✅To take the lead, your score in the fourth round must be greater than 79.08.
Step-by-step explanation:
If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:
Solve for the value of p
Subtract 232.54 from each side
Positive slope and negative slope so one line is negative and the other is positive
To determine if something is a function or relation, you would look at the x values and determine if every x value has 1 y value. any x vaue with more than one y value would be a relation.
this one would be a function because there only one y value for every x value
Answer: 16 square units
Step-by-step explanation:
let the vertex in quadrant I be (x,y)
then the vertex in quadratnt II is (-x,y)
base of the rectangle = 2x
height of the rectangle = y
Area = xy
= x(12 - x²)
= -x³ + 12x
d(area)/dx = 3x² - 12 = 0 for a maximum of area
3x² = 12
x² = 4
x = ±2
y = 12-4 = 8
So, the largest area = 2 x 8 = 16 square units
