Since the graph was obtained by transforming the graph of the square root function, an equation for the function the graph represent is: \(g(x) = -\sqrt{9(x - 1)} + 2\)

In Mathematics and Geometry, a square root function is a type of function that typically has this form f(x) = √x, which basically represent the parent square root function i.e f(x) = √x.

In Mathematics and Geometry, a horizontal translation to the right is modeled by this mathematical equation g(x) = f(x - N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical equation g(x) = f(x) + N.

Where:

In this context, the required square root function can be obtained by applying a set of transformations to the parent square root function as follows;

f(x) = √x

g(x) = -√9(x - 1) + 2

\(g(x) = -\sqrt{9(x - 1)} + 2\)

The volume of the solid obtained by rotating the region between the curves x = 2√5y, x = 0, and y = 3 about the y-axis is 36π cubic units.

In calculus, finding the volume of a solid obtained by rotating a region about a line is an important topic. It involves using integration to calculate the volume of the solid.

To find the volume of the solid, we need to use the method of cylindrical shells. This involves taking thin slices of the solid perpendicular to the axis of rotation, finding their volume, and adding them up to get the total volume.

The first step is to sketch the region and the axis of rotation. In this case, the region is bounded by the curves x = 2√5y, x = 0, and y = 3, and the axis of rotation is the y-axis.

Next, we need to express the curves in terms of y. We can rewrite the equation x = 2√5y as y = x²/(20), and since the region is bounded by x = 0 and y = 3, the limits of integration are y = 0 and y = 3.

Now we can set up the integral for the volume using the formula for cylindrical shells:

V = 2π ∫(y)(f(y))dy from a to b,

where f(y) is the distance from the axis of rotation to the curve at a given value of y, and a and b are the limits of integration.

In this case, f(y) is simply the x-coordinate of the curve, which is x = 2√5y. Therefore, we have:

V = 2π ∫(y)(2√5y)dy from 0 to 3

Simplifying and evaluating the integral, we get:

V = 36π

The ship started at the Position 0.14 units.

To determine the starting position of the ship, we can consider the distance sailed to the left and the distance to the treasure.

Given that you sailed 0.055 units to the left and found the treasure at 0.085 units, we can represent this situation mathematically as follows:

Starting position + Distance sailed to the left = Distance to the treasure

Let's assign a variable, "x," to represent the starting position of the ship.

The equation becomes:

x - 0.055 = 0.085

To find the value of x, we can solve this equation by isolating x on one side:

x = 0.085 + 0.055

x = 0.14

Therefore, the ship started at the position 0.14 units.

The solution to the nonlinear system of equations is (x, y) = (-3, -2) and (x, y) = (1, 6). These points represent the coordinates where the two equations intersect and satisfy both equations simultaneously.

To solve the nonlinear system of equations:

Equation 1: \(y = -x^2 + 7\)

Equation 2: y = 2x + 4

We can equate the right sides of both equations since they both represent y.

\(-x^2 + 7 = 2x + 4\)

To simplify the equation, we can rearrange it to be in the standard quadratic form:

\(x^2 + 2x - 3 = 0\)

Now, we can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. In this case, let's use factoring:

(x + 3)(x - 1) = 0

From this equation, we get two possible solutions:

x + 3 = 0 => x = -3

x - 1 = 0 => x = 1

Now, we substitute these x-values back into either equation to find the corresponding y-values.

For x = -3:

y = 2(-3) + 4

y = -6 + 4

y = -2

For x = 1:

y = 2(1) + 4

y = 2 + 4

y = 6

The height of the antenna to the nearest foot is; 174 ft

Let us use h to represent the height of the tower.

Let us use d to represent the distance from the tower to first observation point.

From the diagram, we can deduce that;

h/d = tan 67°

h = d tan 67°

h/tan 67° = d  (eq 1)

Similarly;

h/(d + 100) = tan 45°

h = (d + 100) tan 45°

h/tan 45° = d + 100

(h/tan 45°) - 100 = d  (eq 2)

Set eq1 equal to eq 2 and solve for h to get;

h/tan 67° = (h/tan 45°) - 100

h/2.356 = h - 100

h - (h/2.356) = 100

Multiply through by 2.356 to get;

2.356h - h = 235.6

1.356h = 235.6

h = 235.6/1.356

h ≈ 174 ft

The probability is given by -0.001, that the mean of the sample would differ from the population mean by less than 0.9 watts.

What is normal probability distribution?

Normal distribution also known as the Gaussian probability, ia a probability distribution that is symmetric about the mean, showing that data bear the mean are more frequent in occurrence than data far from the mean.

In a set with mean μ and standard deviation (which is the square root of the variance) σ , the z score of a measure X is given by:

Z =X-μ/σ

we have given μ =129

σ = \(\sqrt{100}\) n = 96

This is the pvalue of Z when X = 129+1.7 =130.7 subtracted by the pvalue of Z when X = 129 - 1.7 = 127.3

When X = 130.7

Z =X-μ/σ

Z = 130.7-129/10

Z = 0.17  pvalue = 0.1699

When X = 127.3

Z =X-μ/σ

Z = 127.3-129/10

=-0.17 pvalue

0.1699 - 0.1700 = -0.001

Hence the probability is -0.001

The requried, local minimum and maxium for the given function is √2 and -√2.

We need to find the local maximum and local minimum of the function \(f(x) = 2x + 4x^{(-1)}.\)

First, we find the derivative of f(x):

\(f'(x) = 2 - 4x^{(-2)} = 2 - 4/x^2\)

Setting f'(x) = 0 to find the critical points:

\(2 - 4/x^2 = 0\)

Solving for x, we get:

x = ±√2

To determine whether these critical points are local maxima or minima, we need to examine the sign of the second derivative:

\(f''(x) = 8x^{(-3)}\)

When x = √2, f''(√2) = 8/(√2)³ = 8√2 > 0, so x = √2 is a local minimum.

When x = -√2, f''(-√2) = 8/(-√2)³ = -8√2 < 0, so x = -√2 is a local maximum.

Answer: f(n) = 2n - 2

Therefore, we can use this formula to find the value of f(n) for any positive integer n.

Step-by-step explanation: Using the given recursive formula:

f(1) = 0

f(n) = f(n-1) + 2

We can find the values of f(n) for different values of n:

f(1) = 0

f(2) = f(1) + 2 = 0 + 2 = 2

f(3) = f(2) + 2 = 2 + 2 = 4

f(4) = f(3) + 2 = 4 + 2 = 6

f(5) = f(4) + 2 = 6 + 2 = 8

And so on.

We can see that each term in the sequence is 2 more than the previous term. So, we can write the general formula for f(n) as:

f(n) = 2n - 2

Therefore, we can use this formula to find the value of f(n) for any positive integer n.

Answer:

Starting price is $50.70.

Next day the price is $50.70 + $17.75 = $68.45

This price then changed by: \(-3\frac{3}{4}\%=-3.75\%\).

So in order to calculate that we do: \(68.45 - (3.75/100*68.45)=65.883125 =\$65.88\)

Therefore final price is $65.88.

The height of the air ballon at 'm' minutes is expressed in the function and the value of h(3)=1600, h(9)=2800,h(11)=3200

We have given a function h in terms of m. Now we have to explain the contextual meaning of each and every expression it contains

1.) h = It is height at which ballon is cruising above from the ground level.

2.) m = It denotes the instance of minute at which we are talking about

3.) h(m) = The height as the function of minute, means the height of the ballon in changing with respect to the minute

4.) 1000 = It is the height at which ballon was cruising earlier and then started ascending

5.)200 = 200 feet the distance covered in a minute while ascending above

6.) 200m = distance ascended for 'm ' minutes

7.) 1000+200m = The total height that balloon covered after ascending for m minutes.

Now,

height at 3 minute = h(3) = 1000+200(3)=1000+600=1600

height at 9 minute = h(9) = 1000+200(9)=1000+1800=2800

height at x minute = h(x) = 1000+200(x)= 3200

1000 + 200x = 3200

200x = 2200

x = 11

Therefore, h(3) = 1600 , h(9)= 2800,h(11)=3200 are the different values of height 'h' at different 'm' minutes.
