PLEASE HELP ASAPPPPP

Mathematics
1 answer:
sveticcg [70]2 years ago
4 0

Answer:

506.7 cm²

Step-by-step explanation:

The amount of cardboard needed would be the surface area of the cone,

S= pi(r)(l+r) where r is the radius and l is the slant height.

You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.

Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²

Let me know if you have any questions about my steps!

What is the exact solution to the equation 2^2x=5^x−1 ?
Ann [662]

2^2x=5^x−1

Take the log pf both sides:

ln(2^2x) = ln(5^x-1)

Expand the logs by pulling the exponents out:

2xln(2) = (x-1)ln(5)

Simpligy the right side:

2xln(2) = ln(5)x - ln(5)

Now solve for x:

Subtract ln(5)x from both sides:

2xln(2) - ln(5)x = -ln(5)

Factor x out of 2xln(2)-ln(5)x

x(2ln(2) - ln(5)) = -ln(5)

Divide both sides by (2ln(2) - ln(5))

X = - ln(5) / (2ln(2) - ln(5))
