Answer:

Choice C)

x^2 - 2x + 4 - 12/(x+2)

x^2 - 2x + 4 - \frac{12}{x+2}

====================================================

Explanation:

To see how I got that answer, I have provided two attached images below. One of them shows the polynomial long division. The other shows synthetic division. Both are valid options to get to the same answer.

For each method, I used 1x^3 + 0x^2 + 0x - 4 in place of x^3 - 4 so that the proper terms could align.

Find the area of shaded part .​
Firlakuza [10]

Answer:

Area of big rectangle= 5m× 3m

                                   = 15m²

Area of small rectangle=1m× 1m

                                       =1m²

Area of shaded part= Area of big rectangle- Area of a small rectangle

                                 = 15m²-1m²

                                  = 14m²

Step-by-step explanation: Hope it helps

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 9x2 y2 and the p
dolphi86 [110]

The vector function is, r(t) =  \bold{ < t,2t^2,9t^2+4t^4 > }

Given two surfaces for which the vector function corresponding to the intersection of the two need to be found.

First surface is the paraboloid, z=9x^2+y^2

Second equation is of the parabolic cylinder, y=2x^2

Now to find the intersection of these surfaces, we change these equations into its parametrical representations.

Let x = t

Then, from the equation of parabolic cylinder,  y=2t^2.

Now substituting x and y into the equation of the paraboloid, we get,

z=9t^2+(2t^2)^2 = 9t^2+4t^4

Now the vector function, r(t) = <x, y, z>

So r(t) = \bold{ < t,2t^2,9t^2+4t^4 > }

Suppose you inherited a house that was purchased in 1950 for 20,000. It is now 2015 and the value of the house has increased by
sleet_krkn [62]
This deals with exponential growth.
house value = 20,000 * (1.05)^years
(where years is # of years from 1950 - so 1950 = 0, 1951 = 1, etc)
house value = 20,000 * (1.05)^65
