suppose you lean out a window of a tall building and use a sling to launch a stone straight up. the stone starts with a velocity of 69 feet per second. it leaves the sling 365 feet above the ground.
Answers
Answer:
y= 69x + 356
Step-by-step explanation:
y= 69x + 356
It goes 69 feet per second hence the 69x and it starts 356 feet in the air
The height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t^2 + 69t + 365.
How to write a function?Assuming that the acceleration due to gravity is -32 feet per second squared (neglecting air resistance), we can use the following kinematic equation to describe the height of the stone as a function of time:
h(t) = -16t²+ vt + h₀
where:
h(t) is the height of the stone above the ground at time t
v is the initial velocity of the stone (69 feet per second, in this case)
h₀ is the initial height of the stone (365 feet above the ground, in this case)
Substituting the values of v and h0, we get:
h(t) = -16t² + 69t + 365
Therefore, the height of the stone above the ground at any time t can be described by the quadratic function h(t) = -16t² + 69t + 365.

In three to five sentences, explain the importance of sentence structures in good writing.
Answers
Answer:
Sentence structure needs to simple, standalone, Grammarly justified and able enough to convey the writer thoughts and feelings clearly
Step-by-step explanation:
Sentence structure is very essential to convey the idea of the writer clearly. It is just like the skeleton of a write up and hence its framework needs to be clear and able enough to express the real sense. The structure of sentence needs to be complete with adequate grammar and punctuations. A good sentence must be able to express a complete idea on its own.

Two random samples were taken to determine how often people in a community listen to the local radio station each month.
The first sample surveyed 15 people as they exited the bank on Main Street. The first sample found that the mean number of hours they listened to the radio each month was 20.
The second sample surveyed every sixth person as they exited the only local grocery store until 100 people were surveyed. The second sample found that the mean number of hours they listened to the radio each month was 12.
Which statements are true? Check all that apply.
The second sample is random.
The second sample is likely to be more representative of the population.
The first sample is likely to be more representative of the population.
The second sample will give a better representation because is it larger.
The first sample will give a better representation because it is smaller.
Community members are more likely to listen to the radio station an average of 12 hours a month than 20 hours a month.

Volume of a triangular pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
1). Volume of the pyramid = [tex]\frac{1}{3}(72)(15)[/tex]
= 360 cm³
2). Volume of the pyramid = [tex]\frac{1}{3}(\text{Area of the triangular base})(\text{Height})[/tex]
Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]
= [tex]\frac{1}{2}(8)(5)[/tex]
= 20 cm²
Therefore, volume of the pyramid = [tex]\frac{1}{3}(20)(12)[/tex]
= 80 cm³
5). Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]
Here, r = radius of the circular base
h = Height of the cone
Volume of the cone = [tex]\frac{1}{3}\pi (2)^2(4)[/tex]

The length of a rectangle is four times the width minus three. If the perimeter of the rectangle is 64 meters, what is the length?
Answers
Answer:
L = 25 m
Step-by-step explanation:
L = 4W - 3
perimeter = 2(L + W)
64 = 2(4W - 3 + W)
divide both sides by 2:
32 = 5W - 3
add 3 to each side:
5W = 35
divide both sides by 5:
W =7
L = 4(7) - 3 = 25

In a kindergarden class of 19 students, 100 addition problems can be completed in a mean time of 6 minutes. The
standard deviation is 1 minute.
How many students will finish before 5 minutes?
Answers
Answer:
3 students
Step-by-step explanation:
Two ways you can do this:
1. If you have a graphic calculator you can find the normal distribution function and enter the following values to get the probability of a student finished in less than 5 minutes:
Lower: 0
Upper: 5
Standard Deviation: 1
Mean: 6
This gives a probability of: 0.1587 (4.d.p)
2. You can use the formula and find the probability using the Z-table.
[tex]Z = \frac{x - \mu}{\sigma}[/tex]
Substitute known values:
[tex]Z = \frac{5 - 6}{1}\\Z = -1/1 = -1\\[/tex]
It is one standard deviation to the left of the mean,.
Look up on Z-score table and we get: 0.1587 (4.d.p)
Now we need to find expected number. We do this by multiplying the probability by the amount of people:
0.1587 x x19 = 3.0153 rounded to 3 students.

The given triangle is congruent to the second triangle because they same construction methods and the have same size and same shape.
What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
We have given a congruent triangle in the picture.
After close observation, the second triangle has the same size and the same shape, and the same construction method by arc method.
Other triangles have different construction methods.
Thus, the given triangle is congruent to the second triangle because they same construction methods and the have same size and same shape.
