The equation can be used to model the height as a function is where t is time, the second option is correct.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know the general equation for the cosine function:
Where A is the amplitude
We have a wall clock that varies from 9 feet to 10 feet.
The value of 'A' is given by:
b is the cycle speed, we know:
(T is period)
The value of d is given by:
d = 9.5
The equation can be modeled:
(c =0 and y =h)
Thus, the equation is

Answer:
Step-by-step explanation:
So 8/12 + 7/8 needs to be greater than 1 foot? It is.
8/12 = 2/3
7/8 + 2/3 =
7/8 = 3*7 / 8*3 = 21 / 24
2/3 = 8*2 /8*3 = 16 / 24
Now add them
21 / 24 + 16/24 = 37/24 which is way more than 1 foot.
37/24 = 1 13/24

Answer: 29.3
Step-by-step explanation:
Abby's average after taking 31 quizzes is 76.
Total test scores= 31 × 76 = 2356
After Abby's teacher drops her 3 lowest test scores, her average increases to 81. This means that (31-3)= 28 test scores were used.
Total scores = 28 × 81 = 2268
Sum of Abby's three lowest score
= 2356 - 2268
= 88
Average of the three scores will now be 88 divided by 3
= 88/3
= 29.3
The average is 29.3
