Answer:

A) y=3x+1

Step-by-step explanation:

Use the formula y=mx+b

m is the slope and b is the y intercept

the graph starts on 1 on the y axis so you replace 1 for b

the slope goes up 3 and over one, giving the fraction 3/1 or just 3. so you replace 3 for m.

Please help me find the area for this hexagon (please show work to) ,:)

kvasek [131]

Check the picture below.

so the area of the hexagon is really just the area of two isosceles trapezoids.

$\textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h=height\\ a,b=\stackrel{parallel~sides}{bases}\\[-0.5em] \hrulefill\\ a=2\\ b=4\\ h=2 \end{cases}\implies \begin{array}{llll} A=\cfrac{2(2+4)}{2}\implies A=6 \\\\\\ \stackrel{\textit{twice that much}}{2A = 12} \end{array}$

Find the area of the region enclosed by f(x) and the x-axis for the given function over the specified interval.

Nat2105 [25]

Answer:

Step-by-step explanation:

Complete Question

The complete question is shown on the first uploaded image

Answer:

The area is $A =8 sq\cdot unit$

Step-by-step explanation:

From the question we are told that

The first equation is $f(x) = x^2 + x \ \ \ x< 1$

$on[ -2 , 3 ]$

The second equation is $f(x) = 2 x \ \ \ x \ge 1$

This means that the limit of the area under the enclosed region is limited between -2 to 1 on the x- axis for first equation and 1 to 3 for second equation

Now the area under the region is evaluated as

$A = \int\limits^1_{-2}{x^2 + x } \, dx + \int\limits^3_{1}{2x } \, dx$

$A ={ \frac{x^3}{3} + \frac{x^2}{2} + c } | \left \ 1 } \atop {-2}} \right. + {\frac{2x^2}{2} }| \left \ 3} \atop {1}} \right.$

$A =9 + c - 1 -c$

$A =8 sq\cdot unit$
