○ [tex]\displaystyle None\:of\:these[/tex]
Step-by-step explanation:
[tex]\displaystyle \boxed{y = 2cos\:(2x - \frac{\pi}{2})} \\ y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{\pi}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 2[/tex]
OR
[tex]\displaystyle \boxed{y = 2sin\:2x} \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 2[/tex]
You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 2cos\:2x,[/tex]in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{\pi}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{\pi}{4}} = \frac{\frac{\pi}{2}}{2}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 2cos\:(2x - \frac{\pi}{2}).[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-2\frac{1}{4}\pi, -2],[/tex]from there to [tex]\displaystyle [-1\frac{1}{4}\pi, -2],[/tex]they are obviously [tex]\displaystyle \pi\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle \pi.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 0,[/tex]in which each crest is extended two units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

Trying to factor by splitting the middle term
2.1 Factoring 2t2-15t+22
The first term is, 2t2 its coefficient is 2 .
The middle term is, -15t its coefficient is -15 .
The last term, "the constant", is +22
Step-1 : Multiply the coefficient of the first term by the constant 2 • 22 = 44
Step-2 : Find two factors of 44 whose sum equals the coefficient of the middle term, which is -15 .
-44 + -1 = -45
-22 + -2 = -24
-11 + -4 = -15 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -11 and -4
2t2 - 11t - 4t - 22
Step-4 : Add up the first 2 terms, pulling out like factors :
t • (2t-11)
Add up the last 2 terms, pulling out common factors :
2 • (2t-11)
Step-5 : Add up the four terms of step 4 :

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : 2t-11 = 0
Add 11 to both sides of the equation :
2t = 11
Divide both sides of the equation by 2:
t = 11/2 = 5.500
Solving a Single Variable Equation:
3.3 Solve : t-2 = 0
Add 2 to both sides of the equation :
t = 2

Parabola, Finding the Vertex:
4.1 Find the Vertex of y = 2t2-15t+22
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 2 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,At2+Bt+C,the t -coordinate of the vertex is given by -B/(2A) . In our case the t coordinate is 3.7500
Plugging into the parabola formula 3.7500 for t we can calculate the y -coordinate :
y = 2.0 * 3.75 * 3.75 - 15.0 * 3.75 + 22.0
or y = -6.125-0

Answer:

Step-by-step explanation:
The rule is the number of line which is n. (n-2)*(n-1) divided by 2
The slope of that line through the origin that divides the region bounded is 1.0315
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
given that,
y = 5x - 3x2
5x - 3x2 = 0
x(5 - 3x) = 0
x = 0 , x = 5/3
Area under y = 5x - 3x2 is A = [0 to 5/3] 5x - 3x2 dx
A = [0 to 5/3] 5x2/2 - 3x3/3
A = [0 to 5/3] 5x2/2 - x3
A = 5(5/3)2/2 - (5/3)3 = 125/54
line passing through origin is in the form of y = mx
==> mx = 5x - 3x2
==> 3x2 + mx - 5x = 0
==> 3x2 + x(m -5) = 0
=> x(3x + (m -5)) = 0
==> x = 0 , x = (5 -m)/3
Area under y = 5x - 3x2 and y = mx is (125/54)/2 = 125/108
==> ?[0 to (5 -m)/3] 5x - 3x2 -mx dx = 125/108
==> ?[0 to (5 -m)/3] (5 - m)x - 3x2 dx = 125/108
==> [0 to (5 -m)/3] (5 - m)x2/2 - x3 = 125/108
==> (5 - m)[(5 -m)/3]2/2 - ((5 -m)/3)3 = 125/108
==> (5 -m)3/18 - (5 -m)3/27 = 125/108
==> (5 -m)3/54 = 125/108
==> (5 -m)3 = 125/2
==> (5 -m) = 3.9685
==> m = 5 - 3.9685
==> m = 1.0315
Hence slope of line = 1.0315

What does how many hours did he rent the bike for?
Add
Subtract
Divide
Multiply
Answers
Answer:
He rented the bike for 2 hours.
Step-by-step explanation:
Since a bike costs $13 plus $5 per hour, we can write this as:
13 + 5(h)
We used "h" as the variable for hours, since we need to find how many hours he rented the bike for, that he had to pay $23.
And since Pete paid $23, we need to make the other equation equal to 23.
= 23
So the actual equation, would look like this:
13 + 5(h) = 23
Now we just solve for h in the equation:
13 + 5(h) = 23
Step 1: Multipy 5 times "h"
13 + 5h = 23
Step 2: Subtract 13 from both sides
13 + 5h - 13 = 23 - 13
Step 3: Simplify
5h = 10
Step 4: Divide both sides by 5
5h/5 = 10/5
Step 5: Simplify
h = 2
So the number of hours that Pete rented the bike for 2 hours
Peremeter=34 Area=60, What are the sides???
Answers
Answer:
Step-by-step explanation:
I'm going to assume it is a rectangle.
P = 2L + 2w = 34
Area = L * w = 60 Divide by L
w = 60/L Substitute into the perimeter.
P = 2L + 2w = 34 Put (60/L) for w
P = 2L + 2(60)/L = 34 Multiply both sides by L
P = 2L^2 + 120 = 34L Subtract 34L from both sides.
2L^2 - 34L + 120 = 0 Divide everything by 2
L^2 - 17L + 60 = 0 Factor
(L - 5)(L - 12) = 0
Since L is usually the larger value, use L = 12
L*w = 60
12w = 60
w = 60/12
w = 5

L = 12w = 5If a 5 kg ball is accelerating 1.2 m/s squared, what is the force on it? plss do it now

Answer:
Second option: y = 5(x + 2)
Step-by-step explanation:
Equation that is already graphed: y = 5x - 10
Let's use the second option: y = 5(x + 2)
Since y = 5x - 10, we substitute 5x - 10 into the equation y = 5(x + 2)
The equation will look like this: 5x - 10 = 5(x + 2)
Now we solve: 5x - 10 = 5(x + 2)
5x - 10 = 5(x + 2)
Distribute
5x - 10 = 5x + 10
Rearrange variables to the left side of the equation
5x - 5x = 10 + 10
Apply the inverse property of addition
0 = 10 + 10
Add 10 and 10

Answer:
D (195,500,000)
Step-by-step explanation:
8.5 mil times 23 equals D
The number of people living in Brazil that year was approximately 195,500,000 people. The answer is the last option 195,500,000 people
What is Population density?From the question, we are to determine the number of people living in Brazil in that year
From the given information,
Brazil land area = 8.5 million square kilometers = 8500000 km²
Brazil population density = Peru population density = 23 people /km²
From population density formula,
[tex]Population\ density = \frac{Number \ of \ people}{Land\ area}[/tex]
Then,
Number of people = Population density × Land area
Therefore,
Number of people living in Brazil = 8500000 × 23
Number of people living in Brazil = 195,500,000 people
Hence, the number of people living in Brazil that year was approximately 195,500,000 people. The answer is the last option 195,500,000 people

Some satellites are called 'geo-stationary' - they seem to hover above the earth, as they remain 36,000 km above a single point on the earth's surface and spin with the earth as it rotates. How much time would such a satellite take to complete one revolution of the earth?
Answers
Answer:
24 hours
Step-by-step explanation:
This is because they seem to be stationary about one point on the surface of earth. This is possible when the satellite has the same angular speed as the earth.
This means that it takes the same amount of time to the satellite to take one revolution around the earth as it takes the earth to take one revolution about its axis.
[tex]w=\frac{revolutions}{time}[/tex]
[tex]w_{satellite}=w_{earth}[/tex]
[tex]\frac{N_{satellite}}{t_{satellite}}=\frac{N_{earth}}{t_{earth}}[/tex]
since [tex]N_{satellite}=N_{earth}[/tex]
then, when solving for t we get that:
