Suppose that x and y are related by the equation y = 1100 + 15x.Answer the questions below.What is the change in the total cost for each book printed?What is the cost to get started (before any books are printed)?

Answer: 17

Step-by-step explanation:

A puzzle, defined as "anything which baffles or perplexes," refers to an enigma or a conundrum that requires creative thinking to solve.

The answer is A = 7.

A puzzle, defined as "anything which puzzles or perplexes," refers to a riddle or issue that defies creativity to be solved.

Retaining mental quickness and short-term memory while working on a puzzle strengthens connections between brain cells.

Dopamine, a neurotransmitter that controls mood, memory, and focus, is produced more readily as a result of solving puzzles.

Every time we complete the puzzle, dopamine is produced.

Given the puzzle condition,

The sum of any 3 consecutive digits must be 17.

Given numbers 8, 2

So the third number would be 8 + 2 + A = 17

10 + A = 17

Therefore A is 17-10 = 7

A = 7

An equation or inequality to model the situation: The distance d to school is 1 1/2 miles more than the distance p to the park is  d = p + 3/2

a statement that the values of two mathematical expressions are equal indicated by the sign =, is known as equation.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is known as inequality.

For this situation, we would assume that both the distances i.e 'd' and 'p' are in miles.

It is mentioned that the distance d is more than the distance p by 3/2 miles.

It means that if we add  3/2 miles to the distance 'p' the output will be distance 'd'

The equation for this is as follows :- d = p + 3/2

It also means that if we substract 3/2 miles from distance 'd', the output will be distance 'p'

The equation for this is as follows :- p = d - 3/2

But we are asked in the situation that distance d is more than than the distance 'p'.

Therefore , an equation or inequality to model the situation: The distance d to school is 1 1/2 miles more than the distance p to the park is d = p + 3/2.

Answer:

R=100%

Step-by-step explanation:

Here

Increased population (Pt) = 5.2-2.6 = 2.6

Time = 1987-1952

Rate of increase=?

By formula

Pt = P(1-R/100)^t

2.6=2.6(1-R/100)^35

1=(1-R/100)^35

0^35 = (1-R/100)^35

0=1-R/100

0= 100-R

R=100%

so the average annual population growth rate of the world between 1952and1987 is 100%

2 divided by 13

Using the Factor Theorem, the polynomial with real coefficients that has zeros -1 and 2 - 3i is given by:

f(x) = x³ - 3x² + 9x + 13.

The Factor Theorem states that a polynomial function with roots(also called zeros) [tex]x_1, x_2, \codts, x_n[/tex] is given by the following rule.

[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]

In which a is the leading coefficient of the polynomial, determining if it is positive(a positive) or negative(a negative).

Considering a leading coefficient of a = 1, the zeros of the polynomial are given as follows:

Hence the polynomial is given by:

f(x) = (x + 1)(x - 2 + 3i)(x - 2 - 3i)

f(x) = (x + 1)[(x - 2)² - (3i)²]

f(x) = (x + 1)(x² - 4x + 13), as (3i)² = 9i² = 9(-1) = -9, -(-9) = 9.

f(x) = x³ - 3x² + 9x + 13.

The total probability that a king and pawn are selected without replacement is  1 / 31 .

The area of mathematics known as probability primarily deals with numerical(fractions or decimals) representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Sample space = 32 (16 black and 16 white pieces)

number of kings in the set = 2

Probability that a king is selected first

P(king) = 2 ÷ 32 = 1 / 16

Now the total number of pieces left = 32 - 1 = 31

number of pawns = 8+8 =16

Probability that a pawn is selected = 16 ÷ 31

P(pawn) = 16/31

Now the total probability that a king and pawn are selected without replacement = P(king) × P(pawn) = 1/16 × 16/31 = 1 / 31

Therefore the required probability is 1 / 31 .

Answer:

difference = 6 feet 5 inches

Step-by-step explanation:

The longest shot put throw by a boy is given as 25 feet 8 inches . The longest shot put throw by a girl is given as 19 feet and 3 inches. The number of times the longest shot put throw by a boy is greater than by a girl can be computed as follow.

The question asked us to find the difference between the throw. The difference between the throw is the boy throw minus the girls throw. Mathematically,

The longest boys throw = 25 feet 8 inches

The longest girls throw =  19 feet 3 inches

difference = The longest boy throw  - The longest girl throw

difference =  25 feet 8 inches -   19 feet 3 inches

difference = 6 feet 5 inches

In linear equation, 3464.1016 feet  is the shortest length of fence that the Ranch owner can use.

What is linear equation definition and example?

Let L represent the length of the field.

Let W represent the width of the field.

Let F represent the length of fence needed.

L*W=500000

2L+3W=F Both length sides+both width sides+ fence across the width.

Let's look at the first equation again:

L*W=500000

W=(500000/L)

Now we can substitute (500000/L) for W in the second equation.

2L+3(500000/L)=F

2L+1500000/L=F

Now we have a function. We can input any length, and we'll know length needed. But how can we find the length needed so that F is as small as it can be? If you know derivatives, there's an exact way. The next easiest way to do it is to graph.

Manner 1: Derivative

Set the derivative to zero...when the length stops going down and starts coming back up, it'll be at it's lowest point.

2L+1500000^-1=F

F'=2-1500000^-2

0=2-1500000^-2

1500000/(L^2)=2

1500000=2L^2

1500000=L^2

L=866.025

Now, we know that L=500000/W

so 866.025=500000/W

W=500000/866.025

W=577.35027 feet.

Now,

2L+3W=2(866.025)+3(577.35027)

Minimum fencing needed: 3464.1016 feet.

The ratio of the net force to the weight of the scallop (F net/Weight) for this motion exists 792.657 Newtons.

The net force exists the vector sum of all the forces that act upon an object. The total of all forces exerted on an object is known as the net force. A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion. When there are a lot of forces acting on a system, the term "net force" is employed.

Given, mass = 29g, speed = 4.10 m/s , Time = 0.15 s

Acceleration (a ) = (final speed - initial speed)/time taken

                           = 4.10 - 0/ 0.15 = 27.333 m/s/s

F = m × a = 29 g × 27.33 m/s

            =  792.657 Newtons

What is triangle?
Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one. The symbol for an ΔABC triangle is A, B, and C.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.

Let angle b be x

Therefore angle c will also be  x [as given b and c are equal] and angle a will be x - 42°.
Now as we know that the sum of the measures of the angles of a triangle is 180° therefore,

x + x + x - 42° = 180°

=> 3x = 222°

=> x = 74°  which is angle b and c

and angle a is (74 - 42)°  =32°
