Consider the triangle A(4,0), B(-2,4), C(0,6)<br> What will be the equation of the altitude BM?
katovenus [111]

Answer:

BM: <u>y = (2/3) x + 16/3</u> with segment length of 2.77

Step-by-step explanation:

AC formula: m = (6-0)/(0-4) = -3/2

(y-0)/(x-4) = -3/2       y = (-3/2)x + 6   ... (1)

BM slope: BM⊥ AC   m = 2/3

BM formula: (y-4) / (x- -2) = (y-4) / (x+2) = 2/3

y-4 = 2/3 x + 4/3

<u>y = (2/3) x + 16/3</u>   ... (2)    -2≤x≤0.31

intercept of AC and BM (M) from (1) and (2): (-3/2)x + 6 = (2/3) x + 16/3

(13/6) x = 2/3      x = (2/3) / (13/6) = 4/13 ≈ 0.31

y = (2/3) (4/13) + (16/3) = (8/39) + (208/39) = 216/39 = 72/13 ≈ 5.54

M (4/13 , 72/13) or (0.31 , 5.54)

segment BM = √(4/13 - -2)² + (72/13 - 4)² = √1300/169 = 2.77

4. A boat sails east for 35 miles and then turns to sail 10 miles south. What is the distance of the boat from its ending point
Elden [556K]

Answer:

36.4mi

Step-by-step explanation:

The boat sailed two legs of a right-angled triangle.

The distance from the starting point is the hypotenuse of the triangle.

d = √(35² + 10²)

  = √(1225 + 100)

  = √1325

  = 36.4 mi

What’s the answer??????? Pleaseeeeeeee helppppppppppp
Vinvika [58]

Hello from MrBillDoesMath!

Answer:

Choice A,   18x - 6y = 20


Discussion:

Given line  

-9x + 3y = 12     (M)


Choice A:

18x - 6y = 20  =>          divide both sides by -2

-9x + 3y = -10     (N)


The left hand sides of (M) and (N) are equal implying that right hand sides are equal which further implies 12 = -10.  Contradiction! so the system M and N has no solution.


Thank you,

MrB
