ANSWER:
The surface area of the star is 3.2700 x 
square kilometres.
EXPLANATIONS:
Diameter of the star = 1.8083 x 
Km.
Surface area of the star = 4
Where n is the radius of the star.
So that;
n = 
= 0.90415 x
n = 0.90415 x Km
Thus,
Surface area = 4 x 
= 326994889
Surface area = 3.2700 x 
Therefore, the surface area of the star is 3.2700 x square kilometres.
Answer:
84
Step-by-step explanation:
f(x) = 3x^2 + 2x – 1
Let x=5
f(5) = 3(5)^2+2(5) -1
= 3*25 +10-1
= 75+10 -1
= 85 -1
Answer:
g(L) = 175L - L²
Step-by-step explanation:
350 = 2(length + width)
length + width = 175
Let L be the length,
L + width = 175
width = 175 - L
Area = length × width
g(L) = L(175 - L)
g(L) = 175L - L²
Answer:
side CB
Step-by-step explanation:
draw triangles ABC and ACD next to each other
The longer leg of the triangle ABC is CB, which corresponds with the longest leg of ACD, which is side CD
