Which answer describes the sequence {1,3,7,15,…} as a mathematical statement?

Answers

Answer:

so just successive powers of 2

Step-by-step explanation:

1, 3, 7, 15, 31, 63, _? Add successive powers of 2 to the number: 1+2=3; 3+4=7; 7+8=15; 15+16=31; 31+32=63; 63+64=127.

The given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

Given that,

To justify the given sequences 1,3,7,15.

What is arithmetic progression?

Arithmetic progression is the series of numbers that have common differences between adjacent values

What is geometric progression?

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Given a sequence, 1,3,7,15
where first term A0 = 1
second term A1 = 1 + 2 = 3
third term A2 = 3 + 4 = 7
From above sequence we can conclude the general term for the sequence as, S = A(n-1) + (A(n-1) + 1)

Thus, the given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

the next algebra test is worth 100 points and contains 35 problems. multiple-choice questions are worth 2 points each and word problems are 7 points each. how many of each type of equation are there? Please leave steps.

Answers

Answer:

29 multiple choice questions, 6 word problems

Step-by-step explanation:

2x + 7y = 100

x + y = 35

y = 35 - x

2x + 7 (35 - x) = 100

2x - 7x + 245 = 100

-5x = -145

x = 29

29 + y = 35

y = 6

Find the solution to the system: y=4x and 3x+2y=55

Answers

Answer:

x = 5, y = 20

Step-by-step explanation:

if y = 4x and 3x+2y = 55 then we can subtitude y as x.

We know that y = 4x so we can write 4x wherever we see y.

3x + 2y = 3x + 2(4x) = 55

3x + 8x = 55

11x = 55

x = 5.

And if y = 4x = 4(5)

y = 20

What is the equation of the line perpendicular to Y= 1/2x +6 that passes through the point (4,1)

Answers

Answer:

Step-by-step explanation:

y= mx+b is the general equation where m is the slope

y= 1/2 x +6 has the slope 1/2

perpendicular lines have the slope negative reciprocal

so the slope of the ⊥ line is -2

y = -x +b , yet for point (4, 1) the x=4 and y =1

1= -4 +b so b= 5

the equation of the ⊥ line is y= -2x+5
