What is quadratic equation?
A quadratic equation is a second-order polynomial equation in one variable (x) using the formula ax² + bx + c = 0 and a≠0. The fundamental theorem of algebra ensures that it has at least one solution because it is a second-order polynomial problem. Real or complex solutions are also possible.
According to question.
y = -16t² + 56t+ 4
⇒ -16t² + 56t + 4
⇒ -4t² + 14t + 1
⇒ t = [-14 ±√((14)² - 4*(-4)*1)]/-8
⇒ t = [-14 ±√(212)]/-8
⇒ t = [-14 ± 14.560]/-8
⇒ t = [-14 ± 14.560]/-8
⇒ t = -(28.56)/-8 and t = 0.560/-8
⇒ t = 3.750 and t = 0.070
hence, t = 3.750 and t = 0.070 are, the following x- values, between A) 0 and 1 and D) 3 and 4

Find the equation of the straight line RS. A)y = -2x + 3 B)y = -2x + 6 C)y = 2x + 3 D)y = 2x + 6
The equation of the line passing through the points (0, 6) and (3, 0) is y = -2x + 6.
What is the slope of the equation?
The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).
To find the equation of the line passing through the points (0, 6) and (3, 0), we can use the two-point form:
y - y1 = m(x - x1)
where (x1, y1) is one of the given points, and m is the slope of the line.
To find the slope, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates of the given points, we get:
m = (0 - 6) / (3 - 0)
= -6 / 3
= -2
Substituting this value for m and the coordinates of one of the given points into the two-point form, we get:
y - 6 = -2(x - 0)
Combining like terms and multiplying through the parentheses, we get:
y = -2x + 6
Hence, the equation of the line passing through the points (0, 6) and (3, 0) is y = -2x + 6.

The tide, or depth of the ocean near the shore, changes throughout the day. The depth of the bay can be modeled by d = 35 - 28 cos (π/6. 2 t)
where d is the depth in feet and t is the time in hours. Consider a day in which t = 0 represents 12:00 A. M. At what time is the water depth 14 feet.
(please include explanation)
The exists no solution for which the water depth 14 feet in the ocean near the shore.
Explain the term time period?A time period (T) is the length of time it takes for one complete vibration cycle to pass over a certain location. As the frequency of a wave rises, so does its period. The length of time is expressed in "seconds."We determine the function's period since that is the number of it takes hours for the ocean to return to its original depth of a specific number of feet.
The function's duration is 2π/ (π/6.2) = 12.4 hours.
When t = 0, midnight, or 12:00AM, it is low tide.
As a result, the next low tide will occur at 12:24 PM, or t = 12.4, 12.4 hours from now.
A high tide will occur halfway between those two low tides, at t=6.2 hours after midnight, or at 6:12AM.
Another high tide will occur at t=18.6 hours after midnight, or at 6:36 PM, 12.4 hours later.
If t = 0 is used in the equation, the low tide occurs at that time;
d = 35 - 28cos(pi/6.2)t
d = 35-28cos(pi/6.2)0
d = 35-28cos(0)
d = 35-28(1)
d - 35-28
d = 7
Therefore, there will never be 4 feet there because the lowest depth that may exist is 7 feet.
Thus, the exists no solution for which the water depth 14 feet in the ocean near the shore.

the equation of a line is y = 7x + 8 what is the gradient of the line
Answer:
7
Step-by-step explanation:
The gradient of a line is a measure of how steep the line is. It is calculated as the change in the y-value (the "rise") divided by the change in the x-value (the "run").
In the equation y = 7x + 8, the coefficient of x (7) is the gradient of the line. This means that for every 1 unit change in the x-value, the y-value changes by 7 units.
So the gradient of the line y = 7x + 8 is 7.

The volume of the liquid in the bigger flask which is in the shape of the cone is V = 980π.
What is a cone?
A cone is a recognizable three-dimensional geometric shape with a smooth and curving surface that is directed upward in mathematics. The
Greek word "konos," which denotes a peak or a wedge, is the source of the English word "cone."
The apex is the pointy end, while the base is the level area.
So, the volume of liquid in the bigger flask:
We know that the radius of the bigger flask is 14cm.
The liquid is filled to a height of 15cm.
The volume of cone formula: V = πr²h/3
Substitute values as follows:
V = πr²h/3
V = π(14)²15/3
V = π196*5
V = 980π
Therefore, the volume of the liquid in the bigger flask which is in the shape of the cone is V = 980π.

What is meant by interest rate?A portion of the total loan amount that the borrower is required to pay the lender as interest over a predetermined timeframe. An interest rate is the percentage of a loan, deposit, or borrowing that must be paid in interest each period (called the principal sum). The total amount of interest charged depends on the amount lent or borrowed, the interest rate, the frequency of compounding, and the length of time it was lent, deposited, or borrowed.
Let the capital will be 100
For interest rate 3.5% then the loan amount will be:
100×(3.5/100)=3.5
For interest rate 3% then the loan amount will be:

During the holiday, students went swimming in a local rectangular pool. The pool measures 20 feet by 35 feet. It is surrounded by a patio that is uniform width. Find the width of the patio if the total area of the pool and patio is 1350 sqr feet. Write a quadratic equation to solve the problem.
Answer:
The width of the patio is 3/2 feet.
Step-by-step explanation:
following equation to solve for w:
(20+2w) * (35+2w) = 1350
Expanding the equation, we get:
700 + 140w + 70w^2 = 1350
Subtracting 700 from both sides, we get:
140w + 70w^2 = 650
Dividing both sides by 10, we get:
14w + 7w^2 = 65
We can now solve for w using the quadratic formula:
w = (-b +/- sqrt(b^2-4ac)) / 2a
where a = 7, b = 14, and c = -65. Substituting these values into the formula, we get:
w = (-14 +/- sqrt(14^2-47(-65))) / 2*7
w = (-14 +/- sqrt(196+1820)) / 14
w = (-14 +/- sqrt(2016)) / 14
w = (-14 +/- 44) / 14
To find the width of the patio, we need to find the area of the pool and the area of the patio. Let's call the width of the patio "w". The area of the pool is 20 * 35 = <<20*35=700>>700 square feet. The area of the patio is (20+2w) * (35+2w) = 1350 sqr feet. We can set up the following equation to solve for w:
(20+2w) * (35+2w) = 1350
Expanding the equation, we get:
700 + 140w + 70w^2 = 1350
Subtracting 700 from both sides, we get:
140w + 70w^2 = 650
Dividing both sides by 10, we get:
14w + 7w^2 = 65
We can now solve for w using the quadratic formula:
w = (-b +/- sqrt(b^2-4ac)) / 2a
where a = 7, b = 14, and c = -65. Substituting these values into the formula, we get:
w = (-14 +/- sqrt(14^2-47(-65))) / 2*7
w = (-14 +/- sqrt(196+1820)) / 14
w = (-14 +/- sqrt(2016)) / 14
w = (-14 +/- 44) / 14
This means that the width of the patio is either 3/2 or -5/2 feet. Since the width cannot be negative, the width of the patio must be 3/2 feet.
The quadratic equation we can use to solve this problem is:
w^2 + 14w - 65 = 0

Work out how much water is in the pot if it boils in 220 seconds.
The relationship between the time it takes to boil a pot of water, T (in seconds), and the amount of water, A (in litres),

2.96 liters of water will boils in 220 seconds.
what is equation?An equation is a mathematical statement that shows that two expressions are equal.
what is proportionality constant?A proportionality constant is a coefficient that relates two quantities that are proportional to each other. In other words, if two quantities are proportional, their ratio is always the same, and this constant ratio is the proportionality constant.
This proportionality can be written as an equation by introducing a constant of proportionality, k:
T = k * A
We are given that it takes 200 seconds to boil 2.7 litres of water, so we can set up an equation using this information:
200 = k * 2.7
Solving for k, we find that k = 200/2.7 = 74.07407407407407.
Now that we know the value of the constant of proportionality, we can use it to find the amount of water in the pot if it boils in 220 seconds. We can set up the following equation:
220 = 74.07407407407407 * A
Solving for A, we find that the amount of water in the pot is A = 220 / 74.07407407407407 = 2.962962962962963 litres.
