Answer:
5/2
Step-by-step explanation:
Negative slopes go left to right downwards if I remember correctly
Answer:
Apply cosine rule:
c²=b²+a²-2ba cosC
C= pi/3 = 180/3 = 60 degrees
cosine 60 deg = 0.5
c²=2²+3²-[2×2×3×0.5]
c²=7
c=√7
c=2.645 ;length of third side of angle
Step-by-step explanation:
average of 4 numbers is 11 so 11*4 = 44
average of 5 numbers is 12.4 so 12.4*5 = 62
the 5th number = 62-44 = 18
Answer:
c. both
Step-by-step explanation:
Given equation is 
Now we need to check if the graph of
is symmetric with respect to which axis?
a. x-axis c. both b. y-axis d. neither
We know that if f(-x) reflect the graph about y-axis
so let's change x by -x into given function to see if that equation remains unchanged or not


That is same as previous equation.
<u>Hence given graph is symmetric about y-axis.</u>
We know that if -f(x) reflect the graph about x-axis
so let's change y by -y into given function to see if that equation remains unchanged or not


That is same as previous equation.
<u>Hence given graph is symmetric about x-axis.</u>
So the correct choice is c. both
