Other rule is that the angle on top of the line should equal 180. Like angle 3 + 79.4+37.3 should equal 180.
Same thing with the angle 4: 180-37.3= 142.7
Next the middle part is a triangle. Sum of all 3 angles should be 180. 79.4+37.3 + angle 1 needs to equal 180.

Answers
The length of this pendulum that makes one full swing is 3.93 meters.
How to calculate the length of the pendulum?Mathematically, the time taken by this pendulum is given by this formula:
[tex]\rm T=2\pi \sqrt{\dfrac{L}{32}}[/tex]
Making L the subject of the formula, we have:
[tex]\rm T=2\pi \sqrt{\dfrac{L}{32}}\\\\32T^2=4\pi ^2L\\\\L=\dfrac{32T^2}{4\pi ^2}\\\\[/tex]
Substitute all the values in the formula
[tex]\rm L=\dfrac{32T^2}{4\pi ^2}\\\\ L = \dfrac{32 \times 2.2^2}{4 \times 3.14 ^2\\}\\\\ L =\dfrac{154.88}{39.43}\\\\L=3.93 \ m[/tex]
Hence, the length of this pendulum that makes one full swing is 3.93 meters.

The correct option isn't shown on the image. I have attached a DESMOS graph with the option listed, and added an approximate equation that comes close to the actual line. This should aid in understanding the equations and lines.
Step-by-step explanation:
See attached image.
The one option is noted as the first equation. I added two points from the line provided: (0,-2.5) and (3.5,0) and then approximated an equation that comes closer. I simply chose 3x-4y=>10, and it comes close to the actual line that goes through the two given points.
To do this properly, find the equation, y=mx+b, of the given line using the two points selected:
Slope, m is rise/run:
Rise = 2.5
Run = 3.5
Slope = 2.5/3.5
y-intercept, b, is -2.5
The equation of the given line is y = (2.5/3.5)x - 2.5
We can rewrite this in the form the answer options are given, or rearrange the answer options to standard form in order to make the comparison.
Hopefully this will help guide to the correct solution.
what are the answers to both of the questions
Answers
Answer:
see explanation
Step-by-step explanation:
(1)
f(x) = g(x) , that is
- x² + 3x - 2 = - x + 1 ( add x to both sides )
- x² + 4x - 2 = 1 ( subtract 1 from both sides )
- x² + 4x - 3 = 0 ( multiply through by - 1 )
x² - 4x + 3 = 0 ← in standard form
(x - 1)(x - 3) = 0 ← in factored form
equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 3 = 0 ⇒ x = 3
(2)
let x and y be the 2 numbers : x > y , then
x + y = 217 → (1)
x - y = 85 → (2)
add the 2 equations term by term to eliminate y
2x + 0 = 302
2x = 302 ( divide both sides by 2 )
x = 151
substitute x = 151 into (1)
151 + y = 217 ( subtract 151 from both sides )
y = 66
the 2 numbers are 66, 151

Which of these expressions represent the
sum of the areas of the triangles shown?
Answers
Answer:
C. 3((x+4) + (x-2))
Step-by-step explanation:
Area of a triangle: [tex]\frac{1}{2}bh[/tex]
Area of the left triangle:
[tex]\frac{1}{2}(x+4)(6)[/tex]
The 6 multiplied by the 1/2 equals 3, so:
[tex]A = 3(x+4)[/tex]
Area of the right triangle:
[tex]\frac{1}{2}(x-2)(6)\\[/tex]
Again, the 6 multiplied by the 1/2 equals 3, so:
[tex]A= 3(x-2)[/tex]
Adding the two areas together equals:
[tex]3(x+4) + 3(x-2)[/tex]
We can factor out the 3 from both, giving us the final answer:

Probability of an event is the measure of its chance of occurrence. The correct probabilities are:
P(A|C) = 2/3P(C) = 3/7How to interpret conditional probabilities?Suppose that the sample space is S. Out of which there are two events, A and B, subsets of S.
Then, we can interpret P(A|B) as the probability of that part of A which is in B, with the new sample space as B. (assuming probabililty of B isn't 0).
Symbolically, we write it as:
[tex]P(A|B) = \dfrac{P(A \cap B)}{P(B)}[/tex]
What is the size of the union of three sets?For three sets, A, B and C:
[tex]n(A \cup B \cup C) = n(A) + P(B) + P(C) - n(A\cap B) - n(A \cap C) - n(B \cap C) + n(A \cap B \cap C)[/tex]
The problem is incomplete. The corresponding venn diagram is attached below.
We can symbolize the venn diagram as:
[tex]n(A) = 12+8+6+5 =31\\n(B) = 11+8+5+3 = 27\\n(C) = 4+8+6+3 = 21\\n(A \cap B) = 5+8=13\\n(B\cap C) = 3+8=11\\n(A \cap C) = 6+8=14\\n(A \cap B \cap C) = 8[/tex]
S = sample space = collection of all unique elements.
S is union of A, B and C.
[tex]n(S) = n(A \cup B\cup C) = 31 + 27 + 21 -13-11-14+8 = 49[/tex]
Checking all the options for their correctness:
P(A|C) = 2/3We have:
[tex]P(A|C) = P(A\cap C)/P(C) = \dfrac{n(A\cap C)/n(S)}{n(C)/n(S)} = \dfrac{n(A \cap C)}{n(C)} = \dfrac{14}{21} =\dfrac{2}{3}[/tex]
Thus, its correct.
P(C|B) = 8/27[tex]P(C|B) = P(C\cap B)/P(B) = \dfrac{n(C\cap B)/n(S)}{n(B)/n(S)} = \dfrac{n(C \cap B)}{n(B)} = \dfrac{11}{27} \neq \dfrac{8}{27}[/tex]
Thus, this option is incorrect.
[tex]P(A) = \dfrac{n(A)}{n(S)} = \dfrac{31}{49} \neq \dfrac{31}{59}[/tex]Thus, this option is incorrect.
P(C) = 3/7[tex]P(C) = \dfrac{n(C)}{n(S)}= \dfrac{21}{49} =\dfrac{3}{7}[/tex]
Thus, its correct.
P(B|A) = 13/27[tex]P(B|A) = P(B\cap A)/P(A) = \dfrac{n(B\cap A)/n(S)}{n(A)/n(S)} = \dfrac{n(B\cap A)}{n(A)} = \dfrac{13}{31} \neq \dfrac{13}{27}[/tex]

y=
Answers
Answer:
y = 8
Step-by-step explanation:
Hi there!
We are given the equation 5y + 2 = 42
And we want to solve it for y
To do that, we need to isolate the variable y on one side - we don't want any numbers on the same side as y.
So we need to first get rid of any numbers on the same side as y; we can subtract 2 from both sides to remove it from the left side.
5y + 2 = 42
-2 -2
_______________
5y = 40
Now, we have variables on one side and numbers on another, but we're not done yet, as we want the value of just y, not 5y (that's 5 * y)
So to find the value of just y, divide both sides by 5
5y = 40

Step-by-step explanation:
Given:

[tex]\implies (7x - 8)= (6x + 17)[/tex]
Open the parenthesis:
[tex]\implies 7x - 8= 6x + 17[/tex]
Add 8 both sides:
[tex]\implies 7x - 8 + 8= 6x + 17 + 8[/tex]
Simplify both sides:
[tex]\implies 7x = 6x + 25[/tex]
Subtract 6x both sides:
[tex]\implies 7x - 6x = 6x - 6x + 25[/tex]
Simplify both sides:
[tex]\implies x = 25[/tex]
Answer:
x = 25
Step-by-step explanation:
Putting Both angels together:
Since,
m∠A = (7x - 8)°
m∠B = (6x + 17)°
Then,
(7x-8) = (6x+17)
Solving for x:
7x - 8 = 6x + 17

7x = 6x + 25

x = 25
