Answer:
<h2>(2,4)</h2>
Step-by-step explanation:
The given function is
Where , and .
The vertex is at , which is defined as and . So, replacing values, we have
Then,
So, the vertex is at .
Remember that the minium or maximum value of a quadratic function is defined by its vertex. In this case, it represents a minimum at (2,4).
Answer:
-43
Step-by-step explanation:
just plug in -9 for x and solve
g(-9)=4(-9)-7
=-43
So if u were to use a calculator, which you probably might need, you would take the radius, square it by 3, multiply by 4 and then divide by 3.
Answer:
The answer its C
Step-by-step explanation:
The first and second number equals 18.
The second number times two plus three gives you the first number.
Rationalizing the denominator involves exploiting the well-known difference of squares formula,
We have
so that
Rewrite 16 and 32 as powers of 2, then simplify:
So we have <em>A</em> = 8, <em>B</em> = 2, <em>C</em> = 4, and <em>D</em> = 7, and thus <em>A</em> + <em>B</em> + <em>C</em> + <em>D</em> = 21.
