Stephen is combining all juice shown to make fruit punch. Does the expression (64+28+76)/6 make sense’s
Answers
Yes, the expression (64+28+76)/6 makes sense as it represents the average quantity of juice per unit when combining all the shown juices.
To determine whether the expression (64+28+76)/6 makes sense, we need to evaluate the components of the expression and consider whether the mathematical operations are valid.
The expression (64+28+76)/6 represents the sum of three numbers (64, 28, and 76), divided by 6. Let's break it down step by step:
Addition: We have three numbers being added together: 64, 28, and 76. The sum of these numbers is 168 (64 + 28 + 76 = 168).
Division: The sum of the three numbers, 168, is then divided by 6. Division is a valid mathematical operation.
Now, let's analyze whether the expression makes sense in the context of Stephen combining all the juice to make fruit punch. The numbers 64, 28, and 76 may represent quantities of juice (in some units) that Stephen is combining. However, without further information or context, we cannot determine if the expression accurately represents the combination of these juices.
If the numbers 64, 28, and 76 represent quantities of juice in the same units (such as milliliters or liters), then the expression (64+28+76)/6 would represent the average quantity of juice per unit. The result, 168/6, would be 28. This would imply that each unit (e.g., glass or serving) of the fruit punch contains an average of 28 units of juice.
In summary, mathematically, the expression (64+28+76)/6 is valid. However, without additional context regarding the units or quantities being represented, it is not possible to determine whether the expression accurately describes the process of combining the juices to make fruit punch.

Answers
The temperature at 8:00 A.M. was 15°C.
Using the given information:
1. At 7:00 P.M., the temperature was 16°C.
2. This temperature was 9°C less than the temperature at 2:00 P.M.
We can use this information to find the temperature at 2:00 P.M.:
Temperature at 2:00 P.M. = 16°C (temperature at 7:00 P.M.) + 9°C
Temperature at 2:00 P.M. = 25°C
3. The temperature at 2:00 P.M. was 10°C higher than the temperature at 8:00 A.M.
Now, we can find the temperature at 8:00 A.M.:
Temperature at 8:00 A.M. = 25°C (temperature at 2:00 P.M.) - 10°C
Temperature at 8:00 A.M. = 15°C

This year, a small business had a total revenue of 28900 . If this is 15% less than their total revenue the previous year, what was their total revenue the previous year?
Answers
The previous year's total revenue for the small business was approximately $25,130.43.
The total revenue of the small business the previous year can be calculated by finding the value that is 15% more than the revenue of $28,900 this year.
To determine the previous year's revenue, we can set up the equation:
Previous Year's Revenue + 15% of Previous Year's Revenue = $28,900
Let's solve the equation to find the previous year's revenue:
Let x be the previous year's revenue.
x + 0.15x = $28,900
Combining like terms, we have:
1.15x = $28,900
Dividing both sides by 1.15, we get:
x = $28,900 / 1.15 ≈ $25,130.43
Therefore, the previous year's total revenue for the small business was approximately $25,130.43.
We set up the equation by adding 15% of the previous year's revenue to the previous year's revenue. This is done to find the total revenue that is 15% more than the previous year's revenue. By solving the equation, we find that the previous year's revenue was approximately $25,130.43.

DQ2 Do all linear transformations have a matrix representation? If so, what theorem establishes this? If not, provide a counter-example
Answers
Yes, This is established by the Rank-Nullity Theorem, A counter-example would be a transformation that is not linear.
Yes, all linear transformations have a matrix representation. The theorem that establishes this is the Matrix Representation Theorem. This theorem states that given a linear transformation T : V → W where V and W are vector spaces over a field F, then there is a unique matrix A such that T(v) = Av for any v in V. This theorem proves that any linear transformation can be represented by a matrix.
A counter-example of a linear transformation that does not have a matrix representation is a transformation that maps a vector in one vector space to a vector in a different vector space. For example, if V is a vector space over the field F, and W is a vector space over another field K, then the linear transformation T : V → W does not have a matrix representation since the size of the matrix would need to be different for each vector in the different vector spaces.

determine the inverse of the function
Answers
Answer:
\(f^{-1}(x)= \dfrac{1}{2}\ln \left(-\dfrac{x^2}{x^2-1}\right), \quad \textsf{for}\:\{x:0 < x < 1\}\)
Step-by-step explanation:
Given function:
\(f(x)=\dfrac{e^x}{\sqrt{e^{2x}+1}}\)
The domain of the given function is unrestricted: {x : x ∈ R}
The range of the given function is restricted: {f(x) : 0 < f(x) < 1}
To find the inverse of a function, swap x and y:
\(\implies x=\dfrac{e^y}{\sqrt{e^{2y}+1}}\)
Rearrange the equation to make y the subject:
\(\implies x\sqrt{e^{2y}+1}=e^y\)
\(\implies x^2(e^{2y}+1)=e^{2y}\)
\(\implies x^2e^{2y}+x^2=e^{2y}\)
\(\implies x^2e^{2y}-e^{2y}=-x^2\)
\(\implies e^{2y}(x^2-1)=-x^2\)
\(\implies e^{2y}=-\dfrac{x^2}{x^2-1}\)
\(\implies \ln e^{2y}= \ln \left(-\dfrac{x^2}{x^2-1}\right)\)
\(\implies 2y \ln e= \ln \left(-\dfrac{x^2}{x^2-1}\right)\)
\(\implies 2y(1)= \ln \left(-\dfrac{x^2}{x^2-1}\right)\)
\(\implies 2y= \ln \left(-\dfrac{x^2}{x^2-1}\right)\)
\(\implies y= \dfrac{1}{2}\ln \left(-\dfrac{x^2}{x^2-1}\right)\)
Replace y with f⁻¹(x):
\(\implies f^{-1}(x)= \dfrac{1}{2}\ln \left(-\dfrac{x^2}{x^2-1}\right)\)
The domain of the inverse of a function is the same as the range of the original function. Therefore, the domain of the inverse function is restricted to {x : 0 < x < 1}.
Therefore, the inverse of the given function is:
\(f^{-1}(x)= \dfrac{1}{2}\ln \left(-\dfrac{x^2}{x^2-1}\right), \quad \textsf{for}\:\{x:0 < x < 1\}\)

An isosceles right triangle has legs of equal length. If the
hypotenuse is 10 centimeters long, find the length of each leg.
Answers
Answer:
\( \displaystyle 5\sqrt{2}\)
Step-by-step explanation:
we have a right angle isosceles triangle
in order to figure out the length of each leg we can consider Pythagoras theorem given by
\( \displaystyle {a}^{2} + {b}^{2} = {c}^{2} \)
remember that,
isosceles triangle has two equal legs so a=b and given that the the hypotenuse is 10
substitute:
\( \displaystyle {a}^{2} + {a}^{2} = {10}^{2} \)
simplify addition:
\( \displaystyle {2a}^{2}= 100\)
simplify square:
divide both sides by 2:
\( \displaystyle {a}^{2}= 50\)
square root both sides:
\( \displaystyle {a}^{}= \sqrt{50}\)
\( \displaystyle {a}^{}= 5\sqrt{2}\)
hence,
the length of each leg is 5√2

t
as your variable to represent the amount of time Zuri spent driving from Orlando to Tucson.
Equation:
b) How many miles is Orlando from Tucson?
Answer: miles
Answers
Orlando is approximately 1021.5 miles from Tucson.
a) Let's use the formula: distance = rate x time.
Let t be the time Zuri spent driving from Orlando to Tucson.
Then, the time she spent driving from Tucson to Orlando would be 49 - 10 - t = 39 - t (subtracting the time she stayed in Tucson and the time she already spent driving from Orlando to Tucson from the total time).
Using the formula, we can write two equations:
distance from Orlando to Tucson = 50t
distance from Tucson to Orlando = 55(39 - t)
The total distance traveled is the same in both directions, so we can set the two equations equal to each other and solve for t:
50t = 55(39 - t)
50t = 2145 - 55t
105t = 2145
t = 20.43
b) Now that we know the time it took for Zuri to travel from Orlando to Tucson, we can use one of the equations above to find the distance:
distance from Orlando to Tucson = 50t
distance from Orlando to Tucson = 50(20.43)
distance from Orlando to Tucson = 1021.5
Therefore, Orlando is approximately 1021.5 miles from Tucson.

The price after tax would be $
Answers
Answer:
Price of the printer is = $193.20

After 15% off price of the printer = $240 - 15% of $240

= $204
The store is offering $20 mail in rebate so the price of printer after rebate

then she earned 50 points , but later lost 80 points.
If we represent such on the number line, first we start at the origin (0). Then we move to the right 50 units (to the point 50), but then we are forced to move 80 units to the left. so we go back the 50 units to the zero, and 30 units more to the left (to complete suntracting the 80 units)

Now, if we write the expression 4 to the power 6 over 4 to the power 8 in standard form we get 4⁶/4⁸ and when we simplify this we get;
4⁶/4⁸ = 1/4² = 1/16
Now, if we write the expression 4 to the power 4 multiplied by 4 power 3 over 4 to the power 5 in standard form we get 4⁴×(4³/4⁵) and when we simplify this we get;
4⁴×(4³/4⁵) = 4⁴×(1/4²)
