Answer:

Step-by-step explanation:

Yellow Circle:

9+2.5 = 11

2 x pi x 11= 69.115

Nearest hundredth = 69.12

Purple Circle:

9 divided by 2 = 4.5

2 x pi x 4.5 = 25.1327

Nearest hundredth = 25.13

Answer:

10

Step-by-step explanation:

Use the distance formula.

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We have x1 = 2; y1 = 0; x2 = -6; y2 = 6.

d = \sqrt{(-6 - 2)^2 + (6 - 0)^2}

d = \sqrt{(-8)^2 + 6^2}

d = \sqrt{64 + 36}

d = \sqrt{100}

d = 10

Calculate the annual return percentage
const2013 [10]
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%

b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
