A person springs off a 12-foot high diving board with an initial velocity of 10 feet per second. How many seconds does it take the person to hit the water?

Answers

Answer 1
Answer:

Answer:

1.2 seconds

Step-by-step explanation:

The height of the diving board above water is 12 feet.

The person dives with an initial velocity of 10 feet per second.

The time taken is gotten by dividing the height jumped by the velocity at which the person dived.

That is:

t = d / s

where d = height jumped = 12 ft

s = velocity = 10 ft/s

Therefore:

t = 12 / 10 = 1.2 seconds

It took the person 1.2 seconds to hit the water.

Given the linear equation 2x + y = 6, perform the necessary operations to put the equation into the proper general form. Explain in complete sentences how you knew that the equation was in the proper general form. Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Include the entire process for establishing the general form of the equation and the general form.

Answers

Step-by-step explanation:

The general equation is y = mx + c...

The given equation is 2x + y = 6

Firstly, move everything on the left except the y to the right.i.e.

y = 6 - 2x

Secondly, rearrange the values on the right to look just like the general equation.

y = -2x + 6

The equation is now in proper general form because it matches the format laid down.

The population of the country of Oz was 600,000 in the year 2010. The population is expected to grow by a factorof 5% annually. The annual food supply of Oz is currently sufficient for a population of 700,000 people and is
increasing at a rate that will supply food for an additional 10,000 people per year.
c. At what point does the population exceed the food supply? Justify your response.

Answers

Answer:

After 5 years (2015)

Step-by-step explanation:

The population is increasing 5% per year, so the first year it will be 1.05 of the initial, the next year 1.05x1.05 of the initial, and then  successively, so, for n years:

P(n) = 600,000*(1.05)ⁿ

The food suply increase 10,000 people per year, so the first year will be 10,000 + the initial, the next year 10,000 + 10,000 + the initial, and then  successively, so, for n years:

F(n) = 70,000 + 10,000*n

So

P(n) > F(n)

600,000*(1.05)ⁿ > 70,000 + 10,000*n

(1.05)ⁿ > 1.167 + 0.0167n

Solving in a computer:

n > 4.42

So, after 5 years the population exceed the food supply.

Katie wants to collect over 100 seashells. She already has 34 seashells in her collection. Each day, she finds 12 more seashells on beach. Katie can use fractions of days to find seashells. Write an inequality to determine the number of days, dd, it will take Katie to collect over 100 seashells

Answers

Answer:

12d+34>100  

Step-by-step explanation:

Let d be the number of days.

We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.  

We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be: 12d+34

As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100. We can represent this information in an inequality as:

12d+34>100

Therefore, the inequality 12d+34>100 can be used to find the number of days, d, it will take Katie to collect over 100 seashells.

Final answer:

In order to find out when Katie will have over 100 seashells, we use the equation 34 + 12d > 100. After simplifying, the inequality is d > 5.5. So, it will take Katie over 5.5 days to collect over 100 shells.

Explanation:

The question states that Katie already has 34 seashells and finds 12 more each day. This can be represented by the equation 34 + 12d, where d represents the number of days. In order to find out when Katie will have more than 100 seashells, we need to set this equation greater than 100 and solve for d.

So, 34 + 12d > 100. If we subtract 34 from both sides, we get 12d > 66. Then, divide both sides by 12 to solve for d. d > 66/12. The value of d in this case turns out to be approximately 5.5.

This means it will take Katie slightly over 5.5 days to collect over 100 seashells, given that she can use fractions of days to find seashells.

Emmett squeezed 1/3 cup of orange juice in 2 minutes. He divided to find how many cups of orange juice he could squeeze per minute, but he made a mistake. Which reason explains why his answer must be wrong?

Answers

Given:
1/3 cup of orange juice in 2 minutes

Unit rate is needed.

1/3 ÷ 2 

Steps in dividing fractions.
1) Get the reciprocal of the 2nd fraction.
     2 is the 2nd fraction. It is 2/1 in fraction form. Its reciprocal is 1/2
2) Multiply the 1st fraction to the reciprocal of the 2nd fraction

1/3 * 1/2 = 1*1 / 3*2 = 1/6 cup

Emmet can squeeze 1/6 cup of orange juice per minute.
