Identify the recursive formula for the sequence 900, 850, 800, 750, . . . Question 5 options:

f(n)={f(1)=900f(n)=f(n−1)+50ifn> 1

f(n)={f(1)=850f(n)=f(n−1)−50ifn> 1

f(n)={f(1)=900f(n)=f(n−1)−50ifn> 1

f(n)={f(1)=900f(n)=f(n+1)−50ifn> 1

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
