Use Desmos insert y=0.4x into the calculator
Answer:
D. 10
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr²h
V = π(4 in)²(13 in) = 208π in³
The volume of a cone 3 inches in radius and 7 inches high is ...
V = (1/3)πr²h = (1/3)(3 in)²(7 in) = 21π in³
Then the ratio of the volume of the cylinder to that of the cone is ...
(208π in³)/(21π in³) ≈ 9.905
You would need to fill the funnel about 10 times to fill the can.

What do you mean about his
Answer:
x = - 2.5
Step-by-step explanation:
Given that the sketch represents
y = x² + bx + c
The graph crosses the y- axis at (0 , - 14), thus c = - 14
y = x² + bx - 14
Given the graph crosses the x- axis at (2, 0), then
0 = 2² + 2b - 14
0 = 4 + 2b - 14 = 2b - 10 ( add 10 to both sides )
10 = 2b ( divide both sides by 2 )
b = 5
y = x² + 5x - 14 ← represents the graph
let y = 0 , then
x² + 5x - 14 = 0 ← in standard form
(x + 7)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x - 2 = 0 ⇒ x = 2
The x- intercepts are x = - 7 and x = 2
The vertex lies on the axis of symmetry which is midway between the x- intercepts, thus
the x- coordinate of the turning point is
=
= - 2.5
