Answer:

C. Rectangle and Cube

Step-by-step explanation:

It's actually pretty easy to figure this out because all you have to do is look at the shape, and try to find what to shapes made this figure. When you look at a cuboid (rectangular prism), you can see how the answer choices have one 2D shape, and one 3D shape. Well after looking at the Cuboid, we can see that there are rectangles on the faces, and this would be the 2D shape, and then we have a big cube holding those faces together, and the cube would be our 3D shape.

Hope this helps :)

Consider the polynomials p(x) = 3x + 27x^2 and q(x)= 2 . Find the x -coordinate(s) of the point(s) of intersection of these two
Tom [10]

Answer:

The x -coordinate(s) of the point(s) of intersection of these two polynomials are x=\frac{2}{9}\approx0.2222,\:x=-\frac{1}{3}\approx-0.3333

The sum of these x -coordinates is \frac{2}{9}+\left(-\frac{1}{3}\right)=-\frac{1}{9}

Step-by-step explanation:

The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).

Thus, 3x + 27x^2=2 and we solve for x

3x+27x^2-2=2-2\\27x^2+3x-2=0\\\left(27x^2-6x\right)+\left(9x-2\right)\\3x\left(9x-2\right)+\left(9x-2\right)\\\left(9x-2\right)\left(3x+1\right)=0

Using Zero Factor Theorem: = 0 if and only if = 0 or = 0

9x-2=0\\9x=2\\x=\frac{2}{9}

3x+1=0\\3x=-1\\x=-\frac{1}{3}

The solutions are:

x=\frac{2}{9}\approx0.2222,\:x=-\frac{1}{3}\approx-0.3333

The sum of these x -coordinates is

\frac{2}{9}+\left(-\frac{1}{3}\right)=-\frac{1}{9}

We can check our work with the graph of the two polynomials.

Which set of steps will translate f(x)=6x to g(x) =6x-5-7?
BaLLatris [955]

Answer:

vertical translation of 5 units in the negative y direction, followed by a vertical translation of 7 units in the negative y direction.

Step-by-step explanation:

given f(x)=6x

f(x)=6x ---> f(x)=6x - 5    (Vertical translation by 5 units in the negative y (i.e downward) direction)

f(x)=6x - 5 ---> f(x)=6x - 5  - 7 (Vertical translation by 7 units in the negative y (i.e downward) direction)

hence it is a vertical translation of 5 units in the negative y direction, followed by a vertical translation of 7 units in the negative y direction.
