Answer:

Step-by-step explanation:

W=2L-2

A=72

LW=72

L(2L-2) = 72

2L^2 -2L= 72

2L^2 -2L-72=0

L^2 - L -36 = 0

L= -5.52 or 6.52(neg # not a solution)

W=11.04

L=6.52

DIAG = \sqrt{11.04^2+6.52^2} = 12.82

Find the domain of the graphed function?
MariettaO [177]

<span>Remember, the domain of a function is all of the x values in the (x,y) coordinates. For this, let’s take a few bench mark coordinates. (0,0) (1,2.5)(2,0) (3, -9). Those definitely aren’t all real numbers, so eliminate A. X is not only less than or equal to 0, so eliminate C. </span>

Solve for x.<br> 8(5 + x) = 11(9 + x)<br> Answer as a fraction.
7nadin3 [17]

distribute the 8 to the 5 and x. then distribute 11 to 9 and x.

(40+8x)=(99+11x)

-11x -11x

-3x+40=99

-40 -40

-3x= 59

divide three on both sides

x=59/-3

final answer x=-59/3

HELP ME SOLVE THIS ASAP
vampirchik [111]

Answer:

∠B = 60°

a = 4.0 units

b = 6.9 units

Step-by-step explanation:

The triangle is right angled. The sum of all angles of a triangle is equal to 180 degrees.

The 3 angles are 90, 30 , ∠B .

<em>90+30+B = 180</em>

Thus, B = 180 - 120 = 60 degrees

by trigonometry,

sin(30) = \frac{a}{8} = 0.5

a = (8)(0.5) = 4 units

Also,

cos(30) = \frac{b}{8} = 0.866

b = (8)(0.866)= 6.928
