Answer:
A.true
Step-by-step explanation:
The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.
Since beta is in the first quadrant, the final answer will be positive.
To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that
So, this means that
Answer:
See below.
Step-by-step explanation:
1) 7/4 + 5/8
= 14/8 + 5/8
= 19/8 or 2 3/8
2) 3/2 + 4/3
= 9/6 + 8/6
= 15/6
= 5/2 or 2 1/2
3) 2/3 + 10/7
= 14/21 + 30/21
= 44/21 or 2 2/21
4) 4 - 3/17
= 68/17 - 3/17
= 65/17 or 3 14/17
Answer -15 because it would be 15 but the negative would be turned into a negative again
