Answer:
Decay
Step-by-step explanation:
We are given an equation 
We need to say about decay or growth of exponential function.
Exponential function: 
Where,
- a is initial value of exponential function.
- b is decay or growth of function
For decay: 0<b<1
For growth: b>1
Now we rewrite the equation into this form

Changes to

Here, b=0.5 < 1
Therefore, The given function would be decay.
Thus,
is deacy.
Answer:
- B - tan A = 4/3, sin B = 3/5
Step-by-step explanation:
<u>First, lets find the length of the third side</u>
- b = √15² - 12² = √225 - 144 = √81 = 9
<u>Now, lets get Tan A and Sin B</u>
- Tan A = 12/9 = 4/3
- Sin B = 9/15= 3/5
Correct option is B
Vertex<span> typically means a corner or a point where lines meet for an example i guess you can say squares have four corners, each is called </span>a vertex<span>. The plural form of </span>vertex<span> is </span>vertices<span>.</span>
Answer:
Maybe 12…
Step-by-step explanation:
would it be 12? I really don’t know sorry.
If I get it wrong I can just have a question and post it and you can get some points.
Answer:
11.176 meters/second
Step-by-step explanation:
1 mile = 1609.34 meters
25 miles = 40233.6 meters
1 hour = 60 minutes
1 minute = 60 seconds
1 hour = 3600 seconds
40233.6 / 3600,
11.176 meters/second
