Answer:

10

Step-by-step explanation:

So it's a 30-60-90 triangle, which you can either find with trig or if you remember this rule you can find it quick. In the pic n is 5, so to find x you just follow the rule and multiple 5 times 2, which is 10. Then the other side of the triangle would be $5\sqrt{3}$ . This rule applies to any 30-60-90 triangle.

Which expression can be used to approximate the expression below, for all positive numbers a, b, and x, where a. 1 and b.

<h2>The required "option A) $\dfrac{\log_{b}x}{\log_{b}a}$ " is correct.</h2>

Step-by-step explanation:

We have,

$\log _{a}x$

To find, the value of $\log _{a}x$ = ?

∴ $\log _{a}x$ , where a, b and x are positive

a ≠ 1 and b ≠ 1

We know that,

The logarithm identity,

$\log_{p}m=\dfrac{\log_{y}m}{\log_{y}p}$

∴ $\log _{a}x$ = $\dfrac{\log_{b}x}{\log_{b}a}$

Where, b is the common base of logarithm

∴ The value of $\log _{a}x$ = $\dfrac{\log_{b}x}{\log_{b}a}$

Thus, the required option A) $\dfrac{\log_{b}x}{\log_{b}a}$ is correct.

A scientist measures the change in the temperature of a chemical solution at the start of the experiment, the solution is at a t

ArbitrLikvidat [17]

Answer:

The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C

Step-by-step explanation:

From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.

Now, if the temperature increases by 2.9 C each hour,

Then, after 3 hours, the temperature of the chemical solution would have increased by

2.9 C/h × 3 h

8.7 C

Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.

The temperature of the chemical solution after 3 hours will be

-14.96 C + 8.7 C

= -6.26 C

≅ -6 C (to the nearest whole degree)
