Line AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4). Lines AB and CD are
vlada-n [284]

Answer  

Option (A) is correct .

Reason

The formula for the slope.

Slope = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

As given

Line AB contains (0, 4) and (1, 6) .

put in the slope formula

Slope = \frac{6 - 4}{1 - 0}

Slope = \frac{2}{1}

Slope of the AB is 2.

As given

Line CD contains points (2, 10) and (−1, 4).

put in the slope formula

Slope = \frac{4 - 10}{-1 -2}

Slope = \frac{-6}{-3}

Slope = 2

Slope of the CD is 2.

As the slope of the  AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (−1, 4) is 2 .

Therefore the option (A) is correct i.e the lines are parallel because the slopes are the same.

100 points!! Write and simplify a polynomial expression for the volume of each figure.
Nimfa-mama [501]

Answer:

See below

Step-by-step explanation:

1: (b+1)*(3b)*(b-5)

(3b^2+3b)(b-5)

3b^3-15b^2+3b^2-10b

3b^3-12b^2-10b

2: πr^  2(h/3)

π(n-2)^2(12n/3)

π(n-2)(n-2)(12n/3)

π(n^2-2n-2n+4)(12n/3)

π(n^2-4n+4)(12n/3)

π(n^2-4n+4)(4n)

π(4n^3-16n^2+16n)

<em>(I'm not 100% sure with this one)</em>

3: (lwh)/3

((k-2)(2k+3)(3k))/3

((2k^2-4k+3k-6)(3k))/3

(6k^3-12k^2+9k^2-18k)/3

(6k^3-3k^2-18k)/3

2k^3-k^2-6k

(P−2πr)

C)

x\approx173\text{ feet}x≈173 feet

Step-by-step explanation:

So, the track is composed of a rectangle and two semicircles.

The side length of the rectangle is x, and the radius of the semicircles is r.

Part A)

The perimeter is simply the length around the figure.

We can see that the perimeter will be equivalent to two times x plus two times the circumference of the semi-circles.
