Answer:

w<0 or w>9

Step-by-step explanation:

+3>

3w+2

Let's find the critical points of the inequality.

3w+2

3w+2=29(Multiply both sides by w)

3w2+2w=29w(Multiply both sides by w)

3w2+2w−29w=29w−29w(Subtract 29w from both sides)

3w2−27w=0

3w(w−9)=0(Factor left side of equation)

3w=0 or w−9=0(Set factors equal to 0)

Answer:

Explanation:

First take LCM

Now you can remove the denominator(LCM) because it is on both sides.

So, we get

2 + 3w > 29

3w > 27

w>9

In this way, we get the answer.

Can someone PLEASE explain how to do this problem for me: Write 54c^2/3 in radical form.

Interesting, middle school math? Wow.

Use the formula a^x/n= $\sqrt[n]{a}^x$

Making the equation look like this 54 $\sqrt[3]{c}^2$

(54c)^2/3 is

$\sqrt[3]{(54c)^2}$

Anna007 [38]

Answer:

x = 3.748

Step-by-step explanation:

this problem requires logs

$log_{7} 30 = x-2$

x = 2 + log_7 (30) or 3.7479

What you do is you put three on top because a=3 and then you add 5 and 3 to get 8 for the bottom and you get a answer of 3/8 which you cannot simplify with whole numbers

An analog signal with a bandwidth of 36MHz is sampled at a frequency (fs) of 36,000,000 samples per second during the ADC (analo

Elza [17]

Answer:

The signal would have experienced aliasing.

Step-by-step explanation:

Given that:

the bandwidth of the signal $f_m$ = 36MHz

= 36 × 10⁶ Hz

The sampling frequency $f_s$ = 36 × 10⁶ Hz

Suppose the sampling frequency is equivalent to the bandwidth of the signal, then aliasing will occur.

Therefore, according to the Nyquist criteria;

Nyquist criteria posit that if the sampling frequency is more above twice the maximum frequency to be sampled, a repeating waveform can be accurately reconstructed.

∴

By Nyquist criteria, for perfect reconstruction of an original signal, i.e. the received signal without aliasing effect;

Then,

$f_s \geq 2f_m$

∴

The signal would have experienced aliasing.
