That means that it has 2 complex roots, and it has no x intercepts, means that it doesn't touch the x axis at all
Step-by-step explanation:
(example)
Think of it this way:
If joe caught 1 fish only
and bonita caught four more than joe
that means that she caught 5 fish in total.
(for the question)
This means that Bonita caught four more fish than Joe.
j + 4 = bonita
j = joe
Answer:
Step-by-step explanation:
Let b= number of people per bus
10b + 5 > 450
10b > 445
b > 44.5
Minimum per bus is 45 students
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
For this case we have the following equation of motion:
h (t) = -16t ^ 2 + 90t
Equaling the equation to zero we have:
-16t ^ 2 + 90t = 0
We look for the roots of the polynomial:
(t) (- 16t + 90) = 0
t1 = 0 (initial position)
t2 = 90/16 = 5.625 s (time it reaches the ground again)
Answer:
it will return to the ground in:
t = 5.625 s
