First-order linear differential equations

kkurt [141]

Answer:

$(1)\ logy\ =\ -sint\ +\ c$

$(2)\ log(y+\dfrac{1}{2})\ =\ t^2\ +\ c$

Step-by-step explanation:

1. Given differential equation is

$\dfrac{dy}{dt}+ycost = 0$

$=>\ \dfrac{dy}{dt}\ =\ -ycost$

$=>\ \dfrac{dy}{y}\ =\ -cost dt$

On integrating both sides, we will have

$\int{\dfrac{dy}{y}}\ =\ \int{-cost\ dt}$

$=>\ logy\ =\ -sint\ +\ c$

Hence, the solution of given differential equation can be given by

$logy\ =\ -sint\ +\ c.$

2. Given differential equation,

$\dfrac{dy}{dt}\ -\ 2ty\ =\ t$

$=>\ \dfrac{dy}{dt}\ =\ t\ +\ 2ty$

$=>\ \dfrac{dy}{dt}\ =\ 2t(y+\dfrac{1}{2})$

$=>\ \dfrac{dy}{(y+\dfrac{1}{2})}\ =\ 2t dt$

On integrating both sides, we will have

$\int{\dfrac{dy}{(y+\dfrac{1}{2})}}\ =\ \int{2t dt}$

$=>\ log(y+\dfrac{1}{2})\ =\ 2.\dfrac{t^2}{2}\ + c$

$=>\ log(y+\dfrac{1}{2})\ =\ t^2\ +\ c$

Hence, the solution of given differential equation is

$log(y+\dfrac{1}{2})\ =\ t^2\ +\ c$

Mrs. Gomez is a mother to 2 boys. The number of children she has is three times the number of boys she has. Her children are pla

slava [35]

There are 6 children total, 4 of which are girls. The ratio is 2:1 girls:boys, so there will need to be twice as many pinks as there are blues. If we get 12 pinks, then there will be 6 blues. That's the biggest since that's all the pinks the florist has.

The diameter of a pearl is about 4 x 10-3cm and the diameter of an atom is about10-11m. How much larger than an atom is a pearl?

Ugo [173]

Answer:

D. 4 × 10⁶ times

Step-by-step explanation:

<u>The diameter of a pearl is </u>

4 × 10⁻³cm = 4 × 10⁻⁵ m

<u>The diameter of an atom is</u>

10⁻¹¹m

<u>How much larger than an atom is a pearl?</u>

4 × 10⁻⁵ ÷ 10⁻¹¹ = 4 × 10⁻⁵⁺¹¹ = 4 × 10⁶ times

Correct option is D

How much will you need to invest at 2.5% to have earned $900 in interest in 5 years

Evgen [1.6K]

Answer:

we need $7200 to earn $900 in 5 years.

Step-by-step explanation:

Simple Interest formula: $\frac{PRT}{100}$ .......where p is principal, r is rate of interest, t is time

Using the formula:

$\frac{p*2.5*5}{100} =900$

${p*2.5*5} =900*100$

$12.5p =90000$

$p = 90000/12.5$

$p=7200$
