The domain of the function is (-∞, -8) and (-8, ∞). Then the range of the function will be (-∞, 0) and (0, ∞).
<h3>What are domain and range?</h3>
The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
y = 3/(x + 8)
Then the domain of the function is (-∞, -8) and (-8, ∞). Then the range of the function will be (-∞, 0) and (0, ∞).
More about the domain and range link is given below.

Answer:
15.3 m/s
Step-by-step explanation:1) Find the gravitational potential energy using the equation :
![PE_g=mgh](https://tex.z-dn.net/?f=PE_g%3Dmgh)
![PE_g=2.5(12)(9.8)\\PE_g=294](https://tex.z-dn.net/?f=PE_g%3D2.5%2812%29%289.8%29%5C%5CPE_g%3D294)
2) Then use the equation for kinetic energy to solve for the velocity:
![KE=\frac{1}{2} mv^{2}](https://tex.z-dn.net/?f=KE%3D%5Cfrac%7B1%7D%7B2%7D%20mv%5E%7B2%7D)
![294=\frac{1}{2}(2.5)(v^2)\\235.2=v^2\\\sqrt{235.2} =v\\15.3 m/s=v](https://tex.z-dn.net/?f=294%3D%5Cfrac%7B1%7D%7B2%7D%282.5%29%28v%5E2%29%5C%5C235.2%3Dv%5E2%5C%5C%5Csqrt%7B235.2%7D%20%3Dv%5C%5C15.3%20m%2Fs%3Dv)
Answer:
no it doesn't
Step-by-step explanation:
Use the Pythagorean theorem(a^2 + b^2 = c^2) to find out if 3 sides will form a right angle.
Hope this helps!! :D
Answer: A
Step-by-step explanation: This is because the first line goes forward 4.5 and the second line moves it back 2.5 and 4.5-2.5 is 2 which is the endpoint of answer a
