Assuming that the x is not part of the ^-1 the range would be
[0,π/2) U (π/2,<span>π]</span>
Answer:
380
Step-by-step explanation:
640/2=320
320-60=260
640-260=380
Answer:
D. $70
Step-by-step explanation:
you can first think that the first tree is $25 plus the nine trees for 5 dollars so
5x9=45
45+25=70
Hope this helps :D
Answer:
x = 10 , 45 degrees.
Step-by-step explanation:
This seems a tricky one .
I guess we can use sin A + sin B = 2 sin (A+B)/2 cos (A - B) / 2
so sin 5x + sin x = 2 sin 3x cos 2x so our equation becomes
2 sin 3x cos 2x - cos 2x = 0
cos 2x ( 2 sin 3x - 1) = 0
so 2 sin 3x = 1
sin 3x = 1/2
giving 3x = 30 degrees and x = 10 degrees
or cos 2x = 0
so 2x = 90
giving x = 45 degrees.
Answer:
56m²
Step-by-step explanation:
First, find the area of the entire rectangle:
10 × 8 = 80
Then, find the area of the triangle:
1/2(6)(8) = 24
Finally, subtract the two areas to find the shaded area:
80 - 24 = 56
