The vertex of a parabola is in the first quadrant of a coordinate grid. A line with a negative slope passes through the origin. If the parabola and line intersect at the origin, which statement must be true? The parabola opens downward. The parabola opens upward. The slope of the line is equal to –1. The slope of the line is not equal to –1.

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

vertical=18cm horizontal=18cm hypotenuse=25.5
