Answer:

(a) 2058 m2

Step-by-step explanation:

This track can be broken down into 4 components

A positive space rectangle and negative space rectangle in the middle.

A positive space circle, and negative space circle, due to there being 4 semicircles total at the end of each of the aforementioned rectangles.

Now we have to find the dimensions for all these shapes by simply looking at the image:

The total height is 56m (42m+7m+7m), that means Positive circle has a radius of 28m (56m diameter/2 = 28m radius).

The height for the negative space within the track is 42m, thus negative circle has a radius of 21m (42m diameter/2 = 21m radius)

Now for the rectangles:

Total length is 126m, and since we already found the diameter/radius of those semicircles, we can do simple subtraction to find the length of the rectangles: 126m-56m=70m.

Finding the height of both rectangles is easy, its the same as the circles:

Total height is 56m and negative space height is 42m.

Now we use those dimensions we found to calculate the area of all the shapes.

Positive circle area = (22/7)*(56m^2)=2464m2

Negative circle area = (22/7)*(42m^2)=1386m2

We now subtract the negative area from the positive area and we get a total circle area of 2464m2-1286m2=1078m2

Positive rectangle area = 56m*70m=3920m2

Negative rectangle area = 42m*70m=2940m2

Like we did with the circles, we subtract: 3920m2-2940m2=980m2

To finally find the total area of the tracks we add both areas we found together: (1078m2+980m2=2058m2)

So there's our answer!

P.S. This took a long time to solve so I hope it's appreciated :)

There are 9,999 natural numbers that have no more than 4 digits.

To determine the number of natural numbers that have no more than 4 digits, we consider the range of numbers from 1 to 9,999.

The natural numbers with no more than 4 digits include all numbers from 1 to 9 (which form the single-digit numbers), all numbers from 10 to 99 (which form the two-digit numbers), all numbers from 100 to 999 (which form the three-digit numbers), and all numbers from 1,000 to 9,999 (which form the four-digit numbers).

To calculate the total count, we can add the number of single-digit numbers, two-digit numbers, three-digit numbers, and four-digit numbers:

Single-digit numbers: 9 (from 1 to 9)

Two-digit numbers: 90 (from 10 to 99)

Three-digit numbers: 900 (from 100 to 999)

Four-digit numbers: 9,000 (from 1,000 to 9,999)

Adding these counts together:

9 + 90 + 900 + 9,000 = 9,999

Therefore, there are 9,999 natural numbers that have no more than 4 digits.

Answer:

For the fraction it will be 3/10 and percent will be 30%

Step-by-step explanation:

Answer:

Please double check what you've written

Step-by-step explanation:

Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.

If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.

You can therefore easily understand that it doesn't make sense to have a probability greater than 1, I would thus advise you to read the question more carefully.

The answer is 3/10 , Option D

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Probability Formula = f/n

where,

f is the number of times an event occurs

n is the total number of trials

Odds are a/b ;

probability is a/(a+b)

The odds of event happening is 7/3

Probability is 7/(7+3)=0.7 of the event happening.

So the probability of it not happening is 1–0.7= 0.3.

probability of it not happening is 3/10

Therefore Option D is the correct answer.

Answer:

(5,4)

Step-by-step explanation:

To solve a system of equations by substitution, you need to solve one of the equations for one variable (either x or y). In this case, we can solve the second equation for x: x=2y-3. Then substitute this expression into the first equation and solve for y: 5(2y-3)-y=21. Solving for y gives us y=4. Substitute this value back into the second equation and solve for x: x=2(4)-3=5. Therefore, the solution is (5,4).

Answer:

11/12

Step-by-step explanation:

The ratio of 44 pennies to 48 pennies can be simplified by dividing both numbers by their greatest common factor, which is 4:

44/4 : 48/4

11 : 12

So the ratio of 44 pennies to 48 pennies is 11:12.

To convert this ratio to a fraction, we can write:

11/12

This is already in the form of a fraction, so we don't need to simplify it any further.

Therefore, the ratio of 44 pennies to 48 pennies can be expressed as the fraction 11/12.

The sine rule is the ratio of perpendicular and hypotenuse. Then the length of the hypotenuse is 3 units.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

Then the length of the hypotenuse is given by the sine rule.

\(\rm \sin \theta = \dfrac{Perpendicular}{Hypotenuse}\)

We have

θ = 45°

P = 3√2

Then we have

\(\rm H = 3\sqrt2 \sin 45^o\\\\H = 4.2426 \times 0.7071\\\\H = 2.9999 \approx 3\)

If we are given that \(f0(x) = (x-2)^4 (x-1)^3\) for all x, we know that f(x) is a function that has relative extrema points. Since f'(1) = 0, we cannot determine whether x = 1 is a minimum or maximum value of f(x) based on this information alone, derivative of f(x) at x = 1

To determine whether x = 1 is a minimum or maximum value of f(x), we need to examine the behavior of the function around x = 1. This can be done by looking at the sign of the derivative of f(x) at x = 1. To find the derivative of f(x), we can use the product rule of differentiation.

If we let \(g(x) = (x-2)^4\) and\(h(x) = (x-1)^3,\) then we have\(f(x) = g(x)h(x).\) Applying the product rule, we get: \(f'(x) = g'(x)h(x) + g(x)h'(x)f'(1) = g'(1)h(1) + g(1)h'(1)g'(1) = 4(1-2)^3 = -32h'(1) = 3(1-1)^2 = 0\)
Substituting these values into our equation for f'(x), we get:
f'(1) =\((-32)(1-1)^3 + (1-2)^4(0) = 0\)

Since f'(1) = 0, we cannot determine whether x = 1 is a minimum or maximum value of f(x) based on this information alone. We would need to examine the second derivative of f(x) at x = 1 to determine the concavity of the function and whether the point is a minimum or maximum value.

Answer:

If a tangent segment and a secant segment intersect outside a circle, then the square of the measure of the tangent segment equals the product of the measures of the secant segment and its external portion.

42^2 = (18 + x)(18)

1,764 = 18(x + 18)

x + 18 = 98

x = 80

So the diameter of the reservoir is 80 meters.

The diameter of the reservoir shown above can be calculated based on the intersecting secant-tangent theorem as: 80 meters.

A diameter is a straight line segment that crosses the center of a circle thereby connecting two points on its circumference and it is twice the length of the radius of a circle.

To find the diameter (x), apply the intersecting secant-tangent theorem which states that:

AB² = AC(x + CA)

Substitute:

42² = 18(x + 18)

1,764 = 18x + 324

1,764 - 324 = 18x

1,440 = 18x

1,440/18 = x

x = 80 meters.

The interval notation for the graph :

The most appropriate graph to construct for the given data table is a line graph. It shows how the miles change over time between each individual data point, allowing us to observe the relationship between the number of days and miles driven.

A line graph is a suitable choice in this scenario because it visually represents the relationship between the number of days and the miles driven over time. In a line graph, the x-axis represents the number of days, and the y-axis represents the miles driven. Each data point (number of days, miles driven) is plotted on the graph, and a line is drawn connecting these points.

By using a line graph, we can observe the trend or pattern in how the miles driven change as the number of days increases. We can see if there is a linear or non-linear relationship between the variables and how the miles driven vary over time. The line connecting the points helps us visualize the overall trend and identify any significant changes or patterns in the data.

In contrast, a scatter plot would simply show the individual data points without connecting them, making it more suitable for displaying the distribution or clustering of data rather than showing the change over time.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

The region cut out of the ball \($x^2 + y^2 + z^2 \le 4$\) by the elliptic cylinder \($2x^2 + z^2 = 1$\), i.e., the region inside the cylinder and the ball is \($\frac{8\pi}{3} \sqrt{2} - \frac{4\pi}{3}$\).

The given region is cut out of the ball \($x^2 + y^2 + z^2 \le 4$\) by the elliptic cylinder \($2x^2 + z^2 = 1$\). We can think of the elliptic cylinder as an "ellipsis" that has been extruded up along the y-axis.

Since the cylinder only depends on x and z, we can look at cross sections parallel to the yz-plane.

That is, given a fixed x-value, the cross section of the cylinder is a circle centered at (0,0,0) with radius \($\sqrt{1 - 2x^2}$\). We can see that the cylinder intersects the sphere along a "waistband" that encircles the y-axis. Our goal is to find the volume of the intersection of these two surfaces.

To do this, we'll use the "washer method". We need to integrate the cross-sectional area of the washer (a disk with a circular hole) obtained by slicing the intersection perpendicular to the x-axis. We obtain the inner radius \($r_1$\) and outer radius \($r_2$\) as follows: \($$r_1(x) = 0\text{ and }r_2(x) = \sqrt{4 - x^2 - y^2}.$$\)

Since \($z^2 = 1 - 2x^2$\) is the equation of the cylinder, we have \($z = \pm \sqrt{1 - 2x^2}$\).

Thus, the volume of the region is given by the integral of the cross-sectional area A(x) over the interval \($[-1/\sqrt{2}, 1/\sqrt{2}]$\):

\(\begin{align*}V &= \int_{-1/\sqrt{2}}^{1/\sqrt{2}} A(x) dx \\&= \int_{-1/\sqrt{2}}^{1/\sqrt{2}} \pi (r_2^2(x) - r_1^2(x)) dx \\&= \int_{-1/\sqrt{2}}^{1/\sqrt{2}} \pi \left[(4 - x^2) - 0^2\right] dx \\&= \int_{-1/\sqrt{2}}^{1/\sqrt{2}} \pi (4 - x^2) dx \\&= \pi \int_{-1/\sqrt{2}}^{1/\sqrt{2}} (4 - x^2) dx \\&= \pi \left[4x - \frac{1}{3} x^3\right]_{-1/\sqrt{2}}^{1/\sqrt{2}} \\&= \frac{8\pi}{3} \sqrt{2} - \frac{4\pi}{3}.\end{align*}\)

Therefore, the volume of the given region is \($\frac{8\pi}{3} \sqrt{2} - \frac{4\pi}{3}$\).

The region cut out of the ball \($x^2 + y^2 + z^2 \le 4$\) by the elliptic cylinder \($2x^2 + z^2 = 1$\), i.e., the region inside the cylinder and the ball is \($\frac{8\pi}{3} \sqrt{2} - \frac{4\pi}{3}$\).
