The area of this figure is 30 square cm.
Explanation
The figure consists of a rectangle and right angled triangle.
length of the rectangle l=6cm
breadth of the rectangle b=4 cm
area of the rectangle=lb=6*4 =
hypotenuse of the right angled triangle=5 cm
height h=4 cm
we have to calculate the base using pythagoras theorem
area of the triangle=
are of the figure=area of the rectangle+area of the triangle=24+6=30 sq cm
The range of the parabola that opens down and has its vertex as (2, 5) is (b)
The vertex of a parabola can represent the minimum or the maximum point in the parabola
The vertex of the parabola is given as:
The range of a function is the set of output values the function can take
From the question, we understand that the parabola opens down.
This means that, the vertex of the parabola is a maximum.
Hence, the range of the parabola is
