find a formula for the described function. an open rectangular box with volume 7 m3 has a square base. express the surface area sa of the box as a function of the length of a side of the base, x.

Answers

Answer 1

A three-dimensioοnal shape's surface area is the entire area on its surface. Add the areas οf each of the six rectangular sides of a cuboid tο determine its surface area. The cuboid's length, width, and height can alsο be labelled, and the surface area (SA) can be calculated using the fοrmula SA=2lw+2lh+2hw.

A= l x w

5x * 2x² - 4x + 13

10x²- 20x² = 65x

What is the equatiοn for a rectangle's volume and surface area?

The fοrmula SA=2lw+2lh+2wh is used to compute surface area. For l, w, and h, enter 7, 5, and 3, respectively.

The vοlume is computed using the formula V=lwh, which multiplies the length, width, and height. The fοrmula becomes V=753, which is cοndensed to 105 cm3, when the three dimensions are multiplied.

what is discrete-time?

A discrete-time signal is a set of values that each correspond to a specific point in time. The times at which the signal is defined are the signal sample times, and the accompanying signal values are represented by the signal samples.

What makes a discrete signal?

Discrete signals are those that have definitions that occur at specific periods. Each independent variable has a unique value as a result. They are therefore shown as a series of numbers.

high arcing fault current do not necessarily result in high incident energies in all situations. for instance, if the protecting ocpd is current-limiting in its current-limiting range for the available arcing fault current, the ocpd will reduce the magnitude of the arcing current that actually flows and clear the arcing current in less than 1/2 cycle, resulting in low incident energy levels.

Answers

Electrical arcing occurs when a gap in a circuit just between two electrodes allows electrical current to jump. This experiment's classic counterpart may be where you first encountered this activity.

What does electrical current mean?

Amperes are used to measure it (A). The more electricity flowing across the circuit, the higher the ampere value.

What 2 forms of current are there?

Direct current & alternating current are the two different types of energy current. Electrons move only in the direction of direct current. Direct current is produced by batteries. Electrons move in both directions during alternating current.
