Answer:

6x²y+2xy²-4x²

Step-by-step explanation:

Like terms are terms that have the same variables and exponents.

In the given problem, the only like terms are 10x²y and -4x²y; adding these gives us 6x²y.  Bringing down the rest of the terms gives us

6x²y+2xy²-4x²

Answer:

The angle between the 190 ft. side and the 330 ft. side is 57.9^o

Step-by-step explanation:

<u>The Law of Cosines</u>

When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and \alpha is the angle formed by sides a and b (opposite to c), then

\displaystyle c^2=a^2+b^2-2ab\ cos\alpha

We'll use the values a=190, b=330, c=280 because we want to compute the angle opposite to c

\displaystyle cos\alpha =\frac{a^2+b^2-c^2}{2ab}

\displaystyle cos\alpha =\frac{190^2+330^2-280^2}{2(190)(330)}

\displaystyle cos\alpha =\frac{36100+108900-78400}{125400}

\displaystyle cos\alpha =\frac{66600}{125400}=0,5311

\displaystyle \alpha= arccos\ 0.5311

\boxed{\displaystyle \alpha= 57.9^o}

1..A message in a bottle is floating on top of the ocean in a periodic manner. The time between periods of maximum heights is 26
statuscvo [17]

Answer:

See below for answers and explanations (along with a graph attached)

Step-by-step explanation:

<u>Part A</u>

The amplitude of a sinusoidal function is half the distance between the maximum and the minimum. It is given to us that the distance from the highest and lowest point is 6 feet, so our amplitude is 6/2 = 3 feet

<u>Part B</u>

The graph's function would be in the form of y=acos(bx+c)+d where a is the amplitude, \frac{2\pi}{b} is the period, -\frac{c}{b} is the phase/horizontal shift, and d is the average/midline.

We already know our amplitude of a=3 from part A.

Since our period is given to us as 26 seconds, then we can use the equation \frac{2\pi}{b}=26 to find b, which happens to be b=\frac{\pi}{13}.

Since the cosine function starts at its maximum and we want it to start at the average where the bottle travels up, we would need to use the cofunction identity sin(x)=cos(x-\frac{\pi}{2}) which shifts the cosine graph \frac{\pi}{2} units to the right. This means that c=-\frac{\pi}{2}, making our phase shift -\frac{c}{b}=-\frac{-\frac{\pi}{2}}{\frac{\pi}{13}}=6.5, or 6.5 feet to the right

Our average/midline would be d=12 as given as the average height by the problem.

Therefore, the function is f(x)=3cos(\frac{\pi}{13}x-\frac{\pi}{2})+12

<u>Part C</u>

Using our determined function from Part B, by looking at its graph, we see that the bottle will reach its lowest height of 9 feet after 19.5 seconds (see attached graph).
