Answer: The first hour is free, and the rest charges is $2.50
Let x be the time.
Let y be the total
Your equation will look like
When x < 2, y = 0
When x > 1, y = $2.50(x)
So:
1 < x < ∞ for hours, then equation will look like:
y = total amount
$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.
$2.50x - $2.50 = y should be your equation.
hope this helps
Step-by-step explanation:
Rotation about a point does not change any dimensions. C'D' = CD = 2.8 units.
Answer:2/pi
Step-by-step explanation:
First, name the points. Top Left will be A, Top Right will be B, Bottom Right will be C, and Bottom Left will be D. Now, the area of ABCD is 4. Then, we have to find the area of the circle. The center to the midpoint of AB is 1. The length of the midpoint of AB to B is 1. So, using the Pythagorean Theorem, it will be 1^2 + 1^2 = 2, then it will be sqrt2. Finding the area of the circle will be easy now that we have the radius. sqrt2*sqrt2*pi = 2pi. So, it will be 4/2pi, and simplified, it will be 2/pi.
Answer:
(x-1)(x+5)=0
x=1; x=-5
Step-by-step explanation:
x²+4x=5
x²+4x+2²=5+2²
(x+2)²=3²
(x+2)²-3²=0
(x+2-3)(x+2+3)=0
(x-1)(x+5)=0
(x-1)=0 ; x=1
(x+5)=0; x= - 5
