Hi! Remember me?

Anyways let's get on with it

The scale factor determines how large a figure increases by multiplying the coordinates of every point of the figure by the scale factor ONLY when the point of dilation is at the origin

I am not sure of the point of dilation since it does not state it so I will try to see if it is a enlargment or reduction

I'm going to choose only one point since we can already determine enough information for the scale factor with one point. Let's try point S

S (1, 8)

S' (3, 4)

The entire figure clearly seems to have reduced, and using a negative scale factor will cause the new figure to be an upside down version of the original one like a reflection. The new square is clearly not upside down from the original or it would be below the x-axis The only other option of reduction is 1/2. Any fraction less than 1 and greater than 0 will reduce the size of the original figure.

Answer:

z^ {8/5}

Step-by-step explanation:

$(z^{\frac{-4}{3})^{\frac{-6}{5} } \\We\ know\ that\ a^{(b)^c} = a^{bc}\\\\Hence, \\\\{z^{\frac{-4}{3})^{\frac{-6}{5}}\\}={z^{\frac{-4}{3}*\frac{-6}{5}\\}\\=z^{\frac{24}{15}}\\=z^\frac{8}{5}$

If you know that 84 is 70% of the whole, explain how you can use proportional reasoning to determine the whole. Use the drop-dow

Akimi4 [234]

Answer: The value of whole is 120.

Step-by-step explanation:

Since we have given that

84 is 70% of the whole.

Let the whole be 'x'.

According to question, it becomes,

$84=\dfrac{70}{100}\times x\\\\84=0.7\times x\\\\\dfrac{84}{0.7}=x\\\\120=x$

So, we have use the proportion i.e. $\dfrac{84}{70\%}=\dfrac{84}{0.7}$ to determine the value of whole.

Hence, the value of whole is 120.

Hearts win. In a new card game, you start with a well-shuffled full deck and draw 3 cards without replacement. If you draw 3 hea

Afina-wow [57]

Answer: −1.409

Step-by-step explanation:

Probability of drawing 3 hearts: 13/52 * 12/51 * 11/50 = 0.013

Probability of drawing 3 black cards: 26/52 * 25/51 * 24/50 = 0.118

Probability of other draw: 1 - 0.013 - 0.118 = 0.869

0.013 * (50 - 5) = 0.585

0.118 * (25 - 5) = 2.353

0.869 * (0 - 5) = -4.347

Expected value: 0.585+ 2.353 - 4.347 = -1.409

Determine whether each of the following relations is a function

Pavlova-9 [17]

Thank you for posting your question here. The question seems to be unclear. A function is a relation in which each element of the domain is paired with exactly one element of the range. When x = 0, y = 1 and y = 6. So, this relation is not a function. SOLUTION: This is a function because no vertical line can be drawn so that it intersects the graph more than once.
