The original equation is cos 64 = 32/k. To solve for k we need to isolate it. we can multiply by k then divide by cos 64. This gives us the equation k = 32/cos 64. Therefore, B is the right answer.
I believe the correct answer from the choices listed above is the last option. The function that represents the total cost to build the dog house would be <span>c(p)=12p+65. Hope this answers the question. Have a nice day.</span>
