The coordinates of the edges of the <em>mini-solar</em> cooker are (x₁, y₁) = (0, - 60) and (x₂, y₂) = (0, 60).

The distance between the two edges is 120 centimeters.

The equation for the <em>parabolic</em> mirror is x + 32 = (2/225) · y².

<h3>How to analyze a parabolical mini-solar cooker </h3>

Herein we must understand the geometry of the design of the <em>mini-solar</em> cooker to determine all needed information. The y-coordinates of the edges of the cooker are determined by Pythagorean theorem:

y = \pm \sqrt{(68\,cm)^{2}-(32\,cm)^{2}}

y = ± 60

The coordinates of the edges of the <em>mini-solar</em> cooker are (x₁, y₁) = (0, - 60) and (x₂, y₂) = (0, 60). The distance between the two edges is 120 centimeters.

Lastly, the equation of the <em>parabolic</em> mirror can be determined based on the equation of the parabola in <em>vertex</em> form:

x - h = C · (y - k)²     (1)

Where:

h, k - Coordinates of the vertex

C - Vertex constant

If we know that (h, k) = (- 32, 0) and (x, y) = (0, 60), then the vertex constant of the equation of the parabola is:

0 + 32 = C · 60²

C = 2/225

Then, the equation for the <em>parabolic</em> mirror is x + 32 = (2/225) · y².

Denzil has a four sided spinner.
kramer

Answer:

The probability of getting 3 successive 1's from spinning the spinner 3 times = 0.027

Step-by-step explanation:

The spinner has 4 sides, 1,2,3 and 4

The probability of landing on a 1 = P(1) = 0.3

The probability of landing on a 2 = P(2) = It isn't given

The probability of landing on a 3 = P(3) = x

The probability of landing on a 4 = P(4) = 0.1

If Denzil spins the spinner 3 times, what is the probability of getting 3 successive 1's?

Noting that each spin is independent from one another, the probability of getting 3 successive 1's from spinning the spinner 3 times is given as

P(1) × P(1) × P(1) = 0.3 × 0.3 × 0.3 = 0.027

Hope this Helps!!!
