bekas [8.4K]

Answer:

$y=2\sqrt{3}\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

<em>In the right triangle ABC</em>

$AC=BC$ -----> by a 45°-90°-45° triangle

so

$cos(45\°)=\frac{BC}{AB}$

$BC=ABcos(45\°)$

substitute the values

$BC=(2\sqrt{2})(\frac{\sqrt{2}}{2})=2\ units$

<em>In the right triangle BCD</em>

$tan(60\°)=\frac{BD}{BC}$

substitute the values

$\sqrt{3} =\frac{y}{2}\\ \\ y=2\sqrt{3}\ units$

Heather left the hospital and drove toward the desert at an average speed of 35 km/h. Danielle left sometime later driving in th

elena55 [62]

Answer:

Danielle drove 3 hours

Step-by-step explanation:

Suppose Heather moved in the x direction.

Then Danielle moved in the opposite direction, that is, she moved in the -x direction.

Let's call $V_1$ , $x_1$ , $t_1$ at the speed, distance and time that I code Heather

Let's call $V_2$ , $x_2$ , $t_2$ at the speed, distance and time Danielle codes.

Observe the following diagram:

(x) Heather <------ $x_1$ --------- hospital ---------- $x_2$ -----------> Danielle (-x)

So:

$V_1 = 35\ km/h$

$t_1 = 4\ h$

$V_2 = 50\ km/h$

We know that after 4 hours the distance between Heather and Danielle was 290 km.

That is to say:

$x_2 + x_1 = 290\ km/h$

We know that $x_1= v_1t_1$

$x_1 = 35(4)$

$x_1 = 140\ km$

We already know $x_1$ , the distance from the hospital to Heather, so we can find $x_2$ and thus know $t_2$

So:

$x_2 = 290 - 140\\\\x_2 = 150\ km$

Then:

$t_2 = \frac{x_2}{v_2}\\\\t_2 = \frac{150}{50}\\\\t_2 = 3\ h$
