The difference is 7.76 × 10³ in scientific notation.
What is scientific notation?
Scientific notation is a way of expressing a number as a number between 1 and to multiplied by a power of 10.
We can perform the subtraction in the usual way, using the fact that the numbers are already in scientific notation:
(8.4 × 10³) − (6.4 × 10²) = 8.4 × 1000 − 6.4 × 100
= 8400 − 640
= 7760
To write this in scientific notation, we can express the result as a number between 1 and 10 multiplied by an appropriate power of 10. In this case, we can write:
7760 = 7.76 × 10³
Therefore, the difference is 7.76 × 10³ in scientific notation.

g(x).
Answer:
The formula for the function g(x) obtained when the graph of f(x) = √x is shifted up 1 unit and to the left 6 units is g(x) = √(x + 6) + 1.
Step-by-step explanation:
To obtain the formula for the function g(x) when the graph of f(x) = √x is shifted up 1 unit and to the left 6 units, we can use the following transformations:
A vertical shift up by 1 unit is represented by adding 1 to the function: f(x) + 1
A horizontal shift to the left by 6 units is represented by replacing x with (x + 6): f(x + 6)
Therefore, the formula for the function g(x) is:
g(x) = f(x + 6) + 1
Substituting the expression for f(x), we get:
g(x) = √(x + 6) + 1
So, the formula for the function g(x) obtained when the graph of f(x) = √x is shifted up 1 unit and to the left 6 units is g(x) = √(x + 6) + 1.

Plot function / on the graph.
h(x)= {-4, x<-3
x+5, >-3
Answer:
I do not have access to drawing tools. However, I can describe how to plot the function on a graph.
To plot the function h(x) = {-4, x < -3 and x+5, x > -3, you would start by drawing the x-y axes on a coordinate plane. Then, you would mark a point at x=-3 on the x-axis. At this point, the value of h(x) changes from -4 to x+5. So, you would draw a solid dot at (-3, 2) on the graph.
Next, you would draw a horizontal line at y=-4 to the left of x=-3, indicating that h(x) is always equal to -4 for x values less than -3.
Finally, you would draw a diagonal line starting from the dot at (-3, 2) and continuing to the right. This line represents the equation x+5 for x values greater than -3.
The resulting graph should have a horizontal line at y=-4 to the left of x=-3, a solid dot at (-3, 2), and a diagonal line extending to the right from the dot.

Explain why 200,000 square kilometers is a good estimate forthe area of South Dakota.
Answer:
Step-by-step explanation:
200,000 square kilometers is a good estimate for the area of South Dakota because the actual area of South Dakota is approximately 199,729 square kilometers according to the United States Geological Survey (USGS).
This means that the estimate is only off by about 0.1% of the actual area. This level of accuracy is generally considered to be very good for an estimate, especially when dealing with large areas like states or countries.
Additionally, 200,000 square kilometers is a round number and easy to remember, making it a useful estimate in contexts where a precise value is not necessary. It also allows for quick comparisons with other areas or states that may be roughly similar in size.
Overall, 200,000 square kilometers is a good estimate for the area of South Dakota because it is reasonably close to the actual value, easy to remember, and useful for rough comparisons with other areas.
ALSO:
South Dakota is approximately 383 miles long (east to west) and 237 miles wide (north to south).
It has the approximate shape of a rectangle, its Area = (Base x Height)= (383 x 237)= 90,771.00 miles ^2 which are 235,095.81 Km^2. So by this geometric reasoning we can have a correct approximation of the area of South Dakota.
A recriprocal function has a vertical asymptote located at x = -2 and a horizontal asymptote located at y = 5. Write an equation that could represent this function.
Answer:
A reciprocal function can be written in the form of f(x) = a / (x-h) + k, where a is a constant, h is the x-value of the vertical asymptote, and k is the y-value of the horizontal asymptote.
Given that the vertical asymptote is located at x = -2 and the horizontal asymptote is located at y = 5, we can write:
f(x) = a / (x - (-2)) + 5
Simplifying this expression, we get:
f(x) = a / (x + 2) + 5
Therefore, an equation that could represent this reciprocal function is:
f(x) = a / (x + 2) + 5

Gene owns 1,200 shares of XYX Corporation. The company instated a 1 for 10 reverse stock split on November 7. The pre split market price per share was $1.20.
Answer:
After the reverse stock split, Gene will own 120 shares of XYX Corporation.
To calculate the post-split market price per share, we can start by finding the total value of Gene's shares before the split:
Total value before split = 1,200 shares * $1.20 per share = $1,440
Since the reverse stock split is 1 for 10, the total number of shares outstanding will be reduced by a factor of 10, and the price per share will be increased by a factor of 10:
Total value after split = 120 shares * $12.00 per share = $1,440
Therefore, the post-split market price per share is $12.00.

If the ratio of x:8=21:24, what is the value of x?
Answer:
See below.
Step-by-step explanation:
For this problem, we are asked for the value of x.
Let's use a Proportion to identify x.
What is a Proportion?A Proportion is a comparison of two equivalent fractions, or ratios.
An example of a proportion can be; [tex]\frac{x}{16} =\frac{16}{32}[/tex], where the value of x is 8.
For this example, we can find x by dividing the Numerator and Denominator by 2.
Let's use the example as a guide for our problem.
We can set up our problem as a ratio, or a fraction. Both represent the same data.
[tex]\frac{x}{8} = \frac{21}{24}[/tex]
We should know that 24 is 3 times bigger than 8, hence we should divide both the Numerator and Denominator by 8.
[tex]\frac{21 \div 8}{24 \div 8} = \frac{7 \ (x)}{8}[/tex]
The value of x is 7.
Answer: x = 7
Step-by-step explanation:
Given:
x:8 = 21:24
Rewrite as fractions:
[tex]\displaystyle \frac{x}{8} =\frac{21}{24}[/tex]
Cross-multiply:
x * 24 = 8 * 21
24x = 168
Divide both sides of the equation by 24:
x = 7

Here are several y intercept instances. So we obtain y = 5(0)2 + 2 = 2 when we replace x = 0, so y-intercept of y Equal 5x2 + 2 is (0, 2). Because we obtain y = -5e0 = -5 when we try substituting x = 0, this same y-intercept of y Equal -5ex is (0, -5).
Y-intercept: Is it 0 or 1?
The point where a straight line intersects the X-axis is known as the Y interception. In the picture above, the line intersects the Value of y at 1. The point is shown by and the value of the Variable y is 1. (0,1). Remember that for the y-intercept, the point's such and such is always zero.

The radical expression (6–√4)3 written in exponential form is 612.
What is expression?Expression is a term used to describe the process of making clear or conveying one's thoughts, ideas, and feelings. It is a way of communicating with others and expressing oneself in a meaningful and effective manner. Expression can be done through verbal and non-verbal communication, including writing, art, music, dance, and other creative outlets. It can also be used to express emotions such as joy, sadness, fear, anger, and love. Expression is essential to healthy communication and can be a powerful tool for self-expression, personal growth, and development.
This is because raising a number to an exponent is the same as multiplying that number by itself the number of times specified by the exponent. In this case, the base number is 6, and the exponent is 12. When a number is multiplied by itself 12 times, it is referred to as an exponential expression. To convert the radical expression to an exponential expression, the radical needs to be converted to an exponent. The radical of 4 is 2, so the exponent is 12. This results in the answer 612.
