After obtaining a warrant, the police attached GPS tracking device to the car of a murder suspect. Suppose the car was located a

AURORKA [14]

Answer:

Part a) The coordinates of the suspect's car at its final destination are (4,4)

Part b) The distance traveled by the suspect was 10 miles

Part c) $d=5.66\ mi$

Step-by-step explanation:

The correct question in the attached figure

Part a) What are the coordinates of the suspect's car at its final destination?

we know that

The original position is the origin of a Cartesian coordinate system (0,0)

1) The suspect's car was tracked going 5 mi due east

That means----> 5 mi at right

the new coordinates are (5,0)

2) The suspect's car was tracked going 4 mi due north

That means----> 4 mi up

the new coordinates are (5,4)

3) The suspect's car was tracked going 1 mi due west

That means----> 1 mi at left

the new coordinates are (4,4)

therefore

The coordinates of the suspect's car at its final destination are (4,4)

Part b) What was the distance traveled by the suspect?

The distance traveled is

5 mi due east + 4 mi due north + 1 mi due west

$5+4+1=10\ mi$

therefore

The distance traveled by the suspect was 10 miles

Part c) What is the distance as the crow flies between the original position and the final position of the suspect's car?

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

Remember that

The original position was (0,0) and the final position was (4,4)

substitute in the formula

$d=\sqrt{(4-0)^{2}+(4-0)^{2}}$

$d=\sqrt{(4)^{2}+(4)^{2}}$

$d=\sqrt{32}\ mi$

$d=5.66\ mi$

The Rodriguez family and the Hill family each used their sprinklers last summer. The water output rate for the Rodriguez family'

brilliants [131]

Answer:

x = 23.33 hr Rodriguez sprinkler

y = 26.66 hr Hill sprinkler

Step-by-step explanation: INCOMPLETE QUESTION

Requiered information:

the water output rate for both sprinkler families

We assume : Rodriguez family 40 lts/hr

Hill family 35 lts/ hr

Total water output 1900 lts

and total combined hours working is 50 hr

Let call "x" time in hours sprinkler of Rodriguez family worked

and "y" time in hours sprinkler of Hill family worked

Then if total output was 1900 lts

40*x + 35*y = 1900 and x + y = 50

We have a two equation system, solving

y = 50 - x ⇒ 40*x + 35 * ( 50 - x )

40x = 1750 - 35x

75 x = 1750 ⇒ x = 1750/75 ⇒ x = 23.33 hr

and y = 50 - 23.33 ⇒ y = 26.66 hr
