Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.
Answer:
D
Step-by-step explanation:
The perimeter P of a rectangle is calculated as
P = 2l + 2w ( l is the length and w the width ) , then
2l + 2(9) = 5364
2l + 18 = 5364 ( subtract 18 from both sides )
2l = 5346 ( divide both sides by 2 )
l = 2673
Then
A = lw = 2673 × 9 = 24057 m² → D
Answer:
- The graphed is attached.
- It's an enlargement.
Step-by-step explanation:
A Dilation is defined as a transformation in which the image and the pre-image have the same shape, but their sizes are different.
When the scale factor is greater than 1, the image obtained after the dilation is greater than the pre-image and it is an "Enlargement".
When the scale factor is is between 0 and 1, the image obtained after the dilation is smaller than the pre-image and it is an "Reduction".
In this case we know that the scale factor is 4.
Since:
![4>1](https://tex.z-dn.net/?f=4%3E1)
So it is an Enlargement.
Now we need to multiply the coordinates of the vertices of VWXY by 4, in order to find the coordinates of the vertices of V'W'X'Y'. These are:
![V'=(-1*4,-1*4)=(-4,-4)\\\\W'(-1*4,2*4)=(-4,8)\\\\X'(2*4,-1*4)=(8,-4)\\\\Y'=(2*4,2*4)=(8,8)](https://tex.z-dn.net/?f=V%27%3D%28-1%2A4%2C-1%2A4%29%3D%28-4%2C-4%29%5C%5C%5C%5CW%27%28-1%2A4%2C2%2A4%29%3D%28-4%2C8%29%5C%5C%5C%5CX%27%282%2A4%2C-1%2A4%29%3D%288%2C-4%29%5C%5C%5C%5CY%27%3D%282%2A4%2C2%2A4%29%3D%288%2C8%29)
Now we must draw the pre-image and the pre-image and label them, as you see in the picture attached.
