Answer:

Option A: f(x) = log_0.98 (n/74)

Step-by-step explanation:

We are told that that the number of species is decreasing by 2% per year.

Thus, number of species each year is 98% or 0.98 of number of species the previous year. .

We are told that there are currently 74 species of amphibians in the rain forest.

Thus, n/74 will represent a fraction of the current number of species.

Thus, the logarithmic function that models the time can be written as;

f(x) = log_0.98 (n/74)

McGwire Aerospace expects to have net cash flow of $12 million. The company forecasts that its operating costs excluding depreci
slava [35]

Based on the net cash flow, the depreciation and amortization, and the tax rate, the expected sales of McGwire Aerospace is $66.67 million.

<h3>What are the expected sales?</h3>

First, find the net income:

= Net cash flow - depreciation and amortization

= 12 - 5

= 7 million

Given this net income, the sales are:

Net income = ( Sales - (Sales x 75%) - 5) x (1 - 40%)

7 / 0.60 = 0.25x - 5

11.67 = 0.25x - 5

0.25x = 16.67

x = 66.67 million

In conclusion, the expected sales are $66.67 million.

Find the circumference of the figure below.<br> (Use T=22/7)
vekshin1

The circumference of a circle with a radius of 12 cm is 75.45 cm

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The circumference of a circle is given by:

Circumference = 2π * radius

Hence:

Circumference = 2(22/7)(12) = 75.45 cm

The circumference of a circle with a radius of 12 cm is 75.45 cm

Answer:

To solve this problem, we can use a system of equations.

We know the quadratic expression has the form

f(t)=at^{2}+bt

Using points (1,12) and (4,0), we can form the following system to find a and b.

12=a+b

0=16a+4b

We need to divide the second equation by -4 and sum both equations

12=a+b\\0=-4a-b

12=-3a\\a=\frac{12}{-3}\\ a=-4

Then, we use this value to find the other variable

12=a+b\\12=-4+b\\b=12+4\\b=16

<h3>Therefore, the quadratic function that models the situation is</h3>

f(t)=-4t^{2} +16t  or  f(t)=-4t(t-4)

According to this expression, after 2 seconds, the height is 16 feet.

f(2)=-4(2)(2-4)=-8(-2)=16
