Superposition and geologic timescale support the theory because of the changes in features in index fossils of diverse periods are presumed to be caused by evolution, and the existence of different organisms in different periods is then used to support biological evolution.
Answer:
-1/5
Explanation:
It is an established mathematical proof that the slope of line A perpendicular to another line B is the recoprovaknofokad
Hence the slope of B = the negative reciprocal of B
Given that ; lines s and t are perpendicular ;
Slope of S = 5 ;
The slope of T = - 1/5
<span>During the stage of internal combustion engine operation in which the piston rises and compresses the fuel in the combustion chamber, the intake and exhaust valves will both be closed. This means that the mixture of fuel and air are compressed, due to the seal around the combustion chamber that has been created by the closure of both of these valves. Hopefully that answered your question for you!</span>
