Note that

\frac{x^2-1}{x^3 - 2x^2 -x+2}=\frac{x^2 -1}{x^2 (x-2)-(x-2)}=\frac{x^2 -1}{(x^2 -1)(x-2)}

So, for all x \neq \pm 1, f(x)=\frac{1}{x-2}.

So, the graph looks like something like as following in the image.

Maria leaves her house and walks north for 6 blocks. She then turns and walks directly east for 8 more blocks
Shtirlitz [24]

Answer:

36+64=100 100 to the square root is 10

Step-by-step explanation:

I'm not giving a diagram just draw a triangle and make the base of it 8 and the length of it 6 but the diagonal part 10

It's the pythagorean theorum. a^2 + b^2 = c^2

^2= to the 2nd power. or squared.

In this case it really doesnt matter which one you label for this part of math.

so 8^2 + 6^2 = C^2 where C is the shortest distance between the houses.

and 8 and 6 were the lengths given.

64+36=100

100's square root is 10 because 10^2 is 100 or 10*10 is 100. If you dont know what squaring is.

Its multiplying something by that something once so 1 squared is 1 because its 1*1 you are multiplying it once 2 squared or 2^2 is 4 because 2*2 is 4 3 squared or 3^2 is 9 because 3*3 is 9. 4 squared is 16 because 4*4 is 16. and if you did 2 to the power of 3 of 2 cubed it would be 8 because 2*2*2 is 8.

soldier1979 [14.2K]

Answer:

(a) 1/2

(b) 9/10

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

(a) Number of possible outcomes = 5 questions, number of total outcomes = 10 questions

Probability (I answer all 5 problems correctly) = 5/10 = 1/2

(b) Probability (I answer at least 4 of the problems correctly) means I either answer 4 of the problems or all 5 problems correctly = 4/10 + 5/10 = 9/10
