The function below was generated using an equation of the form f(x) = asin(bx – c). On a coordinate plane, a function has a maximum of 3 and minimum of negative 3. It completes one period at pi. It increases through the y-axis at (0, 0). Find a, b, and c for the function such that the graph of f matches the figure. a = 3, b = –2, c = π a = 2, b = 3, c = –π a = 3, b = 2, c = –π a = 2, b = -3, c = π

Answers

Answer: A

a = 3, b = –2, c = π

Step-by-step explanation:

The values of a, b and c for the function such that the graph of f matches the figure are;

a = 3, b = -2, c = π

We are given the equation as;

f(x) = a sin(bx - c)

Now, the general form of equation of a sinusoidal wave is;

y = Asin(ωt + ϕ)

Where;

A is the amplitude of the wave

ω is the wave's angular frequency,

ϕ is the phase of the sine wave in radians.

Comparing that general equation to the one we are given, we have;

a as the amplitude

c as the phase

Now, from the attached image of the graph, the amplitude it the peak of the wave which is 3.

Thus; a = 3

Now, the phase angle from the graph which is the interval for each period of motion of the wave is seen to be π. Thus, c = π

Looking at the options, the only one that has the correct value of a and c is option A.

Answers

Answer:

this is a system of equations , and it's no surprise that it's tricky for you. these are tricky for anyone.

Step-by-step explanation:

X=adults

Y=children

I only know to make these two equations from experience doing these types of questions.

X+Y=800

7X +5Y=4600

there are a few ways to solve this , i"m just going to multiply the first equatlion by 7 and the subtract  the 2nd  from that whole equation.

7(X +Y=800)

7X +7Y = 5600

-(7X +5Y =4600)

0X +2Y = 1000

Y  = 500   ( 500 children went to the movies )

by inspection  you can probably see that 300 adults had to go too

500 kids

300 parents

also that's 4600 dollars to let those people in

7(300) + 5(500) = 4600

2100 + 2500 = 4600

the length of the swimming pool is 8 m longer than its width and the area is 105 m squared write in quadratic equation ​

Answers

Answer:

Step-by-step explanation:

The length of the swimming pool is 8m longer than it's width.

If we say L = length, W = width

From the information above, we can say

L= 8 + w

We are also told the area is 105 m squared.

Note:

Area of a Rectangle = Length x Width

105 =  (8 + w ) x w

[tex]105 = 8w + w^2\\[/tex]

Subtract 105 from both sides:

[tex]w^2 + 8w - 105 = 0[/tex]

Answer: Choice B

h(c) = 1 for at least one c between -3 and 4

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

Explanation:

Draw an xy axis system. Plot the points (-3,-1) and (4,2) on this grid. These points come from the fact that h(-3) = -1 and h(4) = 2. These are the endpoints of the h(x) function.

Next, draw horizontal lines through both points. Also, draw vertical lines through the two points as well. A rectangle will form.

The region inside this rectangle is all we care about.

We're told that h(x) has endpoints mentioned earlier, and h(x) is continuous, so that means we have some curve or line through the two points. One such example is shown below. There are infinitely many possible curves to draw out as long as they stay in the rectangle.

----------------------

After you have your h(x) function curve drawn, draw a horizontal line through y = 1 on the y axis. This is the dashed line in the diagram below.

This horizontal line crosses the green h(x) curve at one point or more. In my example, it does so at one point only. However, you could easily draw h(x) so that it crosses y = 1 as many times as you want (just have it squiggle up and down multiple times).

This shows that h(c) = 1 is possible when [tex]-3 \le c \le 4[/tex]. Here c is playing the role of x since it is the input of a function. The h(c) is the output, so that's the y value.

This says that for some input between -3 and 4, it's possible to get an output of 1.

-------------------------

Here's a real world example of the intermediate value theorem.

Let's say the endpoints are A and B, and they are two towns.

The h(x) curve is a road connecting the towns.

To go from A to B, or vice versa, we need to cross over some border that is between the towns. The border in this case is the dashed horizontal line in the diagram.

side note: A special use of the intermediate value theorem is to show that a root exists on some interval (if you know the function changes between positive to negative, or vice versa).

Answer:

Kindly check explanation

Step-by-step explanation:

3 boxes or less = Cost of tiles = $48

4 - 8 boxes ;  cost = $45

9 - 19 boxes ; cost = $42

> 19 boxes ; cost = $38

Cost of purchasing 5 boxes of tiles :

$45 * 5 = $225

My parents came here from Colombia during a time of great instability there. Escaping a dire economic situation at home, they moved to New Jersey, where they had friends and family, seeking a better life, and then moved to Boston after I was born. Throughout my childhood I watched my parents try to become legal but to no avail. They lost their money to people they believed to be attorneys, but who ultimately never helped. That meant my childhood was haunted by the fear that they would be deported. If I didnt see anyone when I walked in the door after school, I panicked. And then one day, my fears were realized. I came home from school to an empty house. Lights were on and dinner had been started, but my family wasnt there. Neighbors broke the news that my parents had been taken away by immigration officers, and just like that, my stable family life was over. Not a single person at any level of government took any note of me. No one checked to see if I had a place to live or food to eat, and at 14, I found myself basically on my own. While awaiting deportation proceedings, my parents remained in detention near Boston, so I could visit them. They would have liked to fight deportation, but without a lawyer, and with an immigration system that rarely gives judges the discretion to allow families to stay together, they never had a chance. Finally, they agreed for me to continue my education at Boston Arts Academy, a performing arts high school, and the parents of friends graciously took me in. I was lucky to have good friends, but I had a rocky existence. I was always insecure about being a nuisance and losing my invitation to stay. I worked a variety of jobs in retail and at coffee shops all through high school. And, though I was surrounded by people who cared about me, part of me ached with every accomplishment, because my parents werent there to share my joy. My family and I worked hard to keep our relationships strong, but too-short phone calls and the annual summer visits I made to Colombia didnt suffice. They missed many important events in my life, including my singing recitalsthey watched my senior recital on a tape I sent them instead of from the audience. And they missed my prom, my college application process and my graduations from high school and college. My story is all too common. Every day, children who are U.S. citizens are separated from their families as a result of immigration policies that need fixing. I consider myself lucky because things turned out better for me than for most, including some of my own family members. When my brother was deported, his daughter was just a toddler. She still had her mother, but in a single-parent household, she faced a lot of challenges. My niece made the wrong friends and bad choices. Today, she is serving time in jail, living the reality that I act out on screen.* I dont believe her life would have turned out this way if her father and my parents had been here to guide and support her. I realize the issues are complicated. But its not just in the interest of immigrants to fix the system: Its in the interest of all Americans. Children who grow up separated from their families often end up in foster care, or worse, in the juvenile justice system despite having parents who love them and would like to be able to care for them. I dont believe it reflects our values as a country to separate children and parents in this way. Nor does it reflect our values to hold people in detention without access to good legal representation or a fair shot in a court of law. President Obama has promised to act on providing deportation relief for families across the country, and I would urge him to do so quickly. Keeping families together is a core American value. Congress needs to provide a permanent, fair legislative solution, but in the meantime families are being destroyed every day, and the president should do everything in his power to provide the broadest relief possible now. Not one more family should be separated by deportation. From "My Parents Were Deported" by Diane Guerrero (Copyright Diane Guerrero, 2014). Who settled the lands of east, central, and South Africa?
