Answer:

x⁴ - x³ + 2x - 6

Step-by-step explanation:

Apparently i cannot write the equation needed so we will call it r(x) and the 2 given equations, a(x) and b(x) respectively

r(x) is the same as a(x) - b(x)

a(x) - b(x)

= x⁴ - 3x² + 5x - 7 -(x³ - 3x² + 3x -1)

= x⁴- x³ + (- 3x² + 3x²) + (5x - 3x) + (- 7 + 1)

= x⁴ - x³ + 2x - 6

A cylinder has a volume of 105 cubic centimeter what is the volume of a cone with the same base and height?

pychu [463]

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

$V_1=\pi r^2H$

r - radius

H - height

The formula of a volume of a cone:

$V_2=\dfrac{1}{3}\pi r^2H$

If the cylinder and the cone have the same base (radius) and the same height, then the volume of the cone is three times smaller than the volume of the cylinder.

$V_2=\dfrac{1}{3}\underbrace{\pi r^2H}_{V_1}$

Therefore:

$V_2=\dfrac{1}{3}V_1\toV_2=\dfrac{1}{3}\cdot105\ cm^3=35\ cm^3$

And simplifying that we get

307.35

And since there can't be .35 person

So out final answer is 307

Find the volume of the given solid region in the first octant bounded by the plane 9z+15y+15z=45 and the coordinate planes, usi

dem82 [27]

First,

$9x+15y+15z=45\implies 3x+5y+5z=15$

The volume is given by the integral (one of 6 possible combinations),

$\displaystyle\int_0^5\int_0^{\frac{15-3x}5}\int_0^{\frac{15-3x-5y}5}\mathrm dz\,\mathrm dy\,\mathrm dx=\boxed{\frac{15}2}$
