Step-by-step explanation:
![5\ is\ a \ root \of \ x^2+(k-1)*x-5=0\\\\5^2+(k-1)*5-5=0\\\\5*(k-1)+20=0\\\\k-1=\dfrac{-20}{5} \\\\k=-4+1\\\\\boxed{k=-3}\\](https://tex.z-dn.net/?f=5%5C%20is%5C%20a%20%5C%20root%20%5Cof%20%5C%20x%5E2%2B%28k-1%29%2Ax-5%3D0%5C%5C%5C%5C5%5E2%2B%28k-1%29%2A5-5%3D0%5C%5C%5C%5C5%2A%28k-1%29%2B20%3D0%5C%5C%5C%5Ck-1%3D%5Cdfrac%7B-20%7D%7B5%7D%20%5C%5C%5C%5Ck%3D-4%2B1%5C%5C%5C%5C%5Cboxed%7Bk%3D-3%7D%5C%5C)
h+1 is thus a root of x²+(-3-1)*x-5=0
x²-4x-5=0
x²+x-5x-5=0
x(x+1)-5(x+1)=0
(x+1)(x-5)=0
h+1=-1
<u>h=-2</u>
Answer:
C. 1.12
Step-by-step explanation:
There are 60' (minutes) in a degree and 60" in a minute meaning that we have (60×60) seconds in a degree.
Therefore to convert seconds to degrees we divide by 3600. and minutes to degrees we divide by 60.
The angle 48°19'23'' can be converted into a decimal as follows
48°+(19/60+23/3600)°
=48.323°
Tan 48.323= 1.12
