The explicit rule for the arithmetic sequence that represents the number of miles that Abby will run in week n is:

[tex]a_n = 15 + 2n[/tex]

Using this rule, it is found that she will run 39 miles during her 12th week of training.

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term.

On the first week, she runs 15 miles, and for each subsequent week this amount increases by 2 miles, hence the first term and the common difference are given as follows:

[tex]a_1 = 15, d = 2[/tex]

The explicit rule for the arithmetic sequence that represents the number of miles that Abby will run in week n is:

[tex]a_n = 15 + 2n[/tex]

During the 12th week, the number of miles that she will run is found as follows:

[tex]a_{12} = 15 + 2(12) = 39[/tex]

Answer:

4.5 miles

Step-by-step explanation:

We don't really need an equation for this, as we know what one half of three is - it is 1.5.  So we just add 3 and 1.5 to get the sum.

Step-by-step explanation:

The formula for finding the length between two points is as follows:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

All we have to do is plug in our values and solve:
[tex]D=\sqrt{(-4-(-1))^2+(-4-2)^2}\\D=\sqrt{(-3)^2+(-6)^2}\\D=\sqrt{9+36}\\D=\sqrt{45}\\ D=6.71[/tex]

The measurement of angle ∠D in parallelogram CDEF would be 89° and

the measurement of angle ∠D in parallelogram ABCD would be 57°.

A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

In parallelogram CDEF,

∠C = ∠D

87 = 93 + 2x

2x = 87 - 93

2x = -6

x = -3

So the measurement of ∠D = 93 + 2(-2) = 89

In parallelogram ABCD,

∠A =∠C

57 = 3x + 21

3x = 57 - 21

3x = 36

x = 12

So the measurement of ∠C = 3(12) + 21 = 57

Hence, the measurement of angle ∠D in parallelogram CDEF would be 89° and the measurement of angle ∠D in parallelogram ABCD would be 57°.

The statement postulate that can be used to determine BC is AC = AB + BC and the value of BC is 3 units

From the question, we understand that:

The point B is between the points A and C

Such that

AC = 10

AB = 7

By the straight lie postulate, we have

AC = AB + BC

Hence, the statement postulate that can be used to determine BC is AC = AB + BC

Recall that

AC = AB + BC

So, we have

10 = 7 + BC

Subtract 7 from both sides

BC = 3

A rectangle measuring 8 inches by 6 inches needs squares of side. A function in an in which the box's volume is 4a³-28a²+48a.

Given that,

A square measuring 8 inches by 6 inches needs squares of side. A cut out of each corner so that the sides can be folded into a box without a top.

How much area a box can occupy is determined by its volume. You need to know a box's length, width, and height in order to compute its volume. By multiplying the base area by the box's height, one can get the volume of a box.

The measurement of how much space an object may occupy is called volume, which is also known as capacity. Both regular and irregular objects may be present. Cubes, blocks, cylinders, pyramids, cones, and spheres are examples of common objects.

A:  area of the base

L: Length of the base

W: Width of the base

V(a)= (8-2a) (6-2a) (a)

V(a)= (48-16a-12a+4a²) (a)

V(a)= (48-28a+4a²) (a)

V(a)= 48a-28a²+4a³

V(a)=4a³-28a²+48a

Answer:

There is no “formula” and the sooner you stop believing that math is a collection of formulas the sooner you can start learning it.

“Y sinx”, as written, is meaningless. You probably meant y = sin(x). Learning the proper grammar and syntax for writing mathematical expressions is necessary to make any progress in the subject.

Finally, the value of y = sin(x) is the y-coordinate of a point on the unit circle at position angle x. the zeros of y = sin(x) are x = k*pi, where k is any integer, because at any of those position angles the y-coordinate will be 0. This is not a “formula”, just a compact way to indicate an infinite number of zeros. The note that k is any integer is generally assumed, but to be clear and precise it should be included as part of the answer.

Solutions to trig equations are often restricted to the domain [0, 2pi), which is once around the unit circle without repetition of any point. On this domain, the zeros are 0 and p

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry.

From the given information:

Triangle QRS, with vertices Q(6,2), R(7.7), and S(2,6)

Then we know that the

The coordinate geometry formula for area = the absolute value of Qx(Ry - Sy) + Rx(Sy - Qy) + Sx(Qy - Ry) divided by 2.

Then substitute the values:

Area = the absolute value of Qx(Ry - Sy) + Rx(Sy - Qy) + Sx(Qy - Ry) divided by 2.

Area = the absolute value of 6(7- 6) + 7(6- 2) + 2(2- 7) / 2.

Area =  6(7- 6) + 7(6- 2) + 2(2- 7) / 2.

Area =  6(1) + 7(4) + 2(-5) / 2.

Area =  6 +28 -10 / 2.

Area =  24 / 2.

Area =  12.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

From the given information:

f(x)=x^3+6x^2+17x+14​; slope of the tangent line=5

Then

f(x)=x^3+6x^2+17x+14

Now find the drivative then

f'(x)=3x^2+12x+17

Then slope of the tangent line=5

Now,

Answer:  [tex]\frac{dy}{dx}[/tex] = [tex]\frac{ 7 - sin y }{ -6 y^{2} + x cos y }[/tex]

Step-by-step explanation:

Given data,

                       x sin y - 2y^3 - 5 = 7x

Differentiate with each term with respect to the independent variable,

            [tex]\frac{d}{dx}[/tex] (x sin y) - [tex]\frac{d}{dx}[/tex] (2y^3) - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)  

Apply to the product rule,

         sin y * [tex]\frac{d}{dx}[/tex] (x) + x * [tex]\frac{d}{dx}[/tex] (sin y) - [tex]\frac{d}{dx}[/tex] (2 [tex]y^{3}[/tex]) - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)

Apply the chain rule,

sin y * [tex]\frac{d}{dx}[/tex] (x) + x* [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dy}[/tex] (2 [tex]y^{3}[/tex])* [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dx}[/tex] (5) = [tex]\frac{d}{dx}[/tex] (7x)

Take out the coefficients,

sin y * [tex]\frac{d}{dx}[/tex] (x) + x * [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] -2 [tex]\frac{d}{dy}[/tex] ([tex]y^{3}[/tex]) *  [tex]\frac{dy}{dx}[/tex] - [tex]\frac{d}{dx}[/tex] (5) = 7 * [tex]\frac{d}{dx}[/tex] (x)

Differentiate the constants and power functions,

 sin y + x * [tex]\frac{d}{dy}[/tex] (sin y) * [tex]\frac{dy}{dx}[/tex] - 2 * 3 * [tex]y^{2}[/tex] * [tex]\frac{dy}{dx}[/tex] = 7    

Differentiate sin (x),

  sin y + cos y * [tex]\frac{dy}{dx}[/tex] - 2 * 3 * [tex]y^{2}[/tex] * [tex]\frac{dy}{dx}[/tex] = 7

Isolate,

             [tex]\frac{dy}{dx}[/tex] = [ 7-sin y ] / (-6 [tex]y^{2}[/tex] + x cos y )

Therefore,

              [tex]\frac{dy}{dx}[/tex] = [tex]\frac{ 7 - sin y }{ -6 y^{2} + x cos y }[/tex]

(y = 2.05x) is the equation that relates the change in price per sticker purchased.

The equation of exchange is an economic identity that shows the relationship between money supply, the velocity of money, the price level, and an index of expenditures. English classical economist John Stuart Mill derived the equation of exchange, based on earlier ideas of David Hume. It says that the total amount of money that changes hands in the economy will always equal the total money value of the goods and services that change hands in the economy.

Given that: For every ten sheets you buy the total cost increases $20.50.

• The number of stickers purchased = 10

• Price change = $20.50

The change in price per sticker purchased can be expressed as:

• Price change / number of stickers

• Change in price per sticker = $20.50 / 10

• Change in price per sticker purchased = 2.05

Therefore, the required equation which related y and x is: y = 2.05x
