If a student took seven science classes, his/her at score would be 1200.

<h3>What is a graph?</h3>

A graph is a relationship in which data is presented on the axes of cartesian coordinates. The presentation of the graph must be such that it is easy to read off the graph.

Now we can see that the graph is a plot of SAT scores versus the number of science classes that students take. In this case, the slope would tell us the score per subject of a student in the SAT.

a) The mathematical model that re[resents this graph is;

y =100x + 500

b) The slope of the graph must be obtained by the use of two points thus;

m = y2 - y1/x2 - x1

m = 600 - 500/1 - 0

m = 100

c) Using the relation;

y = mx + c

m = 100

c = 500

y = 100(7) + 500

y = 1200

Thus if a student took seven science classes, his/her at score would be 1200.

One end of a string 4.32 m long is moved up and down with simple harmonic motion at a frequency of 75 Hz . The waves reach the o

max2010maxim [7]

To solve this problem, we will apply the concepts related to the kinematic equations of linear motion, which define speed as the distance traveled per unit of time. Subsequently, the wavelength is defined as the speed of a body at the rate of change of its frequency. Our values are given as,

$\text{Length of the string} = L = 4.32 m$

$\text{Frequency of the wave} = f = 75 Hz$

$\text{Time taken to reach the other end} = t = 0.5 s$

Velocity of the wave,

$V = \frac{L}{t}$

$V = \frac{4.32 m}{0.5s}$

$V = 8.64m/s$

Wavelength of the wave,

$\lambda = \frac{V}{f}$

$\lambda = \frac{8.64m/s}{75Hz}$

$\lambda = 0.1152m$

$\lambda = 11.52cm$

Therefore the wavelength of the waves on the string is 11.53 cm

. A bead of mass m under the influence of gravity slides along a frictionless and massless wire whose height is given by a funct

eduard

Answer:

y = constant

Explanation:

Bodies moving on the surface of Earth are subject to gravity, and they have a potential and kinetic energy. If there is no friction, the sum of the kinetic and potential energy remains constant.

Since potential energy depends on height, changes in altitude affect potential energy. Going higher increases this energy, this is accompanied by a reduction of kinetic energy and speed (since kinetic energy is related to speed). If the body goes down potential energy is reduced, but kinetic energy and speed increase.

For speed to remain constant the kinetic energy must remain constant. For the kinetic energy to remanin constant, the potential energy must remain constant, and for the potential energy to remain constant the height must remain constant.

The fact that something is magnetic can be determined by watching its what?

Delvig [45]

You can check if something is magnetic by watching if it's attracted/repelled by a magnet.

That's the same as saying that the fact that something is magnetic can be determined by watching its behavior.
