14a -ac = 8w - 6w
a(14-c) = 2w
a= 2w / 14 - c
Fed [463]3 years ago
5 0

Answer:

a = 2w/c/15

Step-by-step explanation:

14a = ac + 2w

ac + 2w + 14a = 0

ac + 14a = -2w

14a + a = -2w/c

15a = 2w/c

a = 2w/c/15

Find sec(2Arcsin (-1/3))
gavmur [86]
<span>Think of arcsin (-1/3) as an angle, and call it "theta."  The the original problem becomes "find sec [ 2 theta ]"
                                                       1                                    1
which is the same as     "find ------------------ " or --------------------------------------
                                                cos[2 theta]          (cos theta)^2 - (sin theta)^2

Recall that theta = the angle whose sine is -1/3.  Thus, sin theta = -1/3 and cos theta = 2sqrt(2) / 3.

So we now have: 

                   1
-------------------------------------------
   2 sqrt(2)                     -1
[------------------- ]^ 2 - [ ------- ]^2
           3                           3

which boils down to:

          1                   1
----------------- = ---------------- = 9/7 (answer)
   8         1               7/9
------ - --------
   9          9

Find the area of the figure. Round to the nearest hundredth when necessary
dexar [7]

Answer:

  745.44 square mm

Step-by-step explanation:

The figure can be decomposed into ...

  • a semicircle of radius 12.5 mm
  • a rectangle 12.5 mm by 25 mm
  • a triangle 12.5 mm by 30 mm

The relevant area formulas are ...

  Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²

  Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²

  Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²

Total area of the figure is ...

  245.437 +312.500 +187.500 = 745.437 . . . mm²

The area of the figure is about 745.44 square mm.
