Answer:

$x=30$

Step-by-step explanation:

Both triangles in this figure are similar. Therefore, we can set up the following proportion:

$\frac{21}{x}=\frac{14}{20}$ .

Cross-multiply to solve:

$14x=21\cdot 20,\\x=\frac{21\cdot20}{14},\\x=\fbox{$30$}$ .

A football is kicked from the ground and follows the graph of the function y = –t2 + 3t, where y represents height and t represe

vesna_86 [32]

Answer:

The height of the objects are the same after 2 seconds.

Step-by-step explanation:

In order to calculate at which time both objects have the same height we need to find the value of t that makes both equations equal. Therefore:

$-t^2 + 3t = -t + 4\\t^2 - 3t - t + 4 = 0\\t^2 - 4t + 4 = 0\\t_{1,2} = \frac{-(-4) \pm \sqrt{(-4)^2 - 4*1*4}}{2*1} = \frac{4 \pm \sqrt{16 - 16}}{2}\\t_{1,2} = \frac{4}{2} = 2$

The height of the objects are the same after 2 seconds.
