3060÷180 +2

using the formula (n-2) × 180 = sums of interior angles

Sum of interior angles=(n-2)180
3060=(n-2)180
3060/180=n-2
17=n-2
n=17+2
n=19..

Find the linear approximation of f(x)=lnx at x=1 and use it to estimate ln(1.38).

RideAnS [48]

$\bf f(x)=y=ln(x)\qquad 
\begin{cases}
x=1\\
y=ln(1)\to y=0
\end{cases}\\\\
-----------------------------\\\\
\left. \cfrac{dy}{dx}=\cfrac{1}{x} \right|_{x=1}\implies 1\impliedby m
\\\\\\
\textit{now, we know that }
\begin{cases}
x=1\\
y=0\\
m=1
\end{cases}\implies y-0=1(x-1)\implies y=x-1$

now, you're asked to use it when ln(1.38), which is just another way of saying x = 1.38

so set x = 1.38 and see what "y" is

This should be easy to answer with a calculator but I don’t really have a calculator on hand lol so please solve it for me:

GuDViN [60]

Answer:

- 132

Step-by-step explanation:

This can be evaluated without a calculator.

Take each part of the calculation and evaluate, that is

- 6(3)(- 4) = - 6 × - 12 = 72

3(3)²(- 4) = 3 × 9 × - 4 = - 12 × 9 = - 108

2(3)(- 4)² = 6 × 16 = 96

Putting the 3 parts back together

72 - 108 - 96

= 72 - 204

= - 132
