Answer:
2.389 x 10^5
Step-by-step explanation:
First, write both numbers out. Move the decimal point right however many times the exponent says. For 8.9, we move the decimal right 3 times, and we would move it right 5 times for 2.3.
230000
<u>+ 8900</u>
238900
Now let's convert this to scientific form. The beginning number in scientific form has to be between 1 and 10, so move the decimal point left until you get a number that fits. Here, we will move it 5 times.
2.38900
Because we've moved it left 5 times, we make the exponent 5.
Answer:n=3/2
Step-by-step explanation:
(√2)^3=2^n
(2^(1/2))^3=2^n
2^(3/2)=2^n
The same base
Therefore n=3/2
Answer: a = (V^2 - v^2)/2s
Step-by-step explanation:
The equation for the final velocity is:
V^2 = v^2 + 2*a*s
where V is the final velocity, v is the initial velocity, a is the acceleration and s is the distance.
Now, we want to solve this formula for a, this would mean isolate a in one side of the equation, this is pretty simple, first we pass subtract v^2 in both sides.
V^2 - v^2 = v^2 + 2*a*s - v^2
V^2 - v^2 = 2*a*s
now we can divide by 2*s in both sides:
(V^2 - v^2)/2s = 2*a*s/2s = a
a = (V^2 - v^2)/2s
