At time t is greater than or equal to zero, a cube has volume V(t) and edges of length x(t). If the volume of the cube decreases at a rate proportional to its surface area, which of the following differential equations could describe the rate at which the volume of the cube decreases?
A) dV/dt=-1.2x^2
B) dV/dt=-1.2x^3
C) dV/dt=-1.2x^2(t)
D) dV/dt=-1.2t^2
E) fav/dt=-1.2V^2
Answers
Answer:
C
Step-by-step explanation:
V(t) = [x(t)]³
A(t) = 6[x(t)]²
dV/dt = k × 6[x(t)]²
Where k < 0
From the options,
taking k = -0.2
dV/dt = -1.2[x(t)]²
The correct answer is A) dV/dt=-1.2x^2, which represents a rate of volume decrease directly proportional to the cube's surface area.
Explanation:The question involves finding a differential equation that describes the rate at which the volume of a cube decreases when the rate is proportional to the cube's surface area. Since the surface area of a cube is 6x(t)^2 and the volume is x(t)^3, the rate of decrease in volume, dV/dt, is proportional to the surface area.
The correct differential equation would show this relationship by having the change in volume be proportional to the square of the edge length, so dV/dt = -kx^2 for some constant k, which means the valid option is A) dV/dt=-1.2x^2.

Answers
The point on a number line that is closest to Pi (π), which is approximately 3.14, would be the point representing either 3 or 4 as they are the closest whole numbers. However, a point representing 3.14 or a closer approximation would be even nearer.
Explanation:The question is asking to identify which point on a number line is closest to Pi (π), a mathematical constant that approximately equals 3.14. On a number line, you can visualize numbers as points. As Pi is 3.14 approximately, the closest point to Pi on a number line would naturally be the point that represents 3 or the point representing 4, as these are the two closest whole numbers to 3.14. However, if there's a point representing the value 3.14, or even closer approximation like 3.141, it would be even closer to Pi than the points representing 3 or 4.

What is the magnetic force on a proton that is moving at 2.5 x 10 m/s to the
left through a magnetic field that is 3.4 T and pointing toward you? The
charge on a proton is 1.6 10-19 c. Use F-qvx B sin(o).
Answers
Answer:C. 1.4 10-11 N up
step-by-step explanation:
Explanation:
The magnetic force, F on a charge q moving with velocity v in a magnetic field B at an angle θ is given by:
F = q v B sin θ
Charge of proton, q = 1.6 × 10⁻¹⁹ C
Strength of magnetic field, B = 3.4 T pointing outwards
velocity of the proton, v = 2.5 × 10⁷ m/s towards left
Magnetic force is given by:
F = 1.6 × 10⁻¹⁹ C× 2.5 × 10⁷ m/s ×3.4 T× sin 90 = 13.6 × 10⁻¹² N = 1.4 × 10⁻¹¹ N up
The direction of the force is given by Lorentz Right hand rule. The fingers point magnetic field, the thumb points towards velocity, then the force on the proton is given by the direction perpendicular to the palm.
The magnetic field acts outwards with velocity of the proton towards left. The force would act perpendicular to the two -upwards.
The magnetic force on the proton, moving to the left at 2.5 x [tex]10^6[/tex] m/s in a 3.4 Tesla magnetic field directed toward you, is approximately 1.36 x [tex]10^{-12}[/tex] Newtons.
To calculate the magnetic force acting on the proton in this scenario, we'll use the formula F = q × v × B × sin(θ), where:
F is the magnetic force,
q is the charge of the proton (1.6 x [tex]10^{-19}[/tex] C),
v is the velocity of the proton (2.5 x [tex]10^6[/tex] m/s),
B is the magnetic field strength (3.4 Tesla), and
θ is the angle between the proton's velocity vector and the direction of the magnetic field.
In this case, since the proton is moving to the left and the magnetic field is directed toward you, the angle θ is 90 degrees because they are perpendicular to each other.
Now, plug the values into the formula:
F = (1.6 x C) × (2.5 x [tex]10^6[/tex] m/s) × (3.4 Tesla) × sin(90°)
sin(90°) is equal to 1, so:
F = (1.6 x [tex]10^{-19}[/tex] C) × (2.5 x [tex]10^6[/tex] m/s) × (3.4 Tesla) × 1
F ≈ 1.36 x [tex]10^{-12}[/tex] N
So, the magnetic force acting on the proton is approximately 1.36 x [tex]10^{-12}[/tex] Newtons. This force causes the proton to experience a curved path due to the interaction between its velocity and the magnetic field.

It says that there are more than 10 counters in each bag.
So 2 bags is the most liable option.
There are 2 bags and 19 counters in each bag.
Answer:
2 bags, 19 counters.
Step-by-step explanation:
This question is looking for factors of 38 with counters being a factor greater ten and the number of bags being the factor that multiplies the counters to get 38. First, find the factors of 38.
1 x 38 = 38
2 x 19 = 38
Since the problem says bags with an s, we can know that there has to be more than one bag. That leaves us with 2 x 19.
Bus A and Bus B leave the bus depot at 8 am.
Bus A takes 25 minutes to do its route and bus B takes 35 minutes to complete its route.
At what time are they both back at the bus depot together?
Give your answer as a 12-hour clock time.
Answers
Answer: 10:55
Step-by-step explanation:
Taking statement at face value and the simplest scenario that commencing from 08:00am the buses take a route from depot that returns bus A to depot at 25min intervals while Bus B returns at 35min intervals.
The time the buses will be back at the depot simultaneously will be when:
N(a) * 25mins = N(b) * 35mins
Therefore, when N(b) * 35 is divisible by 25 where N(a) and N(b) are integers.
Multiples of 25 (Bus A) = 25, 50, 75, 100, 125, 150, 175, 200 etc
Multiples of 35 (Bus B) = 35, 70, 105, 140, 175, 210, 245 etc
This shows that after 7 circuits by BUS A and 5 circuits by Bus B, there will be an equal number which is 175 minutes.
So both buses are next at Depot together after 175minutes (2hr 55min) on the clock that is
at 08:00 + 2:55 = 10:55

The student will keep the slip of paper. The number of slips of paper in the bag with each continent name is shown below. Africa - 6 Asia - 8 Australia - 4 Europe - 6 What is the probability that a student in Mr. Woosley’s class will not be assigned a project on Australia?
Answers
The probability that a student will not be assigned a project on Australia is 20/24, which simplifies to 5/6.
The probability that a student in Mr. Woosley's class will not be assigned a project on Australia can be found by subtracting the probability of being assigned Australia from 1. There are a total of 24 slips of paper representing continents, and 4 of these are Australia. Therefore, there are 24 - 4 = 20 slips that are not Australia.
The probability, P(NOT Australia), is calculated as follows
Calculate the total number of slips: 6 (Africa) + 8 (Asia) + 4 (Australia) + 6 (Europe) = 24.
Determine the number of slips that are not Australia: 24 - 4 (Australia) = 20.
Find the probability: P(NOT Australia) = Number of non-Australia slips / Total number of slips = 20 / 24.
Therefore, the probability that a student will not be assigned a project on Australia is 20/24 or 5/6 when simplified.

Answers
Final answer:
The quadratic equation x²-5x-31=5 is solved by factoring to (x - 9)(x + 4) = 0, giving the solutions x = 9 and x = -4.
Explanation:
To solve the quadratic equation x²-5x-31=5 by factoring, we first move all terms to one side to get it into standard form:
x² - 5x - 36 = 0
Next, we look for two numbers that multiply to -36 and add up to -5. These numbers are -9 and 4. So, we can write:
(x - 9)(x + 4) = 0
Now, we have two possible solutions for x:
x - 9 = 0, which gives us x = 9x + 4 = 0, which gives us x = -4Therefore, the solutions to the equation are x = 9 and x = -4.

D.25.12 cubic units
Answers
The volume of the cone, calculated using the given slant length and diameter, is approximately 18.84 cubic units, therefore the correct answer is B. 18.84 cubic units.
Explanation:The subject of this question is the volume of a cone. In order to calculate the volume of a cone, you need to use the formula: V = 1/3πr²h. However, in this case, you are given the slant length and the diameter. First, we need to find the radius (r) and the height (h) of the cone. The radius would be half the diameter, so r = 4/2 = 2. Then, from the given slant length (s) and radius (r), we can find the height by using Pythagoras' theorem: h = sqrt(s² - r²) = sqrt(5² - 2²) = sqrt(21). Now we can substitute r and h into the volume formula: V = 1/3*3.14*2²*sqrt(21) which is approximately 18.84 cubic units. So the answer is option B.18.84 cubic units.

1). Sin(0) = cos (28)
2). Cos(y) = sin (0)
Answers
Answer:
1.)angle 0 = 62 degrees,
2.) angle 0 = 90 - y degrees.
Step-by-step explanation:
1). Sin(0) = cos (28)
angle 0 would be arcsin (cos (28)) = 62 degrees.
2). Cos(y) = sin (0)
angle 0 = arcsin ( cos (y) ) = 90 - y
To solve the equations involving trigonometric functions Sin(0) = cos(28) and Cos(y) = sin(0), use co-function identities to find 0 equals 62 degrees or (90° - 28°), and y could be 28 degrees or (360° - 28°) due to cosine's periodic nature.
Explanation:To solve the set of equations Sin(0) = cos (28) and Cos(y) = sin (0), we need to apply trigonometric identities and the given constraints.
Firstly, we can use the co-function identities which state that sin(90° - x) = cos(x), and similarly, cos(90° - x) = sin(x). Therefore, for the first equation, we can express 0 in terms of 28°:
sin(0) = cos(28°) implies 0 = 90° - 28° or 0 = 62°.
For the second equation, we replace 0 with 62°:
cos(y) = sin(62°)
We know that sin(62°) equates to the same value as cos(28°) from the first equation.
Therefore, cos(y) = cos(28°), which means y = 28° or y = 360° - 28° due to the periodic nature of cosine.
