Which of the following is the solution to the differential equation....

Mathematics
1 answer:
bixtya [17]3 years ago
4 0

Answer:

B

Step-by-step explanation:

\frac{dy}{dx}= (x-2)(y-2)\\ y>2\\\frac{dy}{y-2}=(x-2)dx\\

integrate both side

<h2>∫\frac{dy}{y-2}=∫(x-2)dx\\</h2><h2>ln(y-2)=\frac{(x-2)^2}{2} +C\\</h2><h3>Substitute y(4)=5</h3><h3>ln3=2+C\\C=ln3-2</h3><h3>ln(y-2)=\frac{(x-2)^2}{2} +ln(3)-2\\y-2=e^{\frac{(x-2)^2}{2} +ln(3)-2}\\y=2+3e^{\frac{x^2}{2}-2x }</h3><h3 />

Investigate the difference between compounding annually and simple interest
Gennadij [26K]

Step-by-step explanation:

Simple interest formula

A = P (1 + rt)

Compound interest formula

A = P(1 + \frac{r}{n})^{nt}

a.

A = 5000 (1 + 0.025*1)\\A=5000(1.025)\\A=5125

Simple interest is $125

b

. A = 5000 (1 + \frac{0.025}{1})^{1*1}      \\A=5000(1.025)\\A= 5125

Compound interest is $125

c. the result for both a and b are the same

d.

A = 5000 (1 + 0.025*3) \\A=5000(1.075) \\A=5375

the simple interest is $375

e

. A = 5000 (1 + \frac{0.025}{1})^{1*3}] \\A=5000(1.025)^3 \\A=5000(1.077)\\A= 5385

the compound interest is $385

f. the result compared, compound interest is $10 more than simple interest

g.

A = 5000 (1 + 0.02*6) \\A=5000(1.12) \\A=5600

the simple interest is $600

h.

A = 5000 (1 + \frac{0.02}{1})^{1*6}] \\A=5000(1.12)^6 \\A=5000(1.9738) \\A= 9869

the compound interest is $4869

i. the result from g and h, h is over 8 times bigger than g.

j. interest compound annually is not the same as simple interest, only for the case of a and b seeing that it is for 1 year. but for 2years and above there is difference as seen in c to h

What is the y-intercept of the line?<br><br> y= -2x - 8<br><br> y-intercept =
ivolga24 [154]

Like I said on the other question. Slope will ALWAYS be the number beside x and y-intercept will always be after that.

Slope-intercept form = y = mx + b

Slope goes where m is and y-intercept goes where b is.

Hope this helps!

Please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!
Ksju [112]

Answer:

BF = 18

Step-by-step explanation:

In triangle BCD, H is the Centroid.

Centroid of a triangle divides the median in the ratio 2 : 1.

Therefore, BH : HF = 2 : 1

Let BH = 2x & HF = x

Since, HF = 6.... (given)

So, x = 6

2x = 2*6 = 12

BH = 12

Now,

BF = BH + HF = 12 + 6

BF = 18
