Answer:

AB = 10

BC ≈ 11.40

Step-by-step explanation:

The distance formula is useful for finding distances between points.

d = √((x2 -x1)² +(y2 -y1)²)

AB = √((18 -10)² +(4 -10)²) = √(8² +(-6)²) = √100

AB = 10

BC = √((25 -18)² +(-5-4)²) = √(7² +(-9)²) = √130

BC ≈ 11.40

Hatshy [7]

X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.

x + y = 2400/5 = 480 - flying with the wind

adding the 2 equations
2x = 880
x = 440

Speed of the plane with no wind = 440 mph

The electric heaters, in a 240 volt electric furnace, draw 40 amps of current. What is the total KW rating of the heaters?

Answer:

9.6 kW

Step-by-step explanation:

The product of volts and amps is watts. Here, that product is ...

(240 V)(40 A) = 9600 W

1000 W is 1 kW, so this quantity is 9.6 kW

This tells the power consumption. The "rating" may be different.

Use Newton's method with initial approximation x1 = 1 to find x2, the second approximation to the root of the equation x4 − x −

drek231 [11]

Answer:

$x_{2} = 0.0000$

Step-by-step explanation:

The formula for the Newton's method is:

$x_{i+1} = x_{i} + \frac{f(x_{i})}{f'(x_{i})}$

Where $f' (x_{i})$ is the first derivative of the function evaluated in $x_{i}$ .

$x_{i+1} = x_{i} + \frac{x_{i}^{4}-x_{i}-3}{4\cdot x_{i}^{3}-1}$

Lastly, the value of $x_{2}$ is determined by replacing $x_{1}$ with its numerical value:

$x_{2} = x_{1} + \frac{x_{1}^{4}-x_{1}-3}{4\cdot x_{1}^{3}-1}$

$x_{2} = 1.0000 + \frac{1.0000^{4}-1.0000-3}{4\cdot (1.0000)^{3}-1}$

$x_{2} = 0.0000$
