Guys, please help me please

Mathematics
1 answer:
Gekata [30.6K]3 years ago
7 0

Answer:

150.72

Step-by-step explanation:

To find the surface area, use the provided formula and the values r = 2 and h = 10. The radius of the object is 2 since it is half the distance across the circle which measures 4 inches across through the center.

SA = 2πr² + 2πrh

SA = 2π2² + 2π(2)(10)

SA = 2π*4 + 2π(20)

SA = 8π + 40π

SA = 48π

SA = 48(3.14)

SA = 150.72

I need help pleaseee
kumpel [21]

Answer: $7448

Step-by-step explanation:

Year 1: 1.218x

Year 2: 1.218(1.218x)

Year 3: 1.218(1.218(1.218x))

Year 4: 1.218(1.218(1.218(1.218x)))

Year 5: 1.218(1.218(1.218(1.218(1.218x))))

Year 6: 1.218(1.218(1.218(1.218(1.218(1.218x)))))

Year 7: 1.218(1.218(1.218(1.218(1.218(1.218(1.218x))))))

Year 8: 1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218x)))))))

Year 9: 1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218x))))))))

Year 10: 1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218x)))))))))

Year 11: x(1.218¹¹)

Year 12: x(1.218¹²) = 79,400

         

x(10.6602517) = 79,400

x = 79,400/10.6602517

x=7448.22939

x = $7448

Hope this helps!

gayaneshka [121]
Since this can’t be factored easily, you have to use synthetic division. This makes the answer x+4+(-1/x+5)
