Answer:
yes because hiiibvf fdryyy hhhhhhh hhhhb hhhh
Step-by-step explanation:
it is the vertex form.
remember, (h, k) is the vertex point.
the vertex being the point of the (quadratic) parabola, where the curve turns around.
depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.
so, the first a. is correct.
and so is the second a., as they play an important role when completing the square and hence finishing the transformation.
Answer:
C
Step-by-step explanation:
The area (A) of the triangle is calculated using
A = 
ab sinC
where a, b are the 2 sides and C is the angle between them
here a = 9, b = 15 and C = 70°, hence
A = 0.5 × 9 × 15 × sin70° = 63.4 cm² → C
Answer:
0
Step-by-step explanation:
If you think in degrees easier than in radians, then make this conversion.
pi = 180 degrees
(3/2)*pi = (3/2) * 180 = 180 * 3/2 = 270
Sin(270) = -1
cos(270) = 0
==========
sin(270) * cos(270) = -1 * 0 = 0
