For this case we have the following expression:
By definition, a constant term is a value that cannot be modified, does not vary.
It is observed that the first three terms of the expression depend on a variable, therefore they are not constant.
The fourth term "3" is the constant term of the expression.
Answer:
The constant term is 3
<h3>Answer: 35.4</h3>
====================================================
Explanation:
Let x be the reference angle where the question mark is located.
Opposite this angle x is 27. The adjacent side is 38.
Use the tangent ratio to tie the two sides together
tan(angle) = opposite/adjacent
tan(x) = 27/38
x = arctan(27/38)
x = 35.3947958 .... which is approximate
x = 35.4
Be sure that your calculator is in degree mode. The notation "arctan" refers to "arctangent" which is the same as inverse tangent. Your calculator should have a button labeled to help compute this.
Considering the directrix and vertex given in the graph, the equation of the parabola is:
B.
The equation of a quadratic function, of vertex (h,k), is given by:
(y - k)² = 4p(x - h).
In which the directrix is the line x = h - p.
Looking at the graph, we have that:
- The vertex is (-2,-2), hence h = k = -2.
- The directrix is x = -1, hence -1 = -2 - p -> p = -1.
Thus the equation is:
(y + 2)² = -4(x + 2).
Writing x as a function of y:
B.
