Answer:
y = 2/3
Step-by-step explanation:
first, you have to get y by itself. you do that by adding 2 to both sides, making the equation
3y = 2. next, you divide both sides by 3, to finish getting y by itself, making the equation y = 2/3
Answer:
x=3
Step-by-step explanation:
x^2-9
bcos g(-1)=-1
f(g)=x^2+9(-1)=0
x^2-9=0
x^2=9
x=√9
x=3
1) √72z² = 6z √2 B.
2 * 6 * 6 = 72
2) C. √6
3 * 3 √6 - 4 * 2 √6 = 9√6 - 8√6 = √6
<h3>Answer:</h3>
48 mph
<h3>Explanation:</h3>
The rate in miles per second can be converted to the rate in miles per hour by multiplying by the number of seconds in an hour:
Explanation:
Mass of boy = 40 kg
Mass of box = 20 kg
Total mass = 60 kg
Initial potential energy = 0 (since height would be 0 initially)
Final potential energy = mgh
Taking g as 10 m/s²,
=> 60 × 10 × 15
= 9,000 J
So, work done = final potential energy - initial potential energy
= 9,000 J
Power = Work/Time
=> Power = 9000/25
=> Power = 360 J/s
or 360 watt.
