For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
According to the data of the statement we have two points through which the line passes:
We found the slope:
Thus, the equation is of the form:
We substitute one of the points and find "b":
Finally, the equation is:
Answer:
Answer:
x = 19.06 feet
Step-by-step explanation:
Given that,
The length of a tree, h = 16 feet
It casts a shadow which forms an angle of 40° with the ground.
We need to find the length of the shadow. We can find it using trigonometry such that x be the length of the shadow. So,
So, the length of the shadow is 19.06 feet.

Recursive formula= a(n)=a(1)(n-1)+d
a(n)= 9(n-1)+2
explicit formula= a(n)= a(1)+(n-1)d
a(n)= 9+(n-1)2
12th row= a(12)=9+(12-1)2
a(12)=9+11(2)
a(12)=9+22
a(12)=31
