Asanji stands at the edge of the top of a tall building and lobs a watermelon up into the air then proceeds to watch it fall to the street below (luckily it's empty because everybody is at home). The equation below represents the height, off the ground in meters, of the watermelon t seconds after Asanji has thrown it.
h = -4.9t^2 + 9.8t + 28
Approximately, how long does it take the watermelon to hit the ground? Round to the nearest tenth of a second.

Answer:
3.6 s
Step-by-step explanation:
This is nicely solved by a graphing calculator. It takes about 3.6 seconds to hit the ground.
__
We notice that the vertical velocity is a multiple of the leading coefficient, so we can solve this by completing the square.
0 = -4.9(t^2 -2t) +28 . . . . . for h = 0
28 +4.9 = 4.9(t^2 -2t +1) . . . . . rearrange, add 4.9 to both sides
32.9/4.9 = (t -1)^2
1 +(1/7)√329 = t ≈ 3.5912. . . . . square root and add 1
It takes about 3.6 seconds for the watermelon to hit the street.

The m’s would all be the same number.Another way of adding the same number to each other would be to multiply that number by the number of times you want to add it to each other.
With m + m + m you are adding it 3 times.

What is a sequence?A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.
Consider the given figure, which shows groups of dots arranged in increasingly larger hexagons.
If the pattern continues, the next group of dots would have 61 dots.
The first difference will be
The difference between 7 and 1 is 6.
The difference between 19 and 7 is 12.
The difference between 37 and 19 is 18.
The difference between 61 and 37 is 24.
The second difference will be
The difference between 12 and 6 is 6.
The difference between 18 and 12 is 6.
The difference between 24 and 18 is 6.
Thus, the sequence is arithmetic, because the second differences are constant. Then the correct option is B.

Jane had $d to buy three Beanie Babies. (In our problem, they all cost the same).
If she were to buy all three, she’d spend all her money. Instead, she bought just one.
How much money does Jane have left after buying the Beanie Baby? Brainliest to correct answer:)
Answers
Answer:
$2/3d
Step-by-step explanation:
since it says that if she were to buy all three beanie babies, she'd spend all of her money, this means that since she bought 1, she only used up 1/3 of her money, or $1/3d.
so, after buying the beanie baby, she has $2/3d left.

The number of items sold over a four-month period are: month 1 2 3 4 sales 5100 5500 5400 5600 Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method with weights of 0.6 for the most recent month and 0.3 for the next to the most recent month. Further, suppose that the exponential smoothing constant α=0.5. Then calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method. Under the 3-month weighted moving average method, what is the forecast for the fourth month?
Answers
Answer:
By using 3-month weighted moving average method -
Forecasts for the 4th month = 5400
Forecasts for the 5th month = 5530
By using Exponential smoothing method -
Forecasts for 3rd month = 5300
Forecast for 4th month = 5350
Forecast for 5th month = 5475
Step-by-step explanation:
To find - Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method.
Calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method.
Proof -
Given that,
month 1 2 3 4
sales 5100 5500 5400 5600
F(4) = 0.6 A(3) + 0.3 A(2) + 0.1 A(1)
= 0.6 [ 5400] + 0.3 [ 5500] + 0.1 [ 5100]
= 3240 + 1650 + 510
= 5400
⇒forecasts for the 4th month = 5400
Now,
F(5) = 0.6 A(4) + 0.3 A(3) + 0.1 A(2)
= 0.6 [ 5600] + 0.3 [ 5400] + 0.1 [ 5500]
= 3360 + 1620 + 550
= 5530
⇒forecasts for the 5th month = 5530
Now,
Given that, the exponential smoothing constant α=0.5
Month Sales Forecast
1 5100 5100
2 5500 5100 + 0.5(5100 - 5100) = 5100
3 5400 5100 + 0.5(5500 - 5100) = 5300
4 5600 5300 + 0.5(5400 - 5300) = 5350
5 5350 + 0.5(5600 - 5350) = 5475
∴ we get
By using Exponential smoothing method -
Forecasts for 3rd month = 5300
Forecast for 4th month = 5350
Forecast for 5th month = 5475

Answer:
The correct answer is m∠2 = 120°
Step-by-step explanation:
There is a triangle rule that states the outer angle of an angle in a triangle is equal to the sum of the remaining two angles in that triangle, which means that m∠2 = 52° + 68° = 120°. This can be proven correct because the sum of two of the angles in the triangle is 120°, which means the final angle is 60°. Since m∠2 is the outer angle of 60°, that means it will be 180° - 60° or 120°.

The Environmental Protection Agency (EPA) publishes fuel economy values that are known to be good estimates of the fuel economy a typical driver will achieve under average driving conditions. One of the fuel economy values the EPA publishes is a combined estimate, which represents a combination of city driving (55%) and highway driving (45%). A large car rental company has 16 Ford Explorers in their fleet. They collected fuel economy data from these cars and calculated the sample mean to be 23.29 mpg and sample standard deviation as 0.78 mpg.
Required:
The car rental company is willing to assume that the conditions are met for constructing a confidence interval. Use the collected data to construct a 90% confidence interval for the mean combined fuel economy for Ford Explorers.
Answers
Answer:
The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 16 - 1 = 15
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.7531
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.7531\frac{0.78}{\sqrt{16}} = 0.34[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 23.29 - 0.34 = 22.95 mpg
The upper end of the interval is the sample mean added to M. So it is 23.29 + 0.34 = 23.63 mpg
The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.
