A certain forest covers an area of 2400 km^2. Suppose that each year this area decreases by 5.75%. What will the area be after 8
kolezko [41]
We have to use the function A(t)= a(1 +/- r)^t
So A is going to be the answer- the area after 8 years. t is going to be 8, because t is time. a is 2400 because that's the starting value. Finally, we're going to turn 5.75% into it's decimal form of .0575. That's going to be r, and because the area is decreasing, we will subtract r from 1.
Our new function is:
A=2400(1-.0575)^8
Simplify a little bit.
A=2400(.9425)^8
Bring .9425 to to power of 8 and then multiply by 2400 because PEDMAS.
A=1494.38366866
The rounded answer is 1494 kilometers squared.

27. To compare the effectiveness of two treatments, researchers conducted a well-designed experiment using a
Firlakuza [10]

In a randomized block design, it is expected treatments are randomly assigned within each block.

<h3>What does a randomized block design imply?</h3>
  • Subjects are divided into blocks based on a specific features such as age, gender, education, etc.
  • Within each block subjects that receive treatment and does who do not are randomly assigned.
  • The treatment in all blocks is the same. For example, if the purpose is to study the effect of medicine all treatment subjects should receive the same medicine and dose.

<h3>What is the purpose of this design?</h3>

The purpose is to minimize the effect of certain factors such as age.

Based on the above, it is expected in this experiment the treatment is randomly assigned to a specific number of subjects within each block.

-2x + y=10. what is the answer to this?<br> y=-1/3x+3​
juin [17]

Answer:

x = - 3, y = 4

Step-by-step explanation:

Given the 2 equations

- 2x + y = 10 → (1)

y = - \frac{1}{3} x + 3 → (2)

Substitute (2) into (1), that is

- 2x - \frac{1}{3} x + 3 = 10 ( multiply through by 3 to clear the fraction )

- 6x - x + 9 = 30

- 7x + 9 = 30 ( subtract 9 from both sides )

- 7x = 21 ( divide both sides by - 7 )

x = - 3

Substitute x = - 3 into (2) for corresponding value of y

y = - \frac{1}{3} (- 3) + 3 = 1 + 3 = 4

solution is x = - 3, y = 4

-3x = 12<br> i really need to know this for my math exam
SIZIF [17.4K]

Answer:

x = -4

Step-by-step explanation:

- 3x = 12

Lets divide both the sides by -3.

=  >  \frac{ - 3x}{ - 3}  =  \frac{12}{ - 3}

=  > x =  - 4
