Answer:
Option B.
.
Step-by-step explanation:
The given equation is kx - 4 = 9
We will add 4 on both the sides of the equation
kx - 4 +4 = 9 +4
kx = 13
Now we will divide by k on both the sides of the equation
![x = \frac{13}{k}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B13%7D%7Bk%7D)
Therefore Option B x = 13/k is the right answer.
They are inverse functions though to be completely thorough your teacher should have also put g(f(x)) = x as well. Though I can see what your teacher is aiming for at least.
The idea is that whatever the output of g(x) is, it's plugged into f(x) and the initial input is the result. So g(x) takes a step forward and f(x) takes a step back undoing everything g(x) did. Which is exactly what an inverse operation does.
The answer is 6 centimeters
Answer:
The scanning electron microscope
Step-by-step explanation:
The scanning electron microscope can determine the proximity to a discharging firearm and/or the contact with a surface exposed to GSR
<u>Answer:</u>
The Kinetic energy of the 110 kg linebacker is 1375 J
<u>Solution:</u>
The kinetic energy of an object is the energy produced by its velocity. Kinetic energy of an object is directly proportional to the mass and the square of the its velocity.
Therefore, the formula for kinetic energy is
![KE=\frac{1}{2} \times m v^{2}](https://tex.z-dn.net/?f=KE%3D%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20m%20v%5E%7B2%7D)
Here, The linebacker’s mass m = 110 kg
The linebacker’s velocity v = 5 m/s
So by substituting the values,
The kinetic energy of linebacker is
![K E=\left(\frac{1}{2} \times 110 \times 5 \times 5\right) \text { Joules } \\\\ \Rightarrow (\frac{2750}{2}) Joules = 1375 Joules](https://tex.z-dn.net/?f=K%20E%3D%5Cleft%28%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20110%20%5Ctimes%205%20%5Ctimes%205%5Cright%29%20%5Ctext%20%7B%20Joules%20%7D%20%5C%5C%5C%5C%20%5CRightarrow%20%28%5Cfrac%7B2750%7D%7B2%7D%29%20Joules%20%3D%201375%20Joules)
