Answer:
B, C
Step-by-step explanation:
x-intercepts are when y=0. f(x) has two x-intercepts at (1, 0) and (5, 0). g(x) also has two x-intercepts; (-3, 0) and (5, 0). So the first one is false, and the second one is true.
The maximum value of f(x) is 2. The maximum value of g(x) is 4. So the third one is true.
The y-intercept is the value of y when x=0. So the y-intercept of f(x) is -1, and the y-intercept of g(x) is 3. So the fourth one is false.
Answer:
v = 8.49 m/s rounded off to 3 significant figures
Step-by-step explanation
Using Energy Conservation
U = Tk + Vp (Sum of kinetic Tk Energy and gravitational potential Vp Energy)
- At height = 3.67 m, the hammer was still or the velocity was negligible; hence, vi = 0 m/s.
- Ui = 0 + mgh
- At ground all potential energy is converted to kinetic; hence, Uf =
mv². - Since total energy of the system remains constant we equate Ui to Uf.
- Ui = Uf
- mgh = mv²
- After cancelling out masses and making v the subject of the formula we get:
v = ![\sqrt[2]{2gh}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B2gh%7D)
= ![\sqrt[2]{2*9.81*3.67}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B2%2A9.81%2A3.67%7D)
= 8.49 m/s rounded off to 3 significant figures
