Which figure could be the result of dilating this rectangle with a scale factor between 0 and 1? On a coordinate plane, a rectan

Leviafan [203]

Answer:

(a) On a coordinate plane, a rectangle has points (0, 0), (0, 1), (2, 0), (2, 1)

Step-by-step explanation:

Every point coordinate of the dilated figure will be smaller by the same factor.

Looking at the original (0, 3) coordinate, we find that possible answer choices include ...

A (0, 1) has a scale factor of 1/3

B (0, 4) has a scale factor greater than 1

C (0, 1) has a scale factor of 1/3

D (0, 2) has a scale factor of 2/3

Looking at the rest of the points in the answer selections, we find that the scale factors in choices C and D are not consistent from one point to another (or even within the same point). Those choices must be rejected.

In selection A, the image points are listed out of order, tending to confuse the issue. However, A is the correct choice.

Which property was used to simplify the expression?<br><br> (3z)^2 = 3^2z^2 = 9z^2

svet-max [94.6K]

One of the product rules for exponents was used.
$(ab)^{c}=a^{c}b^{c}$

Or, you can consider that the definition of an exponent and the associative and commutative properties of multiplication were used.
$(3z)^{2}\\=(3z)(3z)\\=3\cdot 3\cdot z\cdot z\\=3^{2}z^{2}\\=9z^{2}$

A teacher asks a student to find 54 of a number. Instead, the student finds 45 of the number. Her answer is 36 less than the cor

Marrrta [24]

45 of a number refers to 180, and 54 refers to 216. So 100 of a number is 400 and 1 of a number is 4. If 54x - 45x = 36, just plug in 4 and double check: 54(4) - 45(4) = 36 or 216 - 180 = 36, which is true.
