The price for each pound of tuna is the same. Each pound costs $5. For 10 lbs of tuna, it would be $50.

Step-by-step explanation:

For these kind of questions, you can either find the pattern in the information given or you find the unit price.

Pattern: Check the numbers to see if there are any patterns happening. 3 mutlpiled by 5 gets you 15, 7 muliplied by 5 gets you 35, and 9 multipled by 5 gets you 45.

Unit Price: You would need to find the price for one item, or in this case, one pound. If 3 lbs is $15 dollars you would do 15/3, 15 divided by 3/total price divided by pounds, so you would get $5. You can also change the denominator to 1 and to do this you would divide the 3 by 3 to get 1 and what you do to the bottom, you do to the top so you also divide 15 by 3 and you would get 5. In conclusion, 5/1 which is 5 dollars for one pound.

The arrows represent the number it goes in btw. I'm not too good with explaining things so let me know if you need clarifications on anything and I also personally recommend the unit price method since it isn't easy to spot a pattern with harder questions. Tell me if I'm wrong please so I can go back and look:)

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u
