Name a pair of vertical angles, a straight angle, and two acute angles<br> other than
malfutka [58]

Step-by-step explanation:

While there are no examples available, there is the room to understand each angle type you listed, vertical angles are angles that are opposite from each other, and they are congruent (they have the same angle in degrees) now, imagine that for vertical angles, they are in an X top and bottom are equal, and the two sides are equal. For a straight angle, that is usually two angles that are right angles (90 degrees) back to back, meaning when you add 90 and 90 degrees together, you get a straight line or a 180 degree angle. An example of an acute angle is any angle less than 90 degrees, that is a real number, so imagine 25, 40, and 60 as all acute angles.

Hope this helps you identify them in your problem!

12. 5x

13. 5/x-z

Step-by-step explanation:

12. product means multiplication so multiply 5 by x= 5x

13. quotient means division and difference means subtraction. so you divide 5 by x-z= 5/x-z

Write an exponential growth function, and then describe a real-world situation that the function could represent. Do the same fo
Irina18 [472]

Answer:

Step-by-step explanation:

Exponential growth function can be represented as follows

y = e^{bt}

Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or

dy / dt =by , or rate of increase depends upon y itself

dy / y = bdt

integrating on both sides

lny = bt

y = e^{bt}

It represents very fast increase in y .

The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.

For exponential decay function

y = e^{-bt}

The decay of   a radioactive material is an example of exponential decay function.
