Americans consume about 13,150,000,000 gallons of carbonated drinks each year. express this number in scientific notation. a) .1315 x 1011 b) 1.315 x 1010 c) 1.315 x 1011 d) 13.15 x 109
answer is b

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
