In your point, y is 3 and x is 2. You have to fill in these values for x and y into each equation in A-D to see which one is "true". Let's start with A. y = -3x. Filling in 3 for y and 2 for x gives us 3 = -3(2). Does 3 equal -6? Of course not. So let's try B. y = x - 1. 3 = 2 - 1. Does 3 = 1? Of course not! Let's try C. y = 3x...3 = 3(2). 3 doesn't equal 6 either, so...last one. y = x + 1 is 3=2+1. Does 3 = 3? Yes! Finally! So the point on the coordinate plane is one the line represented by D.
Answer: 1384.74
Step-by-step explanation:
A=πr^2
radius=42/2=21
(3.14)(21)^2
3.14(441)
1384.74
Step-by-step explanation:
tan⁻¹(x) = ∑ₙ₌₀°° (-1)ⁿ x²ⁿ⁺¹ / (2n+1)
tan⁻¹(1/√3) = ∑ₙ₌₀°° (-1)ⁿ (1/√3)²ⁿ⁺¹ / (2n+1)
tan⁻¹(1/√3) = ∑ₙ₌₀°° (-1)ⁿ (1/√3) (1/√3)²ⁿ / (2n+1)
tan⁻¹(1/√3) = (1/√3) ∑ₙ₌₀°° (-1)ⁿ (1/3)ⁿ / (2n+1)
π/6 = (1/√3) ∑ₙ₌₀°° (-1)ⁿ (1/3)ⁿ / (2n+1)
π = (6/√3) ∑ₙ₌₀°° (-1)ⁿ (1/3)ⁿ / (2n+1)
π = 2√3 ∑ₙ₌₀°° (-1)ⁿ / (3ⁿ (2n+1))
The graph of a function must be linear if x is not squared in the function
Answer:
What is 10% of 120?
Step-by-step explanation:
120 / 10 = 12
10% of 120 = 12
We have a match.
Let's do the others, just to be sure it's the only one.
10% of 12 = 1.2
25% of 120 = 30
25% of 120 = 3
