you want to put $4000 in a simple interest account. it has a 2.5% annual interest rate. how long will it take you to earn $500 i

yaroslaw [1]

T=I/Pr
t:500/(4000*0.025)
t: 5 yrs
Dear Random17, the question to your answer requires the use of the formula I=Prt. The equation will look like 500=4000(0.025)t. Multiply 4000 times 0.025 to get 500=10t. T=50 years.

Find the amount of money accumulated if you invested $25,000 at 4.3% interest for 8 years compounded continuously .

MArishka [77]

The appropriate formula for the accumulated amount (A) for a given principal (P), interest rate (r), and time period (t) is ...

... A = P·e^(rt)

Filling in the given numbers and doing the arithmetic, we get

... A = $25,000·e^(.043·8) ≈ $35,264.46

Find a closed-form solution to the integral equation y(x) = 3 + Z x e dt ty(t) , x > 0. In other words, express y(x) as a fun

MrMuchimi

Answer:

$y{x} = \sqrt{7+2Inx}$

Step-by-step explanation:

$y(x)= 3 + \int\limits^x_e {dx}/ \, ty(t) , x>0}$

Let say; By y(x)= y(e)

we have;

$y(e)= 3 + \int\limits^e_e {dt}/ \, ty= 3+0$

Using Fundamental Theorem of Calculus and differentiating by Lebiniz Rule:

$y^{1} (x) = 0 + 1/ xy$

$y^{1} = 1/xy$

dy/dx = 1/xy

$\int\limits {y} \, dxy = \int\limits \, dx/x$

$y^{2}/2 Inx + C$

RECALL: y(e) = 3

$(3)^{2} / 2 = In (e) + C$

$\frac{9}{2} =In(e)+C$

$\frac{9}{2} - 1 = C$

$\frac{7}{2} = C$

$y^{2} / 2 = In x +C$

$y^{2} / 2 = In x +7/2$

MULTIPLYING BOTH SIDE BY 2 , TO ELIMINATE THE DENOMINATOR, WE HAVE;

$y^{2} = {7+2Inx}$

$y{x} = \sqrt{7+2Inx}$

What was the total production of gasoline and kerosene combined (in Barrels)

Elina [12.6K]

The amount of kerosene and gasoline produced is an illustration of equations.

<em>44.4 million barrels of gasoline and kerosene are produced</em>

Let

<em /> $x \to$ <em> Proportion of kerosene</em>

<em /> $y \to$ <em> Proportion of Gasoline</em>

<em />

So:

$x = 40\%$

$y = 34\%$

$Total = 60\ million$ ---- total barrels produced

The amount of Kerosene produced is:

$Kerosene =x \times Total$

$Kerosene =40\% \times 60\ million$

$Kerosene = 24\ million$

The amount of Gasoline produced is:

$Gasoline =y \times Total$

$Gasoline =34\% \times 60\ million$

$Gasoline =20.4\ million$

So, the total production of both is:

$Total = Kerosene + Gasolene$

$Total = 24\ million + 20.4\ million$

$Total = 44.4 million$

<em>Hence, 44.4 million barrels of gasoline and kerosene are produced</em>
