Simple geometrical shapes appear on some national flags too. For example, the flag of the Republic of Trinidad and Tobago is made up of two triangles and three parallelograms. The width of each white portion is 1/30 of the length of the flag and the width of the black portion is 2/15 of the length of the flag. Calculate the following ratio : area of red portion : area of black portion : area of white portion.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
