Factor 9y2 - 12y + 4.<br><br> (3 y - 2)(3 y + 2)<br> (3 y - 4)( y + 1)<br> (3 y - 2) 2
lozanna [386]

Answer:

(y - 2)²

Step-by-step explanation:

9y² - 12y + 4 ← is a perfect square of the form

(ax - b)² = a²x² - 2abx + b²

Compare like terms with 9y² - 12y + 4, thus

a² = 9 ⇒ a = 3

b² = 4 ⇒ b = 2 and

- 2ab = - 2 × 3 × 2 = - 12

Thus

9y² - 12y + 4 = (3y - 2)²

A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,
DIA [1.3K]
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000

Growth rate = r = 150% = 1.50 

The equation model for this situation is:

A= A_{o}(1+r)^{t}

Using the values in above equation, we can write:

45000000=100(1+1.5)^{t}  \\  \\ &#10;450000=(2.5)^{t} \\  \\ &#10;log(450000)=log((2.5)^{t})  \\  \\ &#10;log(450000)=t*log(2.5) \\  \\ &#10;t= \frac{log(450000)}{log(2.5)} \\  \\ &#10;t=14.21

This means, the person will fall sick after about 14 hours.
