Answer:

d/dt(dx/dt)=K(dx/dt)^2

Step-by-step explanation:

Since, a is proportional to v^2; and a=d/dt(dx/dt) and v= dx/dt since they are instantanious acceleration and velocity respectively.

K=(d^x/dt^2)(dt/dx)^2

How many revolutions will a car wheel of 30in make as the car travels 1 mile? (1 mile = 5280ft)?
Nataliya [291]
30inc=76.2cm 
76.2*pi=76.2pi
1cm=0.0328084 foot
1 mile=<span>5280 ft
</span>5280/0.0328084=160934.4
1 mile=160934.4 cm
160934.4 /76.2pi=672.27
672 revolutions i think

Find the value of z.
AVprozaik [17]

Answer:

  z = 110°

Step-by-step explanation:

Angles z and the one marked 70° form an linear pair, hence are supplementary.

  z = 180° -70° = 110°

<h3>Angles where chords cross</h3>

The angle made by two chords is half the sum of the arcs intercepted by those chords. Here, that means ...

  70° = 1/2(60° +x)   ⇒   x = 140° -60° = 80°

The arc w completes the circle of 360°, so we have ...

  w +x +79° +60° = 360°   ⇒   w = 360° -219° = 141°

Finally, z is the average of w and 79°:

  z = (w +79°)/2 = (141° +79°)/2 = 110° . . . as above
