What is the value of K? k=___​

Mathematics
2 answers:
Anestetic [448]4 years ago
8 0

Answer:

Step-by-step explanation:

In triangle LON, <O = 90°

According to Pythagoras' Theorem

(Hyp)² = (Base)² + (Perp)²

m² = 4² + 8²

m² = 16 + 64

m² = 80

Taking square roots on both sides

√m² = √80

m = 8.94

In triangle LMN, <N = 90°

According to Pythagoras' Theorem

(Hyp)² = (Base)² + (Perp)²

(8 + k)² = l² + 4²

Ok, this definition of f is just a bunch of points (4 to be exact).

so if point (a,b) is part of f, then f(a)=b

f(1) is about point (1,0), so f(1)=0.
g(1) = 1 (due to point (1,1))
g(2/3) = 0
f(2) = 3/4
g(-2) = 3
f(π) = -2

just a lookup once you see what is happening
