Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
56-16=40+23=63. ×=63
63-23=40+16=56
Reverse the problem it helps!
Firstly, you add 3 to both sides (as you've got to eliminate the -3), and this gives you;
7a=6+6a.
Then in order to get a alone, you need to subtract 6a from the right hand side (in order to counter balance) and this gives you;
1a=6
Therefore, a is equal to 6
Hope this helps :)
Answer:
It’s 40 I’m pretty sure because of the square. That’s how I was taught.
Hey there! I'm happy to help!
The domain is all of the x-values of a relation and the range is all of the y-values. When you write them out, you order the numbers from least to greatest and put it in brackets.
The domain of our relation is the x-values of these points, which are 11, 9, 7, and 5. The domain is {5,7,9,11}.
The range is the y-values, which are 1, 2, 3, and 4. So, the range is {1,2,3,4}.
Now you can find the domain and range given a few ordered pairs!
Have a wonderful day!
