Question 1
What trig function would we use the find this angle of elevation?
Sine
What is the common difference and u1.
d = 30 u1 = 85

Find the coffee's temperature 16 minutes after it started to cool.
54.6 degrees C.
Find the angle of elevation from the ship to Kacheena.
10.5 Degrees
un = u1 + (n-1) *d
Sn = N/2(u1 + un)
What is one of 2 ways that you can find the maximum height?
plug into calculator and find the maximum using the graph
or
-b/2a (Vertex formula)
Write down the alternative hypothesis.
An adult's favorite breakfast berry and their income are dependent.
Write down the equation of the horizontal asymptote.
y = 23
Either Pythagorean theorem or Law of sines

Plug the table into Matrix
Then, STAT-->Tests-->C: x^2 Test
Write down the room temperature.
23 degrees C.
What is the distance to the ship?
1180 m
Find the total number of trees planted in the 1st 15 months
4425/4430 trees
What is the value of t when the tip of the javelin is at its maximum?
1.5 seconds
x^2 = 2.27
Tell me how would I solve for k in this situation
50 = 71e-0.0514(k) +23
use ln to solve for k
Write down the answer from part c.

295 or 295.33 trees
What is the value of t when the tip of the javelin hits the ground?
3.16 seconds
Write down Sergio's conclusion to the test in context. Justify your answer.
2.27 < 7.78 or 0.687 > 0.10
Fail to Reject/Accept the null hypothesis based on the info above
So then what is the value of k.
