Answer:

B) maximum value at 39.

Step-by-step explanation:

maximum value at 39

First, set the expression equal to 0.

−x2 − 10x + 14 = 0

Complete the square.

−x2 − 10x = −14

−(x2 + 10x) = −14

−(x2 + 10x + 25) = −39

−(x + 5)2 + 39= 0.

Therefore, the maximum value is 39.

Given that log3(z - 1) - logz z = 1+ 3 log3 y, express z in terms of y.
fgiga [73]

Answer:

  z = 1 + 9y³

Step-by-step explanation:

It looks like you have ...

  \log_3{(z-1)}-\log_z{(z)}=1+3\log_3{(y)}\\\\\log_3{(z-1)}-1=1+\log_3{(y^3)}\\\\\log_3{(z-1)}=2+\log_3{(y^3)}\qquad\text{add 1}\\\\z-1=(3^2)(y^3)\qquad\text{take antilog}\\\\\boxed{z=1+9y^3}\qquad\text{add 1}
