Answer:

Total amount in Joe's savings account T = $448

Step-by-step explanation:

Given;

time t = 3 years

Annual rate r = 4%

Principal P = $400

Simple interest can be expressed as;

I = Prt/100

Substituting the given values;

I =400×4×3/100 = 4800/100

I = $48

Total amount in account T;

T = P + I = $400 + $48 = $448

Answer:

$448

Step-by-step explanation:

To calculate Joe's savings, we can use the formula for simple interest:

P = Po*(1+r*t)

Where P is the final value, Po is the inicial value, r is the interest and t is the time in years.

So, In our problem, we have that Po = 400, r = 4% and t = 3, then we can find P:

P = 400*(1+0.04*3)

P = 400*1.12 = $448

Joe has $448 in his savings.

Let c\in(0,\infty). Then the definite integral can be split up at t=c so that

\displaystyle F(x)=\int_{t=2x}^{t=5x}\frac{\mathrm dt}t
\displaystyle=\int_{t=2x}^{t=c}\frac{\mathrm dt}t+\int_{t=c}^{t=5x}\frac{\mathrm dt}t
\displaystyle=-\int_{t=c}^{t=2x}\frac{\mathrm dt}t+\int_{t=c}^{t=5x}\frac{\mathrm dt}t

Now take the derivative. By the fundamental theorem of calculus, you have

\displaystyle\frac{\mathrm dF}{\mathrm dx}=\frac{\mathrm d}{\mathrm dx}\left[\int_{t=c}^{t=5x}\frac{\mathrm dt}t-\int_{t=c}^{t=2x}\frac{\mathrm dt}t\right]
=\displaystyle\frac1{5x}\dfrac{\mathrm d}{\mathrm dx}[5x]-\frac1{2x}\dfrac{\mathrm d}{\mathrm dx}[2x]
=\dfrac5{5x}-\dfrac2{2x}
=\dfrac1x-\dfrac1x
=0

Then integrating with respect to x, we recover F(x) and find that

\displaystyle\int\dfrac{\mathrm dF}{\mathrm dx}\,\mathrm dx=\int0\,\mathrm dx
F(x)=C

where C is an arbitrary constant.

Bills video files take up 15 gigs of space on his hard drive about how many bytes is that
Citrus2011 [14]
1 gig is 1,000,000,000 bytes.
We can do 15 times 1,000,000,000 to get 15,000,000,000.

So your answer is 15,000,000,000 gigs.
