X=60° (equilateral triangle)
y=120°
Working: (360°-120°)/2
Factors are (3x + 5) and (x - 2). Zeros are -5/3 and 2.
Step-by-step explanation:
- Step 1: Given quadratic equation 3x² - x = 10 ⇒ 3x² - x - 10 = 0
- Step 2: Use factoring method (product and sum rule) to find factors and zeros. So the equation can be written as below.
⇒ 3x² - 6x + 5x - 10 = 0
⇒ 3x(x - 2) + 5(x - 2) = 0
⇒ (3x + 5)(x - 2) = 0 These are the factors of the equation.
- Step 3: Find zeros by equating the factors to 0.
⇒ 3x + 5 = 0 and x - 2 = 0
⇒ x = -5/3 and 2
Answer:
Step-by-step explanation:
When you follow the curve from the left toward x=2, you wind up at the open circle at (2, 4). The limit from that direction is 4.
When you follow the curve from the right toward x=2, you wind up at the open circle at (2, -4). The limit from that direction is -4.
Answer:
p is false, q is true and r is true
Step-by-step explanation:
- For (p ∨ q) → (r → p) to be false, the proposition (p ∨ q) must be true and (r → p) false.
- If (r → p) then r must be true and p is false, we now have truth values for these two
- Now if (p v q) is true, either p, q or both must be true. Since p is false, it follows that q must be true.
