A "hole" is created when a factor can be crossed out of the numerator and denominator.
x^2 - x - 2 factors into (x - 2)(x + 1) both of which can be crossed out or canceled with the factors in the numerator. That creates very really tiny holes at x = 2 and x = - 1.
Answer:
19 691 miles
Step-by-step explanation:
Last year, it drove 100%, which is 196,910. This year, it drove 90% lesser, so it actually only drove: 100% - 90% = 10%.
10% as a fraction is 
.
Distance travelled this year = × 196 910
= 19 691 miles
The answer to this question is 120 hope this helps
Answer: 60%
Step-by-step explanation: 24/40 = .6 x 100 = 60
Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m
