vertex = (-3, -11)

minimum

Step-by-step explanation:

The vertex of a parabola is its turning point (stationary point).

Therefore, the x-coordinate of the vertex can be determined by differentiating the function, setting it zero and solving for x:

Substitute found value for x into the original function to find the y-coordinate:

Therefore, the vertex is (-3, -11)

As the leading term of the quadratic function () is positive, the parabola will open upwards, so the vertex is its minimum point.

Step-by-step answer

P Answered by Specialist

minimum, coordinates of vertex: (-3,-11)

explanation:

$\sf y =x^2 +6x-2$

x coordinates on vertex:

solving steps:

$\sf \dfrac{-b}{2a}$ $\sf \dfrac{-6}{2(1)}$ $\sf -3$

Find y-coordinate on vertex:

$\sf y =x^2 +6x-2$

$\sf y =(-3)^2 +6(-3)-2$

$\sf y =-11$

$\mathrm{If}\:a < 0,\:\mathrm{then\:the\:vertex\:is\:a\:maximum\:value}$

$\mathrm{If}\:a 0,\:\mathrm{then\:the\:vertex\:is\:a\:minimum\:value}$

coordinates: (-3,-11) thus minimum

If a european swallow flies 15 meters every 1 second how many would kilometers would it fly in 15 minutes

Step-by-step answer

P Answered by PhD

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

David is building wooden picture frames. Each frame requires 3/4 feet of wood. If David started with 12 feet of wood and now has 6 feet of wood remaining, how many pictures frames has he built?

Step-by-step answer

P Answered by PhD

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
