the end points of MP are M(2,1) and P(14,10) if point K partitions MP in a ratio of MK: KP= 3:2 what are the cordinates of k HEL
Ronch [10]

Answer:

  K = (9.2, 6.4)

Step-by-step explanation:

If MK : KP = 3 : 2, then ...

  K = (3P +2M)/(3+2)

  = (3(14, 10) +2(2, 1))/5 = (46, 32)/5

  K = (9.2, 6.4)

I need help ASAP , so what’s the answer
aivan3 [116]

The answer would be A.) 1

To find this answer you solve for x. Subtract 3/2 from both sides. This will give you 1/2x = 1/2^x. Then, divide by 1/2 on both sides to get x = 1.

To check this fill in x with 1. Then solve.

  • 1/2 * 1/1 + 3/2 = 2^1
  • 1/2 + 3/2 = 2
  • 4/2 = 2
  • 2 = 2

Thus making 1 the answer. Here's an image to show how I got this. I hope this helps!

If the cost. C, for manufacturing x units of a certain product is given by C= x² + 10x +30, find the number of units manufacture
ipn [44]

Answer:

  100 units

Step-by-step explanation:

We want to find x when ...

  C = 11030

  x² +10x +30 = 11030 . . . . fill in for C

  x² +10x = 11000 . . . . . . . . subtract 30

  x² +10x +25 = 11025 . . . . add 25 to complete the square

  (x +5)² = 105² . . . . . write as squares

  x +5 = ±105 . . . . . . . take the square root

  x = -5 ±105 = {-110, 100}

The number of units manufactured at a cost of $11,030 is 100.
