3x + 12 I’m guessing not sure if it’s right
Answer:
<em>(D). (3, 1) </em>
Step-by-step explanation:
y ≤ 3x - 4
<u><em>(A). (0, 4)</em></u>
4 ≤ 3(0) - 4
4 ≤ - 4 <u><em>(False statement)</em></u>
<u><em>(B). (-2, 0)</em></u>
0 ≤ 3(- 2) - 4
0 ≤ - 10 <u><em>(False statement) </em></u>
<u><em>(C). (0, 0)</em></u>
0 ≤ 3(0) - 4
0 ≤ - 4 <u><em>(False statement)</em></u>
<u><em>(D). (3, 1)</em></u>
1 ≤ 3(3) - 4
1 ≤ 5 <u><em>(True statement) </em></u>
<h3>Answer:</h3><h3>T
wo possible smallest and largest angles are 11.78° and 78.22°.</h3>
Step-by-step explanation:
Minigolf ball will follow a trajectory to get into the hole.
Since range of a trajectory is calculated by the formula,
![R=\frac{u^{2}sin2\theta}{g}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7Bu%5E%7B2%7Dsin2%5Ctheta%7D%7Bg%7D)
Where u = initial speed of the ball
θ = angle between the hole and direction in which the ball has been projected
g = gravitational pull
Now we plug in the values in the formula,
![2=\frac{7^{2}sin(2\theta)}{9.8}](https://tex.z-dn.net/?f=2%3D%5Cfrac%7B7%5E%7B2%7Dsin%282%5Ctheta%29%7D%7B9.8%7D)
sin2θ = ![\frac{2\times 9.8}{49}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%209.8%7D%7B49%7D)
2θ = ![sin^{-1}(0.4)](https://tex.z-dn.net/?f=sin%5E%7B-1%7D%280.4%29)
2θ = 23.57° or 156.43°
θ = 11.78° or 78.22°
Hence two possible smallest and largest angles are 11.78° and 78.22°.
Answer:
you can't cheat in an online school math test =_=
Step-by-step explanation:
Answer:
4 weeks
Step-by-step explanation:
2 1/4 = 9/4 = 2.25
if it grows 2.25 inches in one week then in two weeks it would have grown 4.5 inches
keep adding the 2.25 inches to 14 until u get 23
:) hope this was heplful
