Answer:
458.92
Step-by-step explanation:
77%×596=458.92
Answer: 49π or 153.86
Explanation: To find the R, do 14 divide by 2 because since you're not multiplying pi with it. The circumference formula is 2πr
14 / 2 = 7
7 = Radius
Area of a circle is : πr^2
π(7^2)
π49

Answer:
C) 2BC = XY
Step-by-step explanation:
A) ZX || XY
No, sides of the triangle, not same size
B) BC || AB
No, sides of triangle
C) 2BC = XY
Yes, as BC║XY and YA= AX
D) YZ = AC
No, YZ║AC but is twice a length
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
-8 * -8 * -8 * -8 * -8 * -8 * -8
(-8)^7
