Calculate the future value of $500.20, earning interest at a rate of 3 7/8% that is compounded monthly for 4 years.

KATRIN_1 [288]

Answer:

584.03

Step-by-step explanation:

Given that principal amount = 500.20 dollars

Interest rate = 3 7/8% p.a.= 3100/8(12) per month

Period = 4 years = 4(12) = 48 months.

A= P(1+r/n)^nt

Here n = 12 t = 4 years.

Substitute to get

Future value = $500.20(1+\frac{32}{8(1200)} )^{48}$

=584.03

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
