Vertical angles are opposite each other when two lines intersect and are equal. Linear pairs of angles are adjacent angles that form a straight line and their sum is always 180 degrees. The difference lies both in their position and their angle sum.
Explanation:The main difference between vertical angles and linear pairs of angles derives from their positioning and sums. Vertical angles are angles opposite each other when two lines intersect. Vertical angles are always congruent, meaning they have the same measure.On the other hand, linear pairs of angles are adjacent angles whose non-common sides are opposite rays or in other words, they form a straight line. The sum of a linear pair of angles is always 180 degrees.
So, in sum, the difference lies in their positioning (vertical angles are opposite, linear pair angles are adjacent) and in their sum (vertical angles are equal, linear pair angles sum to 180 degrees).

Answer: (3, 0).What number can you cube that is bigger than 600 but smaller than 800
9 to the power of three, or cubed = 720 which is between 600 and 800.
The number you're looking for would be a decimal between approximately 8.375 and 8.6. When these numbers are cubed, they fall in the range of 600 to 800.
Explanation:The question at hand is asking about cubing a number to get a result that is larger than 600 but smaller than 800. We are looking to find the cube root of numbers in this range. The integer cube roots closest to this range are the cube root of 512 (which is 8) and the cube root of 729 (which is 9).
However, neither of these is a number that you could cube to end up in the 600 to 800 range. Therefore, the desired number is not a whole number, but a decimal. If you estimate, any number between 8.375 and 8.6, when cubed, should meet the condition—meaning it would be larger than 600 but still less than 800.

How long does it take Callie to complete one full swing?
A.
20 seconds
B.
5 seconds
C.
10 seconds
D.
60 seconds
She takes 20 seconds
Answer: A. 20 seconds
Step-by-step explanation:
We know that if a function has a repeating pattern then it is called a periodic function (like sine or cosine).
The period is the length of the smallest interval that contains exactly one copy of the repeating pattern. It is the horizontal distance required for the graph of a periodic function to complete one cycle.
From the graph it can be seen that, the horizontal distance required for the graph of a periodic function= 20 .
Therefore, it takes 20 seconds by Callie to complete one full swing.
Find the circumference of the circle if the square has an area of 144 m. Give your answer to the nearest tenth. Use 3.14 for pie
To find the circumference of the circle, we need to know its radius. However, in this question, we are given the area of a square instead. We can use the relationship between the circle and square to solve the problem.
Explanation:To find the circumference of a circle, we need to know its radius.
However, in this question, we are given the area of a square instead.
We can use the relationship between the circle and square to solve the problem.
First, let's find the side length of the square. The area of the square is given as 144 m².
We can find the side length by taking the square root of the area: √144 = 12 m.
Since the square and circle are related, the side length of the square is equal to the diameter of the circle.
Therefore, the radius (r) of the circle is half of the side length of the square, which is 6 m.
Now, we can find the circumference (C) of the circle using the formula C = 2πr.
Substituting the value of the radius, we get C = 2 × 3.14 × 6 ≈ 37.68 m.
Rounded to the nearest tenth, the circumference of the circle is approximately 37.7 m.
Final answer:
To calculate the circumference of the circle from the area of the square, we find the diameter of the circle (equal to the side length of the square) and divide it by two to get the radius. We then apply the formula C = 2πr using 3.14 for π to find the circumference, which is 37.7 m to the nearest tenth.
Explanation:
To find the circumference of the circle when the area of the square is 144 m², we need to understand the relationship between the square and the circle. First, let's determine the side length of the square. The area of the square (A) is given by the formula A = a², where a is the side length of the square. If the area is 144 m², we take the square root of 144 to find that a = 12 m. Now, since the circle fits perfectly inside the square, the diameter of the circle is equal to the side length of the square, which is 12 m. Hence, the radius (r) of the circle is half of that, so r = 6 m.
Now, we use the formula for the circumference of a circle, which is C = 2πr. Substituting the value of π with 3.14 and r with 6 m, we get C = 2 * 3.14 * 6. This results in a circumference of 37.68 m. To give the answer to the nearest tenth, we round it to 37.7 m. Therefore, the circumference of the circle is 37.7 m.

Math graph please help 35 points
In order to better find the points on this graph, we need to convert it from standard form to slope-intercept.
We can do that by solving for y.
-7y + 8 = 21x - 6
Subtract 8 from both sides.
-7y = 21x - 14
Divide both sides by -7
y = -3x + 2
Now that the equation is in slope-intercept, we can find two points on the line.
We know that (0, 2) will be the first point, because 2 is the y-intercept.
We can plug 1 into the x value of the equation to find the corresponding y value.
y = -3(1) + 2
y = -3 + 2
y = -1
The second point is (1, -1)
It's the linear function.
The slope-intercept form: y = mx + b.
-7y + 8 = 21x - 6 subtract 8 from both sides
-7y = 21x - 14 divide both sides by (-7)
y = -3x + 2
We need only two points:
for x = 0 → y = -3(0) + 2 = 0 + 2 = 2 → (0, 2)
for x = 2 → y = -3(2) + 2 = -6 + 2 = -4 → (2, -4)
Which equation represents y = x^2 − 8x + 5 in vertex form?
A) y = (x − 4)^2 − 9
B) y = (x − 4)^2 + 11
C) y = (x − 4)^2 + 21
D) y = (x − 4)^2 − 11
Answer: D
Step-by-step explanation:
y = x² - 8x + 5
-5 -5
y - 5 = x² - 8x complete the square by adding [tex](\frac{-8}{2})^{2}[/tex] to both sides
y - 5 + 16 = x² - 8x + 16 the right side is a perfect square: (x - 4)²
y + 11 = (x - 4)²
-11 -11
y = (x - 4)² - 11

The volume of the cone can be calculated using fofmula
[tex]V=\dfrac{1}{3}\cdot b\cdot h,[/tex] wher b is the area of the base and h is the hieght.
Multiply the whole equation by 3:
[tex]3V=b\cdot h.[/tex]
Divide this equation by b:
[tex]h=\dfrac{3V}{b}.[/tex]
Answer: [tex]h=\dfrac{3V}{b}.[/tex]
We rearranged the equation v=1/3bh to solve for h, the height of the cone, by first multiplying by 3 to cancel the 1/3 and then dividing by b, resulting in h=3v/b.
The question is asking to Solving for Variable for h in the formula v=1/3bh, where v is the volume of a cone, b is the base area, and h is the height.
To find h, we need to rearrange the equation by first multiplying both sides by 3 to cancel out the 1/3 in front of bh.
So, it becomes 3v=bh.
Then, we divide both sides by b to isolate h, which gives us h=3v/b.
So the height of the cone is h=3v/b.

The numerical coefficient of the [tex]a^8*b^2[/tex] term in the expansion of [tex]((1/3)a^2 - 3b)^6[/tex] is -45/16.
Explanation:The numerical coefficient of the [tex]a^8*b^2[/tex] term in the expansion of [tex]((1/3)a^2 - 3b)^6[/tex] can be found using the binomial theorem, which states that [tex](x+y)^n = \sum (n choose k) x^(^n^-^k^) y^k[/tex] where the sum is from k=0 to n. Here, x = [tex](1/3)a^2[/tex], y = -3b, and n = 6.
In the term [tex]a^8*b^2, a^2[/tex] is raised to the 4th power and -3b is raised to the 2nd power. Hence, we are looking for the coefficient in the term in the binomial expansion where [tex](1/3)a^2[/tex] is raised to the 4th power and -3b is raised to the 2nd power.
This can be calculated by multiplying together the coefficient '6 choose 4', the 4th power of [tex](1/3)a^2[/tex], and the 2nd power of -3b.
That leads to coefficient =[tex](6 choose 4)*((1/3)^4)*(-3)^2 * a^8 * b^2[/tex]. After calculation this simplifies to -45/16.

10p+10q factors to 10(p+q). If we apply the distributive property, we can distribute the 10 to each term inside (p and q) to get
10(p+q) = (10 times p)+(10 times q) = 10*p + 10*q = 10p+10q
so we get the original expression again. Here 10 is the GCF of the two terms.
--------------------------------------------------------------
Plug p = 1 and q = 2 into the factored form
10*(p+q) = 10*(1+2) = 10*(3) = 30
As a check, let's plug those p,q values into the original expression
10*p+10*q = 10*1+10*2 = 10+20 = 30

The vertices of triangle rst are r(–1,–2), s(2,–1), and t(4,2). If δjkl ∼ δrst and the length of kl is units , what is the length of jk?
Answer:
3.16 units
Step-by-step explanation:
It has been given that the triangles JKL and the triangle RST are congruent.
That implies that, the length of the side JK, KL, and JL is equivalent to the length of the sides RS, ST, and RT respectively.
Now, to find the length of JK we need to find the length of the side RS. The coordinates of the points R and S are [tex](-1,-2)[/tex] and [tex](2,-1)[/tex].
The length of the side RS is equal to the distance between point R and S.
RS [tex]=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]= \sqrt{(2-(-1))^2+(-1-(-(-2))^2}[/tex]

A satellite camera takes a rectangular-shaped picture. The smallest region that can be photographed is a 4-km by 8-km rectangle. As the camera zooms out, the length l and width w of the . rectangle increase at a rate of 3 km/sec. How long does it take for the area A to be at least 5 times its original size?
To find the time it takes for the area to be at least 5 times its original size, we need to solve an equation involving the rates of increase for the length and width of the rectangle. The original area is 32 km² and the rates of increase are both 3 km/sec. By substituting these values into the equation and solving for time, we can determine the answer.
Explanation:To determine how long it takes for the area A to be at least 5 times its original size, we first need to find the original area and then solve for the time it takes for the area to reach 5 times that value.
The original area is equal to the length multiplied by the width, so it is A = 4 km * 8 km = 32 km².
Let's denote the rate at which the length and width increase as dl/dt and dw/dt respectively. We know that dl/dt = dw/dt = 3 km/sec.
To find the time it takes for the area to be 5 times its original size, we need to solve the equation 32 + 3l(t) * 3w(t) = 5 * 32, where l(t) and w(t) are the length and width at time t.
Simplifying the equation, we get 9lw - 160 = 0.
Since we're given the rates at which l and w increase, we can substitute l and w with their formulas: l(t) = 4 + 3t and w(t) = 8 + 3t.
Substituting these formulas into the equation, we get 9(4 + 3t)(8 + 3t) - 160 = 0.
Solving this equation will give us the value of t, which represents the time it takes for the area to be at least 5 times its original size.
