Answer:

[tex]j = \dfrac{9}{2} = 4,5 \\\\\\k = 2[/tex]

Step-by-step explanation:

I am working on the assumption that the figure shown is a parallelogram, otherwise my answer will not be valid

The diagonals of a parallelogram bisect each other

In the above figure, the top left-bottom right diagonal is bisected by the top right  - bottom-left diagonal

This means

[tex]3j = 5j - 9[/tex]

Subtract 5j from both sides:

[tex]3j - 5j = -9[/tex]

[tex]-2j = -9[/tex]

[tex]j = \dfrac{-9}{-2} = \dfrac{9}{2} = 4,5 \\[/tex]

The solution is

a) The motor boat traveled a displacement of

b) The velocity of the tugboat

c) The negative distances and velocities means the boat is traveling down a river

Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. It is a vector quantity. Velocity is the change in displacement of an object with respect to time

Velocity = Displacement / Time

Given data ,

Some boats are traveling up and down a river

So , when the boat is traveling up a river , the velocity will be positive and when the boat is traveling down a river , the velocity will be negative

a)

The velocity of motor boat = - 3.4 mph

The time taken by the boat = 0.75 hours

Velocity = Displacement / Time

Substituting the values in the equation , we get

Displacement = Velocity x Time

Displacement D = - ( 3.4 ) x 0.75

On simplifying the equation , we get

Displacement D = -2.55 miles

Therefore , the boat traveled -2.55 miles down

b)

The displacement of the tugboat D = -1.5 miles

The time taken by the tugboat T = 0.3 hours

So , velocity of the tugboat V = ( -1.5 ) / 0.3

On simplifying the equation , we get

Velocity V = -5 mph

Therefore , the velocity of the tugboat is -5 miles per hour

c)

When the boat is traveling down a river , the velocity will be negative

Hence , the equations are solved

Oki and Stephen can only produce 0.75 bags of trail mix in total.

Two numbers can have a division symbol (") added between them to indicate that they have been divided. Therefore, we can write 36 6 if we need to demonstrate the division of 36 by 6. A fractional representation is 366, which we can also use.

Compared to multiplication, division is the opposite. When you divide 12 into three equal groups, you get four in each group if three groups of four add up to 12, which they do when you multiply.

The primary objective of division is to count the number of equal groups that are created or the number of individuals in each group after a fair distribution.

The shape that results from a plane passing through a cone that is perpendicular to the base is a B. Circle

A circle intersects a cone when a plane passes through it perpendicular to the base. This is due to the plane cutting through the cone's circular cross-section at a 90-degree angle to the base of the cone.

As a result, if the plane were to be slanted or angled, the intersection would have the shape of an ellipse, which is a circle that has been flattened.

This is due to the fact that an ellipse is the shape created when a plane crosses a cone at an angle other than perpendicular to the base.

The average rate of change from the sixth to the fourteenth hours indicates that, on average, 15 fewer pairs of shoes were sold every hour.

A line's slope determines how steep it is. A mathematical equation for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two spots. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is employed to express it. The y-intercept is located at a location where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).

The given function has one root i.e. -3.

The Synthetic approach can speed up polynomial division, especially when the result needs to be divided by a linear factor. It is often used to find polynomial roots or zeroes rather than dividing components.

In algebra, synthetic division is a technique for manually dividing polynomials according to Euclid, requiring less writing and calculation than long division. Although the approach can be applied to division by any polynomial, it is often taught for division by linear monic polynomials.

We've f(x) = x³-4x+15

Answer: 28%

Step-by-step explanation: So, if we know that Mia's team won 18 of the 25 games they played, we need to subtract 18 from 25. We get 7. So, now we need to use this formula to solve:

Part percent / Whole number * 100

Let's plug in the numbers:

7 / 25 * 100

0.28 * 100

= 28

Therefore, they lost 28% of their games. I hope this helped!

Answer:

28%

Step-by-step explanation:

To find percentages, we need to know the number of games lost out of 25, then multiply it by 4 to get our percentage. We know that she won 18 of 25. 25 - 18 =7, so she lost 7 games. This gives us the fraction:

[tex]\frac{7}{25}[/tex]

Then, we will multiply this fraction by 4 to get it out of 100:

[tex]\frac{28}{100}[/tex]

This gives us 28/100, to find the percentage out of a fraction with a denominator of 100, we multiply by 100 and add a % symbol. This gives us:

[tex]\frac{28}{100} * 100 = 28%[/tex]

Then, we add our percent symbol, meaning Mia's soccer team lost 28% of their games.

Answer: x = -8/3

Step-by-step explanation:

7 = 3(5+x)

3(5+x)=7

apply the distributive property

15+3x=7

rearrange the variables to  the left side of the equation

3x=7-15

3x=-8

divide on both sides

x=-8/3

Answer:

x = -8/3

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 7 = 3(5 + x)

Then the value of x will be,

→ 7 = 3(5 + x)

→ 7 = 3(5) + 3(x)

→ 7 = 15 + 3x

→ 7 - 15 = 3x

→ -8 = 3x

→ 3x = -8

→ [ x = -8/3 ]

Hence, the value of x is -8/3.

2x-1 with a translation 1 unit left followed by a reflection in the x-axis is -2x -1.

What is translation and reflection?

Flipping an object across a line without causing it to change in size or shape is called reflection. An object can rotate around a fixed point without changing its size or shape. Changing a figure's size, shape, or orientation does not constitute translation.

Reflections and translations are two of the most popular types of transformations. An object moves from one location to another through translation, remaining the same size and orientation.

One unit left means  -1 shift on x-axis leads to F(x+1)

Reflection on x-axis means rotating the graph upside down on x-axis which leads -F(x+1)

-F(x + 1) = -2(x + 1) + 1 = -2x - 2 + 1 = -2x -1

Hence, 2x-1 with a translation 1 unit left followed by a reflection in the

Therefore , the solution of the given problem of function comes out to be g(x) is given by g(x) = (x-4)² + 6

The study of numbers, their variations, mathematics and the regional tissue, structures, and both their actual and imagined locations, is known as mathematics. A function is a mathematical representation of the relationship between a set of inputs, each of which has an associated output. A function is a group of inputs that, when combined, result in a single, recognized output for each input. Each function is given a city, town, or scope, which is frequently referred to as a realm.

Here,

Given the graph of the original function f(x), whose vertex is at (0, 0), and indeed the graph of the translating function g(x), whose vertex is at (0, 0), (5, 2).

Be aware that the translated function's vertex is 2 units higher and 5 units to the right of the f graph's graph (x).

The function f(x) is then translated 5 units toward the right и 2 units up to arrive at g(x).

Recall that provided a function, f(x), is characterized as a parabola with a vertex at (h, k).

=> f(x) = (x-h)² + k

When two angles add up to 90°, we say they complement each other in terms of mathematics. Hence in geometry, complementary angles are defined as two angles whose sum is 90 degrees.

we shall represent the smaller angle with the letter x so that;

x + 50° = 90°

subtract 50° from both sides of the equation
