Answer:
Only A is not Pythagorean Identity.
Step-by-step explanation:
Let us draw a unit circle as shown in the attached figure.
In the given figure, let us apply Pythagorean theorem, which is given by
Divide both sides by
Divide both side of identity C by
Therefore, only A is not Pythagorean Identity.
69 - 3a = 0
69 - 3a (-69) = 0 (-69)
-3a = -69
-3a(/-3) = -69(/-3)
a = 23

Hello,
f(x)=x^2+9
1) f(-3)=(-3)^2+9=9+9=18
2) f(x-2)=(x-2)^2+9=x^2-4x+4+9=x^2-4x+13
First simplify the square roots.
√25 is 5 and √16 is 4
so the equation is 3x5 + 4x4
15+16
31
