Step-by-step explanation:

divide 190 cm by 91.44 to get your answer.

The triangle JKL is similar to triangle MNL by AA similarity and all three sides of the triangle are equal, so JKL = MNL.

One of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.

Given:

JK || MN and  L is the midpoint of JM,

As the line JK || MN  then,

∠ MNL = ∠ JKL (The alternate angle of the parallel line are equal)

∠ LMN = ∠ LJK (The alternate angle of the parallel line are equal)

∠ JLK = ∠ NLM (The corresponding  angle of the parallel line are equal)

Thus, all the sides will also be equal as the angles are equal.

Hence, the area will also be equal.

So this is an exponential equation. And the dy/dx is impossible because anything time 0 is 0. So there is no Rise over run, most commonly known as your slope.

Option. A ) 0 is correct

It is given that,y = 3x⁰ = 3

we have asked to differentiate the function y with respect to x.

for constants, the slope is always zero and the graph looks like a line parallel to the x-axis

Answer:

Equilateral Triangle

A triangle with all the sides equal is called an equilateral triangle.

Isosceles Triangle

A triangle with at least two sides equal is called an isosceles triangle.

Scalene Triangle

If all the sides of a triangle are unequal, i.e., if the sides are of different lengths, the triangle is called a scalene triangle.

Acute Triangle

An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.

Obtuse Triangle

Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.

Right Triangle

A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse. You may come across triangle types with combined names like right isosceles triangle and such, but this only implies that the triangle has two equal sides with one of the interior angles being 90 degrees.

Using coordinates O(0,0), E(0, 2b), and F(2a, 0) rather than O(0, 0), E(0, b), and F(a, 0) has the advantage of allowing the graph to be stretched or shrunk uniformly in both the x- and y-directions by a factor of 2. This can be useful if the scale of the graph needs to be adjusted, or if the graph needs to be compared to another graph with a different scale. It can also make the graph easier to read if the values of the variables being plotted are very large or very small.

By using coordinates that are multiples of the original coordinates, the shape of the graph is preserved, but the scale is changed. This can be useful if the purpose of the graph is to compare the relationships between different variables, rather than to provide an accurate representation of the actual values of the variables.

The equation of f(x) from the graph if, G(x) = x², is F(x) = 2x² + 3, so option A is correct.

A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Given:

G(x) = x²,

As you can see from the graph, the vertex of the parabola is (0, 3),

Write the equation of a parabola as shown below,

y = a(x - 0)² + 3

y = ax² + 3

Here a is the slope of the parabola,

slope = 4 / 2  (from the graph),

slope = 2

Thus, the equation will be,

y = 2x² + 3 or  F(x) = 2x² + 3

I'm guessing you misspelled 410 as 419, but the equation is y=mx+b

Kim wants the money amount she puts in to pay off her $410 phone, or in other words, add up to $410.

The constant, or b, is 50. The m is 35, and the x is the months.

35m + 50 = 410

Answer: C. 35m + 50 = 410

Step-by-step explanation:

We know the cost is 410, so it will be = 410

We know that she pays 35 each month, which mean it is 35m

She put down 50 at the beginning, so it is + 50

So our equation is

The equation x^2 - 5x + 7 = 0 has no real roots.

We know that the general form of a quadratic equation is:

ax^2 + bx + c =0

The equation we have is:

x^2 - 5x + 7 = 0

On comparing the given equation with the general form of a quadratic equation, we get that:

a = 1, b= -5, and c = 7

If D = b^2 - 4ac < 0, then the roots of the quadratic equation are imaginary or there are no real roots.

Therefore, b^2 - 4ac = (-5)^2 - 4x1x7 = -3<0.

Hence, we conclude that the nature of the roots of the give equationis imaginary, thus it has no real roots.

Answer:

$34.37.

Step-by-step explanation:

To calculate Daniel's local income tax withholding, we first need to determine his taxable income. To do this, we subtract the value of his exemptions from his yearly income: $41,300 - (4 x $900) = $37,500.

Next, we need to convert the local tax rate of 4 3/4% to a decimal by dividing it by 100: 4 3/4% = 0.0475.

Finally, we can calculate Daniel's local income tax withholding by multiplying his taxable income by the local tax rate: $37,500 x 0.0475 = $1,793.75.

To find the amount of local income tax that should be withheld from Daniel's weekly earnings, we simply divide his total local income tax by the number of weeks in a year: $1,793.75 / 52 = $34.37. Therefore, Daniel's local income tax withholding from his weekly earnings should be $34.37.
