The mystery number 'm' that satisfies the stated conditions is - 8.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, Tameeka's mystery number be 'm'.

So, When you add 16 to mystery number then subtract 20,

m + 16 - 20,

you get the same result as when you add mystery number to itself, then add 20 and subtract 16,

m + m + 20 - 16.

Therefore,

m + 16 - 20 = m + m + 20 - 16

m - 4 = 2m + 4.

- m = 8.

m = - 8.

So the Tameeka’s mystery number (m) is -8.

The area under the curve y = 3x³ + 4x from x = 1 to x = 2 is 4 square units.

A curve is a continuous, smooth, and often repeating shape in the plane or in space. It is a geometric object that can be described mathematically by an equation or a set of points.

In mathematics, curves are used to model real-world phenomena and to study geometric and mathematical properties. For example, curves can be used to describe the shape of objects, the path of moving objects, or the graph of a mathematical function.

There are many types of curves, including lines, circles, ellipses, parabolas, hyperbolas, and spirals, among others. Each type of curve has unique properties and characteristics, and they are studied and used in different ways in different fields of mathematics and science.

In physics, curves are used to describe the motion of objects and the behavior of physical systems. For example, the trajectory of a projectile can be modeled by a parabolic curve, while the path of a planet around the sun can be modeled by an elliptical curve.

To find the area under the curve y = 3x^3 + 4x from x = 1 to x = 2, we can use the definite integral:

∫[1,2] (3x^3 + 4x) dx

To evaluate this integral, we can use the power rule for integration: ∫x^n dx = (x^(n+1))/(n+1) + C, where C is the constant of integration.

Using this rule, we get:

∫ (3x³ + 4x) dx = ∫ 3x³ dx + ∫ 4x dx = x^4/4 + 2x² + C

Evaluating this definite integral from x = 1 to x = 2, we get:

[tex][x^{\frac{4}{4}+2x^{2} } ]2-[x^{\frac{4}{4}+2x^{2} } ]1=(2^{\frac{4}{4} }+22^{2} ) -(1^{\frac{4}{4} } +21^{2} )=\frac{21}{4}-\frac{16}{4}=4[/tex]

Answer:

Below

Step-by-step explanation:

See diagram below   solve the angles in order 1-2-3-4-5-6

as shown in the diagram:

Answer:

85 degrees

Step-by-step explanation:

Okay, let's have a look at the triangle on the left.
We can see an exterior angle of 115 degrees, adjacent to the interior angle.
Thus, as they both form a line (180 degrees), Interior angle = 180 - 115
= 65 degrees
We know that all the angles of the triangle equal 180.
Now to find the remaining angle of the triangle on the left,
180 - (85 + 65) = 30 degrees

Moving towards the center, we have our interior triangle angle (30 degree), a 90 degree angle and an interior angle of the triangle on the right. So, as they all form a line, the interior angle of the triangle on the right will be
180 - (90 + 30) = 60 degrees

Also, on top of the triangle on the right, we have a 115 degree exterior angle again.
Repeating our first step, the interior angle would be 65 degree

Now to find the remaining angle of the triangle on the right,
180 - (30 + 65) = 95 degrees

This angle forms a line with another angle exterior to this one, so again,
180 - 95 = 85 degrees

The volume of the solid obtained by rotating the region bounded by x = y² and x = 1 − y² about x = 4 is 16.

The volume of a solid obtained by rotating a region about a line is calculated by using the method of cylindrical shells.

In this problem, we are given the region bounded by the curves x = y² and x = 1 − y², and we are asked to find the volume of the solid obtained by rotating this region about the line x = 4

Next, we set up a coordinate system with the y-axis being the axis of rotation and the x-axis being the height of the cylindrical shell.

We will be rotating the region about the line x = 4, so the width of the cylindrical shell is 4 - y².

The height of the cylindrical shell is the change in x from one shell to the next, which is given by the bounds of the region. The circumference of the shell is

=> 2πy,

and the width of the shell is 4 - y².

We integrate the product of these three quantities over the bounds of the region to find the total volume of the solid.

This integration can be done using a definite integral, with the bounds being the y-coordinates of the two points where the curves intersect.

The 7.5 liters of Solution A, 52.5 liters of Solution B, and 15 liters of Solution C were used to create the 60-liter mixture containing 29% acid.

Three solutions contain a certain acid.

A chemist combined all three solutions to create a 60-liter mixture containing 29% acid.

Let's call the amount of Solution A used in liters as x. Then, the amount of Solution B used would be (60 - x) liters and the amount of Solution C used would be 2x liters.

(0.15 * x) + (0.05 * (60 - x)) + (0.40 * 2x) = 0.29 * 60

Expanding and simplifying the equation, we get:

⇒0.30x + 3 - 0.05x + 2.4x = 17.4

Solving for x, we find that x = 7.5 liters of Solution A was used.

So, 7.5 liters of Solution A, 52.5 liters of Solution B, and 15 liters of Solution C were used to create the 60-liter mixture containing 29% acid.

My puppy is racing away from me at a rate of 200 feet per minute, while I am moving at a rate of 270 feet per minute. Yes, you will catch the puppy after 4 minutes

What is the relation between time and distance?

The relation between time and distance is defined as the ratio of speed and distance. We stand in the frame of reference where he is still, in this frame the speed of the puppy will be equal to the speed of the puppy in our previous frame plus the speed of him in the previous frame (because they are running in opposite directions). Speed =  270 - 220 = 50 feet per minute. My puppy is running away at a speed of 220 feet per minute. The distance between him and puppy = 200 feet Speed of him = 270 feet per minute.

For example if a car travels for 2 hours and covers 120 miles we can work out speed as 120 ÷ 2 = 60 miles per hour. The units of the the distance and time tell you the units for the speed.

You can determine if the inverse of a polynomial function is a function by using the Horizontal Line Test on the inverse.

The Horizontal Line Test is a graphical method that can be used to determine whether a given function is one-to-one, meaning that for each output value, there is at most one input value that maps to it.

If the inverse of a polynomial function is a function, it must pass the Horizontal Line Test, meaning that no horizontal line intersects the graph of the inverse more than once.

In other words, if the inverse of a polynomial function passes the Horizontal Line Test, it is guaranteed to have an inverse, which will be a function itself. If the Horizontal Line Test fails, then the inverse is not a function and does not have an inverse.

The coach made a mistake in converting the average rate from miles per hour to feet per second. To convert miles per hour to feet per second, the formula is (miles per hour) x (5280 feet/mile) / (60 minutes/hour) = (feet per second).

However, the coach used a different conversion factor, which resulted in an incorrect value. This incorrect value led the coach to conclude that Aliza was not running fast enough, when in reality, the actual rate could be higher than 8.2 feet per second.

Therefore, the coach made an error in the conversion factor used and in the conclusion based on the incorrect converted value.

Based on the residual plot, it is possible to determine whether a regression model is a good fit or not.

A residual plot is a scatterplot of the residuals (the differences between the actual values and the predicted values) against the predicted values. A good regression model should have residuals that are randomly distributed around zero and have roughly equal variance across the range of predicted values.

If the residuals form a pattern, such as a U-shape or a curve, it indicates that the model is not a good fit for the data. Additionally, if there are outliers or extreme values in the residual plot, it suggests that the model may not be appropriate for those observations.

The interquartile range is used to overcome the difficulty of range as a measure of variability which is affected by outliers.

The range is a measure of variability which is determined by calculating the difference between the highest and lowest values in a dataset. However, this measure of variability can be affected by outliers - values that are unusually high or low. For example, if a dataset includes one value that is much higher than the rest, then the range will be much higher than it would be without the outlier. The interquartile range is used to overcome this difficulty by ignoring the outliers when calculating the range. It is calculated by dividing the data into quartiles and then subtracting the lower quartile from the upper quartile. This gives a more reliable measure of variability as it ignores the outliers and is not affected by them.
