Look at my upload to see the graph, I couldn't see the choices, so I can't give you a definite answer. But the graph below is the correct one.
Hope that helped!
Answer:
<h3>44 ft</h3>
Step-by-step explanation:
The set up will give a right angled triangle where;
Base of the triangle = 90 ft (distance of the offshore from the base of the house)
theta = 26 degrees (angle of elevation)
Height of the house will be the opposite side = x
Using the TOA trig identity;
tan 26 = opp/hyp
tan 26 x/90
x = 90tan 26
x = 90(0.4877)
x = 43.89 ft
Hence the nearest height of the house is 44ft

Answer:
The function for the outside temperature is represented by , where t is measured in hours.
Step-by-step explanation:
Since outside temperature can be modelled as a sinusoidal function, the period is of 24 hours and amplitude of temperature and average temperature are, respectively:
Amplitude
Mean temperature
Given that average temperature occurs six hours after the lowest temperature is registered. The temperature function is expressed as:
Where:
- Mean temperature, measured in degrees.
- Amplitude, measured in degrees.
- Daily period, measured in hours.
- Time, measured in hours. (where t = 0 corresponds with 5 AM).
If , and , the resulting function for the outside temperature is:

</span><span> =-3(-4)^2 (2) + 4(-4)
=-96-16
=-112</span>
