The table below shows the total number of hours Jessica, Emily, and Trina each studied after a given number of weeks. One of the relationships between weeks and total hours studied is proportional.

Whose number of total hours studied is proportional to the number of weeks studied?
For the proportional relationship, write an equation to represent y , the total number of hours studied, in terms of x , the number of weeks.
Explain how you determined your equation.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

about 0.75 hours

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
