Answer:

9 years

Step-by-step explanation:

Let the present age = x

Age 6 years ago = x - 6

Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18

Twice my present age = 2 *x = 2x

Thrice my age 6 years ago be subtracted from

twice my present age  = 2x -  (3x - 18)

2x - (3x - 18) = x

2x - 3x  + 18 = x                  

    -x  + 18 = x              {Add x to both sides}

             18 = x + x

              18 = 2x              {Divide both sides by 2}

           18/2 = x

x = 9 years

Answer:

y=12.50x

Step by step explantion:

The probability that you do not roll doubles on the first toss, but you do on the second toss  = 13.89%.

Chance is the study of numerical representations of the probability that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, with 1 generally signifying certainty and 0 generally signifying impossibility.

The chances of rolling doubles are 6 out of 36.

The probability is equal to the number of likely outcomes divided by the total number of outcomes:

According to complement rule:

P( not A)=1−P(A)

Then we obtain:

P( not doubles) = 1 - (1/6)

                          = (5/6)

Using Multiplication rule:

P(A∩B)=P(A)×P(B)

Then we obtain:

P(Doubles on second toss) = P( not doubles)×P( doubles)

                                             = (5/6) * (1/6)

                                              = \(\frac{5}{36}\)

                                               = 13.89%

The probability that you do not roll doubles on the first toss, but you do on the second toss  = 13.89%.

Answer:

y = -4x + 2

Step-by-step explanation:

y = mx + b ( slope-intercept)

1. Find Slope:

\(\frac{y^2 - y^1}{x^2 - x^1}\)

Lets name 2 as y2 and 10 as y1. And 0 as x2 and 2 as x1.

\(\frac{2-10}{0-2}\)  =  \(\frac{-8}{2}\) = -4

m/slope = -4

2. Find y-intercept:

\(y = mx +b\)

2 = -4(0) + b

= 2 = b

Y-intercept/b = 2

3. Put into slope-intercept form:

y = mx + b

= y = -4x + 2

Step-by-step explanation:

"t t hours" ????

you mean 11 hours ?

13 gallons now.

2 gallons are used (and therefore disappear from the tank) per hour.

so, in 5 hours 5×2 = 10 gallons will be used.

that leaves 13 - 10 = 3 gallons in the tank.

in 11 hours 11×2 = 22 gallons would have been used.

but there are only 13 gallons in the tank.

so, if he does not fill up, he will have 0 gallons left after 11 hours. in fact, already after 13/2 = 6.5 hours.

the point :

when you use 2 gallons per hour, that means in t hours you are using t × 2 or 2t gallons.

1. The null set or empty set is a set that contains no elements.
2. Null set and empty set are different terms used to describe the same concept.

1. Null Set: The null set, denoted by the symbol Ø or {}, is a set that does not have any elements. It is empty and represents the absence of objects or elements. The null set is a valid concept in mathematics and is used to denote situations where a set has no members.
2. Null Set vs. Empty Set: The terms "null set" and "empty set" are often used interchangeably, referring to the same concept. Both terms represent a set without any elements. The null set is called "null" because it signifies the absence of elements, while the term "empty set" implies that the set is devoid of objects. In other words, null set and empty set describe the same idea of a set with no elements.
Moving on to the other questions:
Q5. Equation with a natural number solution: An example of an equation that yields a natural number solution is: 2x + 3 = 9. When solved, x = 3, which is a natural number because it is a positive integer.
Q6. Subset determination: In example 1, Set A = {rain, snow} and Set B = {snow}. Since all the elements of Set B are also present in Set A, we can conclude that Set B is a subset of Set A. In example 2, Set C = {xlx is strawberry} and Set D = {blueberry, cranberry, raspberry, strawberry}. Here, Set D contains the element "strawberry" from Set C, making Set C a subset of Set D.
Q7. True or False: a) A = {x | x < 5}, F−(x∣) is invalid notation. Without complete information, it is difficult to determine the correctness of this statement.
   b) Set A = {Red, Green} and Set B = {Red, Green, Yellow}. Since all the elements of Set A are also present in Set B, we can conclude that Set A is a subset of Set B.
Q8. Distinct subsets: The given set {t, a, p, e, f, g} has 2^6 = 64 subsets in total, including the empty set and the set itself. However, if we exclude the empty set and the set itself, we are left with 2^6 - 2 = 62 distinct subsets.
In summary, the null set or empty set is a set with no elements. The terms "null set" and "empty set" refer to the same concept. Additionally, we discussed an equation (2x + 3 = 9) that provides a natural number solution (x = 3). We also determined subset relationships between different sets and clarified true or false statements based on the given information. Finally, we calculated the number of distinct subsets for the set {t, a, p, e, f, g} (62 subsets excluding the empty set and the set itself).

These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.

These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.

A linear model is applicable if we can create a linear equation based on the connection between the independent and dependent variables (because there is no constant rate of change).

Otherwise, we can simulate the relationship using an exponential model.

An exponential model is:When the rate of increase representing the relationship between the year and stock price is proportional or constant, we utilize the exponential model.

By determining whether the ratio of the dependent values is the same, one can choose to describe the connection as an exponential equation.

As a result, even though the time and price scatterplot is curved, a linear model is adequate.

Essentially, when it's asking "find the maximum height and the time it occurs at," it wants you to use the vertex formula.  This is a formula that gives you the x-coordinate of the vertex, or the maximum or minimum height of a parabola.

x-coord of vertex = \(\frac{-b}{2a}\)

A quadratic equation is structured with 3 parts

for this one, a = -16, b = 104, c = 5

finding the x-coord just plug those into the formula

\(-\frac{104}{2(-16)}\)

simplify to

- 104/ - 36

negative cancels

104/32

at time = 13/4, there is a relative maximum.

to find its height, just plug that value into your calculator using the original equation

Answer:

No solution.

Step-by-step explanation:

Eliminate the equal sides of each equation and combine.

-4x-5=-4+5

Solve -4x-5=-4x+5 for x by moving all terms containing x to the left side of the equation. Add 4x to both sides of the equation.

-4x-5+4x=5

Combine the opposite terms in -4x-5+4x.

Add -4x and 4x.

0-5=5

Subtract 5 from 0.

-5=5

Since -5=5, there are no solutions.

However, without specific measurements for the angles or sides of the triangle, we cannot determine the lengths of the sides or identify which side is the longest. Therefore, the answer is (a) "cannot be determined."

To determine which side of the triangular rooftop terrace has the greatest length, we need to examine the given information. The lengths of the sides of a triangle are dependent on the measures of the angles and the relative proportions between the sides.

Without knowing any specific values for the angles or sides, we cannot compare or determine the lengths of the sides accurately. Additional information is needed to identify which side has the greatest length.

Answer:

not a real number

Step-by-step explanation:

any negative number under a square root sign, except for 0, isn't real

On evaluating the given roots,

(a) \($-(\sqrt[3]{8}) = -2$\)

(b) \($\sqrt[4]{-81}$\) is not a real number

(a) \($-(\sqrt[3]{8})$\):

The cube root of 8 is the number that, when raised to the power of 3, equals 8. In this case, the cube root of 8 is 2, because \(2^3 = 8\).

Since we have a negative sign in front of the cube root, the result will be the negative value of the cube root of 8.

Therefore, \($-(\sqrt[3]{8}) = -2$\).

(b) \($\sqrt[4]{-81}$\):

The fourth root of a number is the number that, when raised to the power of 4, equals the given number.

In this case, we are looking for the fourth root of -81.

However, the fourth root of a negative number is not a real number. This is because raising a positive number to an even power (in this case, 4) will always result in a positive value, and there is no real number that, when raised to the power of 4, gives a negative result.

Therefore, the fourth root of -81 is not a real number.

The Laplace transform of the given differential equation is (s^2 + 36)Y(s) = s/(s^2 + 36) + 3s + 6.

Solving for Y(s), we get Y(s) = (s/(s^2 + 36)) + (3s + 6)/(s^2 + 36).

Taking the inverse Laplace transform of Y(s), we obtain y(t) = sin(6t) + 3cos(6t) + 2sin(6t).

The Laplace transform of the given differential equation is s^2Y(s) + 36Y(s) = L{cos(6t)}.

Solving this algebraic equation, we find Y(s) = L{y(t)} = L{3} + 6s + L{cos(6t)} / (s^2 + 36).

Finally, taking the inverse Laplace transform of Y(s) gives us y(t).

a) Taking the Laplace transform of both sides of the given differential equation, denoting the Laplace transform of y(t) by Y(s), the equation becomes:

s^2Y(s) + 36Y(s) = L{cos(6t)}

b) Solving the algebraic equation for Y(s), we get:

Y(s) = L{y(t)} = L{3} + 6s + L{cos(6t)} / (s^2 + 36)

c) Taking the inverse Laplace transform of both sides of the equation obtained in part (b), we can solve for y(t):

y(t) = L^(-1){Y(s)}

a) We take the Laplace transform of both sides of the given differential equation, which involves transforming each term individually. The Laplace transform of the second derivative y''(t) is s^2Y(s), and the Laplace transform of 36y(t) is 36Y(s). The Laplace transform of cos(6t) can be obtained from the Laplace transform table.

b) By rearranging the equation from part (a), we isolate Y(s) to solve for it. The Laplace transform of y(0) is L{3}, which is equal to 3/s (since the Laplace transform of a constant is 1/s).

Similarly, the Laplace transform of y'(0) is L{6}, which is equal to 6. We substitute these values into the equation and simplify, resulting in Y(s) = L{y(t)} = L{3} + 6s + L{cos(6t)} / (s^2 + 36).

c) To find y(t), we need to take the inverse Laplace transform of Y(s). This involves finding the inverse Laplace transform of each term in Y(s) individually. The inverse Laplace transform of L{3} is 3 (since the inverse Laplace transform of a constant is the constant itself).

The inverse Laplace transform of 6s is 6δ(t), where δ(t) represents the Dirac delta function. The inverse Laplace transform of L{cos(6t)} / (s^2 + 36) can be obtained from the inverse Laplace transform table. Combining these terms gives us the expression for y(t).

The possible 3rd degree binomial with a constant term of 888 is x^3 + 2x^2 + 3x + 888, for the given one degree of freedom.

To find a 3rd degree binomial with a constant term of 888, we can start by writing the general form of a 3rd degree binomial: ax^3 + bx^2 + cx + d.

Since we want the constant term to be 888, we can set d = 888.

Now, we need to choose values for a, b, and c. We have one degree of freedom, so we can choose any values for a, b, and c as long as they satisfy the condition of being a 3rd degree binomial.

For example, let's choose a = 1, b = 2, and c = 3.

Therefore, a possible 3rd degree binomial with a constant term of 888 is x^3 + 2x^2 + 3x + 888.
