Answer:

D. 507 square units

Step-by-step explanation:

surface area of the rectangular pyramid

$= area \: of \: base + 4 \times area \: of \: one \: \triangle \\ \\ = {13}^{2} + 4 \times \frac{1}{2} \times 13 \times 13 \\ \\ = 169 + 2 \times 169 \\ \\ = 169 + 338 \\ \\ = 507 \: {units}^{2} \\$

Answer:

$\displaystyle y=5+\frac{x}{10}$

$\displaystyle y=10+\frac{(x-75)}{20}$

Step-by-step explanation:

Linearization

It consists of finding an approximately linear function that behaves as close as possible to the original function near a specific point.

Let y=f(x) a real function and (a,f(a)) the point near which we want to find a linear approximation of f. If f'(x) exists in x=a, then the equation for the linearization of f is

$y=f(x)=f(a)+f'(a)(x-a)$
