If you would like to transform the following phrase into a math expression, you can do it like this:
8 less than a number is no more than 14 and no less than 5
a number ... n
8 less ... - 8
no more than 14 .... < 14
no less than 5 ... > 5
<span><span><span>Now you just have to put this together: 5 < n - 8 < 14
If 5 and 14 are included: 5 <= n - 8 <= 14
</span></span></span>
Answer:
Step-by-step explanation:
![[ \ (a+b)^2 = (a+b)(a+b) \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20%28a%2Bb%29%5E2%20%3D%20%28a%2Bb%29%28a%2Bb%29%20%5C%20%5D)
![[ \ a^2 - b^2 = (a-b)(a+b) \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20a%5E2%20-%20b%5E2%20%3D%20%28a-b%29%28a%2Bb%29%20%5C%20%5D)
It’s the 9 because it’s 3 times 3
The number is written as

To evaluate the power of ten, just remember that 10 to the power of n is a one followed by n zeroes, so ten to the sixth power is a one followed by six zeroes:

So, the number is

When you multiply a number by a power of ten, you simply add the same number of zeroes after the number. So, in this case, you only need to add six zeroes after 93:

which is 93 millions.
A : 10000 J
B: 625 J
C: 2500 J
Step-by-step explanation:
Step 1:
We know that ,
Kinetic Energy is given by ((1/2) × m × V²) J
where m = Mass of substance
V = Velocity
Step 2:
In first case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 20 ×20
= 10000 J
In second case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 5 ×5
= 625 J
In Third case, m= 50 kg, V=10 m/s
Kinetic energy = 0.5 × 50 × 10 ×10
= 2500 J
