Are you sure you have your numbers correct?  I don't think Ms Jurado is/was dead.  Ms Jurado is getting warmer.  I think she was just hypothermic and is coming around....she WAS 88 then 30 minutes later she was 92...

Already posted an answer to this......see previous

Press the ' 2nd ' key before pressing the respective function key to get the inverse of that function.

Would need to know the credits each course is worth

would need to know if advanced placement courses give more points for the letter grades

Generally  A=4   B=3  C=2  D=1

Multiply course credits times grade value, add all these numbers together then divide by the number of total credits.

Not sure what you are looking for, but

(5x-2)(4x-8)=

20x^2 - 40x - 8x +16 =

20x^2-48x+16

I don't think you can easilty factorise this equation....you can use the QUADRATIC FORMULA to find the roots and THEN set it up as two factors....

cos(theta) = 20.8/33.6

cos(theta) = .61904

theta = cos^(-1) (.61904) = 51.7533 degrees     (explaination:   cos^(-1)   is inverse cosine  also called arc cos)

log (256) = log(2^(n-1))

log(256) = (n-1)log(2)

log (256)/log(2) = n-1

8=n-1

9=n

'Incorrect' is what it is.

4x-8 cannot equal 4x+10
