This is a right triangle. We know that

                                                 \tan x = \frac{\text{opposite side}}{\text{adjacent side}}

Therefore,

                                              \tan x = \frac{18}{21} = \frac{6}{7} = 0.857

Now we have:

                                                 x=\tan^{-1}0.86

                                                       x=40.6

Is the system of equations consistent, consistent and coincident, or inconsistent? y=3x+4y=3x+3 Select the correct answer from t
Genrish500 [490]

Answer: Inconsistent

<u>Step-by-step explanation:</u>

y = 3x + 4   → m = 3, b = 4

y = 3x + 3   → m = 3, b = 3

These equations have the same slope but different y-intercepts so they are parallel lines <em>which means they will never intersect.</em>

NOTES

  • one solution: consistent & independent        <em>lines cross</em>
  • infinite solutions: consistent & dependent     <em>same line</em>
  • no solution: inconsistent                                  <em>parallel lines</em>

Simplified form of m^7(m^2)m^-9
Mice21 [21]
I think it’s m^5 because if you multiply m^7 times m^2 you get m^14 and if you combine it with m^9 you subtract 9 and get m^5

oksian1 [2.3K]

Answer:

201ft

Step-by-step explanation:

The circumference of a circle is equal to

C=piD

d=64ft

substitute:

c=pi(64)=64pift ft

assume pi=3.14

64pi=64*3.14=200.96ft

round to the nearest whole number:

200.96=201ft

another explanation:

Answer:

Length of the fencing required = 201.06 meters

Step-by-step explanation:

Architect is planning a circular playground with diameter = 64 m

We have to calculate the fencing required to cover this playground.

Length of fencing = circumference of the playground

Since circumference of a circle = π × (Diameter)

                                                   = 64π

                                                   = 201.06 meters

Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
