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.
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.
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.
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.
Answer:
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:
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:
Therefore, the inequality can be used to find the number of days, d, it will take Katie to collect over 100 seashells.
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.
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.
