Can someone please help me with this, marking brainliest and giving 15 points!The distance traveled of a coin dropped from a tall building is modeled by the equation d(t) = 4.9t2 where d equals the distance traveled at time t seconds and t equals the time in seconds. What does the average rate of change of d(t) from t = 3 to t = 6 represent? (2 points)

The coin falls down with an average speed of 132.3 meters per second from 3 seconds to 6 seconds.

The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.

The coin travels an average distance of 132.3 meters from 3 seconds to 6 seconds.

The coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.

Answers

Answer 1
Answer: change in distance = 176.4 - 44.1 = 132.3
change in time = 6 - 3 = 3

The object travels 132.3 meters in 3 seconds

the speed is the ratio of the two values

speed = distance/time
speed = 132.3/3
speed = 44.1 meters per second

This is the average speed of the object from t = 3 to t = 6 seconds. This is equivalent to the slope of the straight line through the two points.

The answer is The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.`

Jack is playing a game where he flips a coin and rolls a number cube labeled 1 through 6. He listed the possible outcomes in the sample space shown below.{(H, 2), (H, 3), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5)}

(H, 1) and (T, 6)
(H, 6) and (T, 1)
(H, 2) and (T, 6)
(T, 1) and (T, 6)

Answers

Answer:  The correct option is (A) (H, 1) and (T, 6).

Step-by-step explanation: Given that Jack is playing a game where he flips a coin and rolls a number cube labeled 1 through 6.

Jack listed the possible outcomes in the sample space 'S'' as follows:

S' = {(H, 2), (H, 3), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5)}

We are given to select the correct option that contains the two elements Jack left out by mistake.

The sample space for the event of flipping a coin is {H, T}

and

the sample space for the event of rolling a number cube labeled 1 through 6 is {1, 2, 3, 4, 5, 6}.

Let, 'S' represents the actual sample space for the event.

Then, we get

S = {(H, 1), (H, 2), (H, 3), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5), (T, 6)}.

Comparing S with S', the two missing elements were (H, 1) and (T, 6).

Thus, the correct option is (A).

The answer is (H, 1) and (T, 6)

What is the set of counting number less than 10?

Answers

Counting numbers are whole integers starting from 1 and going to infinity. It doesn't include negative numbers or zero.

Therefore, the set would be:
{1, 2, 3, 4, 5, 6, 7, 8, 9}
The set of counting numbers less than 10 is:

{9, 8, 7, 6, 5, 4, 3, 2, 1}

Jessica cannot remember the correct order of the five digits in her ID number. She does remember that the ID number contains the digits 9, 0, 3, 1, 5. What is the probability that the first four digits of Jessica's ID number will all be odd numbers?

Answers

Answer:

80%

Step-by-step explanation:

Since 4 of those 5 numbers are odd, the probability that the ID's first 4 numbers being odd is 4/5 which is 80%

ray wants the larger of two aquariums.One aquarium has 20 in. by 20 in. and has a height of 18 inches.The other aquarium has a base that is 40 in. by 12in. and has a height of 12 in. Which aquarium is larger? By how much?

Answers

To find these measurements, just multiply.

20 x 20 = 400 x 18 = 7200 in.
40 x 12 = 480 x 12 = 5760 in.

So, the first aquarium is larger. 
Subtract to find the difference.

7200 - 5760 = 1440 in.


the first A. 20 x 20 x 18= 7200
the second A 40 x 12 x 12= 5670

the first is bigger by 1530
