Answer:
a.Angle. 3
Step-by-step explanation:
Angle 3 is complementary to angle 4.
Because 70+20=90°
Answer:
See attached graph for the first part
Answer to second part: The end part of the graph show the slowest increase
Step-by-step explanation:
The attached picture represents the number of infected people, starting with a relatively small number at the origin of the horizontal axis (x=0, or time=0) then increasing abruptly in the center of the graph with steep slope. and then infection slowing down (although still slowly increasing) in the region highlighted in yellow to the right of the graph.
In the given graph, lets mark two points:
Let
and 
The slope of the line is given by:



The equation of the line is given by:






Therefore, the function equation represented by the graph is: 
Answer:
w≤ -5
Step-by-step explanation:
hello :
w+4≤ -1
w+4-4≤ -1-7
w≤ -5
It's a hexagon.
The formula of the sum of internal angles in the polygon:

Therefore
