Answer:

x

Step-by-step explanation:

First we will multiply everything by 10 to get rid of the decimals.

4.2x*10+5.6*10

Subtract 56 from both sides:

42x+56-56

Add 83x to both sides:

42x+83x

Divide both sides by 125:

\frac{125x}{125}

Which of the following statements are true?
Fantom [35]

Answer:

option A and B are correct.

Step-by-step explanation:

Given: p(t) = \frac{64}{1 + 11e^{-.08t} }

Option A: \lim_{t \to \infty} \frac{64}{1 + 11e^{-.08(\infty)} }  = \frac{64}{1 + 0}  = 64

Option A is true,

Option B: P(0) = \frac{64}{1 + 11}  = 5.33

Option B is also true.

Option C:

P(t + 1) = \frac{64}{1 + 11e^{-.08(t + 1)} }  = \frac{64}{1 + 10.15e^{-.08t} } \\1.08 · P(t) = \frac{64 · 1.08 }{1 + 11e^{-.08t} }   = \frac{69.12}{1 + 11e^{-.08t} }

P(t + 1) ≠ 1.08 · P(t)

Option C is incorrect.

Option D:  It is also incorrect, because according to option 2 earth's population will not grow exponentially without Bound.

The second term of the binomial factor should be 3c instead of 3.

Step-by-step explanation:

Distributive property:

a*b + a*c = a*(b +c)

3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)
