Answer:
x would be = to 13
Step-by-step explanation:
The force F newtons between two magnetic poles is given by the formula
F = \displaystyle\frac{1}{500r^{2}} where r m is their distance apart.
Find the rate of change of the force when the poles are 0.2 m apart and the distance between them is increasing at a rate of 0.03 ms^-1"
\displaystyle\frac{dF}{dt} = \frac{dr}{dt}*\frac{dF}{dr}
dr/dt = 0.03 ms^-1 and df/dr = -1000r^-3.....where r = 0.2m so don't i just do for df/dr, -1000*(0.2^-3) and then multiply it by 0.03???
Answer:13
Step-by-step explanation:
36-23=13
Absolute value which means even negative integers are considered as positive
Answer:
C, 38°
Step-by-step explanation:
ray UW is the angle bisector of ∠VUT
--> m∠VUW = m∠WUT = 1/2 m∠VUT
<=> 4x + 6 = 6x - 10
<=> 6 + 10 = 6x - 4x
<=> 2x = 16
<=> x = 8
So, the measure of m∠WUT is: 6x - 10 = 6 . 8 - 10 = 48 - 10 = 38°
