Consider a dart board made of three concentric circles of radii 1 cm, 2cm and 3 cm, respectively. The points you obtain by hitti
Vlada [557]

Answer:

The answer is 350 points

Step-by-step explanation:

The Area of a circle is πr∧2

The problem states that in the attempts, you never hit the outermost ring in the 10 attempts so we need the area of the 1cm and 2cm circles

Area of the 1st circle;  π X 1∧2 = π

Area of the Second circle; π X 2∧2 = 4π

We also need the area which is the difference between the area of the 1cm and 2cm circle

4π - π  = π

Points 50 = π/4π = 1/4

points 30 = 3π/4π = 3/4

For one attempt,

E(x) = 50 x 1/4 + 30 x 3/4

= 12.25 + 22.5

= 34.75

This is approximately 35

Therefor, 10 individual attempts will be 10 x 35 = 350

(-2,2)(2,-2)
slope = (-2 - 2) / (2 - (-2) = -4/4 = -1

as far as point slope form, there can be 2 answers...

y - y1 = m(x - x1)
slope(m) = -1
using points (-2,2)...x1 = -2 and y1 = 2
now we sub
y - 2 = -1(x - (-2) =
y - 2 = -1(x + 2) <== or could be written as y - 2 = - (x + 2)

y - y1 = m(x - x1)
slope(m) = -1
using points (2,-2)...x1 = 2 and y1 = -2
now we sub
y - (-2) = -1(x - 2) =
y + 2 = -1(x - 2) <== or can be written as y + 2 = - (x - 2)

either one of those answers is ur point slope form
