Answer: A, D
Step-by-step explanation:
68 is the initial amount.
A is correct because 0.2(68) represents 20% of 68. Since you're looking for 80% of 68, you subtract 0.2(68) from 68.
D is correct because it directly takes 80% of 68, which is what the question is asking for.
i believe it’s D because where you have 20 marked it’s 20 more from where you are which would be around 40 which is why i’m saying D
rounding 0.0692494 to 3SF is 0.069
Answer:
B the parent function is periodic
Step-by-step explanation:
We can see from the graph that
A it is a polynomial
C that is has 3 real root ( where it crosses the x axis)
D that is contains the point (0,-20)
What is not true is that it is periodic. That would mean it repeats after a certain time.
Answer:
Step-by-step explanation:
x^2 = (49/100)
x = (7/10) and -(7/10)
If x = (7/10), then x^2 = 49/100
If x = -(7/10), then x^2 = 49/100
