Answer:
The temperature of metal after five years = -18.96875
Step-by-step explanation:
Given : Function
where x is measured in hours
Another function is added h(x)=-x-3
therefore, the resultant function f(x)=h(x)+c(x)
For x=5
Therefore, The temperature of metal after five years = -18.96875
The height of the kite will be 6.6 ft rounded to the nearest tenth.
<u><em>Explanation</em></u>
According to the below diagram, AB is the height of the kite and AC is the 12 ft line attached to it.
The line is pulled taut and casts a 10 ft shadow. That means BC = 10 ft
Now, in right angle triangle ABC, using <u>Pythagorean theorem</u>....
So, the height of the kite will be 6.6 ft rounded to the nearest tenth.
