Janice measured the mass and the volume of an object. She then determined the density of the object by dividing the object’s mas
meriva

Answer:

The answer is letter D (last choice) 6g/cm^3

Explanation:

Just did it!

If you have the mass and the volume...what is left is the density. Density uses grams per cubic centimeter. Plus, the number can't be negative so the last answer will be the positive number with the correct measurements.

Hope this helps.

Please give branliest.

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.
