Answer 1

Answer:

[tex]x^4-20x^3 +175x^2 -750x+1250[/tex]

Step-by-step explanation:

By the conjugate root theorem, 5+5i is also a root.

[tex]f(x)=a(x-5)^2 (x-5-5i)(x-5+5i) \\ \\

= a(x^2 - 10x+25)((x-5)^2 - (5i)^2) \\ \\

= a(x^2 - 10x+25)(x^2 - 10x+25+25) \\ \\

= a(x^2-10x+25)(x^2-10x+50) \\ \\

= a(x^4- 10x^3 + 50x^2 - 10x^3 + 100x^2 - 500x + 25x^2 - 250x+1250) \\ \\

= a(x^4-20x^3 +175x^2 -750x+1250) \\ \\ [/tex]

The principle of superposition is a useful technique in developing solutions to differential equations after an initial solution is derived. In developing such solutions it is often convenient to consider separately the response of a system to initial conditions with all forcing function inputs equal to zero, and, secondly, the response to the forcing function with all initial conditions equal to zero. Consider the following differential equation:

dy/dt + ay= bus(t)

with y(c)=0

a. Determine the solution y_i(t) to the equation for nonzero, finite values of a and c, and for b = 0.
b. Determine the solution y_u(t) of the equation for nonzero, finite values of a and b, and for c = 0.

Answers

Answer:

A) [tex]y_{i}(t) = C.e^{-at}[/tex]

B) [tex]y_{u}(t) = - \frac{b}{a} e^{-at} + \frac{b}{a}[/tex]     t > s

Step-by-step explanation:

Attached below is a detailed solution of the given problem

Given equation:

dy/dt + ay = [tex]bu_{s}(t)[/tex]     with Y(c) = 0

A) Determine the solution [tex]Y_{i}(t)[/tex]

[tex]y_{i}(t) = C.e^{-at}[/tex]

B) Determine the solution [tex]Y_{u} (t)[/tex]

[tex]y_{u}(t) = - \frac{b}{a} e^{-at} + \frac{b}{a}[/tex]

A piece of paper has an area of 93.5 square inches. How many times does it need to be folded in half before the area is less than 1 square inch? Explain how you know.

Answers

Answer:

7 times.

Step-by-step explanation:

Keep dividing 93.5 by 2 until it becomes less than 1.

The sheet needs to be folded in half 7 times.

Since the area of the piece of paper is 93.5 square inches, and we need to fold the sheet in half it 'n' times  to get an area less than 1 square inch. This is written mathematically as 93.5(1/2)ⁿ ≤ 1.

So, dividing through by 93.5, we have

(1/2)ⁿ ≤ 1/93.5

(1/2)ⁿ ≤ 0.0107

taking natural logarithm of both sides, we have

㏑(1/2)ⁿ ≤ ㏑0.0107

n㏑(1/2) ≤ ㏑(0.0107)

n ≤ ㏑(0.0107)/㏑(1/2)

n ≤ -4.538/-0.693

n ≤ 6.55

Rounding up to the nearest whole number,

n ≅ 7

So, the sheet needs to be folded in half 7 times.

A car travels 136 miles using 7 gallons of gas. At that rate, how far can the car travel using 42 gallons of gas?

Answers

Answer:

in 136 miles=7 gallons

?=42 gallon

= 136=7

?=42

cross multiply

136×42=5,712

=5,712÷7=816

Answer:

816 miles

Step-by-step explanation:

136miles/7 g =19.43

19.43 x 42 ≅ 816.06

or

136/7 = X/42

solve for X

42/7 =6, then 136 x6= 816

x = 816 miles

You can figure out z by using ratios.

6/10=15/z

cross multiply

150=6z

150÷6=z

z=25 (Although, there is a problem with this.  If you use the Pythagorean theorem to find z, you get 28.8).

5. Cuando abrió sus puertas, una tienda de café ofrecía 6 tipos diferentes de
bocadillos. Desde entonces, agregó dos nuevos bocadillos cada semana.
Si la tienda ofrece ahora 28 bocadillos diferentes, ¿cuántas semanas (s) han
transcurrido desde su inauguración?
?

Answers

Answer:

11 weeks have passed.

Step-by-step explanation:

We can create a linear function that represents the number of bocadillos offered as a function of the number of weeks (s) that went by since the beginning (when the number of bocadillos was 6):

f(s) = 6 + 2 * s

Since now the number of bocadillos is 28, we can solve for s in the equation

28 = 6 + 2 * s

subtract 6 from both sides

28 - 6 = 2 * s

22 = 2 * s

divide both sides by 2

11 = s

Therefore, 11 weeks have passed.
