Answer:

Angle measures, size, shape, position of center of rotation.

Step-by-step explanation:

Rotation is a rigid motion, meaning the angle measures, size, and shape are preserved. Also, since we are rotating around the center, the center would stay the same. So the answer is angle measures, size, shape, position of center of rotation.

Shannon rolls a number cube and then chooses a card from set of cards numbered 1 through 5. What is the proability that she will
Anuta_ua [19.1K]
Half of the numbers on the cube are even, so there's a 1/2 chance that that number is even.  3/5 of the numbers on the cards, however, are odd.  The chance that both of these occur is 3/5*1/2=3/10.

write the product of the expression 5^4 * 5^-7 using a positive exponent, then write the product using a negative exponent
pav-90 [236]

Answer with positive exponent = \left(\frac{1}{5}\right)^3 or  \frac{1}{5^3}

Answer with negative exponent = 5^{-3}

===========================================================

Explanation:

The rule we use is

a^b*a^c = a^{b+c}

If we multiply two exponential expressions with the same base, then we add the exponents.

The base for each is 5. The exponents 4 and -7 add to -3.

This means

5^4*5^{-7} = 5^{4+(-7)} = 5^{-3}

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.

So, 5^{-3} = \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} = \frac{1}{5^3}
