1/3n - 8 = -13 <== ur equation
1/3n = -13 + 8
1/3n = - 5
n = -5 * 3
n = -15
check..
1/3(-15) - 8 = -13
-5 - 8 = -13
-13 = -13 (correct)
so the number (n) = -15
Answer:
Step-by-step explanation:yes
Answer:
-0.41 radians
Step-by-step explanation
(Credit goes to calculista)
let
A---> the angle
if sin A=-0.4
then
A=sin-1(-0.4)
using a calculator
A=-23.578°----> the angle A belong to the IV quadrant
convert to radians
if pi radians--]----> 180°
x--------> -23.578°
x=-23.578*pi/180----> x=-0.41 radians

Answer:
Examples for the problem would be:
1) Robert started to run out of his house as fast as he can
2) But he slowed down when he met up with his friends
3) They then stopped at a park along the way
4) After stopping at the park, they ran the rest of the way to school hoping they wouldn't be late.
or
1) Robert met with his friends right outside his house and raced them to the next block
2) After Robert won, they all walked normally to the park
3) They then stopped at the park for a quick break
4) After realizing class was gonna start in a few minutes, they ran as fast as they could to school
Step-by-step explanation:
For the first part, you want Robert to be running at a normal running speed, such as him racing his friends or just running.
For the second part you want him to be walking at a slower pace.
For the third part you want them to not be moving
For the fourth part, you'll explain how/why they're moving so fast since the graph shows that he ran fastest at this time.
Hey there! I'm happy to help!
Let's think of this angle being put inside of a unit circle (a circle with a radius of one). This angle is going to stay inside the first quadrant, so all of its trigonometric ratios will be positive.
We are given that the sin of x is 1/5. To get the x by itself, we can just find the inverse sine of both sides to isolate the x.
x=sin
(1/5)
x≈ 11.536959
2x≈ 23.073918
Now, we just cosine this value.
cos2x≈ 0.92
I hope that this helps! Have a wonderful day!
