Consider the following differential equation. y' + 5x^4y = x^4 Find the coefficient function P(x) when the given differential equation is written in the standard form \frac{dy}{dx} + P(x)y = f(x). P(x) = Find the integrating factor for the differential equation. e^\int P(x)dx = Find the general solution of the given differential equation. y(x) = Give the largest interval I over which the general solution is defined. (Think about the implications of any singular points. Enter your answer using interval notation.) Determine whether there are any transient terms in the general solution. (Enter the transient terms as a comma-separated list; if there are none, enter NONE.)

4. Halle $\lim_{x \to +\infty} f(x)$ y $\lim_{x \to -\infty} f(x)$. Si el valor del límite es infinito, indique si éste es $+\infty$ o $-\infty$. 1) $f(x) = x^3 - 4x^2 - 4$ 2) $f(x) = (1 - 2x)(x + 5)$ 3) $f(x) = \frac{x^2 - 2x + 3}{2x^2 + 5x + 1}$ 4) $f(x) = \frac{2x + 1}{3x^2 + 2x - 7}$ 5) $f(x) = \frac{3x^2 - 6x + 2}{2x - 9}$

Question 3. Predeposition and drive-in diffusion Boron is pre-deposited onto an initially pure silicon wafer for 20 minutes at 900°C within an environment which maintains the concentration of boron at the surface of the wafer at $1.5 \times 10^{20}$ atoms/cm³. a. Calculate the numbers of boron ions introduced in this step per unit area in unit of ions/cm². b. Calculate the diffusion length in unit of nm. c. Calculate the concentration (atoms/cm³) of boron at the diffusion length.

Question-3. As can be seen in the figure, the air conditioner operating in a stable state is external while the environment is 32°C, it keeps the indoor environment at 21°C. Roof and the 1s1 transfer speed from the walls to the housing 31,650 kJ/h according to the compressor of the air conditioner Is 2.2 kW power input enough? If it is enough, then, Calculate the COP, if it is not enough, theoretically it should be find the minimum required power in kW.

You are 31 years old, and decide to save $5,000 each year (with the first deposit one year from now), in an account paying 7% interest per year. You will make your last deposit 34 years from now when you retire at age 65. During retirement, you plan to withdraw funds from the account at the end of the year (first withdrawal at age 66). What constant amount will support you in retirement if you live to age 88, earning 4% p.a.?
