123•47=5781
123•0.47=57.81

you can use the product of 123•47 to help you solve for the product of 123•0.47 by seeing that all you do is move the decimal yo the left 2 spaces. The reason you move the decimal to the left 2 spaces is because 47 is 0.47 just the decimal was moved 2 spaces to the right.

The perimeter , width and length are all one dimensional so the preimeter of the resulting rectangle  will be 2.5 * 36 = 90.

The area  is 2 dimensional  whereas the vase and height are one dimensional so the area will be increased by a factor of 5^2  ( or 25)
New  rea =  36*25 =  900

solids are 3 dimensional  so the ratio of thereir volumes is  5^3 : 3^3
= 125:27

to answer the last 2 use the formula Volume = pi r^2 h  where r = radius and h = height of a cylinder

y = c1 cos(5x) + c2 sin(5x) is a two-parameter family of solutions of the second-order DE y'' + 25y = 0. If possible, find a sol
TEA [102]

Answer:

y = 2cos5x-9/5sin5x

Step-by-step explanation:

Given the solution to the differential equation y'' + 25y = 0 to be

y = c1 cos(5x) + c2 sin(5x). In order to find the solution to the differential equation given the boundary conditions y(0) = 1, y'(π) = 9, we need to first get the constant c1 and c2 and substitute the values back into the original solution.

According to the boundary condition y(0) = 2, it means when x = 0, y = 2

On substituting;

2 = c1cos(5(0)) + c2sin(5(0))

2 = c1cos0+c2sin0

2 = c1 + 0

c1 = 2

Substituting the other boundary condition y'(π) = 9, to do that we need to first get the first differential of y(x) i.e y'(x). Given

y(x) = c1cos5x + c2sin5x

y'(x) = -5c1sin5x + 5c2cos5x

If y'(π) = 9, this means when x = π, y'(x) = 9

On substituting;

9 = -5c1sin5π + 5c2cos5π

9 = -5c1(0) + 5c2(-1)

9 = 0-5c2

-5c2 = 9

c2 = -9/5

Substituting c1 = 2 and c2 = -9/5 into the solution to the general differential equation

y = c1 cos(5x) + c2 sin(5x) will give

y = 2cos5x-9/5sin5x

The final expression gives the required solution to the differential equation.

Anastasy [175]
<span>The wallet contains 4 $1 bills, 4 $5 bills, and 4 quarters.

$1 </span>× 4 = $4
$5 × 4 = $20
$0.25 × 4 = $1
$4 + $20 = $24, $24 + $1 = $25.
