Answer:
1.53x10^8
Step-by-step explanation:
3.4 x 4.5 = 15.3 = 1.53x10
10^4 x 10^3 = 10^7
1.53x10x10^7 = 1.53x10^8
What is the circumference of the circle whose equation is (x − 9)2 + (y − 3)2 = 64?
Answer:
C = 16pi or ≈50.24 units
Step-by-step explanation:
(x − 9)^2 + (y − 3)^2 = 64
This equation is in the form
(x-h)^2 + (y-k)^2 = r^2
The radius is 8
The circumference is given by
C = 2*pi*r
C = 2*pi*8
C = 16 pi
Using 3.14 as an approximation for pi
C = 16(3.14)
C ≈50.24
Heather is conducting a study on music and memory. She plays different types of music while students memorize lists of words, then tests them on their retention after 1 hour, 1 day, and 1 week. In this example, which is the independent variable
Step-by-step explanation:
The independent variable is the one that we change, and because we are changing the genre, the independent variable is the different types of music.
The variable we can change is known as an independent variable, and since we are changing the style, the independent variable is the various musical forms.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given Heather is researching the relationship between music and memory as a result. Students learn word lists while listening to various music styles, and she analyzes their memory after an hour, a day, and a week.
A variable that is independent is exactly what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to measure.
Thus, the variable we can change is known as an independent variable, and since we are changing the style, the independent variable is the various musical forms.

Angles are not drawn to scale
Answer:
40 degrees
Step-by-step explanation:
Supplementary angles are a pair of angles that add up to 180 degrees
Since ABD and DBC are supplementary, you can make the equation:

[tex]\bf \large \implies \: \: x \: + \: 140 \degree \: = \: 180 \degree[/tex]
[tex]\bf \large \implies \: \: x \: = \: 180 \degree - \: 140 \degree[/tex]

To justify the area of a circle, the argument Yvonne wants to use = The dissection argument
The shape to which the reassembled figure tends to approximate = A parallelogram
Description of the of the reassembled figure
The horizontal parallel sides of the parallelogram formed = The arcs of the circle
The other pair of parallel sides = The radius of the circle
The best values of the characteristics of the parallelogram given in the table are therefore found as follows;
(a) The base of the parallelogram = (1/2) the total sum of the arcs in a circle = (1/2) the circumference of the circle = π·r
∴ The base of the parallelogram = π·r
(b) The height of the parallelogram = The perpendicular distance from the tip of one of the sectors to the midpoint of the arc of the sector = The radius of the circle = r
∴ The height of the parallelogram = r
(c) The area of the parallelogram, A = The sum of the area of the sectors
A = (n × θ/360) × π·r²
Where;
n × θ = 360°
Therefore;
A = (n × θ/360) × π·r² = (360/360) × π·r² = π·r²
We have;
The area of the parallelogram, A = π·r²
The table showing the best value of each characteristics of the parallelogram is therefore presented as follows;

Answer:
[tex](x-6)(x+6)[/tex]
Step-by-step explanation:
In order to simplify this equation, one must use the quadratic factoring patterns. These patterns are as follows:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
This pattern works because, if one is to distribute the terms in the parenthesis by multiplying each term in one of the parenthesis by every term in the other, the result is the original equation:
[tex](a-b)(a+b)\\\\=(a)(a)+(a)(-b)+(a)(b)+(b)(-b)\\\\=a^2-ab+ab-b^2\\\\=a^2-b^2[/tex]
One can apply this pattern to the given equation, remember (6) times itself equals (36). Therefore, one can state the following: ([tex]36=6^2[/tex]), thus one can apply it to the given equation:
[tex]x^2-36\\\\=x^2-6^2\\\\=(x-6)(x+6)[/tex]
A rectangular bathroom mirror has a perimeter of 22 feet. Its area is 18 square feet. What are the dimensions of the mirror?
Answer:
The dimensions of the mirror is 9 feet and 2 feet
Step-by-step explanation:
Keep in mind that the area and perimeter of a rectangle is:
Area - length x width
Perimeter - 2 (l + w)
List the factors of 18 (the area of the mirror):
1, 2, 3, 6, 9, 18
POSSIBLE DIMENSIONS OF MIRROR:
1 ft and 18 ft
Area = 18 ft^2
Perimeter = 38 feet
2 ft and 9 ft
Area = 18 ft^2
Perimeter = 22 feet
3 ft and 6 ft
Perimeter = 18 feet
The rectangle with dimensions 2 feet and 9 feet corresponds with the area and perimeter of the mirror mentioned. So those are the correct dimensions.

how long should the ladder be if they want to use all the canle they have? use the law of sines to find the length.
Answer: L = 36 feet approximately
The more accurate value is 35.9547644 feet, but this approximate value isn't exact either.
============================================================
Explanation:
Ignore the vertical line and any byproducts of it.
Refer to the diagram below. Note that the 95 degree angle is from 15+80 = 95.
We can use the law of sines like so
sin(A)/a = sin(B)/b
sin(75)/200 = sin(10)/L
L*sin(75) = 200*sin(10)
L = 200*sin(10)/sin(75)
L = 35.9547644 which is approximate.
This rounds to roughly 36 feet when rounding to the nearest whole number.
Side note: We never use angle C = 95, and its opposite side.

The function g(x) = x2 is transformed to obtain function h:
h(x) = g(x − 3).
Which statement describes how the graph of h is different from the graph of g?
A.
The graph of h is the graph of g vertically shifted up 3 units.
B.
The graph of h is the graph of g horizontally shifted right 3 units.
C.
The graph of h is the graph of g horizontally shifted left 3 units.
D.
The graph of h is the graph of g vertically shifted down 3 units.
Answer:
B
Step-by-step explanation:
Given g(x) then g(x + a) is a horizontal translation of g(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
h(x) = g(x - 3) = (x - 3)² with a < 0
The graph of h(x) is the graph of g(x) horizontally shifted right 3 units

A survey was taken of children between the ages of 3 and 7. Let A be the event that the person has 2 siblings, and let B be the event that the person does not have a pet.
Which statement is true about whether A and B are independent events?
A and B are independent events because P(A∣B) = P(A) = 0.18.
A and B are independent events because P(A∣B) = P(A) = 0.4.
A and B are not independent events because P(A∣B) = 0.4 and P(A) = 0.18.
A and B are not independent events because P(A∣B) = 0.18 and P(A) = 0.4.
Answer: A and B are not independent events because P(A∣B) = 0.18 and P(A) = 0.4.
Step-by-step explanation:
They are not independent events because if they were P(A∣B) and P(A) would be equal.
In a Quadrilateral, two of the angles each have a measure of 110°, and the measure of the third angle is 90°. What is the measure of the remaining angle?
Answer:
50°
Step-by-step explanation:
The total measurement of the sum of the interior angles is 360.
It is given that two of the angles has a measurement of 110. The third angle has a measurement of 90. Let the unknown measurement angle = x. Set the equation:
110 + 110 + 90 + x = 360
Combine like terms:
(110 + 110 + 90) + x = 360
310 + x = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 310 from both sides:
310 (-310) + x = 360 (-310)
x = 360 - 310
x = 50
50° is the measurement of the remaining angle.
