Answer:
x intercept: 5
y intercept: 50
Step-by-step explanation:
- let us plot the graph for better understanding.
- we will represent f(x) on y-axis so, the equation will become: y= 50-10x
- the equation is of the form : y=mx+c
[where, m: slope of the line
c : y-intercept ]
- meaning of x intercept: the x-coordinate of the point where the line meets x-axis
- meaning of y intercept: the y-coordinate of the point where the line meets y-axis
- the line y= 50-10x has slope of -10 and it passes through (0,50)
[ (0,50) lies on the line only. substitute and check if the point satisfies the above line equation]
- by seeing the graph in the attachment and by the definitions given above, we can say that,
x intercept: 5
y intercept: 50

Answer:
Hence the ground distance is about 889m between stadium and Tennis court.
Step-by-step explanation:
Given:
A pilot at height of 125 m(flying the advertising blimp)
angle of depression=8 degrees.
To find :
The ground distance stadium and tennis court.
Solution :
Using Trigonometric Function we can solve it ,
(Refer the attachment for fig)
Considering above data we get a triangle(ABC)
with point A represent pilot position and C court position and B as stadium.
The height AB=125 m
angle of depression= 8 degrees.
Using
<em>tan∅ =AB/BC</em>
tan(8)=125/BC
BC=125/tan(8)
=125/0.14054
=889.2
=889 m
Hence the ground distance is about 889m between stadium and Tennis court.
