If you were to add it, it would be 3x^3-x^2+1 same answer if you wanted to simplify or write in standard form!
Points A and C are the endpoints of one diagonal. Its slope will be
.. (5-(-1))/(-1-(-5)) = 6/4 = 3/2
Points B and D are the endpoints of the other diagonal. Its slope will be
.. (-2-6)/(3-(-9)) = -8/12 = -2/3
The diagonals cross at right angles, so the figure is a rhombus or a kite.
The midpoints of the diagonals are
.. (A +C)/2 = (-5-1, -1+5)/2 = (-3, 2)
.. (B +D)/2 = (-9+3, 6-2)/2 = (-3, 2)
The midpoints of the diagonals are the same. The diagonals are perpendicular bisectors of each other, so the figure is a rhombus.
Answer:
16p + 6
Step-by-step explanation:
(12p + 9) + (4p - 3)
12p + 4p = 16p
9 + (-3) = 6
Answer: 16p + 6
I’m assuming this is -x^2 = 15
standard form: -x^2 - 15 = 0
Answer:
-
Step-by-step explanation:
using the half angle formula
cos( ) = ±
cos195° = cos(180 + 15)° = - cos15°
then
cos15° = cos ( ) = = = =
then
cos195° = - cos15° = -
