Participant A runs
2.75 laps in 5 minutes.
2.75/5 = 0.55 lap/minute

If x = minutes, and y = laps, then the equation for Participant A is
y = 0.55x

y = 0.3x and y = 0.5x represent a slower participant than A.

Participant A is slower than Participant B, so Participant B must run faster than Participant A.

y = 0.7x and y = 0.9x represent a faster race that y = 0.55x

Answer:
y = 0.7x
y = 0.9x

Differentiate the following function.<br> y=x(x^2+5)^2
dalvyx [7]
First, expand to make it easier
y=x(x^2+5)(x^2+5)
y=x(x^4+10x^2+25)
y=x^5+10x^3+25x
differentiation
y'=5x^4+30x^2+25 is the derivitive

Jane is building eight 3-legged stools. Each leg is 1/2 yard long. She can cut the legs from wooden rods that are sold in 2-yard
jonny [76]

Answer:

n = 6\,rods

Step-by-step explanation:

The total of legs needed to build the stools are:

x = (8) \cdot (3)

x = 24

Likewise the total length of the legs is:

L_{tot} = 24\cdot (0.5\,yd)

L_{tot} = 12\,yd

Lastly, the quantity of rods that needed to buy is:

n = \frac{12\,yd}{2\,\frac{yd}{rod} }

n = 6\,rods
