PLEASE HURRY write the equation of the inverse function y=1/2cos^-1(pix)-3

Step-by-step explanation:

Firstly, we've to interchange the variables.

Solving for y

Adding 3 to both sides

Multiplying 2 to both sides

Taking cosine on both sides

Dividing both sides by y

Replace y by

=>

Step-by-step explanation:

Swicth variables.

Solve for y.

Add 3 to both sides.

Multiply both sides by 2.

Take the cos of both sides.

Divide both sides by .

(x, y)→(x − 8, y − 7)

step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
