Answer:
is there a figure for this question?
Answer:
<h2>1. (-6, 0) and (-1, 0)</h2><h2>2. not exist</h2><h2>3. (5, 0)</h2>
Step-by-step explanation:
The zeros of a quadratic function are x-intercepts of parabola.
Graph #1:
x = -6 and x = -1
Graph #2:
not exist
Graph #3:
x = 5
Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
Rewriting the formula in standard form would be x^2-8x+14=0
Answer:
-8a times 1/9
Step-by-step explanation:
This can be thought of as -8a/1 times 1/9. (1/9 is the reciprocal of 9, so were just pulling the fraction apart)
