Answer:
151.6
Step-by-step explanation:
The velocity wouldd be 75.8 times 2
Assuming that the car is travelling at constant acceleration, follows the equation:
v = (v_in) + at
where v = velocity
v_in = initial velocity, (at t = 0)
a = acceleration
t = time
Given the conditions, v = 51 at t = 3, and v = 59 at t = 5
Eqn 1: 51 = (v_in) + a(3)
Eqn 2: 59 = (v_in) + a(5)
Solving for v_in and a (using a calculator)
v_in = 39
a = 4
therefore the equation for the motion of the car is:
v = 39 + 4t
This equation can be plotted using excel or wolframalpha.

we know that 9*9 = 81, so let's start there.
0.9 * 0.9
one amount has 1 decimal, the second amount has another decimal, so in the product, we must have two decimals, let's do the multiplication without the dot.
09 * 09 = 81
but we must have two decimals, so that becomes 0.81.
0.09 * 0.9
here we do the same, the multiplication without the dot, and then we add as many decimals, in this case is 3 decimals, first term has 2 and the second term has 1 decimal, so the product must have 3 decimals.
009 * 09 = 81
getting those 3 decimals.......... 0.081.
0.009 * 0.9
here we do the same
0009 * 09 = 81
the product needs 4 decimals, so................ 0.0081.
0.009 * 0.09
we do the same here
0009 * 009 = 81
since the product needs 5 decimals................. 0.00081.
I think this is the answer
