Answer:
For k = 6 or k = -6, the equation will have exactly one solution.
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
If , the equation has only one solution.
In this problem, we have that:
So
We will only have one solution if . So
For k = 6 or k = -6, the equation will have exactly one solution.
Answer:
27% = 0.27 of 146.000 = 39.420
Add 39.420 at current value (39420+14600 ) = 185.420
Answer:
t to the sixth power equals 9
t=1.5
Step-by-step explanation:
Use the Pythagoras' Theorem:
A^2 + B^2 = C^2
20^2 + 35^2 = C^2
400+ 1225=1625=C^2
square root of 1625= C = 40.31 km
