Answer:
Step-by-step explanation:
The domain is the people and the range is the money spent
People would be counted as positive integers, only the last answer choice considers this.
<u>So the answer is:</u>
Perimeter = 2 times the Length + 2 times the Width
You can calculate it using the law of cosines: c^2=a^2+b^2-2*a*b*cos(C)
your triangle is
CD=15=a
CE=?=b
DE=CE+3=b+3=c
and C=90°
-> insert those values, with c substituted with b+3 to remove c
c^2=a^2+b^2-2*a*b*cos(C)
(b+3)^2=15^2+b^2-2*15*b*cos(90)
cos(90)=0->
(b+3)^2=15^2+b^2
b^2+2*3*b+3^2=225+b^2
6b+9=225
6b=216
b=36=CE
DE=CE+3=36+3=39
Answer
Find out the how many traffic lights are there on elm street .
To prove
As given
Elm street is 3.6 kilometers Long .
There are sets of 4 traffic lights every 0.6 kilómeter.
i.e
Now
Traffic light in 3.6 kilometers = Traffic light in one kilometer × 3.6
Traffic light in 3.6 kilometers = 24
Therefore Traffic light in 3.6 kilometers are 24 .
