Answer:
( 5 , 10 )
Step-by-step explanation:
Solution:-
- There are two ships, A and B, currently located by their respective coordinates in the cartesian coordinate system:
<u>Position of ship A: ( - 1 , -2 )</u>
<u>Position of ship B: ( -4 , 1 )</u>
- Both ships try to locate a lifeboat. The spotlights used by each ship are modelled as straight line functions of cartesian coordinate originating from their respective ships.
- Spot lights for each ship were able to locate the same lifeboat. The respective spotlights are modelled by the following functions:
<u>Spotlight Ship A: y = 2x</u>
<u>Spotlight Ship B: y = x + 5 </u>
- To locate the position of the lifeboat with respect to the origin ( 0 , 0 ) we will use the spotlight model functions and equate them. This is because the spotlights must converge or meet at the position of lifeboat provided the lifeboat is found by both ships.
- Therefore,
Spotlight A = Spotlight B
y = 2x = x + 5
2x = x + 5
x = 5 , y = 10
<u>Answer:</u> <em>The two spotlight meet at the coordinates ( 5 , 10 ). This is also the position of the lifeboat located by both the ships</em><em>. </em>
At a particular time, objects and their shadows are proportionate.
Therefore, in figure,
--- (1)
where AB is the height of the lighthouse, BC, its shadow and FD is the height of Zara and DE is her shadow.
From the given information,
BC = 36 feet
FD = 4 feet and DE = 3 feet
(1) becomes
AB = 48
Hence, the height of the lighthouse is 48 feet.
The answer is "She Made $13"
Start a $0 then add/subtract her profit/loss.
0-3+4-3+6-2+5-6+12=13
The gradient is the same as the slope.
The gradient is always before the x variable or is the coefficient of the x variable when an equation is in the slope intercept form.
The gradient in this equation is 1
.Answer: C
Step-by-step explanation:
4.5+p would be the full length of 18 since it is sharing the total length.
