Answer:

5 units

Step-by-step explanation:

Length AB,

Just apply the formula;

Length between two points =square root of [(difference in x coordinates)^2 + (difference in y coordinates)^2]

Length AB =square root of [(4 - 7)^2 + (-5 - - 9)^2]

Length AB =square root of [ (-3)^2 + (4)^2]

Length AB = square root of (25)

Length AB = 5 units

Y=Cosx.arcsinx What is the solution

Alinara [238K]

Step-by-step explanation:

Given: $y = cos(sin^{-1}x))$

As the domain for the inverse sine function is 1 ≤ x ≤ 1 as this is the range for the sine function.

The range for the function is the same as the range for the cosine function, 1 ≤ y ≤ 1

$sin^{2}x +cos^{2}x = 1$

So, using the identity $cos(x) = \pm \sqrt{1-sin^{2}(x) }$

$y = \pm \sqrt{1-sin^{2}(sin^{-1}(x)) }$

As the sin and inverse sin function do cancel each other, so only x² is left.

Hence,

$y = \pm \sqrt{1-x^{2}$ ; $-1\leq x\leq 1$
