state the vertices, foci, and asymptotes of the hyperbola with the equation
20x^2-25y^2=100
PLEASE SHOW YOUR WORK SO I CAN UDERSTAND!!!

Answers

Answer 1
To find the vertices, foci, and asymptotes of the hyperbola with equation 20x^2 - 25y^2 = 100, we need to first write the equation in standard form:

(x^2)/(5) - (y^2)/(4) = 1

From this equation, we can see that the hyperbola has a horizontal transverse axis, since the x^2 term is positive and is divided by a smaller number than the y^2 term. Therefore, the center of the hyperbola is (0,0).

Using the standard form of the hyperbola, we can find the values of a and b:

a^2 = 5, so a = sqrt(5)
b^2 = 4, so b = 2

Now we can find the vertices, foci, and asymptotes:

Vertices:
The vertices are located at (±a,0), so the vertices are at (-sqrt(5),0) and (sqrt(5),0).

Foci:
The foci are located at (±c,0), where c = sqrt(a^2 + b^2). Plugging in our values of a and b, we get:

c = sqrt(5+4) = sqrt(9) = 3

So the foci are at (-3,0) and (3,0).

Asymptotes:
The equations of the asymptotes are y = ±(b/a)x, so the equations of the asymptotes are:

y = ±(2/sqrt(5))x

Therefore, the vertices are (-sqrt(5),0) and (sqrt(5),0), the foci are (-3,0) and (3,0), and the equations of the asymptotes are y = ±(2/sqrt(5))x.

(B) What is the problability of getting a number less than 3 on the die and a number greater than 5 on the spinner?

Answers

Answer:

(A) P(5 on die) = 1/6, P(7 on spinner) = 1/8

(1/6)(1/8) = 1/48

(B) P(less than 3 on die) = 2/6 = 1/3

P(greater than 5 on spinner) = 3/8

The table shows the snacks in Melissa's pantry.What is the probability that she chooses a fruit snack, puts it back, and then chooses a granola bar? This problem is based on Independent event problems.

Answers

Answer:

5/36

Step-by-step explanation:

The chance that Melissa chooses a fruit snack is 5/12. This is because there are 5 fruit snacks and 12 snacks in total. If she puts the fruit snack back, the chance of getting a granola bar is 4/12 or 1/3 because there are 4 granola bars and 12 snacks in total making it 4/12 and when simplified, 1/3. You must then multiply the fractions. After multiplying 5/12 by 1/3, you get 5/36.

Answer:

The correct answer is the one on the bottom. The other answers shown are all wrong. The correct answer is J

Step-by-step explanation:

First off, you have to figure out what's the unit rate, so we come across two points, in this case, I came up with the orgin and (10, 2). We did the rise over the run, which gave us a unit rate of 5 of y for every x. In this case, the correct answer would be H. Even though I can't see what H is, every single other one is correct, so we have to come to the conclusion that H is the correct choice for the one that's wrong.

F matches with the unit rate since 2/10 is also equaled to 0.2/1 since it's 0.2 per piece, so the piece is the x and the 0.2 is the y.

G matches with the unit rate because it's 6 workers per 30 children. 6/30 matches with 2/10.

H matches with the unit rate since it's 9 pages per 45 minutes, making the equation 9/45, which indeed, does match 2/10.

J doesn't match with the unit rate since 10 dollars per 2 hours implies that the equation is 10/2, which gives you the unit rate of 5/1 or 5, which is the reciprocal of 1/5.

Answer:

  J.  Richie earns $10 every 2 hours to pet sit for his neighbor

Step-by-step explanation:

You want to identify the situation with the different unit rate.

Unit rate

For proportional relations, such as the ones given in this problem, the unit rate is calculated by dividing a value for the dependent variable by the corresponding value for the independent variable. When the coordinates are expressed as an ordered pair (x, y), the unit rate is y/x.

Graph

The graph passes through a couple of grid intersections. One of them has coordinates (10, 2). The unit rate is 2/10 = 0.2.

F Gum

The unit rate is the rate for 1 unit: $0.20 for 1 piece. The numerical value of the unit rate is 0.20, same as the graph.

G Daycare

The given relation between children and workers is (children, workers) = (30, 6). The unit rate is 6/30 = 0.2, same as the graph.

H Reading

The relation between minutes and pages is (minutes, page) = (45, 9). The unit rate is 9/45 = 0.2, same as the graph.

J Earnings

The relation between hours and earnings is (hours, earnings) = (2, 10). The unit rate is 10/2 = 5, different from the graph.

The different unit rate is ...

 J.  Richie earns $10 every 2 hours to pet sit for his neighbor

__

Additional comment

Calculating the unit rate as y/x only works when the relation is a proportional one. All of the situations here have proportional relations.

Answer:

The correct answer is B.

Step-by-step explanation:

First off, if you don't already know what's the vertical line test, you're guaranteed to get this question wrong.

The vertical line test is a visual way to figure out if the function is a function. You just draw a line anywhere on the paper, and see if it intersects on one point or more than one point. If it intersects at only one point, it's a function because at the end of the day, you can have only one output for each input.

Think of this as an actual function. For example, if you go to a vending machine, and you put a dollar in for a single bag of chips, the next time you put a dollar in, you should get only one bag of chips, or else the machine is broken. It won't function.

In this case, it's a function since each input has its own output, or it passes the vertical line test, it's good to go. It's not a linear function since it's not straight, but hey, it at least is a function.

The correct answer is B!

The volume of a cone with a height of 10 meters is 20π cubic meters. What is the diameter of the cone?

Please give an explanation. Will give brainliest.

Answers

Answer:

The diameter of the cone is 2[tex]\sqrt{6}[/tex] or [tex]\sqrt{24}[/tex]

Step-by-step explanation:

The volume of the cone formula is 1/3hπr².

We already are given the volume and the height, so we can plug those in.

Our formula to find the radius is this: 20π=1/3(10)πr².

Since we have π on both sides, cancel the π on both sides.

We are left with 20=1/3(10)r².

We move 1/3 to the other side, so then we get 60=10r².

We then divide 10 on both sides, so we get 6=r².

Square root both sides to find out the radius.

The result we get is [tex]\sqrt{6}[/tex]=r.

But, we're not done yet.

Diameter=double the radius.

Multiply this radius by 2, and we'll get 2[tex]\sqrt{6}[/tex], or [tex]\sqrt{24}[/tex].

What is 24d + 0.2 = 29.6

Answers

Answer:

d=1.225

Step-by-step explanation:

24d+0.2=29.6

24d=29.6−0.2

24d=29.4

d= 29.4/24

d=294/240

d=49/40

d=1.225

To solve the equation, you just need to isolate the variable d. Here's the equation:

24d + 0.2 = 29.6First, subtract 0.2 from both sides:24d = 29.4Now, divide both sides by 24 to solve for d:d = 29.4 / 24d ≈ 1.225

Answer:

5 ft

Step-by-step explanation:

In order to find the missing side length, we need to take a look at what has been given to us.

From what I see, this shape looks like two rectangles connect at their ends.

What do we know about rectangles?

-Rectangles have 2 sets of sides that are equal length, totaling 4 sides.

So, let's say we know the length of the longest side of the tallest rectangle.

-That side length is 15ft.

Now, we know that the opposite side of that imaginary rectangle has to be of equal length of 15ft. But, only 10 ft are show...

Since we know that there are more than 10 ft we must subtract 10 ft from the 15 ft to get the side length marked as "?", or what should have been left at that side.

15ft - 10ft = 5ft

n=3n+162, minus, start fraction, 1, divided by, 2, end fraction, n, equals, 3, n, plus, 16

=
n=n, equals

Answers

To solve this equation, we can first simplify the left-hand side:

2^(3n+1) / (2^n - 1) = 3n + 16

We can then multiply both sides by 2^n - 1 to eliminate the denominator:

2^(3n+1) = (3n + 16)(2^n - 1)

Expanding the right-hand side:

2^(3n+1) = 6n*2^n + 16*2^n - 3n - 16

Simplifying:

2^(3n+1) = (6n - 3n)*2^n + (16 - 16)

2^(3n+1) = 3n*2^n

Dividing both sides by 2^n:

2^(n+1) = 3n

Taking the logarithm of both sides (with any base), we get:

n log(2) + log(2) = log(3n)

n = (log(3n) - log(2)) / log(2)

We can use a calculator to evaluate this expression, or simplify it further using logarithm rules:

n = log2(3n/2)

We can now use iterative methods or a graphing calculator to find a numerical solution for n. The solution is approximately 7.524.

The solution would be 7.524 I’m pretty sure

Ex: 1,2,3,4,5 is the number list so you add 1,2,3,4, and 5. Then you divide that sum by 5 because there is 5 numbers there.

Median is simply just the middle of the list, for ex 1,2,3,4,5 3 is the median, but if it is 1,2,3,4,5,6 then you would make it 3.5.

Mode is the most repeated number in the list

Ex: 1,1,2,3,4,5,5,5,6,7

The Mode in the list is 5, since it is repeated 5 times. If none repeated then it is N/A if it is tied then put both numbers.

Answers

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.
