The correct answer for the question that is being presented above is this one: "The axis of symmetry is to the left of zero." The a value of a function in the form f(x) = ax2 + bx + c is negative. The statement must be true is this The axis of symmetry is to the left of zero.<span>

For this case we have a standard quadratic equation of the form:
 f (x) = ax ^ 2 + bx + c&#10;
 As the function is negative then the following is true:
 a \ \textless \ 1&#10;
 Therefore, when the leading coefficient is less than one then:
 1) The parable opens down.
 2) The cutting points with the x axis can be positive or negative
 3) The cutoff point with the y axis can be positive or negative
 4) The axis of symmetry can be to the right or to the left of zero.
 5) The vertex of the parabola is a maximum and this is because the second derivative is negative.

 Answer:
 
The vertex is a maximum.

One line is y = 3x + 2 and the other line goes through the point (0, -5). Write equation of line.
Lady_Fox [76]

Answer:

y=3x-4 is the slope-intercept form of the equation of a line.  It is in the form y=mx+b.

    m is the slope (often called "rise over run") and b is the y-intercept (the point where x=0).

The y-intercept is the point (0,-4).

We need one other point.  This is where finding easy calculations pays off.  How about where x=2, y=(3)(2)-4 = 2.

That's the point (2,2).

You are hiking and are trying to determine how far away the nearest cabin is, which happens to be due north from your current po
Margaret [11]

Answer:

336.7 yards away from the cabin....

Step-by-step explanation:

The angle 30.7° is also the angle of the upper interior angle of the triangle (near the cabin)

Use the tan function:

opposite = 200 yards

adjacent = x

tan(30.7°) = (opposite / adjacent)

tan(30.7°) = 200 yards/x

x * tan(30.7°) = 200 yards

x = 200 yards/ tan(30.7°)

x= 200/ 0.594

x = 336.7 yards.

336.7 yards away from the cabin....
