Answer:
Wednesday is 45 to 18.
Thursday is 55 to 22
Step-by-step explanation:
Wednesday: The original ratio was 5 to 2 And the info tells us that the new ratio is ? to 18. To find the first part we have to find how we got from 2 to 18. 2 * 9 = 18. So to find out the first part you do 5 * 9 = 45. We multiply 5 because Thats the original 1st part. We multiply 9 because that's how we got to 18 in the 2nd part. So the answer is 45 for Wednesday.
Thursday: The original ratio was 5 to 2 And the info tells us that the new ratio is 55 to ?. To find the first part we have to find how we got from 5 to 55. 5 * 11 = 55. So to find out the 2nd part you do 2 * 11 = 55. We multiply 2 because That's the original 2nd part. We multiply 11 because that's how we got to 55 in the 1st part. So the answer is 22 for Thursday.

Answer:
perimeter of square=4×side
perimeter of square =4×13cm
perimeter of square = 52cm
area of square = side²
area of square = (13cm)²
area of square = 169cm²
Answer:
52 cm / 169 cm²
Step-by-step explanation:
To find the perimeter, we can add together the lengths of all the sides. Since the height and width of the square are the same length, we can tell all four sides are equal.
13 + 13 + 13 + 13 = 52
The perimeter is 52 cm.
The area is the length times the width of the shape, so we have to multiply 13 by 13.
13 · 13 = 169
The area is 169 cm².
The answer is the third option, 52 cm / 169 cm².

B) 50°
OC) 80°
OD) 90°
Answer:
Please mark be Brainliest and I hoped this helped!
x = 80°
Step-by-step explanation:
These are both isosceles triangles, so the top 2 angles are both 65°. The last angle of that triangle is 180° - (65° + 65°) which is 50°. Then, the opposite of that angle is in the next triangle. It is also 50°. So the 2 base angles are both 50°, so x is 180° - (50° + 50°) which is 80°.

\(1\frac{3}{4}\) feet as a multiplication expression using the unit, 1 foot, as a factor is \(1\frac{3}{4}\)×1.
The given fraction is \(1\frac{3}{4}\).
\(1\frac{3}{4}\) feet can be written as a multiplication expression as follows: 1 foot × 1 3/4. This is because \(1\frac{3}{4}\) is the same as 1 + 3/4.
Furthermore, 3/4 can be written as 0.75, which is the same as 0.75 × 1 foot.
Therefore, the multiplication expression is 1 foot × \(1\frac{3}{4}\) = 1 foot × (1 + 0.75) = 1 foot × 1 + 1 foot × 0.75 = 1 foot + 1.75 feet.
Therefore, \(1\frac{3}{4}\) feet as a multiplication expression using the unit, 1 foot, as a factor is \(1\frac{3}{4}\)×1.

Answer:
ƒ^(-1)(x) = x + 20
Step-by-step explanation:
To find the inverse of the function ƒ(x) = x - 20, we need to switch the roles of x and y and solve for y.
Let's start by replacing ƒ(x) with y:
y = x - 20
Next, swap x and y:
x = y - 20
Now, solve for y by isolating it:
x + 20 = y
Therefore, the inverse of the function ƒ(x) = x - 20 is given by:
ƒ^(-1)(x) = x + 20

The electric current to flow through the resistors and complete the circuit by reaching its intended destination or powering a device.
In the analogy of a circuit with resistance, we can compare it to an obstacle race. Here's how we can relate the different elements:
Circuit: The entire obstacle race course represents the circuit itself. It includes all the components and paths that the participants will go through.
Obstacles: The obstacles in the race represent the resistors in the circuit. Just like resistors impede the flow of electrical current in a circuit, obstacles in the race impede the progress of the participants.
People/Participants: The people participating in the race represent the flow of electric current in the circuit. They are the "charge" moving through the circuit, encountering and overcoming obstacles (resistors) to reach the finish line.
The goal of the participants (people) is to navigate through the obstacles (resistors) and complete the race (circuit) by reaching the finish line.

20 a) The area of a square field is 84642. A man takes 3 rounds of this field. Find the distance covered by him.
Answer:
So, the distance covered by man if he takes 3 rounds is 3491.16 inches
Step-by-step explanation:
We are given area of square field i.e 84642 and we need to find distance covered by man if he takes 3 rounds of the field.
Distance covered by man = Perimeter of square field
First we have to find length of side of square field.
The formula used is Area of square= (Length)^2
Putting value of area and finding length.
\(Area of square= (Length)^2\\\sqrt{Length} =\sqrt{84642} \\Length= 290.93\\\)
So, length of square field is 290.93 inches
Now finding the distance covered by man if he takes 3 rounds
First find perimeter
Perimeter of square = 4*length
Perimeter of square = 4*290.93
Perimeter of square = 1163.72 inches
Distance covered by man if he takes 3 rounds = 3*Perimeter of square
Distance covered by man if he takes 3 rounds = 3*1163.72
So, the distance covered by man if he takes 3 rounds is 3491.16 inches

Just remember that if you change , you must also change for its fundamental solution!
The solution for the linear system will be , x(t) = 4 c₁e^t + 4 c₂e^t and
y(t) = -c₂e^t + c₂(1 - t)e^t .
The solution is given by ,

Given that the matrix has repeated eigenvalue with eigenvector generalized vectors ,
λ = 1 with eigenvector v = [ 4 , -1 ] and generalized vectors w =[ 0,1 ].
then the solution will be,
c₁ [ 4 , 1 ] e^t + c₂[ 0 , 1] + [ 4 , -1 ] )e^t
therefore,
x(t) = 4 c₁e^t + 4 c₂e^t
y(t) = -c₂e^t + c₂(1 - t)e^t

Solve for y when 48/y = 12. Y=
The solution for y in the equation 48/y = 12 is y = 4 .
To solve for y in the equation 48/y = 12, we can multiply both sides of the equation by y to eliminate the denominator:
48/y * y = 12 * y
On the left side, the y in the denominator cancels out:
48 = 12 * y
Next, divide both sides of the equation by 12 to isolate y :
48/12 = y
Simplifying, we get:
4 = y
Therefore, the solution for y in the equation 48/y = 12 is y = 4 .

a rectangular doorway has a temporary support beam across its diagonal. the height of the doorway is 2 times its width. if the beam across the diagonal is 14 feet, how wide is the door?
Answer:
The door has a width of 6.26 feet, with a height of 12.52 feet.
Step-by-step explanation:
You can solve this by taking two pieces of information we're given:
1) the diagonal size of the doorway is 14 feet
2) the height of the doorway twice its width
First lets describe the width and height using the diagonal length. We can do that with the Pythagorean theorem:
w² + h² = 14²
Now we can use the relationship between the width and height to eliminate one variable:
w² + (2w)² = 14²
w² + 4w² = 14²
5w² = 196
w² = 39.2
w ≈ 6.26
So the door has a width of 6.26 feet, with a height of double that, 12.52 feet.
Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The width of the door is 6.26 ft or √(196/5)ft.
What is Pythagoras theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.
Given the length of the rectangular door is two times its width, therefore, the length and width of the rectangular door are,
Width = x
Length = 2x
Since the measure of the diagonal of the rectangular door is 14 feet, therefore, using the Pythagorus theorem we can write,
x² + (2x)² = 14²
x² + 4x² = 196
5x² = 196
x² = 196/5
x = 6.26099 ≈ 6.26ft
Hence, the width of the door is 6.26 ft or √(196/5)ft.

Answer:
(d) (1, 2)
Step-by-step explanation:
You want to know which of the given points satisfies the inequality.
GraphWe find it easiest to plot the given points on a graph of the solution. This shows us that (1, 2) is a solution to the inequality. (It lies in the solution area.)
__
Additional comment
Another way to choose the answer is to try each of the points in the inequality.
If you can visualize the boundary line (without plotting it) as a line with positive slope and a y-intercept of 2, you can more readily reject the first choice and accept the last choice. (0, 3) is above the y-intercept, and (1, 2) is to the right of it (in the solution space).
You may also recognize the x-intercept will be -3, so the second choice lies above the boundary line.
The darkness of the print is measured quantitatively using an index. If the index is greater than or

(a) What percentage of printing jobs will be acceptable? (4)
(b) If the mean cannot be adjusted, but the standard deviation can, what must be the new standard
deviation such that a minimum of 95% of jobs will be acceptable?
84.13% of the printing jobs will be acceptable.
The new standard deviation required to achieve a minimum of 95% of jobs acceptable is 0.121.
The darkness of the print is measured quantitatively using an index. If the index is greater than or equal to 2.0 then the darkness is acceptable. Anything less than 2.0 means the print is too light and not acceptable. The machines print at an average darkness of 2.2 with a standard deviation of 0.20.
The mean of the darkness of the print is µ = 2.2 and the standard deviation is σ = 0.20.Therefore, the z-score can be calculated as; `z = (x - µ) / σ`.The index required for acceptable prints is 2.0. Thus, the percentage of prints that are acceptable can be calculated as follows;P(X ≥ 2.0) = P((X - µ)/σ ≥ (2.0 - 2.2) / 0.20)P(Z ≥ -1) = 1 - P(Z < -1)Using the standard normal table, P(Z < -1) = 0.1587P(Z ≥ -1) = 1 - 0.1587= 0.8413.
To find the new standard deviation, we can use the z-score formula.z = (x - µ) / σz = (2.0 - 2.2) / σz = -1Therefore, P(X ≥ 2.0) = 0.95P(Z ≥ -1) = 0.95P(Z < -1) = 0.05Using the standard normal table, the z-score value of -1.645 corresponds to a cumulative probability of 0.05. Hence,z = (2.0 - 2.2) / σ = -1.645σ = (2.0 - 2.2) / -1.645= 0.121.

Expand:
\(f(z) = \frac{1}{z(z - 2)} \)
for ;
\( |z| > 2\)
Expand f(z) into partial fractions:
\(\dfrac1{z(z-2)} = \dfrac12 \left(\dfrac1{z-2} - \dfrac1z\right)\)
Recall that for |z| < 1, we have the power series
\(\displaystyle \frac1{1-z} = \sum_{n=0}^\infty z^n\)
Then for |z| > 2, or |1/(z/2)| = |2/z| < 1, we have
\(\displaystyle \frac1{z-2} = \frac1z \frac1{1 - \frac2z} = \frac1z \sum_{n=0}^\infty \left(\frac 2z\right)^n = \sum_{n=0}^\infty \frac{2^n}{z^{n+1}}\)
So the series expansion of f(z) for |z| > 2 is
\(\displaystyle f(z) = \frac12 \left(\sum_{n=0}^\infty \frac{2^n}{z^{n+1}} - \frac1z\right)\)
\(\displaystyle f(z) = \frac12 \sum_{n=1}^\infty \frac{2^n}{z^{n+1}}\)
\(\displaystyle f(z) = \sum_{n=1}^\infty \frac{2^{n-1}}{z^{n+1}}\)
\(\displaystyle \boxed{f(z) = \frac14 \sum_{n=2}^\infty \frac{2^n}{z^n} = \frac1{z^2} + \frac2{z^3} + \frac4{z^4} + \cdots}\)

Answer:

Step-by-step explanation:
M = 5rt^2- 2rv
Subtract 5rt^2 from each side
M-5rt^2 = 5rt^2- 2rv -5rt^2
M-5rt^2 = - 2rv
Divide each side by -2r
(M-5rt^2)/(-2r) =- 2rv / (-2r)
(M-5rt^2)/(-2r) =v
Answer:
\(v = -\frac{M-5rt^2}{2r}\)
Step-by-step explanation:
\(M = 5rt^2 - 2rv\)
Switch sides
\(5rt^2-2rv=M\)
Subtract \(5rt^2\) from both sides
\(5rt^2 - 2rv-5rt^2= M -5rt^2\)
Simplify
\(-2rv = M - 5rt^2\)
Divide both sides by \(-2r\)
