Step-by-step explanation:

maxines function is negative while ricardo's is positive

ranges:

ricardo:y>or equal to 4

maxine:y<or equal to 4

the points we plotted are (-6, -1/2), (-4, 1/2), (0, -1/5), (3, 1/2), and (6, 1/5).

What is function?

a function is a relationship or expression involving one or more variables.  It has a set of input and outputs.

To find the x-intercepts, we set the numerator of the function equal to zero:

[tex]2 / (x^2 + 3x - 10) = 0[/tex]

This is only true if the numerator is equal to zero, so:

2 = 0

This is not possible, so the function has no x-intercepts.

To find the vertical asymptotes, we look for values of x that make the denominator equal to zero:

[tex]x^2 + 3x - 10 = 0[/tex]

We can factor the quadratic as:

(x + 5)(x - 2) = 0

This means that the function has vertical asymptotes at x = -5 and x = 2.

Now, let's plot some points between and beyond each x-intercept and vertical asymptote:

When x = -6, f(x) = 2 / (-6)² + 3(-6) - 10 = -1/2

When x = -4, f(x) = 2 / (-4)² + 3(-4) - 10 = 1/2

When x = 0, f(x) = 2 / (0)² + 3(0) - 10 = -1/5

When x = 3, f(x) = 2 / (3)² + 3(3) - 10 = 1/2

When x = 4, f(x) = 2 / (4)² + 3(4) - 10 = -1/2

When x = 6, f(x) = 2 / (6)² + 3(6) - 10 = 1/5

Therefore, the points we plotted are (-6, -1/2), (-4, 1/2), (0, -1/5), (3, 1/2), and (6, 1/5).

A system of equations that model the situation are e = a - 12 and a + e = 100.

The number of tickets Alberto won is 56 tickets.

The number of tickets Elian won is 44 tickets.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of tickets Alberto won and number of tickets Elian won, and then translate the word problem into an algebraic equation as follows:

Since Alberto won 12 tickets less than Elian, a linear equation that models this situation is given by:

e = a - 12     .....equation 1.

Additionally, when they put their tickets together they have exactly 100 tickets;

a + e = 100     .....equation 2.

By solving the system of linear equations simultaneously, we have:

a + a - 12 = 100

2a = 112

a = 112/2

a = 56 tickets.

For the number of tickets (e) Elian won, we have:

e = a - 12

e = 56 - 12

e = 44 tickets.

Rounding the result off to the nearest 10th, the lateral surface area of the cylinder is 822 inches².

Surface area is the total area of the exposed surfaces of a three-dimensional object. It is measured in square units such as square centimeters (cm2) or square meters (m2). Surface area is an important concept in mathematics, science, and engineering, as it is the total area that determines properties such as friction, heat transfer, and fluid dynamics. For example, a larger surface area can increase the rate of heat transfer and allow for more efficient cooling. Similarly, a larger surface area can increase the friction between two objects, allowing them to grip better. Surface area is also important in chemistry, as it affects the amount of gas or liquid that can be absorbed or released by a given object.

The cylinder has a radius of 11 inches and a height of 12.5 inches. To find the lateral surface area of a cylinder, the formula used is A = 2πrℎ, where r is the radius and h is the height of the cylinder.

7. 9.85 ,   8. 13.04 ,  9. 19.85 ,  10.    7.81

The Pythagorean theorem, commonly referred to as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. It declares that the hypotenuse's square, which is the side that is opposite the right angle, is equal to the sum of the squares of the other two sides. In other words, if the hypotenuse is length c and the legs of a right triangle are lengths a and b, then a² + b² = c².

The Pythagorean theorem, which asserts that the square of the hypotenuse is equal to the sum of the squares of the other two sides, can be used to determine the hypotenuse of a right triangle.

This theorem allows us to calculate the hypotenuse value for each of the right triangles presented as follows:

1. a = 5, b = 8

  c = √(a² + b²) = √(5² + 8²) = √(25 + 64) =√(89) ≈ 9.43

2. a = 6, b = 7

  c = √(a² + b²) = √(6² + 7²) = √(36 + 49) = √(85) ≈ 9.22

3. a = 4, b = 9

  c = √(a² + b²) = √(4² + 9²) = √16 + 81) = √(97) ≈ 9.85

4. a = 3, b = 12

  c =√(a² + b²) = √(3² + 12²) = √(9 + 144) = √(153) ≈ 12.37

5. a = 11, b = 10

  c = sqrt(a^2 + b^2) = sqrt(11^2 + 10^2) = sqrt(121 + 100) = sqrt(221) ≈ 14.87

6. a = 8, b = 7

  c = √(a² + b²)= √(8² + 7²) = √(64 + 49) = √(113) ≈ 10.63

7. a = 9, b = 4

  c =√(a² + b²)=√(9² + 4²) = √(81 + 16) = √(97) ≈ 9.85

8. a = 7, b = 11

  c = √(a² + b²)= √(7² + 11²) = √(49 + 121) ≈√(170) ≈ 13.04

9. a=13,b=15

  c=√(a² + b²)=√((13²)+(15²))=√((169)+(225))=√(394))≈19.85

the proportion of men and women under 30 that use online dating sites.

The null hypothesis, H0, is that there is no difference in the proportion of men and women under 30 that use online dating sites.

The alternative hypothesis, Ha, is that there is a difference in the proportion of men and women under 30 that use online dating sites.

We can use a two-sample z-test for proportions to test this hypothesis.

First, we calculate the pooled sample proportion:

[tex]\^p = (67 + 62) / (96 + 88) = 0.648[/tex]

Next, we calculate the standard error of the difference between the two sample proportions:

[tex]SE =\sqrt{(\^p(1 - \^p) (1/96 + 1/88))} = 0.079[/tex]

The test statistic is:

[tex]z = (\^p1 - \^p2) / SE = (0.698 - 0.705) / 0.079 = -0.886[/tex]

[tex]\^p1 = 67/96 = 0.698[/tex] is the sample proportion of women who use online dating sites, and [tex]\^p2 = 62/88 = 0.705[/tex] is the sample proportion of men who use online dating sites.

Using a two-tailed test with a significance level of [tex]\alpha = 0.05[/tex], we can find the critical value of [tex]z as \±1.96.[/tex]

Since the absolute value of the test statistic, 0.886, is less than the critical value, 1.96, we fail to reject the null hypothesis.

The p-value for this test can also be calculated. Since this is a two-tailed test, we need to find the area under the standard normal distribution curve that is beyond the absolute value of the test statistic:

[tex]p-value = P(|z| > 0.886) = 2P(z < -0.886) = 2(0.187) = 0.374[/tex]

the p-value is greater than the significance level of α = 0.05, we again fail to reject the null hypothesis.

As a result, the cruise ship has travelled roughly 443.92 miles of distance from its starting point.

This merely indicates that the cruise ship moved 325 miles east since it cruises 325 miles directly east. We can more clearly grasp what is happening if we draw a vertical line where he stops. I created the diagram I believe best illustrates this.

According to the diagram, we now need to determine h because it is the distance between our starting point and destination.

The supplement is 150 degrees because the outside angle is 30 degrees.

As a result, we can now use the cosine rule to find h.

x²  = 325² + 150² - 2(325)(150)cos(180 - 30)

x²  = 105625 + 22500 - 97500 cos(150)

What is Quadratic equation?

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0). For writing a quadratic equation in standard form, the x2 term is written first, followed by the x term, and finally, the constant term is written.

Roots of a Quadratic Equation

The roots of a quadratic equation are the two values of x, which are obtained by solving the quadratic equation. These roots of the quadratic equation are also called the zeros of the equation.

Given:

x² - 36 =0

x² = 36

x= √36

x= ±6

hence, the solution is x= +6, -6.

When six integers are chosen from the set A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, there must be at least one pair of integers that adds up to 11. This can be proven using a proof by contradiction.

To solve this problem, we can use a proof by contradiction. We assume that there are six integers chosen from A such that no two integers add up to 11.

If there is no pair of integers in the six chosen that sum up to 11, then we can consider the pairs of integers (1,10), (2,9), (3,8), (4,7), and (5,6). These are the only possible pairs of integers in A that add up to 11.

However, since there are five pairs and we can choose at most one integer from each pair, we can choose at most five integers in total. This is a contradiction since we were asked to choose six integers from A. Therefore, our assumption that there are no pairs of integers that add up to 11 is false.

Hence, we conclude that there must be at least one pair of integers among the six chosen that adds up to 11.

This is a RIGHT triangle, so you can use the Pythagorean theorem

  c^2 = a^2 + b^2    

      where c = hypotenuse ( long side) and a and b are the other two sides (legs)

So for this triangle :

15^2  =   x^2 + 12^2

15^2 - 12^2 = x^2

225  - 144 = x^2

81 = x^2

x = 9  cm  ( the missing side length)

Answer:

x=25.1

Step-by-step explanation:

by using Pythagorean theorem, [tex]a^{2} +b^{2}=c^{2}[/tex] where c is the hypotenuse

[tex]18.15^{2}[/tex]= 329.4225

[tex]17.39^{2}[/tex]= 302.4121

since those two side lengths are the legs, the sum of the numbers is the length of the hypotenuse squared

therefore, 631.8356 (the sum) = [tex]c^{2}[/tex]

by taking the square root of 631.8356, you will get approx 25.1 for the hypotenuse (aka x)

The foci of the ellipse are at (0, -2√11) and (0, 2√11).

To find the foci of the ellipse with equation x²/144 + y²/100 = 1, we need to use the standard form of the equation of an ellipse:

(x - h)²/a² + (y - k)²/b² = 1

where (h, k) is the center of the ellipse, a is the distance from the center to the vertices in the x-direction, and b is the distance from the center to the vertices in the y-direction.

First, let's rewrite the given equation in standard form by dividing both sides by the constant on the right-hand side:

x²/144 + y²/100 = 1

x²/12² + y²/10² = 1

Comparing this with the standard form, we can see that the center of the ellipse is (0, 0), a = 12, and b = 10.

Thus, the distance from the center to each focus is given by c, where:

c² = a² - b²

c² = 12² - 10²

c² = 144 - 100

c² = 44

c = √44

c = 2√11 units

Thus, the distance from the center to each focus is 2√11.

Since the center is at (0, 0), the foci are located at (0, -2√11 and (0, 2√11).

The cost of 4 liters of petrol is 618.

To find the cost of 4 liters of petrol, we can use a proportion. Which means we will equate the two sides of equation having proportions.

We know that 7/2 liters of petrol cost 2163/8. We can write this as,

(7/2) / (2163/8) = 4 / x

where x is the cost of 4 liters of petrol.

To solve for x, we can cross-multiply,

(7/2) * x = (2163/8) * 4

Simplifying both sides, we get,

x = (2163/8) * 4 * (2/7)

The exponential function of the form y=ab^x that has the given points is y = (25/7)(7/5)^x

We can use the given points to set up a system of equations and solve for the values of a and b in the exponential function y = ab^x.

Using the point (1,5), we get:

5 = ab^1

Using the point (2,7), we get:

7 = ab^2

Now, we can solve for a and b by dividing the second equation by the first:

7/5 = (ab^2)/(ab^1

Simplifying this expression, we get:

7/5 = b

Substituting this value of b back into one of the original equations, we can solve for a:

5 = a(b^1) = a(b) = a(7/5)

Simplifying this expression, we get:

a = 25/7

So, the exponential function that passes through the points (1,5) and (2,7) is:

The key features of the graph of the profit function are the following:

The degree of the polynomial function is 3, which means that the graph is a cubic curve.

The coefficient of the leading term is negative (-4), which means that the graph opens downwards.

The coefficient of the quadratic term is positive (32), which means that the graph is concave up.

The y-intercept of the graph is -64, which means that the company will incur a loss of $64,000 if it does not sell any toys.

It should be noted that to find the maximum profit, we need to evaluate the profit function at x = 5.33:

P(5.33) = -4(5.33)^3 + 32(5.33)^2 - 64 = 23.78

Therefore, the maximum profit that the company can make is $23,780.

In summary, the graph of the profit function reveals that the company will incur a loss if it does not sell any toys, but it can make a profit if it sells at least some toys. The profit function has a cubic shape that opens downwards, indicating that the profit decreases as the number of toys sold increases beyond a certain point. The maximum profit occurs at x = 5.33, where the profit is $23,780.

The function f(x) is f(x) = 9x³ - 7x² - 13x - 11 written in standard form.

What is the polynomial equation?

A polynomial equation is an equation in which the variable is raised to a power, and the coefficients are constants. A polynomial equation can have one or more terms, and the degree of the polynomial is determined by the highest power of the variable in the equation.

When f(x) is divided by 3x + 1, the quotient is 3x² - 4x - 1 and the remainder is -10. We can use polynomial long division to write f(x) in the form:

f(x) = (3x² - 4x - 1)(3x + 1) - 10

Multiplying out the right side gives:

f(x) = 9x³ - 7x² - 13x - 11

Therefore, the function f(x) is f(x) = 9x³ - 7x² - 13x - 11 written in standard form.

Answer:

Step-by-step explanation:

Making x the subject in the second equation gives:

x = 4+3y

substituting x = 4 +3y into the first one gives:

3(4 + 3y) + 2y = -21

12 + 9y +2y = -21

11y = -33

y = -3
