Answer:

Triangular inequality:  Length of third side must be less than the sum of the lengths of the other 2 sides.

x < 18 + 29

x < 47

so Maximum length of third side is 46 units.

Also 29 < 18 + x

x > 11    so minimum length = 12

Difference  = 46-11 = 35

x=0 is an extraneous solution of the equation and x = 8 is not an extraneous solution of the equation.

√(3x+1) - √(x+1) = 2

√(3x+1) = 2 + √(x+1)

Squaring both the sides of the equation

(√(3x+1))² = (2 + √(x+1))²

3x + 1 = (2)² + (√(x+1))² + 2(2) (√(x+1))

3x + 1 = 4 + x + 1 + 4(√(x+1))

3x + 1 = 5 + x + 4(√(x+1))

2x - 4 = 4(√(x+1))

Squaring again on both the side of the equation, we get

(2x - 4)² = (4(√(x+1))²

4x² + 16 - 16x = 16x + 16

4x² - 32x = 0

4x(x - 8) = 0

4x = 0 and x - 8 = 0

x = 0 and 8

Check for Extraneous Solution by keeping value of x in the original equation √(3x+1) - √(x+1) = 2

Let x=0

√(3(0)+1) - √(0+1) = 2

0 ≠ 2

LHS ≠ RHS

x = 0 is an extraneous solution of the equation

Let x=8

√(3(8)+1) - √(8+1) = 2

✓25 - ✓9 = 2

5 - 3 = 2

2 = 2

LHS = RHS

∴ x=8 is not an extraneous solution of the equation.

Answer:

a) 6 hours

b) 12 hours

c) 36 hours

Step-by-step explanation:

let hours taken to mow lawns = x

baby sit hours = 2x

walk dogs hours = 3(2x) = 6x

x+2x+6x = 54

thus, x = 6

the extraneous solution for the equation √ (x + 3) - 1 = x is x = 1 or x = - 2.

We are given an equation:

√ (x + 3) - 1 = x

√ (x + 3) = x + 1

Raise both sides to the power 2, we get that:

x + 3 = x² + 1 + 2 x

x² + 2 x - x + 1 - 3 = 0

x² + x - 2 = 0

x² + 2 x - x - 2 = 0

x ( x + 2) - 1 ( x + 2) = 0

(x - 1)(x + 2) = 0

x = 1 or x = - 2.

Therefore, we get that, the extraneous solution for the equation √ (x + 3) - 1 = x is x = 1 or x = - 2.

If the expression is log₂9-log₂3, then it will look like [tex]log_{2}3[/tex] in single logarithm.

Given that the expression is log₂9-log₂3.

We have to give the single logarithm for the given expression.

The quotient rule for logarithms tells us that the logarithm of a quotient is equal to a difference of logarithms. Just as with the product rule we also can use the inverse property to derive the quotient rule. The quotient property basically says that log (m/n)=log m-log n.

The expression is log₂9-log₂3.

log₂9-log₂3=[tex]log_{2}[/tex](9/3)

The exponential function for the value of car is V = 25,000 × e^( r × T) and the value of the car after 5 years is $ 1109.26.

The original value of a car is $25,000.

The value of the car after one year is $21,250.

Let V be the value of the car after T years.

Let the rate at which the value of the car increase be r.

From, [tex]\[ A = Pe^{r \times T} \][/tex]

Then,

[tex]\[ V = 25,000 \times e^{ r \times T } \][/tex]

The value of the car after one year is $21,250.

[tex]\[ 21,250 = 25000 \times e^{ r \times T } \][/tex]

Divide both sides by 25000

[tex]\frac{21250}{25000} = e^{1 \times r }[/tex]

Now, taking the log of both sides

[tex]\[ \ln (21250/25000) =\ln e^{1 \times r} \][/tex]

By the property of logarithm,

[tex]\ln e^{(1 \times r)} = r[/tex]

Therefore,

㏑(21250/25000) = r

Now, the value of the car after 5 years will be:

[tex]\[ V = 25,000 \times e^{ r \times T} \]\\\\[/tex]

[tex]\[ V = 25000 \times e^{ \ln (\frac{21250}{25000} ) \times 5 } \][/tex]

Answer: Solution is t = 905/8

Step-by-step explanation:

Given data,

         ttt:-\dfrac{7}{4}=\dfrac{2}{5}t− 47 = 52​ t

We can write,

              - 7/4 = (2/5) t - 47

Rearrange variables to the left side of the equation

               - (2/5) t = - 47 + 7/4

Find common denominator and write the numerators above common denominator

                 - (2/5) t = ( -188 + 7 ) / 4

calculate the sum or difference

                   - (2/5) t = -181/4

Divide both sides of the equation by the coefficient of variable

                      t = (-181/4) x (-5/2)

Determining the sign for multiplication or division

                       t = 181/4 x 5/2

Write as a single fraction

                          t = ( 181 x 5 ) / ( 4 x 2 )

Calculate the product or quotient

The required value of z using given conditions and functions is 7.92.

What is a function?

A function is defined as an expression or rule that specifies the relationship between two variables or objects, out of which one is dependent and the other is an independent variable. The image of each and every element is unique.

Calculation for the value of z

Given value of z = 1.5, x = 9, y = 4

Consider z as a function varying directly with x and inversely with y i.e.

z = kx / y        —-- 1

Putting the values of x, y, z, we get,

1.5 = k × 9 / 4

6 = 9 × k

k  = 6 / 9

k = 2 / 3 = 0.66

Now, calculating z for x = 6, k = 0.66 and y = 0.5, using function,

z = (0.66 × 6) / 0.5

= 3.96 / 0.5

= 7.92

Hence, the required value of z = 7.92.

The answers will be :

b. The midpoint of the line segment will be ( -2 , -2 ).

c. The equation of line passing through points Y and Z will be 4y + x - 10 = 0

What is slope of a line segment ?

The ratio of the difference in y-coordinates over the equivalent x-coordinates between two different locations on a line.

It is given that a line segment has endpoints of Y(2,-3) and Z(-6,-1).

Let's solve the given parts based on the above data.

a.

The length of the line segment will be given by :

YZ = [tex]\sqrt({x_{2} - x_{1})^2 + (y_{2}- y_{1})^2}[/tex]

YZ = √ [( -6 -(2)]^2 + [ -1 - (-3)]^2}

YZ = √ (-8)² + 2²)

YZ = √68

YZ = 8.24 units

b.

The midpoint (say M) of the line segment will be given by :

M = ( [tex]\frac{x_{1} + x_{2} }{2} , \frac{y_{1} + y_{2} }{2}[/tex])

M = [(2-6)/2 , (-3-1)/2]

M = ( -2 , -2 )

c.

And the equation of line passing through points Y and Z will be :

[tex]y_{2} - y_{1}[/tex] = m ( [tex]x_{2} - x_{1}[/tex] )

Let's calculate value of slope (m) firstly which will be :

m =([tex]y_{2} - y_{1}[/tex]) / ( [tex]x_{2} - x_{1}[/tex] )

m = ( -1 + 3 ) / (-6 - 2)

m = 2 / -8

m = -1 / 4

or

m = -0.25

Using the value of slope (m) : we get the equation of line as :

[tex]y - y_{1}[/tex] = - 0.25 ( [tex]x - x_{1}[/tex] )

or

(y + 3) = - 0.25 ( x - 2)

y + 3 = -0.25 x + 0.50

or

y + 0.25 x - 2.5 = 0

If we multiply by 4 throughout the equation ; then the equation of line can also be written as :

4y + x - 10 = 0

Therefore the answers will be :

a. The length of the line segment will be equal to 8.24 units.

b. The midpoint of the line segment will be ( -2 , -2 ).

c. The equation of line passing through points Y and Z will be 4y + x - 10 = 0

A number line plot is a graph that displays the frequency a number occurs in a set of data. Dot plot is another name for a number line plot.

The number line is a one-dimensional graph that can display all of the rational numbers (whole numbers, integers, and rational numbers).

The numbers we use for counting, or enumerating items, are the natural numbers: 1, 2, 3, 4, 5, and so on. We describe them in set notation as {1,2,3,...} where the ellipsis (…) indicates that the numbers continue to infinity. The natural numbers are, of course, also called the counting numbers. Any time we enumerate the members of a team, count the coins in a collection, or tally the trees in a grove, we are using the set of natural numbers. The set of whole numbers is the set of natural numbers plus zero , 0,1,2,3,...

The set of integers adds the opposites of the natural numbers to the set of whole numbers: −3,−2,−1,0,1,2,3,

It is useful to note that the set of integers is made up of three distinct subsets: negative integers, zero, and positive integers. In this sense, the positive integers are just the natural numbers.
