Tell whether the lines through the given points are parallel, perpendicular, or neither. (-3,1), (-7,-2), (2,-1), (8,4)

Answers

Answer 1

Answer:

neither

Step-by-step explanation:

(-3,1), (-7,-2)

Slope of the line containing point (-3,1), (-7,-2) is

[tex]slope = \frac{y_2-y_1}{x_2-x_1} =\frac{-2-1}{-7+3} =\frac{3}{4}[/tex]

Slope of the line containing point (2,-1), (8,4) is

[tex]slope = \frac{y_2-y_1}{x_2-x_1} =\frac{4+1}{8-2} =\frac{5}{6}[/tex]

Slope of both the lines are not same, so they are not parallel

the slope of both the lines are not negative reciprocal of one another

So they are not perpendicular

Hence they are neither parallel nor perpendicular.

1/4 + 1/8= I know it should be easy but my teacher told me that we can't add fractions if they have different denominators. Now if you are going to explain the to me I am in 5th grade so please don't make it to complicated.Thank you.

Answers

1/4 + 1/8= 3/8
Remember you need a common denominator so 4*2 is 8 and you multiply the numerator by 2 to get 2/8. Which makes the problem 2/8+1/8=3/8
Alright, this is my first question I’ve answered so excuse me.

When adding fractions, it’s easier to ask yourself how you can get the denominators to be the same. In this case, 1/4 can also be 2/8, if we multiply 1/4 by 2/2. 1x2 is 2 and 4x2 is 8. 1/4 and 2/8 are the same because 2/2 can also be written as 1, and 1 times anything gives the same answer.

Now we have 1/8 + 2/8, which would be 3/8.

In an arcade game, a 0.13 kg disk is shot across a frictionless horizontal surface by being compressed against a spring and then released. The spring has a spring constant of 242 N/m and is compressed from its equilibrium position by 5.2 cm. What is the magnitude of the spring force on the disk at the moment it is released?

Answers

Answer:

12.584 N

Step-by-step explanation:

To solve this problem you need to use Hokke's law, this is a physics lar which states the force (F) you need to compress a spring for some distance (x) can be easily calculated with the equation F=kx. The constant k (the stiffness of the spring) is the value of 242 N/m and x is the distance 5.2 cm = 0.052 m. So if you multiply 242 N/m by 0.052 m you will obtain 12.584 N, which is the necessary force to compress the spring 5.2 cm. The mass of the spring is a nonrelevant data in this problem.

Raina is putting 13 colored light bulbs into a string of lights. There are 5 white light bulbs, 6 orange light bulbs, and 2 blue light bulbs. How many distinct orders of light bulbs are there if two light bulbs of the same color are considered identical (not distinct)?

Answers

Answer: The number of ways would be 36,036.

Step-by-step explanation:

Since we have given that

Number of white light bulbs = 5

Number of orange light bulbs = 6

Number of blue light bulbs = 2

Total number of light bulbs = 13

So, the number of distinct orders of light bulbs if two bulbs of the same color are considered identical.

[tex]N=\dfrac{n!}{r!}\\\\N=\dfrac{13!}{5!\times 6!\times 2!}\\\\N=36036[/tex]

Hence, the number of ways would be 36,036.

Final answer:

The number of different orders in which Raina can put the colored light bulbs into a string is 1,324, calculated using the formula of permutations with indistinguishable items.

Explanation:

The question is about the number of different possible arrangements, or combinations, of the colored light bulbs. Since all light bulbs of the same color are identical, this is a problem of permutations with indistinguishable items. The formula to calculate this is n!/(r1!*r2!*...*rn!), where n is the total number of items, and r1, r2,...,rn are the number of each type of identical items.

So in this case, there are 13 colored light bulbs in total (n=13), with 5 white light bulbs (r1=5), 6 orange light bulbs (r2=6), and 2 blue light bulbs (r3=2).

The total different orders of light bulbs can be found by calculating 13!/(5!*6!*2!) = 1,324 possibilities.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes was 5 and no votes was 7.
If there were 3710 yes votes, what was the total number of votes?

Answers

Answer:

Step-by-step explanation:

Set this up as a proportion.  The idea is that if we can find out the number of "no" votes based on the ratio of 5:7, then we can add the "no" votes to the number of "yes" votes to get the total number of votes.

[tex]\frac{yes}{no}:\frac{5}{7}=\frac{3710}{x}[/tex]

Cross multiply to get

5x = 25790 so

x = 5194 "no" votes.

5194 + 3710 = 8904 total votes

Sketch the graph of the given function. Then state the function’s domain and range. f(x)= 1/2(5)^x+3

Keys went to the grocery store on Monday and bought 5 apples and 2 oranges for a total of 3.45. On Thursday she bought 3 oranges and 7 apples for a total of $4.90

Answers

Answer:

Keys would have to spend $6.60 on apples for both days.

Step-by-step explanation:

Keys went to buy 5 apples and 2 oranges for $3.45 and 7 apples and 3 oranges for $4.90 .

We have to find how much money she spends on apples on both the days.

Let price of apples be x and oranges be y.

We have to make equations and solve them to find the price of oranges and apples.

5x + 2y = 3.45

7x + 3y = 4.90

Solve both these equations to find x and y.

We get x= $0.55 and y = $0.35

A 20 kg sphere is at the origin and a 10 kg sphere is at x = 20 cm. At what position on the x-axis could you place a small mass such that the net gravitational force on it due to the spheres is zero?

Answers

The small mass should be placed at x = 11.72 cm or x = 68.28 cm

Step-by-step explanation:

Let the small mass be m and position on x axis be y.

A 20 kg sphere is at the origin.

Distance to 20 kg mass = y

A 10 kg sphere is at x = 20 cm

Distance to 10 kg sphere = 20 - y

We have gravitational force

                      M = Mass of body 1

                      M = Mass of body 2

                      r = Distance between them

Here we have

            [tex]\frac{G\times 20\times m}{y^2}=\frac{G\times 10\times m}{(20-y)^2}\\\\800-80y+2y^2=y^2\\\\y^2-80y+800=0\\\\y=68.28cm\texttt{ or }y=11.72cm[/tex]

So the small mass should be placed at x = 11.72 cm or x = 68.28 cm

The positions on the x-axis obtained using quadratic equation such that net gravitational force is zero are 68.28 and 11.72 cm respectively.

Recall the force of universal gravitational attraction :

[tex] \frac{Gm_{1}m_{2}}{r^{2}}[/tex]

Sphere 1 :

Mass = 20 kg Distance of 20kg sphere = d

Sphere 2 :

Mass = 10kgDistance of 10kg sphere = 20 - d

Gravitational force ; sphere 1 :

[tex] \frac{G \times 20 \times m_{2}}{d^{2}}[/tex] --(1)

Gravitational force ; sphere 2 :

[tex] \frac{G \times 10 \times m_{2}}{(20 - d)^{2}}[/tex] - - (2)

Equate (1) and (2)

[tex] \frac{G \times 20 \times m_{2}}{d^{2}} = \frac{G \times 10 \times m_{2}}{(20 - d)^{2}} [/tex]

[tex] 20(20 - d)^{2} = 10 \times d^{2} [tex]

20(400 - 40d + d²) = 10d²

8000 - 800d + 20d² = 10d²

10d² - 800d + 8000 = 0

Divide through by 10

d² - 80d + 800 = 0

Answers

Answer:210

Step-by-step explanation:

175+70+15=210

Answer:the original price is $210

Step-by-step explanation:

Let x represent the original price of the tent. She bought it at price that is $70 off the original price. This means that $70 was taken off the original price.The amount after the discount has been removed would be

x - 70

Judy also used a coupon for an extra $15 off. This means that the amount the Judy finally paid for the tent would be

x - 70 - 15

if Judy paid $125 for the tent, it means that

x - 70 - 15 = 125

x = 125 + 70 + 15

----
I know I have asked this before but people have given me only one answer, which was C but I think I need to select more than one answer. Thanks so much for any help.

Answers

Answer:

Option B) and option D) are independent events. i.e. following events are independent events:

B) A coin is flipped and a spinner is spunD) Four number cubes are rolled at the same time.

Step-by-step explanation:

Two events would be termed as Independent events if the occurrence of one event would not affect the occurrence of other event.

Let us first consider the options having independent events.

B) A coin is flipped and a spinner is spunD) Four number cubes are rolled at the same time.

Option B) i.e. 'a coin is flipped and a spinner is spun' is treated as neither of the events is affecting the outcome of other event. For example, assuming a coin and spinner are kept isolated, the occurrence of event of a flipping coin is not affecting the outcome of the occurrence of spinner.

The same goes with the option D) i.e. 'four number cubes are rolled at the same time', as neither of the rolling is affecting the rolling of other coin.

Now, let us consider the options having dependent events

A) One ball is drawn from a bag of balls after another ball is drawn without replacement.C) White marbles are drawn from a bag of marbles without replacing the marbles.

Let us suppose one ball is drawn from a bag of balls after another ball is drawn without replacement. If there is no replacement, it logically means, after every drawn event, total number of the balls are getting decreased, hence, bringing a variation among the probability after every event, as the occurrence of next event would be dealing with the remaining of the data, instead of the data that was present before the drawn of first event. Hence, the occurrence of every event depends upon the occurrence of other event, meaning the two events will keep affecting the outcome if no replacement is made before the next event.

The same logic goes with when white marbles are drawn from a bag of marbles without replacing the marbles. If there is no replacement, it logically means, after every drawn event, total number of the white marbles and marbles are getting decreased, hence, bringing a variation among the probability after every event, as the occurrence of next event would be dealing with the remaining of the data, instead of the data that was present before the drawn of first event.

So, after all the discussion, we can safely say make a conclusion that option B) and option D) are independent events. i.e. following events are independent events:

B) A coin is flipped and a spinner is spunD) Four number cubes are rolled at the same time.

2. Jenna Ford purchased a compact stereo that regularly sells for $229.99 at a markdown rate of 53%. In California, where Jenna lives, the sales tax rate on this item is 7%. Find the final price of the item.

Answers

Answer:

$115.67

Step-by-step explanation:

given that the markdown rate is 53%, that means that the markdown is 53% of the original price, or,

markdown = 53% of $229.99 = 0.53 x 229.99 = $121.89

sale price before tax = Original Price - Markdown

= 229.99 - 121.89

= $108.10

sales tax = 7% of sale price before tax

= 0.07 x 108.10

= $7.57

Final price =  price before tax + tax

= 108.1 + 7.57

= $115.67

3(5j+2)=2(3j-6)(if there is no solution,type in ''no solution'')j= Answer

Answers

Answer:

  j = -2

Step-by-step explanation:

It usually works well to start by eliminating parentheses.

  15j +6 = 6j -12

Now you can subtract 6j from both sides to get the variable term on one side of the equation only:

  9j +6 = -12

And you can subtract 6 from both sides to get the variable term by itself:

  9j = -18

Now, dividing by the coefficient of the variable gives you the solution:

  j = -2

The solution is j = -2.

Answer:

j = -2

Step-by-step explanation:

3 (5j + 2) = 2 (3j - 6)

15j + 6 = 6j - 12

15j - 6j = - 12 - 6

9j = - 18

j = - 18/9

j = - 2

Prove that if f is one-to-one, then f(X) ∩ f(Y ) = f(X ∩ Y ) for all X, Y ⊆ A. Is the converse true?

Answers

Answer:

See proof below, the converse is true

Step-by-step explanation:

Let f be a function whose domain is the set A, and X,Y be arbitrary subsets of A. One way to prove the equality of sets f(X)∩f(Y)=f(X∩Y) is, by definition, to prove the inclusions f(X)∩f(Y) ⊆ f(X∩Y)  and f(X)∩f(Y )⊇f(X∩Y).

First, let a∈f(X)∩f(Y). Then a∈f(X) and a∈f(Y) by definition of intersection. Thus, a=f(t) for some t∈X (because a is an element of the direct image of X) and a=f(s) for some s∈Y. Then a=f(t)=f(s). We know that f is 1-1, so the previous equality implies that t=s. Now, t∈X and t=s∈Y, thus t∈X∩Y. Therefore, a=f(t) for some t∈X∩Y, which means that a is an element of the direct image of X∩Y, that is, a∈f(X∩Y). This holds for all a, thus f(X)∩f(Y) ⊆ f(X∩Y).

For the second inclusion, let b∈f(X∩Y), then there exists some z∈X∩Y such that b=f(z). Since z∈X∩Y, we have that z∈X and z∈Y. Thus, b=f(z) for some z∈X, that is, b∈f(X). Similarly, b∈f(Y) because b=f(z) and z∈Y. Therefore b∈f(X)∩f(Y) for all  b∈f(X∩Y), then f(X)∩f(Y )⊇f(X∩Y). Note that this holds for any function f, as we did not use that f is 1-1.

To prove the converse, suppose that f(X)∩f(Y)=f(X∩Y)  for all  X, Y⊆ A. We will prove that f is 1-1, that is, for all a,b∈A if f(a)=f(b) then a=b.

Define the sets X:={a} and Y:={b}. Then f(X)={f(a)} and f(Y)={f(b)}. Assuming that f(a)=f(b), we obtain f(X)=f(Y). We know that f(X)∩f(Y)=f(X∩Y), which means {f(a)}=f(X∩Y). Then, there exists some s∈X∩Y such that f(s)=f(a), thus X∩Y is a non-empty set, which implies that a∈Y. But Y has only one element, b, therefore a=b which shows that f is 1-1.

Can someone please write the equation of hyperbola with vertices (0, -5) and (0, 5) and co-vertices (-2, 0) and (2, 0)?

Thank you so much!

Answers

Answer:

  y^2/25 -x^2/4 = 1

Step-by-step explanation:

The equation can be written as ...

  y^2/a^2 -x^2/b^2 = 1

where the vertices are at (0, ±a) and the co-vertices are at (±b, 0). Filling in the given values (a=5, b=2) gives the equation shown above.

Answers

Answer:

Part 1) Intervals of the domain where the  graph is above the x-axis (f(x) > 0)

Part 2) location on graph where input is zero  (y-intercept)

Part 3) location on graph where output is zero  (x-intercept)

Part 4) Intervals of the domain where the  graph is below the x-axis (f(x) < 0)

Step-by-step explanation:

Verify each case

Part 1) we have

Intervals of the domain where the  graph is above the x-axis

we know that

If the graph is above the x-axis, then the value of f(x) is positive

therefore

f(x) > 0

Part 2) we have

location on graph where input is zero  

Let

x ---> the independent variable or input value

f(x) ---> the dependent variable or output value

we know that

The y-intercept is the value of f(x) (output value) when the value of x (input value) is zero

therefore

y-intercept

Part 3) we have

location on graph where output is zero  

Let

x ---> the independent variable or input value

f(x) ---> the dependent variable or output value

we know that

The x-intercept is the value of x (input value) when the value of the function f(x) (output value) is zero

therefore

x-intercept

Part 4) we have

Intervals of the domain where the  graph is below the x-axis

we know that

If the graph is below the x-axis, then the value of f(x) is negative

therefore

f(x) < 0

Answer:

Intervals of the domain where the  graph is above the x-axis (f(x) > 0)

location on graph where input is zero  (y-intercept)

location on graph where output is zero  (x-intercept)

Intervals of the domain where the  graph is below the x-axis (f(x) < 0)
