Area of a right-angled triangle
Work out the area of this right-angled triangle.

30

Explanation:

the formula for calculating the area of a right-angled triangle is ½ × base × height, where the base of the triangle is one of its sides, and the height of the triangle is a line connecting the opposite vertex (corner) of the triangle to the base at a right angle.

in this case, because the triangle is already a right-angled one, we do not have to draw a hypothetical line to serve as the height.

all we have to do is apply the formula using the numbers given in the diagram to represent the base and the height.

½ × base × height = ½ × 12 × 5 = 30

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
