The correct graphs which represents a function is shown in ''Option B.''

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

There are four graphs are shown in image.

Now, We can check all the graph by vertical line test.

If the vertical line cut only at one point of the graph, then, it shows the function.

If the vertical line cut more than one point of the graph, then, it cannot shows the function.

Hence, By vertical line test,

The correct graphs which represents a function is shown in Option B.

Answer:

Yes, this is a function.

No, this is not a linear function.

Step-by-step explanation:

A function is a process or a relation that associates each element x of a set X, the domain of the function, to a single element y of another set Y

Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.

Answer:

y=31.

Step-by-step explanation:

y= mx - b

y= (7)(6)-(11)

y= 42-11

y=31.

Hey there!

y = mx - b

mx - b = y

7(6) - 11 = y

42 - 11 = y

31 = y

Therefore, your answer is: y = 31

Good luck on your assignment & enjoy your day!

Answer:

Only option D is one of the transformations needed.

Step-by-step explanation:

The graph of f(x)=x^2 is a positive parabola with x=0 as the zero in ordinates and also 0 as a zero x. This is, the graph passes in (0,0) and this is the only point it crosses both axis, then for every x value we will gave a positive f(x).

Here I attach a graph that shows both, f(x)=x^2 and g(x)=-x^2+16x-44.

As you can see, for transforming f(x) in g(x) we need to reflect it over the x axis, as g is open downwards. Then, as the quadratic term is still being x^2 we do not wide it (as you see in the graph both curves are equally widened).

Then, we can also see that the graph is shifted right, so we do not shift it left 8 units (notice that we shift it right 8 units).

So, after reflecting over the x axis and shifting right we need to shift it UP, as we can see the graph is over the x axis.

So, the three transformations needed are:

1. reflect over the x axis

2. shift right 8 units

3. shift up 20 units.

So, from the options you proposed we chose only d, to which we MUST add the transformations noted above.

Sorry for the mistake!

Answer:Coupon B gives the lower price. The price of coupon B is $4.4 less than the price of coupon A.

Step-by-step explanation:

The coupon B gives the lower price. That means by using coupon B, Ann will get a chair at $33.

The price with coupon B is $2.75 less than the price with coupon A.

A coupon is a ticket or document that can be redeemed for a financial discount or rebate when purchasing a product.

A percentage is a proportion that shows a number as parts per hundred

To convert a percent into a number divide the given percentage by hundred and remove the percentage sign.

According to the given question.

Ann has two coupon for a Chair.

Coupon A is giving 35 percent off on a chair of $55.

And, coupon B is giving $22 0ff on chair 0f $55

If Ann uses coupon A then the amount she have to pay for chair is given by

Amount = [tex]55-\frac{35}{100} ($55)[/tex]

Amount = [tex]55-0.35(55)[/tex]

Amount = [tex]55-19.25[/tex]

Amount = $35.75

If Ann uses coupon B then the amount she have to pay for chair is given by

Amount = $55 - $22

Amount = $33

Hence, the coupon B gives the lower price. That means by using coupon B, she will get a chair at $33.

Since, through coupon A the amount she have to pay is $35.75 and through B she have to pay the amount of $33.

Now, $35.75 - $33 = $2.75

Thus, the price with coupon B is $2.75 less than the price with coupon A.

Step-by-step explanation:

289.76-54.88-54.88=180/2=90

Perimeter is the sum of the length of the sides used to make the given figure. The length of the field is 90 meters.

Perimeter is the sum of the length of the sides used to make the given figure.

Given that the width of the field is 54.88 meters and the perimeter of the field is 289.76 meters. Therefore, we can write the perimeter as,

Perimeter = 2(Length + Width)

289.76 meters = 2(Length + 54.88 meters)

289.76meters / 2 = Length + 54.88 meters

144.88metes = Length + 54.88 meters

Length = 144.88 meters - 54.88 meters

Length = 90 meters

Hence, the length of the field is 90 meters.

[tex]\frac{dA}{dt} = 2\pi r(\frac{dr}{dt})[/tex]

Step-by-step explanation:

Your solution is correct (See explanation):

Area (A) of a circle is

[tex]A = \pi r^2[/tex]

Where

[tex]r = radius[/tex]

Differentiate both sides with respect to t

[tex]\frac{dA}{dt} = 2\pi r(\frac{dr}{dt})[/tex]

This is so because, we have to differentiate A on the left hand side and r on the right hand side because [tex]2\pi[/tex] is a constant

Hence, your solution is correct and and

Answer:

5x^2y is the GCF for 15x2y3 and -20x3yz.

Step-by-step explanation:

Answer:

We use students' t distribution therefore degrees of freedom is v= n-2

Step-by-step explanation:

Confidence Interval Estimate of Population Regression Co efficient β.

To construct the confidence interval for β, the population regression co efficient , we use b, the sample estimate of β. The sampling distribution of b is normally distributed with mean β and a standard deviation σ.y.x / √(x-x`)². That is the variable z = b - β/σ.y.x / √(x-x`)² is a standard normal variable. But σ.y.x  is not known so we use S.y.x and also student's t distribution rather than normal distribution.

t= b - β/S.y.x / √(x-x`)² = b - β/Sb    [Sb = S.y.x / √(x-x`)²]

with v= n-2 degrees of freedom.

Consequently

P [ - t α/2<  b - β/Sb  < t α/2] = 1- α

or

P [ b- t α/2 Sb<   β  < b+ t α/2 Sb] = 1- α

Hence a 100( 1-α) percent confidence for β the population regression coefficient for a particular sample size n <30  is given by

b± t α/2 Sb

Using the same statistic a confidence interval for α can be constructed in the same way for  β  replacing  a with b and Sa with Sb.

a± t α/2 Sa

Using the t statistic  we may construct the confidence interval for U.y.x for the given value X0 in the same manner

Y~0 ± t α/2(n-2) SY~

Y~0= a+b X0
