Answer: The axis of symmetry is x=1.
Explanation:
The given function is,

The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.
The axis of symmetry of a parabolic function
is a vertical line,

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,



Therefore, the axis of symmetry is x=1.
Answer:
37 meters
Step-by-step explanation:
The equation for the area of a trapezoid is
.
Here,
,
, and
is unknown.




The height of the trapezoid is the width of the garden, so the garden is 37 meters wide.
Answer:
.0625
Step-by-step explanation:
Answer:
A) x = ±2i√3
Step-by-step explanation:
We presume you want to find x such that f(x) = 0.
Divide by 13:
x² + 12 = 0
Subtract 12:
x² = -12
Take the square root:
x = ±i√12 = ±2i√3
You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2
