Coordinates of midpoint

Answer:
1. The growth rate is 2
2. The sample is losing half its mass, so the decay factor is 1/2 or 0.5
Step-by-step explanation:
The growth and decay factor in an exponential function is the number that is being multiplied to the power of x
- It is a growth rate when that number is greater than 1
- It is a decay rate when the number is less than 1
- If it's 1 then it's not growing or decaying
- If it's 0 you will have an answer of 0
There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.
You were right, its the second choice CA=CB+BA
Answer:
30.11 meters ( approx )
Step-by-step explanation:
Let x be the distance of a point P ( lies on the building ) from the top of the building such that AP is perpendicular to the building and y be the distance of the building from point A, ( shown in the below diagram )
Given,
Point A is 8.20 m above level ground,
So, the height of the building = ( x + 8.20 ) meters,
Now, 1 degree = 60 minutes,
⇒ 


By the below diagram,




Now, again by the below diagram,



Hence, the height of the building = x + 8.20 = 30.11 meters (approx)
