9. You need an exact answer. So I will give you it but I'll also give you an approximation because it might help you understand it more.
Because we know the cosine fo theta, we can evaluate the inverse cosine of -2/3 first to find theta.
= 131.81° approx.
Because 131.81° is in the second quadrant its third quadrant partner is 228.19°. Which would make the sine 0.75 approximately.
But we need an exact answer I suppose so which is this disgusting mess.... I know it looks scary but it is basically all the steps we just did but without evaluating anything.
This can be simplified using: sin(x− y) = sinxcosy−cosxsiny
To...
answer:
10. Okay. So because we have a point we can say that...
θ =
sin(θ) = +sin()
11. arcsin(-0.37) = = -21.72°+2kπ or 201.72°+2kπ approx. where k has to be an integer
answer: idk if you want one or more solutions so I gave you them all.
12. arccos(-√3/2) =
Remember that "k" must be an integer.
answer: 5π/6
Answer:
(0, -2)
Step-by-step explanation:
You find an ordered pair by making x = 0, and solving for y, like so:
2x - y = 2
2(0) - y = 2
-y = 2 → Divide both sides by -1
y = -2
<u>Now your ordered pair for this would be (0, -2)</u>
Rate = 2 seats/11 minutes = 2/11 seats/min
Therefore the time required for s seats is
That is,
m = (11s)/2 min
When s = 16, obtain
When s = 19, obtain
Answers:
When s = 16, m = 88 min
When s = 19, m = 104.5 min
First divide them into regular shapes.
Then find the area of those regular shapes.
At the end add the areas of regular shapes in order to get the area of the regular shape.
Answer:
x=16
Step-by-step explanation:
6= x/4 + 2
Subtract 2 from both sides.
4= x/4
Multiply 4 to both sides.
x=16
Hope this helps!
