Two jets leave an air base at the same time and travel in opposite directions. One jet travels 80 mi/h faster than the other. If

Vesna [10]

Jet 1 moves with a speed of 672 mi/h, while jet 2 moves with a speed of 672 mi/h + 80mi = 752 mi/h.

Let's say that the rate (or speed) of the slower jet is R, then the rate of the faster jet is:

R + 80mi/h

Now, if we step on any of the two jets (such that we view it as if it doesn't move) the other jet will move with a speed equal to:

S = R + R + 80mi/h

We know that after 8 hours, the to jets are 11,392 mi apart, then we know that:

(R + R + 80mi/h)*8h = 11,392 mi

Now we can solve that for R:

2*R + 80mi/h = 11,392 mi/8h = 1,424 mi/h

R = 1,424 mi/h - 80mi/h)/2 = 672 mi/h

So Jet 1 moves with a speed of 672 mi/h, while jet 2 moves with a speed of 672 mi/h + 80mi = 752 mi/h.

for the simple harmonic motion equation d = 9cos(pi/2)(t), what is the maximum displacement from the equilibrium position ?

belka [17]

Answer:

The maximum displacement from the equilibrium position is 9

Step-by-step explanation:

We are given

equation for the simple harmonic motion equation

$y=9cos(\frac{\pi}{2}t)$

we can use trig formula

$y=Acos(Bt)$

The maximum value of this equation is always A

So, firstly, we will compare and find A

A=9

so,

The maximum displacement from the equilibrium position is 9

Alexus [3.1K]

Answer:

Domain: [-1, 0) U [2]
Range: [0, 1)
A function

Step-by-step explanation:

The domain is the set of x values and the range is the set of y values.

For the relation to the function, each value of x must map onto no more than one value of y.
