1/2+2/5
First we need to find a common denominator in this case it's 10. In order to change the denominators we need to multiply. 1/2*5/5=5/10
2/5*2/2=4/10
Now we can add our new fractions
5/10+4/10=9/10
Your answer is 9/10 it can not be simplified.

Find the exact value of each expression . Do not use a calculator .

The attached table is one that it is convenient for you to memorize as long as you're taking courses involving angles. For the inverse functions, find the column corresponding to the function, then look for the value in that column. The angle at the beginning of that row is the answer to your question.

8. \cos^{-1}(0)= 90^{\circ}=\dfrac{\pi}{2}

9. \sin^{-1}(1)= 90^{\circ}=\dfrac{\pi}{2}

10. \tan^{-1}\left( \dfrac{\sqrt{3}}{3} \right)=30^{\circ}=\dfrac{\pi}{6}

How to find the answer
KATRIN_1 [288]
Use this equation:
A = P(1+r)^t

Where A is the final amount
P is the initial amount
r is the annual rate
t is the time in years

P = 1500
r = 0.07
t = 3

A = 1500 (1.07^3)
≈ $1837.56

Have an awesome day! :)

The inequality is false.

If X = 11,

11 - 5 > 9 = false.

11 - 5 = 6

6 > 9 is a false inequality as 6 is not greater than 9.

Therefore, the inequality is false.
