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.

A sphere of radius 7 in. Is placed inside a rectangular prism with length 15 in., width 18 in., and height 20 in. What is the vo
iragen [17]

Answer:

3964 in³

Step-by-step explanation:

volume of sphere:  V = 4/3 πr³

v₁ = 4/3 x 3.14 x 7³ = 1436

volume of prism: v = Bh     B = 15 x 18 = 270    h = 20

v₂ = 270 x 20 = 5400

v₂ - v₁ = 5400 - 1436 = 3964 in³

HELP!Write the equation of the line fully simplified slope-intercept form.
xxTIMURxx [149]
Find slope first
Two points: (-5,-2) and (5,4)
(4+2)/(5+5) = 6/10 = 3/5 slope
So far: y = 3/5x + b
Plug in any of the point
-2 = 3/5(-5) + b, b = 1
Final equation: y = 3/5x + 1
