5 * 6 + 4 * 6 + 3 * 6 + 2 * 1/3 * 3 * 4
4/3* pi *5.6^3 = 735.6185806037668392
Coulomb's Law F= k q1 q2 / d^2 k=Coulomb's constant = 9.0 x 109 N m2 /C2
q1 =-2 x 10-5 q2 = 4 x 10-6 C d = .004 m Plug in these numbers to get the force exerted in Newtons
55 = -16t^2 + 32t + 48
-16t^2 + 32t - 7 = 0 Now use Quadratic Formula to solve for the t's whenthe height = 55 ,
the smaller t will be on the way UP and the larger will be on the way back down
m + 1/m = 8 find common denominator ..... multiply first term by m/m
m * m/m + 1/m = 8 add numerators
(m^2 +1)/m = 8
(2 x 108 ) 2 = 4 x 1016
Yes.
Median is the middle number in the list when listed in ascending order ..... if there are TWO numbers in the middle...it is the average of those two.
Vertex form of parabola
y = a (x- -2)^2 -3
= a ( x+2)^2 -3 sub in the point given to calculate 'a'
-2 = a (-5+2)^2 - 3
a = 1/9
y = 1/9 (x+2)^2 -3 <======== expand this to find your answer ( well....you really should be able to see the answer without expanding)
Point 7,4 slope = 3/2
(y-4) = 3/2 ( x-7)
