Ticket charges = $150

Each bag carry cost = $20

Find:

Relationship between bag(b) and cost(c)

A dome of a building is in the form of a hemisphere from inside it was whitewashed at the cost of rupees 4989.60 if the cost of

Luda [366]

Answer: $249.48\ m^2; 369.168\ m^3$

Step-by-step explanation:

Given

Cost of white-washing =Rs. 4989.60

Rate =20 per meter square

So, inside area of = $\dfrac{4989.60}{20}=249.48\ m^2$

The surface area of dome= $4\pi\ r^2=249.48$

$4\times 3.142\times r^2=249.48\\r^2=\frac{249.48}{4\times 3.142}=19.85\\r=4.455\ m$

The volume of air in the dome $V=\frac{4}{3}\pi r^3$

$V=\frac{4}{3}\cdot 3.142\cdot (4.45)^3\\V=369.17\ m^3$

F(n+1)=f(n)-3 f(1)=15

Trava [24]

Answer:

f(n+1) = 13

Step-by-step explanation:

We know that f(1) = 15
So we can substitute this for f(n)-3
With this:

f(n+1) = f(1) -3
f(n+1) = 15-2
f(n+1) = 13
