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....
Answer:
The answer is 7
Step-by-step explanation:
5x7=35
Answer:
The Product is negative three (-3)
WHILE
The number is negative one (-1)
Step-by-step explanation:
Since seven more than the product gives 4.
This means 7 + product = 4
By subtracting 7 from both sides we get product as -3.
And since the product of the number and 3 is equal the product
This means number X 3 = -3
By dividing three from both sides you get -1.
