Answer:
The y-intercept will always be the vertex of the function.
Step-by-step explanation:
The functions with the following form 
are quadratic equations and have a parabolic form, which means the have a vertex. The x coordinate of the vertex is given by the following expression 
. When b is equal to zero, the vertex of the function will always be the y-intercept, therefore the correct answer is the third one.
Answer:
answer 13.33333 hours h
Step-by-step explanation:
Julia studied 3 1/3 hours during 4 days
this means she studied:
3 1/3 of 4 days of 24 hours
3 1/3 = 9/3 x 1/3 = 10/3
and 4 days of 24 hours is 4 x 24 = 96
there for
10/3 x 96 = (10/1)x32 =320 hours
320/24 hours each day -13.3333

Answer:
Angle C
Step-by-step explanation:
By applying sine rule in the given triangle,
Therefore, sides of the given triangle will be in the same ratio as the sine of the angles.
Since, BD > BC > CD
Therefore, Opposite angles of these sides will be in the same ratio.
∠C > ∠D > ∠B
Largest angle of the triangle is angle C.
