I think it’s g^-1(x)= -2x+4
The “^” means exponent to -1 is the exponent of g
Hope I’m right !!
Answer:
V = 128π/3 vu
Step-by-step explanation:
we have that: f(x)₁ = √(4 - x²); f(x)₂ = -√(4 - x²)
knowing that the volume of a solid is V=πR²h, where R² (f(x)₁-f(x)₂) and h=dx, then
dV=π(√(4 - x²)+√(4 - x²))²dx; =π(2√(4 - x²))²dx ⇒
dV= 4π(4-x²)dx , Integrating in both sides
∫dv=4π∫(4-x²)dx , we take ∫(4-x²)dx and we solve
4∫dx-∫x²dx = 4x-(x³/3) evaluated -2≤x≤2 or too 2 (0≤x≤2) , also
∫dv=8π∫(4-x²)dx evaluated 0≤x≤2
V=8π(4x-(x³/3)) = 8π(4.2-(2³/3)) = 8π(8-(8/3)) =(8π/3)(24-8) ⇒
V = 128π/3 vu
Answer:
A. 30
Step-by-step explanation:
Because it showed up the most
12.5×12.5 will give u 42 an if u add it u will get 25
Answer:
to find the distance between two points, in order to find the length of the triangle we need first to find the instance between the two points
distance between (2,9) and (2,4) .....a =5
distance between (2,4) and (6,4) .....b = 4
when we find the length of the side of the triangle , then we can apply the Pythagorean theorem to find hyp. c
a²+b²=c²
