Answer:
Hundreds is 8, tenths is 5, and thousandths is 1!
Answer:
x-intercept of the graph of the function is,
Step-by-step explanation:
Given the function: ......[1]
x-intercept defined as the graph crosses the x-axis.
Substitute value of y = 0 in [1] and solve for x;
or
Take the inverse cotangent of both sides of the equation and solve for x;
3x = arccot (0)
We know the exact value of
then;
Divide both sides by 3 we get;
Since, the cotangent function is positive in the first and third quadrants.
The period of the function is so values will repeat every radians in both directions.
we have;
Therefore, the x-intercept of the graph of the function is ;
for every integer n;
Answer:
The current is 5 mph
Step-by-step explanation:
The current helps the boat going down stream and hinders going up so it adds to the speed downstream and subtracts going up.
speed downstream is 20miles/40minutes =1 mi per 2 min. Or 30 mph
Speed upstream is
20 miles/ 60 minutes = 1 mile per 3minutes or 20 mph
So if the speed of the boat is the same (s) then downstream the boat travels
S+c =30 mph and s-c =20mph upstream if c is tge current speed
So s=30-c and s=20+c
So. 30-C=20+c
10=2C
5=C
The current is 5 mph
I think the answer would be D
