Oakville is a fungal disease that infects oak trees scientists have discovered that a single tree in a small forest is infected

with oak wilt they determined that they can use this exponential model to predict the number of trees in the forest that will be affected after t years
F(t)=e^0.4t
Part a
Graph the function F(t)=e^0.4t


Part b
The scientist believe the Forest will be seriously damaged 121 or more of the force 200 Oak trees are infected by oak wilt according to their model how many years will it take for 21 of the trees to be infected type the correct answer in the box use numerals instead of words round your answer to the nearest 10th

It will take approximately ____ years for 21 of the trees to become infected

Part c
Rewrite the exponential model as a logarithmic model that calculates the number of years, g(x), for the number of infected trees to reach a value of X

Part d
Grab the logarithmic function that models the number of years g(x) for the number of infected trees to reach a value of X

Part e
Compare the features of the grass of functions FNG then use your observations to describe the Relationship between the domain and range of the two functions

Answer:

I solved part a

To solve this question, we need to solve an exponential equation, which we do applying the natural logarithm to both sides of the equation, getting that it will take 7.6 years for for 21 of the trees to become infected.

PART C

The logarithmic model is: g(x)= in x/0.4

We are given an exponential function, for the amount of infected trees f(x) after x years.To find the amount years needed for the number of infected trees to reach x, we find the inverse function, applying the natural logarithm.

Which system of equations could be graphed to solve the equation below? log Subscript 0. 5 Baseline x = log Subscript 3 Baseline
Vanyuwa [196]

You can use the fact that two expressions in equality can be considered to be equal to a third variable(not used in given context).

The system of equations that could be graphed to solve the equation given is

  • y = \log_{0.5}(x)\\\\
  • y = \log_3(2+x)

<h3>How can we form a system of equations from an equation?</h3>

Suppose the equation be a = b\\

Let there is a symbol c such that we have a = b = c

It is because a and b are same measure (that is exactly what a = b means)

and we gave another name c to that measure.

Thus, we have

a = c\\b = c

in addition to  a = b\\

<h3>Using the above method to find the system of equations needed</h3>

Since the given equation is log_{0.5}(x) = log_2(2+x)

The 2d graphs are usually expressed as y = f(x) on X-Y plane.

Taking the equation's expressions equal to y, we get

log_{0.5}(x) = log_2(2+x) = y

or, we get system of equations as

y = log_{0.5}(x)\\\\y = log_3{(2 + x)}

Their graph is plotted below. The intersection point of both curves is the solution to the given equation as it satisfies both the equations of the system of equations formed from the given equation.

Thus,

The system of equations that could be graphed to solve the equation given is

  • y = \log_{0.5}(x)\\\\
  • y = \log_3(2+x)

DIA [1.3K]

Answer:

This is the equation for cellular respiration.

Step-by-step explanation:

C6H1206 is glucose. O2 is oxygen. They react to produce 6H20, which is water, and 6CO2, which is carbon dioxide. Energy is also produced which is represented by 2800 kJ. Energy is created in the form of ATP and heat.

Pls solve: 6 - 2/9x = 8
Inga [223]

Answer:

x = -9

Step-by-step explanation:

6 - 2/9x = 8

Subtract 6 from each side

6-6 - 2/9x = 8-6

-2/9 x = 2

Multiply each side by -9/2 to isolate x

-9/2 * -2/9x = 2*-9/2

x = -9
