Answer:

1.040

Step-by-step explanation:

log √(120)

= (1/2) log 120

120 = 2³ • 3 • 5

= 0.5(3 log 2 + log 3 + log 5)

Express log 5 in terms of log 2.

log 5 = log (10/2) = log 10 - log 2 = 1 - log 2

= 0.5(3 log 2 + log 3 + 1 - log 2)

= 0.5(2 log 2 + log 3 + 1)

= 0.5(2*0.3010 + 0.4771 + 1)

= 1.03955 or 1.040

I will give a brainliest if ur correct PLEASE HELP!

Gennadij [26K]

C: y= 6

Since they are varying inversely, as one gets larger the other gets smaller and vice-versa.

Since when y=3 when x=4.....

When x gets divided by two y would get multiplied by two instead

So y=6 when x=2

In the figure below, triangle RPQ is similar to triangle RTS.

Iteru [2.4K]

Answer:

Step-by-step explanation:

The rest of the question is the attached figure.

As shown:

triangle RPQ is similar to triangle RTS.

So, the corresponding sides are in proportion.

$\frac{PQ}{TS}= \frac{RP}{RT}$

From the figure:

TS = 36 , RP = 42 AND RT = 28

∴ $\frac{PQ}{36} = \frac{42}{28} \\$

∴ PQ = 36 * 42/28 = 54

<u>So, the distance between P and Q = 54</u>
