Break it into steps you can better understand
2 1/2 = 2.50cm
You want to take as many 2.50 cm pieces as possible so you cut one off.
58 - 2.50 = 55.5
and another
55.5-2.50 = 53
and so on...
Instead of subtracting like this, we use division
58 / 2.5
when you divide, this tells you how many 2.50cm pieces you can cut from a total length of 58cm
Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr
It would cost $6.87 and it’s an increase
The function <em>position</em> of the particle is s(t) = (1 / 12) · t⁴ + (7 / 6) · t³ + 3 · t² + (63 / 4) · t.
<h3>What are the parametric equations for the motion of a particle?</h3>
By mechanical physics we know that the function <em>velocity</em> is the integral of function <em>acceleration</em> and the function <em>position</em> is the integral of function <em>velocity</em>. Hence, we need to integrate twice to obtain the function <em>position</em> of the particle:
Velocity
v(t) = ∫ t² dt - 7 ∫ t dt + 6 ∫ dt
v(t) = (1 / 3) · t³ - (7 / 2) · t² + 6 · t + C₁
Position
s(t) = (1 / 3) ∫ t³ dt - (7 / 2) ∫ t² dt + 6 ∫ t dt + C₁ ∫ dt
s(t) = (1 / 12) · t⁴ + (7 / 6) · t³ + 3 · t² + C₁ · t + C₂
Now we find the values of the <em>integration</em> constants by solving the following system of <em>linear</em> equations:
0 = C₂
63 / 4 = C₁ + C₂
The solution of the system is C₁ = 63 / 4 and C₂ = 0. The function <em>position</em> of the particle is s(t) = (1 / 12) · t⁴ + (7 / 6) · t³ + 3 · t² + (63 / 4) · t.
