{(-2)\times2})

((a^2)^{-2})^2=(a^2)^{-4}

Again using the property of multiplication of power; (a^m)^n=a^{mn}.

((a^2)^{-2})^2=a^{2\times(-4)}

((a^2)^{-2})^2=a^{-8}

Which line is a graph of the equation: 2x + 5y = -10?
Anit [1.1K]

Answer: D. line d

Step-by-step explanation:

Answer: D. line d

A function is general describe as y = mx + b, so we need to set this function in y form.

2x + 5y = -10

       5y = - 2x - 10             (Subtract 2x from both side, to make sure there are only y value in the left side)

         y = - 2/5x -10/5       (Divide by 5 from both side)

         y =  -2/5x - 2           (Simplified)

-2/5x was the <em>m</em> or the slope, it shows how the line was change. -2/5x is negegative, which means is decreasing, and going downward, only line b and d fits.

-2 is the y-intercept, where y is equal to 0, (-2,0)

The y-intercept for line b is (2,0), so it can't be. Thus, the y-intercept for line d is (-2,0), so it fit.

The width and the length of a rectangle are consecutive even integers. if the width is decreased by 3 inches, then the area of t
solong [7]
Consecutive even integers =   x,  x + 2

(x - 3)(x + 2) = 24               Since width x, was decreased by 3.

If we test x = 6,    (6 - 3)(6 + 2) =   3*(8) = 24

So to    <span>(x - 3)(x + 2) = 24,   x = 6 satisfies it.

The original rectangle = </span><span>x,  x + 2 =   6,  6 + 2 =    6,   8
</span><span>
Original area = 6*8 = <span>48 square inches</span></span>

A pattern follows the rule "Starting with three, every consecutive line has 2 less than twice the previous line."
SVEN [57.7K]
"Starting with three, every consecutive line has 2 less than twice the previous line."

this statement means that
your staring line has 3 marbles. You multiply the 3 marblesby 2 so
3x2=6
And then you minus it by 2
6-2=4

which means that you'll get 4 marbles for the next line.

So to get your 6th line, you count how many marbles is on the 5th line but since your diagram doesn't have the 5th line you have to figure out the 5th line by counting how.many marbles is on the 4th line.

4th line = 10 marbles

10×2=20
20-2=18

5th line = 18

18×2=36
36-2=34

So the 6th line has 34 marbles.

Margin of error: 0.04; confidence level: 95%; from a prior study, bold p with bold overparenthesis on top is estimated by the de
GrogVix [38]

Answer: 235

Step-by-step explanation:

The formula to calculate the sample size  :-

n=(\hat{p}(1-\hat{p}))(\dfrac{z_{\alpha/2}}{E})^2

Given :  Estimated proportion \hat{p}=0.89

Margin of error : E=0.04

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2} =1.96

Now, the required sample size will be :-

n=(0.89(0.11))(\dfrac{(1.96)}{0.04})^2

\Rightarrow\ n= 235.057\approx235

Hence, the required minimum sample size = 235
