To solve this problem you must apply the proccedure shown below:
1. You have the following quadratic equation, which is given in the problem above:
<span>2y^2+6y-8=0
2. So, to solve it, you can use the quadratic formula, which is:
y=(-b</span><span>±</span>√(b²-4ac))/2a
<span>
a=2
b=6
c=-8
3. When you susbtitute these values into the formula, you obtain:
y1=-4
y2=1</span>
Answer:
15 x p = 300 OR 15p = 300
Step-by-step explanation:
Diameter = 2*radius
14/2=7
Radius is 7in"
Circumference of circle formula: 2pi(radius)
2pi(7)= 43.98in of wire required so it can wrap around lamp exactly once.
