Hello there! With the values of "x" and "y", they fill in the parenthesis. -3 + 5 is 2, because adding into a negative makes the number go up, or just simply subtracting 3 from 5 works as well. However, there is a 0 beside it, so we raise 2 to the 0 power. Anything that is raised to the 0 power is always equal to 1. And there is no other part of the question, so 1 is our answer. The answer is C: 1.
2 1/2 litres would be a reasonable amount of water assuming everyone drinks the same amount.
OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
Answer:
9x+4
Step-by-step explanation:
remove the parentheses
Step-by-step explanation:
tangent is the ratio of opposite (o) to adjacent (a). it means when an angle is getting bigger, it will impact to the ratio of o/a and reaching infinite value at the angle 90°.
