The fish population in a local stream is decreasing at a rate of 4% per year. The original population was 55,000 fish. What is t
Svet_ta [14]

Answer: 38090 fish

Step-by-step explanation:

Use the equation 55,000(.96)^9. Start with the initial number in this case it is 55,000 then multiply by the percentage that remains (100% - 4% = 96%) and then put it to the ninth power because that is how many years the problem is asking for.

the boundary of a rectangular farm field in ireland has a straight rock wall along one side and fences along its other three sid
Inessa [10]

Answer:

781250 ft^{2}

Step-by-step explanation:

Let y is the length of the farm field

Let x is the width of the farm field

Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:

2x + y = 2500 feet

<=> y = 2500 -2x

The are of the farm has the following formula:

A = x*y

<=> A = x(2500 - 2x)

<=> A = 2500x -2x^{2}

To have  the maximum area of field in square feet, we need to use differentials to estimate:

\frac{dA}{dx} = 2500 - 4x

Set \frac{dA}{dx} = 0, we have:

2500 - 4x  = 0

<=> x = 625 feet.

=> y = 2500 - 2*625 = 1250 feet

So the maximum area of field is:

A = x*y = 625*1250 = 781250 ft^{2}

Find the remainder when x4 - 5x3 + x2 - 10x - 5 is divided by x + 3.
m_a_m_a [10]

Use the remainder theorem: we can decompose the given polynomial in terms of quotient and remainder polynomials q(x) and r(x), respectively, such that

x^4 - 5x^3 + x^2 - 10x - 5 = (x + 3) q(x) + r(x)

Then letting x = -3 makes the quotient term vanish, and we're left with a remainder of

r(-3) = (-3)^4 - 5\times(-3)^4 + (-3)^2 - 10\times(-3) - 5 = \boxed{250}
