3.3^2 means 3.3 times itself 2 times or 3.3 times 3.3 or (use calculator)10.89
smaller powers (that's what 3.3^2 is, it means 3.3 to the second power) sometimes use different words to denote powers exg
x^2=x squared (square=2dimentionsl)
x^3=x cubed (cube=3 dimentionsl)
then x^4=x to the fourth, and so on
fifth, sixth, tecnth
Answer:
129.3 in²
Step-by-step explanation:
The shaded segment is calculated as
area of sector ABC - area of triangle ABC
area of sector = area of circle × fraction of circle
A = πr² × 
= π × 18² × 
= 324π × = 54π in²
area of Δ ABC = 
× 18 × 18 × sin60° ≈ 40.30 in²
Then
shaded area = 54π - 40.30 ≈ 129.3 in² ( to the nearest tenth )
8 would be the coefficient :)
D=dimes
q=quarters
if she has 12 coins then
12-d=q she has 12-d quarters
we dont know how much money she has unless we know d.
she could have 12 dimes and 0 quarters or 11 dimes and 1 quarter etc. we need more information to solve.
Answer:
9 square root of 2 or 12.73
