Anna71 [15]

Answer:

x^2 +18x +80

= x^2 + 10x + 8x +80

= x(x+10) + 8(x+10)

= (x+10)(x+8)

Hope this help!

Good luck!

Find the distance between (-5, -8) and (-1, -16).

topjm [15]

To calculate the distance between two points, you have to use the distance formula.

point 1 is (-5, -8) and point 2 is (-1, -16). The x coordinate is before the comma and the y coordinate is after the comma.

The distance formula is:

Distance = $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }$

Insert your coordinates into the formula.

$\sqrt{((-1) - (-5))^{2} + ((-16) - (-8))^{2} }$

Combine your terms.

$\sqrt{(4)^2 + (-8)^2}$

Square your numbers.

$\sqrt{16 + 64}$

Add these terms together.

Your answer is $\sqrt{80}$ or 8.94

If A=(-1,1), B=(5,-2), C=(2,3), D=(a,5) and vector AB is parallel to vector DC, find the value of 'a'.

____ [38]

Answer:

a = 3

Step-by-step explanation:

$\vec{AB} = \\\vec{DC} = = \\\vec{AB} \perp \vec{DC} => \vec{AB} \cdot \vec{DC} = 0 = 6(2-a) + (-3)(-2) = 0\\12 - 6a + 6 = 0\\6a = 18\\a = 3$

two trains leave stations 280 miles apart at the same time and travel toward each other. one train travels at 95miles per hour w

katrin2010 [14]

Basiclaly, when will total distance equal distance they are apart
distance apart=280

distance=speed times time

assuming they travel sasme amount of time
time=t

distance=speed times time
d1=95 times t
d2=105 times t

total distance=d1+d2
280=d1+d2
280=95t+105t
280=200t
divide both sides by 200
1.4=t

answer is 1.4 hours or 84 mins
