What change(s) should Sylvia make to the equation to find the value of t in the above scenario?
finlep [7]

Answer:

Option (D).

Step-by-step explanation:

Initial population of the deer P_{0} = 4800

Decrease in the population of the deer after every 8 years = \frac{1}{2}\times (\text{Initial population})

Decrease in population is an exponential process, so the expression representing population will be,

P_{t}=P_{0}(1-r)^x

Where P_{t} is the population after 'x' slots of 8 years.

r = fraction of decrease in the population

x = \frac{\text{Number of years}}{8}

By substituting the values of r and x in the expression,

P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}

P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}

Therefore, Sylvia should do few corrections in her expression.

(8) should be replaced by (\frac{1}{2}) and \frac{t}{2} should be replaced by \frac{t}{8}.

Option D. will be the answer.

If f(x) = (x + 9 and g(x) = --6, which describes the range of (f + g)(x)?
S_A_V [24]

Given:

Consider the below figure attached with this question.

To find:

The value of (f+g)(x).

Solution:

The given functions are:

f(x)=|x|+9

g(x)=-6

Now,

(f+g)(x)=f(x)+g(x)

(f+g)(x)=|x|+9+(-6)

(f+g)(x)=|x|+9-6

(f+g)(x)=|x|+3

We know that,

|x|\geq 0

Adding 3 on both sides, we get

|x|+3\geq 0+3

(f+g)(x)\geq 3

So, (f+g)(x)\geq 3 for all values of x.

Hence, the correct option is A.
