Answer:
The correct option is;
d(t) = 6·cos(π/3·t) + 28
Step-by-step explanation:
The general form of a cosine function is given as follows;
y = A·cos(B·x - C) + D
Where;
A = The amplitude = The distance from the peak to the midline = 1/2×(Maximum - minimum)
The amplitude = 1/2 × (34 - 22) = 6 inches
B = 2·π/P = 2·π/6 = π/3
P = The period = 6 seconds
C/B = The phase shift
D = The midline = Minimum + Amplitude = 22 + 6 = 28 inches
x = The independent variable
Therefore, to model the function of the wave can be given as follows;
d(t) = 6·cos(π/3·t) + 28
Answer:
4.9
Step-by-step explanation:
use congruent triangles. we has 7 /10 = x/ 7

So there are 64 books (lol, minecraft) 64 divided by 5= 12 remainder 4 So there are 12 complete stacks of 5.
Defend:
There are 64 books and each stack has 5 books. 64 divided by 5 equals 12 with a remainder of 4. Since each stack must have 5 books there are 12 complete stacks.
