Answer:
x = -1
Step-by-step explanation:
4x + 5 = 3x + 4
-5 -5
4x = 3x -1
-3x = -3x
1x = -1
x = -1
Given the equation of the parabola

The vertex of this parabola is placed at point (4,3).
If the equation of the parabola is
then

The coordinates of the parabola focus are

Therefore, the focus is placed at point (4,3,75).
Answer: option D, 0.75 in. above the vertex

Answer:
110.7 cm³ to the nearest tenth
Step-by-step explanation:
The volume V of a cone whose circular base has a radius r and a height h is given as
V = 1/3 πr²h
where π = 22/7
Given the circumference of the circular base as 18.5cm, we must find the radius before we can computed the volume. The relationship between the radius and the circumference is such that the circumference C
= 2πr
hence,
r = C/2π
= 18.5/2π
since the height of the cone is 12.2 cm, the volume V
= 1/3 * π * (18.5/2π)² * 12.2
= 110.71 cm³
