A planet has a circular orbit around a star. It is a distance of 65,000,000 km from the centre of the star. It orbits at an aver

guapka [62]

Answer:

Step-by-step explanation:

Orbit = 2*pi * r

r = 65000000 km

Orbit = 65000000 * 2 * 3.14

Orbit = 406 200 000 km

d = 406 200 000

s = speed = 65000 km / hr

t = time = d / s

t = 406,000,000 / 65000

t = 6280 hours.

1 day = 24 hours.

t = 6280 / 24 = 261.67 days

Answer:

$\frac{f(x+h)-f(x)}{h}$ $=2x + h$

Step-by-step explanation:

Given

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

Required

Determine: $\frac{f(x+h)-f(x)}{h}$

First, we calculate f(x + h)

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

$f(x+h) = (x+h)^2+2$

$f(x+h) = x^2+2xh+h^2+2$

So, we have:

$\frac{f(x+h)-f(x)}{h}$ $= \frac{x^2 + 2xh + h^2 + 2 - x^2 - 2}{h}$

$\frac{f(x+h)-f(x)}{h}$ $= \frac{x^2 - x^2+ 2xh + h^2 + 2 - 2}{h}$

$\frac{f(x+h)-f(x)}{h}$ $= \frac{2xh + h^2}{h}$

$\frac{f(x+h)-f(x)}{h}$ $=2x + h$

Two men walk at rates of 6 mph and 10 mph, respectively. Simultaneously, they started from the same place walking waking in oppo

VladimirAG [237]

Answer:

12.5 hours :)

Step-by-step explanation:

Let after t hours , the two men are 200 miles apart

So the distance traveled by fthe irst man is 6 miles

And the distance traveled by the second man is 10 miles

So the equation is 6t+10t=200

Therefore after 12.5 hours, they are 200 miles apart.

P.S. Please give me brainliest!
