The answer would be (8/11,0) as the x-intercept
Answer:
D
Step-by-step explanation:
Well it is Friday so its 8.5 each ride.
8.5r which is basically how many rides she can go on after spending 125 on the admission
N would equal 45° since the tiny square means its 90°. 90-45=45.
Answer:
13 +13 +14 ensures he is getting the smallest amount so its 14
Step-by-step explanation:
We have that
2sin²<span>x - sinx - 3 = 0
</span>
Let
A------> sin x
so
2A²-A-3=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solutions are
A=-1
A=1.5------> is not solution because sin x <span>can not be 1.5
the solution is
A=-1
therefore
sin x=-1
x=arc sin(-1)=-90</span>°
the answer is
sin x=-1x=-90° or 270°
