Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
Suppose f(x) = x2 and g(x) = Which statement best compares the graph of g(x) with the graph of f(x)?
Answer:
g(x) is horizontally stretched by a factor of 1/5
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
[tex]g(x) = (\frac{x}{5})^2[/tex]
Require
Determine the relationship between f(x) and g(x)
[tex]f(x) = x^2[/tex]
[tex]g(x) = (\frac{x}{5})^2[/tex]
Express g(x) in terms of f(x)
[tex]g(x)=f(\frac{x}{5})[/tex]
This can further be simplified as:
[tex]g(x)=f(\frac{1}{5}x)[/tex]
When a function is represented as:
[tex]g(x) = f(cx)[/tex]
Where c < 1,
Then the type of translation is a horizontal stretch (stretch in the x direction)
By comparison: [tex]g(x) = f(cx)[/tex] and [tex]g(x)=f(\frac{1}{5}x)[/tex]
[tex]c = \frac{1}{5}[/tex]
This means that: g(x) is horizontally stretched by a factor of 1/5

Please help!!!!!!!! With explanation!!!!!
Answer:
a = 72° b = 88°
Step-by-step explanation:
We know in the cyclic quadrilateral opposite angles are supplementary so
a + 108° = 180° { being opposite angles of cyclic quadrilateral }
a = 180° - 108°
a = 72°
b + 92° = 180° { being opposite angles of cyclic quadrilateral }
b = 180° - 92°
b = 88°
Each pair of triangles is similar Find the value of x
Answer:
x = 7
Step-by-step explanation:
You need to figure which sides correspond and set up the proportions
Labeling the vertices of the triangles would help you.
I did that and found that 5x - 15 ↔ 10 since both of those sides are opposite the 42° angles and 36 ↔ 18
So [tex]\frac{5x - 15}{10} = \frac{36}{18\\}[/tex]
18(5x - 15) = 10(36)
90x - 270 = 360
90x = 630
x = 7

Oliver expects that the number of visitors to a museum(y) is related to the daily rainfall in mm(x). He plots a scatter plot and determines the equation for the line of best fit: y=14.1x+62.0 What is the expected number of visitors when the daily rainfall is 20 mm? Give your answer to the nearest integer.
Answer:
344 visitors
Step-by-step explanation:
Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as
y=14.1x+62.0
when the daily rainfall is 20 mm, the number of visitors
y = 14.1(20) + 62
= 282 + 62
= 344
It means that the expected number of visitors is 344 persons (to the nearest integer).
which figure is a translation of Figure A? explain. A translation, or slide, is a transformation that moves every point of a figure the same distance & the same direction.
Answer:
Figure B
Step-by-step explanation:
A translation does not "flip" the position of the pre-image. Figure C is a reflection of figure A.
A translation would "slide" the figure into a new position without mirroring nor rotating it.
Figure B should be the translation of Figure A.
Hope this helps.
Figure B is the translation of figure A by 2 units up.
What is the transformation of the graph?If a graph is translated and rotates by any amount either in x and y direction then it will be transfomation of the graph.
For example transformation of graph f(x) by 2 units down.
The new resultant graph could be only translated or rotated or both.
Given figure A
If we look at C then the face of this is towards the right but in figure A the face is towards the left.
So it means C will translate + rotation of graph A it will not be pure translation.
In figure B it is clear that it is a translation of figure A by 2 units upward.
Hence "Figure B is the translation of figure A by 2 units up".

Solve d=rt for r thanks!!!!
Answer:
Step-by-step explanation:
So you know that distance = rate x time.
9 miles in 1.5 hours
In this case, you know the time (1.5 hours) and the distance (9 miles)
(You can ignore the rest of the chart since the question is just about running.)
What's missing is the rate (r) at which you ran. (Think of it as speed...)
If r x t = d, that means that d ÷ t = r
So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...
6
So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!
What is the measure of ∠BCE, in degrees, in the figure shown?
Answer:
25 degrees
Step-by-step explanation:
So a triangles angels equal 180 degrees
So for angel ECD 180 - (15+90) = 75
Straight lines also always equal to 180 degrees so
180 - (80+75) = 25
Measure of ∠BCE = 25° .
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.
Given, In figure,
∠CED = 15°
∠EDC = 90°
∠BCA = 80°.
In triangle ECD
Sum of all interior angles of a triangle is 180°
∠ECD +∠CED +∠EDC = 180°
∠ECD + 15° + 90° = 180°
∠ECD = 180° - 105°
∠ECD = 75°
Now,
∠BCA,∠BCE and∠ECD are at point C on line AD.
Sum of all angles made at one point of line is 180°.
∠BCA +∠BCE +∠ECD = 180°
80° + ∠BCE + 75° = 180°
∠BCE = 180° - 155°
∠BCE = 25°
Hence, 25° is measure of ∠BCE.

What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?
Answer:
The answer is
[tex]y = - 7[/tex]
Answer:
y = -7
Step-by-step explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7

Mason pulled his hamstring while at track practice and received an MRI. His medical bills totaled
$1,200. How much would he have to make in order to pay his bills if he did not use an FSA or HSA?
Answer:
a minimum of $1,200
Step-by-step explanation:
The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.
