Thus, the equation for the u using the separable differential equation is found as:  \(e^{-4u}\) / (-4)  =  \(e^{9t}\)/9 +  \(e^{-56}\) / (-4)  - 1/9 .

Differential equations that can have their variables separated to determine the equation's solution are known as separable differential equations. The formula for a separable differential equation is dy/dx = f(x) g(y), where x and y are variables that are explicitly separable from one another.

du / dt= \(e^{4u+9t}\)

du/ dt = \(e^{4u}\).\(e^{9t}\)

Now, separate the  u and t terms on different sides:

du/ \(e^{4u}\) =  \(e^{9t}\).dt

\(e^{-4u}\) .du =  \(e^{9t}\).dt

Now, integrating both side:

\(e^{-4u}\) / (-4)  =  \(e^{9t}\)/9 + c  ..eq 1

u(0) = 14

Put t = 0, u = 14

c =  \(e^{-4u}\) / (-4)  - \(e^{9t}\)/9

c =  \(e^{-4*14}\) / (-4)  - \(e^{9*0}\)/9

c =  \(e^{-56}\) / (-4)  - 1/9

Put in eq 1

\(e^{-4u}\) / (-4)  =  \(e^{9t}\)/9 +  \(e^{-56}\) / (-4)  - 1/9

Thus, the equation for the u using the separable differential equation is found as:  \(e^{-4u}\) / (-4)  =  \(e^{9t}\)/9 +  \(e^{-56}\) / (-4)  - 1/9 .

There are 2 tablespoons in an ounce. So for 2 ounces, you will need 4 tablespoons, for 4 ounces 8 tablespoons, and so on.

A tablespoon is a unit of volume measurement in United States, and some other countries. It is equal to approximately 15 milliliters (0.51 fluid ounces). One tablespoon can be further divided into three teaspoons, meaning that one tablespoon is equal to three teaspoons.

In the United States, one tablespoon is equal to 0.5 ounce, which is equal to 14.3 grams. This is slightly different in the UK, where one tablespoon is equal to 0.6 ounces (which is equal to 17.7 grams). To convert tablespoons to ounces, you can use the following formula is 1 tablespoon = 0.5 ounces.

The graph which shows the solution to the system of linear inequalities is given below.

Suppose there is inequality given as: y ≥ f(x)

The region it covers is the region of value pairs (x,y) for which this inequality holds true.

We've to draw the region covered by it.

For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).

We just need to figure out this fact at 1 point on either side of the graph of the function y = f(x) , and then the area where y > f(x) is true, along with the curve of the function y = f(x) is included in the region covered by inequality y ≥ f(x)

We are given that;

The system of linear inequalities x + 5y < 25 and y > 2x + 4

Now,

We would need to graph the two inequalities on the same coordinate plane and shade in the region that satisfies both inequalities.

The first inequality, x + 5y < 25, can be graphed by first graphing the line x + 5y = 25 (by solving for y, y = (25 - x)/5 = 5 - (1/5)x) and then shading in the region below the line.

The second inequality, y > 2x + 4, can be graphed by first graphing the line y = 2x + 4 and then shading in the region above the line.

The solution to the system of linear inequalities is the region that satisfies both inequalities, which is the shaded region that is below the line x + 5y = 25 and above the line y = 2x + 4.

Therefore, by the given inequalities the answer will be given below

Step-by-step explanation:

(x,y) becomes (-x,y) when reflected over the x-axis

Answer: A, B and D.

Step-by-step explanation:

We have two numbers, x and y.

And we know that:

x + y is a negative number.

Then it can happen if:

1) x and y are negative numbers.

remember that when we add two negative numbers, for example -2 and -3 we have:

-2 + (-3) = -5

The sum of two negative numbers is always negative.

2) we have a positive and a negative number, but the absolute value of the negative number is larger than the absolute value of the positive.

For example, if we have -5 and 3.

The positive number is 3 and the negative is -5

and I-5I > I3I

Then when we add those:

-5 + 3 = -2

The result is also a negative number.

Then the correct options are:

A. Both numbers are negative.

B. x is negative, and |x| > |y|. (here says that the negative number is larger in absolute value than the other)

D. y is negative, and |x| < |y|. (this is similar as above, but in this case the negative number is y)

Greg will earn $36.30 in 2 years, to the nearest cent. The interest earned will be $36.30 - $30 = $6.30.

To calculate the interest that Greg will earn in 2 years, you can use the formula for compound interest:

\(A = P(1 + r/n) ^ {nt}\)

where A is the total amount of money after earning interest, P is the principal (initial amount of money), r is the annual interest rate, n is the number of times per year that interest is compounded, and t is the number of years.

Plugging in the values for this problem, we get:

\(A = $30(1 + 0.10/1) ^ {1*2}\\= $30(1.10) ^ 2\\= $30(1.21)\\= $36.30\)

So Greg will earn $36.30 in 2 years, to the nearest cent. The interest earned will be $36.30 - $30 = $6.30.

The relation R is not reflexive, but it is symmetric and transitive.

A homogeneous relation R over the set A, which comprises the elements x, y, and z, is known as a transitive relation. If R relates x to y and y to z, then R likewise relates x to z.

For x, y ∈ Z, xRy if and only if (x+y)² ≡ ±1.

(a) Reflexivity: For x ∈ Z, we have (x + x)² = 4x² ≡ 0 (mod 1), which is not equal to ±1. Therefore, xRx does not hold for any x ∈ Z, and R is not reflexive.

(b) Symmetry: For x, y ∈ Z, if xRy, then (x + y)² ≡ ±1. This implies that (y + x)^2 ≡ (x + y)² ≡ ±1. Therefore, yRx also holds, and R is symmetric.

(c) Transitivity: For x, y, z ∈ Z, if xRy and yRz, then (x + y)² ≡ ±1 and (y + z)² ≡ ±1. Expanding these expressions, we get:

(x + y)² ≡ ±1  =>  x² + 2xy + y² ≡ ±1

(y + z)² ≡ ±1  =>  y² + 2yz + z² ≡ ±1

Adding these two equations, we get:

x² + 2xy + y² + y² + 2yz + z² ≡ ±2

Simplifying, we get:

x² + 2xy + 2yz + z² ≡ ±2 - 2y²

Now, we need to show that (x + z)² ≡ ±1. Expanding (x + z)², we get:

(x + z)² = x² + 2xz + z²

Substituting x² + 2xy + 2yz + z² ≡ ±2 - 2y², we get:

(x + z)² ≡ 2 - 2y² + 2xz

To complete the proof, we need to show that there exists some integer k such that 2 - 2y² + 2xz - k² ≡ ±1. We can rewrite this expression as:

2xz - k² ≡ 2y² - 3 (mod 4)

Since the left-hand side is even, the right-hand side must also be even. Therefore, y² ≡ 1 (mod 4), which implies that y is odd.

Now, we can substitute y = 2m + 1 for some integer m, and simplify:

2xz - k² ≡ 8m² + 8m - 1 (mod 4)

We can rewrite the right-hand side as 4(2m² + 2m) - 1, which is congruent to -1 (mod 4). Therefore, there exists some integer k such that 2xz - k² ≡ ±1, which implies that (x + z)² ≡ ±1. Hence, xRz holds, and R is transitive.

In summary, the relation R is not reflexive, but it is symmetric and transitive.

Answer:

She has 27 quarters

Step-by-step explanation:

Let:

x = Number of nickels

y = Number of quarters

US$0.05 = 5 cents = monetary value of a nickel

US$0.25 = 25 cents = monetary value of a quarter

                      x + y = 68

                     x = 68 - y  ---- --------  (equation i)

                0.05x + 0.25y = 8.80----- (equation ii)

These two are linear simultaneous equations, which can be solved either by substitution, elimination or graphical method.

Substitution method:

Substitute (equation i) into (equation ii) to solve for y:

0.05(68 - y) + 0.25y = 8.80

Expand the brackets by applying the Distributive Law and then bring all the like terms together. y needs to be isolated and made the subject of the equation:

= 3.4 - 0.05y + 0.25y = 8.80

= 0.25y - 0.05y = 8.80 - 3.40

= 0.20y = 5.40

= y = \(\frac{5.40}{0.20}\)

∴ y = number of quarters = 27

Answer:

m∠W = 125°

m∠X = 55°

m∠Z = 55°

Step-by-step explanation:

The shape is parallelogram WXYZ. m∠Y = 125.

A parallelogram is a quadrilateral shape in which both opposite sides and opposite angles are equal to each other. The diagonals of a parallelogram bisect each other. Also consecutive angles in a parallelogram are supplementary.

Therefore in parallelogram WXYZ:

m∠Z + m∠Y = 180° (Consecutive angles in a parallelogram are supplementary)

m∠Z + 125 = 180

m∠Z = 180 - 125

m∠Z = 55°

m∠W = m∠Y (Opposite angles are equal)

m∠W = 125°

m∠W + m∠X = 180° (Consecutive angles in a parallelogram are supplementary)

m∠X + 125 = 180

m∠X = 180 - 125

m∠X = 55°

Answer:the 3rd option

Step-by-step explanation:

The correct option is,

⇒ Some people are being less than honest because P (x ≥ 0.26) is less than 5%.

We have to given that,

In a survey of 1316 people, 926 people said they voted in a recent presidential election. Voting records show that 68% of eligible voters actually did vote.

And, 68% of eligible voters actually did vote.

We can used the formula,

z = √n (p' - p) / √p(1-p)

Substitute all the values, we get;

z = √1316 (925.5/1316 - 0.68) / √0.68 (1 - 0.68)

z = 1.80

Hence, The probability that among 1316 randomly selected voters, at least 926 actually did vote is,

P (X ≥ 926) = P (Z ≥ 1.809..) = 0.035 < 0.05
