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

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

A standard lot is an amount of currency which is the same as 100,000 units of a base currency .

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.

By buying $100,000 at ¥110.00 and the price increases to ¥110.50, which indicates a 50 pip movement and a gain of $500 and vice versa.

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 value of the consecutive numbers are 7 and 8.

Consecutive integers simply means the numbers that follow each others. It should be noted that such numbers have the same difference between them.

From the information given, we want to find two consecutive positive integers such that the square of the second integer added to 6 times the first is equal to 106.

Let the numbers be x and x+1.

Therefore, 6x + (x + 1)² = 106

6x + x² + 2x + 1 = 106

Collect like terms

x² + 8x + 1 - 106

x² + 8x - 105

x² + 15x - 7x - 105

x(x + 15) - 7(x - 15) = 0

Therefore x - 7 = 0

x = 0 + 7

x = 7

Therefore x + 1

= 7 + 1

= 8

The numbers are 7 and 8.

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.

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.

The waterskier has a final speed of approximately 25.350 feet per second.

In this question we need to determine the final speed of the waterskier, that is, the final speed of the waterskier when she leaves the ramp. This can be done by means of the principle of energy conservation, where the total energy is the result of combining translational kinetic energy (K), in pounds-feet per second, related to the speed of the waterskier, and gravitational potential energy (U), in pounds-feet per second.

The equation that represents the situation is described below:

K = U + K'

0.5 · m · v² = m · g · h + 0.5 · m · v'²

0.5 · v² = g · h + 0.5 · v'²

v'² = v² - 2 · g · h

Where:

If we know that v = 30 ft / s, g = 32.174 ft / s² and h = 4 ft, then the final speed of the waterskier is:

v' = √[(30 ft / s)² - 2 · (32.174 ft / s²) · (4 ft)]

v' ≈ 25.350 ft / s

The final speed of the waterskier is approximately 25.350 feet per second.
