<h3>Function Notation</h3>
The function is given as:

The interpretation when Steven is asked to calculate Blue(s + h) is that:
Steven is asked to find the output of the function Blue, when the input is s + h
So, we have:

Evaluate the exponent

Expand the bracket

So, the correct work is:

<h3>Simplifying Difference Quotient</h3>
In (a), we have:


The difference quotient is represented as:

So, we have:

Evaluate the like terms

Evaluate the quotient

Hence, the correct work is:

Answer:
Answer down below :)
Step-by-step explanation:
The volume of the rectangular prism is:
20 x 9 = 180cm^2
The volume of the triangular prism is
6 x 9 x 1/2 = 27cm^2
I'm sorry, that is all I can do, but the total volume would be 180 + 27 + the cylinder's volume. Have a nice day :)
Answer:

Step-by-step explanation:
The submersible is diving at a down angle of 15° along the hypotenuse AC of triangle ABC.
Its horizontal track along the surface AB is 1500 ft.

The submersible was already at a depth of 250 feet when it began the dive.
New depth = 250 + 402 = 652 ft

Answer:
10s^2-15s+20
Step-by-step explanation:
<em> because 5(2s^2)=10s^2, 5(-3s)=-15s, and 5(4)=20</em>
<em>hope it helps:)</em>
Answer:
The given polynomial is,
2x³+5x²-8x-10=0
all possible roots of a polynomial,
ax³+b²+c x +d=0 ← all possible factors of ration (d/a)
Therefore, eq (1), all possible factors are the factors of ratio (-10/2)
which are, B) { ± 1, 1/2, ± 2, ± 5/2, ±5, ± 10}
