grandymaker [24]2 years ago
7 0

Answer:

The answer is C.

Step-by-step explanation:

50-x^2=0

x^2=50

x=\pm \sqrt{50} =\pm \sqrt{25*2}=\pm 5\sqrt{2}

The answer is C (I am assuming that it isn't 5/2).

The product of two consecutive positive integers is 56. Find the two integers
vredina [299]

Answer:

Two consecutive integers are of the form

x and x + 1

Their product is equal to 56

x(x + 1) = 56

Solve and find the two numbers x and x + 1. The above equation may be written as follows

x2 + x - 56 = 0

Factor and solve

(x - 7)(x + 8) = 0

solutions: x = 7 , x = -8

x= - 8 is not valid since the number sought must be positive. Hence

x = 7 and x + 1 = 8 are the two consecutive numbers.

Answer:

  about 81 years

Step-by-step explanation:

A graphing calculator can give you the answer easily.

__

You can solve the problem algebraically by putting in the given number and solving for t.

  30000 = 32000/(1 +12.8e^(-.065t))

  12.8e^(-.065t) = (32000/30000) -1 = 1/15

  e^(-.065t) = 1/(15·12.8) = 1/192 . . . . . divide by 12.8

  -0.065t = ln(1/192) ≈ -5.257 . . . . . .  take the natural log

  t = -5.257/-0.065 ≈ 80.88 . . . . . . . .divide by the coefficient of t

It will take about 81 years for the number of trees to reach 30,000.
