Answer:
tanC = 3/4
Step-by-step explanation:
by Pythagoras theorem first find the line DE =
+
=
-> DE=27
then we know that tanθ=opposite/adjacent
so, 27/36 =tanC
simplified: tanC = 3/4
Answer:
B. d = 4 cos(π/3 t)
Step-by-step explanation:
As at t=0 the amplitude is 4 cm, so the simple harmonic motion will be in cosine form. As in case of sine function, the value of function at t=0 is 0.
sin 0=0
We know that,
y = a. cosb(t + c) + d
Period = 2 π / b
Horizontal shift or phase shift is c,
Amplitude is a,
Vertical shift is d.
As in this case the amplitude is given to be 4, hence = 4
Also the period is given as 6.
That is, 2π/b = 6
b = 2π/6 = π/3
Here horizontal and vertical shifts are 0.
That is c = 0 and d = 0
Plug those values in the above form, we get
y = 4.cos π/3 (t + 0) + 0
y = 4 cos (π/3)t
Answer: B. d = 4 cos(π/3 t)
Hope this will helpful.
Thank you.
Answer:
You put in meaningless answers for other people so you don’t deserve an answer. Yeah, typing random letters isn’t really helpful. Shocking isn’t it?
Step-by-step explanation:
Fastest method for calculating what percent of 900 is 18
Assume the unknown value is 'Y', and 18 of 900 can be written as:
Y =
18
900
By multiplying both numerator and denominator by 100 we will get:
Y =
18
900
x
100
100
=
2
100
Y = 2%
Answer: 2 percent of 900 is 18
If you want to use a calculator, simply enter 18÷900x100 and you will get your answer which is 2
