Answer:
1000 m of fence can make a 3-sided enclosure of 125,000 m²
Step-by-step explanation:
Let x represent the length of fence parallel to the river. Then the perpendicular dimension is ...
width = (1000 -x)/2
and the enclosed area is ...
area = length×width = (x)(1000 -x)/2
This describes a downward-opening parabola with zeros at x=0 and x=1000. The vertex (maximum) is halfway between, at x=500.
Then the maximum area is ...
area = (500)(1000 -500)/2 = 125,000 . . . . square meters
ANSWER: The length of the entire dash is 700 meters.
EXPLANATION:
Because 20% of the dash equals 140 meters, we can use a variable to figure out the length of the entire dash.
Let x be the length of the entire dash.
The length of the entire dash is 700 meters.
The equation of the line passing through and is
. Here
is the slope of the line.
Substituting numerical values, the equation of the line is
The equation of the line is
0.24
it was 0.24161073 not simplified but since the 1 after the 4 is not greater than five it stays the same and it beccome 0.24
Answer: $547200
Median salary of masters older is 68,100
Total after 36 years= 68,100*36 = $2,451,600
Median Salary of BSc holder is $52,900
Total median salary after 36 years is 52,900*36 = 1,904,400
The difference is $2,451,600-1,904,400 = 547,200
The person with Masters will earn $547,200 after 36 years
