Answer:
050°
Step-by-step explanation:
The bearing of D from C is the angle between the north pole and the line joining C and D when moving in a clockwise direction.
From the diagram, the angle is 050°
Answer:
you are correct :)
Step-by-step explanation:
complementary angels equal 90 degrees so you do 90-52
supplementary angels on the other hand, equal 180 degrees
Answer:
answer is -9
Step-by-step explanation:
5(x+1)=4(x-1)x
5x+5=4x-4+x
5x+5=4x+x-4
5x+5=5x-4
5x-5x=-4-5
x=-9
We have points (-1,3),(0,1),(1,3) so we can set up a system of equations for the general form ax^2+bx+c...
a+b+c=3, 0a+0b+c=1, a-b+c=3 getting differences
a+b=2, -a+b=-2 getting the sum
2b=0, b=0, making a+b=2 become:
a+0=2, a=2, making a+b+c=3 become:
2+0+c=3, c=1 so
y=2x^2+1
