Answer:
61.97 feets
Step-by-step explanation:
Using trigonometry :
Horizontal distance between the person and building,
Let distance = d
Tan 15 = 15 / d
0.2679491 * d = 15
d = 15 / 0.2679491
d = 55.980781
To obtain the height, h :
tan 40 = (h-15)/d
d = 55.98
h-15 = 55.98 (tan 40°)
h - 15 = 55.98 * 0.8390996
h - 15 = 46.972797
h = 46.972797 + 15
h = 61.972797
h = 61.97 feets
The given question have mistake. The correct question is written below.
Question:
A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?
Answer:
Option B:

Solution:
<u>General formula for the height of the projectile over time:</u>
(1) 
Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)
(2) 
Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)
Given initial velocity = 6.37 s and initial height is 0.
The height of the dog is in meters.
So, use second formula and substitute v = 6.37 and s = 0.



Hence option B is the correct answer.
The first thing we must know in this case is that the distance is equal to the speed for time.
We have then:
For Chris:
d1 = 40 * t
For Amy:
d2 = 60 * (t-2)
The distance between both will be given by the hypotenuse of the rectangle triangle:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
Answer:
300 = root ((40 * t) ^ 2 + (60 * (t-2)) ^ 2)
option 3
Answer:The shape of the distribution refers to the graph of the data. The data can be graphed using a histogram, which is like a bar graph. If the height of all the bars is the same, the shape is called uniform, and the data is distributed evenly across the range.
