Answer:
x = 12
Step-by-step explanation:
Recall: the secant-tangent rule states that when a secant and a tangent meet at an external point of a circle, the product of the secant and the external segment is equal to the square of the tangent segment
(x)(3) = 6² (secant-tangent rule)
3x = 36
Divide both sides by 3
3x/3 = 36/3
x = 12
The point would be on the -2.
X=-2
Move variable to the left and than you divide both sides of equation by 4
Answer:
2.55°C
Step-by-step explanation:
Calculate the temperature at the 2 given depths
x = 1200
T =
= 3.75
x = 3750
T =
= 1.2
Difference in temperature = 3.75 - 1.2 = 2.55°C
