Answer:

$y = 2x + 1 \\ 3x + y = \: - 9 \\ \\ 3x + 2x + 1 = - 9 \\ 5x = - 10 \\ x = - 2 \\ \\ y = 2( - 2) + 1 \\ y = - 3 \\ ( - 2 \: and \: - 3)$

Step-by-step explanation:

Radius = 4/2 = 2 in

SA = 2pi×r×h + 2pi×r²

= (2×3.14×2×6) + (2×3.14×2²)

= 100.48 in²

An easy way to do this is to parameterize the directed line segment from B to A by the function

$\ell_{B\to A}(t) = (1-t) B + t A = (1 - t) (11, 17) + t (-9, 4)$

with 0 ≤ t ≤ 1.

The point P₂ splits up AB so that BP₂ = 3/8 AB and AP₂ = 5/8 AB. Then we reach the point P₂ when t = 3/8, so its coordinates are

$P_2 = \ell_{B\to A}}\left(\dfrac38\right) = \dfrac58 (11,17) + \dfrac38 (-9,4) = \boxed{\left(\dfrac72, \dfrac{97}8\right)}$

Divide both by 5/8 because 5/8 divide by 5/8 =1
(1/2)/(5/8)
1/2*8/5
8/10
4/5
