Formula: V = PI x r^2 x H

Volume = 3.14 x 4^2 x 10

Volume = 3.14 x 16 x 10

Volume = 3.14 x 160

Volume = 160π or 502.4 units^3

To find the volume of a cylinder, we use the formula represented below.

Volume = $\pi$ $r^{2}$ h

Notice that our cylinder has a radius of 4 and a height of 16, so we can plug these numbers into our formula.

Problem A. Consider the following initial value problem for a damped driven linear oscillator: m 2 + b** + kx} = f sin(St); x(0)

skad [1K]

Answer:

a = L

b = MT^(-1)

c = LT^(-1)

k = MT^(-2)

f = MLT^(-2)

S = T^(-1)

Step-by-step explanation:

x (0) = a

x is denoted by displacement in vibration analysis hence attains units of x.

Hence, a = L

b is the damping coefficient:

$b = \frac{F}{\frac{dx}{dt} } \\= MLT^(-2) / LT^(-1)\\= MT^(-1)$

x'(0) = c

dx/dt = velocity hence c attains the units of velocity

c = LT^(-1)

Coefficient k is the stiffness:

$k = \frac{F}{x} = \frac{MLT^(-2)}{L} = MT^(-2)$

Coefficient f is the magnitude of the exciting force

$F = m*acceleration = MLT^(-2)$

Coefficient S is the angular frequency

angular frequency is displacement in radians per seconds; hence,

S = T^(-1)

Jay currently has a balance of $2,375 on her credit card. If she must make a minimum monthly payment of 5.8% of her total balanc

Papessa [141]

Answer:

$137.75

Step-by-step explanation:

question is 'what is 5.8% of 2375'

'what' means assign a variable

'is' means an equal sign

'of' means to multiply

p = .058 x 2375

p = 137.75

*You could do the following: p = 5.8 x 2375 and get 13775 but you have to remember to move the decimal point two places to the left

Barbara claims that her horse can do simple addition problems. She showed her horse eight different cards with simple addition p

Arturiano [62]

Answer:

Barbara's horse can add

Step-by-step explanation:

To test if the horse could add, Eric he tried to calculate experimentally the probability that the horse had guessed the 8 answers.

If we call "trial" the action of throwing 8 coins and count the number of tails obtained, then eric made 53 trials.

During each trial, 8 events could have occurred:

Get 1, 2, 3, 4, 5, 6, 7 or 8 tails.

The plot of points obtained by Eric shows the frequency in which each of these 8 events occurred during the 53 trials.

The fact that the point diagram shows only one point on event 8, means that it occurred only once during the 53 trials, and compared to the other 7 events, this was the one with a lower frequency (the one that obtained the the highest frequency was the 4-tailed one, with 11 points).

This means that it is very unlikely to get 8 queues when casting 8 coins.

Therefore it also means that it is unlikely that Barbara's horse has guessed the 8 answers.

So, curiously, Barbara's horse maybe knows how to add
