Solve : 9x-28 = 0

Add 28 to both sides of the equation :

9x = 28

Divide both sides of the equation by 9:

x = 28/9 = 3.111

Answer:

2 < x < 3

Step-by-step explanation:

4x - 4 < 8 AND 9x + 5 > 23

4x < 12 AND 9x > 18

x < 3 AND x > 2 so the answer is 2 < x < 3.

Help ASAP!!<br>Using the graphed function above, find the following

Alenkinab [10]

Answer:

Maximum: 1, Minimum: -3, Midline y = -1, Amplitude = 4, Period = $\pi$ , Frequency $\displaystyle =\frac{1}{\pi}$ , equation : $f(x)=-4cos(2x)+1$

Step-by-step explanation:

<u>Sinusoid Functions</u>

It refers to the oscillating functions like the sine or cosine which range from a minimum and maximum value periodically.

The graph shown can give us all the information we need to answer these questions:

Maximum: 1

Minimum: -3

The midline goes through the center value (mean) of the max and min values, i.e.

Equation of the midline:

$\displaystyle y=\frac{1-3}{2}=-1$

Amplitude is the difference between the maximum and minimum values

$A=1-(-3)=4$

The period is the time it takes to complete a cycle. We can see the minimum value is first reached at x=0 and next at $x=\pi$

Thus the period is

$T=\pi$

The frequency is the reciprocal of the period:

$\displaystyle f=\frac{1}{T}=\frac{1}{\pi}$

The angular frequency is

$\displaystyle w=2\pi f=\frac{2\pi }{\pi}=2$

The equation of the function is a negative cosine (since it starts at the minimum) or a shifted sine or cosine. We'll choose the negative cosine, knowing all the parameters:

$f(x)=-4cos(2x)+1$

somebody help pls Complete the table by filling in the multiplicative inverse of the numbers below 2,1/5,-4,

Yakvenalex [24]

Answer:

Suppose we have a random number A.

The multiplicative inverse of A is a number X such that:

A*X = 1

When we work with real numbers, X = 1/A

Then:

A*(1/A) = A/A = 1

This means that (1/A) is the multiplicative inverse of A.

Where we need to have A ≠ 0, because we can not divide by 0.

Now we want to find the multiplicative inverse of the numbers:

2: Here the inverse is (1/2) = 0.5

1/5: Here the inverse is (1/(1/5)) = (5/1) = 5

-4: Herre the inverse is (1/(-4)) = -(1/4) = -0.25

Consider
.. X = {1, 2, 3, 4}, x = 4
.. Y = {2, 3, 4, 5, 6}, y = 5, w = 3
The elements in X or Y (X ∪ Y) are {1, 2, 3, 4, 5, 6}, n = 6.
.. n = 6 = 4 + 5 - 3

Note that if we just add x and y, we count the common elements twice. In order to just count the common elements once, we need to subtract that count from the total of x and y.

selection B is appropriate.
