Answer:

x = ±20

Step-by-step explanation:

x² - 1 = 399

x² = 400

x = ±√(400)

x = ±20

Hello !

Answer:

\(\boxed{\sf x=\pm 20}\)

Step-by-step explanation:

We want to solve the following equation :

\(x^2-1=399\)

Let's add 1 to both sides :

\(x^2-1+1=399+1\\x^2=400\)

We know that if \(x^2=a\) (assuming \(a\geq 0\)), then \(x=\pm\sqrt a\).

Let's apply this to our equation :

\(\sf x=\pm \sqrt {400}\\x=20\ \sf{or}\ x=-20\)

This equation has two solutions: x = 20 and x = -20

Have a nice day !

Dilation does not maintain congruence.

What is transformation?

In arithmetic, a transformation may be a operate f, typically with some geometrical underpinning, that maps a collection X to itself, i.e. f: X → X.

Main Body:

The options are:

a. dilation

b. rotation

c. reflection

d. translation

Congruent figures are the same shape and the same size.  The only choice that involves changing the size of a figure is letter a) dilation and as a result, creates two figures that are NOT congruent.  

The other three choices merely "move" a shape to a new location (i.e. rotated, translated, or reflected) and result in a congruent figure.

Hence ,dilation does not maintain congruence.

F(x,y) = x² + 3y cannot satisfy the definition of uniform continuity on the whole plane.

F(x,y) = x² + 3y is a polynomial function, which means it is continuous on the whole plane, but that does not mean that it is uniformly continuous on the whole plane.

For F(x,y) = x² + 3y to be uniformly continuous, we need to prove that it satisfies the definition of uniform continuity, which states that for every ε > 0, there exists a δ > 0 such that if (x1,y1) and (x2,y2) are points in the plane that satisfy

||(x1,y1) - (x2,y2)|| < δ,

then |F(x1,y1) - F(x2,y2)| < ε.

In other words, for any two points that are "close" to each other (i.e., their distance is less than δ), the difference between their function values is also "small" (i.e., less than ε).

This implies that there exist two points in the plane that are "close" to each other, but their function values are "far apart," which is a characteristic of functions that are not uniformly continuous.

Therefore, F(x,y) = x² + 3y cannot satisfy the definition of uniform continuity on the whole plane.

A multiplier of 1.2 means the value is multiplied or increased by a factor of 1.2.

A multiplier is a term used to represent a factor by which a value is multiplied or increased. It is a numeric value that indicates the extent of the increase or expansion of a given quantity. Multiplication by a multiplier results in scaling or changing the magnitude of the original value.

A multiplier of 1.2 indicates that a value will be increased by 20% or multiplied by a factor of 1.2. This means that when the multiplier is applied to the original value, the resulting value will be 1.2 times the original.

Less than half of the surveyed internet users have posted photos or videos online. To determine if less than half of internet users have posted photos or videos online based on the poll, we can follow these steps:

1. Calculate the proportion of users surveyed who have posted photos or videos online.
2. Compare the proportion to 0.5 (which represents half).

Step 1: Calculate the proportion
The poll surveyed 1,765 internet users, and 865 of them posted a photo or video online. To calculate the proportion, we can divide the number of users who posted (865) by the total number of users surveyed (1,765):

Proportion = 865 / 1,765 ≈ 0.49

Step 2: Compare the proportion to 0.5
Since 0.49 is less than 0.5, it appears that less than half of the surveyed internet users have posted photos or videos online.

However, we cannot conclude that this is true for all internet users, as the poll surveyed a limited sample size of 1,765 users. A larger, more representative sample may be needed to draw a more accurate conclusion.

The probability of four successes in this binomial distribution is 0.2668, or approximately 26.68%. This means that if we conduct 9 trials with a 20% chance of success on each trial, we would expect to get exactly 4 successes with a probability of 0.2668.

To find the probability of four successes in a binomial random variable, we use the formula for the probability mass function (PMF) of a binomial distribution:

P(X=k) = (n choose k) * \(p^k\) * (1-p)\(^(n-k)\)

where n is the number of trials, p is the probability of success on each trial, k is the number of successes, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k successes from n trials.

In this case, we have n = 9, p = 0.2, and k = 4. So, we can plug these values into the formula:

P(X=4) = (9 choose 4) * 0.\(2^4\) * (1-0.2)\(^(9-4)\)

= (126) * 0.\(2^4\) * 0\(.8^5\)

= 0.2668

Therefore, the probability of four successes in this binomial distribution is 0.2668, or approximately 26.68%. This means that if we conduct 9 trials with a 20% chance of success on each trial, we would expect to get exactly 4 successes with a probability of 0.2668.

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

The midpoint is the point on the middle of the line that is equally distant from the two points if a line is drawn connecting the two points. The midpoint is the point B that lies halfway between any two points, let's say A and C.

The middle value in a group of numbers that are arranged numerically is the median. It is also referred to as the midpoint because it represents the centre of the data collection. You can expect that half of the values on your list will be lower and half will be higher than the median.

In order to get coordinates of D such that △ABC ≅ △ADC, the distance between the point A and the point D should be the same that the distance from the point A to the point B. Therefore, we just need to reflect the point B over the point A.

Reflecting the point B over the point A give us a point that is located 4 units right and 8 units down from the point B.

Thus, the coordinates of the point D are: (1,-3)
