Answer:
Option (1)
Step-by-step explanation:
Equation of the given wave function,
f(x) = acos(bx)
Here, a = amplitude of the wave
Period of the wave =
From the graph attached,
Amplitude =
=
= 4
Period of the wave = π - 0
= π
From the formula of the period,
Period =
b = 2
Therefore, a = 4 and b = 2.
Option (1) will be the answer.
Answer:
First one
Step-by-step explanation:
5sin(3pix)+8=4
5sin(3pix) = -4
sin(3pi x) = -0.8
Basic angle: sin^-1(0.8) = 0.927295218
3pi x = pi+0.927295218, 2pi-0.927295218
3pi x = 4.068887872, 5.355890089, 4.068887872 + 2pi, 5.355890089 + 2pi, 4.068887872 + 4pi, 5.355890089 + 4pi,
x = above values/3pi
x = 0.43217, 0.568, 1.0984, 1.235, 1.765, 1.9016
Answer:
i'm pretty sure that it's y=-2x+1
Step-by-step explanation:
first we solve for the slope of the line:
we have the points (-1,3) and (3,-5). So we write an equation like so:
<u>3 - -5</u>
-1 - 3
3/-1 - -5/3. solving that, you get 8/-4, and 8 divided by -4 is -2, so thats our slope.
now all we've got to do is get the y intercept. the way i found it was i graphed the line, put a dot on the points that we have ( (-1,3) and (3,-5) ) and you <em>should</em>
get 1 as the point on the y axis. again, i myself am not a pro or anything so if its not the correct answer i am so sorry. <3
