Answer:
160 is a whole angle so 37+72=109 160-109=51
51 is your answer
Step-by-step explanation:
Divide both 6 and 10 by 2 to get 3/5
Multiply both 6 and 10 by 2 to get 12/20
Answer:
Step-by-step explanation:
y = -x^2+4x-6x +24
y = -x^2 -2x + 24
Vertex (x) = 2/-2 = -1
Vertex (y) = -100/ -4 = 25
Vertex (-1, 25)
axis of symmetry: x= -1
-x^2 -2x + 24 = 0
Δ/4 = 1+24 = 25
x1 = (1 + 5)/-1 = -6
x2 = (1-5)/-1 = 4
left x intercept = (-6,0)
right x intercept = (4,0)
The DOMAIN is the set of all numbers
The range is y less than or equal to 25
Use the Cosine Rule
q^2 = 20^2 + 30^2 - 2^20*30 cos 15
= 140.89
so q = sqrt 140.89 = 11.9 (answer)
