Answer: The distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
Step-by-step explanation:
Since we have given that
Distance between Ships A and B = 1425 feet
Angle of depression from ship A to the submarine =59°
Angle of depression from ship B to the submarine = 47°
As shown in the figure below:
Remaining angle will be
So, we will use "Sine formula ":
Similarly,
Hence, the distance from ship B to the submarine is 1270.68 feet and the distance from ship A to the submarine is 1084.18 feet.
Answer:
4x-1
Step-by-step explanation: because you have like terms you do 6-2=4x-1
Answer:
the scenic route take 6h 40m
Step-by-step explanation:
first we have to make an equation that represents the relationship of each route
x = scenic route
y = direct route
x = y + y * 25/100
now we have to make an equation that represents the routes over time
x + y = 12
we replace the x by what is the same in the first equation (y + y * 25/100) in the second equation
x + y = 12
(y + y * 25/100) + y = 12
2 y + 0.25 y = 12
2.25y = 12
y = 12/2.25
if we spend this in minutes multiplying it by 60
y = 12/2.25 * 60 = 320 m = 5h 20m
x + y = 12
x + (5h 20m) = 12h
x = 12h - 5h 20m
x = 6h 40m
a) The linear function is:
b) The estimate for the number of people employed in 2012 is of 569.2.
-----------------------------
A linear function has the following format:
In which
- m is the slope, that is, how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
-----------------------------
Item a:
- During the first year of observation, the number of people, in thousands of dollars, was of 373. Thus, the y-intercept is
- In 10 years, it changed from 373 to 591, thus, the slope is:
The function is:
-----------------------------
Item b:
2012 is 9 years after 2003, thus, this is
The estimate for the number of people employed in 2012 is of 569.2.
