The area is 50.24 cm.
The formula is π·r^2.
The radius is 4 cm, and you square it. 16 cm.
Then you multiply 16 by 3.14 (π). And you get 50.24 cm as the area.

Calculate the total amount and compound interest on RS 8,000 for a year at the rate of 9% per annum compounded half yearly.

Gennadij [26K]

Answer:

See below in bold.

Step-by-step explanation:

Total = A(1 + r/n)^nt where A = initial amount , t = number of years, r = the rate (as a decimal fraction) and n = number of payments a year. So:

Total after 1 year = 8000(1 + 0.09/2) ^ 1*2

= RS 8736.20.

Compound interest = RS 736.20

What is the value of A when we rewrite 2^x-6 + 2x as A * 2^x?

Leto [7]

Algebraic expressions are expressions that use numbers and variables

The value of A is 65/64

<h3>How to determine the value of A</h3>

The expression is given as:

$2^{x - 6} + 2^x$

Rewrite the expression as:

$2^{x - 6} + 2^x = \frac{2^x}{2^6} + 2^x$

Factor out 2^x

$2^{x - 6} + 2^x = 2^x(\frac{1}{2^6} + 1)$

Rewrite as product

$2^{x - 6} + 2^x = 2^x * (\frac{1}{2^6} + 1)$

The expression to compare with is given as: A * 2^x.

So, we have:

$A * 2^x =2^x * (\frac{1}{2^6} + 1)$

Divide both sides by 2^x

$A =\frac{1}{2^6} + 1$

Take LCM

$A =\frac{1 + 2^6}{2^6}$

$A =\frac{65}{64}$

Hence, the value of A is 65/64

A right angle = 90 degrees

A round angle = 360 degrees

1. 3 x 90 = 270 degrees

2. 4 x 90 = 360 degrees

3. 1 1/2 x 90 = 135 degrees

4. 2 1/3 x 90 = 210 degrees

5. 2/9 x 360 = 80 degrees

6. 3 3/8 x 360 = 1,215 degrees
