y varies as t. If y = 6 when t =4, calculate:
a) the value of y, when t = 6
b) the value of t, when y = 4
Answer:
see explanation
Step-by-step explanation:
given y varies as t , then the equation relating them is
y = kt ← k is the constant of variation
to find k use the condition y = 6 when t = 4
6 = 4k ( divide both sides by 4 )
[tex]\frac{6}{4}[/tex] = k , that is
k = [tex]\frac{3}{2}[/tex]
y = [tex]\frac{3}{2}[/tex] t ← equation of variation
(a)
when t = 6 , then
y = [tex]\frac{3}{2}[/tex] × 6 = 3 × 3 = 9
(b)
when y = 4 , then
4 = [tex]\frac{3}{2}[/tex] t ( multiply both sides by 2 to clear the fraction )
8 = 3t ( divide both sides by 3 )
[tex]\frac{8}{3}[/tex] = t
A 10 kg object is attached to a spring and is pulled 0.5 m from its rest position at an angle of 30 degrees to the horizontal. The spring has a spring constant of k and is compressed 0.3 m. Calculate the potential energy stored in the spring and the rope, taking into account the horizontal and vertical components of the displacement.
Step-by-step explanation:
The potential energy stored in the spring can be calculated using the equation:
PE_spring = 1/2 * k * x^2
where k is the spring constant and x is the displacement of the spring from its rest position. In this case, x = 0.5 m.
The potential energy stored in the rope can be calculated as the gravitational potential energy of the object, which is given by:
PE_rope = m * g * h
where m is the mass of the object (10 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the vertical displacement of the object.
The horizontal and vertical components of the displacement can be calculated using trigonometry:
x = 0.5 * cos(30) = 0.5 * sqrt(3)/2 m
y = 0.5 * sin(30) = 0.5/2 m
The total potential energy stored in the spring and rope is given by the sum of their individual potential energies:
PE = PE_spring + PE_rope = 1/2 * k * x^2 + m * g * h
Substituting in the given values, we find:
PE = 1/2 * k * (0.5 * sqrt(3)/2)^2 + 10 * 9.8 * (0.5/2 + 0.3)
Note: The spring constant (k) is not given, so the answer is given in terms of k.
Answer:
Step-by-step explanation:
The potentpotentialial energy stored in a spring is calculated by 1/2 * k * x^2, where k is the spring constant and x is the displacement from its rest position. The potential energy stored in the rope is calculated as m * g * h, where m is the object's mass, g is acceleration due to gravity and h is the object's vertical displacement. The total potential energy is the sum of these two energies. In this case, the horizontal and vertical components of the displacement can be calculated using trigonometry and then used to find the total potential energy stored in the spring and rope.

-1/3d + 4/5 = 1/2 what is d?
The required value of d in the given arithmetic operation is 9/10.
What are subtraction and addition?
The two main arithmetic operations that we learn to add and subtract two or more integers or other mathematical values are addition and subtraction. To add, one must add two or more numbers or values to produce a new number. The inverse of addition is subtraction and vice versa.
For instance, 10 - 1 = 9 if 9 + 1 = 10. That demonstrates that adding 1 produces the number 10 when added to 9, but subtracting 1 from 10 produces the number 9.
Given, -1/3d + 4/5 = 1/2
[tex]\frac{-1}{3} d+\frac{4}{5} =\frac{1}{2} \\\\\frac{-1}{3} d =\frac{1}{2}-\frac{4}{5}\\\\\frac{-1}{3} d = \frac{5-8}{10}\\\\\frac{-1}{3} d = \frac{-3}{10}\\\\\frac{d}{3}=\frac{3}{10}\\\\d = \frac{9}{10}[/tex]

an unfair coin has probability 0.4 of landing heads. the coin is tossed three times. what is the probability that it lands heads at least once? round the answer to four decimal places.
The probability that it lands heads at least once is 1.0720.
Probability is the measure of the likelihood of an event occurring. In this case, we are looking at the probability of a coin landing heads at least once after three tosses.
Let's denote the event of the coin landing heads on the first toss as event A, the event of the coin landing heads on the second toss as event B, and the event of the coin landing heads on the third toss as event C.
The probability of landing heads at least once is equal to the sum of the probabilities of each individual event occurring (A, B, or C) minus the probability of all three events occurring (A and B and C).
P(A or B or C) = P(A) + P(B) + P(C) - P(A and B and C)
Since the coin is unfair and has a probability of 0.4 of landing heads, P(A) = P(B) = P(C) = 0.4.
Using the formula for the probability of multiple events happening simultaneously, we find that P(A and B and C) = P(A) * P(B) * P(C) = 0.4 * 0.4 * 0.4 = 0.064.
Plugging in all the values, we get:
P(A or B or C) = 0.4 + 0.4 + 0.4 - 0.064 = 1.136 - 0.064 = 1.072
Rounding to four decimal places, the answer is 1.0720, which means that the probability of the coin landing heads at least once after three tosses is 1.0720.

How to derive a cubic polynomial
In this problem we find the case of a cubic polynomial in standard form:
y = a · x³ + b · x² + c · x + d
Where a, b, c, d are real coefficients.
The values of the coefficients must be determined on the knowledge of the leading coefficient (a = 2), the constant term (d = 5) and two values (y(- 1) = 2, f(1) = 14). First, substitute the leading coefficient and the constant term in the definition:
y = 2 · x³ + b · x² + c · x + 5
y - 2 · x³ - 5 = b · x² + c · x
Second, form the system of linear equations by using the given values:
b - c = - 1
b + c = 7
Third, solve the resulting system by numerical methods:
(b, c) = (3, 4)
Fourth, write the resulting polynomial:
y = 2 · x³ + 3 · x² + 4 · x + 5

One of the legs of a right triangle measures 2 cm and the other leg measures 7 cm.
Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
The measure of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides.
For the given triangle, let's call the length of the hypotenuse "h". Then, using the Pythagorean theorem:
h^2 = 2^2 + 7^2
h^2 = 4 + 49
h^2 = 53
h = √53
Rounding to the nearest tenth, h = 7.3 cm.
So, the measure of the hypotenuse of the right triangle with legs of length 2 cm and 7 cm is 7.3 cm.

Tony made cookies of circumference 45 cm. Find the area of each cookie made by tony.
Answer:
the area of each cookie made by Tony is approximately 63.62 square cm.
Step-by-step explanation:
The area of a cookie can be found if we know its radius. To find the radius, we can divide the circumference by 2 times pi (π).
Let's call the radius of the cookie "r".
45 cm / (2 * π) = r
Now that we have the radius, we can find the area using the formula:
π * r^2 = area
So,
π * r^2 = π * (45 / (2 * π))^2 = (45^2) / (4 * π)
Therefore, the area of each cookie made by Tony is approximately 63.62 square cm.

A silo is shaped like a cone and contains wheat. The radius is 10 feet and the height is 15
feet. If the silo can release wheat from its bottom at the rate of 25 cubic feet per minute, how
long would it take for the silo to empty fully? Round your answer to the nearest minute. Use
the approximate value of л, that is 3.14.
The volume of wheat in the silo is about 1,570 feet and it would take about 63 minutes at the given rate for the silo to empty fully.
What is volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Various forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.
The silo is in the shape of cone, so use the formula of volume of a cone to find volume of wheat the tank can hold.
The formula to find volume of a cone is:
V = 1/3 · πr2h -----(1)
Substitute π ≈ 3.14, r = 10 and h = 15 in (1).
V ≈ 1/3 · 3.14 · 102 · 15
V ≈ 1/3 · 3.14 · 100 · 15
V ≈ 1,570
So, the volume of wheat in the silo is about 1,570 feet.
Silo can release wheat from its bottom at the rate of 25 cubic feet per minute.
= 1,570 / 25
= 62.8
≈ 63
Hence, it would take about 63 minutes for the silo to empty fully.
