A private museum charges $40 for a group of 10 or fewer people. A group consisting of more than 10 people must, in
addition to the $40, pay $2 per person for the number of people above 10. For example, a group of 12 pays $44. The
maximum group size is 50.
a) How much does a group of 16 pay?
b) Find a formula for the cost function.
c) What are the domain and range of the cost function? (Hint: Use the graph on the calculator)
Answer:
i hope this helpes
Step-by-step explanation:
a) A group of 16 pays $40 + ($2 x (16 - 10)) = $40 + $6 = $46.
b) The cost function can be represented as C(x) = 40 + 2(x - 10) for x > 10 and C(x) = 40 for x <= 10, where x is the number of people in the group and C(x) is the cost for the group.
c) The domain of the cost function is all non-negative real numbers less than or equal to 50 (0 <= x <= 50), since the maximum group size is 50. The range of the cost function is all non-negative real numbers greater than or equal to 40 (C(x) >= 40), since the minimum charge for a group is $40.
Answer:
a) $52
b) C(x) = 40 + 2x, if x > 10 and x ≤ 50
C(x) = 40, if x ≤ 10
c) Domain = {x ≥ 1 and x ≤ 50}
Range = { from 40 to 140}

Switch sides:lydia has money in two savings accounts one rate is 8% and the other is 12% if she has $350 more in 12% account and the total interest is $336 how much is invested in each savings account
The required amount invested in accounts with 8% and 12% are $1470 and $1820 respectively.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Lydia has money in two savings accounts one rate is 8% and the other is 12% and the total interest is $336. Let the amount invest in accounts be x and y respectively.
According to the question,
0.08x + 0.12y = 336 - - - - - -(1)
Again,
she has $350 more in 12% account
y = x + 350 - - - - - -(2)
Put y in equation 1,
0.08x + 0.12[x + 350] =336
0.08x + 0.12x + 42 = 336
0.20x = 336 - 42
x = 294/0.20
x = $1470
Now
y = 1470 + 350

The function that is represented by the graph is y = ∛(x + 3) + 3.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The general form of a cube root function is -
y = a∛(x - h) + k and the parent graph is y = ∛x.
So the parent function is found.
The coordinate point for the parent function is -
(-1,-1) , (0,0) and (1,1).
In the graph it can be seen that the coordinate points are -
(-4,2), (-3,3) and (-2,4)
So the graph is first moved 3 units up and then moved three units left.
So, the coordinated become - (x + (-3) , y + 3)
So, the function that represents the graph is -
y = ∛(x + 3) + 3
Therefore, the function is y = ∛(x + 3) + 3.

Write a story problem that can be represented by 8/3÷4 and explain why the division makes sense
A baker had 24 cupcakes and wanted to divide them equally among 8 friends. How many cupcakes would each friend receive?
The problem can be represented by 8/3 ÷ 4, where 8 represents the number of friends, 3 represents the number of cupcakes each friend should receive, and 4 represents the number of groups the cupcakes should be divided into.
The division makes sense because first, we need to find out how many cupcakes each friend should receive, which is 24 ÷ 8 = 3. Then, we divide the number of cupcakes each friend should receive by the number of groups to find out how many cupcakes each group should receive, which is 3 ÷ 4 = 0.75 cupcakes per group.

What is the linear equations?
A linear equation is a mathematical equation that represents a straight line when graphed on a coordinate plane. It has the form of ax + b = y, where a and b are constants and x and y are variables. The coefficient "a" determines the slope of the line, and the constant "b" determines the y-intercept.
The elimination method is a method of solving a system of linear equations by adding or subtracting the equations to eliminate one of the variables.
Here is the solution for the system of equations 2x - 2y = 2 and 5x + 2y = 12 using the elimination method:
Multiply the first equation by 5: 10x - 10y = 10
Add the two equations: 15x - 8y = 22
Solve for x by dividing both sides of the equation by 15: x = 22/15 = 11/5
Substitute the value of x back into one of the original equations to solve for y:
2x - 2y = 2
2(11/5) - 2y = 2
22/5 - 2y = 2
22/5 - 2y = 2
22/5 = 2 + 2y
22/5 - 2 = 2y
20/5 = 2y

which of these shapes below is an enlargement of shape x by a scale factor of 2
A scale factor consists of two or more shapes who look the same but have different scales or measures. A scale factor of 2 means that the new triangle is two times the size of the original.
If we look at shape x, we can see it has a base of 4, and a height of 3. If we also know that a scale factor of two means that the new shape will be twice as large, we can use an equation that looks like this:
(Base/height × scale factor = new base length)
4 × 2 = 8 (b)3 × 2 = 6 (h)Now that we have these numbers, we can take them and see which shape matches the new length.
Shape A has a base of 6, and a height of 5.Shape B has a base of 6, and a height of 8.Shape C has a base of 8, and a height of 8.Shape D has a base of 8, and a height of 6.Shape E has a base of 6, and a height of 6.Shape F has a base of 8, and a height of 6.Shape D has a base of 8 and a height of 6, meaning that it has a scale factor 2 compared to shape x.
