-9-6+12h+40=22
12h+25=22
12h=-23
h=-23/12
Answer:
288J
Step-by-step explanation:
recall the formula for kinetic energy
KE = (1/2) mv²
where m is the mass (= 4kg) and v is the velocity(=12 m/s)
hence
KE = (1/2) (4)(12)² = 288J
We apply our knowledge in variation.
The solution can be seen in the photo
Asuuing yo meant (h,k)=(-5,1/2)
equation is

(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2


if you wanted us to expand
x
²+y^2+10x-y+25.25=1
D because ugh I don’t feel like explaining
