Answer:
Step-by-step explanation:
The area for a parallelogram is given by the formula:
Where b is the base length and h is the vertical height.
The base length is 16.9 while the vertical height is 8.7. Thus:
Multiply using a calculator:
Answer:
The answer is A.
Step-by-step explanation:
You can make a test by substituing x-coordinate into the equation :
Answer:
The speed is still water is .
Step-by-step explanation:
Dimentionally speaking, speed is distance divided by time. Since, the person is travelling downstream, absolute speed is equal to the sum of current speed and speed of the person regarding current. Both components are constant. That is:
Where:
- Current speed, measured in miles per hour.
- Speed of the person regarding current, measured in miles per hour.
- Distance travelled downstream, measured in miles.
- Time spent on travelling, measured in hours.
Speed in still water occurs when current speed is zero. Then, such variable is obtained after subtracting current speed on both sides of the expression. Hence:
The speed is still water is .
You cannot factor it any further as it is in its simplest factored form. There is no common factor in either the term (25x^2) or (9y^2) that you can pull out so it cannot be simplified. Hope this helps
