I need help with number 6 please provide a screenshot of the Desmos and any work on paper
Answer:
See below
Step-by-step explanation:
Graphing all three equations can be done on one DESMOS plot, but it gets very busy and cluttered. The attached image demonstrates an approach that simplifies the graph.
Enter the three equations and three inequalities separately into six DESMOS input boxes. Then I clicked off the color circles of the ones I didn't want to see, leaving only two visible at one time. Each pair represents one line of the function and limit for that function. Then find the intersection point for the values indicated in the second half of the equation.

Answer:
Design 1: $449.45
Design 2: $522.60
Design 3: $318.25
Design 3 as it's the cheapest
Step-by-step explanation:
Design 1
Area of a trapezoid = 1/2(a + b)h (where a and b are the bases and h is the height)
Given the slanted side = 3.5
Height = √(3.5² - 1²) = (3√5)/2
⇒ area of design 1 = 1/2(5 + 3) × (3√5)/2 = 6√5 = 13.42 m²
⇒ cost = 13.42 x 33.5 = $449.45
Design 2
Area of a triangle = 1/2 x base x height
Area of a rectangle = width x length
Area of a 6-sided regular polygon = 4 triangles + rectangle
⇒ area of design 2 = 4(1/2 × 1.4 × 2.0) + (2.5 × 4) = 15.6 m²
⇒ cost = 15.6 x 33.5 = $522.60
Design 3
Area of a trapezoid = 1/2(a + b)h (where a and b are the bases and h is the height)
⇒ area of design 3 = 1/2(3 + 2) × 2 + 1/2(3 + 1.5) × 2 = 9.5 m²
⇒ cost = 9.5 x 33.5 = $318.25

The amount of money in a bank account increased by 17.5% over the last
year. If the amount of money at the beginning of the year is represented by
n, which expression represents the amount of money in the bank account
after the increase?
An + 0.175n
B n + 17.5n
C 0.175n
D 17.5n
Answer:
1.175A
Step-by-step explanation:From the information given in the question, we are told that the amount of money that is in a bank account increased by 17.5% while the money at the beginning of the year is represented by A.
The expression that represents the amount of money in the bank account after the increase will be:
= A + (17.5% × A)
= A + (17.5/100 × A)
= A + (0.175 × A)
= A + 0.175A
= 1.175A

Find the probability of picking a green or orange marble from a bag
containing 5 green, 3 yellow, and 5 orange marbles.
Answer:
76.92%
Step-by-step explanation:
Green: 5
Orange: 5
Yellow: 3
First: 5 + 5 + 3 = 13
Now we need to find the probablility of picking an orange or green marble.
We need to divide the number of green and orange marbles put together by the total, 13.
10/13 = 76.92%
You have a 76.92% chance of picking either a green or orange marble.
Have an amazing day!!

What is random sample?Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.
A survey asked about the number of people who eat breakfast almost every day (B) and the number of people who buy cereal at least once a month (C).
The results of the survey are shown in the Venn diagram as,
Circles B and C overlap. Circle B contains 11, circle C contains 4, and the intersection contains 53. Number 23 is outside of the circles.Therefore, for circle B, it can be given as,
[tex]n(B)=11+53=64[/tex]
Similarly, for the circle C,
[tex]n(C)=53+4=57[/tex]
As the intersection of circle B and C contains 53,
[tex]n(BC)=53[/tex]
Now the probability that the person also buys cereal at least once a month, given that a randomly chosen person eats breakfast almost every day,
[tex]P(C|B)=\dfrac{P(BC)}{P(B)}\\P(C|B)=\dfrac{n(BC)}{n(B)}\\P(C|B)=\dfrac{53}{64}[/tex]

Hi There!
Given:
A placemat requires 30 feet of ribbonMandy has 200 feet of ribbonTo Find:
How many placemats can Mandy make, if she has 200 ft of ribbon?
Solve:
200÷30≈7
Thus, she can make 7 placemats.
Hope it helps & enjoy your day![tex]\huge\textbf{TheStarryNights}[/tex]
Answer:
C. 6 placemats
Step-by-step explanation:
Mindy has 200 feet of ribbon and each placemat requires 30 feet of ribbon.
Now, we need to divide 200 by 30.
200/30 ≈ 6.66666666667
Now, what whole number is before 6.66666666667?
6.
Now, what whole number is after 6.66666666667?
7.
What is 7 x 30?
210.
What is 6 x 30?
180.
Mindy has only 200 feet of ribbon, so she can't make 7 placements because 200 < 210, but she can make 6 placements because 200 > 180.

Briana is planning to spend March break at a winter resort. The cost of a 7-day snowboarding pass, including equipment rental, is $199. On the resort’s website, Briana reads that a daily pass with no equipment rental is $25.
How much is being charged for renting the equipment for the week?
Answer:
$24
Step-by-step explanation:
cost of a pass for a week (without equipment rental) = 7 x 25 = $175
Therefore, cost of just renting the equipment for the week = 199 - 175 = $24
ETA: As an algebraic equation
Let x = number of days
Let y = cost of renting the equipment for a week
y = 199 - 25x

What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

The americium is represented as 1. Every 432 years it decreases by 50%.
First half-life:
432 years.
[tex]1 \div 2 = 0.50[/tex]
0.50 (1/2) of americium remains after 432 years.
Second half-life:
[tex]432 \times 2 = 864[/tex]
[tex]0.5 \div 2 = 0.25[/tex]
0.25 (1/4) of the americium remains.
Third half-life:
[tex]432 \times 3 = 1296[/tex]
[tex]0.25 \div 2 = 0.125[/tex]
0.125 (1/8) of the americium remains.
Last half-life:

Jonathan first got the steps right, however, he was incorrect because he added the denominators together. Since the two denominators are the same, the sum will also have a denominator of 3, not 6. In his other steps, he was correct; 7 + 2 = 9, 2 + 2 = 4. Thus, making 9 4/3 or 10 1/3.

Given the polynomial 8x3 6x2 − 32x − 24, what is the value of the constant 'k' in the factored form? 8x3 6x2 − 32x − 24 = 2(x k)(x − k)(4x 3) 4 3 2 1.
Constant 'k' has the value in the form of factored after factorization, the provided polynomial equation is 2.
What is polynomial equation?Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).
The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.
The given polynomial equation in the problem is,
[tex]8x^3 +6x^2 - 32x - 24[/tex]
The factor of the polynomial equation are given as,
[tex]2(x+ k)(x - k)(4x +3)[/tex]
First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.
Take out the highest common factor 2, which can divide each term of the above equation (8, 6, -32, -24). Thus,
[tex]2(x+ k)(x - k)(4x +3)=2(4x^3 +3x^2 - 16x - 12)[/tex]
Take out the highest common factor to make the groups as,
[tex]2(x+ k)(x - k)(4x +3)=2(x^2(4x +3) - 4(4x + 3))\\2(x+ k)(x - k)(4x +3)=2(4x +3) (x^2 -4)\\2(x+ k)(x - k)(4x +3)=2(4x +3) (x^2 -2^2)[/tex]
Use the property of difference of the square for the (x²-2²) term as,
[tex]2(x+ k)(x - k)(4x +3)=2(4x +3) (x +2)(x-2)\\2(x+ k)(x - k)(4x +3)=2(x +2)(x-2)(4x +3)[/tex]
On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 2.
