My first answer.  Lots of parts for five minutes. Took me that long to decode the question.  It looks like your multiplying where you're taking roots.


(\sqrt[4]{7})^5 = (7^{\frac 1 4})^5 = 7^{\frac 5 4}


<span>Choice A.  Next
</span>
(3^{2/3})^{1/6} = 3^{ \frac 2 3 \times \frac 1 6 } = 3^{\frac 1 9} = \sqrt[9]{ 3} &#10;&#10;&#10;

Choice B. 

\dfrac {2^{3/4} } {2 ^{1/2} }  = 2^{3/4 - 1/2} = 2^{1/4} = \sqrt[4] {2}&#10;


Choice C

Use trigonometric ratios to find the indicated side
iragen [17]

Answer:

a = 139.1

b = 56.2

Step-by-step explanation:

A. Reference angle = 68°

Opp = a

Hyp = 150

Therefore:

Sin 68 = opp/hyp

Sin 68 = a/150

150*sin 68 = a

a = 139.1 (nearest tenth)

B. Reference angle = 68°

Adj = b

Hyp = 150

Therefore:

Cos 68 = adj/hyp

Cos 68 = b/150

150*cos 68 = b

b = 56.2 (nearest tenth)

Write an equation in standard form of the line that passes through the given points:
Dafna1 [17]

Step-by-step explanation:

The standard form for a line is Ax+By=C

First, we need to find the slope, or change in y over change in x. For the first one, this is

\frac{6-(-2)}{2-2}, which is impossible to find as we cannot divide by 0, meaning that this is constant horizontally -- in this case, x=2. Thus, we have 1*x+0*y=2.

For the second one, we can find the slope by getting

\frac{0-4}{3-(-3)} =\frac{-4}{6 }  = \frac{-2}{3}. We can then take the point (3,0) (it can be any point on the line) and get our equation to be y-0 = (-2/3) (x-3). Converting this to standard form, we can expand this to get

y= (-2/3)*x +2

(-2/3)*x+1*y = 2

(a) Complete the table of values for y- 2x + 5<br> -<br> 0<br> 1<br> 2<br> 1<br> 5<br> Y
maxonik [38]

Answer:

Step-by-step explanation:

I think you meant y = -2x + 5.

x    y = -2x + 5

0                       5

1      -2(1) + 5 =   3

2     -2(2) + 5 =   1

Note that every time you increase x by 1, y decreases by 2.
