Step-by-step explanation:
3. (c) complementary since the sum of the angles is 90°
4. 5x + 95 = 180 ---> 5x = 85 or x = 17 ans (d)
5. 68 + x + 90 = 180
x + 158 = 180
x = 22
ans. (b)
Answer:
25+4+120(2min) = 149
25/149 = 0.16778523489932885906040268456376
= (rounded) 0.17
Answer:
vertex: (5/6,5)
focus: (- 2/3, 5)
axis of symmetry: y = 5
directrix: x = 7/3
Step-by-step explanation:
use the vertex form to determine the values of a.h. and k and use these values to find the direction the parabola opnes, vertex, foucs, axis of symmetry, and directrix
