Concentric circles are internally tangent circles, true or false?

Answer:
The slope of the driveway is 0.2 or 20%.

Step-by-step explanation:

Grade is a measure of the steepness of a slope, typically expressed as a percentage. To convert a grade percentage to a slope, you can use the following formula:

Slope = Grade / 100

So in this case, the grade of the driveway is 20%, and using the formula above, the slope of the driveway would be:

Slope = 20 / 100 = 0.2 or 20%

Keep in mind that grade is an expression of the steepness of a slope, and slope is an expression of the incline of a line. They are related, but they are not the same thing. Grade is a percentage, while slope is a ratio, and they are used in different contexts.

In mathematics, the grade of a surface represents its steepness or incline. A driveway with a grade of 20% means it inclines or descends 20 units vertically for every 100 units horizontally. Therefore, the slope of this driveway is 20/100 or 0.2.

In the field of mathematics, particularly in geometry, the term grade is often used to express the steepness or incline of a surface, like a driveway. If a driveway has a grade of 20%, it means that for every 100 units you move horizontally, you'll ascend or descend 20 units vertically.

The slope of the driveway is represented by the same proportion: rise over run, or vertical change over horizontal change. Therefore, in this case, the slope of the driveway is 20/100 or 0.2 when expressed as a decimal.

So, a driveway with a 20% grade has a slope of 0.2.

Based on the data you provided, the proportion of chipped vae in the last 20 produced was 2/20 = 0.1.

Therefore, we would expect the number of chipped vae in the next 10 to be approximately 0.1 * 10 = 1.

The estimate of the number of chipped vae in the next 10 was determined by multiplying the proportion of chipped vae in the last 20 produced (0.1) by the number of vae to be produced in the next 10.

0.1 * 10 = 1

This estimate assumes that the proportion of chipped vae in the next production batch is the same as the proportion in the last 20. This is known as a point estimate and it's based on the information we have available.

Keep in mind that this is just a rough estimate and actual results may vary. Other factors such as changes in production processes or quality control measures may affect the proportion of chipped vae in the next batch.

The respective speeds of Blitzen and Nikolas are 28 miles per hour and 4 miles per hour.

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: Blitzen walks 7 times faster than nikolas and  nikolas walked 15 hours and rode blitzen for 3 hours to travel 144 miles.

Let the speed of nikolas be x then we have

speed of Blitzen as = 7x

x×15+3×7x=144

15x+21x=144

36x=144

x=4

∴ Speed of Blitzen = 28 miles per hour and Speed of Nikolas=4 miles per hour

Hence, The respective speeds of Blitzen and Nikolas are 28 miles per hour and 4 miles per hour.

The function calculation can be used to determine the value of f(6): f(6) = f(5) + 6 f '(x) (x) dx 5 f(6) = 14 + 6 f '(x) (x) dx 5 f(6) = 14 + 19 f(6) = 33

The values of f(5) and 6 f '(x) dx 5 can be used to get the value of f(6). Since f' is a continuous function by definition, it may be used to determine the area under the curve between any two locations using its derivative. The area between x=5 and x=6 can therefore be calculated using the definite integral 6 f' (x) dx 5. Adding the f value, which is equal to f(5), gives us f. (6). The definite integral 6 f' (x) dx 5 is 19 in this instance, while the value of f(5) is 14. Therefore, f(6) = f(5) + 6 f '(x) dx 5 = 14 + 19 = 33 can be used to compute the value of f(6). This demonstrates that f(6) has a value of 33.

Answer:

Yes, it is a function.

Step-by-step explanation:

Function is a mapping between two sets meaning we are creating a set of pairs where the first element of a pair comes from the first set and the second one from the second set. The first set is called function domain and the second one is called the set of function values.

There are two conditions that must be satisfied:

In our case the set: {-4, -1, 2, 5} would be our domain and the set: {8, 2, -4, 10} would be the set of values. We see that all elements of the domain have a pair and each of its element is paired with only one value (There are no pairs where for example -4 would be repeated as a first element).

The best step that Devin can take to find the equivalent to the fraction 5/6 would be to multiply the numerator and the denominator by 2. That is option A.

A fraction can be defined as the representation of the part of a whole value in a form of numerator and denominator.

For a fraction to be equivalent to another fraction the numerator must by divided or multiplied by a single common number.

That is;

5/6 = X/12

make X the subject of formula;

X = 5×12/6

X = 60/6 = 10

Therefore 5/6 = 10/12 when both the numerator and denominator are multiplied by 2.

What does math mean by percentage?

A value or ratio that may be stated as a fraction of 100 is referred to in mathematics as a percentage. If we need to determine a percentage of a number, we should divide it by 100 and multiply the result.

                        Therefore, the percentage refers to a portion per hundred. Per 100 is what the word percentage signifies. The letter "%" stands for it.

Decrease in price = 10.3 - 10

                               =  0.3 %

Percentage decrease in price = 0.3/10.3 * 100  = 300/103

To find the scale factor of similar figures ratio the equivalent sides of the original figure to the generated one.

The scale factor is the ratio obtained by dividing the equivalent side lengths of like figures. The ratios in the previous example were all reduced to 3/4, so we can conclude that the scale factor of the triangles LMN and QRS is 3/4. A scale factor can also be thought of as a multiplier.

When both the original dimensions and the new dimensions are known, the scale factor may be determined. The following is a basic formula to determine a figure's scale factor: Dimension of the new shape divided by Dimension of the previous shape is the scale factor.

The ratio that establishes the proportionality between the sides of like figures is known as the scale factor.

After translations function of g becomes g(x)=x²-1.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

The given function is f(x)=x².

When the shape is moved up by k units, then replace y with y + k.

When the shape is moved towards the left by k units, then replace x with x - k.

From the graph, we can see graph of function g is shifted 1 unit up and 2 units left.

Now, g(x)= f(x)+1-2

g(x)=x²-1

Write a distance equation:

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took.

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in meters (m) and time is in seconds (s), so the units will be in meters per second (m/s).

⇒90t + 70(t+1) = 100

⇒90t + 70t + 70 = 100

The probability that the first king is dealt out on the 13th card is 1/52.

(a) There are 4 aces and 4 kings in a standard deck of playing cards, so there are C(4,2) = 6 ways to choose 2 aces out of 4, and C(4,3) = 4 ways to choose 3 kings out of 4. Then, there are C(48,3) = 17, 296 ways to choose the remaining 3 cards from the remaining 48 cards in the deck.
