(x,y) is a solution to an eqn when y = mx + c
A. 2(2)-1 = 3 <>-1
B. 2+3 = 5<>-1
C. 2-3 = -1 = y
so C has (2,-1) as a solution
Answer:
y = 4 sin( 0.5t - ) - 2
y = a sin ( 2t - ) + 2
Step-by-step explanation:
In the first question,
amplitude = 4
Period =
phase shift =
Vertical shift = -2
Angular velocity , w =
Here, w = = 0.5
The general equation of a wave is
y = a sin( wt + ∅ )
Putting above values in the equation,
y = 4 sin( 0.5t - ) - 2
In the second question,
Amplitude is not given so we will take it as a.
time period =
w = 2
Phase shift =
Vertical shift = 2
The equation is
y = a sin ( 2t - ) + 2
To find the ratio in simplest form, the unit hours must be converted into minutes. 1 hour is equal to 60 minutes so 2 hours is 120 minutes. The simplest form is then
The correct answer is 1/8.
It's either 53 or 152,064 not sure sorry if i'm wrong but pretty sure it's 53...
Answer:
C. 9.
Step-by-step explanati
3- (-3) +7 – 4 =
3 + 3 + 7 - 4 (- (- = + )
= 13- 4
= 9.
