Answer:
Step-by-step explanation:
<em>m∠D</em> = 90° - 51° = <em>39°</em>
sin E = 
⇒ DE = DF × sin E
<em>DE</em> = 18 sin51° ≈ <em>14.0 ft.</em>
cos E = 
⇒ EF = DF × cos E
<em>EF</em> = 18 × cos51° ≈ <em>11.3 ft.</em>

Answer: 1.6 lawns a week
Step-by-step explanation:
Carlt mowed 2 more lawns than Rocco every week for 5 weeks.
This means that the number of lawns he mowed more than Rocco is:
= 2 * 5
= 10 lawns
If Carlt mowed 18 lawns in those 5 weeks then Rocco mowed:
= 18 - 10
= 8 lawns
Lawns mowed per week by Rocco:
= 8/5
= 1.6 lawns a week

Answer: A,D,E
Step-by-step explanation:
Let’s walk through this with every possible option.
A: The input is the x axis, and since there is no x value that is used twice, this is true.
B: No. It is higher at 30 seconds than at 31 seconds, meaning that as time increases, the height does not always increase.
C: No. You cannot determine the time based on height. For example, at a height of 40, you don’t know if it’s at 20 or 40 seconds.
D: Yes. Assuming the picture on the left corresponds, it is a circle. Once you get to the original point, which is at 60 seconds, it will start all over again.
E: The time is the x axis, and the title is height, so yes.
