Answer:
8 ones, 4 tenths, and 5 hundredths
Step-by-step explanation:
just took the quiz
288J
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
$6.96 $2.9 x 2.4=$6.96
answer is attached on the photo
20 is the answer.
m=0
<em><u>mx²+2x-1=0</u></em>
if x=1/2 then
m(1/2)² +2(1/2)-1=0
m/4+1-1=0
m/4=0
