Answer:

1) [tex]9^{2}=81[/tex]

2) [tex]7=log_{2}(128)[/tex]

Step-by-step explanation:

1)

We need to use the property of power and logarithms, particularly this:

[tex]a=x^{log_{x}(a)}[/tex] (1)

So, let's take take the exponent:

[tex]9^{log_{9}}(\frac{1}{81})=9^{-2}[/tex]

[tex]\frac{1}{81}=9^{-2}[/tex]

now, we can write the negavitve power as:

[tex]\frac{1}{81}=\frac{1}{9^{2}}[/tex]

So, the aswer will be:

[tex]9^{2}=81[/tex]

2)

Applying equation 1, let's take log in base 2 on each side of the equation

[tex]log_{2}(2^{7})=log_{2}(128)[/tex]

using the power definition in log, we have:

[tex]7log_{2}(2)=log_{2}(128)[/tex]

Therefore, the answer is:

[tex]7=log_{2}(128)[/tex]

I hope it helps you!

Answer:

The interior angles of a triangle add to 180°:a + b + c = 180°

Angles c and d make a straight angle, which is 180°:d + c = 180°

So d + c equals a + b + c:d + c = a + b + c.

Subtract c from both sides:d = a + b.

Step-by-step explanation:

Notice that v points into the third quadrant since both of its components are negative. If you want a vector to point in the same direction, it would need to have the same sign on its components. So C is the correct choice.

The factor of 1/√80 comes from normalizing the vector v. Its norm/magnitude is

|v| = √((-4)² + (-8)²) = √(16 + 64) = √80

so the unit vector that points in the same direction as v is simply v / |v|.

Answer:

Angle 1: 130

Angle 3: 130

Angle 5: 50

Angle 6:  130

Step-by-step explanation:

If angle 2 is 50, that means 4,5, and 7 are 50 as well

Also, if we know angle 2 is 50, we know 1,3,8, and 6 are 130 since a line is always 180 (so subtract 50)

Step-by-step explanation:

V = Bh        B = area of the base           h = height

The base is a circle, so [tex]B = \pi r^{2}[/tex]

320π = [tex]\pi r^{2} (20) = 20\pi r^{2}[/tex]

[tex]r^{2} = \frac{320\pi }{20\pi } = 16[/tex]

Answer:

$5

Step-by-step explanation:

Set up a system of equations

let b be the cost of a bow

let w be the cost of a roll of wrapping paper

This means that

[tex]5b + w = 10\\b + w = 6[/tex]

Subtract the two equations

[tex]5b + w = 10\\- (b + w = 6)\\4b = 4\\b = 1[/tex]

Plug this into the equation b + w = 6

1 + w = 6

w = 5.

This means the cost of a bow is $1 and the cost of a roll of wrapping paper is $5.
