Sindi borrowed an amount of money from his
PolarNik [594]

The present value of the loan is R576923.

<h3>What is compound interest ?</h3>

Compound interest is giving the current instalment in terms of the total previous amount.

The formula is given by

A = P(1 + r/100)ⁿ.

Where,

A = Amount, P = Principle, r = rate of interest, n = Time in years.

In case the compound if interest is given every two months that is 6 instalments each year the above given formula will be

A = P{ 1 + (r/6)/100 }⁶ⁿ.

According to the given question

Rate(r) = 7.5%

Time(n) = 6 years

The loan will be paid back in 6 years every second month and it is compounded.

∴ No. of instalments = (12 × 6)/2

= 36.

Now each instalments is of R25000

So, The total amount she has to pay back to his father is

= (25000 × 36)

= R900000.

We know compounding every two months is

A = P(1 + r/100)ⁿ

900000 = P{ 1 + (7.6/6)/100 }³⁶

900000 = P{ 1 + 1.25/100 } ³⁶

900000 = P(1.0125)³⁶

900000 = 1.56P

∴ P = 576923.

mr_godi [17]

Answer:

31°

Step-by-step explanation:

The upper and lower triangles are similar, because their bases are parallel.

This implies that their correspondent angles have the same measure: the correspondent angle of x is the 31° angle.

Find a polynomial, which, when added to the polynomial 5x^2–3x–9, is equivalent to <br><br> x^2-5x+6
alexandr1967 [171]
So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9

wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2

then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x

-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15

Y= 1/2x + 2 <br> Select points on the graph
Cloud [144]

Step-by-step explanation:

—x intercept, y = 0

y = 1/2 x + 2

0 = 1/2 x + 2

-2 = 1/2 x

-2.2 = x

-4 = x

X intercept = (-4 , 0)

—y intercept, x = 0

y = 1/2 x + 2

y = 1/2 . 0 + 2

y = 0 + 2

y = 2

Y intercept = (0 , 2)

Graph in the picture :)
