Please help!
blagie [28]
Given the two options above, in order to come up with the best plan we have to calculate the future value of money in each plan.
compound interest is given by:FV=p(1+ \frac{r}{100})^n

Option 1
p=$500
r=2%=0.02
t=1 year
FV=500(1+0.02)^1=$510

Option 2
p=$500
r=2/12=1/6
n=1*12=12
hence:
FV=500(1+\frac{ \frac{1}{6}}{100})^{12}

=$509.09
Comparing the two plans above, option 1 is the best.

b] Option 1 is the best because she will secure $510 as compared to option 2 which has interest rate that reduces her amount by $1 after one year due to annual charges. The total amount of money she will have at the end of the plan is $510.

∫c<br> x sin y ds, C is the line segment from (0, 1) to (3, 5)
Mnenie [13.5K]
Parameterize the line segment C by

\mathbf r(t)=\langle x(t),y(t)\rangle=(1-t)\langle0,1\rangle+t\langle3,5\rangle=\langle3t,1+4t\rangle

where t\in[0,1]. Then

\mathrm ds=\|\mathbf r'(t)\|\,\mathrm dt
\mathrm ds=\|\langle3,4\rangle\|\,\mathrm dt
\mathrm ds=5\,\mathrm dt

So the integral is

\displaystyle\int_Cx\sin y\,\mathrm ds=5\int_0^1x(t)\sin y(t)\,\mathrm dt
=\displaystyle5\int_0^13t\sin(1+4t)\,\mathrm dt
=\dfrac{15}{16}(\sin5-\sin-4\cos5)\approx-2.7516

Find the product or quotient for each. simple form<br> 5/9 divide 5/6
MakcuM [25]

Answer: 2/3

Step-by-step explanation:

5/9 and 5/6 doesn't have the same denominator. So 5/9 changes to 10/18, while 5/6 changes to 15/18.

10/18 divided by 15/18= 10/18 x 18/15 = 180/270

180/270= 2/3
