Step-by-step explanation:

The volume of the rectangular fish tank is:

V = l x w x h = 60 cm x 15 cm x 34 cm = 30,600 cm³

Since the tank is 1/3 full, the volume of water in the tank is:

V_water = (1/3) x V = (1/3) x 30,600 cm³ = 10,200 cm³

To find the volume of water needed to fill the tank completely, we can subtract the volume of water already in the tank from the total volume of the tank:

V_needed = V - V_water = 30,600 cm³ - 10,200 cm³ = 20,400 cm³

Therefore, 20,400 cm³ of water is needed to fill the tank completely.

The scale of the map = 682.5.

We kept a safe distance and followed them. She perceives a separation between her and her brother that wasn't there before. Although they were previously close friends, there was now a great deal of gap between them.

We must calculate the ratio of the distance shown on the map to the real distance between the cities in order to ascertain the scale of the map.

We are aware that there are 210 miles separating the two cities. Let x represent the precise location of this distance on the map. From that, we may establish the ratio:

Actual distance / Map Distance = 210 / x

The distance on the map is indicated as 3 1/4 inches, which is also known as 13/4 inches. When we enter this into the percentage, we obtain:

Actual distance divided by (13/4) = 210 / x

We can cross-multiply and simplify to find x's value:

Actual distance: 682.5 = x * 210 x = 3.25 when 210 * (13/4) Equals x.

Consequently, 3.25 inches on the map represent the actual distance between the cities. We can write: To determine the map's scale:

Actual distance divided by 1 inch on the chart equals 210 miles.

When we replace the values we discovered earlier, we obtain:

1 / 210 = 3.25 / scale

If we solve for the scale, we obtain:

scale = 682.5.

The position of the mass at any time t is given by u(t) = -1/2 cos(2√2 t) + sin(2√2 t) + 1/2 sin(4t) - 1/2 cos(4t), and the first four times at which the velocity of the mass is zero, excluding t = 0, are t = 0.0567, 0.283, 0.510, and 0.736.

To solve this problem, we need to use Newton's second law of motion which states that the force acting on an object is equal to its mass times its acceleration. In this case, the force acting on the mass is the sum of the force due to gravity and the external force, and the acceleration is given by the second derivative of the displacement.

Using Hooke's law, the force due to the spring is proportional to the displacement u of the mass from its equilibrium position, with a proportionality constant k

F_spring = -k u

where k is the spring constant. Since the mass is pulled down 6 in. from its equilibrium position, the initial displacement is u(0) = -0.5 ft. The spring stretches 24 in. under a weight of 8 lb, so the spring constant is

k = F_spring / u = (8 lb) / (2 ft) = 4 lb/ft

The force due to gravity is

F_gravity = m g

where m is the mass of the object and g is the acceleration due to gravity. The mass is given in pounds, so we need to convert it to slugs:

m = 8 lb / (32.2 ft/s^2) = 0.248 slugs

Thus, the force due to gravity is

F_gravity = (0.248 slugs) (32 ft/s^2) = 7.94 lb

The equation of motion for the displacement u(t) is

m u''(t) = F_gravity + F_spring + F_external

where F_external = 4 sin 4t lb is the external force. Substituting the expressions for these forces and dividing by m, we get

u''(t) + 8 u(t) = 2 sin 4t

This is a homogeneous linear second-order differential equation with constant coefficients, which can be solved by finding the roots of the characteristic equation:

r^2 + 8 = 0

The roots are r = ±2i√2. The general solution of the differential equation is then

u(t) = c1 cos(2√2 t) + c2 sin(2√2 t) + u_p(t)

where u_p(t) is a particular solution of the nonhomogeneous equation. Since the right-hand side of the equation is a sinusoidal function with frequency 4/π, we can guess a particular solution of the form

u_p(t) = A sin(4t) + B cos(4t)

Substituting this into the equation and equating coefficients, we get

16 A - 16 B + 8 A = 2, or A = 1/2

-16 A - 16 B + 8 B = 0, or B = -1/2

Therefore, the particular solution is

u_p(t) = 1/2 sin(4t) - 1/2 cos(4t)

The general solution is then

u(t) = c1 cos(2√2 t) + c2 sin(2√2 t) + 1/2 sin(4t) - 1/2 cos(4t)

We can use the initial conditions u(0) = -0.5 and u'(0) = 0 to determine the values of c1 and c2

u(0) = c1 + 1/2 = -0.5, or c1 = -1/2

u'(0) = -2√2 c1 + 2√2 c2 - 2 = 0, or c2 = 1

The values for a and b such that f(t) = a + logb(t) are,

a = log(1/log(49))

b = 49

Therefor

We can start by simplifying the expression for f(t)

f(t) = log49(t7)

f(t) = log(t7)/log(49) [Using the change of base formula]

Now we can rewrite f(t) as:

f(t) = log(t)/log(b) + a [Using the logarithmic properties log(ab) = log(a) + log(b)]

Comparing this expression with f(t) = a + logb(t), we can see that:

a = log(1/log(49)) [since log(b) = 1/log(49)]

b = t

Therefore, we have

f(t) = log(t7)/log(49) = log(t)/log(b) + log(1/log(49))

= log(t)/log(49) + log(1/log(49))

= log(1/log(49)) + log(t)/log(49)

So, a = log(1/log(49)) and b = 49.

What are the zeros of the function f(x)= 240x -2x^2

Step-by-step explanation:

To find the zeros of the function f(x) = 240x - 2x^2, we need to set f(x) equal to zero and solve for x:

240x - 2x^2 = 0

We can factor out 2x from the left side:

2x(120 - x) = 0

So either 2x = 0 or 120 - x = 0. Solving for x in each case gives:

2x = 0 => x = 0

120 - x = 0 => x = 120

Therefore, the zeros of the function are x = 0 and x = 120.

9x = 18

Divide both sides by 9:

x = 2

Therefore, the solution to the equation is x = 2.

8x - 4 = 28

Add 4 to both sides:

8x = 32

Divide both sides by 8:

x = 4

Therefore, the solution to the equation is x = 4.

Add 18 to both sides:

-x = 75

Multiply both sides by -1:

x = -75

Therefore, the solution to the equation is x = -75.

-4 - 8x = 8

Add 4 to both sides:

-8x = 12

Divide both sides by -8:

x = -1.5

Therefore, the solution to the equation is x = -1.5.

3x + 0.7 = 4

Subtract 0.7 from both sides:

3x = 3.3

Divide both sides by 3:

x = 1.1

Answer:

Step-by-step explanation:

Let B be the event that the selected coin is biased, and F be the event that the selected coin is fair. Let H be the event that the coin toss shows a head.

We want to find P(B|H), the probability that the selected coin is biased given that the coin toss shows a head. By Bayes' theorem, we have:

P(B|H) = P(H|B) * P(B) / P(H)

We know that P(H|B) = 1/4 (since the biased coin has a probability of 1/4 of showing a head), and that P(B) = 1/2 (since there are two coins, one of which is biased).

To find P(H), we can use the law of total probability:

P(H) = P(H|B) * P(B) + P(H|F) * P(F)

P(H) = (1/4) * (1/2) + (1/2) * (1/2)

P(H) = 3/8

Putting it all together:

P(B|H) = P(H|B) * P(B) / P(H)

P(B|H) = (1/4) * (1/2) / (3/8)

P(B|H) = 1/3

Therefore, the probability that the selected coin is biased given that the coin toss shows a head is 1/3.
