Answer:
<h2>9 × (10 + 3)</h2>
Step-by-step explanation:
The distributive property:
<em>a × (b + c) = a × b + a × c</em>
90 = 9 × 10
27 = 9 × 3
90 + 27 = 9 × 10 + 9 × 3 = 9 × (10 + 3)
We Know that
For a function to have an inverse function, it must be one-to-one—that
is, it must pass the Horizontal Line Test.
1. On the interval [–pi/2, pi/2], the function
y = sin x is
increasing
2. On the interval [–pi/2, pi/2], y = sin x takes on its full
range of values, [–1, 1]
3. On the interval [–pi/2, pi/2], y = sin x is
one-to-one
sin x has an inverse function
on this interval [–pi/2, pi/2]
On the restricted domain [–pi/2, pi/2] y = sin x has a
unique inverse function called the inverse sine function. <span>f(x) = sin−1(x)
</span>the range of y=sin x in the domain [–pi/2, pi/2] is [-1,1]
the range of y=sin-1 x in the domain [-1,1] is [–pi/2, pi/2]
1. On the interval [0, pi], the function y = cos x is decreasing
2. On the interval [0, pi], y = cos x takes on its full range of values, [–1, 1]
3. On the interval [0, pi], y = cos x is one-to-one
cos x has an inverse function on this interval [0, pi]
On the restricted domain [0, pi] y = cos x has a unique inverse function called the inverse sine function. f(x) = cos−1(x)
the range of y=cos x in the domain [0, pi] is [-1,1]
the range of y=cos-1 x in the domain [-1,1] is [0, pi]
the answer is
<span>the values of the range are different because the domain in which the inverse function exists are different</span>

Answer:
31 ft
Step-by-step explanation:
Let the Woman's Eye level be at Band the top of the statue be at C in the attached diagram.
We want to calculate the height CE of the statue.
CE=CD+DE
First we find CD using trigonometry
Tan 60=CD/15
CD=15 X Tan 60
=25.98 ft
DE=AB= 5ft( Sides of a Rectangle)
Therefore the height of the statue
CE=CD+DE = 25.98+5=30.98 ft
=31ft( to the nearest foot)
