A graphing calculator shows the rocks are at the same height 1.5 seconds after they are released.
That height is 3.975 meters.
_____
f(x) = g(x)
-4.9x^2 +15 = -4.9x^2 +10x
15 = 10x . . . . . . . . . . . . . . . . . . add 4.9x^2
1.5 = x . . . . . . . . . . . . . . . . . . . divide by 10
f(1.5) = -4.9*2.25 +15 = 3.975
He buys 18 apples = £1.08
He can buy 9 bananas
Answer:
A=B
Step-by-step explanation:
Equation 1: 70% of A = 0.7a
Equation 2: 35% of B = 0.35a
Equation 3 = (Equation 2) • 2
Equation 3: 70% of B = 0.7a
Equation 3 = Equation 1
A = B
Tension seems the obvious answer here, but then we are left with x. Since the horisontal line on a graph is 'x'. The answer appears to be Tension X (Tension on X axis. Hope this helps.
