Answer:
y = 52 - 8x
Step-by-step explanation:
If he painted for 3 hours at a rate of 8 square meters per hour, the area painted was:

If after 24 squared meters painted, there are still 28 left, the total area is:

The area still left to paint is initially 52 squared meters and decreases at a rate of 8 square meters per hour, the function that describes the relationship between the area left to paint (y) and number of hours (x) is:
y = 52 - 8x
<span>Part A. How many total yards did Ed run in the first 3 football games.
</span>total yards Ed = 157 + 309 + 172 = 638
<span>Part B. How many more total running yards did Rico have than Ed after the first 3 games of the season?
</span>total yards Rico = 3*total yards Ed = 3*638 = 1914
so Rico has more yards than Ed, 1914 - 638 = 1276, that is, Rico has 1276 more yards than Ed after the 3 first games
Answer:
Step-by-step explanation:
The length of the polar coordinates ray is found using the Pythagorean Theorem: ray length = √( (-1)^2 + (-2)^2 ) = √( 1 + 4) = √5
Because both the x- and the y-coordinates here are negative, the ray is in Quadrant III. Measuring the angle counterclockwise from 0°, we get
Ф = 180° + arctan 2/1, or Ф = 180° + 63.43°, or 243.43°
The desired polar coordinates are (2√2, 243.43°)
After the total distance on the first, second and third days, Patrick had walked 3.45miles
Answer:
The length of fencing is 146 feet.
Step-by-step explanation:
The length of fencing is equal to the perimeter of the rectangle plus 8 times the width of the border between the edge of the pool and the fence. By Geometry, we find that the perimeter (
), measured in feet, is equal to:
(1)
Where:
- Width of the pool, measured in feet.
- Length of the pool, measured in feet.
- Width of the border, measured in feet.
If we know that
,
and
, then the length needed of fencing is:


The length of fencing is 146 feet.
