At 78°F, a certain insect chirps at a rate of 106 times per minute, and at 81°F, they chirp 112 times per minute. Write an equation in slope-intercept form that represents the situation.

Answers

Answer:

y=2x-50

Step-by-step explanation:

[tex]m=\frac{y^2-y^1}{x^2-x^1} = \frac{112-106}{81-78} =\frac{6}{3} =2[/tex]

slope-intercept formula(substitute 81 for x, 112 for y, and 2 for m:

y=mx+b

112=2(81)+b

112=162+b

Then subtract 162 from both sides, and b=-50

Plug in all numbers into original equation

y=mx+b  m=2 b= -50

So u get y=2x-50

Polygon A is a square. Polygon B has 2 more sides than polygon A. What type of polygon is B?
a.
pentagon
b.
decagon
c.
hexagon
d.
octagon


Please select the best answer from the choices provided

A
B
C
D

Answers

The answer is C. If Poly A is a square it has 4 sides. We know that Poly B has 2 more sides than Poly A. So we add 2+4 which is 6. So a 6 sided shape would be a hexagon.
c. hexagon ... a pollygon with 6 sides is a hexagon

Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.

Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.

Answers

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.

Each soda costs $4.50 at the baseball game. Which of the following represents the dependent variable?

Answers

Answer:

The price of the soda.

Step-by-step explanation:

The dependent variable is the variable defined to be dependent on another object, typically the independent variable. That means the variable that varies based off of another value is the dependent variable. In this situation, as the number of sodas bought increases, the total price increases. The price varies off of the number of sodas because the increase in sodas causes it to increase. Thus, the price is the dependent variable.

The dependent variable would be the total cost of the sodas.

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Each soda costs $4.50 at the baseball game.

Here, The cost of the sodas is dependent on the number of sodas purchased, which is the independent variable.

Thus, The dependent variable would be the total cost of the sodas.

What type of stretching should Jake never do? ballistic stretching dynamic stretching static stretching none of the above A Big YearBy Bob KowalskiWould you go to the ends of the earth to see a bird? What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest?If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want.A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. For most in North America who participate in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast.You may be thinking that looking at birds is silly, but just think about the numbers of the recent record holders and the commitment it takes to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune.Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating.This honesty comes from the fact that most people who want to break such a record know the greatest rewards are not necessarily in winning. Such rewards are in being able to commit a year of your life to doing something you love. Rewards are found in seeing amazing, inspiring creatures like the California Condor or the Magnificent Frigate bird. Rewards also come in spending time with people who, like you, want to spend their time looking to the skies and trees for glimpses of emerald, crimson, or cerulean blue feathered jewels.You don't have to be able to travel a continent to have a big birding experience though. Have a big month. Or a big weekend. Set a personal record, learn to identify the species that live in your part of the world, or try to learn the calls of just two species of birds. You will soon find looking at birds isn't such a strange way to spend your time.Extra! Extra! Backyard BirdingMany schools, families, and young birders across the country participate in the "Great Backyard Bird Count." While not as long as a "Big Year," the "Great Backyard Bird Count" happens every year. It depends on birders and families across the country to watch feeders and other areas in their yards and count the number of birds they see. Unlike the "Big Year," the goal is not to see who can count the most birds. Instead, participants in this event work together to help bird experts get a good idea of how birds are doing. Participants are given checklists and enter their sightings on a website. Called a "citizen-science" project, this event is open to anyone, requires no travel, and happens every year over one weekend in February.What is the main point of the paragraph that begins "This honesty comes from" in "A Big Year"? A "Big Year" offers many rewards beyond winning. Beautiful and amazing birds are worthy of searching out. Birds come in many shapes and colors. Breaking records tends to keep people honest.
