If the velocity of a bicycle is 10 m/s how long will it take to cover a distance of 18 km<br>

Sergeeva-Olga [200]

Answer:

time taken=1800 seconds

Step-by-step explanation:

velocity=v=10m/s

distance=S=18km=18×10³m=18000m

t=?

as we know that

velocity= $\frac{distance covered}{time taken}$

velocity×time taken=distance covered

now here we have to find time

time taken= $\frac{distance covered}{velocity}$

time taken= $\frac{18000m}{10m/s}$

time taken=1800seconds

Restrict the domain of the function f(x)=(x-2)to the power of 2 so it has an inverse. Then determine its inverse function.

nata0808 [166]

Answer:

Step-by-step explanation:

Given is a function

$f(x) =(x-2)^2$

This function is a parabola with vertex at (2,0) and axis of symmetry is x=2

Hence for x<2 the curve would be reflection of x>2

To get inverse we must get one to one funciton only.

So restrict the domain of f(x) to $[2,∞)$

Then we have f(x) as one to one with domain x≥2 and range is R+

$f^{-1} (x)=+\sqrt{x} +2$

For this inverse domain is R+ and range is $[2,∞)$
