The graph of a quadratic equation is a U-shaped curved called parabola. It is because the parabola makes very easy to find the axis of symmetry to plot selected points and finding the roots and vertex.
Good luck :)
Yes it is a function!, all the first numbers are none repeating, for example it says -5,4,6 since they are not the same this is a function
Answer:
Step-by-step explanation:
For angle C,
cos(∠C) =
= 0.97
sin(∠C) =
= 0.26
tan(∠C) =
= 0.27
Therefore, from the triangle ABC,
cos(∠A) = cos(90° - ∠C)
= sin(∠C)
= 0.26
sin(∠A) = sin(90 - ∠A)
= cos(∠A)
= 0.97
tan(∠A) =
= 3.73
Angle

A 0.26 0.97 3.73
the answer i got was 18.12
