Which linear relationship can be described as a function with direct variation?
Answer:
The line passing through the origan (Graph 2 on Edu is correct.)
Step-by-step explanation:
The linear function described as a function with direct variation is the second graph .
What is Linear Relation?Only those linear relationships where b = 0 relate to direct variation because the formula for a linear relationship between two variables is y = m x + b. A straight line that travels through the origin is the graph of direct variation (of a proportional relationship).
Given :
The four graphs of a line. Each graph represents a linear equation .
As, Direct variation equation does not have y intercept 'b'
and, Direct variation function crosses through origin .
First graph does not crosses through origin.
Second graph crosses through origin (0,0)
Also, Graphs with vertical and horizontal lines do not directly depict change.
Hence, second graph is the linear function.

This figure consists of two semicircles and a rectangle.
What is the perimeter of this figure?
Use 3.14 for π.
The perimeter of the figure is 423.52 m
What is Area of Rectangle?The area of Rectangle is length times of width.
From the figure the length of rectangle is 105m and width is 68m.
Perimeter of rectangle=2(length+width)
First the rectangle part with the length is 105m,
2(105)=210m
For the semicircle part, the circumference of the circle is 2πr
The circumference of the semicircle is 1/2(2πr)=πr
Diameter of semicircle=68
Radius is 34
circumference of the semicircle is 34(3.14)=106.76
As there are two semicircles=2(106.76)=213.52
The total perimeter of this figure is 213.52+210=423.52m
Hence, the perimeter of this figure is 423.52 m

A bag contains 20 marbles: 12 red, 4 blue, 3 yellow, and 1 green. Arielle takes out 2 marbles. What is the probability that they are both blue?
Total number of marbles in the bag =20
Number of blue marbles =4
Now we just want two blue marbles out of four.
Probability of taking out first marble which is blue =4/20
Now after we took out one blue marble , number of blue marbles left are 3.
Probability of taking out second marble which is blue =3/20
Total probability = 4/20 *3/20 = 12/400
So probability of taking out two blue marbles is 0.03 or 12/400.

What is a function?A relation is a function if it has only One y-value for each x-value.
The given ordered pairs are {(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)}
minus nine comma one,
minus five comma two
zero comma seven
one comma three
six comma minus ten
If Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function.
Then we can replace with (-9, -6) (-5,1 ) (1,12) to make it incorrect. Two x values should not have same value.
Hence (-9, -6) (-5,1 ) (1,12) ordered pairs that could be used to show that this claim is incorrect.

a varies directly as b and inversely as the square of c. If a = 197 when b = 5 and c = 5, find a if b = 3 and c = 3
Final answer:
The value of 'a' is found to be approximately 328.33 when b = 3 and c = 3, using the constant of proportionality obtained from the given values a = 197 when b = 5 and c = 5.
Explanation:
When a quantity varies directly as another quantity and inversely as the square of a third quantity, we can express this relationship with the following equation:
a = k x (b / c2)
where k is the constant of proportionality. Given that a = 197 when b = 5 and c = 5, we can solve for k:
197 = k x (5 / 52)
197 = k x (5 / 25)
197 = k / 5
k = 197 x 5
k = 985
Now we can use this value for k to find a when b = 3 and c = 3:
a = 985 x (3 / 32)
a = 985 x (3 / 9)
a = 985 x (1/3)
a = 328.333...
Hence, the value of a, when b = 3 and c = 3, is approximately 328.33.

2≤x≤9.
The average rate of change of the function h(x) = x² - 7x +7 over the interval 2 ≤ x ≤ 9 is 4.
Explanation:The average rate of change for a function is determined by the difference in y values divided by the difference in x values over a specified interval. In this case, the function is h(x) = x² - 7x + 7, and the interval is 2 ≤ x ≤ 9. First, we calculate h(2) and h(9) for the y values.
h(2) = (2)² - 7(2) + 7 = 4 - 14 + 7 = -3
h(9) = (9)² - 7(9) + 7 = 81 - 63 + 7 = 25
Then, apply the formula for average rate of change which is (h(9) - h(2)) / (9 - 2).
(25 - (-3)) / (9 - 2) = 28 / 7 = 4

A company sells cereal in two different -sized boxes.The smaller box has the dimensions of 12-inch,2-inch and 7 3/4 i.The height of the smaller box is 80% of the height of the lager box,while the other two dimensions are the same for both boxes.What is the difference in the volumes of the two boxes?
Answer: The answer is 232.5
Step-by-step explanation:First you to set up the proportion. If 80% equals to 12. You Would do 80 over hundred becuase percent is out of hundred (80/100) then you would do 12 over x or any other variable. FROM there on you would to the butter fly method. Cross multiply . ( 80 times variable, 12 times 100) now to isolate the variable you have to do inverse operation. So now do 1200 divided by 80 . And 80 divided by 80. Now you know.
X=15.
But were no done yet lol. Now do length times width times height to get the volume. 15 times 2 times 31/4 (7 3/4) . now we're done. Your welcome
Which equation can be used to solve for x in the following diagram?
The equation that represents the value of [x] is -
x + 4x - 85 = 90.
What is right angle? What is equation modelling? What is a mathematical equation and expression?In geometry and trigonometry, a right angle is an angle of exactly 90 degrees or π/2 radians corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is a geometrical image as shown.
We can write the equation as -

Answer:
The correct answers are -
Definition, Postulate, Corollary and Theorem.
Step-by-step explanation:
When we want to prove something, we already know that one thing is already there, proven and we have to prove the other part.
A definition is something that is absolutely true and valid. It can also be used to prove another statement.
A postulate is a statement that is assumed to be true, and is used to prove other statements.
A corollary is a direct consequence of an already proven fact, and can also be used used to prove other statements.
Theorems are already proven statements. These are used to prove other statements as well.

Now, he's probably living his best life right now and doesn't even know what I'm typing right now, either that, or he's working at McDonald's. Honestly though, time flies by so fast though, it really is crazy.
