Ok so here we go!
a steam and leaf plot is very simple to figure out

Bob and John are 450 feet apart when they start running towards each other. Bob runs at a speed of 11 feet per second, and John
Elena L [17]

Answer:

18 s

Step-by-step explanation:

We are given that

Distance between Bob and John=450 feet

Speed of Bob=11ft/s

Speed of John=14 ft/s

We have to find the time after they will meet when they are travel towards to each other.

Total distance traveled by Bob and John in 1 s=11+14=25 ft

25ft covered by Bob and John in 1 s

1 ft covered by Bob and John in \frac{1}{25}s

450 ft covered by Bob and John  in \frac{1}{25}\times 450=18 s

Hence, they will meet after 18 s.

Consider the following. x = t2 − 2t, y = t5, 1 ≤ t ≤ 4 Set up an integral that represents the length of the curve. 4 1 dt Use yo
zavuch27 [327]

Answer:

L ≈ 1023.0562

Step-by-step explanation:

We are given;

x = t² - 2t

dx/dt = 2t - 2

Also, y = t^(5)

dy/dt = 5t⁴

The arc length formula is;

L = (α,β)∫√[(dx/dt)² + (dy/dt)²]dt

Where α and β are the boundary points. Thus, applying this to our question, we have;

L = (1,4)∫√[(2t - 2)² + (5t⁴)²]dt

L = (1,4)∫√[4t² - 8t + 4 + 25t^(8)]dt

L = (1,4)∫√[25t^(8) + 4t² - 8t + 4]dt

Using online integral calculator, we have;

L ≈ 1023.0562
