Answer:

The phase difference between yA and yB is  \frac{-\pi }{12}

Step-by-step explanation:

Given harmonic modeled as :

yA = 8 sin(2t  - \frac{\pi }{3})         And

yB = 8 sin(2t  - \frac{\pi }{4})

The function as written as :

y = a sin(ωt  - Ф)  where  Ф is phase difference

So , phase difference between yA   and  yB = ( Ф_1 - Ф_2 )

Or phase difference between yA   and  yB = ( -  \frac{\pi }{3} + \frac{\pi }{4} )

Or, phase difference between yA   and  yB = (\frac{-4\pi +3\pi }{12})

I.e phase difference between yA   and  yB =\frac{-\pi }{12}

Hence The phase difference between yA and yB is \frac{-\pi }{12}   Answer

Answer:

  -π/12

Step-by-step explanation:

yA has a phase shift of -π/3; yB has a phase shift of -π/4. The difference between their phases is ...

  -π/3 -(-π/4) = (-4/12 +3/12)π = -π/12

yA lags yB by π/12 radians.

If f (7) = 22, then<br> ff-1(22)) = [?]
lozanna [386]

Answer:

f(f^{-1} (22)) equals 22.

Step-by-step explanation:

For every input in a function, there will be one corresponding output. When taking the output of the function and inserting it as the input to the inverse function of the original, the output will be equivalent to the exact input of the original function. In this case, because f(7)=22, that means f^{-1} (22) will equal 7. Using this knowledge, you can find the value of f(f^{-1} (22)), which will be f(f^{-1} (22)) = f(7)=22, so f(f^{-1} (22)) equals 22.

Find the solution to the systems of equation <br><br> 3x-2y=-9<br> 4x+3y22
eimsori [14]

Answer:

x = 1 and y = 6

Step-by-step explanation:

3x - 2y = -9   ........................... eqn 1

4x + 3y = 22 ........................... eqn 2

to eleminate y, multiply eqn 1 by 3 and eqn 2 by 2

(3x - 2y = -9) × 3

(4x + 3y = 22) × 2

9x - 6y = -27  ........................... eqn 3

8x + 6y = 44  ........................... eqn 4

Add eqn 3 and 4 together and we get

17x = 17

x = 17/17

x = 1

To get y, substitute 1 for x in any of the eqns

taking eqn 4

8(1) + 6y = 44

8 + 6y = 44

6y = 44 - 8

6y = 36

y = 36/6

y = 6

Is 2/3 greater than 2/5?
svetoff [14.1K]
Yes. 2/3 is greater than 2/5. You can check this by cross multiplication or easier just look at the denominator and numerator. In this case the numerator is the same so it's easier in a sense that you need to look at the denominator. Since the denominator 3 is close to the numerator 2 it shows that it's almost a whole unlike the other fraction. You can also convert each fraction to decimals and compare it which is also easy. Just divide the numerator by the denominator and you've got a decimal. Hope this helps!

Write the standard form of the equation of the line that passes through (-2, -3) and (2,-5).
Naily [24]

Answer:

y= -1/2x-4

Step-by-step explanation:

By standard form, I'm assuming you mean slope-intercept form, which is y=mx+b. First, we need to find m, or the slope. To do this, we need to plug it into this equation: m= y2-y1/x2-x1. We can rewrite this with our two points, so we make it into m= -5+3/2+2. I did plus signs because if you subtract a negative number from a number, it has the same effect as addition does. Now, we have m= -2/4, which we can simplify to -1/2. Now, we have y=-1/2x+?. Now, let's plug in the numbers in slope-intercept form. I'll choose the ordered pair (-2, -3) for this example. Now that I've plugged the numbers in y=mx+b form (slope-intercept form), we have -3=(-1/2⋅-2)+b. Now, we solve it. First, we do the problem in the parenthesis, from that, we get 1. Now, we have -3=1+b, let's subtract 1 from both sides. Now, we have -4=b. That means our y-intercept is -4. Let's plug this back in the equation. We get y=-1/2x-4. I hope this helps!

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆

Answer: 390$

Explanation:

Lets say each drives 9 miles per gallon, and each costs 6.50

540 / 9 = 60

60 x 6.5 = 390$

I hope this helped!
