Find all the points that are on the x-axis that are a distance of 13 units from the point (12,-5).

Viefleur [7K]

Let point A(x,y) be the point on the x-axis. All points that lie on the x-axis have y-coordinate equal to 0, then A(x,y).

Find the distance from point A to point (12,-5):

$d=\sqrt{(x-12)^2+(0-(-5))^2}=\sqrt{(x-12)^2+25}.$

This distance is equal to 13, then

$\sqrt{(x-12)^2+25}=13,\\ \\(x-12)^2=169-25,\\ \\(x-12)^2=144,\\ \\x-12=12 \text{ or } x-12=-12,\\ \\ x=24 \text{ or }x=0.$

You get two ponts (0,0) and (24,0).

An arrow is shot vertically upward from a platform 19ft high at a rate of 163ft/sec. When will the arrow hit the ground? Use the

Triss [41]

Answer: 10.3 s

Step-by-step explanation:

Given

The height of the arrow is given by $h=-16t^2+v_ot+h_o$

At $t=0, h=19\ ft$ and $v_o=163\ ft/s$

When arrow hits ground, h becomes 0 i.e.

$\Rightarrow 0=-16t^2+163t+19\\\Rightarrow 16t^2-163t-19=0\\\\\Rightarrow t=\dfrac{163\pm \sqrt{(-163)^2+4(16)(19)}}{2(16)}\\\\\Rightarrow t=-0.115,10.30\ s$

Neglecting the negative value of t

So, the arrow hits the ground after 10.30 s
