Step-by-step explanation:

The domain of the relation is {1, 2, 3, 4, 5} and the range of the relation is {0.75, 1.50, 2.25, 3.00, 3.75}

As per the question statement, the total cost for cars entering President George Bush Turnpike at Beltline Road is related to the number of cars entering the turnpike at Beltline Road. The costs of different numbers of cars entering the turnpike at Beltline Road are as follows: 1 car, $0.75; 2 cars, $1.50; 3 cars, $2.25; 4 cars, $3.00; 5 cars, $3.75.

Before solving the question we need to know what is domain and range basically.

Ordered pair : {(1,0.750 , (2,1.50) , (3,2.25) , (4,3.00) , (5,3.75)}

Domain is the set which consists of all the first elements of all the ordered pair of the given relation, therefore Domain is {1, 2, 3, 4, 5}.

Range is the set which consists of all the second elements of all the ordered pair of the given relation, therefore Range is {0.75,1.50,2.25,3.00,3.75}

And yes, the given relation is also a function because as the number of cars increases the total cost is also increasing but gradually with a constant value.

Answer:

0.0035

Step-by-step explanation:

In front of the decimal point is the ones place. After that is the tenths place, hundredths place, and then thousandths place.

Answer is the coordinates of endpoint F(6, 4).

In geometry, the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment.

let coordinate of F is (x,y).

4= (x + 2)/2

8= x +2

x = 6

6= (y +8)/2

12 = y + 8

y = 4

Answer:

[tex]y_e = -\frac34x + 5[/tex]

Step-by-step explanation:

The equation of a line, if given its slope and one point that it passes through, is given by the formula [tex]y - y_1 = m(x - x_1)[/tex].

Therefore, we can substitute [tex]m = -\frac34[/tex], [tex]x_1 = 8[/tex] and [tex]y_1 = -1[/tex] into the formula above.

[tex]y - (-1) = -\frac34(x - 8)\\\\\to y + 1 = -\frac34x + 6\\\\\to y = -\frac34x + 5[/tex]

Let x be the number of weeks passed.

Denote by J(x) the money with Joe.

Denote by B(x) the money with his brother.

Denote by s(x) the money they raised together.

[tex]J(x)=assets+money \: raised \\ J(x)=170 + 20x[/tex]

If we want Joe's brother to have more money at the x week, then B(x) has to be greater than J(x)

[tex]B(x) > J(x) \\ 80 + 40x > 170 + 20x \\ 40x - 20x > 170 - 80 \\ 20x > 90 \\ x > \frac{90}{20} \\ x > 4.5 \: \: \: so \: \: \: x = 5[/tex]

The simplest form of the expression [tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex] is [tex]\frac{1}{x}[/tex].

The simplest form of a fraction is one with a reasonably prime denominator and numerator. It indicates that, except for 1, there is no common factor between the fraction's numerator (upper portion or top) and denominator (lower part or bottom).

A fraction is a number that has been expressed as a quotient by dividing the numerator by the denominator. Both are integers in a simple fraction. In a complex fraction, a fraction can be found in either the numerator or the denominator.

An expression is made up of a number, a variable, or a combination of a number, a variable, and operation symbols. Two expressions joined by an equal sign form an equation.

Consider the expression,

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex]

Now we know,

[tex]x^{-1}=\frac{1}{x}[/tex]

Therefore,

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{\frac{x^4}{x^{-1}} })^{\frac{1}{5} }[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{x^{-1}}{x^4})^{\frac{1}{5}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{x \times x^4})^{\frac{1}{5}[/tex]

Using the exponential rule,

[tex]n^{b} \times n^{a} = n^{a+b}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = (\frac{1}{x^{5}} )^{\frac{1}{5}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = \frac{1}{x^{5 \times \frac{1}{5} }}[/tex]

The area of the isosceles triangle is 60 square units

The formula for area of an isosceles triangle is expressed as;

Area = bh/2

Where;

Now, let's find the height of the triangle.

Using Pythagorean theorem, we have;

13^2 = 5^2 + h^2

Find the square

169 = 25 + h^2

collect like terms

169- 25 = h^2

h^2 = 144

Find the square root of both sides

h =√ 144

h = 12

Let's find the area

Area = 10 × 12/2

Area = 120/2

Area = 60 square units.

1/2x + 5

Step-by-step explanation:

The value of K is 2 so that the point A lies on the line given by the equation A (2,1), 3x+ky=8.

Given: Equation is 3x+ky=8

Points A (2,1)

We need to determine the value for K

3x+ky=8   — 1 (Take as equation 1)

Substitute the points in equation 1

So, we take x = 2 and y = 1

3(2) +k (1) = 8

6+k = 8

k = 8 - 6

k = 2

When graphing points on a coordinate plane, it is often helpful to find the value of k that makes the point lie on a line. For this problem, k = 2 so that A (2,1), 3x+ky=8.

Hence, the value of K is 2 so that the point A lies on the line given by the

equation A (2,1), 3x+ky=8.

Domain of f + g ( x) = R and f - g ( x) = R

Given :

F(x) = 2x^2 + 8  and g(x) = x-3

From this, we get to know that f(x) and g(x) assume real values for all values of x.

Hence, domain (f)= Real(R) and domain (g)= real ( R ) .

Therefore D (f) and D(g) are Real Number

Now,

A >   (f + g ) : R ----> R is given by (f + g) (x)

       = f(x) + g(x) = 2x^2 + 8 + x- 3

                             = 2x^2  + x + 5

Hence, domain ( f + g ) = Real ( R )

B >    (f – g) : R---> R is given by ( f-g ) (x)

= f(x) – g(x)  = 2x^2 + 8 – ( x – 3)

                    = 2x^2 -x + 11

Hence, domain ( f - g ) = Real ( R )  .

Answer: they will get 27 each and their will be 13 left over

Step-by-step explanation:

The difference between the measures of center is equal to the measure of variation.

The IQR of the given box plot:

Q1 = 10

Q3 = 18

IQR = Q3 − Q1 = 18 − 10 = 8

Median = 15

Q1 = 4

Q3 = 12

IQR = Q3 − Q1 = 12 − 4 = 8

The difference between the measures of center as a multiple of the measure of variation:

Median of first data set - median of the second data set

IQR = 15 − 7 / 8

= 1

and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.

According to the question we have been given the growth that is +500%. Since there is plus sign therefore it is a growth factor.

Thus, r = + 5
