Answer:
V=3053.6
Step-by-step explanation:
Answer:
1760 Hz
Explanation:
The equation for the displacement has the following general formula:
d = A sin(wt)
where:
A is the amplitude
w is the angular frequency
the given equation is:
d = 0.6 sin(3520πt)
We can note that:
w = 3520 π rad/sec
Now,
w = 2πf where f is the frequency
Therefore:
3520π = 2π*frequency
This means that:
frequency = 1760 Hz
Hope this helps :)
Answer:
V = 30 cubic inches
Step-by-step explanation:
Given:
height (h) = 10 in.
Base area (B) = 9 in.²
Required:
Volume of the pyramid
Solution:
Formula for finding volume of triangular pyramid = ⅓(B)(h)
Plug in the values
V = ⅓(9)(10)
V = (3)(10)
V = 30 cubic inches
Life expectancy of dollar bill = d
life expectancy of coin = c
d = 1/20 c
substitute value in for c (30)
d = 1/20 * 30
d = 30/20
d = 1.5
life expectancy of a dollar bill = 1.5 years
Yes, it is a true statement, since the absolute value of any negative number is its opposite -- the positive version of the number.
