The formula for a discriminant is b^2-4ac
so, (-7)^2 -4(3)(6) simplifies to 49-72 which equals -23
I would say the amount used would be at least 50 gallons because it makes most sense. Hope I helped :))
Pythagorean Theorem
c2 = a2 + b2
19^2 = a^2 + 11^2
361 = a^2 + 121
240 = a^2
A = 15.49
The distance traveled by the particle between the seconds t=1 and t=3 is 14 m.
<h3>
Distance traveled by the particle</h3>
The distance traveled by the particle is determined from the model of the particle's motion.
x(t) = t² - 6t
<h3>Distance traveled when t = 1</h3>
x(1) = (1)² - 6(1) = - 5 m
<h3>Distance traveled when t = 3</h3>
x(3) = (3)² - 6(3) = -9 m
<h3>Total distance traveled by t = 1 and t = 3</h3>
D = - 5 m - 9 m = - 14 m
|D| = 14 m
Thus, the distance traveled by the particle between the seconds t=1 and t=3 is 14 m.
