Renate launched an object vertically from a point that is 58.9 meters above ground level with an initial velocity of 21.6 meters

per second. This situation can be represented by the equation h=−4.9t2+21.6t+58.9, where h is the height of the object in meters and t
is the time in seconds after the object is launched.

What is the maximum height of the object?

The maximum height of the object is 82.7034 from the ground

<h3>What is Velocity ?</h3>

Velocity is the measure of movement of an object with respect to time.

It is measured in m/sec

h = -4.9t²+21.6t +58.9

dh/dt = -9.8t +21.6

At maximum height ,  velocity = 0

therefore

-9.8t +21.6 = 0

9.8t = 21.6

t = 2.204 sec

h = -4.9 (2.204)²+ 21.6 * 2.204 +58.9

h = -23.803  +47.606 +58.9

h = 82.7034 from the ground

h = 23.80 from the point it is launched.

The maximum height of the object is 82.7034 from the ground

At the grocery store 1/5 of the groceries are produce. Of the produce 2/3 is vegetables. What fraction of the groceries in the g
netineya [11]
If you have 1/5 and 2/3, you need a common denominator to even do anything. So three and five both go into 15, so then you do 2 times 5, cause 3 times 5 is 15. And 1 times 3, cause 3 times 5 is 15. So you end up with 3/15 as produce, and 10/15 as vegetables. So, then you divide the fractions, 1/5 divided by 10/15, which is the same as 1/5 times 15/10. So your answer is 3/10 of the produce is vegetables.

Eduardo’s average speed on his commute to work was 55 miles per hour. On the way home, he hit traffic and only averaged 40 miles
alekssr [168]

Answer:

40(1.25-t)

Step-by-step explanation:

There are 3 components to consider; time, speed and distance

Time and Speed are given.

The distance has to be calculated.

  • Speed to work = 55 miles per hour
  • Time to work = 1.25-T
  • Speed to home = 40 miles per hour
  • Time to home = 1.25-t
  • Total Time = T + t = 1.25

<u>Distance for trip to home</u>

Speed = Distance/Time

40 = Total Distance/1.25-t

Total Distance = 40(1.25-t)

<em>Therefore, 40(1.25-t) is the correct answer.</em>

!!
