Hello, I need this question for today but I dont get it.. Can someone please help me?​
Bas_tet [7]

Answer:

<em>A = 32²cm</em>

Hope this helped!

Step-by-step explanation:

<h3>A = lw/2</h3>

<u>We know that the width is 8cm, and that the length of the rectangle and triangle combined is 14cm.</u>

<u />

How we find the length of the triangle itself is 14cm - 6cm, since 6cm is the rectangles length (which we know because it gives it to us at the top!)

14cm - 6cm = 8cm

<h3>Now we can plug into our formula and solve</h3>

A = 8(8)/2

A = 64/2

<h3><em>A = 32²cm</em></h3>

HELP ME PLEASE. . Donna's company reimburses her expenses on food, lodging, and conveyance during business trips. The company pa
BlackZzzverrR [31]
Well, she drove 200 miles, at a pay of $0.60 per mile travelled. 
<span>200 * 0.6 = 120 </span>
<span>She got payed $120 for her 200 miles traveled. </span>

<span>Since she gets payed $50 per day, and she got paid $1500 for her food and lodging, she traveled for 30 days as 1500/50 = 30 (Part C answer) </span>

<span>If you were to determine her total pay: </span>
<span>Using variables x for: number of days spent on trip </span>
<span>Y: number of miles traveled. </span>

<span>Total pay = 50x + 0.6y </span>
<span>If you'd rather have only the equation for the number of days spent on her trip: </span>
<span>X = (1620- 0.6(200))/50. (Part A answer) </span>

<span>Solving for x: </span>

<span>X = (1620 - 0.6(200))/50 </span>
<span>X = (1620 - 120)/50 </span>
<span>X = (1500)/50 </span>
<span>X = 30 (Part B answer)</span>

Let f(x)=x2−12x. To prove that limx→6f(x)=−36, we proceed as follows. Given any ϵ&gt;0, we need to find a number δ&gt;0 such tha
katovenus [111]

Answer:

Take \delta = \sqrt{\epsilon}

Step-by-step explanation:

To begin notice that

\big| x^2 -12x-(-36) \big| = \big| x^2 -12x+36 \big| = \big| (x-6)^2 \big|\\= \big|x-6\big|*\big|x-6 \big| \leq \delta*\delta = \delta^2

If we chose the following delta

\delta = \sqrt{\epsilon}

that solves our problem !
