why isn't there a sig n between the 3(x+5)2-4
Y = -12 , -9
That’s the answer and good luck!
Answer:
The distance of Satelite from the earth's surface = 2720.12 miles
Step-by-step explanation:
Below is the calculation for distance:
Use Pythagorean theorem
Distance, d² = 5400² + 4000²
d² = 45160000
d = 6720.12
Subtract the radius to find the distance from earth's surface.
Distance = 6720.12 - 4000 = 2720.12
The distance of Satelite from the earth's surface = 2720.12 miles
The soulation is given by s=3 because it makes the value of 3s+12 equal to 21
