Using transformations, we can find that the graph J represents the correct graph of f(x) and h(x).

A transformation is a change to the graph of a parent function. Translations, reflections, and dilations are the three different forms of transformations. A function can be altered either vertically (affecting the y-values) or horizontally (affecting the x-values) (affects the x-values).

[tex]h(x) = (x + 1) (x − 3)[/tex]

[tex]= x^2 --3x + x-3[/tex]

[tex]= x^2- 2x - 3[/tex]

The graph of f(x) = x² is transformed to create the graph of h(x) = 2f(x) = 2x

Now, for  [tex]x = 0, f(x) = 0[/tex] and  [tex]h(x) = 0[/tex]

Therefore, both the graphs h(x) = 0trough the origin.

Now, for   [tex]x = 1, f(x) = 1[/tex]  and [tex]h(x) = 2[/tex]

Therefore, [tex]f(1) < h(1)[/tex]

Hence, the graph J represents the correct graph of f(x) and h(x).

Therefore, the area of triangle XYZ is 2 square units.

Area is a measure of the size of a two-dimensional shape or surface. It is defined as the amount of space inside the boundary of a flat or planar figure, such as a triangle, square, rectangle, or circle. The unit of area is typically square units, such as square meters (m²), square feet (ft²), or square centimeters (cm²).

Here,

To determine the area of triangle XYZ with coordinates (6,1), (2,5), and (10,9), we can use the formula for the area of a triangle:

Area = (1/2) * base * height

where the base is any side of the triangle and the height is the perpendicular distance from the base to the opposite vertex.

Distance between (6,1) and (2,5):

= √((6 - 2)² + (1 - 5)²)

= √(20)

So, the base of the triangle is √(20).

We can use the formula for the distance between a point and a line to do this:

Distance from (10,9) to line passing through (6,1) and (2,5):

= |(10 - 6)(5 - 1) - (2 - 6)(9 - 1)| / √((5 - 1)² + (6 - 2)²)

= 4 / √(20)

So, the height of the triangle is 4 / √(20).

Now, we can plug in the values for the base and height into the formula for the area of a triangle:

Area = (1/2) * base * height

= (1/2) * √(20) * (4 / √(20))

= 2

To make 70 cups of fruit soda with a juice-to-sparkling water ratio of 4:3, Milo will need 40 cups of juice and 30 cups of sparkling water.

If the juice-to-sparkling water ratio is 4:3, then we can write it as 4x:3x, where x is a common factor.

Let's say Milo wants to make a total of 7x cups of fruit soda (since 4x + 3x = 7x). We know that 7x = 70 cups, so x = 10.

Therefore, Milo needs 4x = 40 cups of juice and 3x = 30 cups of sparkling water.

After calculation, we know that the time taken by the lorry is 3 hours and 20 minutes.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.

Military time starts with 0000, also known as "zero hundred hours" or just "zero hundred," at the stroke of midnight.

Then, multiply each hour by one hundred, such that 1 a.m. is equal to 0100 (zero one hundred) hours, 2 a.m. is equal to 0200 (zero two hundred) hours, and so on.

So, we need to calculate the time as follows:

Leaving time = 14:55

Arriving time = 18:15

Then,

14:55 to 15:15 = 20 minutes

You have to construct a probability tree diagram.

(1)/(x)=(1)/(y)-(1)/(z) is an example of an equation that can be used to express z in terms of x and y. z can be expressed in terms of x and y as z= xy+1/y-x.

It is typically written using an equals sign “=” to show that the two expressions on either side of the equals sign are the same.

To solve the equation, it must first be rearranged so that z is on its own side of the equation.

This can be done by multiplying both sides of the equation by x and then subtracting (1)/(y) from both sides.

(1)/(x)=(1)/(y)-(1)/(z)

1-1/y= (x/y-x/z)-1/y

This yields the equation

y-1/y=(x/y-1/y)-(x/z+1/y)

y-1/y= (x-1/y)-(xy+1/zy)

(y-1/y)-(x-1/y)= (-xy)+1/zy

y-x/y= xy+1/zy

y-x=(xy+1)y/zy

Once the equation has been rearranged, the next step is to solve for z.

z= xy+1/y-x

z= xy+1/y-x

Therefore, z can be expressed in terms of x and y as z= xy+1/y-x.

The relationship between the change in x and the corresponding change in y on a graph depends on the slope of the line. The slope of a line is the ratio of the change in y to the change in x, and it represents how steep the line is.

If the line has a positive slope, that means it is slanting upwards from left to right. In this case, an increase in x will result in an increase in y, and a decrease in x will result in a decrease in y. The larger the slope, the more dramatic this effect will be.

On the other hand, if the line has a negative slope, it is slanting downwards from left to right. In this case, an increase in x will result in a decrease in y, and a decrease in x will result in an increase in y. Again, the larger the slope, the more pronounced this effect will be.

The measure of the angle for the first circle is π/4 and the measure of the angle for the second circle is π. Since π is larger than π/4, we can conclude that the angle measure for the second circle is greater than the angle measure for the first circle.

The central angle of a circle is defined as the angle subtended at the center of the circle by an arc on the circumference. The measure of a central angle is proportional to the length of the arc it subtends, and the constant of proportionality is given by the formula:

angle measure = arc length / radius

Using this formula, we can find the measures of the central angles of the two circles:

For the first circle with radius 16 units and arc length 4π, the angle measure is:

angle measure = arc length / radius = (4π) / 16 = π/4

For the second circle with radius 5 units and arc length 5π, the angle measure is:

angle measure = arc length / radius = (5π) / 5 = π

Therefore, the measure of the angle for the first circle is π/4 and the measure of the angle for the second circle is π. Since π is larger than π/4, we can conclude that the angle measure for the second circle is greater than the angle measure for the first circle.

Answer:

We can use trigonometry to solve this problem. Let's call the distance from point A to the boat "x" and the distance from point B to the boat "y". Then we have:

In triangle AOC, tan(12) = OC / x

In triangle BOC, tan(64) = OC / y

We want to find the distance from point A to point B, which is the difference between x and y:

Distance AB = y - x

To solve for x and y, we need to eliminate OC. We can do this by setting the two expressions for OC equal to each other and solving for OC:

tan(12) = OC / x

OC = x tan(12)

tan(64) = OC / y

OC = y tan(64)

x tan(12) = y tan(64)

y = x tan(12) / tan(64)

Now we can substitute this expression for y into the equation for Distance AB:

Distance AB = y - x

Distance AB = x tan(12) / tan(64) - x

We can simplify this expression by factoring out an x:

Distance AB = x (tan(12) / tan(64) - 1)

Now we just need to plug in the values and calculate:

Distance AB = x (0.2174 - 1)

Distance AB = -0.7826 x

Since distance cannot be negative, we know that x > 0. Therefore, the boat is between point A and point B, and the distance from point A to point B is:

Distance AB = x (0.2174 - 1)

Distance AB = -0.7826 x

Distance AB ≈ 1.28 x

We don't know the actual value of x, but we can see that the distance from point A to point B is approximately 1.28 times the distance from point A to the boat when Jaxson measured the angle of depression to be 12 degrees.

Trigonometry is a branch of mathematics that focuses on the relationships between the sides and angles of triangles.

What is angle elevation?

Angle elevation, also known as angle of elevation, is the angle between a horizontal line and a line of sight (or direction) to an object above the horizontal line.

We can use trigonometry to solve this problem. Let's call the height of the cactus "h". Then we can set up the following equation:

tan(26.1) = h / 4.5

To solve for "h", we can first multiply both sides by 4.5:
