Answer:
16. B
17. B
Step-by-step explanation:
16. The intercept form of the parabola is
where are two x-intercepts.
In your case,
so
To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through
and
17. The vertex form of the parabola equation is
where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so
The vertex is 3 units from the focus, then
The equation of the parabola is
Answer:
Step-by-step explanation:
1). (d). 5°C < 7°C
2). (a). - 8°C < - 3°C
3). (c). 4°C > - 4°C
4). (b). - 10°C > - 16°C
Answer:
D) y = -2
The equation of the perpendicular line to the given line is y = -2
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given point (-3,-2)
In graph the equation of line x = 8 ( parallel to y- axis )
1 x + o y - 8 =0
The equation of the perpendicular line to the given line
b x - a y + k =0
o x - 1 y + k =0 ...(i)
The equation (i) is Paases through the point ( -3,-2)
0 ( -3) -1(-2) + k =0
2 + k =0
k = -2
∴<em>The equation of the perpendicular line to the given line is </em>
<em> put k = -2 in equation (i) </em>
o x - 1 y + k =0
- y +(-2) =0
- y = 2
y = -2
<u><em>Final answer:-</em></u>
∴The equation of the perpendicular line to the given line is y =-2
