Answer:
If f(1)=0 then 1 is a root and (x-1) is a factor of f(x). divide f(x) by (x-1). you now have a quadratic. Find its roots by methods you know.
actually this factors by grouping:
f(x)=x³+3x²-x-3
= x²(x+3)-1(x+3)
=(x+3)(x²-1)
=(x+3)(x-1)(x+1) // difference of squares
By zero product property roots are
-3, -1, 1

Suppose sin(x) = -3/5 and cos(x) < 0. What the value of cos(2x)?
A) -16/25
B) -7/25
C) 7/25
D) 16/25
Answers
Answer:
The value of cos(2x) = 7/25
Hence, option C is true.
Step-by-step explanation:
Using the trigonometric identity
cos 2x = 1 - 2sin²x
Given
sin(x) = -3/5cos(x) < 0so substituting the values
cos 2x = 1 - 2sin²x
= 1 - 2 (-3/5)²
= 1 - 2 (9/25)
= 1 - 18/25
= 7/25
Therefore,
The value of cos(2x) = 7/25
Hence, option C is true.

35% means 35 per hundred. 35/100. simplify and write as 7/20.
0.64 means its 2 zeros left of regular number. 64/100.
82% means 82 per hundred. 82/100. move decimal 2 spaces to left (division is left, multiplication is right). 0.82.
4/5. try to make denominator 100. multiply both numerator and denominator by 20. 80/100. move decimal 2 spaces to the left. 0.8.
14/50. try to make denominator 100. multiply both numerator and denominator by 2. 28/100. 28%

Answers
Answer:
it is AD l l DC so ots B
Step-by-step explanation:
Answer
If the line segment AB is parallel to the line segment DC then, m∠1=m∠D by corresponding angles.
What is corresponding angle?Congruence and similarity tests in geometry involve comparing corresponding sides and angles of polygons.
Each side and angle in one polygon is paired with a side or angle in the second polygon, with the order of adjacency preserved.
One is an exterior angle (beyond the parallel lines), while the other is an interior angle (inside the parallel lines).
Corresponding angles and transversal lines are defined. Corresponding angles are a subset of angle pairs. Angles on the opposite side of the transversal are referred to as alternate angles.
If line segment AB is parallel to line segment DC,
m∠1=m∠D, by corresponding angles
If line segment AD is parallel to line segment BC,
m∠3=m∠B, by corresponding angles
Thus, this can be concluded regarding the given scenario.

(0, 3) (2, 7) (-1, 1) (5, 13)
Answers
Answer:
y = 2x + 3
Step-by-step explanation:
First things first we have to find the slope. To do so you simply choose two of the ordered pairs and use the formula:
y2 - y1 / x2 - x1
I will use (0, 3) and (2, 7).
7 - 3 / 2 - 0
4 / 2
2
let’s double check by using the other set of ordered pairs.
(-1, 1) and (5,13)
13-1 / 5 + 1
12 / 6
2
Our slope is 2!
Next we will use the point-slope formula:
y - y1 = m (x - x1)
we will do this with one of the ordered pairs, since they all lie on the same line the answer will be the same each time.
I will use (2, 7).
y - 7 = 2(x - 2)
distribute:
y - 7 = 2x - 4
add 7 to both sides:
y = 2x + 3
Just to be sure that i didn’t make any mistakes i will double check by using another ordered pair.
I will use (-1, 1)
y - 1 = 2 (x + 1)
distribute:
y - 1 = 2x + 2
add 1 to both sides
y =2x + 3
There we have it! The answer is:
y = 2x+ 3

A website sells sweaters. The amount of sales p(c) varies directly with the number of customers c. Eight customers bought a total of $335 worth of sweaters. Which equation can be used to find the sales for c customers? p(c) = 41.88c p(c) = 4188c p(c) = 41.88c p(c) = 4188c
Answers
Answer: p(c) = 41.88c
Step-by-step explanation:
From the question, we are informed that a website sells sweaters and that the amount of sales p(c) varies directly with the number of customers c.
We are further told that eight customers bought a total of $335 worth of sweaters.
The equation that can be used to find the sales for c customers will be:
= 335/8
Therefore, the answer is p(c) = 41.88c
= 41.88
