Answer:

\frac{11}{2}

Step-by-step explanation:

\frac{x}{AB}=cos60

x=\frac{AB}{2}=\frac{11}{2}

in a right angled triangle cosA=\frac{adjacent}{hypotenuse}

so cosB=\frac{x}{11}

\frac{1}{2}=\frac{x}{11}

x=\frac{11}{2}

Answer:

  • 5.5 units

Step-by-step explanation:

x is the smallest side because it is opposite of 30° angle.

<u>The side opposite to 30° is half the hypotenuse:</u>

  • BC = AB/2
  • x = 11/2
  • x = 5.5

A carpenter is building a bookcase of height h, length 2h, and width w. The bookcase has two shelves. The plywood to be used for
tresset_1 [31]

Answer:

3h² + 35hw ;

a = 3 ; b = 2 ; c = 35

Step-by-step explanation:

Given that :

Dimension of bookcase :

Height = h ; Length = 2h ; width = w

Area of backside :

Height * length

h * 2h = 2h²

Cos of back material = $1.5 per ft²

Cost = 1.5 * 2h²

Cost = 3h²

Top and bottom :

Length * width

2h * w

Side area = 3 * h * w

Total area : Top + bottom +. Side

Total area : 2hw + 2hw + 3hw = 7hw

Pine = $5 per sq foot

Total cost = $5 * 7hw

= $35hw

Entire cost, C

3h² + 35hw

From the format :

ah^b + chw,

a = 3 ; b = 2 ; c = 35

PLEASE HELP!
____ [38]
<h3>Answer:</h3>
  • A. x = -2
  • B. (-2, -3), (-3, -1)
  • C. x = 0
<h3>Step-by-step explanation:</h3>

Part A. The solution is represented by the point at which the graphs intersect: (-2, -3). The x-value that makes p(x) = f(x) is x = -2.

___

Part B. The point found in Part A is one solution to f(x). The graph shows the line has a slope of -2, so another point will be 1 to the left and 2 up: (-3, -1). So, two solutions are ...

... (-2, -3) and (-3, -1)

___

Part C. The graphs of p(x) and g(x) intersect at the point (0, 2). This means

... p(0) = g(0) = 2

So, x = 0 is the solution to the equation p(x) = g(x).
