Answer:
a) 13913
b) 4913.82
Step-by-step explanation:
The compound interest formula is given by:

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.
In this question:
Investment of 9000, so 
Interest rate of 8%, so 
Compounded quarterly, so 
5 years and 6 months, that is, 5 years and half, so 
(a) How much would the value of her savings at the end of the term?


(b) How much is the interest earned by your savings?
The amount subtracted by the principal. So
13913.82 - 9000 = 4913.82
Answer:
33%
Step-by-step explanation:
The logo can be divided into three...
1. The inner circle (or The White Circle)
2. Blue + White circle
3. The whole circle(The logo)
I will be calculating the area of each circle..
Area of circle = (pi)r²
pi = 22/7
The inner circle
radius = 4cm
Area = 22/7 × 4²
= 50.286 cm² or 50²/7 cm²
Blue + White Circle
radius = 4 + 3 = 7cm
Area = 22/7 × 7²
= 154 cm²
The whole circle
radius = 4 + 3 +3 = 10cm
Area = 22/7 × 10²
= 314.286 cm² or 314²/7 cm²
Area shaded blue =
Area of [(Blue + White circle) - (The white circle)]
= 154 - 50.286 = 103.714 cm² or 103.⁵/7 cm²
Percentage of logo shaded blue =
(Area shaded blue) / (Area of logo) × 100
= 103.714/314.286 × 100
= 32.9999%
= 33%
X² + x + ...m
x² + x + 1/4
\/x² = x
\/(1/4) = 1/2
2*x*1/2 = 2x/2 = x
x² + x/2 + 1/4

a. 0.03 0.3 __________ 30 __________ __________
(3x + 1) + 44 = 90
(3x + 1) = (90 - 44) = 46
3x = 45
x = 45 / 3
x = 15
