In an investment account what if $2000 is invested. What is the value after 3 years if compounded monthly by 6% ?
OleMash [197]
<span>
Compound interest formula  A = P(1 +r/100)^n
A = Amount
r = rate = 6
n = number of compounding time.
P = Principal = $2000.
Since we are compounding monthly, r = 6% p.a = (6/12)% per month.
n= 3 years = 3*12 = 36 months.
Note that  since we are compounding monthly, our time would be in months.
A = P(1 +r/100)^n
A = 2000 * (1 + (6/12)/100 )^36
A = 2000 * (1 +  6/1200)^36
</span><span>A = 2000 * (1 +  0.005)^36    Use your calculator</span>
<span> <span>A = 2000 * (1 .005)^36</span> = 2393.36
Amount = $2 393.36</span>
That's it. Cheers.

If you have a density of 3g/ml and a volume of 10 ml, what is the mass?
balandron [24]

Alright, lets get started.

If you have a density of 3g/ml and a volume of 10 ml

means density = 3 g / ml

Volume = 10 ml

Formula for density, mass,  volume will be

density = \frac{mass}{volume}

Plugging the value

3 = \frac{mass}{10}

Multiplying 10 in both sides

10*3 = \frac{mass}{10} *10

mass = 30 gm

Hence the answer is 30 gm.   :    Answer

Hope it will help :)

4. Tests are performed to determine the Tool Life of a high speed steel single edge cutting tool. At a cutting speeds (v) of 180
podryga [215]

Answer:(a)   n=0.233

Step-by-step explanation:

Given

We Know according to Taylor tool life

VT^n=c

V=cutting speed

T=tool life

n=tool life exponent

c=constant

180\times \left ( 4.25\right )^n=110\times \left ( 35\right )^n

\frac{180}{110}=\left ( \frac{35}{4.25}\right )^n

1.636=\left ( 8.235\right )^n

taking log both side

\ln \left ( 1.636\right )=n\ln \left ( 8.235\right )

n=0.233
