Answer: [tex]x_1=2\\\\x_2=-\frac{1}{2}[/tex]

Step-by-step explanation:

To find the zeros of the quadratic equation given in the exercise, you need to apply the proccedure shown below:

- You must rewrite it as following:

[tex]6x^2-9x-6=0[/tex]

-You can apply the Quadratic formula, which is shown below:

[tex]x=\frac{-b\±\sqrt{b^2-4c}}{2a}[/tex]

In this case:

[tex]a=6\\b=-9\\c=-6[/tex]

- Therefore, when you substitute values, you obtain:

[tex]x=\frac{-(-9)\±\sqrt{(-9)^2-4(6)(-6)}}{2(6)}[/tex]

[tex]x_1=2\\\\x_2=-\frac{1}{2}[/tex]

Answer:

Perpindicular ---

construction - the walls need to be build at a perfect shape

interior decorating - things need to be hung on the wall, properly aligned

carpentry - if you want to build a square you need to make a line perpendicular to the first piece of wood, to make a perfect right angle

Step-by-step explanation:

Architects and engineers use parallel and perpendicular lines in technical drawings to ensure accuracy and consistent dimensions, while artists may use these concepts in perspective artwork. Physics calculations involving moments of inertia also apply these principles in determining rotational properties of objects.

Many professions use the concepts of parallel and perpendicular lines. For instance, architects and engineers frequently use parallel and perpendicular lines in their drawings and designs. When architects design buildings with a rectangular plan, they rely on parallel projections, where they scale down a two-dimensional representation of the building while maintaining parallel lines. Engineering drawings, such as those for machine parts, also employ parallel and perpendicular lines to convey the dimensions and orientation of objects accurately.

Artists working in perspective, on the other hand, often employ the concept that parallel lines appear to converge at a vanishing point in the distance, as seen in linear perspective artwork. However, for technical drawings where accuracy and measurement are key, the parallel projection method is crucial as it allows for dimensions to remain consistent.

In physics, moments of inertia calculations for objects like discs and rods often utilize parallel and perpendicular axes theorems to determine rotational properties. And in geometry, constructions frequently involve drawing parallel or perpendicular lines from given points, which is fundamental in defining figures and solving problems.

Answer:

Time, t = 1.875 seconds

Step-by-step explanation:

It is given that,

Initial velocity of the ball, u = 30 ft/s

DeSean throws a ball from a platform that is at ground level. The equation of motion when an object is thrown vertically upward is given by the following equation as :

[tex]h(t)=-16t^2+vt+h[/tex]

Here, h = 0 since, the ball is thrown up at the ground level. We have to determine the time when the ball be in air. The quadratic equation becomes :

[tex]-16t^2+30t+0=0[/tex]

t = 1.875 seconds  

So, the ball be in air for 1.875 seconds. Hence, this is the required solution.

Answer:

Option B. [tex]p=k/b[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

Let

p-----> the number of painters

b----> the time taken to paint the building

we know that

[tex]p*b=k[/tex]

so

[tex]p=k/b[/tex]

Answer:

B. [tex]p=\frac{k}{b}[/tex]

Step-by-step explanation:

Given,

The number of painters, p, employed to paint a building is inversely proportional to the time taken to paint the building, b

[tex]\implies p\propto \frac{1}{b}[/tex]

[tex]\implies p=\frac{k}{b}[/tex]

Where, k is the constant of proportionality,

Hence, the required equation that models the relation between p and b is,

[tex]p=\frac{k}{b}[/tex]

Option 'B' is correct.

$3 dollar coupons were given

Step-by-step explanation:

We can represent this question as a system of equations

Let

x = number of $1 dollar coupons

y = number of $3 dollar coupons

z = number of $5 dollar coupons

Twice as many $1 coupons were given out as $3 coupons,

x = 2*y

3 times as many $3 coupons were given as $5 coupons.

y = 3*z

The total value of all the coupons given out was $360

x*$1 + y*$3 + z*$5 = $ 360

The system results

x   -   2y   +  0    =  0         (1)

0   +  y     -  3z    = 0         (2)

x    + 3*y      +5*z =   $ 360    (3)

We substitute  equation (2) and (1) into (3)

(2y)   + 3*y    + 5*(y/3) =   $ 360

20*y/3  = 360

y = 54

To determine the number of $3 coupons given out by the bakery, we solved the equation 5x + 3(3x) + 1(2(3x)) = $360, where x represents the number of $5 coupons. We found that x = 18, and since there are three times as many $3 coupons as $5 coupons, the bakery gave out 54 $3 coupons.

The question involves solving a system of linear equations to determine how many $3 coupons were given out by the bakery. Let's define the variables first:

Based on the given information, we can set up the following equations:

Now let's solve the equation:

Once we have x, we know that the number of $3 coupons is 3 times x, so:

3x = 3(18) = 54

Therefore, 54 $3 coupons were given out by the bakery.

Answer:

[tex]y=-\frac{3}{5} x+6[/tex]

Step-by-step explanation:

Lets solve the equation [tex]3x+5y=30[/tex] for [tex]y[/tex] step-by-step:

Step 1. Subtract [tex]3x[/tex] from both sides of the equation

[tex]3x+5y=30[/tex]

[tex]3x-3x+5y=-3x+30[/tex]

[tex]5y=-3x+30[/tex]

Step 2. Divide both sides of the equation by 5

[tex]\frac{5y}{5} =\frac{-3x+30}{5}[/tex]

[tex]y=\frac{-3x+30}{5}[/tex]

[tex]y=-\frac{3}{5}x+\frac{30}{5}[/tex]

[tex]y=-\frac{3}{5} x+6[/tex]

We can conclude that the equation that can be used for solve for [tex]y[/tex] is [tex]y=-\frac{3}{5} x+6[/tex]

Answer:

y = -3x/5 + 6

Step-by-step explanation:

Given the equation 3x+5y = 30, to find the equation that can be used to solve for y, we will have to make y the subject of the formula from the given linear equation to have;

3x + 5y = 30

First we will subtract 3x from both sides of the equation to have;

3x+5y-3x = 30-3x

5y = 30-3x

Dividing both sides of the equation by the coefficient of y which is 5 we will have;

5y/5 = 30/5-3x/5

y = 6-(3x/5)

y = -3x/5 + 6

Answer:

[tex]y + 1 = -\frac{2}{5}(x+5)[/tex]

and

2x + 15y = -15

Step-by-step explanation:

To write the point slope form, a point and a slope is required. Find the slope using the two points given and the slope formula.

[tex]m = \frac{y_2-y_1}{x_2-x_1}= \frac{-1 --7}{-5-10}= \frac{6}{-15} = -\frac{2}{5}[/tex]

Substitute -2/5 and the point (-5,-1) into the form. Then convert to make the standard form of the equation.

[tex]y - y_1 = m(x-x_1)\\y --1=-\frac{2}{5}(x--5)\\y + 1 = -\frac{2}{5}(x+5)[/tex]

Now convert to standard form by applying the distributive property and moving terms.

[tex]y + 1 = -\frac{2}{5}(x+5)\\y + 1 = -\frac{2}{5}x - 2\\y + 3 = -\frac{2}{5}x\\\frac{2}{5}x + y +3=0\\2x + 5y + 15 = 0\\2x + 15y = -15[/tex]

Answer:

Step-by-step explanation:

Use the distributive property a(b + c) = ab + ac:

8( -10x + 3.5y - 7)

= (8)(-10x) + (8)(3.5y) + (8)(-7)

= -80x + 28y - 42

8(-10x + 3.5y - 7)

= (4)(2)(-10x + 3.5y - 7)

= 4[(2)(-10x) + (2)(3.5y) + (2)(-7)]

= 4(-20x + 7y - 14)

The expression 8(-10x+3.5y-7) equivalent to -80x + 28y - 56.

Let the expression be

8(-10x + 3.5y - 7)

Simplifying the above equation as

[tex]$\ 8\left(-10 x+\frac{35}{10} y-7\right)$[/tex]

Multiplying the equation, then we get

[tex]$-80 x+8 \times \frac{35}{10} y-8 \times 7$[/tex]

[tex]$-80 x+4 \times \frac{35}{5} y-56$[/tex]

[tex]$-80 x+4 \times 7 y-56$[/tex]

- 80x + 28y - 56

Therefore, the correct answer is option (b) - 80x + 28y - 56.

The conic section is Parabola. It intersects at point (0,5) on the y-axis. The domain of the parabola is all real numbers. The range of the parabola is [tex]y\ |y \ge 5[/tex].

The image appears to be a graph of a parabola. Here's the information:

Type of conic section: Parabola

Center: This parabola doesn't have a center, as parabolas are not symmetrical across both axes.

Intercepts: The parabola intersects the y-axis at the point [tex]$(0, 5)$[/tex]. It doesn't intersect the x-axis.

Domain: The domain of the parabola is all real numbers, as it extends infinitely in both directions to the left and right.

Range: The range of the parabola is all real numbers greater than or equal to 5, as it starts at the point [tex]$(0, 5)$[/tex] and extends infinitely upwards.

The center and intercepts of a conic section vary depending on the specific type. The domain and range also differ based on the nature of the conic section, with some having a limited set of x or y values, while others span all real numbers with exceptions.

To identify the center and intercepts of a conic section, we first need the specific equation of the conic section (circle, ellipse, parabola, or hyperbola). The intercepts are the points where the graph intersects the x-axis and y-axis. The center of a conic section (for circles and ellipses) is the point inside the conic section that is equidistant from all points on the curve. For parabolas, the center does not exist since they are open-ended curves, and for hyperbolas, the center is the midpoint between the vertices of the two branches of the curve.

The domain and range are the set of possible x-values and y-values respectively that the function (conic section) can take. For circles and ellipses, the domain and range are limited to the values within the bounds of those shapes. Parabolas have an infinite domain when the axis of symmetry is vertical and an infinite range when the axis of symmetry is horizontal, except if there is a horizontal directrix, which restricts the range. Hyperbolas have a domain and range all real numbers except for values that fall within the 'gap' created by the asymptotes.

Final answer:

The residual for the data point (4,13) given the line of best fit y=5x-2.5 is -4.5, indicating the line overestimates the value of y by 4.5 units.

Explanation:

The student is asking about finding the residual for a data point (4,13) given the line of best fit with the equation y=5x-2.5. To find the residual, you calculate the difference between the actual y value of the data point and the predicted y value from the line of best fit. For the given point, the predicted y value is calculated by substituting x=4 into the line equation, yielding y = 5(4) - 2.5 = 17.5. The residual is the actual y value minus the predicted y value: 13 - 17.5 = -4.5. Therefore, the residual for the point (4,13) is -4.5, indicating that the line of best fit overestimates the actual data value for y by 4.5 units.

The numbers in decreasing order of their values are:

[tex]\cfrac{19}{3}>\sqrt{37}>6.08171...>6.012[/tex]

Step-by-step explanation:

Before actually comparing, we need to write all of those numbers in decimal form, that will be the only way to actually tell which one is bigger since you are already given numbers in decimal form.

Converting numbers in decimal form.

The first number we are given is [tex]\sqrt{37}[/tex], we know it is a bit higher than 6, since the square root of 36 is 6, so using a calculator we get

[tex]\sqrt{37}=6.0828[/tex]

The second number is a fraction, in decimal form will be:

[tex]\cfrac{19}{3}= 6.3333[/tex]

Writing the decreasing order.

Now that all numbers are in decimal form we can compare them and write them in decreasing order.

[tex]6.3333... > 6.0828...>6.08171...>6.012[/tex]

Lastly we can write the decreasing order using the numbers on their original form.

[tex]\cfrac{19}{3}>\sqrt{37}>6.08171...>6.012[/tex]
