Limestone rocks dissolving in water. All other options are forms of physical weathering.
Answer:
8.5
Step-by-step explanation:
First we need to get BC using the pythagoras theorem
BC² = AC² + AB²
BC² = 8² + 15²
BC² = 64+225
BC² = 289
BC = √289
BC = 17
DB = 1/2BC
DB = 1/2 * 17
DB = 8.5
Hence the length of DB is 8.5
Yes I think. I pretty sure yes
Step-by-step explanation:
Hey there!!
Just simply work with it.
We know that we have to use one point formula to find the equation of a st.line passing through point and slope is given.
So, just do accordingly.
The point is (2,-6) and slope is -1.

Where, "m" is a slope.
Put all values.

Simplify them to get answer.


Therefore the equation is y= -x-4 OR can be written as x+y+4=0.

Its choice d because 1^2 - 5(1) + 6
= 1 - 5 + 6
= 2
