Which equation represents the same proportional relationship as the graph

Answers

The slope of the given linear line is 3/5 thus the equation is y = 3/5 x so option (A) is correct.

What is a linear function?

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given,

The slope of the line is 3/5

Since, the equation is y = mx + c where m is the slope and c is the y-intercept.

In the given line c = 0 and m = 3/5

y = 3/5 x

Hence "The slope of the given linear line is 3/5 thus the equation is y = 3/5 x".

the product of c and 8 is greater than 21​

Answers

Answer:

8c > 21

The solution is c > 21/8.

Step-by-step explanation:

Not all math problems have only one solution. Some math problems have multiple solutions such as set or group of solutions. These problems are called inequalities. Inequalities have solutions within a range using symbols such as >, <, ≤, and ≥. These are known as greater than, less than, less than or equal and greater than or equal. You can write any inequality expression from words into symbols using these signs.

The expression "the product of c and 8 is greater than 21​" is translated into

8c > 21

since product is multiplication.

It can be solved by dividing both sides by 8.

The solution is c > 21/8.

What is Addition?

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

The table shows the number of acres for each park in the two cities.

City A:  6   9   10   7   10   10   2   5   8   8

City B :  5   10   8   11    7    12   6   5   4   5

For City A:

Minimum acre of park = 2

Maximum acre of park = 10

Hence, Range = Maximum-Minimum

Range = 10-2

Range = 8

Now mean is calculated as:

Mean = 6 + 9 + 10 + 7 + 10 + 10 + 2 + 5 + 8 + 8 / 10

          = 75/10

          = 7.5

For City B:

Minimum acre of park = 4

Maximum acre of park = 12

Hence, Range = Maximum-Minimum

Range = 12-4

Range = 8

Now mean is calculated as:

Mean = 5 + 10 + 8 + 11 + 7 + 12+ 6 + 5+ 4 + 5 / 10

         = 73/10

         = 7.3

Hence, The mean number of acres for each park for the two cities is:

City A: 7.5

City B: 7.3

Hence, It is Much greater for City A than for City B.

how many different ways can you arrange four pictures on a wall if you want them in a horizontal straight line​

Answers

Answer:

You can do it four ways for horizontal straight line using a ruler.

Step-by-step explanation:

i did was make a 2x2 grid, and then arrange the four pictures inside.

Final answer:

There are 24 different ways to arrange four pictures on a wall in a horizontal straight line, calculated using the factorial of the number of pictures (4!).

Explanation:

The question of how many different ways you can arrange four pictures on a wall if you want them in a horizontal straight line is a problem of permutations, which is a concept in mathematics. To determine the number of different arrangements, we calculate the factorial of the number of pictures. The factorial, represented by an exclamation mark (!), means that you multiply the number by every number below it down to 1. For four pictures, the calculation is 4! (which is 4 x 3 x 2 x 1).

The result is:

4 x 3 x 2 x 1 = 24

Therefore, there are 24 different ways to arrange four pictures on a wall in a horizontal straight line.

Determine how many points the parabola has in common with the x-axis and whether it's vertex lies above, on, or below the x-axis.

Answers

Points "in common with the x-axis" are also known as the roots of the quadratic equation [tex]x^2-12x+12=0[/tex]. You can apply the quadratic root formula to determine the roots, and also to determine how many such roots there are. With a quadratic (whose graph is a parabola), there can be maximum of 2 roots. But under certain circumstances, there may be only one or no such root.

The root formula for a generic quadratic [tex]ax^2+bx+c[/tex] is as follows:

[tex]x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

The expression [tex]b^2-4ac[/tex] under the square root is called the determinant. It is called so because it determines the number of real roots. If the determinant value is > 0, there will be 2 roots (and so the parabola will cross the x-axis in 2 points), if its value is =0, there will be only a single root (the the parabola will touch the x-axis in exactly one point), and, finally, if its value is < 0, the quadratic has no real root (andthe parabola will not have any x-intercepts).

So, let's take a look:

[tex]b^2-4ac= (-12)^2-4\cdot 1\cdot12=96[/tex]

This means the parabola will intercept the x-axis at 2 points, two real roots.

Since the coefficient of the quadratic term is positive (a=1), the parabola is oriented "open-up." But since we already know the parabola intercepts in two points, the fact that it is open-up implies now that the vertex must lie below the x-axis (otherwise it could not intercept it).

The number of common points between a parabola and the x-axis is determined by the discriminant of its equation, while the position of its vertex relative to the x-axis is determined by the value of y at the vertex. A positive discriminant yields two points of intersection, zero yields one, and negative yields none. The vertex's position can be above, on, or below the x-axis depending on whether k in its vertex form is positive, zero, or negative.

To determine how many points a parabola has in common with the x-axis, we look for the solutions to the parabolic equation when y is set to zero. The number of intersections corresponds to the number of real solutions to this equation. If the parabola's equation is given in the standard form y = ax2 + bx + c, we can use the discriminant (b2 - 4ac) to find out how many times the parabola touches the x-axis. If the discriminant is positive, the parabola intersects the x-axis at two distinct points; if it is zero, the parabola touches the x-axis at exactly one point (the vertex); and if it is negative, the parabola does not intersect the x-axis at all.

The vertex of the parabola lies above, on, or below the x-axis depending on the value of y at the vertex. In the vertex form of a parabola, y = a(x - h)2 + k, where (h, k) is the vertex, if k is positive, the vertex lies above the x-axis; if k is zero, the vertex is on the x-axis; and if k is negative, the vertex lies below the x-axis. Typically, the coefficient a determines the direction of the parabola opening—upwards if a is positive, and downwards if a is negative, but this does not affect the vertical placement of the vertex relative to the x-axis.

a tree 3 feet tall grows 8% each year . how tall will the tree be at the end of 14 years ? round the answer to the nearest hundredth

Answers

Answer:

33.61 ft

Step-by-step explanation:

First you find the product of 3ft and 8%

3.0(0.8)=2.4

Then you find the product of 2.4 and 14years

2.4(14)=33.61

Final answer:

Using the formula for exponential growth, a tree that is initially 3 feet tall and grows at a rate of 8% per year would be approximately 5.23 feet tall at the end of 14 years.

Explanation:

To solve this problem, we can use the formula for exponential growth: Final amount = Initial amount * (1 + Growth rate) ^ Number of periods.

The initial height of the tree is given as 3 feet. This is our initial amount. The growth rate is 8% per year, so we represent this as 0.08 in our formula. The number of periods is 14 years.

So, we have:

Final height = 3 * (1 + 0.08) ^ 14

To find the final height, we multiply 3 by 1.08 raised to the power of 14. Doing the math, the tree would be approximately 5.23 feet tall at the end of 14 years, rounded to the nearest hundredth.

Choose the inequality in that represents the following graph

Answers

Final answer:

The inequality is determined by examining the graph, identifying the lines, their slopes and determining if they are increasing or decreasing. Positive slopes are for increasing lines and negative slopes are for decreasing lines. Inequalities should represent the identified lines and their slopes.

Explanation:

From your question, it seems that there's a graph involved depicting certain lines and you're supposed to choose an inequality that represents the graph. As per the given information that line A is decreasing and line B is increasing, it sounds like these lines may represent an inequality on the coordinate plane. Consider the slope of line A and line B. If one is steeper than the other, the steeper slope has a larger absolute value. An increasing line indicates a positive slope, while a decreasing line indicates a negative slope. For example, if line A is y < -2x + 3 (negative slope, line decreasing) and line B is [tex]y > 5x + 1[/tex](positive slope, line increasing), the inequality would be [tex]y > 5x + 1 - y < -2x + 3.[/tex]For a precise and correct answer, you need to analyze the graph, identify lines, intercepts, slopes, and shading to form the correct inequality.
