8 0

Answer:

a)   P₁  = 250 and    P₂ = 300

b) The explicit formula   Pₙ = 150+ 50 n

c)  P_{60}  = 3150

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that Pₙ = pₙ₋₁ +50 and P₀ = 200

Put n =1

         P₁ = P₀+50 = 200+50 = 250

Put n =2

         P₂ = P₁+50 = 250+50 = 300

Put n=3

       P₃ = P₂+50 = 300+50 = 350

and so on

The sequence     200,250,300,350,..

<u><em>Step(ii):- </em></u>

The sequence     200,250,300,350,.. is an arithmetic sequence

The explicit formula

       Pₙ = a+(n-1)d

       Pₙ = 200+(n-1)50

       Pₙ = 200+ 50 n -50

        Pₙ = 150+ 50 n

The explicit formula   Pₙ = 150+ 50 n

c)

The n^{th} term of the sequence

       Pₙ = 150+ 50 n

put n=60

      P_{60} = 150 + 50 (60) = 3150

An advertisement for a circular rug says that the rug has a diameter of 6 feet. Find the relative error of this measurement
Aleonysh [2.5K]

Answer:

1. 8.3%

Step-by-step explanation:

Relative error = absolute error/expected measurement

The expected measurement is given as 6 ft.

Now, the absolute error is usually equal to half of a unit of the measure.

This means the absolute error in this case is ½ × 1 = 0.5 ft

Thus, the exact measurement will be;

6 ± 0.5

Thus;

Relative error = 0.5/6

Relative error = 0.083

Expressing it in percentage gives 8.3%

Is x = 12 a solution to the equation 6 + x = 19
gladu [14]

Answer:

Incorrect.

Step-by-step explanation:

6 + x = 19

Plug in when x = 12

6 + 12 = 19

18 = 19

It is incorrect, so 12 is not a solution.
