60 miles because (20mph)((3hrs) = 60
Has 16 cups of water that is half full.
16/2 = 8
Watering can then has 8 cups of water in it.
This number needs to be divided by 15 plants.
The answer is 8/15 of a cup of water per plant which is also 0.53 cups per plant.
Given:
The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).
To find:
The vertices for
.
Solution:
The rule
represents refection of polygon QRST across the x-axis.
If a figure is reflected across the x-axis, then

Using this rule, we get




Therefore, the vertices for
are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).
The given expression 2^8 * 8^2 * 4^-4 can be written in the exponential form 2^n as 2^6.
<h3>What are exponential forms?</h3>
The exponential form is a more convenient way to write repetitive multiplication of the same integer by using the base and its exponents.
<u>For example:</u>
If we have a*a*a*a, it can be written in exponential form as:
=a^4
where
- a is the base, and
- 4 is the power.
The power in this format reflects the number of times we multiply the base by itself. The exponent is also known as the index or power.
From the information given:
We can write 2^8 * 8^2 * 4^-4 in form of 2^n as follows:




Therefore, we can conclude that by using the exponential form, the given expression 2^8 * 8^2 * 4^-4 in the form 2^n is 2^6.
