In an inverse function, the x-values and y-values switch. So if (a,b) is a point in the f(x) function, then (b,a) is a point in the f^(-1)(x) function.
Switch all x and y-values in the function.
Answer:
Step-by-step explanation:
Prove this:
volume of cylinder = volume of cone + volume of sphere
πr²h = (1/3)πr²h + (4/3)πr³
Note that the factor πr² is common to all three of these formulas. Factoring out this πr², we get:
h = h/3 + (4/3)r
or: 3h/3 = h/3 + 4r/3
or: 3h = h + 4r
or: 2h = 4r
or: h = 2r
Note that 2r is the diameter of the sphere, and that this diameter is twice the radius. Thus, in view of the givens. this equation h = 2r is correct.
Thus, the volume of the cylinder is equal to the volume of the cone PLUS the volume of the sphere.
Clearly, we can see that x+2 is a factor of the given polynomial.
Answer:
2.24
Step-by-step explanation:
You can just plug this into a calculator, then round up if needed. The exact square root is 2.2360679775 rounded to 2.24.
2.7 is already rounded to the nearest tenth.
