11. The slope and y-intercept for each linear equation include:

y = 2x + 3     slope = 2   y-intercept = 3

y = -1/2(x) + 1     slope = -1/2   y-intercept = 1

The lines are perpendicular.

12. 4y = 8x - 2     slope = 2   y-intercept = -2

-4x + 2y = -1     slope = 2   y-intercept = -1/2

The lines are parallel.

What is the slope-intercept form?

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

m represent the slope or rate of change.x and y are the points.b represent the y-intercept or initial value.

Question 11.

Based on the information provided above, we have the following linear equation;

y = mx + b

y = 2x + 3          ⇒ slope = 2   y-intercept = 3

y = -1/2(x) + 1   ⇒   slope = -1/2   y-intercept = 1

For perpendicular lines, we have:

m₁ × m₂ = -1

2 × m₂ = -1

m₂ = -1/2

Question 12.

Based on the information provided above, we have the following linear equation;

y = mx + b

4y = 8x - 2  ≡ y = 2x - 1/2    slope = 2   y-intercept = -1/2

-4x + 2y = -1  ≡ y = 2x - 1/2   slope = 2   y-intercept = -1/2

m₁ = m₂ = 2.

Therefore, the lines are parallel.

quadrilateral $abcd$ is a square. let $a,$ $b,$ $c$ be parallel lines passing through $a$, $b$, $c$, respectively. the distance between lines $a$ and $b$ is $12,$ and the distance between lines $b$ and $c$ is $17$. find the area of square $abcd$.

Answers

The area of square abcd is  be parallel lines passing through $a$, $b$, $c$, respectively is the 433.

Squares are quadrilaterals with four congruent aspects and four proper angles, and additionally they have units of parallel aspects. Parallelograms are quadrilaterals with units of parallel aspects. Since squares have to be quadrilaterals with units of parallel aspects, then all squares are parallelograms.

Here we have the values the distance between lines a and b is 12, and the distance between lines b and c is 17.

The distance is 12 and 17

x^2 = 12^2 + 17^2 = 144 +289 = 433

433 is the total that is the area of square of abcd.

Thus the area = 433.

Step-by-step explanation:

Roland hires a mechanic to do some work. He pays y dollars per hour for a 3-hour job plus $48 in replacement parts. The total cost comes to $200. Please round to the nearest cent.

Create an equation that can be used to find the amount, in dollars, the mechanic charges per hour.

Answers

So, the variable here is y: the amount of dollars per hour of work. We already know how many hours (3), the additional costs (48), and the total cost (200). What we need to do is put this into an equation. So we have number of hours times hourly rate plus additional costs:
3y + 48 = 200

In order to solve for y, this is what you have to do:
3y + 48 = 200 (subtract 48 from both sides)
3y = 152 (divide by 3 on both sides)
y = 50.666666
round to the nearest cent and you’d get a final answer of:

Let f(x)= 6x +\sqrt{(x+37)} Choose the form of the largest interval on which f has an inverse...

Answers

The domain of f is the interval [-37, ∞).

For a function to have an inverse, it must be one-to-one, which means that it must pass the horizontal line test, i.e., each horizontal line should intersect the graph of the function at most once.

The derivative of the function is:

\(f'(x) = 6 + (1/2√(x+37))\)

f'(x) is always positive because 6 is positive and the square root is positive, so f(x) is an increasing function. This means that f(x) is one-to-one and therefore has an inverse.

To determine the largest interval on which f has an inverse, we need to find the domain of f. The square root can only take non-negative values, so we must have x+37 ≥ 0, which means x ≥ -37.

Therefore, the domain of f is the interval [-37, ∞).

Since f is increasing over this interval, its inverse will also be increasing, and the largest interval on which f has an inverse is [-37, ∞).

The proper question is "Let f(x)=6x+√(x+37)Choose the form of the largest interval on which f has an inverse and enter the value(s) of the endpoint(s) in the appropriate blanks. Then find (f−1)′(0)

a cube has edge length 4 inches. a. find the surface area and volume of the cube. surface area square inches volume cubic inches b. the cube is dilated by a scale factor of 0.25. find the surface area and volume of the image. surface area square inches volume cubic inches

Answers

The surface area and volume of a cube with different edge length are

When a cube with edge length 4inches ,

Surface area = 96 square inches and Volume =64 cubic inches.

Cube dilated by scale factor 0.25 ,  

Surface area = 6 square inches and Volume =1 cubic inches.

The surface area of a cube is = 6 times the area of one face.

Each face of this cube has an area equals to

= (4 inches) x (4 inches)

= 16 square inches,

So the total surface area is,

Surface area

= 6 x 16 square inches

= 96 square inches

The volume of a cube =  length of one edge cubed.

Here, the edge length is 4 inches,

Volume

= (4 inches)^3

= 64 cubic inches

When a cube is dilated by a scale factor of 0.25, all of its edges are multiplied by 0.25.

This implies,

The edge length of the image cube is

0.25 x 4 inches = 1 inch.

Surface area of the image cube =  6 times the area of one face.

Each face of the image cube has an area of

= (1 inch) x (1 inch)

= 1 square inch,

So the total surface area is,

Surface area

= 6 x 1 square inch

= 6 square inches

Volume of the image cube = length of one edge cubed.

Here, the edge length is 1 inch,

Volume

= (1 inch)^3

= 1 cubic inch

Therefore, the surface area and volume for the given dimensions are

For edge length 4inches , Surface area = 96 square inches and Volume =64 cubic inches.

For scale factor 0.25 ,  Surface area = 6 square inches and Volume =1 cubic inches.

Sasha is playing a game with two friends. Using the spinner pictured, one friend spun a one, and the other friend spun a four. Sasha needs to spin a number higher than both friends in order to win the game, and she wants to calculate her probability of winning. How many desired outcomes should Sasha use in her probability calculation

Answers

Sasha should use 2 desired outcomes in her probability calculation to determine that she has a 1/3 chance of winning the game.

To calculate Sasha's probability of winning, we need to determine how many desired outcomes she has. In this game, Sasha needs to spin a number higher than both of her friends' spins, which means she needs to spin a number greater than 1 and 4.

Let's analyze the spinner pictured. From the image, we can see that the spinner has numbers ranging from 1 to 6. Since Sasha needs to spin a number higher than 4, she has two options: 5 or 6.

Now, let's consider the desired outcomes. Sasha has two desired outcomes, which are spinning a 5 or spinning a 6. If she spins either of these numbers, she will have a number higher than both of her friends and win the game.

To calculate Sasha's probability of winning, we need to divide the number of desired outcomes by the total number of possible outcomes. In this case, the total number of possible outcomes is the number of sections on the spinner, which is 6.

Sasha's probability of winning is 2 desired outcomes divided by 6 total outcomes, which simplifies to 1/3.

a company makes widgets from three machines. machine m1 makes 3000/hour, and 80% are good. machine m2 makes 4000/hour, and 90% are good. machine m3 makes 3000/hour, and 60% are good. all widgets are mixed together. what is the probability that a widget drawn at random is good

Answers

If all the widgets from the three machines are mixed together, then the probability that a good widget will be drawn at random is 0.78 or 78%.

Probability is defined as how likely an event is to occur, or how likely it is that a proposition is true.

If machine 1 makes 3000/hour and 80% are good, then the chances of it being good is 80% also or, 2400 out of 3000.

80% of 3000 is 2400

If machine 2 makes 4000/hour and 90% are good, then the chances of it being good is 90% also or, 3600 out of 4000.

90% of 4000 is 3600

If machine 3 makes 3000/hour and 60% are good, then the chances of it being good is 60% also or, 1800 out of 3000.

60% of 3000 is 1800

Mixing together the widgets from the three machines, use the formula to calculate the probability of an event which is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Probability(good) = (2400 + 3600 + 1800)/(3000 + 4000 + 3000)

Probability(good) = 7800/10000

Probability(good) = 0.78 or 78%

Hence, the probability that a good widget drawn at random is 0.78 or 78%.

The amount of Interest Tristan pays is $955.2

Given:

Tristan borrows $4000 at an interest rate of 7.4% with a loan term of 3 years.

we are asked to determine the interest Tristan pays for it:

we know:

P = $4000

r = 7.4%

t = 3 years.

Evaluate :

I = 4000(1+7.4%)³ - 4000

I = 4000(1+0.074)³ - 4000

I = 4000(1.074)³ - 4000

I = 4000(1.2388) - 4000

I = 4955.2 - 4000

I = 955.2

The probability of rolling dice twice

What is Probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Total no. of outcomes = 6

The probability of getting a 1,2 or 3 from the first rolling is 3/6.

The probability of getting a 5 or 6 from second rolling is 2/6

As the two rollings are independent,

you can just multiply two probability values to come up with a final answer.

Which is,

             = (3/6) x (2/6)

             = (1/2) x (1/3)

             = (1/6)

The probability a rolling a 1, 2 or 3 on a number cube on your first roll, then a 5 or 6 the second roll is 1/6 or 0.16

Probability in % will be

                                   0.16 x  100/100

                                        = 16%

A piece of raw silk that is 100 yards long by 1.25 yards wide weights 38lb.

Then, a piece that is 12.5 yards long (and still 1.25 yards wide) will weight:

M = (12.5/100)*38lb = 4.75 lb

And a piece of habotai silk that is 100 yards long by 1.25 yards wide weights 12lb.

Then, a piece that is 12.5 yards long will weigh:

M' = (12.5/100)*12lb = 1.5 lb
