1. The bear population in Canada was 380,000 in the year 2015, environmentalist think that the population is increasing at a rat

e of 2.5% per year. Consider the function that represents the exponential growth of the bear population in Canada.
Part A: Defines a variable for the function and state what the variable represents.

Part B: What is a reasonable domain for the situation?

Part C: Write the function that represents the exponential growth of the bear population.

Part D: What will the bear population estimated to be in 2050?

POSSIBLE POLYGONS Determine if it is possible for a regular polygon to have an interior angle with the given angle measure. Expl
grigory [225]

Answer:

yes for all 4.

Step-by-step explanation:

I am not sure I see the whole information.

but if the question truly is simply, whether a polygon can have an internal angle of 165 or 171 or 75 or 40 degrees, then the answer is a resounding yes to all 4.

the simplest polygon is a triangle.

the sum of all angles in a triangle is always 180 degrees.

so, any angle smaller than 180 degrees is a possible internal angle in a triangle (and therefore in polygons in general), because the difference to 180 can then be split into 2 angles (e.g. half/half).

so, if one angle is 165 degrees, then the other two angles have to have 15 degrees together (e.g. 10 and 5, or 7 and 8, or 2 and 13, or ...). they will be narrow angles, but they are still angles.

similar for 171 degrees. now the other two angles have to have only 9 degrees together. like 5 and 4.

for 75 degrees the other two angles must have 180-75 = 105 degrees together. like 20 and 85.

for 40 degrees the other two angles must have 180-40 = 140 degrees together. like 90 and 50.

Students rented buses and vans to go to a hockey game. There were 8 vans and 12 buses for 360 students.
scoundrel [369]

Answer:

A: 8v+12b=360

V= van

B= Bus

B: Each van=9

Need to ride in vans:72

Step-by-step explanation:

12 buses 24 in each bus that equals 288. 360-288=72

and if you need to know how many are in each van you divide 72 by the number of vans that would be 9 per van.

HELP PLSS! I need help on all the questions down below
andrey2020 [161]

Points, planes, lines and rays are part of what make up a geometric plane

<h3>Three collinear points</h3>

These are any three points that are on the same line

Points M, P and L are on the same straight line.

Hence, the three collinear points are M, P and L

<h3>Four non-coplanar points</h3>

These are any four points that are not on the same plane

Points N, X, L and S are not on the same plane

Hence, the non-coplanar points are N, X, L and S

<h3>The intersection of lines NQ and ML</h3>

This is the point where both lines meet.

The lines NQ and ML meet at point P

Hence, the intersection of lines NQ and ML is point P

<h3>The intersection of the three planes</h3>

This is the point where the three planes meet.

The three planes meet at point V

Hence, the intersection of the three planes is point V

<h3>Why a line cannot meet a plane at two points</h3>

Because a line has only one dimension

<h3>Why a plane cannot be named by any three points</h3>

Because a plane must have three points and the points must not be on a straight line.

<h3>The length of XZ</h3>

We have:

X = -16

Z = 20

The length is calculated as:

XZ = |Z - X|

This gives

XZ = |20 + 16|

Evaluate

XZ = 36

Hence, the length of XZ is 36 units
