14 = 9/5 C +32 subtract 32 frm both sides
-18 = 9/5 C
-18 (5/9) = c = -10 C
Conservation of momentum
m1 v1 = m2 v2
5 *3 + 3 *2 = (5+3) v2
21/8 = v2 = 2.625 m/s
Kinetic energy = 1/2 mv^2 initially = 1/2 5000 (3^2) + 1/2 3000 (2^2 ) = 2,8500 kg m^/s^2
after = 1/2 8000 2.625^2 =27,562.5 Difference = 937.5 kg - m^2/s^2
Rate x time = distance time = 5.25/60 of an hour
200 m/hr x 5.25/60 hr = ?
The graph shows it correctly BUT the base is 6.5 (not 6.25)....did YOU even look at the graph provided and understand the solution???
6.5 x 2.6 x 1/2 = 8.45 units2
Slope intercept form is y = mx + b if you got 1/7 for slope you would write it as 1/7 x + b
First , bust it up into its real and imaginary components:
2i=yi-3xi and x = y since x = y, sub this into the first equation
2i =xi-3xi
2i = -2xi
x = -1 so since x=y y = -1
put in your number (I assume it is a decimal) and hit the = button....then look above the calculator display.....
Oh...I see now...ths is ONE question with four choices....the answer is the first graph....the one on the left of the first screenshot....
Well...are you just guessing?
I cannot tell which one it is because there is no eqaution visible to me when I open your screenshot....it got cut off !
The first one is the one on the left ....what do you think the second one's answer is?
