Write an equation for the nth term of the arithmetic sequence

Using the conversion factor, the height of Valerie in centimeters is (C) 160 cm.

A conversion factor is a quantity or formula required to change a measurement from one system of units to another system of the same measurement.

The amount is often expressed as a fraction or ratio with a multiplication factor.

For instance, 12 inches equals one foot when converting between inches and feet.

So, 64 inches in cm is:

We know that:

1 inch = 2.5 cm

Then, 64 inches is:
64 inches = 2.5 × 64

64 inches = 160

Therefore, using the conversion factor, the height of Valerie in centimeters is (C) 160 cm.

Answer:

x = 15 , y = 4

Step-by-step explanation:

If 3 or more parallel lines are intersected by two or more transversals, the parallel lines divide the transversals proportionally. then

[tex]\frac{x}{5}[/tex] = [tex]\frac{18}{6}[/tex] = 3 ( multiply both sides by 5 )

x = 15

and

[tex]\frac{12}{y}[/tex] = 3 ( multiply both sides by y )

12 = 3y ( divide both sides by 3 )

4 = y

The value of ∠A in triangle ABC is 40°

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of the angles of a triangle is always 180°

In the given triangle ABC,

∠A=7x-16°, ∠B=81°

By alternate segment theorem,

∠C=4x+27°

The sum of all the angle of a triangle is 180°.

∠A+∠B+∠C=180°

⇒7x-16+81+4x+27=180

11x=180-92

11x=88

x=8

So the value of ∠A=7×8-16 = 40°

The number of times that the cube will land on 5 if the number cube was rolled 500 times is 83 times.

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

It should be noted that in a number cube, we hage numbers from 1 to 6. The probability of getting a 5 is 1/6.

Therefore, when it's rolled 500 times, the possible number will be:

= 1/6 × 500

= 83 times.

A rational expression is simply a quotient of two polynomials. Or in other words, it is a fraction whose numerator and denominator are polynomials.

The rate of change of function [tex]f(x) = \sqrt{x} - \frac{1}{\sqrt{x}}[/tex] for x = 4 and x = 9 is 7 / 30.

We know that the rate of change of a function is nothing but the slope of the line.

The slope of the line is given by;

Slope = Change in y-coordinate / change in x-coordinate

We are given;

[tex]f(x) = \sqrt{x} - \frac{1}{\sqrt{x}}[/tex]

We need to find the rate of change of function for x = 4 and x = 9.

Let us find the value of y or f(x) for the given value of x.

For x = 4, [tex]f(x) = \sqrt{4} - \frac{1}{\sqrt{4}}[/tex]   = 2 - 1/2 = 4 - 1 / 2 = 3 / 2

For x = 9, [tex]f(x) = \sqrt{9} - \frac{1}{\sqrt{9}}[/tex]   = 3 - 1/3 = 9 - 1 / 3 = 8 / 3

Put the values of x and y in the slope formula, we will get;

Slope = (8 / 3 - 3 / 2) / (9 - 4) = 7 / 6*5 = 7 / 30

So, the rate of change of function is 7 / 30.

Thus, the rate of change of function [tex]f(x) = \sqrt{x} - \frac{1}{\sqrt{x}}[/tex] for x = 4 and x = 9 is 7 / 30.

The amount in the account after 25 years be $ 84,216.11

Given, an investment account is opened with an initial deposit of $18,500 earning 6.25% interest, compounded continuously.

We have to find the amount in the account after 25 years.

Now, on using the compound interest amount formula, we get

Amount = P(1 + r/100)^t

Amount = 18500(1 + 6.25/100)^25

Amount = 18500(1.0625)^25

Amount = 18500(4.55)

Amount = 84,216.1137

The formula for the area of a circle is given as follows:

A = πr².

The area of a circle of radius r is given by the multiplication of the number π and the square of the radius, according to the equation presented as follows:

A = πr².

Hence, for example, for a circle of radius of 5 units, the area is given as follows:

A = π x (5 units)² = 25π units².

The diameter of a circle is twice the radius, hence the radius is half the diameter, and as a function of the diameter, the area will be given as follows:

A = 0.25πd².

As the diameter in the context of this problem is:

r² = (0.5d)² = 0.25d².

The smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.

Given, a function

y = 1/2(x² - 8)

We have to find the smallest distance between origin and a point on the graph of y = 1/2(x² - 8).

Now, the point on the graph be,

( x , 1/2(x² - 8) ) and origin be (0 , 0)

Let the function of the distance between both the points be,

D = √(x - 0)² + (1/2(x² - 8) - 0)²

D = √x² + 1/4(x² - 8)²

D² =  x² + 1/4(x² - 8)²

On differentiating, we get

2DD' = 2x + x(x² - 8)

x³ + 2x - 8x = 0

x³ - 6x = 0

x(x² - 6) = 0

So, x = 0 , √6 , -√6

and the distance is minimum for x = √6

Therefore, using distance formula, we get

Distance = √(x1 - x2)² + (y1 - y2)²

Distance = √(0 - √6)² + (0 - (-1))²

Distance = √6 + 1

So, the smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.

Hence, the smallest distance between the origin and a point on the graph of y = 1/2(x² - 8) is √7 units.

There are three lot sizes;

In finance, a lot indicates a measure or increment of a commodity that can be transacted. Products are bought and sold using different lot sizes. Products such as spot forex are sold in lots of 100,000, 10,000, 1,000, or 100 units.

Competition and brokerage online has resulted in the introduction of various lot sizes and forms.

A change of $10 corresponds to a pip movement of a standard lot.

Answer:50.8%

Step-by-step explanation:

The slope-intercept form of the given line be,

y = -(9/8)x + 7

Given, a line is passing from two points (0 , 7) and (8 , -2)

we have to find the slope-intercept form of the equation of the line passing from the given points.

Using the slope-intercept form, we get

(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)

(y - 7)/(x - 0) = (7 - (-2))/(0 - 8)

(y - 7)/(x - 0) = 9/-8

-8(y - 7) = 9x

-8y + 56 = 9x

9x + 8y = 56

Slope-intercept form of the equation is,

y = -(9/8)x + 7

Hence, the slope-intercept form of the given line be, y = -(9/8)x + 7

The point slope form of equation is y- 3 = -4/3( x- (-3)).

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Points= (-3, 3) and (9, -13)

Now,

slope= (-13 - 3)/ (9 - (-3))

slope= -16 / 12

slope= -4/3

Now, the point slope form

y- [tex]y_1[/tex] = m (x- [tex]x_1[/tex])

y- 3 = -4/3( x- (-3))

y- 3= -4/3x - 4
