Answer: 4 V

Step-by-step explanation:

The formula for electrical power P is:

P=\frac{V^{2}}{R}

Where:

P=0.5 W is the water heater electrical power

V is he water heater voltage

R=32 \Omega is the electrical resistance

Isolating V:

V=\sqrt{PR}

V=\sqrt{(0.5 W)(32 \Omega)}

Hence:

V=4 V

Explain how to multiply 5.2 times 0.6​
Sonja [21]

Answer:

3.12

Step-by-step explanation:

Line up the number in long multiplication form as usual

Multiply each digit on the top by the first to the right on the bottom

Add the products together

Place the decimal the number of digits it is collectively in front of in each factor

Example 5.2 has one behind the decimal and .6 also has one digit behind the decimal collectively that would be two digits behind the decimal.

In DEF, C is the centroid if DM=45 , find DC and CM<br><br><br><br> DC= ? Units
IgorC [24]

Answer:

DC=30

CM=15

Step-by-step explanation:

Given

Triangle DEF with C centroid

DM=45 (length of median)

centroid divides median in the ratio 2:1(larger side at vertex)

⇒

DC=\frac{2}{3} \times DM=\frac{2}{3} \times 45= 2\times 15=30

⇒DC=30

DC+ CM=DM

30+CM=45

⇒CM=15

I need help please!!!!
zaharov [31]

Answer:

  (c)  y -2 = 6/5(x -1)

Step-by-step explanation:

The equations are all in point-slope form with a slope of 6/5. The points used are (-1, -2), (-2, -1), and (1, 2). It seems point (1, 2) best matches a point on the graphed line. Choice C is the best. (In the attached graph, choice C is the red line.)

_____

<em>Additional comment</em>

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

__

The equation might be easier to see if the point chosen were one at a grid intersection, such as (-4, -4) or (6, 8).
