Answer:

C

Step-by-step explanation:

First things first, we need to simplify (8^2)^-4. When a number is raised to a power, and the result of that is raised to another power, the two powers can be multiplied together to simplify. In this case, 2 * -4 = -8, so the question is asking how 8^-8 can be written.

8^-8 is the same as multiplying 8 8s together, and then finding the reciprocal (put it into a fraction where the original number is the denominator and 1 is the numerator).

Therefore, the 1 over the 8 8s multiplied together is the correct answer.

Given the equation 2X +4/3 Y equals one and Y -9/13 x=9 by what Vector would you multiply the first equation so that combining t
Mila [183]

Answer: Option B

B. \frac{9}{26}

Step-by-step explanation:

We have the following equations:

2x + \frac{4}{3}y = 1       (1)

y -\frac{9}{13}x=9          (2)

Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.

Then we must multiply the number "a" by a value z such that when adding az + b the result is zero.a = 2

b = -\frac{9}{13}

So

2z-\frac{9}{13} = 0

We solve the equation for z

2z=\frac{9}{13}

z=\frac{9}{26}

The first equation must be multiplied by a value of \frac{9}{26}

Calculate the area of a circle with a radius of 8 feet
Ulleksa [173]

Answer:

201.06 square feet

Step-by-step explanation:

area of a circle is given by πr², where π = 3.1416

A = 3.1416 * 8²

A = 3.1416 * 64 = 201.0624 square feet

A = 201.06 square feet

Simplify. Rewrite the expression in the form k⋅y^n. (2y^4)^3
N76 [4]

Answer:

The answer is

<h2>{8.y}^{12}</h2>

Step-by-step explanation:

(2y⁴)³

Using the rules of indices

That's

<h3>( {ax})^{b}  =  {a}^{b} . {x}^{b}</h3>

So for the above expression we have

<h3>( {2y^{4} })^{3}  =  {2}^{3} . {y}^{4 \times 3}</h3>

Simplify

We have the final answer as

<h2>8.y¹²</h2>

Hope this helps you

Help w this plsss,!,!,, 20pointsss
Kay [80]

Answer:

Area = Length × width

16 = (3x +2 ) × ( x)

16 = 3x² +2x

3x² +2x -16=0

( 3x+8 ) ( x -2 ) =0

3x +8=0 —> 3x = – 8 —> x = – 8/3 —> x = – 2.6

x-2=0 —> x = 2

I hope I helped you^_^
