Answer 1

Answer:

Step-by-step explanation:

The task is to draw the parabola of the equation [tex]x^{2} -4x+4[/tex] on the given graph.

The first step we can take to doing this is to use the table on the left hand side to work out our x and corresponding y-values to use as plotting coordinates. To do this you want to substitute the given value for x which will give you a corresponding y-value.

E.g:

x | [tex]x^{2} -4x+4[/tex]      | y

0 | [tex](0)^{2} -4(0)-4[/tex] | -4

Here we have gotten the coordinates (0, -4) so this will be a point on the graph.

Repeat with all other values on the table and you should get a bunch of dots which lead upwards in a curved line from a point. Extend the lines to form a parabola shape (A u-shape).

Once you have drawn the graph, label the parts.

Roots: The places where the line crosses the x-axis

Vertex: The lowest point of the parabola

Line of symmetry: The vertical line in which the parabola reflects/ is the same either side (Has equation x=_).

y-intercept: The point where the line crosses the y-axis.

Hope this helped!

5) Amber picked fruits from her family's fruit trees and put them into baskets. She put 10 apples into each of 4 baskets, 10 oranges into each of 3 baskets, and 12 peaches into each of 5 baskets. How much fruit did she pick in all?

Answers

Total apples.

10(4)40

Total oranges

10(3)30

Total peaches

12(5)60

Total fruits

60+40+30130

Answer:

130

Step-by-step explanation:

We have given in the question 'she put 10 apples into each of 4 baskets.

Into = Multiply

we have to Multiply 10 with 4

=> 10 × 4

=> 40 Apples

Similarly, in the case of oranges we have to Multiply 10 with 3

=> 10 × 3

=> 30 Oranges

Same method will be followed to find the number of peaches that she picked .

=> 12 × 5

=> 60 Peaches

Total fruits Amber picked = Number of apples + Number of oranges + Number of peaches

=> Total fruits = 40 + 30 + 60

=> Total Fruits = 130 .

You are in charge of purchasing breakfast for an upcoming service activity involving about 50 people.

You have the choice to pick one of the following food items:

donuts ($0.30/each)
muffins ($0.50/each)
bagels ($0.40/each)
You have the choice to pick one of the following drinks:

individual cartons of milk or chocolate milk ($0.50/each)
individual bottles of orange juice or apple juice ($0.75/each)
You must stay within a budget of $100.

Write the following in your notebook.

What food item did you choose? What drink did you choose? Why?
Write an inequality to represent the cost of the items (less than or equal to $100) in standard form. Use x to represent the number of food items and y to represent the number of drinks.
Solve the inequality for y (slope-intercept form). Interpret the slope in context of the drinks and food items that are being purchased.
Graph the inequality and describe your graph and the process you used; for example, is your line dotted, solid, or shaded up or down? What does the shaded region represent?
What are the x and y-intercepts? Explain what these would represent in this situation.
What are the domain and range in this problem? Explain why you would or would not use the minimum and maximum values of the domain and range. How are the domain and range in the context of this problem different from the domain and range of any linear equation? What are the limits?

Answers

The limits of the domain and the range are 0 to 200, respectively; and you would use the minimum and maximum values of the domain and range because the graph of the inequality uses a solid line.

The items chosen

The items selected here could be any of the listed drinks and food items.

To solve this question, we use the following selection:

Muffins ($0.50/each) -- xindividual cartons of milk or chocolate milk ($0.50/each) -- yBudget of $100

The inequality of the cost of items

In this case, we use the less than or equal to inequality.

So, we have:

0.5x + 0.5y ≤ 100

Solve the inequality for y (slope-intercept form).

In (b), we have:

0.5x + 0.5y ≤ 100

Subtract 0.5x from both sides

0.5y ≤ -0.5x + 100

Divide through by 0.5

y ≤ -x + 200

This means that the slope is -1, and it means that for every food item bought, there is a decrement of 1 in the drink.

The graph of the inequality

See attachment for the graph of the inequality

The features of the graph include

Straight and solid lineIt is shaded downThe shaded region represents the acceptable solutions

What are the x and y-intercepts?

From the attached graph, we have:

x-intercept = 200y-intercept = 200

This means that you can buy 200 food items, when you buy no drinks or buy 200 drinks when you buy no food item

What are the domain and range in this problem?

These are the acceptable x and y values of the graph.

From the attached graph, we have:

Domain: 0 ≤ x ≤ 200Range: 0 ≤ y ≤ 200

The domain and range are different from the domain and range of any linear equation because the domain and the range of a linear equation is the set of all real numbers, while this domain and range are limited to 0 to 200

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan.

This percentage is known as the interest rate on the loan.

Brendon walsh wants to borrow $50,000

P = $50,000

The interest rate is 6%

and the term is for 5 years

S.I. = (P*R*T)/100 = (50000*6*5)/100 = 15,000

D)You infer that the mean weight of catfish in the lake is exactly to 2.2 pounds.

Answer:

C)

Step-by-step explanation:

It can't be A or B because the samples from 50 fish definitely wouldn't be equal to ALL the fish ever.

And it (more so) can't be D because you are finding the mean. that means that some catfish could weight 1 pound, and another could weigh 4, they would just cancel out.

Answer:

If the sum is 7, the vacation destination will be Alaska.

If the sum is 9, the vacation destination will be New Mexico.

If the sum is 8, 10 or 12, the vacation destination will be Puerto Rico.

Step-by-step explanation:

Create a sample space for the 2 spins (see attached).

From the sample space, the probabilities are:

P(sum is 6) = 4/16P(sum is 7) = 4/16P(sum is 8) = 1/16P(sum is 9) = 4/16P(sum is 10) = 2/16P(sum is 12) = 1/16

Therefore, to make a fair decision:

As the sum of 6, 7 and 9 each have equal probabilities (4/16), they should each be attritbuted to one destination.

As the sum of 8, 10 and 12 combined equal the same probability as the sum of 6, 7, and 9 individually, the sum of 8, 10 and 12 should be assigned to one destination combined.

Solution

If the sum is 6, the vacation destination will be London.

If the sum is 7, the vacation destination will be Alaska.

If the sum is 9, the vacation destination will be New Mexico.

If the sum is 8, 10 or 12, the vacation destination will be Puerto Rico.
