Step-by-step explanation:

The quadratic formula is:

\(\begin{array}{*{20}c} {\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} \end{array}\). Assuming that the x² term is a, the x term is b, and the constant is c, we can plug the values into the equation.

\(\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {8^2 - 4\cdot-4.9\cdot1} }}{{2\cdot-4.9}}} \end{array}\)

\(\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {64 + 19.6} }}{{-9.8}}} \end{array}\)

\(\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {83.6} }}{{-9.8}}} \end{array}\)

\(\begin{array}{*{20}c}{\frac{{ - 8 \pm \sqrt {9.14} }}{{-9.8}}} \end{array}\)

\(\frac{-8 + 9.14}{-9.8} = -0.12\)

\(\frac{-8-9.14}{-9.8} =1.75\)

Step-by-step explanation:

To find:-

Answer:-

We are here given that the area of MsTilly's garden is 28¼ yards² and the width of the garden is 2½ yards. We are interested in finding out the length of the graden.

Since the garden is rectangle, we can find out it's area as ,

→ Area = length*width

On substituting the respective values, we have;

→ 28¼ = l * 2½

Convert the given mixed fractions into improper fractions as ,

→ 113/4 = l * 5/2

Divide both the sides by 5/2 as ,

→ 113/4 ÷ 5/2 = l

Simplify,

→ 113/4 * 2/5 = l

→ l = 113/10

Convert the improper fraction into mixed fraction as ,

→ l = 11³/₁₀ yards

Hence the length of the garden is 11³/₁₀ yards .

Answer:

The length of Ms Tilly's garden is 11 ³/₁₀ yards.

Step-by-step explanation:

We can model Ms Tilly's garden as a rectangle.

The area of a rectangle is the product of its width and length:

\(\boxed{\sf Area\;of\;a\;rectangle=width \times length}\)

Given that the area of the garden is 28 ¹/₄ square yards and its width is 2 ¹/₂ yards, we can substitute these values into the formula and solve for length to find the length of her garden.

As the values are mixed numbers, begin by converting them into improper fractions.

To convert a mixed number into an improper fraction, multiply the whole number by the denominator of the fraction, add this to the numerator of the fraction, and place the answer over the denominator:

\(\implies 28 \frac{1}{4}=\dfrac{28 \times 4+1}{4}=\dfrac{113}{4}\)

\(\implies 2 \frac{1}{2}=\dfrac{2 \times 2+1}{2}=\dfrac{5}{2}\)

Now substitute the values into the area formula:

\(\begin{aligned} \textsf{Area of the garden}&=\sf width \times length\\\\\implies \dfrac{113}{4}&=\dfrac{5}{2} \times \sf length\end{aligned}\)

To solve the equation for length, divide both sides by ⁵/₂.

Remember that dividing by a fraction is the same as multiplying by the reciprocal of that fraction. Therefore, we can multiply both sides of the equation by ²/₅:

\(\begin{aligned} \textsf{Area of the garden}&=\sf width \times length\\\\\implies \dfrac{113}{4}&=\dfrac{5}{2} \times \sf length\\\\\implies \dfrac{2}{5} \times \dfrac{113}{4}&=\dfrac{2}{5} \times\dfrac{5}{2} \times\sf length\\\\\implies \dfrac{2 \times 113}{5 \times 4}&=\sf length\\\\\implies \textsf{length}&=\dfrac{226}{20}\\\\\implies \textsf{length}&=\dfrac{226\div2}{20\div2}\\\\\implies \textsf{length}&=\dfrac{113}{10}\end{aligned}\)

Finally, convert the improper fraction back into a mixed number by dividing the numerator by the denominator:

\(\implies 113 \div 10=11\;\rm remainder\;3\)

The mixed number answer is the whole number and the remainder divided by the denominator:

\(\implies \dfrac{113}{10}=11 \frac{3}{10}\)

Therefore, the length of Ms Tilly's garden is 11 ³/₁₀ yards.

Answer:

j = 24

t = 2

h = 4

Step-by-step explanation:

Three hats, two T-shirts, and one jacket cost $40.

3h + 2t + j = 40

Two hats, two T-shirts, and two jackets cost $60.

2h + 2t + 2j = 60

One hat and three T-shirts cost $10.

h + 3t = 10

3h + 2t + j = 40 (1)

2h + 2t + 2j = 60 (2)

h + 3t = 10. (3)

From (3)

h = 10 - 3t

Substitute into (1) and (2)

3(10 - 3t) + 2t + j = 40 (1)

2(10 - 3t) + 2t + 2j = 60 (2)

30 - 9t + 2t + j = 40

20 - 6t + 2t + 2j = 60

- 7t + j = 40 - 30

-4t + 2j = 60 - 20

-7t + j = 10 (1a)

-4t + 2j = 40 (1b)

Multiply (1a) by 2

-14t + 2j = 20

-4t + 2j = 40

Subtract to eliminate j

-4t - (-14t) = 40 - 20

-4t + 14t = 20

10t = 20

t = 20/10

t = 2

Substitute t = 2 into

h = 10 - 3t

h = 10 - 3(2)

= 10 - 6

= 4

h = 4

Substitute t = 2 and h = 4 into

3h + 2t + j = 40

3(4) + 2(2) + j = 40

12 + 4 + j = 40

16 + j = 40

j = 40 - 16

= 24

j = 24

Answer:

(1, 2 )

Step-by-step explanation:

x + y = 3 (subtract x from both sides )

y = 3 - x → (1)

2x - y = 0 → (2)

Substitute y = 3 - x into (2)

2x - (3 - x) = 0

2x - 3 + x = 0

3x - 3 = 0 ( add 3 to both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into (1)

y = 3 - 1 = 2

solution is (1, 2 )

The solution to the System of equations is (x,y) = (4,-3).

We are given two equations:

3y + 13 = x (Equation 1)

5x + 4y = 8 (Equation 2)

We can use Equation 1 to express x in terms of y by subtracting 3y from both sides and then subtracting 13 from both sides:

x = 3y + 13 (Equation 3)

We can then substitute Equation 3 into Equation 2 in place of x:

5(3y + 13) + 4y = 8

Simplifying and solving for y, we get:15y + 65 + 4y = 8

19y = -57

y = -3

Now that we have the value of y, we can substitute it into Equation 3 to find the corresponding value of x:x = 3y + 13 = 3(-3) + 13 = 4

Therefore, the solution to the system of equations is (x,y) = (4,-3).

The statement a base class cannot contain a pointer to one of its derived classes is false because a base class can indeed contain a pointer to one of its derived classes.

In object-oriented programming, a base class can have a pointer to one of its derived classes. This is known as upcasting or polymorphism. Upcasting allows for the flexibility of treating derived class objects as instances of the base class.

By using pointers, a base class can refer to derived class objects and access their member functions and variables. This enables the base class to work with different derived classes without needing to know their specific types.

Pointers to derived classes can be stored in base class member variables or passed as function parameters. This allows for dynamic binding and the ability to invoke overridden functions based on the actual derived class type at runtime.

This concept is fundamental to achieving polymorphism and code reusability in object-oriented programming languages like C++ and Java. It facilitates the implementation of inheritance hierarchies and the ability to work with objects of different derived classes through a common base class interface.

To develop the Branch and Bound (B&B) tree for the given problem, follow these steps:

1. Start with the initial B&B tree, where the root node represents the original problem.

2. Choose \($x_1$\) as the branching variable at node 0. Add two child nodes: one for

\($x_1 \leq \lfloor x_1 \rfloor$ \\(floor of $x_1$) and one for $x_1 \geq \lceil x_1 \rceil$ (ceiling of $x_1$).\)

3. At each node, perform the following steps:

  - Solve the relaxed linear programming (LP) problem for the node, ignoring the integer constraints.

  - If the LP solution is infeasible or the objective value is lower than the current best solution, prune the node and its subtree.

  - If the LP solution is integer, update the current best solution if the objective value is higher.

  - If the LP solution is non-integer, choose the fractional variable with the largest absolute difference from its rounded value as the branching variable.

4. Repeat steps 2 and 3 for each unpruned node until all nodes have been processed.

5. The node with the highest objective value among the integer feasible solutions is the optimal solution.

6. Optionally, backtrace through the tree to retrieve the optimal solution variables.

Note: The specific LP problem and its constraints are missing from the given question, so adapt the steps accordingly.

Step-by-step explanation:

Finding Slope from a Graph relies on knowing that Slope is a ratio between the difference in the y-values divided by the difference in the x-values. When finding the slope, you must first find the difference in y-values in the graph. To Find Slope from a Graph you find two points on the line. You then count how many spaces you have to go up by or down by. If you go up, the y-difference is positive and if you go down the y-difference is negative.You must then find the difference in the x-values in the graph.You use the same two points as when you found the y-difference, except this time you could how many spaces you go left or right. If you go right, the x-difference is positive and if you go down the x-difference is negative. The last step is to divide the difference in the y-values by the difference in the x-values.
