Please help will give brainliest please hurry Write the recursive formula for the explicit formula below:

A(n)=3+(n-1)(-5)

Select one:

a.

A(1) = 3

A(n) = A(n-1) - 2

b. A(1) = 3

A(n) = A(n-1) - 5

c.

A(1) = 5

A(n) = A(n-1) - 3

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96

List x1, x2, x3, x4 where xi is the left endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 4 and x = 6. a 4, 4.5, 5, 5.5 b 4.5, 5, 5.5, 6 c 4.25, 4.75, 5.25, 5.75 d 4, 4.2, 5.4, 6

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3
