Answer:
24 ft
Step-by-step explanation:
Let x represent the height of the tree. The geometry can be represented by a right triangle with a base of 70 ft, a height of x ft, and a hypotenuse of 2+3x ft. The Pythagorean theorem tells us the relationship ...
x^2 +70^2 = (2+3x)^2
8x^2 +12x -4896 = 0 . . . .put in standard form
2x^2 +3x -1224 = 0 . . . . remove a common factor of 4
(2x +51)(x -24) = 0 . . . . . factor
The only positive solution is x = 24.
The height of the tree is 24 feet.

<u>Option: a</u> is correct.
Limit of the function at x=2 is: 2
Step-by-step explanation:
Clearly by looking at the graph of the function we could observe that the function f(x) is defined as:
f(x)= -x+4 when x≠4
and 8 when x=2
since we could see that the function f(x) is a line segment that passes through the point (4,0) and (0,4).
and the equation of line passing through two points (a,b) and (c,d) is given by:
Here a,b)=(4,0) and (c,d)=(0,4)
Hence,
the equation of line is:
Now the left hand limit of the function at x=2 is:
Similarly the right hand limit of the function at x=2 is:
Hence, the limit of the function at x=2 is:
2
