By using the differentials to approximate the possible propagated error in computing the area of the end of the log is ±2π

The measurement of the radius of the end of a log = 8 inches

The possible error of radius = 1/8 inches

The area of cross section of the end of the log = πr^2

A =  πr^2

dA / dr = 2πr

dA = 2πr(dr)

Here the possible error of radius = 1/8 inches

dr = 1/8 inches

Substitute the values in the equation

dA = 2π × 8 × (± 1/8)

= ±2π

Therefore, the possible propagated error in computing the area is ±2π

True, the given function f has an inverse.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y.  Inverse functions f and g result in f(x) = y if and only if g(y) = x.

Under the given condition, we can define the function g on the set of the images  {b | b = f(a), a belongs to A}  in a way

   g(b) = a,   if f(a) = b.

This function is defined correctly on this set and is the inverse function to f.

The equation which model the relationship between the weeks and the viewers is;

f(x) = 2160(1.5)ˣ

The distance between each number in a geometric series is known as the common ratio. The ratio between two consecutive numbers, or a number divided by the number before it in the sequence, is known as the common ratio since it is the same for all numbers or common.

Given that the expression f(x) = abˣ

Here, b is the common ratio.

Now to find the common ratio b;

To check for first and second term, 3240 / 2160 = 1.5

To check for second term and third term, 4860 / 3240 = 1.5

To check for third term and forth term, 7290 / 4860 = 1.5

To check for forth and fifth term, 10935 / 7290 = 1.5

Therefore the common ratio b is 1.5.

now to find a,

let x =0 and f(x) = 2160

Then, 2160 = a (1.5)°

a = 2160

Answer:

first do criss cross the it will be like this : 2(a-3)=4*5 . Now do like as given in the picture.

The surface area of a snowball can be represented by the formula:

A = 4πr^2

where A is the surface area, r is the radius of the snowball, and π is a constant approximately equal to 3.14.

If the surface area of the snowball decreases at a rate of 4 cm²/min, we can represent this as a derivative:

dA/dt = -4

where dA/dt is the rate of change of the surface area with respect to time, and t is the time in minutes.

The radius of the snowball is equal to half the diameter, so we can represent the radius as:

r = d/2

where d is the diameter of the snowball.

Substituting this expression for r into the formula for the surface area and differentiating with respect to time, we get:

dA/dt = 8π(d/2)dr/dt

Setting this expression equal to -4 and solving for dr/dt, we get:

dr/dt = -4 / (8π)

= -0.5 / π

When the diameter of the snowball is 39 cm, the rate at which the diameter decreases is:

dr/dt = -0.5 / π

= -0.15915494309189533576888376337251

Therefore, the rate at which the diameter of the snowball decreases when the diameter is 39 cm is approximately -0.159 cm/min.

By knowing that the cost equation must be a proportional relation, we will find that the equation is:

y = $0.64*x

The cost equation is proportional, if we define y as the cost and x as the number of pounds, the equation is something like:

y = k*x

We know that for (5 + 1/2) pounds the cost is $3.52, then we can replace these values in the equation above to get.

$3.52 = k*(5 + 1/2)

$3.52/(5 + 1/2) = k = $0.64

The graph of the linear equation y = (3/2)*x - 7

Can be seen in the image at the end.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Here we know that the slope is -2 and the y-intercept is -4, then the linear equation is:

y = -2x - 4

To graph that line we need to find two points on it, to get the points we need to replace the value of x.

if x = 0

y = -2x - 4

y = -4

So we have the point (0, -4)

And if x = 1:

y = -2*1 - 4

y = -6

So we have the point (1, -6)

Now we just need to graph these two points and connect them with a line.

The equation of the quadratic function is (c) f(x) = a(x + 3)² - 2

From the question, we have the table of values that can be used in our computation:

A quadratic equation is represented as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

From the graph, we have the vertex to be

(h, k) = (-3, -2)

Substitute (h, k) = (-3, -2) in f(x) = a(x - h)² + k

So, we have

f(x) = a(x + 3)² - 2

Also, from the graph, we have the point (0, 7)

This means that

a(0 + 3)² - 2 = 7

So, we have

9a = 9

Divide both sides by 9

a = 1

Substitute a = 1 in f(x) = a(x + 3)² - 2

f(x) = a(x + 3)² - 2

Hence, the equation is f(x) = a(x + 3)² - 2

To find when the populations of the two cities are equal, we can set P1(t) = P2(t) and solve for t:

120 e 0.011 t = 125 e 0.007 t

Dividing both sides by e 0.007 t:

120 = 125 * (e 0.011 t / e 0.007 t)

Using the property that e^(a+b) = e^a * e^b, we have:

120 = 125 * e^(0.011 t - 0.007 t)

120 = 125 * e^(0.004 t)

Dividing both sides by 125:

1.2 = e^(0.004 t)

Taking the natural logarithm of both sides:

ln 1.2 = ln e^(0.004 t)

ln 1.2 = 0.004 t

t = ln 1.2 / 0.004

t = approximately 8.44 years

Therefore, the populations of the two cities were equal approximately 8.44 years after 2004, or in the year 2012. To find the population of the two cities at this point in time, we can substitute t = 8.44 into either of the exponential functions:

P1(8.44) = 120 e 0.011 * 8.44 = approximately 123.88 thousand

P2(8.44) = 125 e 0.007 * 8.44 = approximately 123.88 thousand

Therefore, the populations of the two cities were equal to approximately 123.88 thousand when they were equal.

The graph of the given line with y-intercept -4 and slope 6 is given below.

What is slope intercept form?

One of the most popular ways to represent the equation of a line is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis).

For a straight line with slope "m" and y-intercept "b," the slope-intercept form equation is:

y = mx + b.

Given, y-intercept (b) = -4

slope (m) = 6

Then, the equation of the graph will be

The square root of 40 is approximately 6.324555320336759. This is the width of the rectangle.

What is a rectangle?

It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral. It occupies area in two-dimensional planner geometry.

The area of a rectangle is given by the formula A = lw,

where A is the area, l is the length, and w is the width.

We are told that the length of the rectangle is twice the width, so we can write the formula as follows:

A = 2w * w

We are also told that the area of the rectangle is 80 square inches, so we can substitute this value into the formula:

80 = 2w * w

We can rearrange this equation to solve for w:

80 = 2w²

w² = 40

The square root of 40 is an irrational number, so the width of the rectangle is an irrational number.

The sampling distribution of the sum S is roughly normal if the sample size is big (30 or more), according to the central limit theorem.

The central limit theorem tells us that the sampling distribution of the sum S is about normal because the sample size of 50 is at least 30.

The sum S's sample distribution has a mean and standard deviation of n and n, respectively.

The z-score is the value decreased by the mean, divided by the standard deviation

z = ( x -μS ) / √σS
