The rate of change in the function y=x+4 is________ the rate of change of the function represented in the table.

Snezhnost [94]

Recall that the slope is the "average rate of change" of any function.

$\bf y=\stackrel{slope}{1}x+4\qquad \qquad 
\begin{array}{ccll}
x&y\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
0&6\\2&8\\4&10\\6&12
\end{array}
\\\\\\
\textit{let's check what is the slope of the tabled function}\\
\textit{by using two points from it}$

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 2}}\quad ,&{{ 8}})\quad 
% (c,d)
&({{ 6}}\quad ,&{{ 12}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{12-8}{6-2}\implies \cfrac{4}{4}\implies 1$

When a farmer is standing 80 feet from a silo, he must look up

Alisiya [41]

Answer:

102.40 ft

Step-by-step explanation:

This system can be described as a right triangle with the horizontal distance from the silo (80 ft) being the side adjacent to the 52-degree angle, and the height of the silo (h) being the side opposite to the angle. Therefore, the height can be found by:

$tan(52) = \frac{h}{80}\\ h=102.40\ ft$

The silo is 102.40 feet tall.
