Step-by-step explanation:
If 1990 is x = 0, then 1997 is x = 7.

Answers:
- A) Definition of right angles
- B) Substitution
- C) Definition of congruence
=========================================
Explanation:
- A) The term "right angle" is another way of saying "90 degree angle". This is a definition. Think of a definition in a dictionary.
- B) The substitution property allows us to replace one thing for another, as long as the two things are equal. The transitive property works as a similar idea.
- C) If two angles have the same measure, then they are congruent. This is the definition of congruence (or one form of it).
Answer:
Step-by-step explanation:
This is our quadratic:

where s(t) is the position of the object after all the stuff on the right side happens to it. If the object lands on the ground after all that stuff happens to it, its height is 0. Subbing in a 0 for s(t) gives us:

and if the object hits the ground at 21 seconds, we can sub in a 21 for each t to get this:
and do the math.
and solving for the height:
h = 1845.9 meters
The answer to question 10 would be B. 22 square feet and i'm guessing the answer to question 11 would be A. A triangular prism.<span />
