A and b are positive integers and a–b = 3. Evaluate the following:<br> 27/1/3 b/9/ 1/2 a

DaniilM [7]

Answer:

$\dfrac{1}{27}$

Step-by-step explanation:

Given that,

a-b = 3

We need to find the value of $\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}$ .

We know that,

$27=3^3\\\\9=3^2$

So,

$\dfrac{27^{\dfrac{1}{3}b}}{9^{\dfrac{1}{2}a}}=\dfrac{3^3^({\dfrac{1}{3}b})}{3^2^{\dfrac{1}{2}a}}\\\\=\dfrac{3^b}{3^a}$

We know that : $\dfrac{x^p}{x^q}=x^{p-q}$

So,

$\dfrac{3^b}{3^a}=3^{b-a}$

Since, b-a = -3. So,

$3^{b-a}=3^{-3}\\\\=\dfrac{1}{3^3}\\\\=\dfrac{1}{27}$

So, the value of the given expression is equal to $\dfrac{1}{27}$ .

The question is below, plz answer, will give brainliest

By comparing the right triangle ABC with the triangle XYZ, we will see that:

AC = 5
BC = 10.

<h3>How to find the given segments?</h3>

So we know that the largest triangle is a dilation of scale factor 2 of the smaller one.

Also, remember that for right triangle we have the relation:

Tan(θ) = (opposite cathetus)/(adjacent cathetus).

Now, the problem tells us that:

tan(x) = 5/2.5

For the angle x, the adjacent cathetus is XY, and the opposite cathetus is YZ.

Then we have:

YZ = 5

XY = 2.5

Knowing that the correspondent sides in the larger triangle will be 2 times the above ones, we can see that:

AC = 2*XY = 2*2.5 = 5

CB = 2*YZ = 2*5 = 10

ASAP! equation of the line in slope-intercept form

Crazy boy [7]

Answer:

y = -1/3x + 6 $\frac{2}{3}$

Step-by-step explanation:

First, change the original equation to slope intercept form:

y + 4 = 3x

y = 3x - 4

Now, find the slope of the perpendicular line. It will be the opposite reciprocal:

The opposite reciprocal of 3 is -1/3.

Next, plug this into the slope intercept equation along with the given point, so we can solve for b:

y = mx + b

6 = -1/3(2) + b

6 = -2/3 + b

6.67 = b

So, the equation will be y = -1/3x + 6 $\frac{2}{3}$
