Answer:

X=60

Step-by-step explanation:

Firstly you must know that a triangle has 180° angle in it's all side.. so in this case you can say x+½x+(1,5)x= 180°

here x equal to 60°

this is a simple way to expres how can find the x angle

And to second way about how to find the x we have to know the lineer algebra. so lineer algebra is a strong way and useful to not only geometric shapes and for all mathematic calculate..

Answer:

In the equation X + y = 9, X and y are variables. Variables are used to represent unknown quantities or quantities that can vary. In this case, X and y represent two unknown numbers whose sum is equal to 9. We can use algebraic techniques to solve for either X or y, or both, depending on the situation. The values of X and y could represent anything, such as the number of apples and oranges in a basket, the length and width of a rectangle, or the ages of two people.

The image of the point after the reflection is (-3, -6).

To reflect a point across the y-axis, we simply negate its x-coordinate while keeping the y-coordinate the same.

Thus, the image of point (3, -6) reflected across the y-axis would be (-3, -6).

We can visualize this by drawing a line passing through the point (3, -6) and the y-axis.

The reflection of the point will be at the same distance from the y-axis but on the opposite side.

So, the reflection of the point (3, -6) across the y-axis is (-3, -6).

The x-intercepts are approximately (-1.08, 0) and (-0.42, 0), and the y-intercept is (0, -5).

To find the x-intercepts of a parabola, we set y = 0 and solve for x. Similarly, to find the y-intercept, we set x = 0 and solve for y.

Setting y = 0 in the given equation, we get,

0 = −10x^2 − 16x − 5

We can solve for x by using the quadratic formula:

x = [-(-16) ± sqrt((-16)^2 - 4(-10)(-5))] / (2(-10))

Simplifying, we get,

x = [-(-16) ± sqrt(256 - 200)] / (-20)

x = [-(-16) ± sqrt(56)] / (-20)

x = [8 ± 2sqrt(14)] / (-10)

So the x-intercepts are:

x = [8 + 2sqrt(14)] / (-10) ≈ -1.08

x = [8 - 2sqrt(14)] / (-10) ≈ -0.42

To find the y-intercept, we set x = 0 in the given equation:

y = −10(0)^2 − 16(0) − 5

y = -5

So the y-intercept is -5.

Answer:

x = 10

Step-by-step explanation:

To find:-

Answer:-

We are here given that, E is the midpoint of DF. The value of DE is 45 and that of EF is 3(x+5) . We are interested in finding out the value of "x" .

According to Euclid's first axiom , Things which are half of the same thing are equal to one another. So here;

[tex]\sf:\implies DF = DF \\[/tex]

[tex]\sf:\implies \dfrac{DF}{2}=\dfrac{DF}{2} \\[/tex]

[tex]\sf:\implies DE = EF \\[/tex]

On substituting the respective values, we have;

[tex]\sf:\implies 45 = 3(x+5) \\[/tex]

[tex]\sf:\implies 45 = 3x + 15 \\[/tex]

[tex]\sf:\implies 3x = 45-15\\[/tex]

[tex]\sf:\implies 3x = 30 \\[/tex]

[tex]\sf:\implies x =\dfrac{30}{3}\\[/tex]

[tex]\sf:\implies \red{x = 10}\\[/tex]

Hence the value of x is 10 .

If Miller is going to install baseboard around the perimeter of her room's rectangular floor, s.  it will cost Miller $19.20 to purchase baseboard for her room, assuming an average cost of $0.30 per linear foot requiring baseboard.

To find out how much it will cost Miller to purchase baseboard for her room, we can use the CER (Conversion, Equation, and Re-substitution) strategy.

Conversion:

We can calculate the perimeter of the room by adding the lengths of all four sides:

Perimeter = 2(Length + Width) - 2(Doorway Width)

Perimeter = 2(15 + 20) - 2(3)

Perimeter = 64 feet

So, Miller will need 64 feet of baseboard.

Equation:

To calculate the cost of the baseboard, we can use the formula:

Cost = Length * Cost per linear foot

In this case, the length is 64 feet and the cost per linear foot is $0.30.

Cost = 64 * 0.30

Cost = $19.20

Therefore the final answer is that it will cost Miller $19.20 to purchase baseboard for her room, assuming an average cost of $0.30 per linear foot requiring baseboard.

The circumference and area of the circle with the arc of length 21 meters and a central angle of 287° are 4.35 meters and 1.16 square meters.

An arc of length 21 meters subtends a central angle of 287° in a circle. The circumference of the circle and area are required to be determined.

Here is the solution:

Let us suppose that the radius of the circle is r. Thus, we can write:

r = (L/θ) r = (21/287)

Let us substitute the values of r in the formulae of the circumference of the circle and area of the circle.

Circumference of the circle:

C = 2πr

C = 2π (21/287)

C ≈ 4.35 meters

Area of the circle:

A = πr²

A = π (21/287)²

A ≈ 1.16 square meters

Therefore, the circumference of the circle is 4.35 meters and the area of the circle is 1.16 square meters.

The answer of the given question based on finding the new coordinate of c is  (1, 5). and to determine if the image of Triangle ABC is similar or congruent to the original triangle is AB / A'B' = BC / B'C' = CA / C'A' = √(2).

Congruent triangles are triangles that have the same shape and size. More specifically, if two triangles have exactly the same size and shape, then they are congruent triangles. This means that all the corresponding sides and angles of two triangles are equal. Congruent triangles can be thought of as being identical to each other, but they may be positioned and oriented differently in space.

To rotate a point 180° degrees counterclockwise about the origin, we can simply multiply its coordinates by the matrix:

[ -1  0 ]

[  0 -1 ]

So, the coordinates of the rotated point C would be:

[ -1  0 ]   [ 3 ]

[  0 -1 ]*[ 8 ] =[ -3 ]

           [  1 ]

we translate this point 4 units to the right and 4 units up by adding 4 to the x-coordinate and 4 to the y-coordinate:

[ -3 + 4 ]

[  1 + 4 ] = [ 1, 5 ]

Therefore, the new coordinates of point C are (1, 5).

To determine if the image of triangle ABC is similar or congruent to the original triangle, we can check if the ratios of the corresponding sides are the same. Let's calculate the lengths of the sides of the original triangle:

AB = √((8-3)² + (3-3)²) = 5

BC = √((3-8)² + (8-3)²) = 5*√(2)

CA = √((3-3)² + (3-8)²) = 5

Now, let's calculate the lengths of the sides of the image triangle, using the new coordinates:

A'B' = √((8-1)² + (3-5)²) = 5*√(2)

B'C' = √((1-1)² + (5-8)²) = 3

C'A' = √((1-8)² + (5-3)²) = 5*√(2)

We can see that the ratios of the corresponding sides are the same:

AB / A'B' = BC / B'C' = CA / C'A' = √(2)

Therefore, the image of triangle ABC is similar to the original triangle.

Step-by-step explanation:

The solution to the equation 5x^2 = 30x – 45 is x = 3.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the Equation: 5x² = 30x - 45.

We can start by simplifying the equation by subtracting 30x and adding 45 from both sides to get:

5x² - 30x + 45 = 0

We can further simplify by dividing both sides by 5 to get:

x² - 6x + 9 = 0

This can be factored as (x - 3)(x - 3) = 0, which means that the only solution is x = 3.

what is sphere?

A sphere is a three-dimensional geometric shape that is perfectly round, like a ball. It is defined as the set of all points in space that are equidistant from a given point, called the center of the sphere.

The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius.

Let the radius of Sphere A be denoted by "r", then the radius of Sphere B is 5r.

The volume of Sphere A is V(A) = (4/3)πr³.

The volume of Sphere B is V(B) = (4/3)π(5r)³ = (4/3)π125r³ = 5³(4/3)πr³ = 125(4/3)πr³.

Answer:

the velocity of the man is 5 m/s.

Step-by-step explanation:

The kinetic energy of a moving object is given by the equation:

K.E. = 0.5 * m * v^2

where

K.E. is the kinetic energy

m is the mass of the object

v is the velocity of the object

In this problem, we are given that the man has a mass of 60 kg and a kinetic energy of 750 J.

So,

750 J = 0.5 * 60 kg * v^2

Solving for v:

v^2 = (2 * 750 J) / 60 kg

v^2 = 25 J/kg

v = sqrt(25 J/kg)

v = 5 m/s

Therefore, the velocity of the man is 5 m/s.

Answer:

We can use the Pythagorean theorem to solve this problem. Let's assume that Cari's house is at point A, the airport is at point B, and her grandparents' house is at point C. We know that the distance from A to B is 45 miles and the distance from A to C is 45 miles. We want to find the distance from B to C, which we can call x.

We can form a right triangle with sides AB, AC, and BC. The distance we want to find, x, is the length of the hypotenuse of this triangle (side BC).

Using the Pythagorean theorem, we know that:

AB^2 + AC^2 = BC^2

Substituting in the values we know:

45^2 + 45^2 = x^2

Simplifying:

2025 + 2025 = x^2

4050 = x^2

Taking the square root of both sides:

x = sqrt(4050)

x is approximately equal to 63.64 miles (rounded to two decimal places).

Therefore, the direct distance from the airport to Cari's grandparents' house is approximately 63.64 miles.

Thus, cos x/2 = (sqrt(2))/2 has the solution for x =  4kx ± π/2 in the intervals  [0, 2pi).

The ratio of the hypotenuse to the side adjacent to the acute angle together in right triangle is the cosine function, which is a trigonometric function.

This cosine function for only a specified range of angles is represented graphically by the cos graph. A trigonometric graph's horizontal axis is the angle, which is typically denoted by the symbol, and the y-axis is really the sine function of just that angle. The maximum and minimum values are 1 and 1.

There are amplitudes for both the sine and cosine functions. This is due to the scope limitations of each function. Both functions typically have an amplitude of 1, though this can vary depending on the way the function is constructed.

Given function:

cos x/2 = (sqrt(2))/2

OR,

cos x/2 = √2/2

cos x/2 = cos (2kx ± π/4) , k ∈ R (real number)

x/2 = 2kx ± π/4

x =  4kx ± π/2

Thus, cos x/2 = (sqrt(2))/2 has the solution for x =  4kx ± π/2 in the intervals  [0, 2pi).
