8th payment, if you want how to get the answer I made a chart as shown in the picture
Answer:
18
Step-by-step explanation:
Divide with by paratheses first. Use PEMDAS method
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....
3.1
First, we need to convert 10/100s into a decimal. We can simplify it to 1/10, which is also 0.1.
Then, we add 0.1 to 3 and get our answer: 3.1.
Hope this helped!
