Answer:

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm

Step-by-step explanation:

Given

Per day cost of running centrifugal pump is $30

Charge of electricity is 9.7 cents per kilowatt hour

Total electricity power consumed

\frac{30}{0.097} \\309.278 kilowatt hour

Current flowing through the pump

= \frac{309.278}{240} \\= 1.288A

Resistance of the pump

\frac{1.288}{240} \\0.005 ohm

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm

Which of the following points is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2?
MA_775_DIABLO [31]

Answer:

A (0,3)

Step-by-step explanation:

The given trapezoid has vertices:

(0,6), (7,12), (7,9) and (0,12).

We want to choose from the given options, a point that is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2.

Note that the mapping for such a dilation is:

(x,y)\to( \frac{1}{2} x, \frac{1}{2} y)

This implies that:

(0,6)\to(0,3)

(7,12)\to(3.5,6)

(7,9)\to(3.5,4.5)

(0,12)\to(0,6)

Therefore correct choice is (0,3)

PLZ HELP IDK WHAT THIS MEANS
Hoochie [10]

Answer: Option B.

Step-by-step explanation:

In the graph we can see the graph of a quadratic equation (from this we could conclude that the graph will not change the current direction for the arms, so the arms will keep going down), and we also can see that as x increases in absolute value, the value of y decreases.

Then we could conclude that as IxI is really big, we will have that f(x) goes to minus infinity

x -->∞, f(x) --> -∞

x--> -∞, f(x) --> -∞

Then the correct option is B
