Answer:

x=ln(81) over 2ln(3)

Step-by-step explanation:

Using ln as its base thing instead of log and the formula usually is log over log. Plus you have to bring down the power that way.

likoan [24]

Answer:

  2

Step-by-step explanation:

  To be divisible by 6, an even number must also be divisible by 3. Two of every three even numbers are <em>not</em> divisible by 3, so are not divisible by 6.

Despite control measures, the pigeon population in Winchester is increasing by 10% each year. If there are currently 9,520 pigeo
TEA [102]

Using an exponential function, it is found that there will be 32,866 pigeons in 13 years.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

The initial value and the growth rate are given by:

A(0) = 9520, r = 0.1.

Hence the function is given by:

A(t) = 9520(1.1)^t

Hence in 13 years, the amount of pigeons will be of:

A(13) = 9520(1.1)^{13} = 32866

Which property is demonstrated by the equation (5 + a) + 3 = (a + 5) + 3?
sineoko [7]

Answer:

Communitive Property

Step-by-step explanation:

Commutative property = 2 + 3 = 3 + 2 or 2(3) = 3(2)

Associative Property = (2 x 3) 5 = 2 (3 x 5) or (2 + 3) + 5 = 2 + (3 + 5)

Inverse Property = 2 + (-2) = 0 or (2/1)(½) = 1

Basic Definitions:

<u><em>Commutative Property</em></u> - Gives you the ability to switch the order of the numbers in an expression.

<u><em>Associative Property</em></u> - Let's you move the parenthesis in an expression but not the numbers.

<u><em>Inverse</em></u> - Uses numbers like 0 and 1.

Using these basic definitions and examples, we can summarize that the best answer would be <u>Communitive Property</u>

Equation A y = 4/x + 3 Equation B y = −2x − 4 Which statement best compares the graphs of the two equations?
vampirchik [111]
Elimination
A, they are both linear
linear equations are sometimes given by y=mx+b, equation A, if graphed, produces a hyperbola which is not linear so statement A is false

B they areboth non-linear
equationb is linear so this is false

C equation a is non-linear and equation b is linear
true
C is the answer
