Answer:

75m

Step-by-step explanation:

  • let X be the length of the pole
  • 1/5 of the pole is in water so =1/5X
  • 2/3 of the pole is in mud= 2/3X
  • 10m is above the pole
  • length of the pole (X)= length of pole in mud+length of pole in water+length of pole in air
  • X(m)=1/5X+ 2/3X+10
  • X- 13/15X=10
  • 2X= 10x15
  • X=75m

Consider a sequence generated by the formula f(n) = 6n − 4 starting with n = 1. Generate the terms f(1),
Ierofanga [76]

Answer:

See explanation below

Step-by-step explanation:

To get all the terms in this sequence, all you need to do is to put the values of n, starting from 1 to 5 in the formula.

The part where n is, you just put the value given.

To get for example f(5), you only need to put n = 5 in the formula, do the math and then get the result.

Here are the values of f1, f2, f3, f4 and f5. Again, we will use the following values for n: 1,2,3,4,5

f(1) = 6(1) - 4 = 6 - 4 = 2

f(2) = 6(2) - 4 = 12 - 4 = 8

f(3) = 6(3) - 4 = 18 - 4 = 14

f(4) = 6(4) - 4 = 24 - 4 = 20

f(5) = 6(5) - 4 = 30 - 4 = 26
