Answer:
(8 (-1))
Step-by-step explanation:
Simplify the following:
8 (7 + 4×2 - 4 (11 - 7))
11 - 7 = 4:
8 (7 + 4×2 - 44)
4×2 = 8:
8 (7 + 8 - 4×4)
-4×4 = -16:
8 (7 + 8 + -16)
7 + 8 = 15:
8 (15 - 16)
15 - 16 = -(16 - 15):
8 (-(16 - 15))
| 1 | 6
- | 1 | 5
| 0 | 1:
8 (-1)
8 (-1) = (8 (-1)):
Answer: (8 (-1))
Factor:
2sin^2x-sinx = 0
sinx(2sinx - 1) = 0
Therefore the solutions are when:
sin x = 0
And
sinx = 1/2
So sinx = 0
is true when x = 0 and pi and all the angles coterminal with these points. Thus, the answer is x = pi*n, (where n is some integer)
sinx = 1/2
is true when x = pi/6 and 5pi/6 and the angles coterminal with these points.
Thus, the answer is x = pi/6 + 2pi*n (where n is some integer)
and x = 5pi/6 + 2pi*n (where n is some integer)
(x + 4) (x - 3)
a = 4
b = -3
a^2 + b^2 = ...
= 4^2 + (-3)^2
= 16 + 9
= 25
Answer:
1/5x+51=2x+42
Step-by-step explanation:
1/5 of x, the number, plus 51 is equal to 2 times the number plus 42.
