Answer:
20 N
Step-by-step explanation:
because of newton's second law you will use this equation F=ma which means force= mass*acceleration
so your problem should look like this 5*4=20
To solve this, we have to complete the square of
To do this with halve the and get rid of the x, then get rid of the power on , and then put them all in brackets, and the square the bracket, like so:
becomes
However does not equal
If we expand we get instead.
So to make it equal, all we do is subtract 1.
So when we complete the square of , we get
---------------------------------------------------------
So becomes:
x + 1 = ±√6
x = -1 ± √6
______________________________
Answer:
x = -1 ± √6
I believe it is 1 14/25
39/9
÷
25/9
=
39 × 9
9 × 25
=
351/225
=
351 ÷ 9
225 ÷ 9
=
39/25
OR 1 14/25
Answer: D.
Step-by-step explanation:
You want to cube each term in the parentheses. When you take an exponent to an exponent, you just multiply them. You get (27m^-12). In order to get rid of that negative exponent, you should put a one over the m term and make -12, +12:
Multiply the numerators to get:
You now have:
When you divide exponents, you subtract them. 5 - 12 = -7
You have m^-7 which is the same as 1/m^7. Finally, mulitply that by the 81 we left out to get the answer of D.
