Use the appropriate compound interest formula to compute the balance in the account after the stated period of time 24,000 is in
VLD [36.1K]

We know the compound interest formula is given by

A=P(1+\frac{r}{n} )^{nt}

Now, we have been given that 24,000 is invested for 2 years with an APR of 6​% and daily compounding. Thus, we have

P= 24,000\\
\\
t=2\\
\\
r=0.06\\
\\
n=365

On substituting these values in the above formula for the compound interest, we get

A=24000\left ( 1+\frac{0.06}{365} \right )^{365\cdot 2}\\
\\
\text{On solving this, we get}\\
\\
A=27059.7

Therefore, the balance in the account after 2 years is 27059.7

I need help with these questions
natali 33 [55]

Answer: 1/3 = 33.3% or 33 ⅓%

1/9 = 11.1%

2/9 = 22.2%

8/9 = 88.9%

Step-by-step explanation:

Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.

All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.

Rom4ik [11]

Answer:

100,000C999

Step-by-step explanation:

Given that the Martian Colonies elect their government through a lottery. There are 100,000 people living on Mars

every year, a council of 99 co-equal leaders is randomly selected from the population.

Since these are members, order of selection of not important

So combinations woul dbe used here.

Total number of persons avaiiable = 100,000

No of persons to be selected = 999

No of ways this can be done =

999 out of 100,000

= 100,000C999

Los puntos de intersección de los gráficos de f(x)=x2+6x−7 y g(x)=4x−10
alisha [4.7K]

Answer:

Those graphs do not intersect.

Estes gráficos no se intersecciónan

Step-by-step explanation:

The intersection points are x for which:

f(x) = g(x)

In this question:

f(x) = x^{2} + 6x - 7

g(x) = 4x - 10

So

x^{2} + 6x - 7 = 4x - 10

x^{2} + 2x + 3 = 0

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

In this question:

x^{2} + 2x + 3 = 0

So a = 1, b = 2, c = 3

\bigtriangleup = b^{2} - 4ac = 2^{2} - 4*1*3 = -8

Sincce \bigtriangleup is negative, there are no solutions, which means that those graphs do not intersect.
