Determine the smallest integer value of x in 5x + 3 ≥ 10

Ivanshal [37]

5x + 3 ≥ 10

3 is adding on the left, then it will subtract on the right

5x ≥ 10 -3

5x ≥ 7

5 is multiplying on the left, then it will divide on the right

x ≥ 7/5

x ≥ 1.4

Then, the smallest integer value of x is 2

17. Which of the following is the correct formula for finding power in a DC circuit? A. P = I2R B. P = VR C. P = IR D. P = V2I

netineya [11]

Answer:

Choice A. P = I² · R where

P is the power in the DC circuit,
I is the current through the circuit, and
R is the total resistance of the circuit.

Step-by-step explanation:

Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work $W$ that the electrical force do when it moves charges $Q$ across a potential difference $V$ :

W = $V\cdot Q$ .

The power is the rate at which the electrical force do the work:

$\displaystyle P = \frac{W}{t} = V \cdot \frac{Q}{t}$ .

On the other hand, current $I$ is the charge through a cross-section of the circuit in unit time. By the definition of current:

$\displaystyle\frac{Q}{t} = I$ .

$\displaystyle P =V \cdot \frac{Q}{t} = V\cdot I$ .

Consider Ohm's Law:

$V = I \cdot R$ .

Therefore

$\displaystyle P = V\cdot I = (I \cdot R) \cdot I = I^{2}\cdot R$ .

Zepler [3.9K]

Answer:

14,621 lbs.

Step-by-step explanation:

It says at the beginning of the question that the school district collected 14,621 lbs. of recycling. The part where it says that the school district collected 3,943 lbs. of recycling more than last year is un-needed information.
