Answer:
D. 8 cm
Step-by-step explanation:
Given :
Let the length of the arc be = l
radius of the arc, r = 2 cm
degree of angle subtended at the center by the arc, θ = 4 radian
Now we know that the angle subtended by an arc at the center of the circle whose radius is 2 cm will be,
θ = l/r
Therefore, we can write,
l = θ x r
l = 4 x 2
= 8 cm
So the length of the arc is 8 cm.

Gold mines in northern Nevada produce an average of 3.2 grams of gold per short ton (2,000 pounds) of ore. The value of gold is usually reported in troy ounces (ozt), and a troy ounce is equal to 31.1 grams (g). On average, how many troy ounces of gold are extracted from one short ton of Nevada ore
Answer:
0.1028938
Step-by-step explanation:
Given the following :
Average gold production in Northern Nevada =3.2 grams per short ton (2000 pounds)
Value of gold is measured in Troy ounces (ozt)
1 Troy ounces = 31.1 grams(g)
Number of Troy ounces of gold extracted from one short ton of Nevada ore ; let the number be t:
1 ozt = 31.1 g
t = 3.2 g
Cross multiply :
31.1 × t = 3.2 × 1
31.1t = 3.2
t = 3.2 / 31.1
t = 0.1028938 ozt
Hence, On average, 0.1028938 ozt of gold is extracted from one short ton of Nevada ore
The table shows the dimensions and the numbers of blades of grass on four rectangular pieces of sod. Select and drag the pieces of sod in order from greatest to least grass density, with greatest at the top and least at the bottom.
===============================================
Explanation:
Rectangle A has area 4*3 = 12 square feet. Divide the number of blades of grass over this area to get a density of 34188/12 = 2849. So the density for rectangle A is 2849 blades per square foot. Put another way, one square foot of rectangle A contains about 2849 blades of grass.Rectangle B has area 5*4 = 20 square feet and density 56340/20 = 2817 blades per square foot.Rectangle C has area 6*3 = 18 square feet and density 52632/18 = 2924 blades per square foot.Rectangle D has area 4*2 = 8 square feet and density 25248/8 = 3156 blades per square foot.The density order from greatest to least is therefore: D, C, A, B

BRAINLIEST TO THE FIRST PERSON TO ANSWER!!Maria solved an equation as shown below.
3 (x + 6) = 5 (x minus 4). 3 x + 18 = 5 x minus 20. 38 = 2 x. 19 = x.
What is the solution to Maria’s equation?
19
38
no solution
infinitely many solutions
Answer:
19
Step-by-step explanation:
3(x + 6) = 5(x - 4)
Distribute on both sides.
3x + 18 = 5x - 20
Subtract 3x from both sides. Add 20 to both sides.
38 = 2x
Divide both sides by 2.
19 = x
Maria followed the steps shown above and solved the equation correctly.
The solution is x = 19.
Answer: x = 19

Step-by-step explanation:
Answer:
Since we get '2' as an output when we input '0'
So, the function must be increasing the value of x by 2
We see that happen in the second case as well, as our input is incremented by 2
Hence, we can say that
f(x) = x + 2

Consider the function f(x) = round(x), which rounds the input, x, to the nearest integer. Is this function one-to-one? Explain or justify your answer.
Answer: The function is not one-to-one
Step-by-step explanation:
An one-to-one function is such that no two elements in the domain correspond to the same element in the range.
Now, we have the function:
y = f(x) = round(x)
Which rounds x to the nearest whole number.
Now, to round to the next whole number we must look at the first number after the decimal point.
If that number is 5 or larger, we round up
If that number is smaller than 5, we round down.
Then, for example:
f(1.2) = 1
because the first number after the decimal point is smaller than 5.
and:
f(1.1) = 1
f(1.2) = 1
f(1.2423) = 1
f(1.348) = 1
So we have a lot (if x is real, we have infinite) values of x that are maped into the same value in the range.
Then this can not be an one-to-one function.
Kareem says that the ratio 4 : 1 is equivalent to the ratio 12 : 9 because 4 1 8 5 12 and 1 1 8 5 9. Is Kareem correct? Explain how you know.
[tex]\bf Step-by-step~explanation:[/tex]
Kareem's statement: 4:1 is equal to 12:9. Let's see if this is correct.
[tex]\bf Step ~1:[/tex]
We have to simplify the ratios. Since 4:1 is already simplified, we do not have to do anything with it. 12:9 could be simplified. To do so, we need to find the greatest common factor (GCF) of both numbers. The GCF of 12 and 9 is 3. Since 3 is the GCF for both numbers, we divide them by 3.
[tex]\bf 12 /3=4\\9/3=3[/tex]
First number: 4
Second number: 3
Ratio: 4:3
[tex]\bf Step~2:[/tex]
We compare the ratio 4:3 to 4:1. Since they have different values, they are not equivalent to each other.
[tex]\large\boxed{\bf Our~final~answer: ~Kareem~is~wrong.}[/tex]
[tex]\bf {Explanation~in~Step~1}[/tex]
4 : 1 and 12 : 9 are not equivalent
Kareem is wrong
Correct question:
Kareem says that the ratio 4:1 is equivalent to the ratio 12:9 because
4 + 8 = 12 and 1 + 8 = 9. Is Kareem correct? Explain how you know
4 : 1 is in its simplest form already
12 : 9
= 12/9
= 4/3
= 4 : 3
Therefore,
4 : 1 and 12 : 9 are not equivalent
Kareem is wrong based on his assumption that 4 + 8 = 12 and 1 + 8 = 9

c
V - 18 < 30
Od
v + 18 > 30
Question 4 25 points)
Answer:
A. V + 18 < 30
Step-by-step explanation:
First of all, less than is the sign that points to the left,
Secondly, I'm guessing that y is actually V,
Before Ray gave Jan cards, she had 18,
so it is 18 plus V (the number of cards Ray gave her),
SO,
V + 18 < 30

Answer:
a = - 1.1
Step-by-step explanation:
The condition for a single variable function f(x) to be decreasing is f'(x) < 0.
f(x) = 4/x^2 - 6x + 9
Then, differentiating with respect to x on both sides we get,
f(x) = 4(-2)(1/x^3) - 6 < 0
-8/x^3 - 6 < 0
8/x^3 + 6 > 0
{Dividing both sides with - 1 and hence the inequality sign changes}
8/x^3 > -6
8 > - 6x³ {Multiplying both sides with x³}
6x³ > - 8 {Interchanging the sides}
x^3 > -8/6
⇒ x > - 1.1
So, a = - 1.1
Answer:
a = 3
Step-by-step explanation:
The function can be written as ...
f(x) = 4/(x -3)^2
This has a vertical asymptote at x=3 and will be decreasing for all values of x to the right of that -- on the interval (3, ∞).
a = 3

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The average rate of change in TQ) for the interval d = 4 and d = 10 is 0. Which statement must be true?
O The same number of tickets was sold on the fourth day and tenth day.
O No tickets were sold on the fourth day and tenth day.
O Fewer tickets were sold on the fourth day than on the tenth day.
More tickets were sold on the fourth day than on the tenth day.
Answer: The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given: [tex]T(d)[/tex] is a function that relates the number of tickets sold for a movie to the number of days 'd' since the movie was released.
Also, the average rate of change in T(d) for the interval d = 4 and d = 10 is 0.
Since the average rate determines the rate of change in the dependent variable (T(d)) with respect to the independent variable (d).
It means that there is no change from 4th day to 10th day in the number tickets sold.
Hence, the correct option is "The same number of tickets was sold on the fourth day and tenth day."
