Area of the rhombus:
A = d 1 · d 2 / 2
72 = 16 · d 2 / 2
72 = 8 · d 2
d 2 = 72 : 8
Answer: d 2 = 9 yd
Answer:
√b/a
Step-by-step explanation:
Here, the given equation is,
x^2+y^2+px+6y-3=0
By copairing it with x^2+y^2+2gx+2fy+c=0, we get,
2g=p or, g=p/2
2f=6 or, f=3
c=-3
now the radius is,
r^2=g^2+f^2-c
or, 4^2=(p/2)^2 +3^2 -(-3)
or, 16= p^2/4 +9+3
or, 16-9-3=p^2/4
or p^2/4=4
or, p^2=4×4
or p^2=4^2
or p=4
therefore the rewuired value of p is 4.
I couldn’t figure it out. I have been trying to
(480/1600)×100=30
Or
(480×100)/1600=30
.°.30% were satisfied with the car.
