Answer:
Step-by-step explanation:
Given that at time t, the position of a body moving along the s-axis is sequalsnegative t cubed plus 15 t squared minus 72 t m
i.e. 
Velocity is nothing but s'(t) = derivative of s
and acceleration is s"(t) = derivative of v(t)
a) v(t) =0 when t = 4 or 6
b) 
a(t) =0 when t =5
c) Distance travelled by the body from 0 to 5 would be
i.e. 110 miles (distance cannot be negative)
Answer:
Step-by-step explanation:
A factor tree is not unique for a given number. Instead of expressing 36 as 2 × 18, we can express 36 as 6 × 6. Prime factorization of 36 using factor tree method is 2 × 2 × 3 × 3 = 2² × 3².
Answer:
x= 25/6 it is the same in both equations
3^2 + 10^2 = 109
square root of 109 = 10.4403065089
Answer:
A) 46 mph
Step-by-step explanation:
<em>Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.</em>
Distance = 354 miles
Time = 9: 50 am to 5: 30 pm
Time = 7 hours 40 minutes
<em>Step 2: Convert time to hours</em>
1 hour = 60 minutes
40 minutes = 60/40 = 2/3 hours
<em>Step 3: Find the speed</em>
Speed = Distance/Time
Speed = 354/7 + 2/3
Speed = 1062/23
Speed = 46.17 miles per hour rounded off to 46 mph
Therefore, A is the correct answer.
