Answer:

Exponential form is log_{3}(3^{4}) = 4.

Step-by-step explanation:

Given : log_{3}(81) =4.

To find : Represent in exponential form .

Solution : We have given that  log_{3}(8) =4.

We can write as 81 = 3^{4}.

By the logarithm form  log_{a}(a^{n}) =n.

Then ,

log_{3}(3^{4}) = 4

Therefore, Exponential form is log_{3}(3^{4}) = 4.

The equation of the graph shown plotted in the coordinate plane is y = x + 4. What statement is not true about this graph? A. Ea
frez [133]

Definately option C

  • As it's mentioned y=x+4 it must be function
  • So in function every domain has its unique range.
  • Hence here the slope is not constant

As

The graph shown is a parabola which is not y=x+4

So option C is wrong

When flying at an altitude of 5 miles, the lines of sight to the horizon looking north and south make about a 173.7 degree angle
oksian1 [2.3K]
5 miles high is one of the sides of a triangle depending on accuracy level
h^2=x^2+y^2
we don't have 2 distances
Tan A=O/a
O=a tan A
We solve for O because the angle is at the top of the line going up and we want the opposite angle that is along the ground
O=5×tan(173.7/2)=90.854033512
The distance he can see is:
90.85*2~181.7 miles

Now we need to find the distance between lines:
The north south distance between each line is 69 miles
thus the number of degrees he will see will be:
181.7/69
=2 19/30

Determine whether the improper integral converges or diverges, and find the value of each that converges.
kiruha [24]

Answer:

Diverges

Step-by-step explanation:

For the improper integral to converge the limit must exist, if the limit does not exist or is infinite the integral diverges;

\int\limits^a_b {(2x+4)/x^2+4x+5} \, dx#

Where a and be is infinity

The solution of this is infinity and therefore the integral diverges because the first expression is undefined because ∞/∞, the second term is 4·∞ which is infinity and infinity added to any number is infinity
