Sin = - 4/8

Quadrant IV = only cosine is positive

a = height (4)
b = base ( 8^2-4^2=b^2
b = 6.93 @
\sqrt{48}

c = hypothenuse(8)

cos =
\sqrt{48}
/8

tan = - 4/
\sqrt{48}

sec = 1/cos
1/cos = 1/ (
\sqrt{48}
/8)
sec = 8/
\sqrt{48}

csc = 1/sin
1/sin = 1/(-4/8)
csc = - 2

cot = 1/tan
1/tan = 1/(-4/
\sqrt{48}
)
cot = -
\sqrt{48}
/4

Nostrana [21]

Point slope from would be 12x-y+26=0.

Black is the equation, 12x-y+26=0.

  • Orange is <em>y-14=12(x+1)</em>
  • Blue is <em>y-14=12(x-1)</em>
  • Red is <em>y+14=12(x-1)</em>
  • Green is <em>y-14=-12(x+1)</em>

The length of the triangle for the pool table is the twice the sum of 5 and a number. If the rack is
gayaneshka [121]

Answer:

30 + 6x inches

Step-by-step explanation:

Let the required number be x

If the length of the triangle for the pool table is the twice the sum of 5 and a number

L = 2(5+x)

L = 10+2x

Since the triangle is quadilateral, this means that all sides are equal

Perimeter = 3L

Perimeter = 3(10+2x)

Perimeter = 30+6x

Hence the perimeter, in inches, of the triangle is 30 + 6x inches

Solve (get the variable by itself): m / (-4) = -2.95
kenny6666 [7]
M / -4 = -2.95
As you can see, the variable m is currently in a fraction with a denominator of -4. So to get ride of the fraction and find m and its value, you should multiply both sides by the denominator of the fraction, which is in our case -4.
So m / -4 = -2.95
(m/-4) * -4 = -2.95 * -4
m = 11.8

You can recheck your answer (very important):
m / -4 = 11.8 / -4 = -2.95
The answer has been approved.

Hope this Helps! :)
