Answer:

x = 81

Step-by-step explanation:

using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

given

log_{3} x = 4 , then

x = 3^{4} = 81

Use the given information to determine the exact trigonometric value.<br> (in the image attached)
notka56 [123]

Answer:

OPTION B: $ \frac{-2\sqrt{5}}{5} $

Step-by-step explanation:

Given $ cot \theta = -\frac{\sqrt{5}}{2} $

We know that, $ \frac{1}{cot \theta} = tan \theta $

$ \implies tan \theta = \frac{1}{-\frac{\sqrt{5}}{2}} $

$ = -\frac{2}{\sqrt{5}} $

Multiplying and dividing by $ \sqrt{5} $, we get:

$ tan \theta = - \frac{2 \sqrt{5}}{\sqrt{5}\times \sqrt{5}}} $

$ \implies tan \theta = -\frac{2\sqrt{5}}{5} $

Hence, OPTION B is the answer.

IT'S URGENT PLEASEE<br><br> What is the slope of a line perpendicular to the line 2y = 3x - 10?
belka [17]
<h3>Answer:  perpendicular slope is -2/3</h3>

=================================================

Work Shown:

Solve the given equation for y

2y = 3x - 10

y = (3x-10)/2 ..... divide both sides by 2

y = (3x)/2 - 10/2

y = (3/2)x - 5

The equation is in y = mx+b form with m = 3/2 as the slope.

The perpendicular slope is -2/3 because we flip the fraction and the sign from positive to negative.

Note how multiplying the original slope 3/2 and the perpendicular slope -2/3 leads to -1

(3/2)*(-2/3) = -1

This is true for any pair of perpendicular lines, assuming neither line is vertical.

alexdok [17]
In this you have to do 6(total) /(Divided) 2/3. And when you do 6/(2/3) you also have to do KCF(keep, change, flip) and that brings you to 18/2 after multiplying across. So the answer would be 9 people.

I need help with this question
maw [93]
To solve this question we must first find out what is x.

X + x - 4 = 82 degrees

2x - 4 = 82

2x = 86

X = 86/2 = 43.

Here x would be 43 degrees.

We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.
