Assuming you meant
![y = \frac{7}{ \sqrt{8x+10} }](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B7%7D%7B%20%5Csqrt%7B8x%2B10%7D%20%7D%20)
Then you can compose the function g(x)
![g(x)= \sqrt{8x+10}](https://tex.z-dn.net/?f=g%28x%29%3D%20%5Csqrt%7B8x%2B10%7D%20)
With the function
![f(x)= \frac{7}{x}](https://tex.z-dn.net/?f=f%28x%29%3D%20%5Cfrac%7B7%7D%7Bx%7D%20)
Because f (g(x) ) means that you first find (calculte)
![\sqrt{8x+10}](https://tex.z-dn.net/?f=%20%5Csqrt%7B8x%2B10%7D%20)
and second you divide 7 by g(x) to obtain 7 / [√(8x+10) ].
Answer:
Step-by-step explanation:
No, there are 4 quarts in 1 gallon, so there are
5(4) = 20 quarts in 5 gallons
From the given figure, it can be seen that 13x = 15x - 8 because they are vertical angles and thus are equal.
13x = 15x - 8
15x - 13x = 8
2x = 8
x = 8/2 = 4
Thus, 15x - 8 = 15(4) - 8 = 60 - 8 = 52.
RT is a diameter, which means that mRT = 180
mRV + mVU + 52 = 180
mRV + mVU = 180 - 52 = 128
Now, given that mRV = mVU,
Thus, 2mVU = 128
Therefore, mVU = 128 / 2 = 64°
