Answer 1

Answer:

A

Step-by-step explanation:

You just find out which number is closer to the speed of light

Answer 2

Answer:

9x10^15

Step-by-step explanation:

9,460,528,400,000,000

If you count the numbers up until 9 you get 15. So the easy hack is to just count the numbers up until the VERY first then whichever answer had that number is the right one.

Quadrilateral VWXY is a rectangle.

Properties of a rectangle,

Opposite sides of a rectangle are equal.Diagonals of a rectangle bisect each other.Diagonals are equal in measure.

YX = VW = 31 units

VY = WX = 19 units

By applying Pythagoras Theorem in right triangle ΔWXY,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

(WY)² = (WX)² + (XY)²

YW = [tex]\sqrt{19^2+31^2}[/tex]

Consider the quadratic function y = 1/5(x - 2)2 + 5.
Which statements are true about the function and its graph? Select two options.
The vertex of the function is (-2,5).
There are no real roots for the function.
The graph of the function opens down.
The graph contains the point (2,5).
The graph intersects the x-axis at one unique point.

Answers

Answer:

Step-by-step explanation:

There are no real roots and the graph contains point (2,5). Notice it is in vertex form. So there must be a point at x = 2 and y = 5. However, if it is the vertex and it opens upwards, that means it cannot intersect the x axis. So 2 and 4 are the correct answers I believe.

For the given value of sin, the value of cosΘ will be 0.73.

What is trigonometry?

A right-angle triangle's sides, angles, and relationship to each other are the subject of the mathematical discipline of trigonometry. The pair ratio of a right-angled triangle is known as the trigonometric ratio.

It is given that, sinΘ= -4√29 / 29

Θ=sin⁻¹(-4√29 / 29)

Θ= -0.74

The value of cosΘ is obtained as,

=cosΘ

=cos( -0.74)

=0.73

Thus, the value of cosΘ will be 0.73.

Answers

Answer:

The value of x = -2

Step-by-step explanation:

Given equation:

2x + 4 = 0

Find:

The value of x

Computation:

We know that given equation 2x + 4 = 0 is a liner equation with only one variable.

So, we can solve this by elimination method

2x + 4 = 0

Step 1 :

Subtract 4 from both side

2x + 4 - 4 = 0 - 4

2x = -4

Divide 2 from both side

2x / 2 = -4 / 2

x = -2

The value of x = -2

Answers

Answer: (x + 4)^2 + (y - 3)^2 = 50

Step-by-step explanation:

Given: x^2 + y^2 + 8x - 6y - 25 =0, which the general form of the circle.

Solution:

Complete the square formula: (x - h)^2 + (y - k)^2 = r^2

Group similar term together on the left side of the equation and move the constant to right side of the equation ( remember to change the sign of the constant.

x^2 + y^2 + 8x - 6y - 25 =0

x^2 + 8x + y^2 - 6y = 25

Complete the Square: (x^2 + 8x + _____) + (y^2 - 6y + _____) = 25

Take half of the coefficient of the linear term for each variable, square the quotient, and add the answer to both side of the equation.

half of the coefficient of the linear term: ( 8/2)^2 = 16 and (-6/2)^2 = 9

(x^2 + 8x + 16) + (y^2 - 6y + 9) = 25 + 16 + 9

Each quality is a trinomial square and need to be factored

Hi there!

[tex]\large\boxed{\text{ sum = 180(n - 2)}}[/tex]

This is the formula for finding the sum of interior angles for a polygon with a number of sides "n".

We can also prove this from the table:

Triangle ⇒ 3 sides: 180(3 - 2) = 180°

Quadrilateral ⇒ 4 sides: 180(4 - 2) = 360°

Pentagon ⇒ 5 sides: 180(5 - 2) = 540°

...And so forth. We can write this as for any polygon with "n" sides:

180(n - 2) = sum (°)

They addd up to getting the final answer

The cafeteria bought 200 French bread pizzas for lunch next week. If they had bought the pizza last week while it was on sale, it would only have cost $ 2.00 per pizza. Now, 7 days later, the price is $ 3.78 per pizza. How much money could they have saved if they bought the pizza last week?

Answers

Answer:

$356

Step-by-step explanation:

To solve this problem, use this: (200 * 3.78) - (200 * 2)

(200 * 3.78) - (200 * 2)

200 * 3.78 is the same as 2 * 378, which is 756.

756 - (200 * 2)

200 * 2 is the same as 4 * 100, which is 400.

756 - 400

Subtract 400 from 756 to get 356.

356

If they brought the pizza last week, the school could have saved $356.

The area of a square is 128x3y4 cm2. What is the length of one side of the square in simplest form

Answers

Answer:

We know that the area of the square of side length L is:

A = L*L = L^2

In this case, we know that the area is:

A = 128*x^3*y^4 cm^2

Then we have:

L^2 = 128*x^3*y^4 cm^2

If we apply the square root to both sides we get:

√(L^2) = √( 128*x^3*y^4 cm^2)

L = √(128)*(√x^3)*(√y^4) cm

Here we can replace:

(√x^3) = x^(3/2)

(√y^4)  = y^(4/2) = y^2

Replacing these two, we get:

L = √(128)*x^(3/2)*y^2 cm

This is the simplest form of L.
