Yes, HJ = 30 ft.
It tells us that triangle DEF = triangle GHJ.
By seeing this we know without looking at the triangles that EF is going to be the same as HJ because when they say a figure is the same as another and list the letters such as 'DEF' and 'GHJ' they will list them in the same order.
So
'DEF' = 'GHJ' we get:
'DE' = 'GH'
'EF' = 'HJ'
And we can do the last and first letters:
'FD' = 'JG'
And since we know 'EF' = 'HJ' and that they already told us 'EF' was 30, we know HJ will be 30.
C because they added up to that number
Answer:
quadrant I
Step-by-step explanation:
The variable I=f(w) represents the number of individuals (in thousands) infected w weeks after the epidemic begins.
The value of I=f(2) represents the number of individuals in thousandas infected 2 weeks after the beginning of the epidemic.
From the graph, where I=8, we can conclude that there are 8,000 infected people after 2 weeks of the beginning of the epidemic.
Answer:
f(2) = 8
Means 8,000 people are infected after 2 weeks of the beginning of the epidemic.
