Determine whether each infinite geometric series diverges or converges. 1/64 + 1/32 +1/16 + . . . .
A geometric series exist as the totality of an infinite number of terms that contain a constant ratio between consecutive terms.
The infinite geometric series 1/64 + 1/32 +1/16 + . . . . diverges.
What is an infinite geometric series?The result of an endless geometric sequence exists an infinite geometric series. There would be no conclusion to this series. There would be no conclusion to this series. The infinite geometric series has the general form a1 + a1r + a1r² + a1r³+…, where r is the common ratio and a1 is the first term.
The equation be S = a1/(1-r), where s is the total, a1 is the series's first term, and r is the common ratio, is a general formula for calculating the sum of an infinite geometric series. The formula a2/a1, where a2 is the second term in the series and a1 is the first term in the series, can be used to determine the common ratio.
Let the sequence be 1/64 + 1/32 + 1/16 + . . . .
a(first term) = 1/6
r(common ratio) = a2/a1 = (1/32) / (1/64)
= (64/32) = 2
Since, | r | > 1, the infinite geometric series diverges.

A ticket to see your favorite baseball team costs $31.55. That price decreases by $0.21 for every game lost during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 22 games. What is the price of a ticket after the team loses 22 games?
Answer:
The price of a ticket after the team loses 22 games is $26.93
Step-by-step explanation:
Original value = $31.55
value decrease per game lost = $0.21
equation uses C and L
C = 31.55 - 0.21L
22 games lost
C = 31.55 - 0.21(22)
C = 31.55 - 4.62
C = 26.93
C = $26.93

Solve each equation. Check each solution. 2a + 1 / 6 + a/2= a-1/3
The solution of the given equation 2a + 1 / 6 + a/2 = a-1/3 is a = -1
In this question, we have been given an equation.
[tex]\frac{2a+1}{6}+\frac{a}{2} = \frac{a-1}{3}[/tex]
We need to find the solution of given equation.
[tex]\Rightarrow \frac{2a+1}{6}+\frac{a}{2} = \frac{a-1}{3}\\\\\Rightarrow \frac{2(2a+1)+6a}{12}=\frac{a-1}{3}\\\\\Rightarrow \frac{4a+2+6a}{12}=\frac{a-1}{3}\\\\ \Rightarrow \frac{10a+2}{4}=a-1\\\\\Rightarrow 10a+2=4a-4\\\\\Rightarrow 6a=-6\\\\\Rightarrow a=-1[/tex]
We need to check above solution.
Substitute a = -1 in LHS of given equation.
2a + 1 / 6 + a/2
= [2(-1) + 1 / 6] + [-1/2]
= (-1/6 - 1/2)
= -(4/6)
= -2/3
Substitute a = -1 in RHS of given equation.
a-1/3
= (-1 - 1)/3
= - 2/3
So, LHS = RHS
Therefore, the solution of the given equation 2a + 1 / 6 + a/2 = a-1/3 is a = -1

opy the vectors. Then find each sum or difference.
→w + →z
The components of the two vectors are added and subtracted to produce the addition and subtraction vector PQ. i.e. →PQ = →Q + →P and →PQ = →Q - →P
A vector, which denotes the mathematical and geometrical direction of the provided quantity, is a quantity with both magnitude and direction.
For example : Velocity, Displacement etc.
Let's start by assuming that,
P(x,y,z) and Q(u,v,w)
Now, we need to find the vector addition and subtraction
Addition of vectors to give →PQ
→PQ = →Q + →P
= (ui + vj + wk ) + (xi + yj + zk)
= (ui + xi ) +(vj + yj) + (wk +zk)
= (u+x) i + (v + y) j + (w + z)k
= →PQ
Similarly, Subtraction of vectors to give →PQ
→PQ = →Q - →P
= (ui + vj + wk ) - (xi + yj + zk)
= (ui + vj + wk - xi - yj - zk)
= (ui - xi ) +(vj - yj) + (wk -zk)
= (u-x) i + (v - y) j + (w - z)k
= →PQ
For example : Let P(1,2,1) and Q ( -1, -2,4)
Then, Addition →PQ = →Q + →P
= (1i + 2j + 1k ) + (-1i + (-2)j + 4k)
= (1-1) i + (2 -2) j + (1 + 4)k
= oi+0j +5j
= 5j
Subtraction →PQ = →Q - →P
= (1i + 2j + 1k ) - (-1i + (-2)j + 4k)
= (1+1) i + (2 +2) j + (1 - 4)k
= 2i+4j -3j
Hence, the vector PQ addition and subtraction is given by the addition & subtraction of the components of the two vectors.

prove the quadrilateral is a parallelogram by showing opposite sides are congruent A(-7,5) B(6,5) C(4,-2) D(-9,-2)
The quadrilateral is a parallelogram because the pairs of opposite sides of the quadrilateral are parallel, ABCD is a parallelogram.
Given:- A quadrilateral ABCD in which AB=CD and AD=BC.
To prove:- AB∥CD and AD∥BC
Construction:- Joi A and C.
Proof:-
In △ABC and △CDA,
AB=CD(Given)
AD=BC(Given)
AC=AC(Common)
∴△ABC≅△CDA(By SSS)
Therefore, by CPCTC,
∠ACD=∠BAC
∠DAC=∠ACB
Since alternate angles are equal, thus the lines are parallel.
Therefore,
AB∥CD and AD∥BC
Since both the pairs of opposite sides of the quadrilateral are parallel, ABCD is a parallelogram.
Hence proved.
A quadrilateral in geometry may be a four-sided polygon with four sides and four corners (vertices). The Latin words Quadri, a variation of 4, and latus, meaning "side," are the source of the name. In regard to other polygons, it's also known as a tetragon, from the Greek "tetra" for "four" and "gon" for "corner" or "angle" (e.g. pentagon).

Use distributive property to rewrite (3+8)15
By using distributive property 15(3 + 8) 15 11 = 165 both approaches yield the same conclusion.
Distrubutive Property Formula : a(b+c)=a b+a c
The distributive property is also known as the distributive law of multiplication over addition and subtraction. By its very name, the procedure implies that something will be divided or distributed. According to the distributive property, an expression of the form A (B + C) can be resolved as A (B + C) = AB + AC. Subtraction also belongs to the scope of this distributive law, which is expressed as A (B - C) = AB - AC. The distribution of operand A among the other two operands is seen from this.
A (B + C) = AB + AC represents the distributive property of multiplication over addition.
15(3+8) = (15.3) + (15.8)
15.11 = 45 + 120
165 = 165
Using the law of BODMAS, we can now attempt to solve the expression. The solution is as follows. We will first add the figures in brackets, and then we will multiply this total by the figure outside of the brackets.
Hence, using distributive property, it follows that 15(3 + 8) x 15 = 165. As a result, both approaches yield the same conclusion.

Given the statement is five and three-tenths times a number plus two and seven-tenths is less than three and three-tenths times a number plus one and six-tenths.
A mathematical statement is a meaningful component of words that can be true or false. Simply, they are known as a statement.
Let us assume the given number be x.
According to the given statement,
Five and three-tenths of a number means 5.3x.
And two and seven-tenths means 2.7.
So, five and three-tenths times a number plus two and seven-tenths means 5.3x+2.7. ......(1)
It is also given that three and three-tenths times a number means is 3.3x.
And one and six-tenths means 1.6.
So, three and three-tenths times a number plus one and six-tenths means 3.3x+1.6 .......(2)
Now, we will substitute equation (1) less than equation (2) according to the given statement is
5.3x+2.7<3.3x+1.6
Further, we will subtract 2.7 from both sides, we get
5.3x+2.7-2.7<3.3x+1.6-2.7
5.3x<3.3x-1.1
Now, we will subtract 3.3x from both sides, we get
5.3x-3.3x<3.3x-1.1-3.3x
2x<-1.1
Now, we will divide both sides by 2, we get
2x/2<-1.1/2
x<-0.55
