Answer:
(f o g)(x) = 4x^2 - 8
Step-by-step explanation:
(f o g)(x) = f(g(x))
f(x) = x^2 - 8
g(x) = 2x
f(g(x))
f(2x) = (2x)^2 - 8
= 4x^2 - 8
(f o g)(x) = 4x^2 - 8
Find: m∠1, m∠2, and m∠5 in degrees
Answers
Answer:
<1 = 100
<2 = 80
Step-by-step explanation:
Angle 1 and angle 2 are supplementary
Supplementary angles add to 180 degrees
<1 + <2 = 180
The angles are in a ratio of 5 to 4
Multiply by x to get the measure of each angle
<1 = 5x <2 = 4x
5x+4x = 180
Combine like terms
9x = 180
Divide by 9
9x/9 =180/9
x =20
<1 = 5x = 5*20 = 100
<2 = 4x = 4*20 = 80
Answer:
m1 = 122
m2 = 58
m5 = 68
Step-by-step explanation:
m2 = 180 - 54 - 68 = 58
m1 = 180 - m2 = 180 - 58 = 122
m5 = 180 - 58 - 54 = 68

Because its two base angles are equal
therefore sum of angle in a triangle is equal to 180°

∴∠c=180-70+62
∠c=180-132
∠c=48

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]
I hope it helps you!
