Answer:
7
Step-by-step explanation:
When the mean of two numbers is the same as one of the numbers, then the other number also has that same value. This is true for any kind of mean:
arithmetic, geometric, harmonic.
The other number would be 7.
__
The geometric mean (m) of a and b is ...
m = √(ab)
We have ...
7 = √(7b)
49 = 7b . . . . . square both sides
7 = b . . . . . . . .divide by 7
a = b = m = 7 in this case.
The area is what is given. Find the base and height and multiply that. Since, you done that, you simplify if any fraction is there. Then, you have an answer!
-2=-1/6(3)+b
-2=-0.5+b
-1.5+b
y=-1/6 -0.5

Answer:
Solving for we got and replacing this we got:
And then the best option for this case would be:
b.csc x
Step-by-step explanation:
For this case we have the following expression given:
We know from math properties that the definition for cot is
If we use this definition we got:
Now we can use the following identity:
Solving for we got and replacing this we got:
And then the best option for this case would be:
b.csc x
