Answer:
A. 0.186524036
Step-by-step explanation:
Cosine 79° 15'
But, 1° = 60'
Thus; 15' = 15/60 = 0.25°
Therefore;
cos 79° 15' = cos 79.25°
Cos 79.25° = 0.186524036
= 0.186524036
Answer:
x^2 -10x+2
Step-by-step explanation:
(3x^2 - 11x - 4) – (x – 2) (2x + 3)
FOIL
(3x^2 - 11x - 4) – (2x^2-4x+3x-6)
Combine like terms
(3x^2 - 11x - 4) – (2x^2 -x-6)
Distribute the minus sign
3x^2 - 11x - 4 – 2x^2 +x+6
Combine like terms
x^2 -10x+2
Answer:
Porpotional
Step-by-step explanation:
because it is non proportional
Answer:
θ=1.2 rad=68.7549°
Step-by-step explanation:
Given
- Circle of radius 5
- Arc of length 6 subtends angle of θ
⇒
θ
Therefore θ=1.2 rad
(π rad= 180°)
Therefore 1.2 rad= 68.7549°
