the height of a bottle rocket, in meters, is given by the function s(t)=−9t2+103t+403. find the average velocity of the bottle r

zaharov [31]

The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

The given parameters;

s(t) = -9t² + 103t + 403
time interval (4.499, 4.5), and (4.5, 4.501)

The average velocity of the bottle rocket over the intervals is calculated as follows;

when the interval = [<em>4.499, 4.5</em>]

$s(4.499)= -9(4.499)^2 + 103(4.499) + 403 = 684.22 \ m\\\\s(4.5) = -9(4.5)^2 + 103(4.5) + 403 = 684.25 \ m$

$v = \frac{\Delta \ s}{\Delta \ t} = \frac{684.25 - 684.22}{4.5 - 4.499} = 30 \ m/s$

when the interval = [<em>4.5, 4.501</em>]

$s(4.5) = -9(4.5)^2 + 103(4.5) + 403 = 684.25 \ m\\\\s(4.501) = -9(4.501)^2 + 103(4.501) + 403 =684.27 \ m\\\\v= \frac{684.27 - 684.25}{4.501-4.5} \\\\v = 20 \ m/s$

The instantaneous velocity of the bottle rocket at time t=4.5;

$v = \frac{d \ s(t)}{dt} = -18t + 103\\\\v(4.5) = -18(4.5) + 103\\\\v(4.5) = 22 \ m/s$

Thus, the average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.

What is the explicit rule for this geometric sequence? 29,23,2,6,.

solong [7]

The explicit rule for this geometric sequence 29,23,2,6, is n = 29 × (29/23)^(n - 1)

<h3>How to write explicit rule</h3>

First term, a = 29

Second term, a×r = 23

23 = 29 × r

23 = 29r

r = 29/23

Common ratio, r = 29/23

The explicit formula is given by

nth term = ar^(n - 1)

n = 29 × (29/23)^(n - 1)

Where,

nth term = number of terms

What would you do if you were born during World War Two

Nutka1998 [239]

It depends on what country I'm living in. If i lived in a place that Germany took over, I'd either go in hiding or flee. If i was in a place that Germany had no control over, I would do several things. I'd get as many jobs as I could and take any job that I could. I would do this because many things would be scarce during the war and therefore expensive. I would also do this to try and get home with a bomb shelter nearby with supplies. Then, I'd make sure I have a bag packed lightly with certain necessities in case I would have to quickly evacuate.
