Answer:
13.7 cm
Step-by-step explanation:
- there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
- since we know that 360°-260.4°=99.6°
- The angle measure of arc AD is 99.6°
Now that we covered that, we can use the arc length formula in order to find the length of arc AD.
- arc length = 2πr(Θ/360°)
- 2π(7.9)(99.6°/360°) = 13.7329
- rounded to the nearest tenth = 13.7
Answer:
CD
Step-by-step explanation:
if B comes after A and you put them together that makes AB so do the same for CD CD is the answer
A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.
B) Find general solution by separating variables and integrating
:
C) Initial condition is t=0, T = 87
D) Total time elapsed is 10 minutes, new temperature is 84
solve for alpha
E) Temperature function is:
solving for t
Plug in T = 98.6
This is approximately 32 minutes before he arrived or about 1:20 AM
