Answer:
our answer will be in quadrant 1 only.
Step-by-step explanation:
From the
cos−1(1) we have the side adjacent to ∠θ=1 and the side hypotenuse=2 . So this is a 30∘−60∘−90∘ triangle and θ=60∘therefore the opposite to ∠θ=√3.
Note that from the restrictions for the range of inverse circular functions cos−1x is restricted to quadrants 1 and 2 and since the argument is positive 12 our answer will be in quadrant 1 only.
Answer:
10 + 2^3 * 4-1 = 41
Step-by-step explanation:
You just have to use PEMDAS.
First you see there are no parenthesis.
So you start with exponents, 2^3 = 8.
Then you do multiplication, 8 * 4 = 32.
Then you see there is no division.
So you move to addition, 10 + 32 = 42.
Then you go to subtraction, 42 - 1 = 41.
Hope this helps.
Hey!
You can make a proportion:
![\frac{2}{\$ 4.20} = \frac{5}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B%5C%24%204.20%7D%20%3D%20%5Cfrac%7B5%7D%7Bx%7D%20%20)
Cross multiply
![\$ 4.20 \times 5 = \$ 21](https://tex.z-dn.net/?f=%20%5C%24%204.20%20%5Ctimes%205%20%3D%20%5C%24%2021%20)
Divide by 2
![\$ 21 \div 2 = \$ 10.5](https://tex.z-dn.net/?f=%20%5C%24%2021%20%5Cdiv%202%20%3D%20%5C%24%2010.5%20)

Good luck and hope this helps! :)
