Find the slope of a line parallel to a line that contains the points (8, -3) and (2, 5).
Illusion [34]

Answer:

-\frac{4}{3}(Your answer choices were really confusing, so I just put the plain answer)

Step-by-step explanation:

To find the slope of a line with just two points, we can use the formula \frac{y2-y1}{x2-x1}. In this case, \frac{5-(-3)}{2-8}. This is \frac{8}{-6}. This reduces to -\frac{4}{3}

The angle between a 180-pound force F and AB= 5i + 2j is 30.Find the work done by F in moving and object from A to B.
Alexeev081 [22]

Answer:

W=839.464\ ft*lbf

Step-by-step explanation:

The work done is the product of the magnitude of the force applied to the object by the magnitude of the displacement of the object by the cosine of the angle between the force and direction of the displacement. This is:

W=|F|*|r|cos(\theta)

In this case

\theta=30\°

|F|=180 pound force

The magnitude of vector AB is:

|r|= \sqrt{5^2 + 2^2}\\\\|r|= \sqrt{29}\ fr

Finally the work is:

W=180*\sqrt{29}*cos(30\°)

W=839.464\ ft*lbf

You cannot take the square root of a negative number so the radicals must be greater than or equal to-1.

7.(2) You need to buy jars. They cost $14 per box, and you only have $150 to spend. How many
MakcuM [25]

Answer:

17 boxes

Step-by-step explanation:

Let x be the number of boxes that you can buy.

14x = 150

x = 250 / 14 = 17.85

We cannot buy 0.85 of a box, so we can only buy 17 boxes.
