The answer should be
780x + 1500y=31000
please correct me if i'm wrong
Male 0.271 0.198
Female 0.229 0.302
I think that's right because that's what my quiz said
2x^(3)y+7xy-3x^(2)-12y
is in standard form
Regroup: (4x³-12x²)+(7x-21)
factor: 4x²(x-3)+7(x-3)
factor again: (x-3)(4x²+7)
Answer:
4/5
Step-by-step explanation:
In a right triangle such as this one
cos (angle) = adjacent leg / hypotenuse
cos(k) = KL / 15
You will need to find the leg length KL using Pythagorean Theorem
15^2 = 9^2 + (KL)^2 KL = 12
then cos k = 12/15 = 4/5
