The answer in the procedure

Step-by-step explanation:

we know that

The zeros of the function are the values of x when the value of y is equal to zero

In this problem

The zeros of the function are the price of a hot dog (in dollars) when the daily profit (in hundreds of dollars) of a hot dog stand are zero

we have

[tex]y=-2(x-3)^{2}+4[/tex]

using a graphing tool

The zeros of the function are

x=$1.59, x=$4.41

so

for these prices the daily profit are zero

see the attached figure

Answer:

Step-by-step explanation:

I think I have helped you before with this problem, substitute x and y with -3 and 8 respectively, so 5*(-3)+8b=17, -15+8b=17, 8b=32, divide both sides by 8 and you get b=4

Start with

[tex]\dfrac{x}{2}+\dfrac{3}{2}<\dfrac{5}{2}[/tex]

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

[tex]x+3<5[/tex]

Subtract 3 from both sides:

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.

Answer:

[tex]20.11\ cm[/tex]

Step-by-step explanation:

we know that

The surface area of the cone is equal to

[tex]SA=\pi r^{2}+\pi rl[/tex]

where

r is the radius

l is the slant height

In this problem we have

[tex]SA=822.78\ cm^{2}[/tex]

[tex]r=18/2=9\ cm[/tex] -----> the radius is half the diameter

substitute and solve for l

[tex]822.78=\pi (9)^{2}+\pi (9)l[/tex]

[tex]822.78=81\pi +9\pi l[/tex]

[tex]l=(822.78-81\pi)/9\pi[/tex]

[tex]l=(822.78-81(3.14))/9(3.14)=20.11\ cm[/tex]

The slant height of the cone is approximately 20.1154 cm.

[tex]\[ \text{Surface Area} = \pi r (l + r) \][/tex]

where r is the radius of the base of the cone, and l is the slant height of the cone.

Given that the diameter of the cone is 18 cm, we can find the radius r by dividing the diameter by 2:

[tex]\[ r = \frac{diameter}{2} = \frac{18 \text{ cm}}{2} = 9 \text{ cm} \][/tex]

Now we can substitute the values we know into the surface area formula:

[tex]\[ 822.78 \text{ cm}^2 = \pi \times 9 \text{ cm} \times (l + 9 \text{ cm}) \][/tex]

To find l, we need to solve for l in the equation:

[tex]\[ 822.78 \text{ cm}^2 = 9 \pi \text{ cm} \times (l + 9 \text{ cm}) \] \[ \frac{822.78 \text{ cm}^2}{9 \pi \text{ cm}} = l + 9 \text{ cm} \] \[ \frac{822.78}{9 \pi} = l + 9 \] \[ l = \frac{822.78}{9 \pi} - 9 \][/tex]

Now we calculate the value of l:

[tex]\[ l = \frac{822.78}{9 \times \pi} - 9 \] \[ l = \frac{822.78}{28.27433388} - 9 \] \[ l \approx 29.1154 - 9 \] \[ l \approx 20.1154 \text{ cm} \][/tex]

Answer: [tex](x+3)^2+(y+5)^2=25[/tex]

Step-by-step explanation:

The equation of the in center-radius form  is the shown below:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where the center is at the point (h,k) and r is the radius of the circle.

Based on the information given in the problem, the center of the circle is at the point (-3,-5) and a radius of the circle is 5, then,  you must substitute values into the equation shown above.

Therefore, you obtain the following equation:

[tex](x-(-3))^2+(y-(-5))^2=(5)^2[/tex]

[tex](x+3)^2+(y+5)^2=25[/tex]

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.

The riddle 'what asks no questions but must be answered' typically refers to a telephone or a doorbell, both of which signal when someone is attempting to communicate or get attention.

The student's question, "what asks no questions but must be answered," is a type of riddle, which is a question or statement intentionally phrased to require ingenuity in ascertaining its answer. In this context, the answer to the riddle is typically the telephone or a doorbell, as both signal when someone is trying to get in contact or gain attention, and generally, one responds to them. Riddles can form part of the teaching in English, particularly when focusing on language play, word definitions, and understanding semantics. They can encourage students to pay attention to wording and to contemplate why certain expressions carry the meanings they do.

The solution to the inequality [tex]\( p \geq -1 \)[/tex] represents all the values of  p that are greater than or equal to -1.

To represent this on a graph, you would draw a number line with an open circle at -1 (since it's "greater than or equal to", not just "greater than"), and then shade to the right to indicate all values greater than -1.

The open circle at -1 indicates that -1 is not included in the solution, and the shaded area to the right indicates all values greater than -1.

Answer:

130 ft^2

Step-by-step explanation:

SA= surface area

SA= 2*l*w + 2*l*h + 2*w*h

l= length = 10

w= width =5

h = height = 1

SA= 2*l*w + 2*l*h + 2*w*h

SA= 2*10*5 +2*10*1+2*5*1

SA= 100+20+10

SA= 130 ft^2

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.

8,000,000 minus 200 = answer

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.
