Answer:
She has descended a total of 18 feet from the top to her friend.
Step-by-step explanation:
Anna is 26 ft. high on a rock-climbing wall.

Then climbs down until she reaches her friend, who is 8 feet from the ground.
So, she climbs down feet more.
Hence, in total Anna has descended feet

Answer:
The domain that makes sense for this function is all values greater than or equal to 0.
Step-by-step explanation:
A ball is thrown into the air from a height of 4 feet at time <em>t</em> = 0. It is modeled by the function:
The domain of the function is time <em>t</em>. The range of the function is the ball's height in the air <em>h</em>.
Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.
Therefore, the domain that makes sense for this function is all values greater than or equal to 0.
In interval notation, this is:
And as an inequality:
