Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
Answer:
120 Minutes
Step-by-step explanation:
24 minutes / 2 miles = 12 minutes / 1 mile
12 minutes / 1 miles = x minutes / 10 miles
Cross multiply
12*10/1 = x
120 / 1 = x
x = 120
Hope that helps!
You use pi times radius squared. Pi 15 squared=706.858 then take 706.858 and multiply it by the depth of 12. 706.858×12=8482.3 Cm squared. 8482.3 cm to liters is about 8.5 liters
