"a "and "b^2-4ac" must be negetive
Answer:
xy
Step-by-step explanation:
Let's take a look at what factors and have in common.
is composed of and y, and is composed of x and . Notice that both x and y are factors of them, so the gcf is xy.
A = (√3)/4 x s²
s = 9
A = (√3)/4 x 9²
A = (√3)/4 x 81
A = (81√3)/4
Answer:
B
y = 3 cos (pi/12x - pi/4) + 17
Step-by-step explanation:
First find the average temperature which is 20 + 14/2 = 17
Find the amplitude
20 - 17 = 3
This means that that at noon, the shift is 3hrs past
the best equation that represents this scenario is
