Determine what type of model bet fits the given situation: Every day, half a bacteria population dies. A. Linear B.quadratic C.
makvit [3.9K]

Answer:

Exponential

Step-by-step explanation:

<em>Starter:</em>

According to the title:

"Every day, half a bacteria population dies."

Exponential: y = ab^x ( b > 0 , b ≠ 1)

So the answer is C.

<em>Calculations:</em>

An exponential model is of the form y = a • b^t.

If you start with population of 500 million bacteria

t = 0

so 500 million = a • b^0 = a

Since every day half the population dies then in 1 day population will be 250 million

so a = 500 million, y = 250 million and t = 1

250 million = 500 million • b^1

b = 0.5

Therefore your equation would be

y = 500 million (or whatever the pop) • 0.5^t

Where t = number of days

This could also be written in exponential form ( e = 2.73)

nekit [7.7K]
V=x³-7x+6, V=(x-2)(x+3)*h

(x-2)(x+3)*h=x³-7x+6

h{x²+x-6}=x³-7x+6

h=(x³-7x+6)/(x²+x-6)

Therefore h=x-1

-----------------------------

Check answer:

V=(x-2)(x+3)(x-1)

=(x-1)(x²+x-6)

=x(x²+x-6)-1(x²+x-6)

=x³+x²-6x-x²-x+6

=x³-6x-x+6

=x³-7x+6
