Answer: The plumber worked 7/8 hours in total.
Step-by-step explanation:
There is 360 degrees in a full revolution.
There are 7 sides/edges/vertices in a heptagon.
360/7 = 51.42857143
The degree of an angle in a regular heptagon is thus 51.42857143 degrees.
Step-by-step explanation:
can you send a new picture I can't see the whole problem
68 degrees because they’re vertical angles
Answer:
A and B
Step-by-step explanation:
The minimum occurs at the turning point ( vertex )
The coordinates of the vertex are (1, - 2 ) → A
The x- intercepts are the points where the graph crosses the x- axis
This occurs at (3, 0 ) and (- 1, 0 ) → B
The axis of symmetry is a vertical line passing through the vertex
Equation of axis of symmetry is x = 1 , not y = - 2
(1, - 2 ) is a minimum not a maximum , see above
