Given:
V = 5x² + 15x + 2, the volume
h = 5x, the height
Let A = the area of the base.
Because V = Ah, therefore
A*(5x) = 5x² + 15x + 2
Answer:
Answer:
2
Step-by-step explanation:
The tangent is positive in quadrants I and III. There are two angles with that tangent value:
33.96° and 213.69°
Answer:
y = 18 when x = 3
Step-by-step explanation:
y is directly proportional to x^2, meaning:
where a is the proportion between them. We're given the values for both x and y, so plug those in and solve for a:
Now you can use a to solve for y when x is 3:
Domains of functions are the values that <em>can</em> be plugged into the function and not "break" it. By "break" I mean that the denominator cannot be 0, in this case. If the denominator is 0, we will get a divide by 0 error, and thus, we must restrict the domain. All values of x will work except 9/4:
Let's plug in 9/4 and see what happens:
So, plugging in 9/4 results in denominator equalling 0. Therefore, we must restrict the domain so that x ≠ 9/4. Your answer is All real values of x such that x ≠ 9/4.
