You haven't said what you need to "do" with it. I'm going to take a wild guess that you've been asked to 'factor' it. I don't have any step-by-step method for realizing that, and then doing it. But if you've done all the homework on multiplying twobinomials, and kind of almost understood it, then you might recognize this expression as the result AFTER two binomials got multiplied. Factoring it means to un-multiply it, and get the original two binomials. This is the product of (a-x) times (a+y).

What is <br><br><br> -9 x 1/2 <br><br><br> in fraction form

Angelina_Jolie [31]

Answer:

-9/2

Step-by-step explanation:

-9 is the same as -9/1

if we multiply -9/1 and 1/2 we multiply the numerators to get -9 and multiply denominators to get 2 or -9/2

Find sin θ and cos θ if tan θ= 1/4 and sin 0>0.

Serga [27]

Answer:

$\displaystyle \sin(\theta)= \frac{\sqrt{17}}{17}$

$\displaystyle \cos(\theta)= \frac{4 \sqrt {17} }{ 17 }$

Step-by-step explanation:

We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.

First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.

Recall that tangent is the ratio of the opposite side to the adjacent side.

Therefore, the hypotenuse is:

$h=\sqrt{4^2+1^2}=\sqrt{16+1}=\sqrt{17}$

So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.

Then it follows that:

$\displaystyle \sin(\theta)=\frac{1}{\sqrt{17}} = \frac{\sqrt{17}}{17}$

And that:

$\displaystyle \cos(\theta)= \frac{4}{\sqrt{17}} = \frac{4 \sqrt {17} }{ 17 }$

Find the product of<br><br>(1 + sinA) (1 + sinA) (1 + sinA)<br><br>helppp<br>

katovenus [111]

Answer:

1 + 3sinA + 3sin²A + sin³A

Step-by-step explanation:

Given

(1 + sinA)(1 + sinA)(1 + sinA) ← expand the last pair using FOIL

= (1 + sinA)(1 + 2sinA + sin²A) ← distribute

= 1 + 2sinA + sin²A + sinA + 2sin²A + sin³A ← collect like terms

= 1 + 3sinA + 3sin²A + sin³A
