Answer:
x = -0.907, 2.57
Step-by-step explanation:
Quadratic Formula: [tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]
Since we are given a = 3, b = -5, and c = -7 from our quadratic, we simply use the Quadratic Formula:
Step 1: Plug in variables
[tex]x=\frac{-(-5)+/-\sqrt{(-5)^2-4(3)(-7)} }{2(3)}[/tex]
Step 2: Solve
[tex]x=\frac{5+/-\sqrt{25+ 84} }{6}[/tex]
[tex]x=\frac{5+/-\sqrt{109} }{6}[/tex]
Step 3: Evaluate for decimals
You should get x = -0.906718 and 2.57338 as your answers.
Answer:
x = 2.57338441, − 0.90671775
Step-by-step explanation:
x = 5 ±√109/2 x 3
Times 2 by 3
x = 5 ± √109/6
x = 5 ± √109/6
x = 5 + √109/6
x = 5 ± √109/6
x = 5 - √109/6
x = 5 + √109/6, 5 - √109/6
x = 2.57338441, − 0.90671775
Based on your work in Question 1 through 3, what is the relationship between the radius, AB , and the tangent line, BC ? What can you conclude about any tangent line to a circle and the radius of the circle? Explain.
Answers
Without further context I can't say much other than the radius is perpendicular to the tangent. In other words, the radius and tangent line form a 90 degree angle. This is one particular radius and its not just any radius. The radius in question must have the point of tangency as its endpoint.
The radius, AB is perpendicular to the tangent line, BC so their slopes are negative reciprocals of one another. Because I generated a circle at random for this activity, this conclusion likely applies to any tangent line to a circle. In other words, the tangent line to any circle is perpendicular to the radius at their point of intersection.

For each of the following statements about sets A, B, and C, either prove the statement is true or give a counterexample to show that it is false.

b. If A∈BA∈B and B⊆CB⊆C, then A⊆CA⊆C.
c. If A∈BA∈B and B⊆CB⊆C, then A∈CA∈C.
d. If A∈BA∈B and B∈CB∈C, then A∈CA∈C.
Answers
Answer:
a. True
b. False
c. True
d. False
Step-by-step explanation:
a. Meaning
as we can see that x is an element of Y
So notation is
[tex]x \in Y[/tex]
Therefore x is the subset of Y if each of an element of X is also an element of Y.
So notation is
[tex]X \subseteq Y[/tex]
2. (a) We need to proof
When [tex]A \subseteq B and B \subseteq C \so A \subseteq C[/tex]
We will say that A, B and C are the set that is [tex]A\subseteq B\ and\ B\subseteq C[/tex]
When A = ∅ then [tex]A\subseteq C[/tex] which shows true, as the set of empty is a subset of each set.
Hence, it is safe to say that A is not the empty set.
Now we will proof directly
Let us say x be an element of A
[tex]x \in A[/tex]
As [tex]A \subseteq B,[/tex] each of the element of A is also an element of B
[tex]x \in B[/tex]
As [tex]B \subseteq C[/tex], each if the element of B is also an element of C
[tex]x \in C[/tex]
Therefore, as we can see that each of an element of A is also known an element of C, that states [tex]A \subseteq C[/tex]
So, the given statement is true, as we conclude with a proof.
(b). We will assume {1}, B = {{1},2} and C = {{1},2,3}
As in the point a, which is an element of B, that is [tex]A \in B[/tex] which is true
As all of the elements in B are also an element in C, [tex]B \subseteq C[/tex] which is also correct.
Although, [tex]A \subseteq C[/tex] is false as 1 is an element of A that is not in C.
(c) We need to proof
When [tex]A \in B\ and \ B \subseteq C[/tex] then [tex]A \in C[/tex]
Let us assume that A, B and C are the sets that [tex]A\in B\ and\ B \subseteq C[/tex]
As, [tex]A \in B, \which\ is\ an\ element\ of\ the\ set\ B[/tex]
[tex]A\in B[/tex]
As, [tex]B \subseteq C[/tex], each of the element of B is also an element of C
[tex]A\in C[/tex]
So, its true.
(d) We will assume {1}, B = {{1},2} and C = {{1},2,3}
As in the point a, which is an element of B, that is [tex]A \in B[/tex] which is true
As {{1},2} is an element of B, [tex]B \in C[/tex] is correct
Although [tex]A \in C[/tex] is not correct as {1) is not an element in C.
SO the statement is false

Can you tell me the answer to (−7c+8d)0.6
Answers
Answer:
-4.2c+4.8d
Step-by-step explanation:
(−7c+8d)0.6
Distribute
-7c*.6 + 8d * .6
-4.2c+4.8d
Answer:
-4.2c + 4.8d
Step-by-step explanation:
We would like to distribute the 0.6 in the expression (-7c + 8d) * 0.6.
Remember that when distributing, we multiply the "outside number" (0.6 in this case) by each of the "inside numbers" (-7c and 8d) and then add those products.
So, the first product will be: 0.6 * (-7c) = -4.2c. The second product will be: 0.6 * 8d = 4.8d. Add these together: -4.2c + 4.8d.
The answer is thus -4.2c + 4.8d.

breadth=10
(sorryy im not really sure but i hope it helps :D)
Answer:
Length = 25 cm
Breadth = 10 cm
Step-by-step explanation:
Let breadth of the room be 'x'
Let length of the room be ''
Perimeter ( P ) = 70 cm
Now, let's find the breadth of the room 'x '
Perimeter of rectangle = 2(l+b)
plug the values
70=2(2.5x+x)
Collect the like terms
70=2x3.5x
Calculate the product
70=7x
Swap the sides of the equation
7x=70
Divide both sides of the equation by 7
7x / 7= 70/7
Calculate
x=10cm
Breadth = 10 cm
Now, Let's find the length of the room ' 2.5x '
Length of the room = 2.5x
Plug the value of X
2.5x10
Calculate the product
25cm
Thus , The length and breadth of the room is 25 cm and 10 cm respectively.

Answer:
469.4ft²
Step-by-step explanation:
We have ∆ WXY in the above question,
From which we have obtained the following values
Angle W = 27°
Angle X = ?
Angle Y = 40°
Side w =?
Side x = ?
Side y = 38ft
Area of the triangle= ?
Step 1
We find Angle X
We know that the Sum of angles in a triangle = 180°
In the question above, we are given 2 angles
Hence,
Angle X = 180 - ( Angle W + Angle Y)
= 180° - (27 + 40)°
= 180° - 67°
Angle X = 113°
Step 2
Find the sides w and x
We find these sides using the Rule of sines
Rule of Sines =
a/ sin A = b/ Sin B = c/Sin C
Hence for triangle WXY
w/ sin W = x/ sin X = y/ sin Y
We have the following values
Angle W = 27°
Angle X = 113°
Angle Y = 40°
We are given side y = 38ft
Determining side w
w/ sin W= y/ sin Y
w/sin 27 = 38/sin 40
Cross Multiply
sin 27 × 38 = w × sin 40
w = sin 27 × 38/sin 40
w = 26.83879ft
w = 26.84ft
Determining side x
w/ sin W = x/ sin X
26.84/ sin 27 = x/sin 113
Cross Multiply
sin 113 × 26.84 = x × sin 27
x = sin 113 × 26.84/sin 27
x = 54.42041ft
x = 54.42ft
To find the area of triangle WXY
We apply the use of heron formula
= √s(s - w) (s - x) (s - y)
Where S = w + x + y/ 2
s = (38 + 26.84 + 54.42)/2
s = 59.63
Area of the triangle = √59.63× (59.63 - 38) × (59.63 - 26.84 ) × (59.63 - 54.42)
Area of the triangle = √ 220343.61423
Area of the triangle = 469.40772706541ft²
Hence, Approximately to the nearest tenth =469.4yd²
Question 14. A carousel makes one complete revolution every 75 seconds. Levi sits on the carousel 4 feet from its center. If the length of a carousel ride is 5 minutes, how many feet did Levi travel? E. 4 F. 16 G. 8π H. 32π
Answers
Answer:
The correct option is;
H. 32·π
Step-by-step explanation:
The given information are;
The time duration for one complete revolution = 75 seconds
The distance from the center of the carousel where Levi sits = 4 feet
The time length of a carousel ride = 5 minutes
Therefore, the number of complete revolutions, n, in a carousel ride of 5 minutes is given by n = (The time length of a carousel ride)/(The time duration for one complete revolution)
n = (5 minutes)/(75 seconds) = (5×60 seconds/minute)/(75 seconds)
n = (300 s)/(75 s) = 4
The number of complete revolutions - 4
The distance of 4 complete turns from where Levi seats = 4 ×circumference of circle of Levi's motion
∴ The distance of 4 complete turns from where Levi seats = 4 × 2 × π × 4 = 32·π.
