Answer: ||q_{A}||=5, ||q_{B}||= 3, ||q_{C}|| = 0.

Step-by-step explanation:

The magnitude is an absolute value by definition. Hence, each element has the respective value:

||q_{A}|| = 5\\||q_{B}|| = 3\\||q_{C}|| = 0\\

Find the equation of the line passing through the point (1,−5) and perpendicular to y=18x+2
sleet_krkn [62]

Step-by-step explanation:

m1.m2 = -1

18.m2 = -1

m2 = -1/18

formula = y - y1 = m2 ( x - x1)

y - (-5) = -1/18 ( x -1)

y + 5= -1x/18 +1/18

y = -1x/18 -89/18

If a truck averages 12 miles to the gallon, how many pounds of carbon dioxide are emitted into the atmosphere when the truck tra
77julia77 [94]

Answer: 278.30 pounds (if the gasoline does not contain ethanol)

317.12 pounds (if the gasoline does contain ethanol)

Step-by-step explanation:

If the truck averages 12 miles per gallon, then in 170 miles it consumes:

170mi/12mi = 14.17 gallons.

We know that for one gallon consumed, the carbon dioxide emitted into the atmosphere is 19.64 pounds. (assuming it does not contain ethanol)

Then for 14.17 gallons consumed, we have a emission of:

14.17*19.64 pounds = 278.30 pounds

I the gasoline contains ethanlol, for a gallon the emiision is around  22.38 pounds.

In this case the total emission is:

14.17*22.38 pounds = 317.12 pounds

5. Solve the equation. 8/x+3 = 1/x+1
Helga [31]

Answer:

x = -5/7

Step-by-step explanation:

8               1

---------- = ----------

x+3           x+1

Using cross products

8 (x+1) = 1 (x+3)

Distribute

8x+8 = x+3

Subtract x from each side

8x-x +8 = x-x+3

7x+8 =3

Subtract 8 from each side

7x +8-8 =3-8

7x = -5

Divide each side by 7

7x/7 = -5/7

x = -5/7
