According to the question, the greatest place value 299,792,458

First of all, you refer to physics. Physicists detest miles per second estimate units. They would use meters per second (SI units),centimeters per second (CGS or less desirable SI units), or the value 1 (so-called natural units) be dependent on the type of work they are doing experimental.

Second, suppose you are mention to the condition of a vacuum. Light slows down when passing through the other a vacuum.

Third, even if physicists use miles per second as units, the values you gave are quite discrepant. The value 299 792 458 m/s is one of the  values of the international system of units (SI). The speed of light is not explained to be this value, but it is a fixed value regarded as exact to be used in explain what is a meter . If in any case, it is not a calculate value and it has no uncertainty. If we do an exact conversion of this exactly value to miles per second, which is 186282 (39937/100584) m/s .

We see that, the meter per second value you stated is require, the mile per second value is only a rounded approximation and is off by about 0.15 %.

The 299 792 458 m/s value is what physicists use when they are doing calculations as part of their research, because they require the exactness. they will round off to one significant digit (actually the value is correct to three significant digits but it looks like just one) and use 300 000 000 m/s = 3 × 10⁸ m/s, which is almost trivial to multiply or divide by mentally (unlike the 186 000 mi/s) and is only 0.07 % off.

Using the Division Property of Inequality, Paige was able to get x > 12 and solve the inequality -1/2x > -6. Paige solve the inequality correctly.

Given that,

Using the Division Property of Inequality, Paige was able to get x > 12 and solve the inequality -1/2x > -6.

According to the division property of inequality, if we divide an equation's two sides by the same number, the equation doesn't change.

Let's say you have two identically sized pizzas. You divide each one into halves and serve your buddies one half of each pizza. You will have equal pieces of both pizzas left over if you measure the remaining portions.

-1/2x>-6

-1x>-6[tex]\times[/tex]2

-1x>-12

multiplying -1 on both sides we get

The value of x is 3 and the measure of each side of isosceles ΔJKL is:

JK = 11

KL = 11

LJ = 5

We know that, in an isosceles triangle, any two sides of the triangle are equal and the angle opposite to these sides are equal in measure.

In this question, we have been given an isosceles ΔJKL with JK ≅ KL .

Also we have been given,

JK = 4x - 1, KL= 2x + 5 , and LJ = 2x - 1

As JK = KL

⇒ 4x - 1 = 2x + 5

⇒ 4x - 2x - 1 = 2x + 5 -2x

⇒ 2x = 5 + 1

⇒ 2x = 6

⇒ x = 3

So, the value of x is 3.

Now we find the measure of each side of triangle JKL

JK = 4x-1

JK = 4(3) - 1

JK = 12 - 1

JK = 11

Now the side KL

KL = 2x + 5

KL = 2(3) + 5

KL = 11

And LJ = 2x-1

LJ = 2(3) - 1

LJ = 5

Therefore, the value of x is 3 and the measure of each side of isosceles ΔJKL is:

JK = 11

KL = 11

LJ = 5

Answer:

Step-by-step explanation:

f(x)=|x|

f(x) ==> f(x+3): translation of function 3 units to the left, f(x-3) would be translation 3 units right

f(x+3) ==> 3f(x+3): vertical stretch by a factor of 3

f(x+3) ==> -3f(x+3): Reflection over the x-axis, since y value changes over the x-axis while x value changes over the y-axis

-3f(x+3) ==> h(x)=-3f(x+3)+1: Translation one unit up.

The slope of the line passing through the pair of points, (-2 , -4) and (1 , 2), is 2.

The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points. The formula for solving the slope is:

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

where m is the slope

x1 and y1 are the coordinates of one point

x2 and y2 are the coordinates of the 2nd point

Given two points in the line, (-2 , -4) and (1 , 2), plug in the values to the formula for the slope.

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

m = (2 - -4)/(1 - -2)

From the figure given,

The angles must be either right angles, acute angles, or obtuse angle.

Acute Angle: An acute angle is an angle that measures less than 90 degrees. It is smaller than a right angle.

Obtuse Angle: An obtuse angle is an angle that measures greater than 90 degrees but less than 180 degrees. It is larger than a right angle.

2. The maximum height of the ball is of 34.18 meters, taking 2.6 seconds to reach it's height.

3. The ball will be in the air for 5.24 seconds.

The quadratic equation for the ball's height after t seconds is given by:

h(t) = -4.9t²+ 25.5t + 1.

Hence, after 3 seconds, the height is:

h(3) = -4.9(3)² + 25.5(3) + 1 = 33.4 meters.

The ball has a height of 33.4 meters after 3 seconds.

To find the maximum height of the ball, we have to find the vertex of the function.

A quadratic equation is modeled by:

The screen size of the HDTV is approximately 36.65 inches.

Here,

The screen aspect ratio of a high-definition television is 16:9, which means the width is 16 units and the height is 9 units.

We are given that the width of the HDTV is 41 inches.

To find the screen size, we can use the Pythagorean theorem, which states that the square of the hypotenuse (the diagonal distance across the screen) is equal to the sum of the squares of the other two sides (width and height).

Let's assume the height is h inches.

Using the Pythagorean theorem, we have:

[tex](41^2) = (16^2) + (9^2) + (h^2)[/tex]

Simplifying this equation, we get:

[tex]1681 = 256 + 81 + h^2\\1681 = 337 + h^2\\h^2 = 1681 - 337\\h^2 = 1344\\[/tex]

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we exists adding are factors of the product because the product exists divisible by them.

By eliminating the common variables, one may get the components of the equation x²y³ - 11x²y + 6y² - 66.

x²y³ - 11x²y + 6y² - 66

Take out the common from the first two terms.

⇒ x²y(y² - 11) ..........(1)

Take out common in the last two terms.

⇒ 6 (y² - 11) ..........(2)

Adding both the equations, (1) and (2) then

[x²y(y² - 11)] + [6 (y² - 11)] = x²y(y² - 11) + 6(y² - 11)
