The population of the endangered species in the habitat will drop below 30 after approximately 39.2 years, given a 4% decrease rate per year and initial population of 143.

We can use the exponential decay formula to model the population of the endangered species:

P = P₀ * e^(-rt)

where P is the population at time t, P₀ is the initial population, r is the annual rate of decrease (expressed as a decimal), and t is the time elapsed (in years).

We are given that the population decreases at a rate of 4% per year, so r = 0.04. We are also given that the current population is 143, so P₀ = 143. We want to find the time t when the population drops below 30, so P = 30.

Substituting these values into the formula, we get:

30 = 143 * e^(-0.04t)

Dividing both sides by 143, we get:

e^(-0.04t) = 0.2098

Taking the natural logarithm of both sides, we get:

ln(e^(-0.04t)) = ln(0.2098)

Simplifying, we get:

-0.04t = -1.5671

Dividing both sides by -0.04, we get:

t ≈ 39.2

Therefore, the population of the endangered species in the habitat will drop below 30 in about 39.2 years. We round this to the nearest tenth to get our final answer: after approximately 39.2 years.

Answer:

\(\frac{dy}{dx}=y'=\frac{\sec^2(x-y)(8+x^2)^2+2xy}{(8+x^2)(1+\sec^2(x-y)(8+x^2))}\)

Step-by-step explanation:

So we have the equation:

\(\tan(x-y)=\frac{y}{8+x^2}\)

And we want to find dy/dx.

So, let's take the derivative of both sides:

\(\frac{d}{dx}[\tan(x-y)]=\frac{d}{dx}[\frac{y}{8+x^2}]\)

Let's do each side individually.

Left Side:

We have:

\(\frac{d}{dx}[\tan(x-y)]\)

We can use the chain rule, where:

\((u(v(x))'=u'(v(x))\cdot v'(x)\)

Let u(x) be tan(x). Then v(x) is (x-y). Remember that d/dx(tan(x)) is sec²(x). So:

\(=\sec^2(x-y)\cdot (\frac{d}{dx}[x-y])\)

Differentiate x like normally. Implicitly differentiate for y. This yields:

\(=\sec^2(x-y)(1-y')\)

Distribute:

\(=\sec^2(x-y)-y'\sec^2(x-y)\)

And that is our left side.

Right Side:

We have:

\(\frac{d}{dx}[\frac{y}{8+x^2}]\)

We can use the quotient rule, where:

\(\frac{d}{dx}[f/g]=\frac{f'g-fg'}{g^2}\)

f is y. g is (8+x²). So:

\(=\frac{\frac{d}{dx}[y](8+x^2)-(y)\frac{d}{dx}(8+x^2)}{(8+x^2)^2}\)

Differentiate:

\(=\frac{y'(8+x^2)-2xy}{(8+x^2)^2}\)

And that is our right side.

So, our entire equation is:

\(\sec^2(x-y)-y'\sec^2(x-y)=\frac{y'(8+x^2)-2xy}{(8+x^2)^2}\)

To find dy/dx, we have to solve for y'. Let's multiply both sides by the denominator on the right. So:

\(((8+x^2)^2)\sec^2(x-y)-y'\sec^2(x-y)=\frac{y'(8+x^2)-2xy}{(8+x^2)^2}((8+x^2)^2)\)

The right side cancels. Let's distribute the left:

\(\sec^2(x-y)(8+x^2)^2-y'\sec^2(x-y)(8+x^2)^2=y'(8+x^2)-2xy\)

Now, let's move all the y'-terms to one side. Add our second term from our left equation to the right. So:

\(\sec^2(x-y)(8+x^2)^2=y'(8+x^2)-2xy+y'\sec^2(x-y)(8+x^2)^2\)

Move -2xy to the left. So:

\(\sec^2(x-y)(8+x^2)^2+2xy=y'(8+x^2)+y'\sec^2(x-y)(8+x^2)^2\)

Factor out a y' from the right:

\(\sec^2(x-y)(8+x^2)^2+2xy=y'((8+x^2)+\sec^2(x-y)(8+x^2)^2)\)

Divide. Therefore, dy/dx is:

\(\frac{dy}{dx}=y'=\frac{\sec^2(x-y)(8+x^2)^2+2xy}{(8+x^2)+\sec^2(x-y)(8+x^2)^2}\)

We can factor out a (8+x²) from the denominator. So:

\(\frac{dy}{dx}=y'=\frac{\sec^2(x-y)(8+x^2)^2+2xy}{(8+x^2)(1+\sec^2(x-y)(8+x^2))}\)

And we're done!

Answer:

ML=93

Step-by-step explanation: x+243 is the total length of the line. So you want to put x+243 on one side of the equation and everything else on the other side.

x+243=110+4x+x+103+70 combine like terms

x+243=283 +5x subtract 5x from both sides

-4x+243=283 subtract 243 from both sides to get x by its self

-4x=40 Divide both sides by -4

x= -10

Now fill in -10 anywhere there is an x to check

-10+243=110+(4* -10)+ -10+103+70 Simplify

233=110+ -40+ 163

233=233

Since it is correct you now know that ML= -10+103

Answer:

2.5 is the answer

Step-by-step explanation:

The expression that fails to compute the area of a triangle correctly is option b: (1 / 2) * b * h.

The correct formula to compute the area of a triangle is one-half times the base multiplied by the height, which can be written as (1/2) * b * h. Option a, c, and d correctly represent this formula. However, option b is incorrect because it uses integer division instead of decimal division.

In option b, (1 / 2) is computed using integer division, which results in truncating the decimal part. Therefore, (1 / 2) evaluates to 0 instead of 0.5. As a result, the expression (1 / 2) * b * h would yield incorrect and significantly smaller results than the actual area of the triangle.

To accurately calculate the area of a triangle using this formula, it is essential to use decimal division or explicitly represent the fraction as a decimal. Options a, c, and d correctly account for this by using either 1.0/2.0 or 0.5, ensuring the proper calculation of the area.

To evaluate the expression, substitute the given value for the variable. In this case, given that x = 2. Then substitute this value into the expression and simplify.

f(x) = (-2x + 3 if x < -2)

To graph the solution set to the system of inequalities y > x^2 - 1 and y ≤ -x^2 + 4, shade the region between the two graphs, above the graph of f(x), and below the graph of g(x).

To graph the solution set to the system of inequalities y > x^2 - 1 and y ≤ -x^2 + 4, we need to shade the region on the coordinate plane that satisfies both inequalities.

To do this, we first graph the functions f(x) = x^2 - 1 and g(x) = -x^2 + 4 on the same coordinate plane. We can do this by plotting points or by using a graphing calculator or software.

Next, we shade the region above the graph of f(x) and below the graph of g(x). This is because the inequality y > x^2 - 1 means that y is greater than the values of f(x), which are the points above the graph of f(x). The inequality y ≤ -x^2 + 4 means that y is less than or equal to the values of g(x), which are the points below the graph of g(x).

The solution set is the region on the coordinate plane that is shaded in both ways. This region is the area between the two graphs, above the graph of f(x), and below the graph of g(x). We can identify the solution set by looking at the shaded region on the graph or by listing the coordinates of the points that satisfy both inequalities.

\(3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}\)

The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.

Note that the two numbers given the equation |n-3| = 5 which are 5 units from 3 on the number line are: -2 and 8.

A number line is a picture of a graduated straight line that serves as a visual representation of real numbers in elementary mathematics. Every number line point is assumed to correspond to a real number and every real number to a number line point.

One more quality of number lines that is worth noting is that it stretched to the positive infinity and to the negative infinity with zero as the center point.

Given that we have been given the reference point of 3, this means that both numbers must extend one to the positive infinity constrainted by 5 units and one to the negative infinity constrained by 5 units.

Hence,

To find the two numbers that are 5 units away from 3, we can set up two equations:

n - 3 = 5 and n - 3 = -5

Solving for n in the first equation: n = 8

Solving for n in the second equation: n = -2

Therefore, the two numbers that are 5 units away from 3 on the number line are -2 and 8.
