What is 763 thousandths in scientific notation?
Answer: [tex]7.63\times10^{-1}[/tex]
Step-by-step explanation:
The scientific notation is a technique to express a very large or a very small number in the product of a decimal form of number [commonly between 1 and 10] and powers of ten.We know that one thousandth is written as :
[tex]\text{One thousandth}=\frac{1}{1000}[/tex]
Therefore, 763 thousandths can be written as :
[tex]\text{ 763 thousandths}=\frac{763}{1000}=\frac{7.63}{10}[/tex]
In Scientific notation:
[tex]\frac{7.63}{100}=763\times10^{-1}......[\text{ By law of exponents }](\frac{1}{a^n}=a^{-n})[/tex]
The number [tex]763\text{ thousandths}[/tex] in scientific notation is [tex]\boxed{\bf 7.63\times 10^{-1}}[/tex].
Further Explanation:
The scientific notation is a technique which is used to express a very large or a very small number in the product of a decimal form of number [commonly between 1 and 10] and a power of ten.
It can easily simplify an arithmetic operation and in a scientific calculator it is known as SCI display mode.
In scientific notation, all the numbers can be written as follows:
[tex]\boxed{x\times 10^{y}}[/tex]
Here, [tex]y[/tex] is an exponent integer and [tex]x[/tex] is the real number. The integer [tex]y[/tex] is the order of the magnitude and [tex]x[/tex] is called the mantissa (fractional part of the number).
As we know that one thousandths in mathematical form can be written as follows:
[tex]\boxed{1\text{ thousandths}=\dfrac{1}{1000}}[/tex]
Therefore, the number [tex]763\text{ thousandths}[/tex] in mathematical form is written as follows:
[tex]\boxed{\begin{aligned}763\text{ thousandths}&=\dfrac{763}{1000}\\&=\dfrac{7.63}{10}\end{aligned}}[/tex]
So, in scientific notation the number [tex]763\text{ thousandths}[/tex] is written as follows:
[tex]\boxed{\dfrac{7.63}{10}=7.63\times 10^{-1}}[/tex]
Therefore, the number [tex]763\text{ thousandths}[/tex] in scientific notation is expressed as [tex]\boxed{\bf 7.63\times 10^{-1}}[/tex].

Identify the percent of change as an increase or a decrease. 68 miles to 42.5 miles
Final answer:
The distance changing from 68 miles to 42.5 miles represents a 37.5% decrease, calculated using the percent change formula.
Explanation:
The question involves calculating the percent of change when the distance changes from 68 miles to 42.5 miles. To find the percent of change, we use the formula: Percent Change = ((New Value - Original Value) / Original Value) x 100%. Here, the original value is 68 miles and the new value is 42.5 miles.
Plugging in the values, we get: Percent Change = ((42.5 - 68) / 68) x 100% = (-25.5 / 68) x 100% ≈ -37.5%. Because the result is negative, this indicates a decrease in the distance traveled.
Therefore, the distance changing from 68 miles to 42.5 miles represents a 37.5% decrease.

If x denotes the length of a side of an equilateral triangle, express the area of the triangle as a function of x.
Using the concept of an equilateral triangle, it is found that it's area is given by:
[tex]A = \frac{\sqrt{3}}{4}x^2[/tex]
In an equilateral triangle, all sides have the same length.The area of a triangle is one half of the base multiplied by the height.For the equilateral triangle in this problem, the base is x, that is, [tex]b = x[/tex]The height is one side of a right triangle, in which the other side is half the base and the other is the base, thus, applying the Pythagorean Theorem:
[tex]h^2 + (\frac{x}{2})^2 = x^2[/tex]
[tex]h^2 + \frac{x^2}{4} = x^2[/tex]
[tex]h^2 = \frac{3x^2}{4}[/tex]
[tex]h = \sqrt{\frac{3x^2}{4}}[/tex]
[tex]h = \frac{\sqrt{3}}{2}x[/tex]
Then, the area is:
[tex]A = \frac{bh}{2} = \frac{1}{2} \times x \times \frac{\sqrt{3}}{2}x = \frac{\sqrt{3}}{4}x^2[/tex]

Given that (-2,-5) is on the graph of f(x), find the corresponding point for the function f(-2/3x).
The corresponding point for the function f(-2/3x) given the point (-2,-5) on the graph of f(x) is (3,-5), where the x-coordinate is transformed by multiplying -2 by -3/2 and the y-coordinate remains unchanged.
The question asks about finding a corresponding point for the function f(-2/3x) given that the point (-2,-5) is on the graph of the original function f(x). To find the corresponding point, we need to apply the transformation to the x-coordinate of the given point. Since the function is f(-2/3x), this represents a horizontal stretch by the reciprocal of -2/3, which is -3/2. Therefore, we multiply the x-coordinate of the given point by -3/2.
Let's calculate this step by step:
Start with the original point (-2,-5).Apply the transformation to the x-coordinate: -2 multiplied by -3/2 equals 3.The y-coordinate remains unchanged because the transformation applies only to the x-coordinate.1)Solve for x.

Which of the following is equivalent to the expression (9x^2y^3)(12x^-3y^5)( 2xy)? 23x^-5y^8 216^9 -x^-6y^8
Final answer:
The expression (9x^2y^3)(12x^-3y^5)(2xy) simplifies to 216y^9 by multiplying the coefficients and adding the exponents of like bases.
Explanation:
The student's question involves simplifying an algebraic expression by using the properties of exponents. When we multiply expressions with the same base, we add the exponents. The given expression (9x2y3)(12x-3y5)(2xy) can be simplified by multiplying the coefficients (numerical values) and adding the exponents of like bases separately.
Multiply the coefficients: 9 * 12 * 2 = 216
Add the exponents for x: 2 + (-3) + 1 = 0 (x's cancel out because x0 = 1)
Add the exponents for y: 3 + 5 + 1 = 9
Thus, the simplified expression is 216y9.

The solution of the given system of linear equation would be x = 1, y = 1, and z = 0.
What is a linear equation?A linear equation is one in which the greatest power of the variable is always one.
The given system of linear equation as:
-2x+2y+3z=0 ...(i)
-2x-y+z=-3 ...(ii)
2x+3y+3z=5 ...(iii)
Adding the third equation to the (i) and (ii), we get

At a recent boat show, Boater's Paradis sold five more boats than Pelican Marine sold. If together they sold 33 boats, how many were sold by each company?
In this mathematics problem about boat sales, Pelican Marine sold 14 boats and Boater's Paradis sold 19 boats. This conclusion was achieved by forming and solving a simple algebraic equation based on the provided problem information.
Explanation:To solve this problem, let's visualize it first. Pelican Marine sold a certain number of boats, and Boater's Paradis sold 5 more than that. If we call the number of boats sold by Pelican Marine as x, and adding Boater's Paradis' sales (x + 5), together they sold 33 boats. So we form the equation as x + (x+5) = 33.
Solving that equation, we will get 2x + 5 = 33, then simplify it to 2x = 28 after subtracting 5 from both sides. Finally, we divide both sides by 2 we get x = 14.
So, Pelican Marine sold 14 boats and Boater's Paradis sold 19 boats (14 boats Pelican Marine sold plus an additional 5 Boater's Paradis sold).

Find all values of x in the interval [0, 2π] that satisfy the equation. (enter your answers as a comma-separated list.) 3|tan(x)| = 3 g study
The values of x in the interval [0, 2π] that satisfy the equation 3|tan(x)| = 3 are π/4, 3π/4, 5π/4, and 7π/4.
Explanation:The given equation is 3|tan(x)| = 3. This means the absolute value of the tangent of x times 3 is equal to 3. We can remove the 3 from both sides to simplify to |tan(x)| = 1. The absolute value operator denotes the non-negative value of a number. So, we need to find the values of x such that tan(x) equals 1 or -1.

how long would it take a ball dropped from a 100 ft building to hit the ground
Final answer:
To find the time it takes for a ball to fall from a 100 ft building, convert the height to meters and use the free fall motion formula. Solving s = (1/2)gt² for time, it takes approximately 2.5 seconds for the ball to hit the ground.
Explanation:
To determine how long it would take for a ball dropped from a 100 ft building to hit the ground, we can use the formula for the free fall motion under the influence of gravity, assuming air resistance is negligible. The formula is s = (1/2)gt², where s is the distance fallen, g is the acceleration due to gravity (approximately 9.8 m/s², but we will need to convert it to feet per second squared for this problem), and t is the time in seconds.
First, convert 100 feet to meters because the standard unit of gravity is in meters per second squared. There are approximately 3.281 feet in a meter, so 100 feet is roughly 30.48 meters.
Now apply the formula and solve for t:
Convert acceleration due to gravity to feet: 9.8 m/s² is approximately 32.2 ft/s².
Use the formula: 100 = (1/2)(32.2)t².
Solve for t: t² = 100 / 16.1.
Find t: t = √(100 / 16.1).
Calculate t: t ≈ 2.49 seconds.
Therefore, it would take approximately 2.5 seconds for the ball to hit the ground.
