If Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute, 3.375 gallons would be in the tub after 3 minutes.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute.

We have to find gallons that would be in the tub after 3 minutes

We can utilize multiplication for the given task,

2/3 minutes = 3/4 gallons

1 minute = 3/4 × 3/2

1 minute =1.125

3 minutes = 3 × 1.125

3 minutes =3.375 gallons

Thus, if Paige is filling her tub at a rate of 3/4 gallons every 2/3 minute, 3.375 gallons would be in the tub after 3 minutes.

He might use the equation y = (3/2) x to determine how much flour he required for the cake.

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, etc.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation.

To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" symbol in it.

According to our question-

Accordingly, we require 2.3 cups of sugar for every cup of flour.

It also means that you need 3 1/2 cups of flour for every cup of sugar.

Therefore, if x cups of sugar and y cups of flour, respectively, are used:

Answer:

There is no solution to this problem. It is not possible to find three numbers that form an arithmetic sequence and, when 1, 3, and 9 are added to them respectively, form a geometric sequence.

Step-by-step explanation:

To find the three numbers in the arithmetic sequence, let's call the first number in the sequence "a," the second number "a + d," and the third number "a + 2d," where "d" is the common difference between the numbers. The sum of these three numbers is:

a + (a + d) + (a + 2d) = 15

This simplifies to:

3a + 3d = 15

To find the three numbers in the geometric sequence, let's call the first number in the sequence "b," the second number "r * b," and the third number "r^2 * b," where "r" is the common ratio between the numbers. The sum of these three numbers is:

b + (r * b) + (r^2 * b) = 15 + b + (r * b) + (r^2 * b)

This simplifies to:

b(1 + r + r^2) = 15 + b + br + br^2

We are told that if 1, 3, and 9 are added to the three numbers in the arithmetic sequence, we get the three numbers in the geometric sequence. Therefore, we can set up the following system of equations:

3a + 3d = 15

b(1 + r + r^2) = 15 + b + br + br^2

Subtracting b from both sides of the second equation gives:

b(1 + r + r^2) - b = 15 + br + br^2

This simplifies to:

b(r^2 + r - 1) = 15 + br + br^2

Subtracting br and br^2 from both sides gives:

b(r^2 + r - 1) - br - br^2 = 15

This simplifies to:

b(r^2 + r - 1 - r - r^2) = 15

This simplifies to:

b(r - 1)(r + 1) = 15

Dividing both sides by (r - 1)(r + 1) gives:

b = 15 / (r - 1)(r + 1)

We are told that the three numbers in the arithmetic sequence add up to 15, so we can substitute 3a + 3d = 15 into the equation above to solve for "b":

3a + 3d = 15

b = 15 / (r - 1)(r + 1)

Substituting 3a + 3d = 15 into the equation above gives:

b = 15 / (r - 1)(r + 1)

Substituting b = 15 / (r - 1)(r + 1) into the second equation gives:

15 / (r - 1)(r + 1)(1 + r + r^2) = 15 + 15 / (r - 1)(r + 1) + 15 / (r - 1)(r + 1)*r + 15 / (r - 1)(r + 1)*r^2

This simplifies to:

15 / (r - 1)(r + 1)(1 + r + r^2) = 15 + 15r + 15r^2

Multiplying both sides by (r - 1)(r + 1) gives:

15 = 15 + 15r + 15r^2

Subtracting 15 from both sides gives:

0 = 15r + 15r^2

Subtracting 15r^2 from both sides gives:

0 - 15r^2 = 15r

This simplifies to:

-15r^2 = 15r

Dividing both sides by -15 gives:

r^2 = r

Solving for "r" gives:

r = 1 or r = 0

If "r" is equal to 1, then the common ratio between the numbers in the geometric sequence is 1, which means that the three numbers in the geometric sequence are the same. This does not satisfy the condition that the three numbers in the geometric sequence are formed by adding 1, 3, and 9 to the three numbers in the arithmetic sequence, so we can eliminate this solution.

If "r" is equal to 0, then the common ratio between the numbers in the geometric sequence is 0, which means that the three numbers in the geometric sequence are all 0. This does not satisfy the condition that the three numbers in the geometric sequence are formed by adding 1, 3, and 9 to the three numbers in the arithmetic sequence, so we can eliminate this solution as well.

Therefore, there is no solution to this problem. It is not possible to find three numbers that form an arithmetic sequence and, when 1, 3, and 9 are added to them respectively, form a geometric sequence.

It takes 1 second  for the ball to reach its highest point.

Acceleration of gravity is the acceleration by which earth pulls

objects towards itself. Acceleration is the rate of change of speed.

Given,

The initial velocity of the ball = 16 feet/second

The initial height of the ball = 10 feet

The ball will first travel upward with an initial velocity of 16 feet/second

and the ball will reach a height of x feet from the point of release. After

that the ball will travel a total downward distance of (10+16) = 26 feet.

At highest point, velocity=0.

Applying, v = u + at

                0 = 16 + (-16)t

                t = 16/16

                t = 1 second

The APR for this loan is equal to 468%.

In Mathematics, APR is an abbreviation for annual percentage rate and it can be defined as a measure of an amount of money based on a yearly rate of interest, which a borrower must pay on a loan or credit card.

Mathematically, the annual percentage rate (APR) of a loan can be calculated by using this formula:

APR = [((simple interest/principal)/n) × 365] × 100

Where:

n represents the number of days.

Note: n is equal to 14 days (2 weeks).

Next, we would determine the FC for this loan as follows;

FC = $295 - $250

FC = $45.

For the two-week period, we have;

Interest = 45/250

Interest = 0.18.

Therefore, the annual percentage rate (APR) of this loan is given by;

APR = 0.18 × 52/2

For the given right triangle the measure of the remaining angles are 2.9° and 87.1° and the remaining sides are 5.9 cm and 116.85 cm respectively.

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

Given that,

In a right triangle tan(P) = 0.051

And, hypotenuse = 117 cm.

The given data can be shown in the diagram as follows,

From the diagram it can be written as,

tan(P) = 0.051

=> P = 2.9°

Then, ∠Q = 180° - (90° + 2.9°)

                = 87.1°

Now, Sin(P) = p/117

        => Sin(2.9°) = p/117

        => p = 117 × Sin(2.9°)

                = 5.9

Similarly, Cos(P) = q/117

            => Cos(2.9°) = q/117

             => q = 117 × Cos(2.9°)

                      = 116.85

Hence, the measure of the remaining angles are 2.9° and 87.1° and the remaining sides are 5.9 cm and 116.85 cm respectively.

Any 3rd-degree polynomial function has 3 zeros. (This is the fundamental theorem of algebra.)

Descartes' rule of signs says the one sign change in the coefficients (--++) means there is one positive real root. On its face, this means there will be 0 or 2 negative real roots.

The value of f(0) is positive (40), and the value of f(-1) is negative (-3), so there must be two negative real roots. (F(x) is positive for very large negative x, so there must be two x-intercepts for x < 0.)

Additional comment

The "steps" are to find the degree of the polynomial. It is 3, so there are 3 zeros. It is not complicated.

What is more complicated is finding their values. The checks we described above can tell whether there are 1 or 3 real roots. (An odd-degree polynomial always has at least 1 real root.) A graph is helpful for finding whether the roots are real or complex, rational or irrational.

Here, any rational roots must be integer divisors of the constant term, 40. We know the root between 0 and -1 is irrational, so all of them are.

The above root values were obtained by Newton's Method iteration, starting from the approximate values shown on the graph.
