Answer:

3.86 hours equation km/70=h

Step-by-step explanation:

We know that the bus started 300 km away from Orlando, and now it is 30 km away from Orlando. 300-30=270

We also know that the bus is driving 70 km per hour

In order to find how long it has taken the bus to travel the 270 km you need to divide 270 by 70.

300-30=270

270 divided by 70= 3.86 hours

The equation would be km/70=h

What does range mean?
AveGali [126]

Answer:

Hey there!

The range is the possible y-values of any function. That's the definition, but identifying range takes practice, so let me know if you need any help with that.

Hope this helps :)

The harmonic motion of a particle is given by f(t) = 2 cos(3t) + 3 sin(2t), 0 ≤ t ≤ 8. (a) When is the position function decreas
iren [92.7K]

For the last part, you have to find where f'(t) attains its maximum over 0\le t\le8. We have

f'(t)=-6\sin3t+6\cos2t

so that

f''(t)=-18\cos3t-12\sin2t

with critical points at t such that

-18\cos3t-12\sin2t=0

3\cos3t+2\sin2t=0

3(\cos^3t-3\cos t\sin^2t)+4\sin t\cos t=0

\cos t(3\cos^2t-9\sin^2t+4\sin t)=0

\cos t(12\sin^2t-4\sin t-3)=0

So either

\cos t=0\implies t=\dfrac{(2n+1)\pi}2

or

12\sin^2t-4\sin t-3=0\implies\sin t=\dfrac{1\pm\sqrt{10}}6\implies t=\sin^{-1}\dfrac{1\pm\sqrt{10}}6+2n\pi

where n is any integer. We get 8 solutions over the given interval with n=0,1,2 from the first set of solutions, n=0,1 from the set of solutions where \sin t=\dfrac{1+\sqrt{10}}6, and n=1 from the set of solutions where \sin t=\dfrac{1-\sqrt{10}}6. They are approximately

\dfrac\pi2\approx2

\dfrac{3\pi}2\approx5

\dfrac{5\pi}2\approx8

\sin^{-1}\dfrac{1+\sqrt{10}}6\approx1

2\pi+\sin^{-1}\dfrac{1+\sqrt{10}}6\approx7

2\pi+\sin^{-1}\dfrac{1-\sqrt{10}}6\approx6

Anna [14]

Answer:

-\sqrt{11}

Step-by-step explanation:

As square root value is written with both + and - signs

In Given case:

A polynomial has root \sqrt{11}

= ±3.316

Also -\sqrt{11}

= ±3.316

Hence -\sqrt{11} is also root of the polynomial!
