What is the median 3 2 -9 9 -3 -5 3 -4 -1

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
