Answer:
The approximate distance is 15416 miles....
Step-by-step explanation:
We have given:
A satellite is 19,000 miles from the horizon of earth.
The radius is 4,000 miles.
Lets say that BC =x
AO = OB = 4,000 miles
AC = 19,000 miles
The tangent from the external point forms right angle with the radius of the circle.
So in ΔABC
(OC)² = (AC)²+(OA)²
where OC = x+4000
AC = 19,000
OA = 4000
Therefore,
(x+4000)² = (19,000)² +(4,000)²
Take square root at both sides:
√(x+4000)² = √(19,000)² +(4,000)²
x+4000 =√361000000+16000000
x+4000 = √377000000
x+4000 = 19416.48
x= 19416.48 - 4000
x = 15416.48
Therefore the approximate distance is 15416 miles....
It should be -16, assuming you are asking for -4*4. If you meant -4^4 (-4 to the fourth power) then the answer is 256.
To do this first we will take the fraction and turn it into decimal form. To do this we will divide the numerator and the denominator.
7 ÷ 16 = <span>0.4375
Now to take it to percent form we will multiply by 100.
0.4375 </span>× 100 = 43.75%
So, 7/16 turned into a percentage would be 43.75%
Hope I helped ya!!
1. If you knew that DE =
CB
Then you would know it is a mid-segment.
2. If you knew that CD = DA and BE = EA (point D and point E are midpoints of their respective segments)
