B. 2u - 6 R 11

C. 2u + 6 R 11

Answers

Answer 1

Answer: (2u² - 7) ÷ (u + 3)

2u² + 0u - 7 ÷ u + 3
2u - 6
u + 3 I 2u² + 0u - 7
- 2u² + 6u
0 - 6u - 7
+ - 6u - 18
0 + 11

Answer is: B. 2u - 6 R 11

Directed line segment porque is shown on the coordinate plane. What are the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1)?

Answers

Answer: (2,3).

Step-by-step explanation:

We need to find the coordinates of the point 1/3 of the way from point P(4,4) to point Q(-2,1).

Let the point be A.

$PA:PQ=1:3$

$PA:AQ=PA:(PQ-PA)=1:(3-1)=1:2$

It means the point A divide the segment PQ in 1:2.

Section formula: If a point divide a segment is m:n.

$\left((mx_2+nx_1)/(m+n),(my_2+ny_1)/(m+n)\right)$

$A=\left((1(-2)+2(4))/(1+2),(1(1)+2(4))/(1+2)\right)$

$A=\left((-2+8)/(3),(1+8)/(3)\right)$

$A=\left((6)/(3),(9)/(3)\right)$

$A=\left(2,3\right)$

Therefore, the required coordinates are (2,3).

If a roof's slope is 0.5, how high will the roof rise over a 17-foot run?a). 8 1/2 feet
b). 17feet
c). 1/34 feet
d). 34 feet

Answers

The answer to the mathematics question presented above would be letter a) 8 and 1/2 feet. If a roof's slope is 0.5, the height of the rise of the roof over a 17 foot run would be 8 and 1/2 feet. I got this answer through multiplying the slope and the run to get the rise.

Answer a) 8 and half feet.

You calculate it in this way

slope = rise / run ⇒ rise = slope * run = 0.5 * 17 feet = 8.5 feet.
