(f/g)(x)and (f/g)(7)
Phoenix [80]

Answer:

(\frac{f}{g})(x)=\frac{f(x)}{g(x)}\\\\(\frac{f}{g})(7)=\frac{f(7)}{g(7)}

Step-by-step explanation:

Division operation of function:If\ f(x)\ and\ g(x)\ are\ two\ functions\ then\ (\frac{f}{g})(x)=\frac{f(x)}{g(x)}

Here\ we\ have\ to\ find\ (\frac{f}{g})(7)\\\\(\frac{f}{g})(7)=\frac{f(7)}{g(7)}

Example:

Take\ f(x)=3x^2+1,\ g(x)=x+1\\\\(\frac{f}{g})(x)=\frac{f(x)}{g(x)}\\\\(\frac{f}{g})(x)=\frac{3x^2+1}{x+1}\\\\f(7)=3\times 7^2+1\\\\f(7)=3\times 49+1\\\\f(7)=148\\\\g(7)=7+1\\\\g(7)=8\\\\(\frac{f}{g})(7)=\frac{f(7)}{g(7)}\\\\(\frac{f}{g})(x)=\frac{148}{8}

Walter is mixing cement for his new patio . He knows he need to use a water-to-cement ratio of 20 to 30 . What percent of his to
kherson [118]
If his water to cement ratio is 20 to 30, this means that if he uses 20 liters of water, he'd use 30 liters of cement.

The total mixture would then be 20+30=50 liters.

and the water would be 20/50=0.4 or 40% of the total mixture.

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations)
klemol [59]

Answer:

52\pi

Step-by-step explanation:

The total shaded are will be the area of big circle - not shaded circle + little shaded circle.

The are of big shaded circle: \pir^{2} So, A=\pi(8^2)= 64\pi

The are of not shaded circle: \pi r^{2} So, A= \pi(4^2)= 16\pi

The are of little shaded cirlce: \pi r^{2} So, A=\pi(2^2)= 4\pi

64\pi - 16\pi + 4\pi= 52\pi
