As we know that :
so, over here
plugging the value of i² as -1
Answer:
75 minutes or 1 hour an 15 minutes
Step-by-step explanation:
It takes Martina to run 7.5 minutes for a mile.
Multiply 7.5 by 10 = The minutes for 10 miles
You want the equation for a line that goes through the data points (0, 248) and (5, 277). The slope is ∆y/∆x = (277-248)/(5-0) = 29/5 = 5.8. The first data point is the y-intercept, so your equation in slope-intercept form is
... y = 5.8x + 248 . . . . . . where y is MWh of generation and x is years since 2007.
_____
∆y is read "delta y". It means "the change in y".
