Steps to finding the x-intercept and y-intercept of y=16x^2+32x

Answers

Answer 1

Answer:

y-intercept = (0,0)

x-intercepts (0,0), (-2, 0)

Step-by-step explanation:

For y-intercept

If you think about a graph, when does the graph intercept/hit y.   What is your value for x.   Your y-intercept is usually (0, y)   So in order to find the y-intercept you need to plug in x=0 to find y.

Equation:

y=16x²+32x       substitute x=0

y=16(0)²+32(0)

y=0

y-intercept = (0,0)

For x-intercept

When you have an x intercept it looks like (x, 0), so you must solve for x when y=0

Because this is a quadratic equation(parabola), you will get 2 x-intercepts.

y=16x²+32x

0=16x²+32x      > In order to solver for x, you must factor but in this case

                            you can take out the greatest common factor (GCF) =16x

0=16x(x +2)       >Typically when you factor you get 2 parentheses and set

                            each parenthesis equal to 0, but instead we've pulled

                            an x on the outside.  When there is an x outside you set

                            the outside equal to 0 as well as the parenthesis to

                            solve for x.

16x = 0                 (x+2)=0

x=0                           x= -2

x-intercepts (0,0), (-2, 0)

Find the area of the triangle with vertices A(-3, 2), B(1, - 2). and C(1, 3).​

Answers

Answer:

10 units squared

Step-by-step explanation:

Main steps

Step 1. Identify which leg to use as a base

Step 2. Calculate the base length

Step 3. Calculate the height

Step 4. Calculate the area

Step 1. Identify which leg to use as a base

We are given that the shape is a triangle.  The formula for the area of a triangle is [tex]A_{triangle}=\frac{1}{2}bh[/tex] where b is the "base" of a triangle, and h is the "height".

One common misconception is that the base must be at the bottom (although it is easy to think of it that way).  Rotating the shape, any of the three sides could be at the bottom, and thus any of the three sides could be the base.

The "height" of the triangle depends on which leg is being used as a base.  The height for a given base is always the shortest distance from the vertex opposite the base to the line that contains the base.  This shortest distance always ends up being the line segment that is perpendicular to the base.

In this case, since side BC is along the gridlines, it will be easiest to use side BC as the base, because the perpendicular line for the height will be along gridlines.  The height is the distance from A to the side BC (which is a line segment between (-3,2) and (1,2)).

Step 2. Calculate the base length

The base length is the distance between the two endpoints of the line segment.  The distance formula is [tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using Point B as Point 1, and Point C as Point 2:

[tex]D=\sqrt{((1)-(1))^2+((3)-(-2))^2}[/tex]

[tex]D=\sqrt{(0)^2+(5)^2}[/tex]

[tex]D=\sqrt{0+25}[/tex]

[tex]D=\sqrt{25}[/tex]

[tex]D=5[/tex] units

So the base length is 5 units

b=5 units

Since these point are on a graph, it can be verified by counting the squares between the two points, however if work needs to be shown, the Distance formula is the "work".

Step 3. Calculate the height

The "height" for the base from step 2 is a line segment between (-3,2) and (1,2).  This distance can again be found using the distance formula:

Using Point A as Point 1, and the point (1,2) on BC as Point 2:

[tex]D=\sqrt{((-3)-(1))^2+((2)-(2))^2}[/tex]

[tex]D=\sqrt{(-4)^2+(0)^2}[/tex]

[tex]D=\sqrt{16+0}[/tex]

[tex]D=\sqrt{16}[/tex]

[tex]D=4[/tex] units

So the height for the base from Step 2 is 4 units.

h=4 units

Again, these point are on a graph, so this answer can be verified by counting the squares between the two points.

Step 4. Calculate the area

Using the formula for the area of a triangle discussed in Step 1, the area can be calculated:

[tex]A_{triangle}=\frac{1}{2}(5~\text{units})(4~\text{units})[/tex]

[tex]A_{triangle}=10 \text{ units}^2[/tex]

which of the following are true statements? i. based on careful use of control groups, experiments can often indicate cause-and-effect relationships. ii. while observational studies may suggest relationships, great care must be taken in concluding that there is cause and effect because of the lack of control over lurking variables. iii. a complete census is the only way to establish a cause-and-effect relationship absolutely

Answers

Based on control groups, experiments indicate cause-and-effect relationships. While observational studies, great care must be taken in concluding cause and effect. Correct options are i and ii.

Statement i is a true statement. Experiments are designed to test causal relationships between variables by manipulating one variable while keeping all others constant, allowing researchers to establish cause-and-effect relationships with greater certainty.

The use of control groups allows researchers to isolate the effects of the independent variable from other potential confounding variables.

Statement ii is also a true statement. Observational studies are more prone to the influence of lurking variables that cannot be controlled for, which makes it more difficult to establish a cause-and-effect relationship between variables.

However, careful analysis and the use of statistical methods can help control for the influence of some lurking variables and provide evidence to support a causal relationship.

Statement iii is a false statement. While a complete census can provide comprehensive information about a population, it does not necessarily establish cause-and-effect relationships absolutely.

Causality is typically established through well-designed experiments or observational studies that carefully control for confounding variables, and it is rare for any single study to establish causal relationships with absolute certainty.

Instead, scientific evidence is accumulated over time through multiple studies that support the same conclusion, and even then, there is always some degree of uncertainty and potential for alternative explanations.

Correct options are i and ii.

To identify transformations, we have to be conversant with various rules of transformation. When we reflect over the x or y-axis, the signs of the coordinates for x or y are supposed to change to negative.

However, Any transformation that happens such that the coordinates of the equation are both positive means that the image is on the first quatrain of the graph, which is the right and upper side of the x-axis.

If the rectangle is at the second quatrain, and it is rotated 180° degrees, it means that it still maintains its upright position. and when it is reflected back through the x-axis, it still maintains its upright position.

If the rectangle is rotated 90° counterclockwise, it bends and therefore the coordinates change.

of water. They plan to add a ride that would make use of an additional 7.8 x 10³
gallons of water. Use scientific notation to express the total gallons of water made use
of in the park after the new ride is installed.

Answers

Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

The form of the container the water is contained in affects how much water is contained inside. You must know the length, breadth, and depth of a square or rectangular vessel in order to calculate its volume using the volume equation V=L*W*D, where L stands for length, W for width, and D for depth. The volume equation in this case reads: V= (r²)Dπ, where r stands for the radius, D for depth, and, or pi, is a constant value that is typically rounded to 3.14. To perform the same volume calculation for a circular vessel, you must know the vessel's depth and diameter or radius.

Given, the water park has water which is 8.6*10⁵ gallons.

We know that 10⁵ = 100000

Thus, 8.6*10⁵ = 860000

The new ride would use an additional 9.1*10⁴ gallons.

Again, 10⁴ = 10000

Thus, 9.1*10⁴ = 91000

Total water that would be required now is equal to the sum of the original water volume and the volume required by the new ride

= (860000+91000) gallons

= 951000 gallons

= 9.51*10⁵ gallons

Hence, the total gallons of water made use of in the park after the new ride is installed is 9.51*10⁵ gallons

2. a. The total cost of 60 apples and 100 eggs is €108,000.00. The cost of 72 apples is the same as that of 30 eggs. Find how much 12 apples and 20 eggs will cost.​

Answers

Answer:

12 apples and 20 eggs will cost €38,880.

Step-by-step Explanation:

Let's use algebra to solve the problem.

Let x be the cost of one apple and y be the cost of one egg in euros.

From the first statement, we can write two equations:

60x + 100y = 108,000 (equation 1)

From the second statement, we can write another equation:

72x = 30y (equation 2)

We want to find the cost of 12 apples and 20 eggs, which can be written as:

12x + 20y

Now we can use the second equation to solve for one variable in terms of the other.

Rearranging equation 2, we get:

y = (72/30)x

Substituting this into equation 1, we get:

60x + 100(72/30)x = 108,000

Simplifying:

60x + 240x = 108,000

300x = 108,000

x = 360

Now we can use this value of x to find y:

72x = 30y

72(360) = 30y

y = 1,728

Therefore, the cost of 12 apples and 20 eggs is:

12x + 20y
= (12)(360) + (20)(1,728)
= 4,320 + 34,560
= 38,880 euros.

So 12 apples and 20 eggs will cost €38,880.

In art class students are mixing blue and red paint to make purple paint. Madelyn mixes 3 cups of blue paint and 10 cups of red paint. Arturo mixes 1 cup of blue paint and 4 cups of red paint. Whose purple paint will be redder?

Answers

Answer:

To compare the purple paints that Madelyn and Arturo made, you need to find the ratio of red to blue in each mixture. You can do this by dividing the amount of red paint by the amount of blue paint.

For Madelyn, the ratio of red to blue is:

10 / 3 = 3.33

For Arturo, the ratio of red to blue is:

4 / 1 = 4

Since Arturo has a higher ratio of red to blue, his purple paint will be redder than Madelyn’s.

The function rule for g(x) is f(x) = (x - 5)² + 0.

How to determine the function rule?

In Mathematics and Geometry, the translation of a graph to the right simply means adding a digit to the value on the x-coordinate of the pre-image.

In Mathematics and Geometry, a horizontal translation to the right is modeled by this mathematical equation g(x) = f(x + N) while a vertical translation to the positive y-direction (downward) is modeled by this mathematical equation g(x) = f(x) - N.

Where:

N represents an integer.g(x) and f(x) represent functions.

Since the parent function is represented by f(x) = x², a function rule for g(x) is given by;

f(x) = a(x − h)² + k

f(x) = 1(x - 5)² + 0.

While grocery shopping, Dylan bought
some apples for $3.50. He also bought
some grapes that cost $1.25 more than
the apples. The combined cost of the
grapes and apples made up 20% of his
total grocery bill. What was the total
amount of Dylan's grocery bill in dollars
and cents?

Answers

Answer:

Dylan's grocery bill was $41.25.

Step-by-step explanation:

Let's call the cost of the grapes "g".

We know that the grapes cost $1.25 more than the apples, so we can write:

g = 3.50 + 1.25 = 4.75

The combined cost of the grapes and apples is 20% of Dylan's total grocery bill, so we can write:

3.50 + 4.75 = 0.20x

where x is the total grocery bill.

We can solve for x by simplifying the equation:

8.25 = 0.20x

x = 8.25 / 0.20

x = 41.25

Therefore, the total amount of Dylan's grocery bill was $41.25.

Answer:  

Dylan's total grocery bill was $41.25

Step-by-step explanation:

Let the cost of the apples be a. Then, the cost of the grapes is a + 1.25, since the grapes cost $1.25 more than the apples.

The combined cost of the apples and grapes is a + (a + 1.25) = 2a + 1.25.

We know that the combined cost of the apples and grapes is 20% of Dylan's total grocery bill, so we can set up the following equation:

2a + 1.25 = 0.2x

where x is the total cost of Dylan's grocery bill.

To solve for x, we can isolate x on one side of the equation:

2a + 1.25 = 0.2x

2a = 0.2x - 1.25

a = 0.1x - 0.625

We also know that the cost of the apples is $3.50, so we can set up another equation:

a = 3.5

Substituting this into the equation we just found:

3.5 = 0.1x - 0.625

4.125 = 0.1x

x = 41.25

Therefore, Dylan's total grocery bill was $41.25.

suppose i have an organization that has 60 members, i'm going to pick one person at random to be the president, another person to be the vice president, and a third person to be the treasurer. how many ways can this be done?

Answers

There are 205,320 ways to select one person to be the president, one person to be the vice president, and a third person to be the treasurer from a group of 60 members.

The number of ways to select the president from the 60 members is 60, since any one of the 60 members can be chosen.

Once the president has been chosen, there are only 59 members left to choose from for the vice president. Therefore, there are 59 ways to select the vice president.

Similarly, after the president and vice president have been chosen, there are only 58 members left to choose from for the treasurer. Therefore, there are 58 ways to select the treasurer.

Using the multiplication principle of counting, the total number of ways to select one person to be the president, one person to be the vice president, and a third person to be the treasurer is

the team wins .73 of their games. if they play 10 games, what is the probability that they win nine games?

Answers

Thus, the probability that the team wins nine games out of 10 is approximately 0.2365, or about 23.65%.

To solve this problem, we can use the binomial distribution formula:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

Where:
- P(X = k) is the probability of getting exactly k successes
- n is the total number of trials (games played)
- k is the number of successes (games won)
- p is the probability of success in one trial (winning a game)
- (n choose k) is the binomial coefficient, which can be calculated as n! / (k! * (n - k)!)

In this case, n = 10, p = 0.73, and k = 9. So we have:

P(X = 9) = (10 choose 9) * 0.73^9 * (1 - 0.73)^(10 - 9)
P(X = 9) = 10 * 0.73^9 * 0.27^1
P(X = 9) = 0.2365

Therefore, the probability that the team wins nine games out of 10 is approximately 0.2365, or about 23.65%.

I'm a number between 17 and 25 i'm a multpile of 3 6 is not mynfactor

Answers

The number that fits the given criteria is 21.

The number 21 is between 17 and 25, and it is a multiple of 3. It is not a multiple of 6 because it is not divisible evenly by 6.

The factors of 21 are 1, 3, 7, and 21. Since 6 is not one of its factors, 21 satisfies the given conditions.

To find the answer, we first identify the range of numbers given, which is between 17 and 25.

Next, we look for a number within this range that is a multiple of 3. Multiples of 3 are numbers that can be divided evenly by 3 without leaving a remainder.

Among the numbers in the given range, only 21 satisfies this condition. Lastly, we check if the number is a multiple of 6. A multiple of 6 is a number that can be divided evenly by 6 without leaving a remainder.

Since 21 cannot be divided evenly by 6, it does not meet this criterion. Therefore, 21 is the number that fits all the given conditions.

the life of light bulbs is distributed normally. the standard deviation of the lifetime is 15 hours and the mean lifetime of a bulb is 530 hours. find the probability of a bulb lasting for between 557 and 561 hours. round your answer to four decimal places.

Answers

The probability of a bulb lasting for between 557 and 561 hours is roughly 0.0382 or 3.82%

Able to utilize the standard ordinary dissemination to discover the likelihood of a bulb enduring for between 557 and 561 hours. To do this, we ought to standardize the values utilizing the equation:

z = (x - μ) / σ

where x is the bulb lifetime we're fascinated by

, μ is the cruel(mean) lifetime,

and σ is the standard deviation.

For 557 hours:

z1 = (557 - 530) / 15 = 1.8

For 561 hours:

z2 = (561 - 530) / 15 = 2.07

Employing a standard ordinary conveyance table or a calculator with a typical dissemination work, we are able to discover the probabilities corresponding to these z-scores:

P(z1 < Z < z2) = P(1.8 < Z < 2.07)

This speaks to the likelihood of a bulb enduring between 557 and 561 hours, where Z could be a standard ordinary variable.

Employing a standard ordinary dispersion table or a calculator, we discover:

P(1.8 < Z < 2.07) ≈ 0.0382

Therefore, the likelihood of a bulb enduring for between 557 and 561 hours is roughly 0.0382 or 3.82% (adjusted to four decimal places).

The values of x make the triangle a right triangle is 25

What values of x make the triangle a right triangle?

Given that

Legs = 15 and 20

For a right triangle, we have

x^2 = 15^2 + 20^2

So, we have

x^2 = 625

This gives

x = 25

What values of x make the triangle an acute triangle?

In this case, the value of x would be less than 25 calculated above

Lemons (25 points) A buyer wishes to purchase a good from a seller. The good is worth 0 to the buyer and 0.80 to the seller. The buyer makes a take-it-or-leave-it offer of price p to the buyer, and the seller either accepts or rejects. Rejection means the buyer gets nothing but pays nothing (), and the seller keeps the good (0.80). Acceptance means the buyer pays p but gets the good (0 p) and the seller loses the good but gets the money (p). a. First, suppose this is a dynamic game of complete information, i.e., is common knowledge. Find the unique SPNE outcome-i.e., what p is offered, is it accepted or rejected. Hint: Use backward induction. Going forward, it is common knowledge that 6 is distributed as follows: of the time 0 = 1, of the time 0 = 2, and of the time 8 = 3. Thus, the (unconditional) "average" is 2. Importantly, the seller knows the true value of e. b. What is the seller's decision rule (accept when [circumstance], reject otherwise) for some p?
