Find the x-values (if any) at which is not continuous.​

Two-factor authentication provides enhanced security by requiring only a single password.

Decide whether the following problem can be solved using precalculus, or whether calculus is required. If the problem can be solved using precalculus, solve it. If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. ​ Find the area of the shaded region. ​ ​

What is the primary function of a motherboard in a computer system?

A cloud-based application differs from traditional desktop software in that:

A real object is 3.7 cm tall. The object is placed on the left side of a thin lens with a focal length of 18 cm. The object forms an upright image by the lens. If d2 = 15 cm, what is the height of the image?

In the figure, a [h]-cm-tall object is located in front of a thin lens with a refractive power of [P] diopters. If d = 0.4 m, what is the height of the image (measured in cm)? Express the answer as a positive quantity.

In a double-slit experiment, the slit separation is 4.0 × 10-3 m. Monochromatic light of wavelength 500 nm illuminates the two slits and produces an interference pattern on a distant screen. Consider only the fringes on one side of the central maximum. If the linear distance on the screen between the second-order dark fringe and the sixth-order bright fringe is 3.0 × 10-3 m, what is the distance between the slits and the screen.

In a double-slit experiment, it is observed that the distance between adjacent maxima (bright fringes) on a remote screen is 1.0 cm.  What happens to the distance between adjacent maxima when the slit separation is cut in half?  

In a double-slit experiment, the slit separation is 30 × 10-6 m. The interference pattern is created on a screen that is 2 m away from the slits. If the 7th bright fringe on the screen is 10× 10-2 m away from the central maximum, what is the wavelength of the light? Express the answer in nanometers, nm.
