1.the coordinates of the vertices of triangle abc are a(-1,3), b(1,2) and c(-3,-1). determine the slope of each side of the triangle and use that information to determine if the triangle is a right triangle or not. 2.the coordinates of the vertices of quadrilateral jklm are j(-3,2), k(4,-1), l(2,-5) and m(-5,-2). find the slope of each side of the quadrilateral and determine if the quadrilateral is a parallelogram.

The equation of a parabola is given. y=18x2+4x+20 what are the coordinates of the focus of the parabola?

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
