Answer:
1. Sine ratio of angle ∠C = 12/13
2. cos ratio for ∠C = 6/10
Step-by-step explanation:
1. sin = perpendicular /hypotuse
=> 12/13
2. cos = base / hypotuse
=> 6/10
Answer:
Zero is even (not odd, not neutral)
Zero is neither positive nor negative (the only number with this property)
Zero is an integer (and must be considered when question limits choices to integers)
Zero is a multiple of all numbers (x*0 = 0, so a multiple of any x)
Step-by-step explanation:
Any number to the power of 0 is equal to 1. 0 is neither positive nor negative. 0 is neither prime nor composite. If you add two numbers and the sum is zero, we call the two numbers additive inverses or opposites of each other.
Answer:
Step-by-step explanation:
- log₄ (m²) = log₄ (18 - 7m)
18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7
- m² = 18 - 7m
- m² + 7m - 18 = 0
- m² + 2*3.5m + 12.25 = 30.25
- (m + 3.5)² = 5.5²
- m = - 3.5 ± 5.5
