### At Bob's Burgers' grand opening, the owner gives each customer one spin on the spinner shown. All sections of the spinner are the same size. A.J. walks up to the spinner first. He hopes to win a free drink, a free dessert, or free fries. He says, “The probability that I get what I want is 1 out of 3, because there are 3 sections I want the arrow to land in.” Unfortunately, A.J. is incorrect. What is his actual probability of getting one of the three things he wants? What did he do wrong? How did you calculate the correct answer? Answer all three questions in complete sentences.

The actual probability of getting one of the three things he wants is 3/total number of sectios.
He thought it as since he needs to get 1 out of three items, so he did 1/3.
To get the correct answer, the number of items needed is divided with the total number of sections.

### Find the value of "a" for which the graph of the first equation is perpendicular to the graph of the second equation. 1) equation : y=a/3x-6 2) equation 4x+2y=6 Their is the same problems but different equation.1) 3y+ax=8 2)3/4x+2

Perpendicular lines will have negative reciprocal slopes. Example : if u r given a slope of 1/3, to find the negative reciprocal, flip the slope and change the sign. So the negative reciprocal of 1/3 is -3/1 or just -3. So slope 1/3 and slope -3 are perpendicular.
==================
equation 2 :
4x + 2y = 6
2y = -4x + 6
y = -2x + 3...the slope here is -2....a perpendicular line will have a slope of 1/2.

y = (a/3)x - 6......so we have to make a/3 = 1/2......1.5/3 = 1/2
so a = 1.5
===================
eq. 2 : 3/4x + 2
not sure what the entire equation is.....but it looks to have a slope of 3/4. That means a perpendicular line will have a slope of -4/3.

3y + ax = 9
3y = -ax + 9
y = (-a/3)x + 3.....therefore, a has to be 4

QUESTION POSTED AT 19/02/2020 - 01:41 PM

### Thomas buys a cardboard sheet that is 12 by 8 inches. Create an equation for this situation, find the zeros, and sketch the function. What is the size of the cutout he needs to make so that he can fit the maximum amount of food in the box? If Thomas wants a volume of 12 cubic inches, what size does the cutout need to be? What would be the dimensions of this box? Using complete sentences, explain the connection between the cutout and the volume of the box. Design an equation that would work for any cardboard sheet length, q, and width, p.

For the answer to the question above,

1. If we let x as the side of the square cut-out, the formula for the capacity (volume) of the food dish is:
V = (12 - 2x)(8 - 2x)(x)
V = 96x - 40x^2 + 4x^3
To find the zeros, we equate the equation to 0, so, the values of x that would result to zero would be:
x = 0, 6, 4

2. To get the value of x to obtain the maximum capacity, we differentiate the equation, equate it to zero, and solve for x.
dV/dx = 96 - 80x + 12x^2 = 0
x = 5.10, 1.57
The value of x that would give the maximum capacity is x = 1.57

3. If the volume of the box is 12, then the value of x can be solved using:
12 = 96x - 40x^2 + 4x^3
x = 0.13, 6.22, 3.65
The permissible value of x is 0.13 and 3.65

4. Increasing the cutout of the box increases the volume until its dimension reaches 1.57. After that, the value of the volume decreases it reaches 4.

5. V = (q -2x) (p - 2x) (x)

### In the figure below, CEF is an equilateral triangle. Points B, C and E are collinear; Points A, C and F are collinear; g = 40 degrees; and k = 45 degrees. Find angle l. Show all work.

There exists the same question with the figure as shown in the attachment.

The given are:
g = 40 degrees
k = 45 degrees

angle of " l "

So this is how to solve this:

Step 1:
Since CEF is an equilateral triangle, then each has 60 degrees.
i is equal to l because they are opposite angles

Step 2:
angle l is inside CEF, then the value of angle l is 60

### How do you find the Domain of a function

There are different way but I will give you 2 ways;
1. Learn the definition of the domain. The domain is defined as the set of input values for which the function produces an output value. In other words, the domain is the full set of x-values that can be plugged into a function to produce a y-value.
---
2. Learn how to find the domain of a variety of functions. The type of function will determine the best method for finding a domain. Here are the basics that you need to know about each type of function, which will be explained in the next section:
A polynomial function without radicals or variables in the denominator. For this type of function, the domain is all real numbers.
A function with a fraction with a variable in the denominator. To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation.
A function with a variable inside a radical sign. To find the domain of this type of function, just set the terms inside the radical sign to >0 and solve to find the values that would work for x.
A function using the natural log (ln). Just set the terms in the parentheses to >0 and solve.
A graph. Check out the graph to see which values work for x.
A relation. This will be a list of x and y coordinates. Your domain will simply be a list of x coordinates.

### I need help finding q'(7) where q(x) = f(x)/g(x) because: F is a zig zag line and at x = 7 the coordinates are: (7,5) however the slope is negative on the left and positive on the right so I can't use your regular slope form to figure out how to find the derivative. g(x)'s slope is .5 at the point, where the point is equal to (7, 2.5).

Remember the difference quotient
the deritivie of f(x)/g(x) is
so
q'(7)=
g(7)=2.5
g'(7)=0.5
f(7)=5
so
q'(7)=
q'(7)=
now find the slope of f(x) at x=7
take the deritive and evaluate
(try googling a deritive calculator)

basically
just find the slope of f(x) at x=7 (that is the slope at that specitific point, not for the whole graph)

### Anya makes 14 baskets during her game. some of these baskets were worth 2 points and others worth 3 points. in total, she scored 30 points. write and solve a system of equations to find how many 2 pointes baskets she made

Let the number of 2 points be x, and the number of 3 points be y.

Therefore x + y = 14 .....(i)

2*x + 3*y = 30 .....(ii)

x + y = 14

2x + 3y = 30

From (i),  x = 14 - y,  substitute this into (ii)

2*(14 - y) + 3y = 30

28 - 2y + 3y = 30

28 + y = 30

y = 30 - 28 = 2

y = 2,

x = 14 - y = 14 - 2 = 12,  x = 12.
