The answer is 6. Sorry, I don't know why though.
The height of the tree given the depression angle to the top and the base
is given by the tangent relationship of the two given angles.
Correct response:
- The height of the tree is approximately <u>79.58 feet</u>
<h3 /><h3>Methods used for the calculation of the height of the tree</h3>
Given:
Altitude of the hot air balloon = 800 feet
Angle of depression to top of tree = 43°
Angle of depression to base of tree = 46°
Required:
Height of tree
Solution:
The horizontal distance of the balloon from the tree is given as follows;
Therefore;

Therefore;

- Height of tree = Altitude of balloon - Height of balloon above tree
Therefore;

4 (x + yi) +5 (x + yi)
(4x + 4yi) + (5x + 5yi)
4x _5x +4yi _5yi
_1x + _1yi
therefore x= _1
Answer:
a. A quadratic can only have one y-intercept.
Step-by-step explanation:
If the function is
and f(4) − f(1) = f '(c)(4 − 1) then there is not any answer.
Given function is
and f(4) − f(1) = f '(c)(4 − 1).
In this question we have to apply the mean value theorem, which says that given a secant line between points A and B, there is at least a point C that belongs to the curve and the derivative of that curve exists.
We begin by calculating f(2) and f(5):
f(2)=
f(2)=1
f(5)=
f(5)=1
And the slope of the function:
(x)=
(c)=0
Now,

=-2
=0
-2 is not equal to 0. So there is not any answer.
Hence if the function is
and f(4) − f(1) = f '(c)(4 − 1) then there is not any answer.
