The displacement of a mass suspended on a spring is modeled by the
function y = 5sin( pi t) where y is measured in inches and t in seconds. the
amplitude, period, and frequency of the motion of the mass are given by
o
a. amplitude = 2, period = 2, and frequency = 2
o
b. amplitude = 5, period = 1, and frequency = 1
o
c. amplitude = 5, period = 2, and frequency = 1/2
d. amplitude = 5, period = 1/2 and frequency = 2

is this part of a question or something

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
