If the function is:
y=a cos( bx+c), or y=a sin(x+c)
then the period is T= 2π/b and if T=2:
2=2π/b
b=2π/2=π
Answer: B) y=3 cos πx
Answer:
8/13
Step-by-step explanation:
Let the number be x
if five times a number added to 4 is divided by the number plus 6 the result is nine halves
- five times the number = 5x
- five times a number added to 4 = 5x+4
- five times a number added to 4 is divided by the number = (5x+4)/x
- five times a number added to 4 is divided by the number plus 6 = (5x+4)/x + 6
- nive halves = 9*(1/2)
five times a number added to 4 is divided by the number plus 6 the result is nine halves
(5x+4)/x + 6 = 9(1/2)
=>(5x+4)/x + 6 -6 = 9(1/2) -6 = 9/2-6 = (9-6*2)/2 = -3/2
=>(5x+4)= -3/2 *x= -3x/2
=>2(5x+4) = -3x
=> 10x +8 = -3x
=> 10x+3x = 8
=> 13x = 8
=> x = 8/13
Thus, the number is 8/13
First the answer is 7 but how you get it is
refine 4x+1+5x: 9x+1 and that turns into 9x+1=64
then 9x+1-1=64-1
next you do 9x/63 and that gives you 7
The Captain. Whitman is mourning the death of Lincoln whom he (Whitman) considered the most moral of men. Whitman genuinely appreciated who Lincoln was and what he was forced to do as president. Lincoln is the Captain.
The Ship. The ship is what is left of the United States after the Civil War. It was a bloody confrontation and America is left momentarily poorer after the war was over.
The Prize was the "peaceful" reunification of the United States.
The Port was the end of the ship's journey. It is made up of people glad to see the ship returning
