Answer:
2x-2
Step-by-step explanation:
h(gx)=h(x+1)
=2(x+1)-4
=2x-2
You have to kind of go backwards on this one. So, he goes down 10 floors to the first so he’s on the 10th, down 7 floors= 3rd floor up 5 floors= 8th floor
Answer:
10.45
Step-by-step explanation:
A=pi10^2*63/360-10*10 sin63/2=3.14*6300/360-50*0.89
A=3.14*17.5-44.5=54.95-44.5=10.45
or if I do not complete pi=3.14
A=17.5 pi-44.5
By definition. The volume of the sphere is:
V = (4/3) * (pi) * (r ^ 3)
Where,
r: radius of the sphere.
Substituting values:
2254 pi = (4/3) * (pi) * (r ^ 3)
Clearing the radio we have:
r ^ 3 = (3/4) * (2254)
r = ((3/4) * (2254)) ^ (1/3)
r = 11.91255883
Then, the surface area is:
A = 2 * pi * r ^ 2
Substituting values:
A = 2 * 3.14 * (11.91255883) ^ 2
A = 891.6 m ^ 2
Answer:
The surface area of the sphere is:
b. 891.6 m ^ 2
