Sin(13pi/2) in periodic function

Mathematics
1 answer:
Nataliya [291]3 years ago
5 0
Answer: 1
13pi/2 can be simplified onto 6 pi/2, so it goes around the unit circle 6 times and left with pi/2. the coordinates of pi/2 is (0,1). the trigonometric function sin is y/r. since r is always 1 on the unit circle, the answer is the y value, in this case it is 1.

PLZ HELP AND SHOW YOUR WORK &lt;3333<br><br><br> Substitution.<br><br> 3x+2y=11<br><br> y=5x-1
liraira [26]
Hey there! :D

Substitute y for 5x-1. 

3x+2y=11

y=5x-1

3x+2(5x-1)=11

3x+10x-2=11

13x-2=11

13x=13

x=1

Now, plug that in to find y.

y=5x-1

y=5(1)-1

y=5-1

y=4

(1,4) <== the solution

I hope this helps!

To check if distances can be a triangle add the smaller two distances together. If the sum is larger (not equal to) than the longest distance then it is a possible side. For example, 2,2,4 or 1,2,5cannot be a triangle, 2,3, 4 can be a triangle because 2+3 is greater than 4.

Sec is the length of the hypotenuse divided by the length of the adjacent side.

Ivan and Tanya share £150 in the ration of 4:1
Zarrin [17]

Answer:

Money Ivan gets   extra = 120 - 30 (or 3x) = 90

Step-by-step explanation:

Ivan = 4x

Tanya = 1x

Total = 150

4x + x = 150

5x = 150 ;  x = 150 / 5 = 30

Ivan = 4x = 120

Tanya = 1x = 30

Money Ivan gets   extra = 120 - 30 (or 3x) = 90
