<h2>9 ft</h2>

Step-by-step explanation:

       The height of kangaroo after it jumps is represented by the function h(t)=24t-16t^{2}, where t is in seconds, height is in feet.

       To find the maximum height that the kangaroo jumps, we need to maximise h(t).

       The minimum/maximum value of a quadratic expression ax^{2}+bx+c is given by \dfrac{4ac-b^{2}}{4a}.

       As the coeffecient of quadratic term is negative, the function has a maxima.

       Maximum value = \dfrac{4(-16)(0)-(24)^{2}}{4(-16)}=\dfrac{-576}{-64}=9.

∴ Maximum height = 9 ft

What single transformation maps ∆ABC onto ∆A'B'C'? A. rotation 90° clockwise about the origin B. rotation 90° counterclockwise a
Klio2033 [76]

Answer:

B. rotation 90° counterclockwise about the origin.

Step-by-step explanation:

Transformation is the process by which the size or orientation of a given figure is altered without any effect on its shape. Examples are; rotation, reflection, translation and dilation.

Rotation is the process of turning a figure about a reference point called the origin. While reflection is turning a figure about a line to produce its image.

In the given question, ∆ABC is  mapped onto ∆A'B'C' by rotating it at 90° counterclockwise about the origin.
