210 I think because theres 3.4 of 60minutes/ hrs and 3.4 times 60 is 209.6 and it said round to the nearest minute which is 9 so 210
Answer:
X=0 or no solution
Step-by-step explanation:
-2x+4=-3x+4
cancel equal terms on both sides of the equation
-2x=-3x
move the variable to the left-hand side and change its sign
-2x+3x=0
collect like terms
x=0
Answer:
A
Step-by-step explanation:
Answer:
Period of the function is 4π
Step-by-step explanation:
Given is a graph:
It oscillates between -1 and +1
The graph shows angles on x axis and trig values on y axis.
The graph has value +1 when x=0 and reaches minimum -1 when x =2pi and again reaches y=1 when x =4 π
Thus we find that this is a periodic function with amplitude 1 and phase shift 0 and period 4π
So we get the period of the trignometric funciton is 4π
So option 1 is right
Verify:
Given function is y = cos
Since parent function y =cosx has a period of 2pi, we have
here period = 2pi/coefficient of x in cos
=2pi/(1/2)
=4pi
Answer:
77:56:48
77:48
Step-by-step explanation:
If x:y=11:8 and z:y=6:7
then;
x/y = 11/8 and z/y = 6/7
11y = 8x and 6y = 7z
x = 11y/8 anad z = 6y/7
Hence;
x:y:z
= 11y/8:y:6y/7
= 11/8:1:6/7
= 11/8 * 7/6
= 77:56:48
x:z = 11y/8:6y/7
x:z = 11/8:6/7
x:z = 77:48
