It will be 11v
If you rearrange it to 12v- v
Then it’ll look like 12v- 1v
Which equals 11v
Answer:
a = 150
Step-by-step explanation:
The sum of the internal angles of an octagon is 1080°.
(There are four 
and 4 
, they sum to 1080°)
Hope this helps :)
This looks complicated
lets simplify both sides
By multiplying top and bottom by the conjugate:-
left side = (5-3i)(x + iy) (4+5i) (5-3i)(x + iy) (4+5i)
------------------------ = ------------------------
(4-5i)(4+5i) 41
right side = (2 + i + 3-4)(2+i - 3 + 4i) (by Difference of 2 squares)
= 5-3i)(-1 + 4i)
so as left side = right side
(5-3i)(x+yi)(4+5i) = 41 (5-3i)(-1+5i)
5-3i is common so:-
(x + iy)(4+5i) = 41(-1+5i)
4x +5xi + 4yi - 5y = -41 + 205i
4x - 5y + (5x + 4y)i = -41 + 205i
EQuating coefficients we are left with the system of equations
4x - 5y = -41
5x + 4y = 205
solving this gives x = 21 and y = 25
Answer:
Period = 
The Ferris wheel will complete one round in 40 seconds.
Step-by-step explanation:
We have the function representing the height of the passenger by,
, where t = time in minutes.
It is known that when a function f(x) has period P, then the function a×f(bx+c)+d will have the period 
.
Since, the function 
has period 
, so the function h will have period 
i.e. .
Thus, the period of the given function is .
Now, as the period is minutes i.e 40 seconds.
Hence, we get that the Ferris wheel will complete one round in 40 seconds.
