Answer:
120 cars
Step-by-step explanation:
The given function is
[tex]C(x)=0.5x^2-120x+21,481[/tex]
and its parent function would be
[tex]f(x)=ax^2+bx+c[/tex]
So,
[tex]a=0.5[/tex]
[tex]b = -120[/tex]
and
[tex]c = 21,481[/tex]
The minimum cost would be found using:
[tex]x = -\frac{b}{2a}[/tex]
So just input a and b into the function:
[tex]x= -\frac{-120}{2(0.5)}[/tex]
[tex]x=-\frac{-120}{1}[/tex]
[tex]x = 120[/tex]
Therefore there must be 120 cars made to minimize the cost.

Parallel lines r and s are cut by two transversals, parallel lines t and u.
Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of r and u, 13, 14, 15, 16.
How many angles are alternate exterior angles with angle 5?
Answer:
The alternate exterior angles with angle 11 are angle 13 and angle 5.
Step-by-step explanation:
Two angles are called Alternate exterior angles if
1. They are on the exterior side of parallel lines and
2. Lie on the opposite sides of the transversal line.
It is given that
[tex]r||s[/tex] and [tex]t||u[/tex]
From the figure it is noticed that the angle 13 and angle 5 are on the exterior side of parallel lines and they lie on the opposite sides of the transversal line.
Therefore alternate exterior angles with angle 11 are angle 13 and angle 5.

Given three consecutive odd integers, what is the greatest number if triple of the sum of thrice the third one and twice the first one is equal to 291? ( grid-in )
Let n be the smallest of these integers. The other two are then n + 2 and n + 4.
"triple of the sum of thrice the third one and twice the first one is equal to 291" is a long-winded way of saying
3 (3 (n + 4) + 2n) = 291
Solve for n :
3 (3n + 12 + 2n) + 291
3 (5n + 12) = 291
15n + 36 = 291
15n = 255
n = 17
Then the greatest of the three integers is n + 4 = 21.

Gina is buying 24 oranges. Two stores offer the following deals:
Store A: 12 oranges for $6.48
Store B: 5 oranges for $2.65
Gina can buy oranges individually.
How much will Gina save if she buys 24 oranges at Store B?
Show your work.
Answer:
She saves 24 cents by buying 24 oranges at store B
Step-by-step explanation:
Price per orange A = 6.48 / 12 oranges = .54 per orange
.54 * 24 oranges = 12.96 for store A
Price per orange B = 2.65 / 5 = .53 per orange
.53 * 24 oranges = 12.72 for store B
12.96 - 12.72 = .24 dollars (24 cents)

How many solutions does the equation 3x 6 = − 1 − 3 4x have? two zero one infinitely many
The nature of solutions to equations can be finite, infinite or no solution. The solution to the system of equation 3x + 6 = -1-3 + 4x is 10
Solution to system of equationsThe nature of solutions to equations can be finite, infinite or no solution.
Given the linear solution as shown:
3x + 6 = -1-3 + 4x
Collect the like terms
3x - 4x = -1 -3 -6
-x = -10
Multiply both sides by -1
-(-x) = -(-10)
x = 10
Hence the solution to the system of equation 3x + 6 = -1-3 + 4x is 10
