Write a recursive formula for the sequence {10, 12, 14, 16, ...}. f(1) = 10, f(n) = f (n - 1) + 2, for n> 1

f(1) -2, f(n) = |(n-1) - 10, for n> 1

f(1) = 2, f (n) = f(n − 1) + 10, for n> 1

f(1) = 10, f (n) = f (n − 1) - 2, for n> 1​

Adepartment store purchases screen-printed t-shirts at a cost of $5 per shirt. they mark up the price 150% (making the selling price 250% of the store's purchase price) and put them on the sales floor. every month that a t-shirt doesn't sell, the store reduces the selling price by 25%.

Arley is building a model of a city map. in one part of the city, three roads form a right triangle, which harley draws as triangle abc, with the following measures: m∠b=90° and m∠a=30°. in his scale model, the hypotenuse of triangle abc, ac¯¯¯¯¯¯¯¯, has a length of 817−−√ cm. what is the value of a (the length of bc¯¯¯¯¯¯¯¯)?

What is the equation of the line in point-slope form? y+ 4 = 1/2(x+4) y-4 = 1/2(x + 4) y-0 = 2(x - 4) y-4 = 2(8-0)
