The radical form of the given expression 15x^(1/4) is equal to ( 15 ) × [tex]\sqrt[4]{x}[/tex].

As given in the question ,

Given expression is written as :

15x^(1/4)

Using th formula to conversion of the exponential form into the radical form in general form is given by:

( z )^ ( m / n ) = [tex]\sqrt[n]{z^{m} }[/tex]

Exponential 4 can be written as x^4. This is an exponential expression and is used to represent a repeated multiplication of the base, 4, by itself.

In this case, the base is 4, and the exponent, x, represents the number of times 4 is multiplied by itself. For example, 4^3 can be written as 4x3, which is equal to 4*4*4. This is the same as saying “4 multiplied by itself 3 times.”

Exponential notation is a useful way to express large numbers. For example, 4^10 can be written as 4x10, which is equal to 4,096. The exponential form of this expression allows us to quickly calculate the result without having to write out the entire equation.

Answer: To solve the equation 4x^2 + 5 = 6 by factoring, we need to start by isolating x^2 on one side of the equation.

We have:

4x^2 + 5 = 6

subtracting 5 from both sides:

4x^2 = 1

Dividing both sides by 4:

x^2 = 1/4

Taking the square root of both sides:

x = ± √(1/4)

x = ± 1/2

So the solutions are x = 1/2 or x = -1/2.

It's important to note that we can't factor any x^2 term as it's a squared term and it's not possible to factor it out with any integer or variable.

Step-by-step explanation:

28) The constant of proportionality is (k = 2)

29) x and y do not change in the same way

30) The constant of proportionality (k = 5/xy)

x = 2y shows direct variation because as x increases, y also increases and as x decreases, y also decreases. The constant of proportionality, also known as the "k" value, is 2, it represents the ratio of x to y. (k = 2)

y - x = 6 does not show direct variation because the relationship between x and y is not constant, x and y do not change in the same way.

xy = 5 shows direct variation because as x increases, y also increases and as x decreases, y also decreases. To find the constant of proportionality, we can divide both sides by xy.

k = 5/xy

In this case, the constant of proportionality is not a fixed value, it is a variable depending on the values of x and y. It represents the ratio of xy to the product of x and y.

Answer:

36 square units

Step-by-step explanation:

The figure is made up of a rectangle above with length 6 and width 4.

The bottom part is a triangle with a base of 6 and a height of 4.

total area = area of rectangle + area of triangle

total area = LW + bh/2

total area = 6 × 4 + 6 × 4/2

total area = 24 + 12

total area = 36

Answer:

36 square units

Step-by-step explanation:

We can split the given figure into two familiar figure by drawing a line segment as shown in the attached figure

This splits the composite figure into a rectangle at the top and an inverted triangle at the bottom

The rectangle has a length(horizontal portion) of 6 units and a width(vertical portion) of 4 units

Area of rectangle = length x width = 6 x 4 = 24 square units

The triangle has a base of 6 units and a height of 4 units

Area of rectangle = 1/2 x base x height = 1/2 x 6 x 4 = 1/2 x 24 = 12 square units

Area of figure = 24 + 12 = 36 square units

Answer: 52(4x+8) in simplified form is 208x + 416.

Step-by-step explanation:

To simplify 52(4x+8) we need to first use the distributive property, which states that:

a(b+c) = ab + ac

So, we can rewrite 52(4x+8) as:

52 * 4x + 52 * 8

Now we can just multiply the numbers:

52 * 4x = 208x

52 * 8 = 416

so the expression simplifies to:

208x + 416

So, 52(4x+8) in simplified form is 208x + 416.

Equation represents the comet's orbit [tex]\frac{x^{2} }{100} -\frac{(y-6)^2}{64} =1[/tex], So correct option is C.

A coordinate plane, also known as a Cartesian plane, is a two-dimensional surface that is used to graph points, lines, and shapes. It is named after the mathematician René Descartes, who is credited with inventing the system in the 17th century.

The coordinate plane is divided into four quadrants by two perpendicular lines called the x-axis and y-axis. The point where the two axes intersect is called the origin and is assigned the coordinates (0,0). The x-axis runs horizontally and is used to measure values along the horizontal (or "x") direction, while the y-axis runs vertically and is used to measure values along the vertical (or "y") direction.

Each point on the coordinate plane can be represented by an ordered pair of numbers, called coordinates, that indicate its position in relation to the x- and y-axes. The coordinates of a point are written as (x, y), where x is the point's distance from the y-axis and y is the point's distance from the x-axis.

The equation that represents the comet's orbit is:

[tex]\frac{x^{2} }{100} -\frac{(y-6)^2}{64} =1[/tex]

The angle which would be tangent  a 90 degree in the given diagram would be ∠JYQ, ∠JYW  , ∠FYG and ∠FHG

A circle's tangent is a single-pointed line that intersects the circle. The point of tangency is the location where the circle and the tangent cross. The circle's radius, where the tangent touches it, is perpendicular to it.

Therefore, JY is perpendicular to QW which means

∠JYQ=∠JYW=90 degrees

Since, J is the center of circle and GF is diameter, there is a theorem which says that angle substended by diameter at any point of circle is 90 degree.

In coordinate geometry, the slope of a line, m, is defined as the ratio of the change in y to the change in x of any two distinct points on the line. It can also be written as the ratio of the rise to the run.

What is meant by coordinate geometry?

Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points. Using coordinate geometry, it is possible to find the distance between two points, dividing lines in m:n ratio, finding the mid-point of a line, calculating the area of a triangle in the Cartesian plane, etc.

To find the slope of a line, we can use the two-point form of the equation of a line, which is:

y = mx + b

Where m is the slope and b is the y-intercept.

To find the slope, we can use any two distinct points (x1, y1) and (x2, y2) on the line. To find m1 and m2, we use the following formulas:

m1 = (y2-y1) / (x2-x1)

m2 = (x2-x1) / (y2-y1)

It is important to note that m1 and m2 are the same value, just in different forms. m1 is the slope and m2 is the reciprocal of the slope.

In cases when x2-x1=0 (parallel to y-axis) or y2-y1=0(parallel to x-axis) the slope would be undefined and undefined respectively.

One of the most common ways to represent a line's equation is in the slope-intercept form of a line. When the slope of the straight line and the y-intercept are known, the slope-intercept formula can be used to determine the equation of a line.

Slope-intercept form of a line is y = mx + c

where m = slope and c - y-intercept of the line.

Here we have

Given points (86, 125) and
