The answer to this is 2.
There are a number of proofs to this. Here, we use Euclidean geometry with trigonometry. If we let the center of the circle to be O.
Then, we have the following equations for the angles
CEO = OED = 90
Since, CO = OD because they're radii of the circle, then
ΔCOD is an isosceles triangle and
OCE = ODE
CE + DE = CD
dividing the whole equation by DE
CE/DE + 1 = CD/DE
Using trigonometric functions:
CE = OC cos OCE and
DE = OD cos ODE
Substituting.
OC cos OCE / OD cos ODE + 1 = CD/DE
Since, OCE = ODE,
cos OCE = cos ODE
The equation would be reduced to:
1 + 1 = CD/DE
CD/DE =2

Answer: Change 4.62 to 462.
Step-by-step explanation: If you multiply 4.62 by 100 you get 462.
1) 46/6 = 7 r 4
2) Drop down the 2 and 42/6 equals 7.
3) This will make each person get 77.
Answer: 77

<span>The ordered pair is (5000,12). This is given from the function a at x=5000, which is written in the question as a(5000)=12. Here, a is our dependent variable and is equal to 12. The x value, or independent variable is given as 5000. Ordered pairs are written (x,y) or (independent, dependent), thus the ordered pair is (5000,12).</span>
