The total purchase is $18.90.
What is the total purchase?A discount would reduce the cost of the purchase. A tax increases the cost of the purchase.
The first step is to determine the total cost of the items purchased.
Total cost = (cost of lb of cheese x lb bought) + (cost of sliced ham x lbs bought) + (cost of bread x loaves bought) + (cost of a bag of potato chips x number of bags bought) + (cost of one salsa container x number of containers bought)
(1.99 x 1/2) + (3 x 3.29) + (1.59 x 2) + (2 x $3) + (1.39 x 1) = $20.39
Since, the total cost is greater than $20 she qualifies for the 10% discount
Total cost after the discount = (1 - 0.1) x $20.39
0.9 x $20.39= $18.35
Cost after the tax = (1 + 0.03) x $18.35
1.03 x $18.35 = $18.90

A single 6-sided die is rolled twice. Find the probability of getting a 3 the first time and a 4 the second time. Express the probability as a simplified fraction
Answer:
[tex]\frac{1}{36}[/tex]
Step-by-step explanation:
The first roll. There are six possible answers (1,2,3,4,5,6), but of those 6 answers, there is only one that I want; 3. so, The probability of rolling a 3 is [tex]\frac{1}{6}[/tex]. There is the same probability for rolling a 4.
If I multiply these together I will find the probability that I am looking for.
[tex]\frac{1}{6}[/tex] x [tex]\frac{1}{6}[/tex] = [tex]\frac{1}{36}[/tex]

Column 3 is labeled bunkers with entries 2, 5, 1, 0, 2, 1. Column 4 is labeled difficulty level with entries moderate, moderate, easy, moderate, hard, moderate.
Which of the variables in the data set is a categorical variable?
hole number
yards
bunker
difficulty level
The categorical data in the table is the number of holes (option 1).
What is a categorical data?Categorical variables are variables that can only take on a fixed or a limited number of values. Categorical variables are examples of qualitative data.
Categorical variables can be binary. This mean that they can either have two values. An example of categorical variable is yes or no. Binary variables can also be called dichotomous variable. A categorical variable is polytomous if can have more than two values.
In this question, the maximum hole number possible is 18 holes. The number of holes cannot exceed this number. Thus, the hole number is limited or fixed. Thus, hole number is a categorical data.

Answer:
Choice A: 11
Step-by-step explanation:
We have x² - y² = 19
x² - y² = (x + y)(x-y)
So (x + y)(x-y) = 19
Since x and y are integers as per the first statement (x, y ∈ Z), we also have x + y = integer and x-y = integer
Take (x + y)(x - y) = 19
Since 19 is prime its only factors are 1 and 19
So we have two situations which can satisfy the above
Either x + y = 1 and x -y 19 or x + y = 19 and x -y = 1
1. Let's try x + y = 1 and x - y = 19
Adding both equations together gives us 2x = 20 (y-terms cancel)
==> x = 10 ==> 10 + y = 1 or y = -9
So 2x - 9 => 2(10) - (-9) = 20 + 9 = 29
This is not one of the choices so we can go on to the next case
2 Let's take x + y = 19 and x - y = 1
Adding these two equations gives us
2x = 20, x = 10 as before
Use 10 in the equation x + y = 19
==> 10 + y = 19
==> y = 19 - 10 = 9
2x - y ==> 2(10) - 9 ==> 20 - 9 = 11
So answer is choice A: 11
Why does the range of this function include negative values? What is the significance of the point where the graph crosses the horizontal axis?
The range is the set of y outputs. In this case, the range is the profit.
A negative profit means the company lost money. This is when the cost is larger than the revenue. For instance, if the revenue was $100 but the cost is $150, then the profit = revenue - cost = 100-150 = -50 to signal they lost $50.
Positive profit means the company made money.
The x intercept represents the break-even point. This is where the company neither loses money, nor gains money. The profit is $0 here.
Answer/Step-by-step explanation:
In order to open a restaurant you have to rent a venue, furnish and decorate it, hire a staff and buy food and drinks. Before serving (selling) any meals you have to spend a lot of money. This is why the negative y-values.
At the point where the line crosses the x-axis (horizontal axis) you now begin to have a positive output to your operation. If you sell enough meals, you will turn a profit. That is, you make enough money to pay all those start-up expenses and still have money left over to keep!
The region [tex]R[/tex] is bounded by the lines [tex]x=2[/tex], [tex]x=3[/tex], [tex]y=-1[/tex], and the curve [tex]y=\frac{1}{2+x^3}[/tex]. Suppose a solid is formed by revolving [tex]R[/tex] about an axis. Use the disk/washer method to set up the integral (or expression involving sums of integrals) giving the volume of the solid formed when [tex]R[/tex] is revolved about [tex]x=-5[/tex].
The curve intersects the vertical lines when
[tex]x=2 \implies y = \dfrac1{2+2^3} = \dfrac1{10}[/tex]
and
[tex]x=3 \implies y = \dfrac1{2+3^3} = \dfrac1{29}[/tex]
Split up the region into washers of thickness [tex]\Delta y[/tex].
For [tex]-1\le y\le\frac1{29}[/tex], the inner and outer radii of each washer will be constant, with outer radius [tex]x=3[/tex] and inner radius [tex]x=2[/tex]. Each washer in this interval will contribute a total volume of
[tex]\pi (3^2 - 2^2) \Delta y = 5\pi\,\Delta y[/tex]
For [tex]\frac1{29} \le y \le \frac1{10}[/tex], the washers will have a varying outer radius of length
[tex]y=\dfrac1{2+x^3} \implies x = \sqrt[3]{\dfrac1y - 2}[/tex]
and inner radius [tex]x=2[/tex]. Their volumes are
[tex]\pi \left(\left(\sqrt[3]{\dfrac1y - 2}\right)^2 - 2^2\right) \, \Delta y = \pi \left(\left(\dfrac1y - 2\right)^{2/3} - 4\right) \, \Delta y[/tex]
Let [tex]\Delta y\to0[/tex]. Then as the number of washers goes to infinity, the total volume of the solid converges to the definite integral
[tex]\displaystyle 5\pi \int_{-1}^{1/29} dy + \pi \int_{1/29}^{1/10} \left(\left(\dfrac1y - 2\right)^{2/3} - 4\right) \, dy[/tex]
The first integral is trivial, but the second one requires hypergeometric functions to evaluate exactly. With a calculator, we find the approximate volume to be 0.117884.
Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth.
5y2 - 8y = 2
The solution of y are 1.82 and -0.22
The general expression for quadratic equation is given as :
ax² + bx + c = 0
The quadratic formula of the above equation is given as
x = -b ± √b²-4ac / 2a
According to the question we have been the expression as
5y² - 8y = 2
Converting it into general expression we get
5y² - 8y - 2 = 0
Putting the required value in above quadratic formula we get
y = -(-8) ± √(8)² - 4*5*(-2) / 2*5
y = 8 ± √64 + 40 / 10
y = 8 ± √104 / 10
y = (8 ± 10.2)/10
y = 8 + 10.2 / 10 and y = 8-10.2 / 10
y = 18.2 / 10 and y = -2.2/10
y = 1.82 and y = -0.22
Hence the solution of y are 1.82 and -0.22

If JK = x + 8, KL = 10, and JL = 7x, what is JK?
Answer:
10 is the jk because x + 8 is 10
I hope it will help
Answer:
11 units
Step-by-step explanation:
It's clear that,
JL = JK + KL
Given that,
JK ⇒ ( x + 8 )
KL ⇒ 10
JL ⇒ 7x
So, by using these data we can make an expression like this.
JL = JK + KL
7x = x + 8 + 10
Now make x the subject and find the value of x.
7x = x + 8 + 10
7x = x + 18
7x - x = 18
6x = 18
6x/6 = 18/6
x = 3
And now let us find the value of JK.
JK ⇒ x + 8
To, find the value of JK we have to replace with 3.
JK ⇒ x + 8
JK ⇒ 3 + 8
JK ⇒ 11 units

The height above ground of a cannon is a function of the time since it was shot.
Question: When time equals 0, why is the height of the cannon ball not equal to 0? Describe the domain of this function. Describe the range.
The height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground
When time equals 0, why is the height of the cannonball not equal to 0?From the graph, we have the y-intercept to be
y-intercept = (0, y), where y > 0
This means that the graph starts above the origin
This in other words mean that the initial height of the cannonball is above the ground (e.g. it could be on a building)
Hence, the height of the cannonball not equal to 0 when time equals 0 because initial height of the cannonball is above the ground
Describe the domain and the range of this functionIn this case, the domain is from t = 0 till the ball lands on the floor, while the range is from the initial height of the cannonball till the maximum height
