BGC = 90 degrees = PGC + BGP
PGC = 37 degrees
90 = 37 + BGP
Subtract 37 from both sides
53 = BGP
g(x) = x - 4
g₀f (x) = g(f(x))
g₀f (0) = which is undefined.
Hence g₀f (0) can't be evaluated.
9 and 7 would be corresponding angles,
6 and 3 would be alternate interior angles,
5 and 4 should be same-side interior angles,
and the only exterior angle is 9.
I hope that helps.
-2^4
= -2^4
= 1 * 2^4
= -1 * (2 * 2 * 2 * 2)
= -16
your answer is -16 for sure.
btw * means multiplication
I'm assuming you meant to write a^4 = 625.
If that is the case, then note how 625 = 25^2, and how a^4 is the same as (a^2)^2
So we go from this
a^4 = 625
to this
(a^2)^2 = 25^2
Apply the square root to both sides and you'll end up with: a^2 = 25
From here, apply the square root again to end up with the final answer: a = 5 or a = -5
As a check:
a^4 = (-5)^4 = (-5)*(-5)*(-5)*(-5) = 25*25 = 625
a^4 = (5)^4 = (5)*(5)*(5)*(5) = 25*25 = 625
Both values of 'a' work out
