On your expedition, you find a huge area filled with rock formed from lava. the lava seems to have slowly seeped from the crust, is primarily made of basalt, and doesn't show signs of having been explosive. based on this data, which answer is most likely correct about this volcano?

it is from a recent eruption

it formed on a divergent plate boundary

it formed on a subductive zone

it was found using seismographic data

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

it is true

step-by-step explanation:

all the combinations add up i used   calculator

its adding 5.5 each time

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
