The value of y is 6 when x is 4
Step-by-step explanation:
If x varies inversely as y, then
- x =
, where k is the constant of variation - xy = k, you can find k by using the initial values of x and y
∵ x varies inversely as y
∴ x =
∵ When x = 3, y = 8
- Substitute these values in the equation to find k
∴ 3 = 
- Multiply both sides by 8
∴ 24 = k
∴ The equation of variation is x = 
∵ x = 4
- Substitute the value of x in the equation to find y
∴ 4 =
- Multiply both sides by y
∴ 4y = 24
- Divide both sides by 4
∴ y = 6
The value of y is 6 when x is 4

Put a negative sign in front of the 3/2
Answer:
15 yds
Step-by-step explanation:
40 divided by 50 equals 4/5, so the lengths of the other triangle have to match that ratio. 3 fits into 12 four times and 15 five times, which makes it a four to five ratio.
Given :
To Find :
the absolute minimum and absolute maximum values of f on the given interval
[-1,2] .
Solution :
Now , getting first order differential equation and equating its equal to zero.
So , x=0 is critical point .
Now , coefficient of 
is positive .
Therefore , it is increasing function after x=0 .
So , min value will be at , x=0.
And maximum value will be the maximum at the x=2 because it is increasing function .
Therefore , max and min value is 9 and -3 respectively .
Hence , this is the required solution .
