Is there no answer choices.
Assuming that this happened at the same environment like the time of day, then we can use ratio and proportion. We relate the height of the tree with its shadow by using the ratio of the biologist's height to his shadow.
Height of tree/Height of its Shadow = Height of biologist/Height of his Shadow
Height of tree/28 = 7/2
Height of tree = 7*28/2
Height of tree = 98 feet
The answer is D.

Step-by-step explanation:
<u>Standard Form of Quadratic Function</u>
The standard representation of a quadratic function is:

where a,b, and c are constants.
Solving with the quadratic formula:

We have the following equation to solve:

Rearranging all the terms to the left side:

Comparing with the general form of the quadratic equation: a=6, b=-5, c=-3. Apply the formula:



Correct Choice: Second Option
No trend or linear association
Answer:
2. 19.47 in
3. 153.86 square centimeters
Step-by-step explanation:
2. The circumference of a circle is π times the diameter, so in this case it is 6.2 * 3.14 = 19.47 in (rounding to nearest hunderdth).
3. The area of a circle is π/4 times the diameter squared, so in this case it is 14^2 * 3.14 / 4 = 153.86 square centimeters.
