Answer:
b). 16.
Step-by-step explanation:
x^2 = 4
We can write this as
x^2 + 0x - 4 = 0
The discriminant (b^2 - 4ac) =
0^2 - 4 * 1* -4
= 16.
Answer: Not sure if it needs to be rounded but if it doesn't then its x=3.7876 but if it needs to be rounded to the nearest tenth then its x=3.8
Step-by-step explanation:
Answer:
20.9 ft
This is a right triangle trigonometry question because N is 90 degrees. MN is adjacent to M and LM is the hypotenuse. Adjacent any hypotenuse use the cosine function.
plug in known values
switch cos(20) and x using the products property
plug into calculator to get 20.9 ft
