Answer:
Step-by-step explanation:
The computation of the magnitude is shown below:
Data provided in the question
Given points
R(3,7,-1), S(10,-4,0)
Now the distance lies between R and S
RS = (10 ,-4, 0) - ( 3 ,7, -1 )
= (10 - 3, -4 - 7, 0 - (- 1))
= (7, - 11, 1 )
After that, the magnitude is determined by using the following calculation part
h= 1.5y + 2
h representative height. 1.5y represents 1.5 feet each year. +2 represents the 2 feet it starts with.
135 √ 3 y 243
y = -2.5x + 5
10x + 4y = 20
Subtract 10x from both sides.
4y = -10x + 20
Divide both sides by 4.
The experienced window washer can wash all the windows in Mike’s house in 2 hours, which implies that in 1 hour he completes 1/2 of the job.
By the same logic, the new trainee completes 1/7 of the job in one hour.
If they work together, they complete
of the job in one hour, meaning that they complete the job in 14/9 of a hour.
