Answer:
-4x³ + 4xy
Step-by-step explanation:
distribute -4x by 'x²' and '-y'
-4x(x²) = -4x³
-4x(-y) = 4xy
Answer:
(0.58)⁴ (0.42)¹
Step-by-step explanation:
42% of people who get their eyes examined are nearsighted.
So 58% of people who get their eyes examined are not nearsighted.
The probability that the ophthalmologist examines 4 people who are not near sighted, followed by 1 person who is nearsighted, is:
P = (0.58)⁴ (0.42)¹
Answer:
1. We already have the measure of the hypotenuse and one out of two acute angle, therefore:
sin53° = x/45 => x = sin53° · 45 ≈35.94
2. We already have one out of two legs of the triangle and one acute angle so we know that:
tan27° = 48/x => x = 48/tan27° ≈ 94.21
Answer:
x^2 +x+2
Step-by-step explanation:
f(x) = x^2+3
g(x) = x-1
f(x)+ g(x) = (f+g) (x)
x^2+3+ x-1
x^2 +x+2
