Answer:
2x^2-3x-5=y
(2x-5)(x+1)=y
(2x-5)(x+1)=0
2x-5=0
2x=5
x=2.5
x+1=0
x=-1
Have a great day!
Step-by-step explanation:
Answer:
The percent change in runs batted in from 2001 to 2008 is 26.47%
Step-by-step explanation:
The number of runs chipper batted in the year 2001 = 102 runs
The number of runs chipper batted in the year 2008 = 75 runs
Here, so the Change in the runs batted
= Runs Batted in year 2001 - Runs batted in the year 2008
= 102 runs - 75 runs = 27 runs
Now, The percentage change in the run = 
= 
or, The percentage change = 26.47%
Hence, the percent change in runs batted in from 2001 to 2008 is 26.47%
The center of the clock is taken as the origin.The clock is a circle with a diameter 10 units.Radius is half the diameter .Radius = 10 ÷2= 5 units.
The clock is divided in four quadrants .On x axis y=0 and on y axis x=0.
When it is 12 o'clock the hour hand is on positive of y axis.Coordinates of the point at 12 o'clock=(0,5)
When it is 3 o 'clock the hour hand is on positive of x axis .Coordinate of the point at 3o'clock is (5,0)
When it is 6 o'clock the hour hand is on negative of y axis .The coordinates of the point at 6o'clock is (0,-5)
At 9o'clock the hour hand is on negative of x axis .The coordinate of the point at 6o'clock is(-5,0)
Area of triangle=1/2bh
