A pendulum is swinging next to a wall. The distance D(t) (in cm) between the bob of the pendulum and the wall as a function of time t (in
seconds) can be modeled by a sinusoidal expression of the form a • sin(b. t) + d.
At t = 0, when the pendulum is exactly in the middle of its swing, the bob is 5 cm away from the wall. The
bob reaches the closest point to the wall, which is 3 cm from the wall, 1 second later.
Find D(t).
t should be in radians.
D(t)

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
