Step-by-step explanation:
The function can be ...
D(t) = A +Bcos(C(t-p))
where A is the average depth (55+12)/2 = 33.5 cm,
B is the peak deviation from average, 55 -33.5 = 21.5 cm,
C is the horizontal scale factor (2π/T) = (2π/3) for a period (T) of 3 seconds,
and p is the phase offset, given as 1.1 seconds.
The function is ...
D(t) = 33.5 +21.5cos(2π/3·(t -1.1))
Answer:
Step-by-step explanation:
To find the x-intercept, substitute 0 for y and solve for x:
Divide both sides by 2:
Add 7 to both sides to isolate x:
The x-intercept for 
is 7 at point 
.
Remove parentheses:
Subtract 2 from both sides:
The x-intercept for 
is -2 at point 
.
Finito.
Work: x/175=12%/100
multiply 175 by 2 and then you divide it by 100

Answer:
1. Figure C
2. Figure C
3. Figure B
Step-by-step explanation:
The answer is C) $4,187
First you need to turn the 6% into a decimal 6%--> .06
Now you need to multiply .06 to $3,850
$3,850x.06= $237 <---Sales Tax
Now just add thesales tax to the orignal price
$3,850+$237= $4,187
