Melissa launches a rocket from a 3-meter-tall platform. The height, h, of the rocket, in meters, can be modeled by the given gra
Pachacha [2.7K]
We can model the function between a and b as a linear function of negative slope because it is a short interval and the change is not very significant.
 We have then that the average rate of change in that interval is:
 m = (f (a) - f (b)) / (a-b)
 Substituting the values:
 m = (34.25 - 26) / (2.5-3.6)
 m = -7.5
 Negative, because the function decreases in that interval.
 Answer:
 a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds is:
 m = -7.5 m / s

mridul jogs around a rectangular park of 100m by 80m at the rate of 9km per hour. how much time will he take in jogging 6 rounds
anyanavicka [17]

Answer:

14minutes

Step-by-step explanation:

first you need to find the distance which you must find the perimeter P=100+80+100+80

=360 so you multiple it by 6 to get

=2160meters

so you need to convert the meters to kilometers

which is 1000m =1km

what about 2160m you cross multiply

to get 2.16km.

<em>so</em><em> </em><em>th</em><em>e</em><em> </em><em>di</em><em>stance</em><em> </em><em>repre</em><em>sent</em><em> </em><em>D</em><em>=</em><em>2</em><em>.</em><em>1</em><em>6</em><em> </em><em>km</em>

<em> </em><em> </em><em> </em><em>an</em><em>d</em><em> </em><em>spee</em><em>d</em><em> </em><em>represent</em><em> </em><em>S</em><em>=</em><em>9</em><em>k</em><em>m</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>now</em><em> </em><em>yo</em><em>u</em><em> </em><em>nee</em><em>d</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>time</em><em> </em><em>represented</em><em> </em><em>by</em><em> </em><em>T</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>T=D/S

T=2.16km/9km/h

so the km cancels each other

<u>you</u><u> </u><u>get</u><u> </u><u>0</u><u>.</u><u>2</u><u>4</u><u>h</u><u> </u><u> </u><u>for</u><u> </u><u>thi</u><u>s</u><u> </u><u>is</u><u>n't</u><u> </u><u>the</u><u> </u><u>solu</u><u>tion</u><u> </u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><em><u>you</u></em><em> </em><em>k</em><em>now</em><em> </em><em>th</em><em>at</em><em> </em><em>1</em><em> </em><em> </em><em>hour</em><em>=</em><em> </em><em>6</em><em>0</em><em> </em><em>minut</em><em>es</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>what</em><em> </em><em>about</em><em> </em><em>0</em><em>.</em><em>2</em><em>4</em><em>h</em><em> </em><em>you</em><em> </em><em>cr</em><em>oss</em><em> multiply</em>

<em>to</em><em> get</em><em> </em><em>1</em><em>4</em><em>.</em><em>4</em><em> </em><em>so</em><em> </em><em>you</em><em> </em><em>round</em><em> </em><em>it</em><em> </em><em>of</em><em>f</em><em> </em><em>t</em><em>o</em><em> get</em><em> </em><em>1</em><em>4</em><em> </em><em>minut</em><em>es</em>
