The order of the numbers from lowest to highest is 4.68 × 10⁻⁶, 8.34 × 10⁻², 1.2 × 10⁷, 3.24 × 10⁹ and 5.48 × 10⁹
What is the order of the numbers from lowest to highest?The given numbers are expressed in standard form. Standard form is a way of writing numbers as a power 10 e.g 100 = 1 × 10² and 0.01 = 1 × 10⁻².
So converting the numbers back to ordinary numbers will be useful.
To do this, we will multiply or divide the powers of 10 with the decimal numbers.
We will multiply if the power is positive e.g 2.4 x 10² = 2.4 x 100 = 240 and divide if the power is negative 2.4 x 10⁻² = 2.4/100 = 0.024
3.24 × 10⁹ = 3.24 x 1000,000,000 = 3240000000
4.68 × 10⁻⁶ = 4.68 / 1000000 = 0.00000468
5.48 × 10⁹ = 5480000000
8.34 × 10⁻² = 8.34/100 = 0.0834
1.2 × 10⁷ = 12000000
Therefore, arranging from lowest to highest. We have:
4.68 × 10⁻⁶, 8.34 × 10⁻², 1.2 × 10⁷, 3.24 × 10⁹ and 5.48 × 10⁹

quarter. 9.78. 8.95
dime. 4.09. 3.91
nickel. 9.53. 8.09
penny. 1.67. 1.66
Answers
The dime has a cost in 2014 that is less than 0.95 times the cost in 2007.
To solve this problem by finding out the ratio. We can solve this problem by following a few steps.
According to the question, the cost in 2014 is less than 0.95 times the cost in 2007.
So the ratio is 1: 0.95. Which can be written as, 1/ 0.95 = 100/95 = 20/19 = 20: 19.
Now, we have to find among all those coins which follow the trend of 20: 19.
For the quarter, the ratio is 9.78: 8.95 = 9.78 / 8.95 ≠ 20 : 19For the dime, the ratio is 4.09: 3.91 = 4.09/3.91 ≈20: 19For the nickel, the ratio is = 9.53: 8.09= 9.53. 8.09 ≠ 20: 19For the penny, the ratio is = 1.67: 1.66 = 1.67/1.66 ≠ 20: 19Here only the price of a dime has declined 0.95 times.

The equation of the quadratic equation is P(x) = x² + 23/4x - 21/4
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the quadratic equation?The given parameters are
Zeros = -7 and 3/4
The sum of multiplicities of the quadratic equation must be equal to the degree.
This means that the multiplicity of the zeros -7 and 3/4 is 1
The equation of the quadratic equation is then calculated as
P(x) = (x - zero)^ multiplicity
So, we have
P(x) = (x + 7)(x -3/4)
Expand
P(x) = x² + 7x - 3/4x - 21/4
This gives
P(x) = x² + 23/4x - 21/4
Hence, the equation is P(x) = x² + 23/4x - 21/4

Answer:

If a circle has center located at (a, b) and radius of r, the equation of this circle is
(x - a)² + (y-b)² = r²

How to find equation of a line?The line passes through (-1, -1) and it is parallel to h(x) = -1x + 10
When lines are parallel, the slopes are the same.
Therefore, the equation of a line that passes through (-1, -1) and parallel to h(x) = -1x + 10 can be calculated as follows:
Hence,
y = mx + b

What is ratio?A ratio in mathematics demonstrates how many times one number is contained in another. For instance, the ratio of oranges to lemons in a dish of fruit is eight to six if there are eight oranges and six lemons present. Similarly, the ratio of oranges to the total amount of fruit is 8:14 while that of lemons to oranges is 6:8. A ratio is an ordered pair of numbers a and b, expressed as a / b, where b is not equal to 0. A percentage is an equation in which two ratios are made equal to one another. For instance, you could express the ratio as 1: 3 (one boy to three females), meaning that one in four of the population is male.
Nickel is equivalent to 0.05 dollars.
2 nickels are equivalent to (0.05 × 2) = 0.01 dollars.

11. Find the length of the missing side. 16 25 19
Answers
Answer:
x = 14.12
Explanation:
To find the missing side, we will use the cosine law:
[tex]c^2=a^2+b^2-2ab\cos (C)[/tex]Where a, b, and c are the length of the sides of the triangle and C is the measure of the angle formed by the sides a and b.
So, we can use the equation to find the angle formed by the side of length 35 and the side of length 44 (25 + 19 = 44). So, replacing a by 35, b by 44, and c by 16, we get:
[tex]16^2=35^2+44^2-2(35)(44)\cos (\theta)[/tex]Then, solving for θ, we get:
[tex]\begin{gathered} 256=1225+1936-3080\text{cos(}\theta) \\ 256=3161-3080\cos (\theta) \\ 256-3161=-3080\cos (\theta) \\ -2905=-3080\cos (\theta) \\ \frac{-2905}{-3080}=\cos (\theta) \\ 0.9432=\cos (\theta) \\ \cos ^{-1}(0.9432)=\theta \\ 19.41=\theta \end{gathered}[/tex]Now, we can calculate the length of the missing side, using the angle θ = 19.41°, the side with length 35 and the side with length 25 as:
[tex]x^2=35^2+25^2-2(35)(25)\cos (19.41)[/tex]Therefore, the value of x is:
[tex]\begin{gathered} x^2=1225+625-1650.56 \\ x^2=199.44 \\ x=\sqrt[]{199.44} \\ x=14.12 \end{gathered}[/tex]So, the length of the missing side is 14.12

what is mapping?
Any set, including all whole integers, all the points on a line, or all the objects inside a circle, can be mapped. A mapping of the set of all whole numbers onto the set of even numbers is defined by the expression "multiply by two," for instance. A rotation is an internal map of a plane or of all of space.
The vertices of ΔDEF are given by D(2,-4) - D E(1,-1) - E F(5, 1).
According to the rule defining a reflection across the line, y=x should be stated when reflecting a point across the line. Then, the x and y coordinates are switched as follows:
y(x, y) → (y, x)
Let's now use the aforementioned rule to finish mapping the vertices of DEF. Change the x and y coordinate locations as follows:
D(2, –4) gives (-4, 2)D'E(1, –1) gives (-1, 1)E'F(5, 1) gives (1, 5)F'The vertices of the ΔDEF are given by (-4, 2)D', (-1, 1)E' , (1, 5)F' through mapping.
