Answer:
x=13i, -13i
Step-by-step explanation:
Take the square root of both sides which gives you plus or minus the square root of -169. Then you get plus or minus 13times the square root of negative 1. Now you can say that x equals positive or negative 13i
Answer:
PQ is 50
Step-by-step explanation:
the total is 69 so all you have to do is take what is known, in this case 19 and do 69 minus 19 to get 50
The answer is D. 13.5 and 20.25
Answer:
C. Neither linear nor non linear
Step-by-step explanation:
The company spends $3 on each basketball it produces, which means if the company produces
basketballs, then the amount
it would have spent is
.
Now, the rate of cost growth is the rate of change, or the derivative of the amount spent
; therefore,
![\dfrac{dy}{db} =\dfrac{d(3b)}{db} = 3 \dfrac{db}{db} =3](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdb%7D%20%3D%5Cdfrac%7Bd%283b%29%7D%7Bdb%7D%20%3D%203%20%5Cdfrac%7Bdb%7D%7Bdb%7D%20%3D3)
which is a constant, which means the rate of cost growth is not increasing. Therefore, rate of cost growth at the factory is neither linear nor nonlinear.
