Which graph represents the function f(x)=4 / x
REY [17]

Answer: The graph of rectangular hyperbola represents the function f(x)=4/x.

Explanation: given function, f(x)= 4/x.

The above function shows equation of rectangular hyperbola or equilateral hyberbola.(because, it is the type of xy=c^2.)

Thus, the asymptote  of the given function must be perpendicular.

Moreover, if x=2, y=2, if x=-2, y=-2

                 If x=4, y=1, if x=-4, y=-1

Therefore, this hyperbola is passing through points (2,2), (-2,-2), (4,1) and (-4,-1).

Use the circle graph to determine how much hours per day Becky spends on each activity?
blagie [28]

WE know 1 day = 24 hours

To find number of hours spent on each activity, we multiply the corresponding percentage by 24

School :         25 % --> 0.25 * 24 = 6.00 hrs

Eating :          10 % ----> 0.1 * 24 = 2.40 hrs

Sleep :           40 % ----> 0.4 * 24 = 9.60 hrs

Homework:   10 % ---->0.1 * 24 = 2.40 hrs

Free time:      15 % -----> 0.15 * 24 = 3.60 hrs

193.75¨*4%=7.75

193.75+7.75=201.5

Now, you have to calculate 16% of the amount including the tax:

201.5*16%=32.24

According to this, the answer is that if Luca wants to leave a 16% tip on the total amount including the tax, he should pay $32.24.
