distance = time * speed
1 mile = time * 3.5 miles /56 minutes
so time = 56 minutes/3.5 = 16 minutes
Answer:
f(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x = 2, f(x) = f(2) = - 18 (component of y of the vertex)
c) VERTEX(2, - 18)
d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144
Hope this helps! :)
Answer
I do not think so.
Step-by-step explanation:
I don't know 1 but 2 can be 2.3 over 4.5 I think sorry if it's wrong but I hope it helps
