Answer:
x=3/2, x=-4
Step-by-step explanation:
2x^2 + 5x - 12
First lets see if we can factor this
(2x ) ( x )
-12 = -1*12 1*-12
- 2*6 2 * -12
- 3*4 3 * -4
2 * one of these pairs - the other pair = +5
2*4 -3 = 5
Put the -3 in the first spot and the 4 in the second spot
(2x-3) ( x+4)
Using the zero product property
2x-3 =0 x+4=0
2x=3 x=-4
x = 3/2
Answer:
2x + 1 = 15
Step-by-step explanation:
The arc length between each car is 18.84 ft
<h3>
How to get the length of an arc?</h3>
For a section defined by an angle θ in a circle of radius R, the length of the arc is given by:
A = θ*R
A complete circle has an angle of 2π. Now, if the circle has 25 cars, then it has 25 sections, so the angle that defines each one of these sections is:
θ = (2π/25)
And the diameter of the circle is 150ft, so the radius (half of that) is:
R = (150ft)/2 = 75 ft
Then the length of the arc:
L = (2π/25)*75 ft = 18.84 ft
