Answer:
False
Step-by-step explanation:
You can't add two different variables together
Step-by-step explanation:
the area of a parallelogram is
baseline × height
the height here is 4 cm.
the baseline is 12 - 2 = 10 cm
the area of the parallelogram is then
10 × 4 = 40 cm²
Answer:
y = 6cos(π/2)t
Step-by-step explanation:
Given in the question that,
in a simple harmonic motion in which
at t=0 the amplitude is 6 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.
And,
the period is given as 4 sec
We know that model equation of simple harmonic motion is
<h3>y = a. cosb(t + c) + d</h3>
here,
a is amplitude
c is Horizontal shift or phase shift
d is Vertical shift
<h3>Step1</h3><h3>Find b</h3>
Period = 2 π / b
4 = 2π / b
b = 2π/4
b = 1π/2
<h3>Step2</h3><h3>Find shifts</h3>
Horizontal and vertical shifts are 0.
So, c = 0 and d = 0
<h3>Step3</h3><h3>Plug those values in the above in the equation</h3>
y = 6cos π/2 (t + 0) + 0
y = 6cos(π/2)t
Answer:
A=1/12
Step-by-step explanation:
3/4-2/3=3*3/4*3-2*4/3*4=9/12-8/12=1/12
Answer:
B
Step-by-step explanation:
Distributive property is when you use the number on the outside of the parenthesis to multiply to the inside. So, 36+9=3(12+3), in order to solve it on the parenthesis side you would take 3 and multiply it by 12, giving you 36. Then, you would take 3 and multiply it to the other 3 which gives you 9.
