Answer:
C = 80pF
Step-by-step explanation:
The total capacitance of 4 capacitors connected in series is given by:
Solving for C:
C = 4*20pF
C = 80pF
Answer:
EH = 13 in
Step-by-step explanation:
Angle between a tangent and radius is right, that is
∠ EBH = 90° and so Δ EBH is right
Using Pythagoras' identity in the right triangle
EH² = BE² + BH² = 5² + 12² = 25 + 144 = 169 ( square root both sides )
EH = = 13
Answer:
Your answer would be d.
Step-by-step explanation:
The numbers are 6 and -2.
6 + -2 is 4
as well as 6 x -2 is -12
Assuming that the order of selection is not important, this is a question of number of ways. In other words, the combination should be computed. That is,
Number of ways of selection 5 flowers = 12C5 = 12!/{5!*(12-5)!} = 12!/{5!*7!} = 792
Therefore, there are 792 ways in which 5 flowers can be selected from the available 12 flowers.
