What are Exponents?Exponents are the method of writing numbers, especially large numbers, in terms of a base and an exponent, which is written as the power of base.
Given that,
5⁵ . 5ˣ = 5²
We have to use a multiplication rule for exponent here.
xᵃ . xᵇ = xᵃ⁺ᵇ
Using this,
5⁵⁺ˣ = 5²
⇒ 5 + x = 2
⇒ x = -3
p⁻³ . p⁻⁶ = p^y
Using the same rule of exponent,
p⁻³⁺⁻⁶ = p^y
⇒ y = -3 - 6 = -9
9² . 9⁻⁷ . 9ⁿ = 9⁻⁵
9²⁻⁷⁺ⁿ = 9⁻⁵
⇒ 2 - 7 + n = -5
⇒ n = 0
Hence the values of x, y and n are -3, -9 and 0 respectively.

Answer:
2. 26.2 m
3. 117.2 cm
Step-by-step explanation:
You want the perimeters of two figures involving that are a composite of parts of circles and parts of rectangles.
2. Semicircular archThe circumference of a circle is given by ...
C = πd . . . . . where d is the diameter
The length of the semicircle of diameter 12.6 m will be ...
1/2C = 1/2(π)(12.6 m) = 6.3π m ≈ 19.8 m
The two lighted sides of the rectangle have a total length of ...
3.2 m + 3.2 m = 6.4 m
The length of the light string is the sum of these values:
19.8 m + 6.4 m = 26.2 m
The length of the string of lights is about 26.2 meters.
3. Fan shapeThe perimeter of the figure is the sum of four quarter-circles of radius 11.4 cm, and 4 straight edges of length 11.4 cm.
Four quarter-circles total one full circle in length, so we can use the formula for the circumference of a circle:
C = 2πr
C = 2π·(11.4 cm) = 22.8π cm ≈ 71.6 cm
The four straight sides total ...
4 × 11.4 cm = 45.6 cm
The perimeter of the figure is the sum of the lengths of the curved sides and the straight sides:
71.6 cm + 45.6 cm = 117.2 cm
The design has a perimeter of about 117.2 cm.
__
Additional comment
The bottom 12.6 m edge in the figure of problem 2 is part of the perimeter of the shape, but is not included in the length of the light string.

What is the total area, in square centimeters, of the shaded sections of the trapezoid below?
The shaded areas therefore cover a total area of 86.84 cm2.
What is the total area?Let's calculate the whole trapezoid's area. You multiply by the height after adding the top and bottom sides and dividing the result by two.
To get the length of the top side, we sum the values that make up that side.
6.4+5.2+9.6=21.2
The underside is 5.2.
The top and bottom sides are added.
21.2+5.2=26.4
We multiply by 2.
26.4/2=13.2
We increase by the height, which is 6.2 as we can see.
13.2×9.1=120.12
Next, we locate the rectangle's unlit portion.
6.4×5.2 = 33.28
To get the total area of the two shaded triangles, we deduct this from the trapezoid's overall area.
120.12 - 33.28 = 86.84
The shaded areas therefore cover a total area of 86.84 cm2.

Suppose triangle ABC will be dilated using the rule D Subscript Q, two-thirds.
Point Q is the center of dilation. Triangle A B C is 6 units away from point Q. The length of A B is 3, the length of B C is 7, and the length of A C is 8.
What will be the distance from the center of dilation, Q, to the image of vertex A?
2 units
3 units
4 units
6 units
The distance from the center of dilation, Q, to the image of vertex A will be 4 units.
According to the given rule of dilation, D subscript Q, two-thirds, the triangle ABC will be dilated with a scale factor of two-thirds centered at point Q.
Since point Q is the center of dilation and the distance from triangle ABC to point Q is 6 units, the image of vertex A will be 2/3 times the distance from A to Q. Therefore, the distance from A' (image of A) to Q will be (2/3) x 6 = 4 units.
By applying the scale factor to the distances, we can determine that the length of A'B' is (2/3) x 3 = 2 units, the length of B'C' is (2/3) x 7 = 14/3 units, and the length of A'C' is (2/3) x 8 = 16/3 units.
Thus, the distance from the center of dilation, Q, to the image of vertex A is 4 units.

Find the volume of the solid whose base is the region bounded by y=x^2-5x+7, y=3, x=1, and x=4 if the cross sections taken perpendicular to the x-axis are rectangles with height x
The volume of the solid is 45/2 cubic units.
To find the volume of the solid, we need to integrate the area of each cross-section perpendicular to the x-axis along the interval [1, 4]. Since the cross-sections are rectangles with height x, we need to find the width of each rectangle at each value of x.
First, let's find the intersection points of the given curves. We can solve
\(y = x^2 - 5x + 7\)and y = 3 to get:
\(x^2 - 5x + 7 = 3\\x^2 - 5x + 4 = 0\\(x - 1)(x - 4) = 0\)
So the intersection points are (1, 3) and (4, 3).
Now, at each x value between 1 and 4, the width of the rectangle is the difference between the y values of the two bounding curves, which is:
\(3 - (x^2 - 5x + 7) = -x^2 + 5x - 4\)
Thus, the volume of the solid is:
\(V = \int [1,4] (-x^3 + 5x^2 - 4x) dx\)
Integrating, we get:
\(V = [-1/4 x^4 + 5/3 x^3 - 2x^2] from x = 1 to x = 4\\V = [(-1/4 \times 4^4 + 5/3 \times 4^3 - 2 \times 4^2) - (-1/4 \times 1^4 + 5/3 \times 1^3 - 2 \times 1^2)]\\V = [(-64/4 + 80/3 - 8) - (-1/4 + 5/3 - 2)]\\V = 45/2\)

The equatiion where C is the constant of integration.To evaluate the indefinite integral ∫(3e^x + 4x^5 - x^3/4 + 1)dx, we can integrate each term separately.
∫3e^x dx = 3∫e^x dx = 3e^x + C₁
∫4x^5 dx = 4∫x^5 dx = 4 * (1/6)x^6 + C₂ = (2/3)x^6 + C₂
∫-x^3/4 dx = (-1/4)∫x^3 dx = (-1/4) * (1/4)x^4 + C₃ = (-1/16)x^4 + C₃
∫1 dx = x + C₄

provide the missing information. the function f : = {(1, 5), (-2, 3), (-4, 2), (2, 5)} (is/is not) a one-to-one function. please respond only with: is or is not answer:
The function f: {(1, 5), (-2, 3), (-4, 2), (2, 5)} is a one-to-one function. It satisfies condition where each input value maps to unique output value, ensuring no repetition or multiple inputs leading to the same output.
A one-to-one function, also known as an injective function, is a type of function where each input value is uniquely mapped to an output value. In the given function f: {(1, 5), (-2, 3), (-4, 2), (2, 5)}, we can observe that each input value corresponds to a distinct output value. For example, the input 1 is mapped to the output 5, and no other input has the same output. Similarly, the inputs -2, -4, and 2 are associated with the outputs 3, 2, and 5 respectively, without any repetition.
This lack of repetition or duplication in the outputs demonstrates that the function is one-to-one. Each input has a unique correspondence with its output, and no two different inputs yield the same output value. Therefore, based on the provided set of mappings, we can conclude that the function f is indeed a one-to-one function.

In a certain investigation: 460 persons were involved in the study: and based on an enquiry on their age. it was known that 75% of them were 22 or more years. The following frequency distribution shows the age composition of the persons under study. Find the mean and modal life of condensers_ Mid; age in years No. of persons 18 f; 23 28 33 90 122 ; 38 56 48 24 20 33'
Therefore , the solution of the given problem of percentage comes out to be 38 years old is the median age.
What does a percentage actually mean?In statistics, a "a%" is a figure or statistic that is expressed as a percentage of 100. The words "pct," "pct," but instead "pc" are also not frequently used. However, the sign "%" is frequently used to represent it. The percentage sum is flat; there are no dimensions. Percentages are truly integers because their numerator almost always equals 100. Either the % symbol (%) or the additional term "fraction" must come before a number to denote that it is a percentage.
Here,
The following algorithm must be used to determine the mean age:
=> mean = (all years added together) / (total number of persons)
The representative age for each age group is the age that falls in the middle of the range. With this approach, we can determine the total age as follows:
=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)
=> 162 + 644 + 924 + 2970 + 4636 + 2688 + 1152 + 1520 + 272.25
=>18(9) + 23(28) + 28(33) + 33(90) + 38(122) + 56(48) + 48(24) + 76(20) + 1089(0.25)
According to the information provided, there are 460 people in total.
=> mean = 17745.25 / 460
=> mean = 17745.25 / 460
As a result, the average lifespan is roughly 38.552 years.
The age category in this instance with the highest frequency has a midpoint of 38 and a frequency of 122. As a result, 38 years old is the median age.

Toby is packaging 21 baseball cards and 12 football cards to sell at the swap meet. Each packet will have the same number of cards. Each packet will have the cards for only one sport. What is the greatest number of cards you can place each packet? How many packets would it be for each sport?
Answer: The greatest number of cards you can place each packet = 3
There would be 7 packets of baseball cards and 4 packets of football cards.
Step-by-step explanation:
Given: Number of baseball cards =21
Number of football cards = 12
Each packet will have the same number of cards.
Each packet will have the cards for only one sport.
Then, the greatest number of cards you can place each packet = GCD (21,12) i.e. greatest common divisor of 21 and 12
Since 21 = 3 x 7 and 12 = 2 x2 x3
so, GCD(21, 12)=3
So, the greatest number of cards you can place each packet = 3
Number packets of baseball cards = \(\dfrac{21}{3}=7\)
Number packets of football cards = \(\dfrac{12}{3}=4\)
So, there would be 7 packets of baseball cards and 4 packets of football cards.

12%
The probability of not selecting a green marble is equal to the total number of non-green marbles in the bag divided by the total number of marbles in the bag.
What is the meaning of probability and it will be calculated?To calculate the probability: there are three green marbles out of a total of twenty-five marbles, so the probability of selecting a green marble is 3/25.
The likelihood of not selecting a green marble is then 1 - 3/25 = 22/25.
This is equal to 22/25 * 100 = 88% as a percentage.
As a result, P(not green) = 88%
