sarah has sold $33 worth of tickets sales to the comedy show. She has 4 tickets left to sell at $11 per hour

Answers

The equation would be y=11x+33.

The x can be 0, 1, 2, 3, 4. It cannot be any other number than these 5.
Y is just whatever you get when you plug the x in for 0, 1, 2, 3, or 4

Answer:

The domain of the function is {0,1,2,3,4} and the range of the function is {$33, $44, $55, $66, $77}

Step-by-step explanation:

Consider the provided information.

Sarah has sold $33 worth of tickets sales to the comedy show. She has 4 tickets left to sell at $11 per hour.

First write the function as shown.

Let the number of tickets are x and she already sold $33 worth of tickets.

Therefore the function is: [tex]f(x)=11t+33[/tex]

For t=0

[tex]f(0)=11(0)+33=33[/tex]

For t=1

[tex]f(1)=11(1)+33=44[/tex]

For t=2

[tex]f(2)=11(2)+33=55[/tex]

For t=3

[tex]f(3)=11(3)+33=66[/tex]

For t=4

[tex]f(4)=11(4)+33=77[/tex]

Hence, the domain of the function is {0,1,2,3,4} and the range of the function is {$33, $44, $55, $66, $77}

Max makes and sells posters. The function p(x)= -10x^2 +200x -250, graphed below, indicates how much profit he makes in a month if he sells the posters for 20-x dollars each. (Picture in comments) What should Max charge per poster to make the maximum profit, and what is the maximum profit he can make in a month? A: $800 at $10 per poster B: $800 at $5 per poster C: $750 at $10 per poster D: $750 at $5 per poster

Answers

Here is our profit as a function of # of posters
p(x) =-10x² + 200x - 250
Here is our price per poster, as a function of the # of posters:
pr(x) = 20 - x
Since we want to find the optimum price and # of posters, let's plug our price function into our profit function, to find the optimum x, and then use that to find the optimum price:
p(x) = -10 (20-x)² + 200 (20 - x) - 250
p(x) = -10 (400 -40x + x²) + 4000 - 200x - 250
Take a look at our profit function. It is a normal trinomial square, with a negative sign on the squared term. This means the curve is a downward facing parabola, so our profit maximum will be the top of the curve.
By taking the derivative, we can find where p'(x) = 0 (where the slope of p(x) equals 0), to see where the top of profit function is.
p(x) = -4000 +400x -10x² + 4000 -200x -250
p'(x) = 400 - 20x -200
0 = 200 - 20x
20x = 200
x = 10                         
p'(x) = 0 at x=10. This is the peak of our profit function. To find the price per poster, plug x=10 into our price function:
price = 20 - x
price = 10
Now plug x=10 into our original profit function in order to find our maximum profit:
p(x)= -10x^2 +200x -250
p(x) = -10 (10)² +200 (10) - 250
p(x) = -1000 + 2000 - 250
p(x) = 750

Marco wants to set up 12 small turbines with 3 blades each.If 4 wind turbines blades cost $79.64,how much will all the blade cost?

Answers

Hello!


If Marcos has 12 turbines with 3 blades / turbine, then 36 blades. If 4 blades cost $ 79.64, then how much do the 36 blades cost?

Let's make a simple three rule:

Blade ___ price

4 ----------- 79.64
36 --------- y


4 * y = 36 * 79.64
4y = 2,867.04
[tex]y = \frac{2,867.04}{4} [/tex]

y = 716.76

The 36 blades cost $ 716.76

If Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64 then $716.76 costs for all blades.

What is Equation?

Two or more expressions connected with an equal sign is called ad equation.

Given Marco wants to set up 12 small turbines with 3 blades each. If 4 wind turbines blades cost $79.64, then we have to find the cost of all blades.

Each turbine has 3 blades, so for 12 tubines we have

3×12=36 blades.

If 4 blades cost is  $79.64, then we have to find cost of 36 blades.

Let y be the cost of 36 blades.

4 /36= 79.64/y

Use cross multiplication,

4 * y = 36 * 79.64

4y = 2,867.04

y=716.76

Therefore 36 blades cost is $ 716.76.

the easiest way to determine the equation of this line is to 
1) determine the y-intercept, and 
2) use the given slope to come up with another point on the line.

Looking at the graph, you can easily see that the graph crosses the y-axis at (0,2).  Thus, the y-intercept is 2.  

Now let's determine the slope of this line:

Begin at the point (-4,0) (which happens to be the x-intercept).

Move 4 units from there to the right.  How many units UP must you then travel to reach the graph?  call this "m."

Then the slope is m/4.

Then the equation of the line is   y = mx + b, or

Jason is standing on the ground and throws a ball vertically upward with an initial speed of 80 ft/sec.  Its height after t seconds is given by h = 80t-16t^2 
a) How high does the ball go?  
b)  How many seconds does it take to reach maximum height?
c) When does the ball hit the ground?   

Answers

Hello, I think you are missing extra information, another formula to go with this problem. 
Using calculus,
the velocity equation will be the derivative of the h function that gives.
v=80-32t

At its highest point the velocity=0, so we set v=0 and solve for t.
0=80-32t
32t=80   t=2.5 seconds
the height at this point would be
h=80(2.5)-16(2.5)^2
h=200-16(6.25)=200-100=100
A) h=100ft

B) at t=2.5 seconds

The ball will take an additional 2.5 seconds to come back down. Therefore the total time for it to hit the ground would be 
C) 5 seconds.

How to add 3/5 and 1/10 in simplest form

Answers

Find a common denominator and then add.
3/5=6/10
6/10+1/10=7/10
to add these you must have a common denominator. In this case 10 will work because both 5 and 10 can evenly go into 10. Now whatever you multiplied the bottom by to get 10 you must do the same to the top. This is shown below:
3/5+ 1/10 = 6/10+ 1/10
You can now add these together to get 7/10. This is also in the simplest form.

   [tex] \frac{2}{5} [/tex] * 15 =  [(15 ÷ 5) * 2] = 3 * 2 = 6 .
___________________________________________
Method 2) 
___________________________________________

[tex] \frac{2}{5} [/tex] * 15 ;

= [tex] \frac{2}{5} [/tex] * [tex] \frac{15}{1} [/tex] ;

= [tex] \frac{2*15}{5*1} [/tex] = [tex] \frac{30}{5} [/tex] = 6 .
_________________________________________________

_________________________________________________
[tex] \frac{2}{5} [/tex] * 15 ;

= [tex] \frac{2}{5} [/tex] * [tex] \frac{15}{1} [/tex] ;

   → At this point, we can "cancel out" the "5" to a "1"; &
                            we can "cancel out" the "15" to a "3" ; 

                         → {Since:  "15 ÷ 5 = 3" ;  and since: "5 ÷ 5 = 1"}.

  → And rewrite as: = [tex] \frac{2}{1} [/tex] * [tex] \frac{3}{1} [/tex] ;

                    → At this point, we can rewrite as:

                                 " 2 * 3 " ;   and:  "2 * 3 = 6 " .

→ Alternately, we can continue as follows:

[tex] \frac{2}{1} [/tex] * [tex] \frac{3}{1} [/tex] ;

=  [tex] \frac{2*3}{1*1} [/tex] = [tex] \frac{6}{1} [/tex] = 6 .

[tex] \frac{2}{5} [/tex] * 15 ;

           = [tex] \frac{2}{5} [/tex] * [tex] \frac{15}{1} [/tex] ;

           = [tex] \frac{2*15}{5*1} [/tex] 

               →  At this point, we can "cancel out" the "15" in the numerator to a "3"; & we can "cancel out" the "5" in the denominator to a "1" ;
                 {Since:  "15 ÷ 5 = 3" ; and since:  "5 ÷ 5 = 1" ;

               → and rewrite as follows:

             We can rewrite as:    

→  [tex] \frac{2*3}{1*1} [/tex]   =  [tex] \frac{6}{1} = 6 .

Alternately, at the point when we have:

→  [tex] \frac{2*3}{1*1} [/tex]  ;  

→  We can ELIMINATE the "denominator" completely; 
Since the denominator, "(1*1)" is equal to "1" ; and since any value (e.g. the "numerator"); divided by "1" (e.g. the value of the denominator); equals the same value (e.g. that same value of the numerator);

Find the distance from the point (4, 1, −1) to the plane x − 2y + 2z + 3 = 0

Answers

I believe the answer is -17????
Distance from point (4,1,-1) to plane x-2y+2z+3 = 0 is 1. The formula for the distance from a point to a plane is d = abs(Ax + By + Cz + D) / sqrt(A^2 + B^2 + C^2) where d = distance (x,y,z) = coordinates of point A,B,C,D = coefficients of equation for the plane For this problem, the values for A,B,C,and D are A=1, B=-2, C=2, and D=3. So substituting the known values into the equation, we get: d = abs(1*x - 2*y + 2*z + 3) / sqrt(1^2 + (-2)^2 + 2^2) d = abs(1*4 - 2*1 + 2*(-1) + 3) / sqrt(1 + 4 + 4) d = abs(4 - 2 - 2 + 3) / sqrt(9) d = abs(3) / 3 d = 1

Let a, b, c, and d be constants. Describe the possible solution sets of the inequality ax+b

Answers

Final answer:

An inequality's solution set is determined by its specific properties. For a quadratic inequality, it can be solved by first finding the roots with the quadratic formula and then testing ranges between the roots to see where the inequality holds.

Explanation:

The question seems a bit incomplete, as there is no inequality provided related to constants a, b, c, and d. Typically, if we had a complete inequality, the solution set would depend on the specifics of the inequality. For instance, if we took a quadratic inequality, ax²+bx+c>0, or ax²+bx+c<0, we would solve it by finding the roots using the quadratic formula (-b ± √b² - 4ac) / 2a, which gives us the values of x where the expression equals zero, and testing regions determined by these roots to find where the inequality holds. However, without a specific inequality provided, it's difficult to describe the possible solution sets accurately.
