Answer:
10.77
Step-by-step explanation:
by using Pythagoras theorem we can find the distance between the points,
so...
distance between the points, which is the hypotenuse will be xy
difference between the y coordinates will be dy
difference between the x coordinates will be dx
according to pythagoras theorem,
For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a
f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1
the axis of symmetry is x=-1
B
Answer:
0.3 kg
Step-by-step explanation:
I hope it helps, have a good day
Two faces are 3*5 = 15; and because there are two faces you double to get 30;
5*8 = 40, double to get 80,
3*8 = 24, double to get 48, and we add:
48 + 30 + 80 = 158
