Answer:

Area of rectangle = 448

Area of semi circle = 402.1

Total area = 850.1

Step-by-step explanation:

Area of rectangle = length times width

Given length = 32 cm

Given width = 14 cm

Area = 32 * 14 = 448

Area of semi circle = πr² / 2

where r = radius

Given diameter = 32cm

To convert diameter to radius simply divide by 2

32 / 2 = 16

So radius 16

now we plug 16 into the formula

$A=\frac{\pi 16^2}{2} \\16^2=256\\256\pi =804.25\\\frac{804.25}{2} =402.12\\A=402.1$ (rounded)

Total area = area of semi circle plus area of rectangle

total area = 402.1 + 448 = 850.1

Answer:

Solution given:

length [l]:diameter [d]:32cm

breadth [b]:14cm

radius [r]=32/2=16cm

Area of semi circle:½πr²=½*πx16²=<u>402.12cm</u>²

Area of rectangle:l*b=32*14=<u>448cm</u>²

Total area =402.12cm²+448cm²=<u> </u><u> </u><u>850.12cm²</u>

Name the polygon. Write whether it is regular<br> or not regular.

andrew-mc [135]

Answer:

since the polygon has eight sides, it's an octagon and no, it's not regular since length of all sides of a regular polygon must be equal but in that octagon, not all sides are equal.

Dada a Matriz A= [1 -2 1 ][-3 1 4] [0 6 8] , escreva uma matriz B diferente de A, tal que detA =detB.

Mariulka [41]

Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.

$\mathbf A=\begin{bmatrix}1&-2&1\\-3&1&4\\0&6&8\end{bmatrix}$

$\mathbf B=\mathbf A^\top=\begin{bmatrix}1&-3&0\\-2&1&6\\1&4&8\end{bmatrix}$

Which of the following functions are solutions of the differential equation y" + y = 7 sin(x)? (Select all that apply.)

Nikitich [7]

The homogeneous equation

y'' + y = 0

has characteristic equation

r² + 1 = 0

with roots at r = ± √(-1) = ± i, and so the characteristic solution is

y = C₁ cos(x) + C₂ sin(x)

Using the method of undetermined coefficients, suppose

y = a x cos(x) + b x sin(x)

(we would normally consider y = a cos(x) + b sin(x), but cos(x) and sin(x) are already part of the characteristic solution)

The derivatives are

y' = a cos(x) - a x sin(x) + b sin(x) + b x cos(x)

y' = (b - a x) sin(x) + (a + b x) cos(x)

and

y'' = -a sin(x) + (b - a x) cos(x) + b cos(x) - (a + b x) sin(x)

y'' = (-2a - b x) sin(x) + (2b - a x) cos(x)

Then

y'' + y = (-2a - b x) sin(x) + (2b - a x) cos(x) + a x cos(x) + b x sin(x)

7 sin(x) = -2a sin(x) + 2b cos(x)

and it follows that a = -7/2 and b = 0.

So, the general solution to the DE is

y = C₁ cos(x) + C₂ sin(x) - 7/2 x cos(x)

which means the only valid solutions from the given choices are

y = 7 sin(x)

y = 7 cos(x)
