Answer:
1)7*3
4)m^2
Step-by-step explanation:
The first four problems deal with the area of the rectangle, or length times width(7*3,m*m=m^2).
The last four problems are dealing with adding areas. Find the area of the two rectangles(length times width), then add them together to find the total area.
Answer:
The constant of proportionality is for every 1 x, there is 0.25 y. y = 0.25, and on a graph, x is always the "1." Since x is worth 1, y must be worth 0.25.
Step-by-step explanation:
3sinx+1=sinx
2sinx+1=0
2sinx=-1
sinx=-1/2
x=sin^-1 (1/2) = 30 =
/6 (when finding the inverse, always take the positive value, ignore the negative sign)
x is therefore negative in 3rd and 4th quadrant
Therefore values of x are:
180+30=210 = 7
/6
360-3=330 = 11
/6
