Answer:
A ≈ 28.27
Step-by-step explanation:
It's a linear function. The graph is a straight line, therefore we need only two points.
Select any value of x and calculate the value of y:
y = -3x + 4
for x = 0 → y = -3(0) + 4 = 4 → (0, 4)
for x = 2 → y = -3(2) + 4 = -2 → (2, -2)
Answer:
$441
Step-by-step explanation:
Since each ticket costs 10.50 and you buy 42 :
10.5 * 42 = 441
This set notation really seems the hard way to exclude a single value. Anyway...
The domain doesn't include where the denominator is zero, 4x + 7 = 0,
x = -7/4
The range doesn't include the asymptotic value, which is
y=2x/4x = 1/2
So we need domain x ≠ -7/4 and range y ≠ 1/2
Answer: First choice
Answer:

Step-by-step explanation:
The formula for the volume of a cone is:

Given:
- Radius = 2cm
- Height = 9cm
Let's plug these into the equation:

Now solve:

Therefore, the volume of the cone is 37.7cm^3.
