The more people living in an area, the more likely it is that public buses will be used. city a has a population of 51,242 and covers an area of 89.22 mi2. city b has a population of 50,178 and covers an area of 8.12 mi2. which statement about use of public buses in the cities is most likely true? the residents of city a are more likely to use public buses because their city has a greater population density. the residents of city b are more likely to use public buses because their city has a greater population density. the residents of both cities are equally likely to use public buses because both population densities are about the same. the residents of both cities are unlikely to use public buses because both population densities are too high.

Prime polynomials cannot be factorized in smaller degree polynomials. The prime polynomials out of the considered option are:

Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.

(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)

Checking all the options for them being prime or not:

Take [tex](x+a)(x+b) = x^2 + 9[/tex]

Then, expanding it gives:

[tex]x^2 + (a+b)x + ab = x^2 + 9 \implies a+b = 0, ab = 9[/tex]

or we get: [tex]a = -b, ab = -b^2 = 9, b^2 = -9[/tex]

Square of a real number doesn't exist, so this factor doesn't exist. Thus, it is prime polynomial.

We have the identity [tex](a+b)(a-b) = a^2 - b^2[/tex]

and since 9 is square of 3, therefore, we get:

[tex]x^2 -9 = x^2 -3^2 = (x+3)(x-3)[/tex]

So it got factorized. Thus, not a prime polynomial.

Take [tex](x+a)(x+b) = x^2 + 3x + 9[/tex]

Then, expanding it gives:

[tex]x^2 + (a+b)x + ab = x^2 + 3x + 9 \implies a+b = 3, ab = 9[/tex]

That gives:

[tex]a = 3-b\\ab = b(3-b) = 3b - b^2 = 9\\b^2 -3b + 9 = 0[/tex]

Solving this quadratic equation by root formula gives:

[tex]b = \dfrac{-(-3) \pm \sqrt{(-3)^2 -4(1)(9)} }{2}\\\\b = \dfrac{-(-3) \pm \sqrt{-27} }{2}\\[/tex]

this makes 'b' a complex number and it doesn't remain a real number as its expression contains square root of a negative number.

Thus, this polynomial cannot be factorized in terms of smaller degree polynomials. Thus, its a prime polynomial.

Taking -2 common out, we get:

[tex]-2(x^2 - 4) = -2(x^2 - 2^2) = -2(x-2)(x+2)[/tex]

Thus, it got factorized, and therefore not a prime polynomial.

Thus, the prime polynomials out of the considered option are:

The area of the circle that contains the sector is 546.5 in² (rounded to the nearest tenth)

From the question, we are to determine the area of the circle.

The area of a circle can be determined by using the formula,

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

From the given information,

Area of the sector = 167 in²

Arc measure = 110°

Using the formula,

[tex]Area\ of\ sector = \frac{\theta}{360 ^\circ} \times \pi r^{2}[/tex]

Then,

[tex]167= \frac{110 ^\circ}{360 ^\circ} \times \pi r^{2}[/tex]

[tex]167= \frac{11}{36} \times \pi r^{2}[/tex]

[tex]\pi r^{2} =\frac{167 \times 36}{11}[/tex]

[tex]\pi r^{2} = 546.5 \ in^{2}[/tex]

Since area of the circle, A, is given by πr²

Then,

A = 546.5 in²

Hence, the area of the circle that contains the sector is 546.5 in²

Answer:

$694.06

Step-by-step explanation:

OG price= 1,029

discount=.05

sales tax =.065

1/3(og price)=1/3(1029)=343

one third of $1,029 is 343, hence we take off $343 from the orginial price

1029-343= $686--> sales price

.05*salesprice= .05*686=34.3

subtract 5% discount: 686-34.3= $651.71

=find 6.5% tax: .065*651.71= $42.36

add 6.5% tax:  651.81+42.36=694.06

scatter plot of options A and D.

A scatterplot is a type of graphical display that is used to represent the relationship between two continuous variables.

In a scatterplot, each point represents the values of the two variables, with one variable being plotted along the x-axis and the other variable being plotted along the y-axis.

The position of each point on the graph represents the values of both variables for that particular observation.

We have,

The line of best fit, also known as the regression line, is a straight line that is drawn through a scatter plot of data points to represent the trend or relationship between two variables.

In a scatter plot, the horizontal axis represents one variable, and the vertical axis represents the other variable.

The line of best fit is drawn in such a way that it minimizes the distance between the line and the data points.

We see that,

The scatter plot of option A and D graphs have a line that is a line of best fit for the data points.

Thus,

Area of square(A)= l^2

or, 25=x^2

or, √25 = x

or, 5cm = x

Step-by-step explanation:

Given, that the area of the square = 25cm^2

area of square = (side)^2

25 = x^2

x = √25

As the side of the curved line on the right increases in the x direction (input) the curved lines gets greater t words the left side . This means the output decreases.

answer:

D. As the input increases, the output decreases for all values of x.

Option A

It's a parabola having vertex (-1,-5)

As we can see the graph .

The curve first decreases until it reaches the vertex (-1,-5) then it increases on increase in x

As parabola is opening upwards Vertex is minimum

So option A is correct

Answer:

B

Step-by-step explanation:

Step-by-step explanation:

any quadratic equation has the form

y = ax² + bx + c

so, we can see in our case

a = 1

b = 8

c = 7

the x value of the vertex is indeed camcorders by

x = -b/(2a) = -8/2 = -4

the corresponding y we get then

y = (-4)² + 8×-4 + 7 = 16 - 32 + 7 = -9

the vertex = (-4, -9).

the y- intercept is simply the point with x = 0 (and the corresponding y value).

which is c, because

y = 0² + 8×0 + 7 = 7

the y-intercept = (0, 7)

The total amount of the outstanding loan that the bank loaned at 10% interest rate is $4,000.

a + b = $10,000 equation 1

0.1a + 0.07b = 820 equation 2

Where:

Multiply equation 1 by 0.07

0.07a + 0.07b = 700 equation 3

Subract equation 3 from equation 2

0.03a = 120

Divide both sides of the equation by 0.03

a = 120 / 0.03

a = $4000

We know QS is parallel to RT, so that will be the first one. We also know that r is congruent to s, so add that if possible

Next, we have to use the alt. int. angles are congruent theorem, so we can say that angle QTR and angle SOT are congruent due to this rule.

Next we have to use reflexive property, and the only thing that fits is the transversal intersecting the parallel lines. So we can say that QT is congruent to TQ.

Then we can say that triangle SQT and triangle ROT are congruent due to SAS.

Finally, we can say angle QTS is congruent to angle TQR because of corresp. parts of congruent triangles are congruent(CPCTC for short)

MN goes through

Slope:-

Slope of perpendicular line:-

Passes through k(3,-3)

Equation in point slope form

Check one by one

Yes option B is correct

Answer:

(2, 2)

Step-by-step explanation:

First find the slope of the line MN, using the two given points:

[tex]\sf let\:(x_1,y_1)=(2,3)[/tex]

[tex]\sf let\:(x_2,y_2)=(-3,2)[/tex]

[tex]\implies \sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-3}{-3-2}=\dfrac15[/tex]

If two lines are perpendicular to each other, the product of their slopes will be -1.

Therefore, the slope (m) of the line perpendicular to MN is:

[tex]\implies \dfrac15 \times m=-1[/tex]

[tex]\implies m=-5[/tex]

Using the point-slope form of the linear equation with point K (3, -3), we can construct the linear equation of the line perpendicular to MN:

[tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-(-3)=-5(x-3)[/tex]

[tex]\implies \sf y=-5x+12[/tex]

Now we have the equation of the line perpendicular to MN, we can input the x-values of the solution options to see which once is correct:

[tex]x=0\implies \sf y=-5(0)+12=12\implies (0,12)[/tex]

[tex]x=2\implies \sf y=-5(2)+12=2\implies (2,2)[/tex]

[tex]x=4\implies \sf y=-5(4)+12=12\implies (4,-8)[/tex]

[tex]x=5\implies \sf y=-5(5)+12=-13\implies (5,-13)[/tex]

Therefore, the point that is on the line that is perpendicular to MN and passes through point K is (2, 2)
