Answer:

19 and 12

Step-by-step explanation:

The rule is y = 2x - 1

If x = 10, y = 19 because 20 - 1 = 19

If y = 23, x = 12 because 24 / 2 = 12

The quadratic equation x² - 12x + 6 = 0 is factorized and the solution to the equations are x = 6 ± √30

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² - 12x + 6 = 0   be equation (1)

Now , to calculate the solution of x ,

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = 12 ± √ ( 144 ) - ( 24 ) / 2

x = 12 ± 2√30 / 2

x = 6 ± √30

Hence , the solutions to the equation are x = 6 + √30 or x = 6 - √30

The measure of arc FB is 68 degrees.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

In the given circle BE is a semicircle

The measure of arc FC is 104 degrees.

We need to find the measure of arc FB

From the figure the measure of arc BC is 36 degrees

FC=FB+BC

104=36+FB

Substitute 36 from both sides

104-36=FB

68 degrees =FB

To find first-order linear differential equations solution, we have to derive the general form or representation of the solution.

With the help of the steps shown below, we can learn how to solve the first-order differential equation.

1. Reorder the terms in the given equation so that they have the form [tex]$\frac{dy}{dx}+Py=Q[/tex] where P and Q are constants or functions of the independent variable x only.

2. Integrate P (obtained in step 1) with respect to x and then put this integral as a power of e to determine the integrating factor.

[tex]$e^{\int P d x}[/tex] = IF

3. The linear first-order differential equation's two sides should be multiplied by the IF.

4. The L.H.S of the equation is always a derivative of [tex]$y \times M(x)$[/tex] i.e. L.H.S [tex]$= \frac{d(y \times I . F)}{dx}[/tex]

[tex]$d(y \times I . F) d x=Q \times I . F$[/tex]

5. In order to arrive at the solution, we simply integrate both sides with respect to x in the last step.

Therefore [tex]y \times I . F=\int Q \times I . F d x+C$,[/tex]

where C is some arbitrary constant

Similarly, we can also solve the other form of linear first-order differential equation [tex]$\frac{dy}{dx}+Py=Q[/tex] using the same steps.

P and Q are y's functions in this manner. We determine the solution, which will be, by using the integrating factor (I.F), which is

The correct statement is -

company {R} charges less money for 1 hour of service compared to company {P}.

Given is that Limousine Company {P} charges a rental fee plus an additional charge per hour. The equation {y} = 50 + 30x shows the total cost. The cost to rent a limousine from Company {R} is shown below in the table as -

Time :   1       2        3         4       5

Cost : $100  $125  $150  $175  $200

We can write the unit charge for company {P} as -

{r₁} = $30

We can write the unit charge for company {R} can be calculated as -

{r₂} = (125 - 100)/(2 - 1)

{r₂} = $25

We can conclude -

company {R} charges less money for 1 hour of service compared to company {P}.

Answer: I would say B.

Step-by-step explanation: why not pick B…..

Hope this help^^

Answer: Let's use x to represent the cost of each topping. Then, the cost of a pizza with t toppings can be expressed as:

C = x * t + 15

We know that Kevin's pizza with 3 toppings cost $15.74, so we can write an equation using this information:

15.74 = 3x + 15

Solving for x, we get:

x = (15.74 - 15) / 3 = 0.74

So, each topping costs $0.74. Now we can use the information about Brian's pizza to check our answer:

14.49 = 2x + 15

Substituting x = 0.74, we get:

14.49 = 2 * 0.74 + 15

Which simplifies to:

14.49 = 1.48 + 15

This confirms that x = 0.74 is the correct cost for each topping. Therefore, the equation for the cost of a pizza as a function of the toppings ordered is:

C = 0.74t + 15

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number.

The standard form of a polynomial is expressed by writing the highest degree of terms first then the next degree and so on.

Hence, let's write the polynomial in standard form as follows:

6x³ - 8x⁴ + 5x + 12x² - 9

The constant of variation for this relation is 10.

If y varies directly as x, we can write it as y = kx, where k is the constant of variation. This constant represents the relationship between x and y, and it determines how much y changes for a given change in x.

To find the constant of variation, we need to know the value of y and x. In this case, we are told that y is 12 when x is 1.2. Using this information, we can solve for k by dividing both sides of the equation by x:

y = kx

12 = k * 1.2

12 / 1.2 = k

k = 10

So the constant of variation is 10. This means that for every change of 1 in x, y will change by 10. In other words, if x increases by 1, y will increase by 10, and if x decreases by 1, y will decrease by 10.

The standard form of the equation of the parabola with focus (0, 7) and the vertex at the origin is y = 1/28 x² + 7

A parabola is a symmetrical U-shaped curve that is defined by the set of all points that are equidistant to a fixed point, called the focus, and a straight line called the directrix. In a parabolic equation, the focus and the vertex are important points that determine the shape and position of the parabola.

In the case of the parabola with focus (0, 7) and the vertex at the origin (0,0), we can use the standard form of the equation of a parabola to write its equation. The standard form of a parabola is given by:

y = a(x - h)² + k

Where (h,k) is the vertex of the parabola and a is the coefficient that determines the direction and width of the parabola. To write the equation of this parabola, we need to find the value of a.

Since the focus is (0, 7) and the vertex is (0,0), we can use the formula:

a = 1/(4f)

Where f is the distance from the vertex to the focus. In this case, f = 7. Therefore, a = 1/(4 * 7) = 1/28.

Finally, we can substitute these values into the standard form to get the equation of the parabola:

y = 1/28 x² + 7

The radius and center of the translated circle are,

Radius = 7 units

Center = (10, - 2)

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

The equation of circle is,

x² + y² - 18x + 8y + 48 = 0

Now, We can simplify the equation as;

x² + y² - 18x + 8y + 48 = 0

x² - 18x + 81 - 81 + y² + 8y + 16 - 16 + 48 = 0

(x - 9)² + (y + 4)² = 49

(x - 9)² + (y + 4)² = 7²

Hence, The radius of circle = 7

And, Center = (9, - 4)

Let the center of circle after translated one unit right and two units down is, (h', k')

Hence, We get;

h' = 9 + 1 = 10

k' = - 4 + 2 = - 2

Thus, The equation of the translated circle is,

(x - 10)² + (y - (- 2))² = 7

Hence, the radius and center of the translated circle are,

Radius = 7 units

The age of the mammal hide is 3567 years

Radioactivity can be used to determine the age of rocks, minerals, and fossils through a method called radiometric dating. This method is based on the principle that certain isotopes of elements decay at a known rate over time, producing new isotopes. By measuring the relative amounts of the original parent isotope and the newly formed daughter isotope, scientists can determine how much time has passed since the rock, mineral, or fossil was formed.

0.70 = 1 * e^-0.0001t

Take the logarithm of both sides:
