Answer:
c = 4 A
Step-by-step explanation:
The given function P(c) = - 15 c (c-8) is actually quadratic function:
P(c) = - 15c² + 120c or parabola
The standard form of a quadratic function is:
y = ax² + bx + c
For which x is the maximum of the parabola we can find with this formula
x = - b/2a
in this case a = -15 and b = 120 and input variable is current c
c = - 120/(2 · (-15)) = - 120/ (-30) = 4 A
c = 4 A

ANSWER: 46.8
39% of 120
The word "of" means multiplied. So you will have to multiply 39% x 120
To do that, first step is to change the percent (39%) into a decimal
39% = 0.39 (You move the decimal twice to the left, not right)
There's an invisible decimal behind 9 so ALWAYS move it twice.
= 39(.)⇒ 0.39
Then your final step is to multiply
120 x 0.39
1 2 0
x 0 . 3 9 ← notice this decimal
_______ ∨
1 0 8 0 ∨
+ 3 6 0 0 ∨
_______ ∨
4 6 8 0 There's an invisible decimal before the 0. Move that decimal two times to the left. 4680(.)⇒ 46.8
I'm assuming this is a math question and all the tents equal the same thing, so to find the price for one tent, we would divide 40/3
Each tent is about $13.33

Answer:
The coordinates of ABCD after the reflection across the x-axis would become:
Step-by-step explanation:
The rule of reflection implies that when we reflect a point, let say P(x, y), is reflected across the x-axis:
- x-coordinate of the point does not change, but
- y-coordinate of the point changes its sign
In other words:
The point P(x, y) after reflection across x-axis would be P'(x, -y)
P(x, y) → P'(x, -y)
Given the diagram, the points of the figure ABCD after the reflection across the x-axis would be as follows:
P(x, y) → P'(x, -y)
A(2, 3) → A'(2, -3)
B(5, 5) → B'(5, -5)
C(7, 3) → C'(7, -3)
D(5, 2) → D'(5, -2)
Therefore, the coordinates of ABCD after the reflection across the x-axis would become:
