The area is
f(x) = x(x - 3).

The area cannot be zero.
However, f= 0 when x = 0 or when x = 3.
Therefore the domain includes x >3.

Answer: C. all integers greater than 3.

Which function has the same y-intercept as the line graphed below?
KatRina [158]

Answer:

D. y + 4 = 2x  

Step-by-step explanation:

The graph has a y-intercept at (0, -4).

A. y=16 - 3x/4

if x = 0, y = 16. FALSE.

B. 24 + 3y = 6x

If x = 0, 24 + 3y =     0

                     3y = -24

                       y =    -8. FALSE.

C. 4y + x = 16

If x = 0, 4y = 16

              y =   4. FALSE.

D. y + 4 = 2x

If x = 0, y + 4 =  0

           y       = -4. TRUE.

y = 4 + 2x has the same y-intercept as the graphed line.

Use logarithmic differentiation to find dy/dx if y=(cosx)sinx. Write the derivative in terms of x only. Show all your work.
gladu [14]

Step-by-step explanation:

y = (cos x)^(sin x)

Take log both sides.

ln y = ln ((cos x)^(sin x))

ln y = (sin x) ln (cos x)

Take derivative.

1/y dy/dx = (sin x) (1/cos x) (-sin x) + (cos x) ln (cos x)

dy/dx = y [ (cos x) ln (cos x) − sin x tan x ]

dy/dx = (cos x)^(sin x) [ (cos x) ln (cos x) − sin x tan x ]

Your answer is correct.
