0.009
Step-by-step explanation:
So 9/1000 can be written as 0.009
Answer:
The answer is 0.009.
Step-by-step explanation:
The total number of people from which only 9 earned a perfect score = 1,000.
The number of people who earned a perfect score = 9
The decimal that represents the number of people who earned a perfect score = The number of people who earned a perfect score ÷ The total number of people concerned = 9 ÷ 1,000 = 0.009.

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.
Third-degree, with zeros of −4, −3, and 1, and a y-intercept of −11.
Given zeros -4, -3, and 1, and a y-intercept of -11, the corresponding third-degree polynomial function can be formulated as y = (11/12)(x + 4)(x + 3)(x - 1).
Explanation:To construct a third-degree polynomial function, we first need to define the polynomial based on its zeros. Given that the zeros are -4, -3, and 1, we can write the polynomial function in the form [y = a(x + 4)(x + 3)(x - 1)], where 'a' is the coefficient that affects the y-intercept. Because the y-intercept is -11, we set the value of y to -11 when x equals 0 to solve for 'a'. Thus the equation becomes [ -11 = a * 4 * 3 * -1], which simplifies to [a = -11/(-12) = 11/12]. Therefore, the polynomial function with the stated properties is [y = (11/12)(x + 4)(x + 3)(x - 1)] .

The third-degree polynomial with zeros at -4, -3, and 1 and a y-intercept of -11 can be written as P(x) = 0.917(x+4)(x+3)(x-1).
Explanation:To construct a third-degree polynomial with zeros at -4, -3, and 1, we write the factored form of a polynomial P(x), with the zeros plugged into the factors: P(x) = a(x+4)(x+3)(x-1). The term 'a' is a coefficient that we can find using the provided y-intercept of -11.
Because the y-intercept happens when x = 0, we substitute x = 0 and y = -11 into the polynomial: -11 =a(0+4)(0+3)(0-1). Solving for 'a' gives a = 11/12 or 0.917.
Thus, the resulting third-degree polynomial in lowest terms is P(x) = 0.917(x+4)(x+3)(x-1).

Hayk was walking around the cross-shaped pool with 10m-long sides , while Karlen was swimming in it. During the time Hayk got from point A to point B, Karlen swam diagonally from point B to A and back.
By what percent did the distance covered by Karlen exceed that of Hayk ? (round your answer to the nearest tenth)
Answer:
5,41%
Step-by-step explanation:
Remark
It's hard to interpret what % increase means. I'm going to work first with the actual increase and then I'll give the % increase. The answer I give will likely be in your choices, but it could still be incorrect.
Givens
Walking distance from A to B = 10 units down + 10 units east + 10 units down + 10 units east + 10 units down + 10 units east = 60 units.
Swimming distance = 2*sqrt(10^2 + 30^2) = 63.25 units.
Solution
The difference = 63.25 - 60 = 3.25
The % increase = (3.25/60)*100 = 5.41%

Two consecutive integers have a sum of 61 . Find the integers.
Answer:
The integers are, 30 and 31
Step-by-step explanation:
Given the statement: Two consecutive integers have a sum of 61 .
Let x and x+ 1 are the two consecutive integers.
then;
as per the given condition we have;
[tex]x +(x+1) = 61[/tex]
Combine like terms;
[tex]2x+1 = 61[/tex]
Subtract 1 from both sides ;
[tex]2x + 1-1 = 61 -1[/tex]
Simplify:
2x = 60
Divide both sides by 2 we get;
x = 30
and
value of x+1 = 30+1 = 31
Therefore, the integers are, 30 and 31.

What is the area of ACDE?
A.
24 square centimeters
B.
30 square centimeters
C.
60 square centimeters
Reset Next
Answer:
Option B is correct .i.e., 30 square centimeters
Step-by-step explanation:
We have to find area of ACDE.
From given figure ACDE is made up of two triangles ΔBCD & ΔABE
So, Area of ACDE = Area of ΔBCD + Area of ΔABE
Area of traingle = [tex]\frac{1}{2}\times Base\times Height[/tex]
⇒ Area of ACDE = [tex]\frac{1}{2}\times CD\times BF+\frac{1}{2}\times AB\times AE[/tex]
= [tex]\frac{1}{2}\times6\times2+\frac{1}{2}\times4\times12[/tex]
= [tex]6+2\times12[/tex]
= [tex]30\:cm^2[/tex]
Therefore, Option B is correct .i.e., 30 square centimeters
Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter. How long is the remaining piece of ribbon?
Answer:
[tex]\frac{7}{10}[/tex]
Step-by-step explanation:
Carrie has 2 meters of ribbon. She cuts off pieces of ribbon that are 5/10 meter, 1/10 meter, and 7/10 meter
Lets add all the cut of pieces and subtract it from 2 meters
[tex]\frac{5}{10} +\frac{1}{10}+\frac{7}{10}=\frac{13}{10}[/tex]
Now we subtract 13/10 from 2 meters
[tex]2 - \frac{13}{10}[/tex]
To subtract , make the denominator same
[tex]\frac{2*10}{1*10} - \frac{13}{10}=\frac{20}{10} - \frac{13}{10}=\frac{7}{10}[/tex]
7/10 meter is the remaining piece of ribbon
After adding the lengths of the ribbon pieces Carrie cut (1.3 meters), the remaining ribbon length is calculated by subtracting this from the original length, leaving Carrie with 0.7 meters of ribbon.
Explanation:Carrie starts with 2 meters of ribbon and cuts off pieces measuring 5/10 meter, 1/10 meter, and 7/10 meter. To find the length of the remaining ribbon, we need to add the lengths of the pieces she has cut and then subtract this total from the original length of the ribbon.
First, we add the lengths of the cut pieces: 5/10 meter + 1/10 meter + 7/10 meter = 13/10 meters or 1.3 meters.Next, we subtract this total from the original 2 meters: 2 meters - 1.3 meters = 0.7 meters.Therefore, the remaining piece of ribbon is 0.7 meters long.

What is 35.6 × 10−4 in standard form?
[tex]35.6\times10^{-4}=35.6\times0.0001=0.00356[/tex]
[tex]a^{-n}=\dfrac{1}{a^n}\\\\10^{-4}=\dfrac{1}{10^4}=\dfrac{1}{10000}=0.0001[/tex]
Final answer:
0.00356.
Explanation:
The question requires us to express the product of a decimal number and a power of ten in standard form. To find 35.6 times 10^-4 in standard form, we can use the rule of multiplying a decimal number by a power of ten. Multiplying by 10^-4 means we move the decimal point four places to the left.
So, 35.6 × 10^-4 becomes 0.00356. This is the number 35.6 shifted four decimal places to the left, as the exponent on the ten is negative, indicating division by ten for each unit of the exponent.

Answer: Correct answer is 1st option , 12.3
Step-by-step explanation:
We can find the value of x by calculating the tangent of the angle 39.
We know, that tangent of an angle in a triangle = Perpendicular/Base, corresponding to that angle.
So, tan 39 = 10/x
Again, we know that tan 39 = .81
So, .81 = 10/ x
or, x = 10/.81
or, x = 12.34
So value of x to the nearest tenth = 12.3
Hope thsi helps
Thank you
For the given central angle, determine the distance traveled along the unit circle from the point (1, 0).
180 degrees to units
How do i figure this out ?
Answer:
The length of a 180° arc of a unit circle is π ≈ 3.14 units.
Step-by-step explanation:
Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to
... (180°/360°) × circumference = (1/2)×circumference
For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.
Answer:
A central angle of 180 degrees corresponds to half of the unit circle, and the circumference of the unit circle is 2π units. So, the distance traveled along the unit circle from the point (1, 0) is half of the circumference, which is 1/2 * 2π = π units. Thus, the answer is 3.14 units (approximately).

Solve for r. -13= r/9 +8
Answer:
r = -189
Step-by-step explanation:
-13 - 8 = r/9
- 21 = r/9
r = 9 * -21
r = -189
Answer:
r = -189
Step-by-step explanation:
-13= r/9 +8
To solve this equation, we will start by subtracting 8 from each side

Elissa wants to set up a rectangular dog run in her backyard. She has 32 feet of fencing to work with and wants
to use it all. If the dog run is to be x feet long, express the area of the dog run as a function of x.
Perhaps jumping up the points will get answers.
A(x) = x(16 -x)
Step-by-step explanation:Area is the product of length and width. If the length is x, then the width will be half of the total perimeter less the two sides of length x, (32-2x)/2 = 16-x.
So, the area is ...
... A = length · width
... A(x) = x(16 -x)
_____
If you like, you can expand this to ...
... A(x) = -x² +16x
The area of a rectangular figure is calculated by multiplying the length and the width of the figure. So, the area as a function of x is: [tex]A(x) = x(16 - x)[/tex]
Given that:
[tex]P = 32[/tex] --- the perimeter of the fence
Represent
[tex]x \to[/tex] length
[tex]y \to[/tex] width
The perimeter of a rectangular fence is calculated as:
[tex]Perimeter = 2 \times (Length + Width)[/tex]
So, we have:
[tex]P= 2 \times (x+ y)[/tex]
[tex]32= 2 \times (x+ y)[/tex]
Divide both sides by 2
[tex]16= x+ y[/tex]
Make y the subject
[tex]y = 16 - x[/tex]
The area (A) of the fence is:
[tex]Area = Length \times Width[/tex]
So, we have:
[tex]A = x \times y[/tex]
Substitute [tex]y = 16 - x[/tex]
[tex]A = x \times (16 - x)[/tex]
[tex]A = x(16 - x)[/tex]
So, the area as a function of x is:
[tex]A(x) = x(16 - x)[/tex]
