Answer:
The vertex and the axis of symmetry in the attached figure
Step-by-step explanation:
we know that
The equation of a vertical parabola written in vertex form is equal to

where
a is the leading coefficient
(h,k) is the vertex of the parabola
and the equation of the axis of symmetry is equal to the x-coordinate of the vertex

In this problem
we have

This is a vertical parabola written in vertex form open upward
The vertex is a minimum
where
the vertex is the point (5,-7)
the x-coordinate of the vertex is 5
so
the equation of the axis of symmetry is equal to

The graph in the attached figure
Answer:
a subtraction sign belongs in the circle
Step-by-step explanation:
[4+8×3]÷(16-2) is:
[(4+24) ÷ 14] = 28/14 = 2
Answer:
k = -11
Step-by-step explanation:
Let 
And x+2 is a factor of p(x)
Let x+2 = 0 => x = -2
Putting in p(x)
=> p(-2) = 
<u><em>By remainder theorem, Remainder will be zero</em></u>
=> 0 = -8-6(4)-2k+10
=> 0 = -8-24+10-2k
=> 0 = -22-2k
=> -2k = 22
Dividing both sides by -2
=> k = -11
Answer:
C. 80
Step-by-step explanation:
m angle 1 = ½×(105+55)= ½× 160= 80°
A=A1+A2+A3+A4
A1 (the base)=5×15/2=37.5
A2=A3 (the sides)
A2=15×9/2=67.5
A4=17×15/2=127.5
A=37.5+67.5×2+127.5
A=300
