What is one third of the seventh whole number ?

Kitty [74]

We have to find one third of the seventh whole number.

Whole numbers is the set of numbers {0,1,2,3.....infinity}. This set starts from zero and it goes upto the infinity. Therefore, it is the set of integers or zero.

Firstly we will determine the seventh term of the whole number,

Since the first term of whole number is 0.

Second term is 1, third term is 2, fourth term is 3, fifth term is 4, sixth term is 5 and seventh term is 6.

Now, we will find one third of seventh whole number.

= $\frac{1}{3} \times 6$

=2.

Jacobs college savings are invested in a bond that pays an annual interest of 6.2% compounded continuously. How long will it tak

DiKsa [7]

Answer:

Therefore the value of bond will triple after 17.72 years.

Step-by-step explanation:

The formula of Compounded continuously

$A=Pe^{rt}$

A= Amount after t year

P= initial amount

r = rate of interest

t= time in year.

Given that,

Jacobs college saving are invested in bond that pay 6.2% compounded continuously.

Let after t years the initial amount P will be triple i.e 3P.

Here P=P, A=3P, r= 6.2%=0.062

$\therefore 3P=Pe^{0.062t}$

$\Rightarrow 3=e^{0.062t}$ [ Multiply $\frac 1P$ both sides]

Taking ln both sides

$\Rightarrow ln3=ln(e^{0.062t})$

$\Rightarrow ln3={0.062t}$ [ since $ln(e^a)=a$ ]

$\Rightarrow t=\frac{ln3}{0.062}$

$\Rightarrow t\approx 17.72$ years

Therefore the value of bond will triple after 17.72 years.

An epidemic follows the curve P=200/1+20,000e^-0.549^t million people, where t is in years. How fast is the epidemic growing aft

soldi70 [24.7K]

The equation is
P = 200 / (1 + 20000 e^-0.549t)
TO get the rate of epidemic growth, we differentiate the equation with respect to t
dP/dt = -200(1 + 2000 e^-0.549t)^-2 (20000)(-0.549)
Substitute t = 10 and you will get the epidemic growth rate after 10 years

Solve for u . <br><br> - 4u + 38 = 2(u-8)<br><br> Simplify your answer as much as possible.

zloy xaker [14]

Hi there!
Let's solve this equation step by step!

$- 4u + 38 = 2(u - 8)$
First work out the parenthesis, which can for instance be done using rainbow technique.

$- 4u + 38 = 2u - 16$
Subtract 2u from both sides.

$- 6u + 38 = - 16$
Subtract 38 from both sides.

$- 6u = - 54$
And finally divide both sides by -6, in order to isolate the variable u. Remember that dividing a negative by a negative gives a positive outcome.

$u = \frac{ - 54}{ - 6} = 9$
Hence, the answer is u = 9.
~ Hope this helps you!
