Answer:

The value of Mary's investment after two years = £12362.7

Step-by-step explanation:P = Principal / initial amountR = rate of interest per cent per yearT = number of yearsA = final amount at the end of T yearsThen:A = P*(1 + R/100)^2In our example:P = £12000R = 1.5 per cent per yearT = 2 yearsThus:A = 12000*(1 + 1.5/100)^2   = 12000*(1 + 0.015)^2   = 12000*(1.015)^2    = 12000*(1.030225)    = 12362.7Value of investment after two years = £12362.7

17, 13, 9,5...<br> determine the sequence
ValentinkaMS [17]

This is an arithmetic sequence because we are adding the same amount each time. In this case, we are adding -4 to each term to get the next term

17 + (-4) = 13

13 + (-4) = 9

9 + (-4) = 5

and so on. The starting term is a_1 = 17

The common difference is d = -4

The nth term of the arithmetic sequence can be found by this formula

a_n = a_1 + d(n-1)\\\\a_n = 17 + (-4)(n-1)\\\\a_n = 17 - 4n + 4\\\\a_n = -4n+21

For instance, if n = 2, then,

a_n = -4n+21\\\\a_2 = -4(2)+21\\\\a_2 = -8+21\\\\a_2 = 13

which matches up with the second term listed.

V=3,054 inches^3

Hope this helps!!!!!!!!!

Step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.
