Hello there!

Here's what definitions I think match up with each term:

Equilateral triangle: a triangle with three congruent sides
Composite figure: a figure made up of two or more three dimensional figures
Parallelogram: a quadrilateral with opposite sides both parallel and congruent
Volume: the amount of space within a three dimensional figure
Rectangular prism: a three dimensional figure with six rectangular faces, twelve edges, and eight vertices
Regular polygon: a polygon with 5 sides
Triangular prism: a prism with two congruent triangular based
Obtuse triangle: a triangle with one obtuse angle
Face: a flat surface of a three dimensional figure
Polygon: a polygon with congruent sides/congruent angles
Square: a closed figure made up of line segments that do not cross each other

Hope this helped you out! :-)

0.03 x 0.6

= (3 x 6) / 1000

= 18 / 1000

Suppose a scientist reported the following data regarding the presence bacteria during the first four hours of testing for a new

The recursive geometric sequence that models this situation is:

$f(n) = 0.9f(n-1)$

$f(1) = 90000$

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

It can be represented by a recursive sequence as follows:

$f(n) = qf(n-1)$

With f(1) as the first term.

In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:

$q = \frac{65610}{72900} = \cdots = \frac{81000}{90000} = 0.9$

$f(1) = 90000$

Hence:

$f(n) = 0.9f(n-1)$

$f(1) = 90000$

Does anybody know this plz help.

So for this it's asking to multiply 10,000 glass beads by the length of 0.4 cm.

So to make it easier let's just make it a fraction.

This will make it 4/10 (because 0.4 is just 4 tenths of a whole number)

So now we can upscale the sizes to the proper ratio. This ratio being the thousands.

4000/10000

Meaning the answer is 4000cm in length.
