Answer:
put a dot on point (2,-4) then go one to the right and one down hope this helps
Step-by-step explanation:
1. Multiply both sides by 2. 7x/2*2<5*2 aka 7x<10
2. Divide both sides by 7. 7x/7<10/7 aka x<(10/7)
3. Your solution should be x<(10/7) or in decimal form x<1.43...
To start this question, we should know what is the atomic number of cobalt. The atomic number (the number of protons) of Cobalt is Z =27.
Now, we know that a Cobalt 60 isotope means an isotope of Cobalt whose Atomic Mass is 60
Thus, in a Cobalt 60 isotope, the number of neutrons in the nucleus are .
From the question we know that the given nuclear mass is 59.933820 u.
Now, the mass defect of Cobalt 60 can be easily calculated by adding the masses of the protons and the neutrons as per our calculations and subtracting the given nuclear mass from it.
Thus,
Mass Defect = (Number of Protons Mass of Proton given in the question) + (Number of Neutrons Mass of Neutron given in the question)-59.933820 u
Mass Defect =
Thus, the required Mass Defect is
In eV, the Mass Defect is

Answer:</h3>
<em>It would be </em><u><em>Choice A</em></u><em>, or </em><u><em>f(x) = (3x-5)(2x-1)</em></u>
<h3>
Step-by-step explanation:</h3>
You would need to factor out the equation to do this. Firstly, ask yourself which two numbers add up to -13 and multiply to 30?
<u>You would get the numbers -3 and -30.</u>
With this, Split -13x in the equation f(x)=6x² -13x+5 as the sum of -3x and -10x.
f(x)=6x² -13x+5 ---> 6x²-3x -10x +5
Next, factor out common terms in the first two terms, then in the last two terms. Do this by finding the greatest common factor or (GCF) in each term pair.
6x²-3x -10x +5 ---> 3x(2x−1) −5(2x−1)
Then, factor out the the common term 2x-1.
3x(2x−1) −5(2x−1) ---> (2x-1)(3x-5)
(2x-1)(3x-5) and (3x-5)(2x-1) are both answers to the equation, it doesn't matter which order the term pairs are in.
<em>***You can have the term pairs in either order due to the communicative property. </em>
<u><em>When checking your answers, this would be</em></u><u><em> Choice A</em></u><u><em> as your final answer</em></u>
<u><em>f(x)= (3x-5)(2x-1)</em></u><u><em>.</em></u>
