B varies inversely with c. When B is 2, C is
8. Find the value of c when B is 5.

Solution:

Given that,

B varies inversely with C

Which means,

When B is 2, C is  8

Substitute B = 2 and C = 8 in eqn 1

Find the value of c when B is 5.

Substitute B = 5 and k = 16 in eqn 1

Thus the value of C when B is 5 is 3.2

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
