Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

= 6x²+6x+3x+3+3x²-2x+8

= 9x²+7x+11

Difference:

(50x²-9x²)+(-34x+7x)+(38-11)

= 41x² - 27x + 27

An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole f
maria [59]

Answer:

X=49ft

Step-by-step explanation:

From the question we are told that:

Height of Eagle h=40ft

Angle of depression \theta=35\textdegree

 

Generally the trigonometry equation for diagonal X is mathematically given by

Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }

Cos\theta \textdegree=\frac{h}{X} }

X=\frac{40}{Cos 35 } }

X=48.83ft

X=49ft

Assume that the cost to produce an item is a linear function and all items produced are sold. A lumber yard has fixed costs of $
V125BC [204]

Answer:

2028 ft

Step-by-step explanation:

Let the feets of boards sold to get profit be x hence with the price of $1.13 which is inclusive of profit, the total sales will be 1.13 x

The cost per day will equally be the sum of variable cost which considers the feets of boards and the daily fixed charge. Considering the variable of $0.03 and fixed charge of $2230.80 then the equation is represented as 0.03x+2230.80

Relating the two equations then

1.13x=0.03x+2230.80 and rearranging like terms

1.13x-0.03x=2230.80

1.1x=2230.8

X=2230.8/1.1=2,028 ft

Therefore, to maximize daily profit, 2028 ft must be sold
