Option 1.
sin(2x) = 2sin(x)cos(x)
cos(2x) = 1 - 2sin(x)^2
Answer: D) (x+1)(x + 2)(x-3)
This is because the roots are x = -1, x = -2 and x = 3
Simply get all the numbers to each side to have 0 on the right side
x = -1 turns into x+1 = 0
x = -2 turns into x+2 = 0
x = 3 turns into x-3 = 0
The three factors are (x+1), (x+2) and (x-3)
Which leads to (x+1)(x+2)(x-3)
Here is the answer for your question f2= 7x+7
Answer:
Step-by-step explanation:
Using that triangle in the corner the opposite side and adjacent side is 2 and 5 respectively
square of c = square of b plus square of a
in this case a is our hypotenuse
c square = 2 square plus 5 square
c square = 4 plus 25
c square = 29
c is the root of 29
Answer:
part 1 its telling you to measure people
part two is telling you to put it into a graph and find the rate of change. more than likely there won't be a rate of change for you
part three:
y = 0.860x + 3.302
y = 0.860(17) + 3.302
0.860(17) = 14.62
14.62 + 3.302 = 17.922
y = 17.922
sorry this is as far as i had gotten
