Answer:
False.
Rather, the velocity component at any point is equal to the ****slope**** of the tangent line of the position-time graph at that point.
Step-by-step explanation:
Mathematically, velocity at any point, v= dx/dt at that point; which is the instantaneous slope of the tangent of the position-time graph at that point.
Answer:
TQ=SR [since it is isosceles trapezoid]
6x+1.2=9x-48
48+1.2=9x-6x
3x=49.2
x=49.2/3=16.4
now
QR=3×16.4+2.5=51.7
SR=9×16.4-48=99.6
ST=4×16.4-2=63.6
TQ=6×16.4+1.2=99.6
Answer:
If 21 is the height, and 4 is the radius, then the volume is approx. 1055.58
Step-by-step explanation:
You have to write two equation:
'substract 22 from a number'

and:
'the result is doubled, the answer is 6 more than the original number'

then you change 'Y' in 2nd equation for left side of 1st equation:

count it and you get:

This means that X=50
The original number is 50.
