To solve for the last side of the triangle, use the Pythagorean Theorem:
(8)^2 + x^2 = (9)^2
x = sqrt of 17
However, this is a NEGATIVE sqrt 17 because the terminal side is in quadrant 4, meaning that this side is under the X-axis and therefore negative.
Now that you know the side opposite of u in the triangle, do opposite/hypotenuse.
sin u = -(sqrt 17)/9
Answer:
10x^2-25x-35
Step-by-step explanation:
FOIL means first, outer, inner, and last.
The first term of each pair is 2x and 5x.
The outer term of each pair is 2x and 5.
The inner term of each pairs are -7 and 5x.
The last term of each is -7 and 5.
Now we just have to multiply the terms I pairs above:
First: (2x)(5x)=10x^2
Outer: (2x)(5)=10x
Inner: (-7)(5x)=-35x
Last: (-7)(5)=-35
------------------------------Add the terms:
10x^2-25x-35
In the expression given, the "n" is referring to a certain term, in this case, it would be the 16th term. So in order to find the 16th term, all you have to do is substitute n as 16 in the expression, so the answer is
. So the 16th term of the sequence is -29.
To simplify the equation, we have y = 
<h3>How to simply the expression</h3>
Given the expression
y-8 = 3/4x [x-(-6)]
First, expand the bracket
= 
Make 'y' the subject of formula
y =
Thus, to simplify the equation, we have y =
