Answers
Answer:
D.)
Explanation:
[tex]A=[/tex]πr²
[tex]A=[/tex]π[tex](4x^{7} y^{3} )^{2}[/tex]
According to the Power Rule you raise coefficients to the power and multiply the exponents
[tex]A=([/tex]π[tex])(16x^{14} y^{6} )[/tex]
[tex]A=16[/tex]π[tex]x^{14}y^{6}[/tex]

f(g(x))
f(2x) = (2x)^2 - 8
= 4x^2 - 8

How much charge is needed to repel another charge of 9.9 x 10^-6 N when they are 200m apart? Please help meee I really can't understand Coulomb's Law : (
Answers
Answer:
The charge needed will be [tex]q=6.6\: \mu C[/tex]
Step-by-step explanation:
The equation of the electric force is given by:
[tex]F=k\frac{qQ}{r^{2}}[/tex]
We have the force [tex]F = 9.9 10^{-6}\: N[/tex] and the distance r = 200. k is the Coulomb constant. Q and q are the charges.
We assume we have the same charge of the particles, so we have:
[tex]q^{2}=\frac{Fr^{2}}{k}[/tex]
[tex]q^{2}=\frac{9.9*10^{-6}200^{2}}{9*10^{9}}[/tex]
[tex]q=6.6*10^{-6}\: C[/tex]
Therefore, the charge needed will be [tex]q=6.6\: \mu C[/tex]

In continuous type of series, for finding mean, which amongst the
following is considered as X variable value?
Select one:
O a lower limit of the interval
O b. upper limit of the interval
O c. mid point of the interval
O d. none of these
Answers
In the continuous type of series for determining the mean, the midpoint of the interval should be considered as the X variable value.
Continuous Series is the series where all types of class intervals with the frequency should be listed in the table form. Here all the class intervals do not contain a similar frequency.
For determining the mean, the direct method should be used in which the midpoint from X should be measured and the same should be relevant.
So, the following should not be relevant for determining the mean:
The lower limit and upper limit of the interval.Therefore In the continuous type of series for determining the mean, the midpoint of the interval should be considered as X variable value.
