Answer: r=4

What you do is subtract 12 from itself and from -24 then you have -9r=-36. Then you take -9r and divide it -9 then do the same to -36 and you get 4 :)

An object moves from the position +16 m to the position +47 m in 12 s. What is its total displacement? What is its average veloc

Brrunno [24]

Given that an object moves from the position +16 m to the position +47 m in 12 s. Now we need to find about what is its total displacement and what is its average velocity.

We know that displacement is the object's overall change in position.

So total displacement is given by:

Displacement = (+47) - (+16) = +31

Now velocity is given by ratio of displacement and time so final answer for velocity will be :

$Velocity=\frac{displacement}{time}=\frac{+31}{12}=2.583333$

Which is approx 2.6 m/s.

How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?

Alla [95]

The graph has been moved 3 units downward, making the range change. The range of f(x) is [-5,5], while the range of g(x) is [-8,2]. The picture is of both functions. f(x) is blue, g(x) is red.
