A box is 10in. high, 20in. long, and 12in. wide. What is the longest poster you could fit in the box? Use pencil and paper. Explain why you can only fit one maximum-length poster in the box but you can fit multiple 22-in. posters in the same box.
The longest poster that can fit in the box must have dimensions of 10 inches (height) by 20 inches (length) by 12 inches (width).
To find the longest poster that can fit in the box, we need to determine the longest dimension of the box itself. Since the box is 10 inches high, the longest poster that can fit in the box must have a height of no more than 10 inches.
Now, we need to consider the other two dimensions of the box. The box is 20 inches long and 12 inches wide, so the longest poster that can fit in the box must have a length of no more than 20 inches and a width of no more than 12 inches.
As for why we can only fit one maximum-length poster in the box but we can fit multiple 22-inch posters in the same box, it's because the length and width of the box are larger than the length and width of the 22-inch poster.

What is reasonable estimate for the limit? Limit of f (x) as x approaches StartFraction pi Over 4 EndFraction f(x) =
The reasonable estimate for the limit of f(x) as x approaches π/4 is √2.
To find the limit, we need to evaluate the function f(x) as x approaches π/4. The function f(x) is not explicitly defined, so we'll need to use some known mathematical properties. One property is that the limit of the square root of x as x approaches a is equal to the square root of the limit of x as x approaches a (provided the limit exists).
Applying this property, we can rewrite the limit as the square root of the limit of x as x approaches π/4. Since x is approaching π/4, the value of x itself will be very close to π/4.
The limit of x as x approaches π/4 is simply π/4. Taking the square root of π/4 gives us the final answer, which is √2. Therefore, the reasonable estimate for the limit of f(x) as x approaches π/4 is √2.

Find an equation for the line tangent to the graph of the given function at the indicated point. 8 3) f(x): () = at at (4,2) X 1 4) f(x)=x2-x at (4, 12)
(a) tangent line to the graph of f(x) = x^3 at the point (4,2).
(b) equation of the tangent line to the graph of f(x) = x^2 - x at the point (4,12).
(a) To find the equation of the tangent line to the graph of f(x) = x^3 at the point (4,2), we need to find the slope of the tangent line at that point. We can do this by taking the derivative of f(x) with respect to x and evaluating it at x = 4. The derivative of f(x) = x^3 is f'(x) = 3x^2. Evaluating f'(x) at x = 4 gives us the slope of the tangent line. Once we have the slope, we can use the point-slope form of a linear equation to write the equation of the tangent line.
(b) Similarly, to find the equation of the tangent line to the graph of f(x) = x^2 - x at the point (4,12), we differentiate f(x) to find the derivative f'(x). The derivative of f(x) = x^2 - x is f'(x) = 2x - 1. Evaluating f'(x) at x = 4 gives us the slope of the tangent line. Using the point-slope form, we can write the equation of the tangent line.
In both cases, the equations of the tangent lines will be in the form y = mx + b, where m is the slope and b is the y-intercept.

Answer: x = 1.186
Step-by-step explanation:
To solve, we need to isolate the x variable.
Given:
\(5^{2x-1}=2^{x+2}\)
Log both sides of the equation:
\(Log(5^{2x-1})=Log(2^{x+2})\)
Log power property:
\((2x-1)Log(5)=(x+2)Log(2)\)
Distribute:
* Think of the Log(5) and Log(2) as a "regular number" that you can divide with, distribute with, etc
\(2xLog(5)-Log(5)=xLog(2)+2Log(2)\)
Add Log(5) to both sides of the equation and subtract xLog(2) from both sides of the equation:
\(2xLog(5)-xLog(2)=2Log(2)+Log(5)\)
Factor x from the terms on the left side of the equation:
\(x(2Log(5)-Log(2))=2Log(2)+Log(5)\)
Divide both sides of the equation by (2Log(5)-Log(2)):
\(x= \frac{2Log(2)+Log(5) }{2Log(5)-Log(2)}\)
Compute:
x = 1.186

Answer:
Step-by-step explanation:
The answer is 420 miles. 300 miles/25= 12; there are 12miles to each inch 12X25=300. there is only a ten-mile difference, so add a zero to the original 12 miles to get 120, and we now know there is a 120-mile difference plus the original 300 gives us 420

when the finite population correction factor is applied to the sample mean, the resulting standard error for the sample mean is equal to
The finite population correction factor (FPC) is a factor used when the sample size is more than 5% of the population size. It corrects for the bias that can occur when taking a sample from a finite population.
Applying the FPC to the sample mean results in the standard error for the sample mean being equal to the population standard deviation divided by the square root of the sample size times the FPC.
In other words, the standard error for the sample mean is equal to:
Standard Error = Population Standard Deviation/√(Sample Size*FPC)
The FPC is calculated by taking the reciprocal of the following formula:
FPC = (N-n)/(N-1), where N is the population size and n is the sample size.
In conclusion, applying the FPC to the sample mean reduces the bias that can occur when taking a sample from a finite population, and the resulting standard error for the sample mean is equal to the population standard deviation divided by the square root of the sample size times the FPC.

Step-by-step explanation:
a. Create a sort of complex exponential equation using a common base and solve.b. Then solve the exponential equation using logarithms.
We can solve a common base exponential equation of the form:
\(a^{f(x)}=b^{g(x)}\)With the one-to-one property to get:
\(f(x)=g(x)\)(a) In this case, we can take 4 as the common base, to get:
\(4^{f(x)}=4^{g(x)}\)For f(x), we can use a linear equation of the form mx + b like 6x + 9, and for g(x) we can make it equal to -x² (we can use whatever equation we want because we are creating the complex exponential equation), then we get:
\(4^{6x+9}=4^{-x^2}\)Since we have common bases, by means of the one-to-one property, we rewrite the above equation to get:
\(6x+9=-x^2\)Simplifying and factoring:
6x + 9 + x² = x² - x²
6x + 9 + x² = 0
(x + 3)² = 0
Then, the solution to this equation is -3
(b) Similarly, taking logarithms on both side we get:
\(\begin{gathered} Log(4^{6x+9})=Log(4^{-x^2}) \\ (6x+9)Log(4^{})=(-x^2)Log(4^{}) \end{gathered}\)By dividing both sides by Log(4), we get:
\(6x+9=-x^2\)As you can see, we got the same equation as in part (a), then the solution will be the same and it is x = -3
Solve by factoring.
