When numbers are very small or very large, it is convenient to either express the value in scientific notation and/or by using a prefix with the unit.
A pain-relieving pill has a mass of 0.005 g
g
. Express the pill’s mass in grams using scientific notation or in milligrams.
The scientific notation of Pill's mass 5 × 10⁻³ g.
And, In milligrams, The pill's mass is 5.0 milligram.
What is Scientific notation?Scientific notation is a way of writing a very large or very small numbers. For example; 230,000,000 can be written in scientific notation as 2.3 x 10⁸.
Given that;
A pain-relieving pill has a mass of 0.005 g.
Now, We can write the mass in scientific notation as;
⇒ 0.005 g
⇒ 5 × 10⁻³ grams
And, We can write the pill's mass in milligram as;
Since, 1 g = 1000 milligram
Hence, We get;
⇒ 0.005 g = 0.005 × 1,000 milligrams
= 5.0 milligrams.

After a 5% tax,a DVD costs $21.How much did it cost before the 5% tax was added?
Answer:
$20
Step-by-step explanation:
You want to know the pre-tax price if the price with 5% tax added is $21.
TaxThe added tax is 5% of the original amount (x), so the amount with tax added is ...
$21 = x + 0.05x = 1.05x
$21/1.05 = x = $20 . . . . . divide by the coefficient of x
The cost before tax was added was $20.
Step-by-step explanation:
Percentage left after the tax percentage is
100%-5%=95%
95% is equal to 95/100 = 0.95
therefore, the cost after tax divided by the percentage that is left after the tax percentage
costs after tax is 21 dollars which is

What is a function?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).
There are several types of functions in math. Some important types are:
Injective function or One to one function: When there is mapping for a range for each domain between two sets.
Surjective functions or Onto function: When there is more than one element mapped from domain to range.
Polynomial function: The function which consists of polynomials.
Inverse Functions: The function which can invert another function.
Now,
Given functions are f(x)=1-x^2 and

What do you add to 5 5/8 to make 7 as an improper fraction?
Answer: We need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅
PLEASEEEE GIVE BRANLIEST
Step-by-step explanation: To add 5 5/8 to a number to make 7 as an improper fraction, we need to convert 5 5/8 to an improper fraction.
To convert a mixed number to an improper fraction, we take the whole number, multiply it by the denominator of the fraction, and add the numerator. So, 5 5/8 becomes (5 x 8) + 5 / 8 = 40 + 5 / 8 = 45/8.
Now, we can add 45/8 and the number that we need to add to make 7 as an improper fraction.
45/8 + x = 7
To find x, we can subtract 45/8 from both sides of the equation:
x = 7 - 45/8
x = 1 7/8
So, we need to add 1 7/8 to 5 5/8 to make 7 as an improper fraction. ✅

what is angle ?In Euclidean geometry, an angle is a shape that is made up of two rays, known as the hood's sides, that meeting at a middle point known as the wall's apex. Two rays may combine to form an angle in the planes where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two photons or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, sometimes known as two sides of the angle, converge.

Write an equation of the line that passes through (1,2) and is perpendicular to the line y=1/3x+4
The line that cuts through (1, 2) and is perpendicular to (y = 1/3x + 4) has the equation (y = -3x + 5).
What is the equation of the line?A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.
On the y-axis, this value c is referred to as the intercept.
Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
y = 1/3x + 4 is the line that crosses (1,2) and is perpendicular to it.
To ascertain the equation of the line, utilize the procedures below:
Step 1: Two lines that are perpendicular to one another have the following slopes:
mm' = 1
Where the slopes of the lines are m and m'.
Step 2 - The line that is perpendicular to the line (y = 1/3x + 4) has the following slope:
1/3 * m' = -1
m' = -3
Step 3: The equation for a line passing through the points (1, 2) and having a slope of -3 is as follows:
(y - 2) = -(x - 1)

"Choice D" The dot plot with the outlier at 4 feet and data points condensed on the right from 5.5-7 feet is the correct dot plot.
Step-by-step explanation:
ExplanationA dot plot is a statistical chart consisting of data points plotted on a simple scale, typically using filled-in circles.
A skew represents the direction in which the data points follow.
A negative skew indicates that the majority of the data points fall on the left side of the scale. Ex: "The height of the sunflowers in feet decreases when less sunlight is given."A positive skew indicates that the majority of the data points fall on the right side of the scale. Ex: "The height of the sunflowers in feet increases when more sunlight is given."An outlier is a data point that "stands out" from other data points.
Answer BreakdownChoices A and B are skewed left because their data points lie on the left side of the number line. These data points display a decrease in the sunflowers' height. So they are automatically eliminated. Choice C is skewed right, however, it contains no outliers. All the data points are condensed evenly to one side. This answer is incorrect. Choice D is the correct answer. The data points lie on the right side of the scale. There is also one outlier present at 4 feet, separating it from the rest of the data points.Please let me know if this helped!!!

Part (b)As the given sequence has a constant difference of 10, it is an arithmetic sequence.
Part (c)[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]
The common difference is 10. Therefore:
d = 10To find the first term, a, substitute the value of d and one of the terms into the formula:
[tex]\begin{aligned}\implies a_4=a+(4-1)(10)&=33\\a+3(10)&=33\\a+30&=33\\&a=3\end{aligned}[/tex]
Therefore, to write an equation for the given arithmetic sequence, substitute the found values of a and d into the formula:
