Answer: 1/4
Explanation: Because there is a 1/2 chance that a female will get the first job, and a half chance that a lady will get a second job. So (1/2)*(1/2)=(1/4)
first term = initial number
second term = initial number + common difference
third term = initial number + 2(common difference)
So...
2x+5-(x+4) = common difference
4x+3-(2x+5) = also common difference
2x+5-(x+4) = x+1
4x+3-(2x+5) = 2x-2
Because x+1=2x-2 we can solve for x.
x=3
So the sequence goes... 7,11,15...
19 is the fourth term
The third choice is very useful. It's valid because two things that are both equal to 'y' are equal to each other, and it can be easily solved to find 'x'.
Answer:
86.5 ns
Step-by-step explanation:
The speed in the original direction (horizontally) is unchanged by the vertical force the field exerts. The travel time is ...
time = distance/speed = (4.5×10^-2 m)/(5.20×10^5 m/s) = 8.65×10^-8 s
_____
An engineer would express this time using the SI prefix nano- for 10^-9. The time is 86.5 ns.
Answer:
f ^-1 (x) = 2x+28
Step-by-step explanation:
f(x) = 1/2x-14
Replace f(x) with y
y = 1/2 x -14
Exchange x and y
x = 1/2 y -14
Solve for y
Add 14 to each side
x+14 = 1/2 y -14+14
x+14 = 1/2 y
Multiply each side by 2
2(x+14)= 1/2 y*2
2x+28 = y
The inverse function is
f ^-1 (x) = 2x+28
