The domain of the function is [1, ∞) and the range of the function is [0,∞).

Domain and range:

The domain and range of a function are  refers the set of all the inputs and outputs a function can give respectively.

Basically, domain takes all the possible input values from the set of real numbers whereas the range takes all the output values of the function.

Given,

Here we have the function

y = √x - 1

Now, here we need to find the domain and range of the function.

The given function is rewritten as,

√x - 1 > 0

Square both sides then we get,

x - 1 > 0

Add 1 on both sides then we get,

x > 1

Therefore, the domain is [1, ∞).

Similarly, let us consider, y ≥ 0

Therefore, the range is [0,∞).

The number of people that can attend Jordan's party is 50 people.

The equation that represents the total amount that would be spent at the party would be a linear equation. A linear equation increases at a constant rate.

The form of the linear equation would be:

Total amount = rental fee + (charge per hour of the Dynamic DJ x number of hours he plays) + (cost per person of Roscoe's rentals x number of people)

$800 = $400 + ($50 x 4) + ($4 x p)

$800 = $400 + $200 + $4p

$800 = $600 + $4p

Given: Given the function: f(x) = (x − 3)(x + 7)(x − 1)

Required: its f-intercept and its x-intercepts.

Explanation:

For f-intercept, put x = 0

So the f-intercept is (0,21).

For x-intercepts, put f(x) = 0

So x-intercepts are (3,0),(-7,0) and (1,0).

Final Answer:

f-intercept: (0,21)

x-intercept: (3,0),(-7,0),(1,0).

The time taken by Town A to Town B will be 3 hours.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

Given that at 30 mph a trip from Town A to Town B takes 6 hours.

The time taken will be calculated as,

Total distance = 30 x 6 = 180 meters

Speed = 30 x 2 = 60 mph

The time,

T = 180 / 60= 3 hours

Therefore, the time taken by Town A to Town B will be 3 hours.

A percent discount of 30%

Explanation:

Since $129 represent 100% of the price, then the new price $90.30 represent 70 %

129 * 100 / 90.30 = 70 %

Since from the 100% of the price, it went to 70% of it, there was a discount of 30%

100 - 70 = 30%

Given multiplication:

[tex]3 \dfrac{1}{5} \times 2 \dfrac{5}{8}[/tex]

Convert the mixed numbers into improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:

[tex]\implies \dfrac{3 \times 5+1}{5} \times \dfrac{2 \times 8+5}{8}[/tex]

[tex]\implies \dfrac{15+1}{5} \times \dfrac{16+5}{8}[/tex]

[tex]\implies \dfrac{16}{5} \times \dfrac{21}{8}[/tex]

[tex]\textsf{Apply\;the\;fraction\;rule} \quad \dfrac{a}{b} \times \dfrac{c}{d}=\dfrac{ac}{bd}:[/tex]

[tex]\implies \dfrac{16 \times 21}{5 \times 8}[/tex]

[tex]\implies \dfrac{336}{40}[/tex]

Reduce the fraction by dividing the numerator and denominator by the common factor of 8:

[tex]\implies \dfrac{336 \div 8}{40 \div 8}[/tex]

[tex]\implies \dfrac{42}{5}[/tex]

Divide the numerator by the denominator:

[tex]\implies 42 \div 5=8\;\textsf{remainder}\;2[/tex]

The mixed number answer is the whole number and the remainder divided by the denominator:

[tex]\implies 8 \dfrac{2}{5}[/tex]

Step-by-step explanation:

when you want to start solving it you will do 16 over 5 * 21/8equals 8 whole number 2/5

it will give you 336 all over 40 if you divide by 8 you will get 42/5 which is 8 whole number 2/5

Answer:

Step-by-step explanation:

You want to find the equivalent expressions among ...

The relevant rule of exponents is ...

  a^b = (1/a)^-b

Expressions with the same base and different exponents will not be equivalent. (A≠B).

Expressions with different bases and the same exponent will not be equivalent. (A≠C).

A variable in the base cannot replace a variable in the exponent. (A≠D).

The rule of exponents tells us replacing the base by its reciprocal and negating the exponent will result in an equivalent expression. (B=C).

The equivalent expressions are 4^(-3x^2) and (1/4)^(3x^2).

Step-by-step explanation:

The area of the smaller rectangle is 108 inches².

The area of a rectangle is calculated to determine the area occupied by the rectangle within its boundary. A rectangle's area (A) is the product of its length 'a' and width or breadth 'b'. As a result, the Area of the Rectangle = (a × b) square units.

Given the dimensions of the smaller rectangle:

Length = 12 inches

Width = x inches

Given the dimensions of the larger rectangle:

Length = 20 inches

Width = 15 inches

To find the value of x we use proportion,

[tex]\frac{12}{x} = \frac{20}{15}[/tex]

Cross-multiplying, we get

12 × 15 = 20x

x = 180/20 = 9

Hence, the width of the smaller rectangle is 9 inches.

Area of the smaller rectangle = length × width

                                                = 12 × 9

                                                = 108 inches²

The value of x is 10 and the length of SU is 50.

Here SU is the line and T is the mid-point of the line

So from this we have

SU = ST + TU

ST = TU

SU = 2ST = 2TU

ST = 3x - 5 and TU = 2x + 5

As ST = TU

3x - 5 = 2x + 5

x = 10

SU = 2ST

     = 2( 3x - 5)

     = 2( 3 × 10 - 5)

The polynomial having the above quantities is expressed as x³ - 2x² - 5x + 10 = 0

The above situations will form a Cubic polynomial. A Cubic polynomial function may be defined as an expression which can be written in the form of ax³ + bx² + cx + d = 0 where a, b, c and d are coefficients and x is the independent variable. Since, the polynomial should have real coefficients so its multiplicity will be equal to 1. Now, the roots of the polynomial are given as 2 and √5. Since, square roots always occur in pair so the polynomial will have -√5 as its root. Now, the polynomial formed will be

(x - 2) (x - √5) (x + √5) = 0

(x - 2) (x² - 5) = 0

x³ - 5x - 2x² + 10 = 0
