There are 60 students in Kinsley's grade. 3 of the students are enrolled in health. What

1 answer:

4 0

5% of the kids are in health. I got this from simplifying 3/60 which is 1/20

After that, i set up this equation: 1/20 times x/100

I would then divide 20 and 100 to get 5 and that’s basically what I did

Find the general solution of {y}''-3y=8e^{3t}+4sin(t) .

babunello [35]

Answer:

$y(x)=C_1e^{\sqrt3t}+C_2e^{-\sqrt3t}-\frac{4}{3}e^{3t}-sint$

Step-by-step explanation:

We are given that linear differential equation

$y''-3y=8e^{3t}+4 sint$

Auxillary equation

$D^2-3=0$

$D=\pm \sqrt3$

C.F= $C_1e^{\sqrt3t}+C_2e^{-\sqrt3}$

P.I= $\frac{8e^{3t}+4sin t}{D^2-3}$

P.I= $\frac{8e^{3t}}{9-3}+4\frac{sint }{-1-3}$

P.I= $e^{ax}{\phi (D+a)}$ and $P.I=\frac{sinax}{(\phi D)}$ where D square is replace by - a square

P.I= $-\frac{4}{3}e^{3t}- sint$

Hence, the general solution

G.S=C.F+P.I

$y(x)=C_1e^{\sqrt3t}+C_2e^{-\sqrt3t}-\frac{4}{3}e^{3t}-sint$

SOMEONE PLEASE ANSWER AND I WILL GIVE BRAINLIEST :))A company makes poppy lapel pins. Each of them costs £1.10 to make. In Octob

Liono4ka [1.6K]

Answer: The company will make 720 dollars (I dont know the percentage out of that though).

Step-by-step explanation: 1.10 times 1000= 1100. 35 percent of that is 385 dollars worth to charity or 350 lapel pins. 1000 minus 350 equals 650. 650 times .6 equals 390. 390 times 3 dollars= 1170 dollars. 650 times .4 = 260. 260 divided by 2 = 130, 130 times 5 dollars equals 650 dollars. 650 plus 1170= 1820. 1820-1100= 720.
