Answer:
See below.
Step-by-step explanation:
Recall the identities:
The area of the circle is 50.27 yards.
4b²+20b+25=0
Divide everything by 4
b²+5b+ 6.25=0
use the quadratic formula
x= (-b+ or - √b²-4ac) /2a
x= (-5 + or - √5²-4*1*6.25) /2(1)
x= -5/2 so
in this case, b= -5/2
Answer:
9 Joules
Step-by-step explanation:
600g to kg is .6kg
15m/s= velocity
KE=mass*velocity
.6*15=9
Domain is -1 and the range is 4.
