I think the answer here would be D. When it rains several inches, the water level of the lake increases, because the word Causation means: the relationship between cause and effect; causality. If it rains a lot, it will cause the lake to increase. ( if help on ur exam use Socratic and brainly!❤️) Hope you do well!!!

A constant force F=6i+8j?6k moves an object along a straight line from point (6, 0, -10) to point (-6, 7, 2).
Arisa [49]

Answer:

The work done is 56 joules.

Step-by-step explanation:

The work done by a force is defined to be the product of the component of the force along \vec{D} and the distance moved:

W=\vec{F}\cdot \vec{D}

For our case the displacement vector is

\vec{D}=\langle -6,7,2\rangle- \langle 6,0,-10\rangle\\\vec{D}=\langle -12,7,12\rangle

And the work done is

W=\langle 6,8,6\rangle \cdot\langle -12,7,12\rangle\\W=6\left(-12\right)+8\cdot \:7+6\cdot \:12\\W=56

If the unit of length is meters and the magnitude of the force is measured in newtons,then the work done is 56 joules.

Afina-wow [57]

The system of equations are:

$12p + $3a = $258

a - p = 6

Where:

  • a = phone accessories
  • p = phone

<h3>What are the system of equations?</h3>

Two linear equations would be derived from the question. The linear equations would be a function of the phones and accessories sold. These equations are known as simultaneous equations and they would have to be solved together in order to determine the required values.
