PLS HELP, 50 POINTS!!!
Sedaia [141]

Answer:

Part A: From 0 to 2 seconds, the height of the water balloon increases from 60 to 75 feet, therefore the water balloon's height is increasing during the interval [0,2]

Part B: From 2 to 4 seconds, the height of the water balloon stays the same at 75 feet, therefore the water balloon's height is the same during the interval [2,4] From 10 to 12 seconds, the height of the water balloon stays the same at 0 feet, therefore the water balloon's height is the same during the interval [10,12] From 12 to 14 seconds, the height of the water balloon stays the same at 0 feet, therefore the water balloon's height is the same during the interval [12,14] 

Part C: The interval, [4,6] of the domain is when the water ballon's height decreases the fastest. The interval [4,6] decreases by 35 feet. The two other intervals that decrease are [6,8] and [8,10] which both have the same slope. They decrease by 20 feet. Therefore, this helps us conclude that the interval [4,6] decreases the fastest because 35 feet is a more significant decrease than 20 feet. 

Part D: I predict that the height of the water balloon at 16 seconds is 0 feet. This is because at 10-14 seconds, the water balloon's height is 0 feet. In read-world situations, if the water balloon is on the ground which is 0 feet, it stays on the ground due to gravity. 

Step-by-step explanation:

I hope this helps! I also do not know if it is all correct but I did research and everything so hopefully it is correct! Good luck!

How do you solve this question?
aliya0001 [1]
We can use the quadratic formula to solve this problem.

\sf x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

You've already listed the values for 'a', 'b', and 'c', so just plug them into the formula:

\sf x=\dfrac{-(-12)\pm\sqrt{(-12)^2-4(4)(9)}}{2(4)}

Simplify:

\sf x=\dfrac{12\pm\sqrt{144-4(4)(9)}}{8}

Multiply:

\sf x=\dfrac{12\pm\sqrt{144-144}}{8}

Subtract:

\sf x=\dfrac{12\pm\sqrt{0}}{8}

Take the square root:

\sf x=\dfrac{12\pm 0}{8}

It doesn't matter if you add or subtract something with 0, you'll end up with the same thing, so we have:

\sf x=\dfrac{12}{8}\rightarrow\boxed{\sf 1\dfrac{1}{2}}

What is the ratio for sin Y if tan Y = 8/15?
jeyben [28]

Answer: 8/17

Step-by-step explanation: The ratio for tangent is opposite/adjacent. The side opposite from Y has a length of 8, and the side next to it has a length of 15. These are the lengths of the legs of the triangle. To find the sine ratio, you need the hypotenuse.

The hypotenuse can be found using the Pythagorean theorem. 8^2=64 and 15^2=225. 225+64=289. The square root of 289 is 17. The hypotenuse has a length of 17.

The ratio for sine is opposite/hypotenuse. Take the value of the opposite from the tangent ratio (8) and the length of the hypotenuse (17) to get 8/17.
