Which parent functions have a locator/vertex point of (0,0)

Answers

Answer 1

Answer:

Graphing quadratic functions The shortcut to graphing the function f(x) = x2 is to start at the point (0, 0) (the origin) and mark the point, called the vertex. Note that the point (0, 0) is the vertex of the parent function only.

I need help on this question, I can't seem to understand piecewise functions!! ITS SO HARD.​

Answers

Answer:

[tex]f(x)\left \{ {{3x+1 if x\leq 0} \atop {-3x+1 if x>0}} \right.[/tex]

Step-by-step explanation:

So if we first graph the given equation, we'll see the graph I've attached below.

Remember that piecewise functions are functions that change based on the circumstances. I know that sounds super confusing, but it's actually really simple!

In this case, for example, we see the line increasing from -∞ to [tex]0[/tex], and then suddenly going downwards and decreasing. That's a good spot for us to notice because that indicates a change. We notice that the function looks different when [tex]x<0[/tex] or [tex]x>0[/tex]. If you break the function into those two parts, you see that they are just linear equations, but they're only visible when x is either greater than or less than 0.

Now that we notice this pattern, we can find the equation of the lines for both lines.

The points (-3,-8) and (-1,-2) are points on the first line, the one that increases (on the left). We can use those points to find the slope of the first line. Remember the slope equation:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plug in your points:

[tex]m=\frac{-2-(-8)}{-1-(-3)}[/tex]

[tex]m=\frac{6}{2}[/tex]

[tex]m=3[/tex]

So, the slope of the first line is 3. The y-intercept, looking at the graph, is 1. The equation of the first line is [tex]y=3x+1[/tex]. We'll need this later.

Let's do the same thing for the second line. Just looking at the graph, we can see that this is the same exact line, just with a negative slope. So, the equation for the second line is [tex]y=-3x+1[/tex].

So now we can set up a piecewise function.

[tex]f(x)\left \{ {{3x+1} \atop {-3x+1}} \right.[/tex]

The two functions in the bracket are the two different functions used in this graph. Now we need to figure out where each function is effective. Well, they share a y-intercept. Remember that a true function cannot have two points with the same x value. So the first function is effective to the left of x=0, while the second is effective to the right of x=0. In other words, when [tex]x\leq 0[/tex], [tex]f(x)=3x+1[/tex]. But, when [tex]x>0[/tex], [tex]f(x)=-3x+1[/tex]. Now our piecewise function looks like this:

[tex]f(x)\left \{ {{3x+1 if x\leq 0} \atop {-3x+1 if x>0}} \right.[/tex]

And that is our piecewise function for the original function.

I know this is confusing, so please let me know if you have any questions! I hope this helps!

A publishing company is interested in the number of books read each year by people. They send out 50 volunteers to conduct research by collecting random samples of 20 people each and determining the number of books that group read in the previous year. After looking at the sample means, the company estimates that the mean number of books read is 12.4 with a margin of error of 2.4. Based on these values, what interval is likely to contain the true mean number of books read in the previous year by the population?

Answers

Using the confidence interval concept, an interval between 10 and 14.8 is likely to contain the true mean number of books read in the previous year by the population.

What is the interpretation of a x% confidence interval?

It means that it is x% likely that the population parameter(mean/proportion/standard deviation) is between a and b, which are the bounds of the confidence interval.

The bounds of the confidence interval are given by the estimate plus/minus the margin of error.

For this problem, we have that:

The estimate is of 12.4 books.The margin of error is of 2.4 books.

Hence the bounds are given by:

12.4 - 2.4 = 10 books.12.4 + 2.4 = 14.8 books.

An interval between 10 and 14.8 is likely to contain the true mean number of books read in the previous year by the population.

What is the length of segment AD ? How do you know ?

Answers

Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.

Comparing the two circles, the length of segment AD is 4 cm. On the first circle, the diameter is BAE is 8cm.

How to describe a circle?

We should know that a circle is a figure in which all distances are equal from the center and the line from the center to the circumference is called radius.

The diameter is the line that passes through the center of the circle dividing the circle into two equal parts.

The given information are that the circles are the same

Diameter of the circles = 8cm

Radius = D/2= 8/2

Radius = 4 cm in each circle

Since the two circles shave the same diameter of 8cm and segments are different because the second has 3 segments while the first has 2 segments

The length of the segment AD = 4 because its from center to circumference that is radius

The first circle BAE is a diameter because it divides the circle into two equal halves

Therefore the length of segment AD is 4cm because it is a radius.

the diameter is BAE is 8cm.

A bottling process is inspected 100 percent of the time because of the low yield rate of 98%. If a batch of 80 bottles are inspected, what is the probability less than three bottles are bad?

Answers

Answer:

The probability is   [tex]P(X <  3) =  0.7843 [/tex]

Step-by-step explanation:

From the question we are told that

   The low yield rate is  [tex]q = 0.98[/tex]

    The sample size n = 80

Hence the probability that the bottle is bad

       [tex]p = 1- q[/tex]

=>    [tex]p = 1 - 0.98[/tex]

=>     [tex]p =0.02[/tex]

Generally the distribution of yield follows a binomial distribution  

i.e  

         [tex]X  \~ \ \ \  B(n , p)[/tex]

and the probability distribution function for binomial  distribution is  

      [tex]P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

Generally the probability less than three bottles are bad is mathematically represented as

    [tex]P(X <  3) = P(X = 0 ) + P(X = 1 )+ P(X = 2)[/tex]

=>  [tex]P(X <  3) = ^{80}C_0 *  0.02^0 *  (1- 0.02)^{80-0} +^{80}C_1 *  0.02^1 *  (1- 0.02)^{80-1}+ ^{80}C_2 *  0.02^2 *  (1- 0.02)^{80-2}[/tex]

=>  [tex]P(X <  3) = 1 *  1 * 0.1986 + 80 *  0.02 *  0.2027 + 3160 *  0.0004 * 0,2068[/tex]

=>  [tex]P(X <  3) =  0.7843 [/tex]

Chris had a job walking dogs on the weekends. He earned $8.75 per dog. He walked 5 dogs a week for 7 weeks. How much money did Chris earn?

Answers

Answer:

he should be making $306.25

Step-by-step explanation:

what i did was multiply his $8.75 a dog by 5 then multiply it by the 7 weeks

Answer:

Chris's total earning will be: $306.25

Step-by-step explanation:

Given:

Total number of dogs = d = 5

Number of weeks = w = 7

Cost for walking per dog = c = $8.75

First of all, we will calculate his per week cost of walking 5 dogs

Per week cost of walking 5 dogs = d*c = 8.75*5 = $43.75

Then for the cost of 7 weeks, the amount of one week will be multiplied by 7

Total earning will be:

[tex]= 43.75*7 = 306.25[/tex]

Hence,

Chris's total earning will be: $306.25
