Banabas must pay his ex-wife an amount of R350 000 in two years’ time. Calculate the amount that he must invest today to have th

White raven [17]

Answer:

He must invest R297 521 today.

Step-by-step explanation:

The compound interest formula is given by:

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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Banabas must pay his ex-wife an amount of R350 000 in two years’ time.

This means that $t = 2, A(t) = 350000$

Interest rate of 8.15% per annum compounded monthly:

This means that $r = 0.0815, n = 12$ .

Amount he must invest today:

This is P. So

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

$350000= P(1 + \frac{0.0815}{12})^{2*12}$

$P = \frac{350000}{(1 + \frac{0.0815}{12})^{2*12}}$

$P = 297521$

He must invest R297 521 today.

Is this a function or not

Marta_Voda [28]

Answer:

No, I don't think so.

Step-by-step explanation:

I don't think this is a function because the triangle is made of multiple points. Some of these points share the same <em>x</em> point, so this concludes that a triangle on a graph is not a function.

Hope it helps!

Square measures 8 m on each side if each side is written by 1/4 of eight originally the premiere of the new square will be blank

Digiron [165]

Step-by-step explanation:

so, if I understand this correctly, the original square had a side length of 8 m.

now we transform this square into one with side length 1/4×8 = 8/4 = 2 m.

and the questions are what are the perimeter and the area of that new (smaller) square ?

the perimeter of a square is

4× side length = 4×2 = 8 m

the area of a square is

side length ² = 2² = 4 m²
