Answer:

the second one

Step-by-step explanation:

in order for it to be a function the x values CANNOT repeat.

in answer a the x value -6 repeats so that cannot be a function

in answer b none of the x values repeat so its probably this one but lets check the other ones just in case

in answer c the x value 8 repeats so it cannot be this one

in answer d the x value -2 repeats so it cant be this one \

b is the only one that does have repeating x values therefore it is the second one

A line with a slope of 3 passes through the point (2, 4). What is the y-intercept of the line?

Answers

Answer:

y-intercept = -2

Step-by-step explanation:

Use the point-slope form of a line to do this problem.

[tex]y - y_{1} = m(x - x_{1})[/tex]

y - 4 = 3(x - 2)  Now change the equation to slope-intercept form

y - 4 = 3x -6

y = 3x - 2   So m = 3  b = y-intercept = -2

Two forces, one of 120 pounds and the other of 200 pounds, act on the same
object at angles of 30° and -30° respectively, with the positive x-axis. Find
the direction of the resultant of these two forces.

Answers

9514 1404 393

Answer:

  -8.21°

Step-by-step explanation:

The horizontal and vertical components of the forces are ...

  (120; 30°) = (103.923, 60}

  (200; -30°) = (173.205, -100}

Then the resultant is ...

  (103.923 +173.205, 60-100) = (277.128, -40)

and the resultant direction is

  arctan(-40/277.128) = -8.21°

_____

The polar coordinates (A; β) can be translated to rectangular coordinates by ...

  (A; β) = (A·cos(β), A·sin(β))

__

Additional comment

The semicolon in (A; β) signifies the ordered pair is polar coordinates (magnitude; angle). The comma in (x, y) signifies the ordered pair is rectangular (Cartesian) coordinates. This notation is borrowed from the GeoGebra app, a geometry graphing/calculating program. It avoids some confusion. Personally, I prefer the notation A∠β to signify a magnitude and direction in polar coordinates.

A force of 50N is applied to the end of a lever to lift a rock that is 350N. What is the MA of the lever? Is it actual or ideal?

Answers

Answer:

MA = 7, Actual

Step-by-step explanation:

Input force = 50N

Output force = 350N

MA = Output force / Input force

MA = 350 / 50 = 7

The difference between an ideal MA and an actual MA is that the former (ideal MA) uses distance while the latter (actual MA) uses force.

This is an Actual Mechanical Advantage

The MA of the lever will be "7" and it is actual.

According to the question,

Input force,

50 N

Output force,

350 N

As we know the formula,

→ [tex]MA = \frac{Out\ force}{Inp \ force}[/tex]

By substituting the values, we get

          [tex]= \frac{350}{50}[/tex]

          [tex]= 7[/tex]

Thus the above answer is correct as well as it is actual.

Work out the area of the rectangle using a calculator and
giving your answer as a mixed number.
2 2/7 cm
5 1/6 cm

Answers

Answer:

11 17/21 cm²

Step-by-step explanation:

Given

Length = 2 2/7cm

Width = 5 1/6cm

Area of the rectangle = Length * width

Area of the rectangle = 2 2/7 * 5 1/6

Area of the rectangle = 16/7 * 31/6

Area of the rectangle = (16*31)/(7*6)

Area of the rectangle  = 496/42

Area of the rectangle  = 11 34/42

Area of the rectangle  = 11 17/21

Hence the Area of the rectangle  is 11 17/21 cm²

A) [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

For this question, we can use the rise over run method, which means y over x.

So count how many it takes for the point on top to get to the bottom by x and y.

It takes 7 spaces down (y)  and 4 spaces to the right (x)

So do rise over run and we get

[tex]\frac{7}{4}[/tex]

Meaning that B and C are incorrect. Now what about A and D?

Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.

[tex]-\frac{7}{4}[/tex]

A. is correct.

Since they have the same slope and different y-intercepts , then there are no solutions for these equations because they're parallel.
