a norman window has the shape of a rectangle surmounted by a semicircle. (thus the diameter of the semicircle is equal to the width of the rectangle, labeled x.) a window with the shape of a rectangle surmounted by a semicircle. the diameter of the semicircle is equal to the width of the rectangle. the rectangle has width x. if the perimeter of the window is 32 feet, find the exact value of x (in ft) so that the greatest possible amount of light is admitted.
The exact value of x (in ft) so that the greatest possible amount of light is admitted is 8.96 ft
According to the question,
A norman window has the shape of a rectangle surmounted by a semicircle.
Let The width of rectangle be x and height be y
It is given that the diameter of the semicircle is equal to the width of the rectangle
Therefore , Diameter of circle = x
Radius = x/2
Perimeter of window = 32 = Perimeter of rectangle + Perimeter of semi-circle
=> 32 = Width + 2height + πr
=> x + 2y + πx/2 = 32
=> 2x + 4y + πx = 64
Solving for y,
=> 4y = 64 - 2x - πx
=> y = 64 - 2x - πx/ 4 ----------(1)
Area of the window = Area of rectangle + area of semi-circle
=> A = Width × hiegth + πx²/8
=> A = xy + πx²/8
Substituting the value of y from equation (1)
=> A = x ( 64 - 2x - πx/ 4 ) + πx²/8
[tex]A = x ( \frac{64 - 2x -\pi x}{ 4} ) + \frac{\pi x^2}{8}\\A = ( \frac{ 64x - x^2 ( 2 + \pi)}{4 } ) + \frac{\pi x^2}{8}[/tex]
Differentiating A w.r.t x
=> [tex]\frac{dA}{dx} = (\frac{64 - 2x(2 + \pi)}{4} ) + \frac{\pi x}{4}[/tex]
Now , To find a maximum area
dA/dx = 0
=> [tex]\frac{dA}{dx} = (\frac{64 - 2x(2 + \pi)}{4} ) + \frac{\pi x}{4} = 0[/tex]
Solving for x ,
64 - 4x - 2π + πx = 0
=> x = 64 / 4 + π ------(2)
Differentiating A again w.r.t x
=> d²A / dx² = -2(2 + π)/4 + π/4
=> -π+4 / 4 which is less than zero
Therefore,
Area is maximum when x = 64 / 4 + π
The exact value of x (in ft) so that the greatest possible amount of light is admitted is 8.96 ft

Step-by-step explanation:
Let A be a square matrix. Assume that the following statement is true: If B is an invertible matrix then rank BA = rank A. (a) Show that if B is an invertible matrix then rank AB = rank A. Hint: What is rank(AB)" ? (b) Show that for any invertible matrix P, rank(P-'AP) = rank A. (c) If P is invertible then nullity P-'AP = nullity A.
We proved the expression rank(AB)=rank(B) and rank(BA)=rank(B),
where A and B are the two matrices of same order.
Given, A is a square matrix.
If A is invertible and a n×n square matrix of full rank.
Since both AB and BA exist, where B is also a n×n square matrix.
rank(B)=rank(BT)
On using the rank–nullity theorem, we get
nullity of a matrix be n minus the rank of the matrix.
So let U be a matrix whose columns are a basis for the nullspace of AB, so that ABU = 0.
Pre-multiplying both sides by A−1 , we obtain BU=0,
As B and AB have the same rank.
Similarly, let V be a matrix whose columns are a basis for the null space of ATBT, so that ATBTV=0 .
Pre-multiplying both sides by (A−1)T , we get
BTV=0.
Since rank(BT)=rank(B) and rank(ATBT)=rank((BA)T)=rank(BA)
we get rank(AB)=rank(B) and rank(BA)=rank(B).
So, rank(AB)=rank(B) and rank(BA)=rank(B).
Hence, rank(AB)=rank(B) and rank(BA)=rank(B).

the diagrqam shows an object with a mass of 1.0 kiolgram attached to a string 0.50 merer long. the object is moving at a constant speed of 5.0 meters per second in hporizontal circular path with center at point o
The object is undergoing uniform circular motion. The radius of the circular path is equal to 0.50 meters. The centripetal force, F, acting on the object can be calculated using the equation F= mv^2/r in hporizontal circular path
m is the mass of the object, v is the velocity of the object and r is the radius of the circular path.
F = (1.0 kg) (5.0 m/s)^2 / 0.50 m
F = 50.0 kg m/s^2
The object is undergoing uniform circular motion, which means it is moving at a constant speed in a circular path with its center at point O. The radius of the circular path is equal to 0.50 meters. The force acting on the object is known as the centripetal force, and can be calculated by using the equation F= mv^2/r. This equation requires the mass of the object (m), its velocity (v), and the radius of the circular path (r). In this case, the mass is 1.0 kg, the velocity is 5.0 m/s, and the radius is 0.50 m. Plugging these values into the equation gives the centripetal force acting on the object as 50.0 kg m/s^2.

The perimeter of Dawna's new flat screen television is 70 inches. The ratio of its length to width is 4:3. Write and solve an algebraic equation to determine the dimensions of the television.
Answer:4*3+70=840
Step-by-step explanation:
Perimeter = 2(Length + Width)
length = 4x ; width = 3x ; perimeter = 70
SOLUTION:Perimeter = 2(Length + Width)
70 = 2(4x + 3x)
70 = 2(7x)
70 = 14x
x = 5
Length = 4x = 4(5) = 20 inchesWidth = 3x = 3(5) = 15 inchesCHECKING:Perimeter = 2(Length + Width)
70 = 2(20 + 15)
70 = 2(35)
70 = 70
We proved and checked the answer.Therefore, the length of the screen television is 20 inches while the width is 15 inches.CREDITS:heart and star pls <3 brainliest will be appreciated <3(っ◔◡◔)っ -{ elyna s }-

what is the square root of 81
Answer: I hope this is helpful
Step-by-step explanation:
The square root of 81 is 9 and you can say -9
We can find the square root of 81 using prime factorization method, or repeated subtraction method.
81 is a perfect square number and it is the fourth power of 3. we will calculate the square root of 81 by repeated subtraction method and solve a few interesting problems.Square Root of 81: √81 = 9
The square root of a number is the number that when multiplied to itself gives the original number as the product. Finding the square root of a number is the inverse of squaring a number. 81 = a × a = a2 Thus, a = √81= √(9 × 9)9 × 9 = 81 or -9 × -9 = 81. Therefore √81= ± 9This shows that 81 is a perfect square.

a manufacturer of detergent claims that the contents of boxes sold weigh on average at least 16 ounces. the distribution of weight is known to be normal, with a standard deviation of 0.4 ounce. a random sample of 16 boxes yielded a sample mean weight of 15.84 ounces. test at the 10% significance level the null hypothesis that the population mean weight is at least 16 ounces.
As there is sufficient evidence to conclude that the population mean weight is at least 16 ounces.
What is standard deviation ?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Think about the following data: 2, 1, 3, 2, 4. The average and the total square of the observations' departures from the mean will be 2.4 and 5.2, respectively. This means that (5.2/5) = 1.01 will be the standard deviation.
The following null and alternative hypotheses need to be tested
H0 : µ = 16
Hα : µ < 16
This corresponds to a left-tailed test , for which a z-test for one mean, with known population standard deviation will be used.
Based on the information provided, the significance level is α = 0.1, and the critical value for the left-tailed test is [tex]Z_{c}[/tex] = -1.28
The rejection region for this left-tailed test is R = {z : z < -1.282}
The z-statistics is computed as follow
[tex]z = \frac{X - µ _{0} }{sigma / \sqrt{n} }[/tex]
= (15.84 - 16) / (0.4 / √16)
= -1.6

find the least positive integer $n$ such that the set of $1000$ consecutive integers beginning with $1000\cdot n$ contains no square of an integer.
The difference between consecutive integral squares must be greater than 1000. (x+1)^2-x^2>=1000, so x>=999/2 implies x>=500. x=500 does not work, so x>500. Let n=x-500. The sum of the square of n and a number a little over 1000 must result in a new perfect square. By inspection, n^2 should end in a number close to but less than 1000 such that there exists 1000N within the difference of the two squares. Examine when n^2=1000. Then, n=10sqrt(10). One example way to estimate sqrt(10) follows.
3^2=9, so 10=(x+3)^2=x^2+6x+9. x^2 is small, so 10=6x+9. x=1/6 implies sqrt(10)\approx 19/6. This is 3.16.
Then, n approx 31.6. n^2<1000, so n could be 31. Add 500 to get the first square and 501 to get the second. Then, the two integral squares are 531^2 and 532^2. Checking, 531^2=281961 and 532^2=283024. 282,000 straddles the two squares, which have a difference of 1063. The difference has been minimized, so N is minimized N=282000 implies 282
