Answer:
y=-0.012x(x-200).
Step-by-step explanation:
1) the given parabola has two zeros: 0 and 200. It means, the required equation is: y=ax(x-200), where a - unknown number;
2) according to the given graph the vertex is (100; 120). It is possible to substitute the coordinates of it into the equation y=ax(x-200) and calculate the value of 'a':
120=a*100(100-200); ⇒ a=-0.012.
3) finally, the required equation is:
The measure of the cscθ and secθ are 5/4 and 5/3 respectively option (A) is correct.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a standard-position angle determined by the point (x, y).
The point is (9, 12)
From the Pythagoras theorem, we can find the hypotenuse(h):
h = √(9²+12²)
h = 15
cscθ = hypotenuse/opposite = 15/12 = 5/4
secθ = hypotenuse/adjacent = 15/9 = 5/3
Thus, the measure of the cscθ and secθ are 5/4 and 5/3 respectively option (A) is correct.

The answers b. |3.7| = 3.7 so the answer will be 3.7
C. The object of the sentence.
First, let's identify the common noun:
Mary - wrong, cause it's a name.
Frog - yes, it's a common noun.
Second, let's see its role in the sentence:
It comes after a verb, showing that it must be either an object of a predicate.
Predicate - wrong, cause "caught" is not a linking verb.
Object - correct answer.
---> Final answer: C.
