Knowing that your area is: A= \pi  r^{2}=36  in^{2} you can find the radius as:
r= \sqrt{ \frac{36}{ \pi } } =3.4 in;
With this you can evaluate the circumference as:
C=2 \pi r=2*3.14*3.4=21.3 in

if £5000 Is placed into a bank account that pays 2% compound interest per year, how much will be in the account after two years
timurjin [86]

Answer:

£5200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 5000 × 0.02 × 2 = 200

I = £ 200.00

The simple interest accumulated

on a principal of £ 5,000.00

at a rate of 2% per year

for 2 years is £ 200.00.

Answer: a) 6, 0, 10       b) yellow/orange line  

Step-by-step explanation:

a) Plug the x in the y functions, y = 2x² + x

when x = -2, y = 2(-2)² + (-2) = 8 - 2 = 6

when x = 0, y = 2(0)² + (0) = 0 + 0 = 0

when x = 2, y = 2(2)² + (2) = 8 + 2 = 10

b) By looking the table, the equation has a point (0,0), only blue and yellow/orange line has the passed the point (0,0), so we delete the red line option.

And we choose a point (1,3), then only yellow/orange line has passed the point (1,3). So the yellow/orange line fits the equation.
