The explicit function of the sequence is a(n) = 2(5)^n-1

The definition of the function is given as

2, 10, 50, 250, 1250

The above definitions imply that we simply multiply 5 to the previous term to get the current term

Using the above as a guide,

So, we have the following representation

a(1) = 2

Common ratio, r = 5

So, we have

a(n) = a * r^n-1

This givs

a(n) = 2(5)^n-1

Hence, the sequence is a(n) = 2(5)^n-1

The solution to the equations have the coordinates of (-6.61, 9.91) and (0.61, -0.91)

From the question, we have the following parameters that can be used in our computation:

f(x) = − ³/2 x and g(x) = (½)² – 1

Express the equation properly

So, we have

f(x) = -3/2x

g(x) = (1/2x)^2 - 1

Next, we make a plot of the system to determine the solution

The point of intersection in the plot represent the solution to the equations

In this case, the point of intersection has a coordinate of (-6.61, 9.91) and (0.61, -0.91)

Answer:

B

Step-by-step explanation:

Using the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = final amount

P = principal (starting amount)

r = annual interest rate (as a decimal)

n = number of times interest is compounded per year

t = time (in years)

We can plug in the given values:

P = $1,500

r = 0.0825 (8.25% expressed as a decimal)

n = 1 (compounded annually)

t = 2

A = $1,500(1 + 0.0825/1)^(1*2)

A = $1,500(1.0825)^2

A = $1,757.71

Therefore, the total balance after 2 years will be $1,757.71. Answer choice B is correct.

The distance is decreasing at a rate of 1028.30 miles/hour.

An indicator of how one quantity changes in proportion to another is called a rate of change. If x and y are the independent and dependent variables, respectively, then rate of change is equal to y-to-x conversions. Positive or negative change rates are possible.

Plane X: The first plane is due west of you, or at x = -280

traveling towards you at 560 mph

Plane Y: The second plane is due south of you, or at y = -450

traveling towards you at 900 mph.

D = Distance between the two planes.

D = √( x² + y² )

d/dt [ D ] = d/dt [ √( x² + y² ) ]

dD/dt = 1 / 2√( x² + y² ) (2XX' + 2YY')

dD/ dt = 1/2 √(-280)² + (-450)² (2 (-280)(560) + 2(-450)(900)

dD/ dt = 1/2 √(-280)² + (-450)² (2 (-280)(560) + 2(-450)(900))

dD/ dt = 1/ 530 (-140,000 - 405, 000)

dD/ dt = -1028.30

The percentage error made by the person is 25%.

To get the percentage error, multiply the relative error by 100%. In other words, first, calculate the difference between the true value and the measured value. Then, divide the obtained difference by the true value. Then take the absolute value of the obtained result and multiply it by 100%.

The measured value is 4 feet.

The true value is 3.2 feet.

So, the difference between the true value and the measured value is (4 feet - 3.2 feet), that is, 0.8 feet.

Now, divide the obtained difference by the true value.

(0.8 feet)/(3.2 feet) = 1/4

= 0.25

To get the percentage error, take the absolute value of the obtained result and multiply it by 100%.

|0.25|×100% = 0.25×100%

= 25%

Therefore, the obtained answer is 25%.

Answer:

The total cost of putting on the play is $500 for theater rental + $500 for actors + $750 for set decorations and costumes = $1750.

To reach the break-even point, the revenue from ticket sales needs to equal the total cost, so $1750 = $25 x (number of tickets sold).

Solving for the number of tickets sold, we can divide both sides by $25: $1750 / $25 = (number of tickets sold).

This gives us: 70 = number of tickets sold.

Therefore, Mr. Curry needs to sell 70 tickets to reach the break-even point.

Answer:

Step-by-step explanation:

The area of the field is 900√10 m².

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

Quadrilateral ABCD.

The longer diagonal connects vertices A and C, and let E and F be the feet of the perpendiculars from vertices B and D to the longer diagonal AC.

From the figure,

BE = 20 m

DF = 30 m

AE = EC = 120/2 = 60 m

Now,

The area of the quadrilateral.

The area of a trapezoid.

= (sum of parallel sides) x (height) / 2

Using the Pythagorean theorem,

AB² = AE² + BE²

60² + 20² = 4000

AB = √(4000)

AB = 20 √10

And,

CD² = CE² + DF²

CD² = 60² + 30²

CD² = 4500

CD = √(4500)

CD = 15 √20

Now,

Area = AB + CD x 1/2 x AC

= 20√10 + 15√20 x 1/2 x 120

= 900√10

Therefore,

The area of the field is 900√10 m².

The new volume can be calculated using the same formula:

V = Bh

V = π(2²)(11.14)

V ≈ 88.26 cubic inches

One possible true statement regarding the data is that there is a significant outlier in the dataset, which is the value of 1,820,000.

An outlier is an observation that is significantly different from other observations in the dataset, and it can have a big impact on the results of statistical analyses, such as the mean or the median.

In this case, the outlier value of 1,820,000 is much larger than the other values, which range from 45,000 to 65,000.

It is possible that this value represents a different type of house, or that it has some unique characteristics that make it much more expensive than the other houses on Hill Street.

To calculate the arc length of a circle, you need to use the formula: arc length = (central angle in radians) x (radius)

where the central angle is measured in radians and the radius is the distance from the center of the circle to the edge. To use this formula, first convert the central angle from degrees to radians by multiplying it by π/180. Then, multiply the result by the radius to find the arc length. For example, if you have a circle with a radius of 5 units and a central angle of 45 degrees, you can calculate the arc length as follows: Convert the central angle to radians: 45 x π/180 = 0.7854 radians. Multiply the central angle in radians by the radius: 0.7854 x 5 = 3.927 unit. Therefore, the arc length of a circle with a radius of 5 units and a central angle of 45 degrees is 3.927 units.

The sum of deviations of the individual observations from their sample mean is always equal to zero.

The sum of deviations of the individual observations from their sample mean is always equal to zero. This is because the sum of all the deviations is the sum of a positive and a negative value. When we add the negative value to the positive value, the net result is always zero.To illustrate this, let's take an example. Suppose we have a sample of 5 observations: 2, 4, 6, 8, 10. The mean of the sample is 6. The deviations of the individual observations from the sample mean can be calculated as follows:

The linear equation represented by the graph is y = 8x.

A linear equation is a mathematical equation that describes a straight line in a two-dimensional space. It can be written in the form of:

y = mx + b

where y and x are variables, m is the slope of the line, and b is the y-intercept of the line (the point where the line crosses the y-axis).

The slope, represented by "m", describes the steepness of the line, while the y-intercept, represented by "b", is the point where the line intersects with the y-axis.

Linear equations can also be written in other forms, such as the standard form:

Ax + By = C

where A, B, and C are constants, and x and y are variables. In this form, the equation describes a line in terms of its x and y intercepts.

Linear equations are used in a variety of fields, including mathematics, physics, engineering, economics, and more. They are useful for describing and predicting relationships between variables that exhibit a linear pattern.

The equation represented by the graph is a linear equation in the form of y = mx + b, where m is the slope and b is the y-intercept.

To find the slope, we can use the formula:

m = (y2 - y1)/(x2 - x1)

Let's choose the first two points (0.5, 4) and (1, 8):

m = (8 - 4)/(1 - 0.5) = 8

So, the slope is 8.

To find the y-intercept, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

Let's choose the point (0.5, 4) and the slope we just found:

y - 4 = 8(x - 0.5)

y - 4 = 8x - 4

y = 8x
