Answer:

4 + 2i

Step-by-step explanation:

Since

$\sqrt{ - 1} = i$

$4 + \sqrt{ - 4} = 4 + \sqrt{ - 1 \times {2}^{2} } \\ = 4 + 2i$

Suppose that 40 deer are introduced in a protected wilderness area. The population of the herd

Scorpion4ik [409]

The horizontal asymptote of the function is the minimum number of deer in the area.

The equation of horizontal asymptote is: $\mathbf{y = 40}$
The horizontal asymptote means that, the number of deer will never be less than 40

The equation is given as:

$\mathbf{f(x) = \frac{40 + 2x}{1 + 0.05x}}$

Expand the numerator

$\mathbf{f(x) = \frac{40(1 + 0.05x)}{1 + 0.05x}}$

Cancel out the common factor

$\mathbf{f(x) = 40}$

Hence, the equation of horizontal asymptote is:

$\mathbf{y = 40}$

The horizontal asymptote means that, the number of deer will never be less than 40

Given the polynomial 2x3 + 18x2 − 18x − 162, what is the value of the coefficient 'k' in the factored form?2x3 + 18x2 − 18x − 16

s344n2d4d5 [400]

Answer:

$k=3$

Step-by-step explanation:

Let

$f(x)=2x^3+18x^2-18x-162$

We factor 2 to obtain;

$f(x)=2(x^3+9x^2-9x-81)$

We factor the polynomial within the parenthesis by grouping.

$f(x)=2(x^2(x+9)-9(x+9)$

$f(x)=2(x^2-9)(x+9)$

$f(x)=2(x^2-3^2)(x+9)$

We apply difference of two squares on the second factor: $x^2-3^2=(x-3)(x+3)$

$f(x)=2(x+3)(x-3)(x+9)$

We now compare to;

$f(x)=2(x+k)(x-k)(x+9)$

It is now obvious that $k=3$

Simplify (2^5/3^2)^4 I need help asap within 10 min

Daniel [21]

Answer:

$\frac{2^{20} }{3^{8} }$

Step-by-step explanation:

Exponent Multiplication Rule :

$(\frac{x^{a} }{y^{b} } )^{c} = \frac{x^{ac} }{y^{bc} }$

=============================================================

Solving :

⇒ $(\frac{2^{5} }{3^{2} } )^{4}$

⇒ $\frac{2^{5(4)} }{3^{2(4)} }$

⇒ $\frac{2^{20} }{3^{8} }$
