Difference means subtraction and a number means a variable so
5x-10=0 5 times a number is 5x and difference is subtraction to 10 so 5x-10 and the word is means equals.

One side of a triangle is increasing at a rate of 9 cm/s and a second side is decreasing at a rate of 2 cm/s. if the area of the
LenKa [72]
Use the attached figure to guide yourself through the explanation. In the figure:
a=21cm, b=36cm, \widehat{C}=\frac{\pi}{6}.
We know that:
 \frac{da}{dt}=9,\frac{db}{dt}=-2
Also remmeber that the area of a triangle is:
A=\frac{Base\times Height}{2}
The hegiht is shown in the figure in red, the base is just the b side.
Using the angle C the area of the triangle is:
A=\frac{1}{2}ab\cos(\widehat{C})\implies2A=ab\cos(\widehat{C})
Now taking the derivative of the area 2A with respect to t we have:
2\frac{dA}{dt}=b\cos(\widehat{C})\frac{da}{dt}+a\cos(\widehat{C})\frac{db}{dt}-ab\sin(\widehat{C})\frac{d\widehat{C}}{dt}

Replacing with the right values:
\frac{dA}{dt}=0\\&#10;\\&#10;\cos({\widehat{C}})=\frac{\sqrt{3}}{2}\\ \\&#10;\sin({\widehat{C}})=\frac{1}{2}\\ \\&#10;&#10;
yields:
0=36\frac{\sqrt{3}}{2}.9-21\frac{\sqrt{3}}{2}.2-\frac{1}{2}.21.36.\frac{d\widehat{C}}{dt}\implies \frac{d\widehat{C}}{dt}=\frac{141}{378}\sqrt{3}

You have $500,000 saved for retirement. Your account earns 8% interest. How much will you be able to pullout each month, if you
borishaifa [10]

The rule of the payout annuity is

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

P is the initial amount

d is regular withdrawals

r is the annual rate in decimal

n is the number of periods in a year

t is the time

Since you have $500 000 saved, then

P = 500000

Since the interest is 8%, then

r = 8/100 = 0.08

Since the time is 15 years, then

t = 15

Since you want the monthly amount, then

n = 12

Substitute them in the rule to find d

\begin{gathered} 500000=\frac{d(1-(1+\frac{0.08}{12})^{-12(15)})}{\frac{0.08}{12}} \\ 500000(\frac{0.08}{12})=d(1-(\frac{151}{150})^{-180}) \\ \frac{10000}{3}=d(1-(\frac{151}{150})^{-180}) \\ \frac{\frac{10000}{3}}{(1-(\frac{151}{150})^{-180})}=d \\ 4778.260422=d \end{gathered}

Then you will be able to pull $4778.260422 each month
