Step-by-step explanation:

Finding the common difference :

20 - 137

Formula :

aₙ = aₙ₋₁ + 7
Answer 2

Answer:

[tex]\large \boxed{\sf 7n + 6}[/tex]

Explanation:

Sequence: 13, 20, 27,...

Find common difference: second term - first term = 20 - 13 = 7

As it is an explicit arithmetic term:

⇒ a + (n - 1)d             (a is the first term, d is common difference)

⇒ 13 + (n -1)(7)

⇒ 7n - 7 + 13

⇒ 7n + 6

Answer:

x = 17   degrees        y = 3  units

Step-by-step explanation:

Since angle   F  and  E are equal,   sides  DE  and  DF   are equal and you now have an equilateral triangle

  each angle is   60 degrees    so   4x - 8 = 60    shows   x = 17

   since the sides are equal :   8y-3 = 6y+3   shows y = 3  

Answer:

x = 17 , y = 4

Step-by-step explanation:

since EF and DF are congruent , then

8y - 5 = 6y + 3 ( subtract 6y from both sides )

2y - 5 = 3 ( add 5 to both sides )

2y = 8 ( divide both sides by 2 )

y = 4

--------

the triangle has 3 congruent angles , then

3(4x - 8) = 180 ( divide both sides by 3 )

4x - 8 = 60 ( add 8 to both sides )

4x = 68 ( divide both sides by 4 )

x = 17

The equation d = 11 cosine (startfraction 8 pi over 5 endfraction t) models the horizontal distance, d, in inches of the pendulum of a grandfather clock from the center as it swings from right to left and left to right as a function of time, t, in seconds. according to the model, how long does it take for the pendulum to swing from its rightmost position to its leftmost position and back again? assume that right of center is a positive distance and left of center is a negative distance.

Answers

The time that is taken for the pendulum to swing from its rightmost position to its leftmost position and back again is 1.25 seconds

Calculations and Parameters:

Given that this is a cosine equation,

At maximum, Cos (0) =1

At minimum, Cos (π) = -1.

Hence,

At the maximum:

8π/5 t = 0t = 0

At the minimum:

8π/5 t = πt = 5/8t = 0.625

Given that the time taken from max to min is 0.625 and also to min to max is also 0.625,

The total time taken would be:

0.625 + 0.625 = 1.25s

What is prime factorization?

Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.

For an integer, factorization is the decomposition of that integer in terms of smaller integers which when multiplied with each other give back that considered number.

Those composing integers are called factors of that considered integers.

Prime factorization is when all those factors are prime numbers.

Thus, prime factorization expresses an integer in terms of multiples of prime numbers.

∠AOB = 15°

∠BOC = 165°

Step-by-step explanation:

Angles on a straight line add up to 180°

[tex]\sf \implies \angle AOB + \angle BOC=180[/tex]

Substitute the given expressions for the angles:

[tex]\sf \implies (2x - 15) + 11x = 180[/tex]

Collect and combine like terms:

[tex]\sf \implies 2x +11x- 15=180[/tex]

[tex]\sf \implies 13x- 15=180[/tex]

Add 15 to both sides:

[tex]\sf \implies 13x- 15+15=180+15[/tex]

[tex]\sf \implies 13x=195[/tex]

Divide both sides by 13:

[tex]\sf \implies \dfrac{13x}{13}=\dfrac{195}{13}[/tex]

[tex]\sf \implies x=15[/tex]

Now substitute the found value of x into the expressions for each angle:

[tex]\sf \implies \angle AOB =2(15)-15=15^{\circ}[/tex]

[tex]\sf \implies \angle BOC =11(15)=165^{\circ}[/tex]

Answers

Answer:

m = 1

c = 4

Step-by-step explanation:

First let's review what a slope-intercept form is.

Slope-intercept form is a specific form of linear equations. It always has y on one side and all the other terms on the other. Its structure is:

[tex]y = mx + c[/tex],

where m is the slope and c is the y-intercept.

You can easily read slope (m) and intercept (c) in your equation.

[tex]y = mx + c\\y = x + 4[/tex]

You can see that m in front of x is 1, because x = 1x. Multiplying with 1 perserves the number.

So:

[tex]m = 1\\c = 4[/tex]

How do I solve x - 6 1/2 = 3 2/3
Pls explain ur answer and how I can improve I’m having math finals

Answers

Answer:

10 1/6

Step-by-step explanation:

First, you need to turn all the mixed numbers into improper fractions. You do this by multiplying the whole number by the denominator, adding the numerator, and then putting that number over the denominator.

So, 6 1/2 would become (6(2) + 1)/2 = 13/2. And 3 2/3 would become (3(3) + 2)/3 = 11/3.

Then, you can rewrite your equation using the improper fractions:

x - 13/2 = 11/3

Then, add 13/2 to both sides since it is being subtracted:

x = 13/2 + 11/3

Add the fractions by multiplying the denominators of each by the fraction of the other:

3(13/2) = 39/6
2(11/3) = 22/6

Add the fractions:

39/6 + 22/6 = 61/6

Simplify the fraction:

If you have to find x in a question which is having Subtraction, then you add what number was being subtracted or what was subtracting the x or variable with the ending result.  If you're doing addition, then you do subtraction in the same way.

Multiplication -> Division

Divisioin -> Multiplication

these 2 also in the same way!

Why do to do this?

Because when we will add that number with the final result, then we will get what is x, since x-that number = the last number. Try to understand, it's pretty hard to explain.

Now, solving the problem!
