Find an nth-degree polynomial function with real coefficients satisfying the given conditions. If you are using a graphing utili

Marrrta [24]

We need to find a polynomial function f(x) with degree 3 and zeros 2 and 2i, such that:

$f(-1)=30$

Since 2i is a zero, -2i is also a zero of this function. Thus, we have:

$f(x)=a(x-2)(x-2\imaginaryI)(x+2\imaginaryI)$

where a is a constant.

Expanding the expression on the right side, we obtain:

$\begin{gathered} \\ f(x)=a(x-2)\lbrack x²-(2i)²\rbrack \\ \\ f(x)=a(x-2)(x²-4i²),\text{ i^^b2=-1} \\ \\ f(x)=a(x-2)(x²+4) \\ \\ f(x)=a(x³-2x²+4x-8) \end{gathered}$

Now, using f(-1) = 30, we obtain:

$\begin{gathered} 30=a\lbrack(-1)³-2(-1)²+4(-1)-8\rbrack \\ \\ 30=a(-1-2-4-8) \\ \\ 30=a(-15) \\ \\ a=\frac{30}{-15} \\ \\ a=-2 \end{gathered}$

Therefore, the function is:

Find the surface area of the pyramid. the surface area of the pyramid is __in squared.

iVinArrow [24]

Answer:

$561.08in^{2}$

Step-by-step explanation:

$S A = lw + l$ $\sqrt{(\frac{w}{2})^{2} + h^{2} } + w$ $\sqrt{(\frac{l}{2})^{2} + h^{2} }$

$SA = 14(14) + 14 \sqrt{(\frac{14}{2})^{2} + 11^{2} }+ 14 \sqrt{(\frac{14}{2})^{2} + 11^{2} } = 561.08in^{2}$
