WILL mark BRAINLIEST <br> WHICH OF THE FOLLOWING COULD BE THE EQUATION OF THE FUNCTION BELOW?
AysviL [449]

Answer:

y = 0.5cos(4(x+π/2)) -2

Step-by-step explanation:

The centerline of the oscillation is at -2, so only the 2nd and 4th choices are viable.

The multiplier of x is computed from (2π)/period. One period is π/2, so the multiplier of x is ...

... 2π/(π/2) = 4 . . . . . matching the 2nd selection.

The horizontal offset in the second equation (π/2) is of no consequence, as it is one full period of the function.

The peak-to-peak amplitude of the oscillation is 1 unit, so the multiplier of the cosine function (which usually has a peak-to-peak value of 2 units) is 0.5. Every offered answer has that characteristic.

The appropriate choice is the 2nd one:

... y = 0.5cos(4(x+π/2)) -2

Sum of three like fractions is 18/11. the first 2 fractions are 1/11 and 9/11. find the third fraction.
Mariulka [41]

Answer:

\frac{8}{11}

Step-by-step explanation:

Since the fractions are like, their denominators are 11, then

consider the values that sum to give 18 , that is

1 + 9 + ? = 18

10 + ? = 18 ( subtract 10 from both sides )

? = 8

Then the third fraction is \frac{8}{11}

Solve the system algebraically.<br> 3x - 2y - 1 = 0 y = 5x + 4 <br> What is the solution?
Bogdan [553]

Answer:

x=\frac{-9}{7}

y=\frac{-17}{7}

Step-by-step explanation:

We have been given the equation:

3x-2y-1=0

And y=5x+4

Second equation can be rewritten as:

5x-y=-4

We will solve the equations:

3x-2y=1      (1)

5x-y=-4       (2)

Multiply equation (1) by 5 and equation (2) by 3 we get:

15x-10y=5      (3)

15x-3y=-12       (4)

Now, subtract (4) from (3) we get:

-7y=17

y=\frac{-17}{7}

Now substitute y=\frac{-17}{7} in equation (1) we get:

3x-2{\frac{-17}{7}}=1

3x+\frac{34}{7}=1

21x=-27

x=\frac[-27}{21}

x=\frac{-9}{7}
