Hope this helps!
T = 3π/2
Let's transform 3π/2 on degree
We know, π = 180° on trigonometric
Then,
3π / 2 = 3.(180°)/2
3π / 2 = 270°
Now let's evaluate.
Sin(270°) = Sin(-90°)
As Sin(-x) = - Sin(x)
Then,
= - Sin(90°)
= - 1
It is possible
_______________
2 example:
Csc(270°) = ?
As Csc(x) = 1 / Sin(x)
Then,
Csc(270°) = 1 / Sin(270°)
= 1 / - 1
= -1
It is possible
_____________
3 example:
Cos(270°) = Cos(-90°)
As Cos( -x) = Cos(x)
Then,
= Cos(90°)
= 0
_______________
4 example:
Sec(270°) = ?
As Sec(x) = 1 / Cos(x)
Then,
Sec(270°) = 1 / Cos(270°)
= 1 / 0
It isn't possible division by zero
______________
5 example
Tg(270°) = ?
As Tg(x) = Sin(x) / Cos(x)
Then,
Tg(270°) = Sin(270°) / Cos(270°)
= - 1 / 0
It isn't possible too.
______________
Now the six and last example
Cot (270°) = ?
As Cot(x) = 1 / tg(x)
Cotg (x) = Cos(x) / Sin(x)
Then,
Cot(270°) = Cos(270°) / Sin(270°)
= 0 / -1
= 0
It is possible
Answer:
0.722
Step-by-step explanation:
First of all add up the sections 1 to 8 to make sure they add to 360
They do actually.
- 1 10
- 2 20
- 3 30
- 4 40
- 5 50
- 6 60
- 7 70
- <u>8 80</u>
Total 360
This is an area question. Every time you spin the spinner, it must come to an area labeled 1 to 8.
You could do this by setting up a ratio of each section and subtract the section for 3 and 7. That's the long way.
The shorter way is to add up the degrees for 3 and 7 and subtract them from the total (360)
Area 3 + area 7 = 30o + 70o = 100 degrees.
So the probability of landing in 3 or 7 is 100 / 360 = 0.278 (rounded)
The probability of Not landing on 3 or 7 is 1 - 0.278 = 0.722
Answer:
18
Step-by-step explanation:
1) 90 --- 100%
x --- 20%
x = 90*20/100 = 18
2)
20 % = 20/100 = 0.2
20 percent (0.2) of (*) 90 = 0.2*90 = 18
