Cosine = adjacent ÷ hypotenuse

So the cosine of ∠y would equal 64/80
64 being the adjacent side
And 80 being the hypotenuse

cos(y) = 64/80 = 4/5

The answer would be 4/5 or 80°

The cosine of angle y would be equal to the length of the adjacent side over the length of the hypotenuse.

cos(y) = $\frac{64}{80}$ = $\frac{4}{5}$

False.

intersects the y-axis => x=0

If (x/100-1)(x/100+1)=kx^2-1 k=

Artist 52 [7]

(x/100-1)(x/100+1)=kx^2-1
(x/100-1)(x/100+1)=(x/100)^2 - 1^2 because it's a difference of squares ( (a-b)(a+b) = a^2-ab+ab-b^2 = a^2 - b^2):
(x/100)^2 - 1^2=kx^2 - 1
(x/100)^2 - 1=kx^2 - 1
(x/100)^2=kx^2
(x^2)/(100^2)=kx^2
1/(100^2)=k
1/10000=k
k=0.0001
