Can you Answer the question
Anyone please help if u know how to do this
Rewrite the given expression in the form 2^u where u is a constant or an algebraic expression.
1/2^5 = ? (Put the answer in exponential notation.)
To rewrite 1/2^5 in exponential notation, remember that 1/2^5 is the same as 2^-5. Therefore, 1/2^5 = 2^-5.
Rewrite the given expression in the form 2u where u is a constant or an algebraic expression.
To rewrite 1/25 in exponential notation, we need to understand that 1/25 is the same as (2-1)5. Using the property of exponents, we can rewrite this as 2-5, where -5 is the new exponent.
Therefore, 1/25 = 2-5, where u = -5.
The perimeter of a quarter circle is 32.13 what is the quarter circles radius
Follow below steps:
The problem involves finding the radius of a quarter circle given its perimeter. The perimeter of a full circle is known as its circumference, represented by the formula C = 2πr for a circle of radius r. However, for a quarter circle, only 1/4 of this circumference plus twice the radius (the straight sides of the quarter circle) constitutes the perimeter. Therefore, the perimeter (P) can be expressed as P = (πr)/2 + 2r.
Given that the perimeter is 32.13, we use the formula to set up the equation 32.13 = (πr)/2 + 2r. To solve for r, combine the like terms to get (2 + π/2)r = 32.13 and then isolate r by dividing both sides of the equation by (2 + π/2). Using the approximate value of π = 3.14159, you continue with the arithmetic to find the exact value of the radius.
Remember that precision is important in mathematics. When providing an answer, consider the number of significant figures supplied in the given data and maintain the same level of precision in the final answer.
The radius of the quarter circle is 20.48 units.
To find the radius of a quarter circle given its perimeter, we can start by understanding the formula for the perimeter of a circle.
The perimeter of a full circle is given by [tex]\( P = 2\pi r \)[/tex], where [tex]\( r \)[/tex] is the radius of the circle. Since we are dealing with a quarter circle, the perimeter would be one-fourth of the perimeter of a full circle.
The radius of the quarter circle as [tex]\( R \)[/tex]. Then, the perimeter of the quarter circle is [tex]\( \frac{1}{4} \times 2\pi R = \frac{\pi R}{2} \)[/tex].
The perimeter of the quarter circle is 32.13 units, we can set up the equation:
[tex]\[ \frac{\pi R}{2} = 32.13 \][/tex]
To solve for [tex]\( R \)[/tex], isolate it by multiplying both sides of the equation by [tex]\( \frac{2}{\pi} \)[/tex]:
[tex]\[ R = 2 \times \frac{32.13}{\pi} \][/tex]
[tex]\[ R \approx 20.48 \][/tex]
Explain how to estimate the product of 18.3(6.37).
the general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. if you see a digit greater than 5,round up, an if it's less than 5, round down. we would go to the right of 18.3 which would be (6.37), so we're going to to round that to the nearest whole number which would be 7 because it's more than 5. this shows how you estimate 18.3 an (6.37) hope this helps have a good day♡
how can you tell if radicals are like radicals
Answer and step-by-step explanation:
Like radicals have the same root (square root, cubed root, etc.) and the same expression under the radical sign.
In order to determine if two radicals are like, simplify both and then check both the root and the expression under the radical sign.

A biologist wants to estimate the median width of over 200 oak trees in a forest. Ten trees were selected at random, and their widths, in centimeters, were recorded. 63, 59, 12, 43, 71, 35, 28, 52, 47, 26 What is the estimated median width of all oak trees in the forest? Enter your answer in the box.
Answer:
45
Step-by-step explanation:
The estimated median width of all oak trees in the forest is 45 centimeters.
How to calculate the median width?
To estimate the median width of all oak trees in the forest, we can use the sample of ten trees that were selected at random.
First, we need to order the sample from smallest to largest:
12, 26, 28, 35, 43, 47, 52, 59, 63, 71
The median is the middle value in the ordered list. In this case, there are ten numbers in the list, so the median is the average of the fifth and sixth numbers:
median = (43 + 47) / 2 = 45
Therefore, the estimated median width of all oak trees in the forest is 45 centimeters.

An equation is shown below: 6(2x - 11) + 15 = 21 Write the steps you will use to solve the equation and explain each step.
The solution to the equation is 6 if equation is 6(2x - 11) + 15 = 21 the answer is 6.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a mathematical equation:
6(2x - 11) + 15 = 21
DIstributive property:
12x - 66 + 15 = 21
Subtraction property:
12x -51 = 21
Add 51 on both side:
12x -51 + 51 = 21 + 51
12x = 72 (adding like terms)
x = 6 (divide by 12 on both side)
Thus, the solution to the equation is 6 if equation is 6(2x - 11) + 15 = 21 the answer is 6.

Ferris wheel is drawn on a coordinate plane so that the first car is located at the point (30,0). What are the coordinates of the first car after a rotation of 270° about the origin?
Answer:
1. option A is correct i.e., [tex]\(90^{\circ}[/tex].
2. option B is correct.
3. the coordinates of the car after a rotation of [tex]\(270^{\circ}[/tex] is (0,-30).
Step-by-step explanation:
1. The angle of rotation is [tex]\(90^{\circ}[/tex].
To calculate the angle of rotation we can use a protractor and measure the angle between two corresponding angles, using point C as a center.
2. Given: ΔPRS with coordinates P(-3,2), R(2,5) and S(0,0) is rotated through an angle of 270°, the new image will be as follows;
The formula for rotation through 270° is: (x,y) → (y,-x)
hence our image will be at point:
P(-3,2)→P'(2,3)
R(2,5)→R'(5,-2)
S(0,0)→S'(0,0)
from the above, the approximate image will be option B.
3. Given: Ferris wheel is drawn on a coordinate plane at the point P(30,0). The coordinates of the car after a rotation of [tex]\(270^{\circ}[/tex] is (0,-30).
Because the formula for rotation through 270° is: (x,y) → (y,-x).
So, point P(30,0)→P'(0,-30).

In the diagram below, AC is perpendicular to BD. Find X.
Answer: The correct option is
(D) 17.5.
Step-by-step explanation: Given that in the diagram shown, AC is perpendicular to BD, where
[tex]m\angle BEC=(6x-15)^\circ,\\\\m\angle AED=(3y+12)^\circ.[/tex]
We are to find the value of x.
Since AC is perpendicular to BD and they are intersecting each other at the point E.
So, all the four angles made by this intersection are right angles.
That is, angle BEC is also a right angle.
Therefore, we get
[tex]m\angle BEC=90^circ\\\\\Rightarrow (6x-15)^\circ=90^\circ\\\\\Rightarrow 6x-15=90\\\\\Rightarrow 6x=105\\\\\Rightarrow x=\dfrac{105}{6}\\\\\Rightarrow x=17.5.[/tex]
Thus, the required value of x is 17.5.
Option (D) is CORRECT.

To solve this, we find the least common multiple (LCM) of 3 and 6. We find the prime factorization of each number:
3 = 3×1
6 = 2×3
We multiply the common factor, 3, by the uncommon factors, 2 and 1:
3×2×1 = 6
The LCM is 6; this means they will both have a quiz on the 6th day.
