Answer:

Step-by-step explanation:
So we have the function:

To solve for the inverse of a function, change f(x) and x, change the f(x) to f⁻¹(x), and solve for it. Therefore:

Add 9 to both sides:

Take the natural log of both sides:

The right side cancels:

Divide both sides by 6:

And we're done!
Answer:
4.243
Step-by-step explanation:
To calculate the diagonal of a square, multiply the length of the side by the square root of 2:
d = a√2
d = 3√2=4.24264068
See the picture attached to better understand the problem
we know that
m ∠ACD=91.5°
m ∠ACD+m ∠ACB=180°-------> by supplementary angles
so
m ∠ACB=180-91.5-----> m ∠ACB=88.5°
m∠CAB+m ∠ACB=90°-----> by complementary angles
so
m ∠CAB=90-88.5-----> 1.5°
m∠ CAB is <span>the new angle at the bottom left side of the door
the answer is1.5</span>
