With A and its image one can get the dilation factor;
That is dilation scale factor = -6/-4 or 9/6 = 3/2
Therefore, to get the image of B we multiply the coordinates of B by the dilation factor; 
(1,4) 3/2 = (1.5, 6)
Thus the image of B = (1.5,6)

Answer:

To find the image of B, first find the scale factor for the dilation. The scale factor should be greater than 1 because the image of A is farther from the origin than A. Divide the coordinates of the image of A by the coordinates of A: –6/–4 = 3/2 and 9/6 = 3/2, so the scale factor is 3/2. Now, apply the dilation to B by multiplying the coordinates by 3/2 to get ((3/2)(1), (3/2)(4)), or (3/2, 6).

Brut [27]

Answer:

See the explanation.

Step-by-step explanation:

Cora is making a rectangular prism. She plans to have 8 inches if height. What will be the volume of the rectangular figure?

As the figure formed is a rectangular prism. we need to find the volume of  rectangular prism. Volume of prism will be:

Volume = Length · Width · Height

As she wants to have 8 inches of height, substitute it in the given equation:

Volume = 8(Length · Heights) inch³

I don’t understand #6 question
romanna [79]

Answer:

B. (10, 2000)

Step-by-step explanation:

5000 - 300t = 1400ft - 1200f

=> t = 10

10 => (5000 - 300t) = 2000

So the answer is B. (10, 2000)

Joanna set a goal to drink more water daily. The number of ounces of water she drank each of the last seven days is shown below.
hammer [34]

<u>Answer:</u>

The median amount of water is higher when the eighth day's amount is included in the data.

<u>Explanation:</u>

Given the ounces of water drank is 60, 58, 64, 64, 68, 50, 57

Arranging in ascending order: 50, 57, 58, 60, 64, 64, 68

Calculating the median of the above data

Median (when n is odd) = \left(\frac{n+1}{2}\right)^{t h} \text { term }

where n =7

Median = 4th term = 60

When the eight day is added,

Series will be: 50, 57, 58, 60, 64, 64, 68, 82

Median (when n is even) =       \frac{\left(\frac{n}{2}\right)^{t h} t e r m+\left(\frac{\pi}{2}+1\right)^{t h} t e r m}{2}

Median = \frac{60+64}{2}=62

So, here we can say that median has increased after adding 82 in the data
