A lightbulb has a power of 60 W and is used for 16 hours. A toaster oven has a power of 1500 W

krek1111 [17]

a. The lightbulb uses the energy of 960 W or 9.60 kW.

Step-by-step explanation:

Step 1:

To determine the energy used by the appliances we need to understand the equation

$power = \frac{energy}{time} .$

To determine the energy used, we multiply the power of the appliance with the amount of time it has been used for.

Step 2:

The lightbulb has a power of 60 W and is used for a period of 16 hours.

The energy used by the lightbulb $= 60(16) = 960$ W = 0.96 kW.

The toaster oven has a power of 1,500 W and is used for 0.75 hours.

The energy used by the toaster oven $= 1,500(0.75) = 1,125$ W = 1.125 kW.

The image of the point (-1, 7) under a translation is (0, 11). Find the coordinates of the image of the point (1, -4) under the

g100num [7]

If the image of the point (-1,7) under a translation be (0,11) then the coordinates of the image of the point (1,-4) under the same translation is (2,0).

Given that the image of the point (-1, 7) under a translation is (0, 11).

We are required to find the coordinates of the image of the point (1, -4) under the same translation.

Translation basically means the displacement of a figure or a shape from one place to another. In translation figure can move upward, downward, right, left or anywhere in the coordinate system.

The point (-1,7) after translation changes into (0,11).

X coordinate will change by adding 1 to it and Y coordinate will change by adding 4. Now the point (1,-4) will change to (2,0) after adding 1 to 1 and 4 to -4.

Hence if the image of the point (-1,7) under a translation be (0,11) then the coordinates of the image of the point (1,-4) under the same translation is (2,0).
