Answer:
c)<em> y = 80 (2.5)^x</em>
Explanation:
The first term is 80 and the common ratio is 2.5 because every term is being multiplied by 2.5. To figure this out when it is not
obvious, divide the 2nd term by the first term. The equation is y = 80(2.5)^x
We can check the answers by putting the values in the formula
y = 80(2.5)^1
= 200
y = 80(2.5)^2
= 80 x 6.25
= 500
y = 80(2.5)^3
= 80 x 15.625
= 1250
y = 80(2.5)^4
= 80 x 39.0625
= 3125

I would have to say that the answer to this question is none of the above. The answers given to this multiple choice question are some of the branches of biology. If the question asked for the branches of biology then the answer would be all of the above.</span>
Answer:
c) removing fluoride ions.
Explanation:
Hello!
In this case, for this solubility product problem, it is very convenient to write the undergoing ionization reaction:
In such a way, via the Le Chatelier's principle, we remember that the addition of reactants shifts the reaction towards products, adding products shifts the reaction towards reactants, removing reactants shifts the reaction towards reactants and removing products shifts the reaction towards products. In means, that the best way to shift this reaction away from solid calcium fluoride and toward the dissolved ions is c) removing fluoride ions, because it is a product and its removal favors the formation of more products.
Best regards!
False, because heat travels from warm to cool objects, so if both have the same temp ( ie: no temp difference) heat will not be transferred between them.
Answer:
Explanation:
It may not make any difference. The information missing is the radius of the planet.
However for the purposes of the question, let us assume that it is roughly the same diameter of the earth. Then the weight of anyone would increase if the mass is all that changes..
The formula governing your weight is F = G * m1 *m2 / r^2. If m1 is the mass of the planet and it increases a lot then m2 (you) should increase. The question is done by a proportion.
