4 0

Answer:

f(x)=-3(x-8)(x+2)

Step-by-step explanation:

f(8)=-3(8-8)(8+2)=-3×0×10=0

f(-2)=-3(-2-8)(-2+2)=-3×(-10)×0=0

f(0)=-3×(0+8)×(0+2)=-3×8×2=-48

Tomtit [17]
  1. Yes; alternate interior angles.
  2. A counterexample to dispute the validity of the converse statement is that if two angles are congruent, then they are supplementary angles.

<h3>What is a conditional statement?</h3>

A conditional statement can be defined as a type of statement that can be written to have both a hypothesis and conclusion. This ultimately implies that, it typically has the form "if P then Q."

<u>Where:</u>

P and Q represent sentences.

<h3>What is a converse statement?</h3>

A converse statement can be defined as a type of statement that is obtained by switching (reversing) the hypothesis and conclusion of a conditional statement. This ultimately implies that, the converse of a statement is obtained by switching (reversing) the hypothesis and  conclusion of a conditional statement.

In this context, we can reasonably infer and logically deduce that Jenni wrote the converse statement properly i.e yes; alternate interior angles.

A counterexample to dispute the validity of the converse statement is that if two angles are congruent, then they are supplementary angles.

In a lab experiment, 80 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to doub
Effectus [21]

Answer:

The hourly growth rate is of 4.43%.

The function showing the number of bacteria after t hours is P(t) = 80(1.0443)^t

Step-by-step explanation:

Equation of population growth:

The equation for the population after t hours is given by:

P(t) = P(0)(1+r)^t

In which P(0) is the initial population and r is the growth rate, as a decimal.

The conditions are such that the number of bacteria is able to double every 16 hours.

This means that P(16) = 2P(0). We use this to find r.

P(t) = P(0)(1+r)^t

2P(0) = P(0)(1+r)^{16}

(1+r)^{16} = 2

\sqrt[16]{(1+r)^{16}} = \sqrt[16]{2}

1 + r = 2^{\frac{1}{16}}

1 + r = 1.0443

r = 1.0443 - 1

r = 0.0443

The hourly growth rate is of 4.43%.

80 bacteria are placed in a petri dish.

This means that P(0) = 80.

P(t) = P(0)(1+r)^t

P(t) = 80(1+0.0443)^t

P(t) = 80(1.0443)^t

The function showing the number of bacteria after t hours is P(t) = 80(1.0443)^t
