What is the 17th term in the arithmetic sequence described by this explicit formula? a(n)=77+ (n-1) (-5)

= - 3

Step-by-step explanation:

to find the 17 th term substitute n = 17 into the explicit formula

A(17) = 77 + (16 × - 5 ) = 77 - 80 = - 3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
