Answer:

C. Each has a slope of –3, but one has a y-intercept of 3 and the other has a y-intercept of –1, which makes the lines parallel.

Step-by-step explanation:

Parallel lines will have no solution, since they share no points. To be parallel, they will have the same slope and different intercepts.

___

If the intercepts and slopes are the same, the lines are identical and there will be an infinite number of solutions.

The wind is blowing N 35.0 degrees W at 1.60 * 10^2 mph. A plane has an engine speed of 3.20 * 10^2 mph. Where should the pilot

Answer: 24.2° SouthWest

Step-by-step explanation:

First step: DRAW A PICTURE of the vectors from head to tail (see image)

I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.

Perpendicular (x):

cos 35° = adjacent/hypotenuse

cos 35° = x/160

→ x = 160 cos 35°

Angle (θ):

sin θ = opposite/hypotenuse

sin θ = x/320

sin θ = 160 cos 35°/320

θ = arcsin (160 cos 35°/320)

θ = 24.2°

Direction is down (south) and left (west)

The point (1,5) lies in quadrant II of a rectangular coordinate system

natali 33 [55]

Answer:

Step-by-step explanation:

Complex answer: For a point to be in quadrant II, it must have a negative x value and a positive y value.

Simple answer: The 1 would have to be negative to be in quadrant II, and it isn't

Bob and Carol are making glass dolls. On average, they break 12% of the dolls. Today, they only broke 2/3 as many dolls as usual

konstantin123 [22]

If you would like to know how many dolls did Bob and Carol break today, you can calculate this using the following steps:

On average, they break: 12% of 175 = 12/100 * 175 = 21 dolls.
Today: 2/3 as many dolls as usual = 2/3 * 21 = 14 dolls

Result: Bob and Carol broke 14 dolls today.
