2 is Reflexive property
4 is (I don't remember the specific property of this)
Answer:
Variance s2 = 788.33333
Standard Deviation s = 28.077274
Count n = 7
Mean x¯¯¯ = 52
Sum of Squares SS = 4730
Step-by-step explanation:
Next time use the desmos calculator online and input the numbers.
The answer to this equation is:
y = (x - 3)^2 - 2
Answer with Step-by-step explanation:
We are given that:
tanA = 0.45
tanA=
=
⇒ =0.45
⇒ =
⇒ =
⇒ AC= 20
Hence, by pythagoras theorem
AB²=AC²+BC²
AB²=20²+9²
AB²=481
⇒ AB=21.9 units
Hence, the approximate length of AB is:
22 units
