Which statement BEST describes the attributes of the graph of the function y = x 2 − 8 x − 20 ? A. The function has zeros at (10, 0), and (–2, 0), and has a vertex at (4, –36). B. The function has zeros at (–10, 0), and (–2, 0), and has a vertex at ( –4, –36). C. The function has zeros at (10, 0), and (–2, 0), and has a vertex at (–4, –36). D. The function has zeros at (–10, 0), and (2, 0), and has a vertex at (4, –36).

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

is only a line? i think so

its an acute right triangle

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
