Answer:

the daily fee is 37 and the mileage charge is .24 per mile.

Step-by-step explanation:

256 = 450x + 4b

159 = 200x + 3b

Multiple the top equations by -3 all the way through the bottom equations by 4 all the way  through then add the equation together.

-768 = -1350x -12b

636 = 800x + 12b

-132 = -550x  Divide both sides by -550

.24 = x  This is the charge per mile.

Plug in .24 for x into either of the original 2 equations to solve for b which is the daily fee.

256 = 450(.24) = 4b

256 = 108 + 4b  Subtract 108 from both sides

148 = 4b  Divide both sides by 4

37 = b  This is the daily fee.

What is LCM?

Least Common Multiple is the meaning of the acronym LCM. The smallest number that both numbers can divide by is known as the least common multiple (LCM) of two numbers. It can also be computed for two or more different numbers. There are numerous ways to calculate the LCM of a given collection of numbers. Utilizing the prime factorization of each number and then calculating the product of the highest powers of the common prime factors yields the LCM of two integers in a short amount of time.

(16-p)/[ (p+4)(p-6) ] + 2/ (p+4)

Take LCM = (p+4)(p-6)

= [ 16-p + 2(p-6) ] / [  (p+4)(p-6)  ]

=  [ 16-p + 2p-12) ] / [  (p+4)(p-6)  ]

= ( p +4 ) / [  (p+4)(p-6)  ]

= 1/(p-6)

The probability that a child chosen at random from the school arrives by car is the total of the column Car 74%.

Describe probability using an example?

By dividing the number of preferable possibilities by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained.

                           The most basic illustration is a coin toss. There are only two outcomes that can occur when you flip a coin: either heads or tails.

You can build a two-way relative frequency table to represent the data:

These are the columns and rows:

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the personal best time of Dean be = A

Now , the value of A = 3 hours 14 minutes 45 seconds

And ,

The time taken by Dean to complete 1 km = 9 minutes 30 seconds

Now , the total distance of the race lap = 20 km

So , the equation will be

Total time taken by Dean to complete 20 km race B = 20 x time taken by Dean to complete 1 km

Substituting the values in the equation , we get

Total time taken by Dean to complete 20 km race = 20 x 9 minutes 30 seconds

Total time taken by Dean to complete 20 km race = 20 x 9 minutes + 20 x 30 seconds

Total time taken by Dean to complete 20 km race = 180 minutes + 600 seconds

1 hour = 60 minutes

1 minute = 60 seconds

180 minutes = 3 hours

600 seconds = 10 minutes

So , the equation is

Total time taken by Dean to complete 20 km race B = 3 hours 10 minutes

So , the value of B < value of A

Therefore , the Dean will beat his personal best time and the race is completed in 3 hours 10 minutes

Hence , Dean will take a total time of 3 hours and 10 minutes to complete the race and will beat his personal best time

An equation of the parabola with focus (1, 6) and directrix y = 1 is: C. y = 1/10(x²) - 1/5(x) + 18/5

Mathematically, the standard equation of the directrix lines for any parabola is given by:

y = a(x - h)² + 2.

Where:

Since the directrix is horizontal, the axis of symmetry would be vertical. Therefore, the equation of this parabola would be modeled by this standard mathematical expression;

(x - h)² = 4p(y - k)

Where:

h = 1

In Mathematics, the focus for either a right or left parabola is modeled by this mathematical expression (h + p, k) while its directrix is modeled by this mathematical expression x = h - p;

k + p = 6

k - p = 1

Solving the set of linear equations simultaneously, we have:

2k = 7

k = 7/2

For the value of p, we have;

p = 6 - k

p = 6 - 7/2

p = 5/2

Substituting the given parameters into the formula, we have;

(x - 1)² = 4(5/2)(y - 7/2)

x² - 2x + 1 = 10(y - 7/2)

x² - 2x + 1 = 10y - 35

10y = x² - 2x + 1 + 35

10y = x² - 2x + 36

y = (x² - 2x + 36)/10

y = x²/10 - x/5 + 18/5

The cost from company A and company B will be the same at 40 square feet of countertop

Given that:

Company A will sell Mikayla a countertop according to the given

graph, which includes a $1, 000 installation fee.

Company B will sell a countertop according to the values given in the

table, which includes an $800 installation fee and a constant rate of change

With this information, you can make cost function for both Company A and Company B

Company A

A linear function is of the form y = mx + c

where c is the y-intercept (starting point) and m is the slope (rate)

c = 1000  (from the graph)

m = 1150-1000 / 10-0  (By using the 2 points on the graph: m = y2-y1/x2-x1)

m = 15

y = mx + c

y = 15x+1000

Company B

c = 800  (given)

m = 1100-1000 / 15-10  (From table)

m = 100/5 = 20

y = mx + c

y = 20x+800

Equate the two cost functions and solve for x:

20x+800 = 15x+1000

20x-15x = 1000-800

5x = 200

x = 200/5

x = 40 square feet

Therefore, at 40 square feet of countertop, the cost from each company will be the same

geologists unearth a sample of zircon that appears to be a closed system. they find 0.686 micro gram of 206 Pb for 1.000 micro gram of 238U present. approximately  3.7973 × 10⁹ years old is the sample.

The reciprocal of the time period during which the number of atoms in the radioactive element drops to almost A. 50% of its initial number is the decay constant.

According to the radioactive decay law, a nucleus's likelihood of decaying is a constant that is independent of time.

t1/2 of U₂₃₈ is 4.5 × 10⁹ years

moles of U₂₃₈ : (1 × 10⁻⁶ / 238) moles

moles of Pb₂₀₆ : (0.686 × 10⁻⁶ / 206) moles

Now, U₂₃₈ → Pb₂₀₆

As Pb₂₀₆ comes from U₂₃₈ hence,

moles of  U₂₃₈ decayed = moles of  Pb₂₀₆

                                        = (0.686 × 10⁻⁶ / 206) moles

Therefore, initial moles of U₂₃₈:

N₀ = [(1 × 10⁻⁶ / 238) + (0.686 × 10⁻⁶ / 206)] moles

and N = (1 × 10⁻⁶ / 238) moles

Now, λ (decay constant) = 0.693 / (t1/2)

                                        = 0.693 / ( 4.5 × 10⁹ years)

So,

t = 2.303 / λ × log (N₀ / N)

t = 2.303 / [0.693 / ( 4.5 × 10⁹ years)] × log [1 + (0.686/206)/(1/238)]

t = 14.95 × 10⁹ × 0.254

t = 3.7973 × 10⁹ years.

Thus, the sample is: 3.7973 × 10⁹ years old.

The minimum value of the function y = 2(x - 3)² - 4 is -4. Domain of the function is set of all real numbers and the range is all real numbers ≥ -4.

Domain of a function y = f(x) is the set of all the values of x where the function is defined.

The range of the function is the set of all values of the function on the defined domain.

The given function is,

y = 2(x - 3)² - 4

y = 2(x² - 6x +9) - 4

y = 2x² - 12x + 14

This is a quadratic function and the graph of the function will be a parabola.

The parabola is directed upwards if the coefficient of x² in a quadratic equation is positive and so will be having a minimum value.

The parabola is directed downwards if the coefficient of x² is negative and so will be having the maximum value for the function.

Here, coefficient of x² = 2, is positive.

So there will be a minimum value.

The value of [tex]\frac{-b}{2a}[/tex] in the quadratic equation ax² + bx + c, is the x value of the vertex of the parabola.

x = - (-12) / (2 × 2) = 3

∴ Minimum value, y = 2 (3 - 3)² - 4 = -4

Domain of the function will be the set of all real numbers because the function is defined for all real numbers.

The range will be all real numbers ≥ -4, because any values of x in the function does not make the value of the function less than -4.

Hence the minimum value of the function is -4 and the domain and the range of the function is set of all real numbers and all real numbers ≥ -4 respectively.
