Answer: A

Step-by-step explanation:

The quotient is x² + 4x +3. Then the correct option is A.

A quotient in mathematics is the amount created by dividing two numbers. In mathematics, the term "quotient" is frequently used to refer to the integer portion of a division, as well as to a fraction or a ratio.

The quotient is calculated as:-

x - 5 ) x³ - x² - 17x -15 ( x² + 4x + 3

         -x³  + 5x²

      _________________

          4x² - 17x - 15

         -4x² + 20x

       _________________

                   3x -15

                 -3x + 15

       _________________

                         0

Hence, the quotient is  x² + 4x +3.

Answer:

51

Step-by-step explanation:

PEMDAS means parenthesis (there are none), exponents (there are none), multiplication. So you multiply 8x18 to get 144. Then you have division, so 144/4 is 36. Finally, you add this number to 15 to get 51 as your final answer.

By PEMDAS, the solution of the expression 8x18÷4+15 is 51.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Given:

An expression,

8x18÷4+15.

In order to solve the problem by PEMDAS:

First, solve the multiplication operation,

144÷4+15

Now, solving division operations,

36 + 15

Applying addition operation,

51

Therefore, 51 is the solution to the expression.

Answer:

14.0362 degrees (round to 14.0 degrees)

Step-by-step explanation:

1. Assume that the math can be deduced by the sides of a triangle due to the "sightline" nature of the problem. This is a classic trig problem you will see.

2. The base of the triangle would be 12 feet and one of the legs of the triangle will be 3 feet.

3. Arctangent will provide the angle of elevation. The equation can be written as arctan(h/b), in this case h = height and b = base.

4. The calculation will be arctan(3/12) which translates to 14 degrees which is, fortunately, the angle of elevation.

I recommend trying this method out with another example such as the angle of elevation between you and the next plane you see in the sky. For example, the height difference between you and the plane is 7 miles and the plane is x miles away. Again we can create a simple triangle to discover many interesting details.

Answer:

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

Step-by-step explanation:

Part A

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

Part B

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

We already know our amplitude of [tex]a=3[/tex] from part A.

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

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 [tex]sin(x)=cos(x-\frac{\pi}{2})[/tex] which shifts the cosine graph [tex]\frac{\pi}{2}[/tex] units to the right. This means that [tex]c=-\frac{\pi}{2}[/tex], making our phase shift [tex]-\frac{c}{b}=-\frac{-\frac{\pi}{2}}{\frac{\pi}{13}}=6.5[/tex], or 6.5 feet to the right

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

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

Part C

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).

Part A

The distance from the highest and lowest point is 6 feet. Cut this in half to find the amplitude: 6/2 = 3. The amplitude represents the vertical distance from the midline (aka average height) to either the peak or valley points.

The period is 26 seconds because this is the time difference from one max height to the next max height. This is one of a few ways to measure a full cycle. Another way is from min height to the next min height.

==========================================================

Part B

In this case, the template for cosine is

h = Acos(B(t-C))+D

We found the amplitude A = 3 from the previous section.

The period is T = 26 which means B = 2pi/T = 2pi/26 = pi/13

D = 12 because the average height is 12 feet. The average height is always on the midline.

We are told that t = 0 leads to h = 12, so,

[tex]h = A\cos\left(B\left(t-C\right)\right)+D\\\\h = 3\cos\left(\frac{\pi}{13}\left(t-C\right)\right)+12\\\\12 = 3\cos\left(\frac{\pi}{13}\left(0-C\right)\right)+12\\\\3\cos\left(\frac{\pi}{13}\left(-C\right)\right) = 0\\\\\cos\left(\frac{\pi}{13}C\right) = 0\\\\[/tex]

Let's isolate the C term

[tex]\cos\left(\frac{\pi}{13}C\right) = 0\\\\\frac{\pi}{13}C = \arccos(0)\\\\\frac{\pi}{13}C = \frac{\pi}{2}\\\\C = \frac{\pi}{2}*\frac{13}{\pi}\\\\C = \frac{13}{2}[/tex]

==========================================================

Part C

A full period is 26 seconds.

At t = 0 the bottle is at a height of 12 feet

26 seconds later, the bottle is back again at 12 feet to repeat another cycle indefinitely.

At every quarter cycle, the object is either at a min point, max point, or at the average (midline).

So every 26/4 = 6.5 seconds the object will be in one of those places.

In this case, the object starts at 12 feet, goes up to the max 15 feet when t = 6.5

Then another 6.5 seconds later it's back to the midline again. Another 6.5 seconds later (total time is now 6.5*3 = 19.5 seconds) the bottle dips down to the min height of 9 feet. You should see that (19.5, 9) is one of the infinitely many minimum points on this particular cosine curve.
