Answer:
the answer is c
Step-by-step explanation:
2t(2 + r + 4s)
Area = PI x r^2
r = 1/2 d = 1/2* 4.1 = 2.05
2.05^2 = 4.2025
answer is 4.2025PI m^2
Answer is D
Answer by JKismyhusbandbae: So this is really simple. You are probably making this out harder than it needs to be. Consider the set of ordered pairs {(-1,0), (4,-5), (6,-6), (9,11), (10,14)}. This set of ordered pairs is a function because for each value of x there is one and only one y-value. This means that the x value never repeats. Therefore any function is a function when the x value never repeats.
Looking at the table we want to find all it's ordered pairs: (0,4), (1,2), (2,3), (3,9), (4,1).
F(2) is 3 so when x equals 2.
So the ordered pair is (2,3) 2 is the x value and the f(2) is 3.
It’s not minus 1 it’s plus 1 poopoo head
