What the power a when 5^a = 1/125

Mathematics
1 answer:
Advocard [28]2 years ago
3 0

Answer:

a = -3

General Formulas and Concepts:

<u>Algebra I</u>

  • Solving Exponential Equations
  • Exponential Property [Rewrite]: \displaystyle b^{-m} = \frac{1}{b^m}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle 5^a = \frac{1}{125}<em />

<em />

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Rewrite:                                                                                                                \displaystyle 5^a = \frac{1}{5^3}
  2. Rewrite [Exponential Property - Rewrite]:                                                       \displaystyle 5^a = 5^{-3}
  3. Set:                                                                                                                    \displaystyle a = -3

What's the slope-intercept form that passes through the points (0, -1) and (1, 5)?
Rzqust [24]

Answer:

<h2>         y = 6x - 1</h2>

Step-by-step explanation:

\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}

(0, -1)    ⇒     x₁ = 0,  y₁ = -1

(1, 5)     ⇒     x₂ = 1,  y₂ = 5

So the slope:

                     \bold{m=\dfrac{5+1}{1-0}=\dfrac{6}{1}=6}

The slope-intercept form of the equation of line is y = mx + b, where m is the slope and b is the y-intercept of the line.

(0, -1)    ⇒     x₀ = 0,  y₀ = -1      ⇒   b = -1

Therefore:

                 y = 6x - 1          ←  the slope-intercept form of the equation

What is the value of x
slega [8]

Answer:

54

Step-by-step explanation:

A tangent line makes a right angle with the radius to the point of tangency. Hence this triangle is a right triangle, and x° is the complement of 36°:

x° = 90° -36° = 54°

The value of x is 54.
