Evaluate log3^8, given log3^2 is equivalent to 0.631
elixir [45]

We will use the followin property of logarithms:


log(a^b) = b log(a)


So, we have


log(3^2) = 2 log(3) = 0.631


If you multiply both sides by 4, you get


8log(3) = log(3^8) = 2.524

Please help! Find the equation of the line and I will mark as brainliest IF answer is right. <3
Hoochie [10]
<h3>Answer:  y = (3/4)x + 13/4</h3>

This is the same as writing y = 0.75x + 3.25

slope is 3/4 = 0.75

y intercept is 13/4 = 3.25

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

Explanation:

One marked point on this line is (-3,1)

Another point is at (1,4)

Let's find the slope of the line through these two points.

m = (y2-y1)/(x2-x1)

m = (4-1)/(1-(-3))

m = (4-1)/(1+3)

m = 3/4

m = 0.75

Now let's use point slope form to find the equation of the line

y - y1 = m(x - x1)

y - 1 = 0.75(x - (-3))

y - 1 = 0.75(x + 3)

y - 1 = 0.75x + 2.25

y = 0.75x + 2.25 + 1

y = 0.75x + 3.25

If you wanted, you can convert those decimal values to fraction form

  • 0.75 = 75/100 = 3/4
  • 3.25 = 325/100 = 13/4

That means the equation

y = 0.75x + 3.25

is the same as

y = (3/4)x + 13/4

jolli1 [7]

Answer:

Step-by-step explanation:

x₁ = 0   ; y₁=0  &

x₂ = 1    ; y₂=2

Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

         =\dfrac{2-0}{1-0}\\\\\\=\dfrac{2}{1}\\\\\\= 2

Slope = 2
