Answer:
25, 9
Step-by-step explanation:
(p . q)(8) means do q first to 8 then do p to that, which is the same as writing p(q(8)). Then just plug the numbers in.
q(8)=√8+8=√16=4
p(4)=4^2+9=16+9=25
The second one is the opposite order but same reasoning.
p(8)=8^2+9=64+9=73
q(73)=√73+8=√81=9
r = C/(2π)
C = 2πr
Divide both sides by 2π
C/(2π) = r
The answer is 4th point
√5(10 - 4√2)
= (√5×10)-(√5×4√2)
= 10√5 - 4√10
828
12
(-1,0), (0,3) and (2,2.25)
The qualitative graph is as follows:
A(-1,0) ------> B(0,3) ------> C(2,2.25)
Hence, slope = (2.25 - 0)/(2 - (-1)) = 2.25/3
∴ slope = 0.75
