2/3=3r cross multiply
9r=2 divide both sides by 9
r=2/9
cos-1 (52/45) =1.15556???..........which is NOT correct. Cos. must be between -1 and +1.
You are talking about the Pythagorean Theorem, correct?
It should be \(\sqrt{15^2+8^2}=c\)
So \(\sqrt{189}=c\)
sqrt(189)=c = c=3*sqrt(21)
Are you aware of how messy an orange can be?
Would you want to be the person that must use the desk following the person who ate an orange and didn't clean the desk extremely well?
(Of course, you never spill soda-pop or leave chip particles or leave orange gunk behind ...)
Assuming that this is a probability question using a normal distribution:
normalcdf(-1.69,1.28) = 0.854 (approximately)
That's not good! I hope we can fix that along with lots of other things that are happening.
2y3 · 4y3 = (2 · 4) · (y3 · y3) = 8y6 (multiply 2 x 4 and add the exponents of the y-terms)
-x4 · 3y-3 · 5y6 · 6x-9 = (-1 · 3 · 5 · 6) · (x4 · x-9) · (y-3 · y6) = -90x-5y3 (again, multiply the numbers and add the exponents of the like terms)
if you mean 15y-6xy=0 the answer is simple:
15y-6xy=0
<=> y(15-6x)=0
<=> y=0 V 15-6x=0
<=> y=0 V 15=6x
<=> y=0 V 15/6=x
<=> y=0 V 5/2=x

Don't worry, I have to do a memory recital of 25 lines of Romeo and Juliet. Good luck on your tests though!
Mathfordays, it is actually 5y2-2y
Yes, they are exactly the same!
y(5y-2)=y*7y
1 whole year!
she the only teacher to embrace it?>?>?>?
