We first need to write the function in standard form.
y = -x^2 - 7x + 18
To find the axis of symmetry, we do -b/2a
The a and b are the coefficients of the x values.
So a would be -1 since -x is same as -1x
Follow that, b would be -7.
Then just plug the values in. - (-7)/2(-1) = -7/2
The axis of symmetry is -7/2
Answer:
A clear conscience means a conscience void of the guilt of a wrong done. This simple meaning can be extended to both God and man. With a clear conscience, we can stand before God and men with no accusation coming to obstruct our relationship with them.
The correct answer is - all of these contributed.
The sediments in the lagoons come from multiple different sources. The rivers and streams from the mainland, the sediments brought by the wind, and even the ocean waves that manage to get over the spit occasionally.
The biggest influence in the deposition of the sediments in the lagoons though is by the rivers and the streams from the mainland. They carry sediments with them constantly, and the amount of those sediments is also on a high level, in fact they bring in so much sediments that they have actually built the lagoon itself.
The wind and the ocean waves that manage to get over the spit have much lesser influence in the total deposition of sediments, but still they do in some part, and it shouldn't be put aside.
The combination of the three different sources, with different types of sediments brought to the lagoon by each of them, gives the lagoons a beautiful and unique appearance.
The kinetic energy of an object is given by:
Kinetic energy = 1/2 * mass * velocity²
If the kinetic energy of the pendulum at the top of its swing is 0, then this tells us that the velocity of the pendulum at that point is 0. All of the kinetic energy is converted to potential energy, and the pendulum starts moving in the opposite direction after this point in time.
