Pickles eat 2 cups of hungry hound dog food each day.
brittany wants to know how many days she can feed pickles from a 14-cup bag of hungry hounds.
We need to find the number of days d she can feed pickles from the bag.
Number of days = d,
So, Every day, Pickles consumes 2 cups of Hungry Hound dog chow.
Pickles then consume cups of Hungry Hound dog chow every day for a few days.
Then,
2*d = 14

A child grew 2 inches this year and 1 inch last year. Height is a function of time.
A movie director makes 2 movies per year. The number of movies is a function of the years.
2 Answers:
Choice C and choice E
======================================================
Explanation:
Choice A is ruled out because of the phrasing "rises and falls". A linear function can't do both rising and falling. You must only pick one direction to aim for. Choice B is ruled out for similar reasoning. A parabola is likely a better option for choice B.
Choice C is linear assuming the car stays at 55 mph. Recall that distance = rate*time. In this case, the equation is y = 55x where x is the number of hours and y is the distance traveled in miles. As an example, x = 10 hours leads to y = 550 miles traveled.
Choice D isn't linear. The increase of 2 doesn't match with the increase of 1. Linear functions must have the same amount of increase over the same time gap.
Choice E is linear and the equation is y = 2x, where x is the number of years and y is the number of movies made total. For example, at year x = 10, the director has made y = 2x = 2*10 = 20 movies total.
---------------
If in doubt, graph the situation. If you get a straight line, then the equation is linear.

Show that these two lines are parallel.
Answer:
They are parallel because they both have the same gradient of 5.
Step-by-step explanation:
For lines to be parallel they need to contain the same gradient.
1. therefore we rearrange the second equation to get y the subject so it's in the format of y=mx+c
2. 2y-10x+3=0
- we +10x and -3 on both sides to get y on its own
2y=10x-3
- we divide each side by 2 as we want y not 2y
y=5x-[tex]\frac{3}{2}[/tex]
3. From this we can see that both the equation contains the same gradient (5)

Part A: Given cosine of theta is equal to radical 2 over 2 comma determine three possible angles θ on the domain [0,∞). (5 points)
Part B: Given θ = 585°, convert the value of θ to radians and find sec θ. (5 points)
a) The angles associated with the cosine function are θ₁ = 45°, θ₂ = 315° and θ₃ = 405°.
b) The secant function of 585° is equal to - √2.
How to determine the value of a trigonometric function associated with a given angle
Graphically speaking, trigonometric functions are relations between two sides of a right triangles related to an angle. There are six trigonometric functions: (i) Two fundamentals (sine, cosine), (ii) Four derivates (tangent, cotangent, secant, cosecant). In the first part, we need to find all the possible angles such that the following trigonometric function is met:
cos θ = √2 / 2
The angles are located in the first and fourth quadrants, respectively. The solutions are θ₁ = 45°, θ₂ = 315° and θ₃ = 405°, respectively.
Now, we need to determine the secant function of 585°. Since the secant function has period of 360°, then we must find an angle coterminal to 585° that is between 0° and 360°:
θ' = 585° - 360°
θ' = 225°
And the trigonometric function is rewritten in terms of fundamental trigonometric functions:
x = 1 / cos θ'
x = 1 / cos 225°
x = 1 / (- √2 / 2)
x = - 2 / √2
x = - √2
The secant function of 585° is equal to - √2.

a polygon is a 2d shape with all straight edges. show via induction that the sum of the interior angles of a polygon with n sides is (n −2) ×180◦. don’t include unneeded base cases. hint 1: it is helpful to know that a triangle’s interior angles always sum to 180◦. you may assume this is true for the problem. hint 2: in order to apply your inductive hypothesis to a polygon, you’ll need to think of it in terms of a smaller polygon. how can you make a smaller polygon out of a big one?
Using the process of induction we can prove that the sum of all angles of a polygon is (n −2) ×180°
In geometry, a polygon is a planar shape characterized by a finite number of segmented straight lines linked to form a network of closed polygons (or polygonal circuit). A polygon is defined as either a bounded plane region or a bounding circuit.
Sum of all angles of a triangle is 180°
Sum of all angles of a quadrilateral is 360°
We know that a triangle has 3 sides.
Hence (n −2) ×180 for n=3 given 180
and (n −2) ×180 for n=4 gives 360.
So we can say that the formula holds by the properties of induction.
The portions of a polygonal circuit are known as its margins or sides. A polygon's vertices or corners are the points where two edges meet. The inside of a solid polygon is sometimes referred to as its body. An n-gon appears to be a polygon with n sides, similar to a triangle, which is a 3-gon.
Hence the formula (n −2) ×180◦ holds for induction.

It is given that a = 30°. It is also shown that C is a right angle, thus c = 90°. The interior angles of a triangle always add up to 180°. So:
a + b + c = 180

b + 120 = 180
b + 120 - 120 = 180 - 120

The local bakery sells both strawberry and chocolate cupcakes. The ratio to strawberry cupcakes to chocolate cupcakes is 8:4. If they baked 240 strawberry cupcakes How many chocolate cupcakes did they bake?
The local bakery baked 120 chocolate cupcakes
The ratio of the strawberry cupcake to chocolate cupcake = 8:4
Number of strawberry cupcakes baked = 240
Ratios: Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other.
Let x represent the total number of cupcakes baked by the bakery
The Sum of the ratio is 8+4 = 12
So, the fraction of strawberry cupcakes baked = 8/12
The total number of cupcakes:
= 8/12 of x =240
8/12x = 240
x = 240*12/8
= 360
So, the number of chocolate cupcakes = 4/12 of 360

Two years ago, a car was valued at $24,000. This year, the value of the car is $23,160. What was the percent decrease in the value of the car?
The value of the car is decreased by 3.5%.
A figure or ratio stated as a fraction of 100 is called a percentage. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
The value of the car two years ago was $24,000.
The value of the car this year is $23,160.
The decreased value of the car after two years will be:
= $24,000 - $23,160
= $840
Let y be the percentage by which the value of the car decreased,
y = 840/24000
y = 0.035
y = 3.5/100
y = 3.5%
The value of the car decreased by 3.5 percent in two years.

4x-2y=-40 liner equation
Solving Linear equation 4x-2y= -40 : x = 10 + 0.5y
What is Linear Equation?
A linear equation is a mathematical expression that may be written as x 1+ldots +a n+x n+b=0, where x 1, ldots, and x n are the variables and displaystyle b, a 1, ldots, and a n are the coefficients, which are frequently real integers.
Simplifying
4x + -2y to 40
Solving
4x + -2y = 40
fixing the 'x' variable.
x should be moved to the left of all terms, and the right of all other terms.
To each side of the equation, add "2y."
4x + -2y + 2y = 40 + 2y
combining similar terms
-2y + 2y = 0
4x + 0 = 40 + 2y
4x = 40 + 2y
Multiply each side by "4".
x = 10 + 0.5y
Simplifying
x = 10 + 0.5y
Hence, solving for x the value of x = 10 + 0.5y
