Given the following statement:
In any circle, it takes ------ diameters to equal the circumference
As we know, the circumference = 2πr = π d
So, the answer will be π which is ≈ 3.142
The decimal part = 0.142 ≈ 1/7
So, the answer will be option B. about 3 1/7

5 Which of the following functions are an example of continuous growth?
In order to have a function that represents continuous growth, the base value that has a variable as exponent must be the constant value "e":
[tex]\begin{gathered} f(x)=a\cdot b^{cx}\\ \\ b=e \end{gathered}[/tex]Looking at the options, the functions that have this base value are options I and II.
Therefore the correct option is A.
Without doing any calculations, compare expression A to expression B.5A.x 2506B. (250) + ({ x 250)ХChoose the words to complete the comparison.Expression A is Choose...v expression B.r
We have two expressions and we have to compare them.
We don't need to calculate the exact value of each expression. We can left them as products of 250.
Then, expression A is already 5/6 of 250.
We can rearrange expression B as:
[tex]\begin{gathered} B=(\frac{1}{3}\cdot250)+(\frac{1}{2}\cdot250) \\ B=(\frac{1}{3}+\frac{1}{2})\cdot250 \\ B=\frac{2+3}{3\cdot2}\cdot250 \\ B=\frac{5}{6}\cdot250 \end{gathered}[/tex]Expression B is also 5/6 of 250, so the two expressions are equal.
Answer: expression A is equal to expression B.

A bicyclist rides 11.2 kilometerseast and then 5.3 kilometers southWhat is the angle of thebicyclist's resultant vector?
Given
A = 11.2 km East
B = 5.3 km south
Find
Angle of the resultant vector
Explanation
Angle of the resultant vector is given by
[tex]tan\emptyset=\frac{Bsin\alpha}{A+Bcos\alpha}[/tex]Here angle between both the vectors is 90 degree
[tex]\begin{gathered} tan\emptyset=\frac{Bsin\alpha}{A+Bcos\alpha}=\frac{11.2(sin90)}{5.3+11.2(cos90)} \\ tan\emptyset=\frac{11.2}{5.3} \\ tan\emptyset=2.11320755 \\ \emptyset=64.67degrees \end{gathered}[/tex]So Angle made from origin = 270+64.67
= 334.67 degree = 334.7 degree(approx)
Final Answer
Angle of resultant Vector = 334.7 degree

We are given a right-angled triangle.
The given angle is 50°40'
Let us convert the minute part to degrees
[tex]\begin{gathered} \frac{40^{\prime}}{60}=0.67\degree \\ 50\degree+0.67\degree=50.67\degree \end{gathered}[/tex]With respect to the angle 50.67°, the adjacent side is 17.2' and the opposite side is b.
Recall from the trignonometric ratios,
[tex]\tan \theta=\frac{opposite}{adjacent}[/tex]For the given case, we have
θ = 50.67°
Adjacent = 17.2'
Opposite side = b
Let us substitute these values into the above formula to find the value of b.
[tex]\begin{gathered} \tan (50.67\degree)=\frac{b}{17.2} \\ b=\tan (50.67\degree)\cdot17.2 \\ b=1.2205\cdot17.2 \\ b=21.0^{\prime} \end{gathered}[/tex]Therefore, the value of b is 21.0'
find the area and the circumference of a circle with a diameter of 6 yards use the value 3.14 for it and do not round your answer be sure to include the correct unit in your answer
Given a circle with a diameter of 6 yards
The radius of the circle (r) = half of the diameter (d)
so,
[tex]r=0.5\cdot d=0.5\cdot6=3\text{ yards}[/tex]The area of the circle is given by the formula:
[tex]\text{Area}=\pi\cdot r^2[/tex]Use: pi = 3.14
so,
[tex]\text{Area}=3.14\cdot3^2=3.14\cdot9=28.26\text{ square yards}[/tex]The circumference is given using the formula:
[tex]C=2\cdot\pi\cdot r[/tex]So, the circumference is:

The formula for the slope of a line is given by:
m = (y2- y1)/(x2 - x1)
where (x1,y1) and (x2,y2) are two points in the line.
1) When a line has a slope with value 0, this means the line is horizontal. In this case all values of y are the same for any value of x.
Thus, an example of two point in a line with slope 0 can be:
(2,6) and (7,6)
These points are the save value of y, if you replace thes values into the formula for m the result is zero because you have zero in the denominator of the right side of the equation.
2) When a line has an undefined slope, this means that the line is vertical. In this case all values of x are the same for any value of y.
Thus, an example of two points in a line with undefinied slope can be:
(2,-4) and (2,6)
If you replace the previoues values into the formula for m, you get 0 in the denominator of the right side of the equation, that is, you have a division by zero, which means that there is an indetermination there.
1-) drawing the following triangle in the cartesian plane The vertices of the triangle are the points A (3,2); B (2,0); and C (-1,-4).2-) use the distance fórmula to find the length of the following line segments or side of your triangle above AB= distance 1 =called. d¹?=CA distance 2 = called d²? BC = distance 3 = called d³?
We have to draw the triangle with vertices:
[tex]\begin{gathered} A(3,2) \\ B(2,0) \\ C(-1,-4) \end{gathered}[/tex]For doing so, we will draw the points A, B, and C on the plane, and we will trace segments from A to B, from B to C, and from C to A.
We remember that for locating a point in the plane, we call the first number the x-coordinate and the second number the y-coordinate. We locate the x-coordinate on the x-axis and the y-coordinate on the y-axis, and the intersection will be the point desired.
Having this in mind, we obtain:
And joining the segments, the triangle obtained is:
Consider the expressions 3x(x - 2) + 2 and 2x2 + 3x – 16.
For x = 3, each expression has a value of 11. For x = 6, each expression has a value of 74. These results suggest that the expressions are equivalent
Explanation:The given expressions are:
3x(x - 2) + 2 and 2x² + 3x - 16
Substitute x = 3 into 3x(x - 2) + 2
3(3)(3 - 2) + 2
= 9(1) + 2
= 9 + 2
= 11
Substitute x = 3 into 2x² + 3x - 16
2(3)² + 3(3) - 16
2(9) + 9 - 16
18 + 9 - 16
= 11
Substitute x = 6 into 3x(x - 2) + 2
3(6)(6 - 2) + 2
18(4) + 2= 74
Substitute x = 6 into 2x² + 3x - 16
2(6)² + 3(6) - 16
2(36) + 18 - 16
72 + 2
= 74
For x = 3, each expression has a value of 11. For x = 6, each expression has a value of 74. These results suggest that the expressions are equivalent
The revenue function R in terms of the number of units sold, a, is given as R= 380x - 0.1x^2where R is the total revenue in dollars. Find the number of units sold a that produces a maximum revenue?Your answer is x= What is the maximum revenue? __
The maximum revenue corresponds to the y-coordinate of the vertex of the graph of the revenue function. And the number of units sold that produces a maximum revenue corresponds to the x-coordinate of the vertex of the graph of the revenue function.
Then, we can find the vertex of the revenue function. For this, we can rewrite the function in its vertex form by completing the square.
[tex]\begin{gathered} f(x)=ax^{^2}+bx+c\Rightarrow\text{ General form} \\ f(x)=a(x-h)^2+k\Rightarrow\text{ Vertex form} \\ \text{ Where }(h,k)\text{ is the vertex} \end{gathered}[/tex]Then, we have:
Step 1: Reorder the terms.
[tex]\begin{gathered} R=380x-0.1x^2 \\ R=-0.1x^2+380x \end{gathered}[/tex]Step 2: We use the general form to find the values of a,b and c.
[tex]\begin{gathered} a=-0.1 \\ b=380 \\ c=0 \end{gathered}[/tex]Step 3: We find the value of h using the below formula.
[tex]h=\frac{-b}{2a}[/tex][tex]\begin{gathered} h=\frac{-380}{2(-0.1)} \\ h=\frac{-380}{-0.2} \\ h=1900 \end{gathered}[/tex]Step 4: We find the value of k using the below formula.
[tex]k=c-\frac{b^2}{4a}[/tex][tex]\begin{gathered} k=0-\frac{380^2}{4(-0.1)} \\ k=\frac{-144400}{-0.4} \\ k=361000 \end{gathered}[/tex]Step 5: We substitute the values of a, h and k into the vertex form.
[tex]\begin{gathered} \begin{equation*} f(x)=a(x-h)^2+k \end{equation*} \\ R=-0.1(x-1900)^2+361000 \end{gathered}[/tex]Thus, the vertex of the revenue function is the ordered pair (1900,361000).
AnswerThe number of units sold that produces a maximum revenue is 1900, and the maximum revenue is $361000.

Hi I need help to find the value of Q
Given the system of equations:
x - 3y = 4
2x - 6y = Q
Let's find the value of Q.
Let's solve the equations simulateneously using substitution method.
Rewrite the first equation for x:
• Add 3y to both sides of equation 1
x - 3y + 3y = 4 + 3y
x = 4 + 3y
• Substitute (4 + 3y) for x in equation 2:
2x - 6y = Q
2(4 + 3y) - 6y = Q
• Apply distributive property:
2(4) + 2(3y) - 6y = Q
8 + 6y - 6y = Q
8 + 0 = Q
8 = Q
Q = 8
Therefore, the value of Q is 8
ANSWER:

In this case, we'll have to carry out several steps to find the solution.
Step 01:
total students = 120

% = ?
Step 02:
% = part / whole * 100
% = 48 / 120 * 100
% = 40%
The answer is:
