It is a downward parabola, which means the height of the ramp decreases as the distance from one side of the ramp increases.
What is the parabola?
A parabola is a symmetric, U-shaped geometric curve that can be defined as the set of all points that are equidistant to a fixed point (the focus) and a fixed line (the directrix). It is a conic section, which means it is the intersection of a plane and a cone. In algebraic terms, a parabola can be defined as the graph of a quadratic equation of the form y = ax^2 + bx + c, where a, b, and c are constants.
The height of a ramp can be modeled by f(x) = -1/2 x − 241 +2, where f(x) is the height of the ramp, in feet, and x is the distance from one side of the ramp. To find the vertex of the parabola, we need to complete the square.
The vertex is located at (-b/2a, f(x) + (b^2-4ac)/4a) = (-1/2, -241 +2) = (0, -240)
This means that the maximum height of the ramp is -240 feet when the distance from one side is 0 feet.
Because the distance cannot be negative, and the ramp is unknown length, the relevant domain is {x | 0 ≤ x ≤ unknown}.
Because the height cannot be negative, and the ramp is unknown tall, the relevant range is {y | 0 ≤ y ≤ unknown }.
The graph is symmetric in the line x = 0. This means that the height from a distance of 0 to an unknown feet away from one side of the ramp is the same as the height from a distance of an unknown to an unknown feet away from one side of the ramp.
It is a downward parabola, which means the height of the ramp decreases as the distance from one side of the ramp increases.

A $900 sound system decreases in value by 9% each year.
y=
Answer:
y = 900(0.91^t)
Step-by-step explanation:
You want a function that describes the value of a $900 sound system that decreases in value by 9% per year.
Exponential functionWhen the amount of change is proportional to the amount, the amount is described by an exponential function:
y = ab^x
where 'a' is the initial value, and 'b' is the "growth factor."
ApplicationHere, the change is expressed as a "growth rate" of -9% per year. The growth factor is 1 added to the growth rate:
b = 1 +(-9%) = 1 -0.09 = 0.91
The initial value is given as ...
a = 900
So the function you want is ...
y = 900(0.91^t)
__
Additional comment
The independent variable in this case is time, and the problem statement tells you to use 't' to represent it. The decay rate is given as a percentage per year, so the units of t will be years.
Max's dad bought his friends 5 bottles of water and 8 slices of pizza at the concession stand and spent $20.25. He had to go back and get 1 more bottle of water and 3 slices of pizza. This time the total was $6.50. What is the cost of one slice of pizza?
Step by step explanation please?!
Using simultaneous equations, the cost of one slice of pizza bought by Max's dad at the concession stand is $1.75.
What are simultaneous equations?Simultaneous equations are two or more equations solved concurrently or simultaneously.
Simultaneous equations are also called a system of equations.
Bottles Slices of Total
of Water Pizza Cost
1st purchase 5 8 $20.25
2nd purchase 1 3 $6.50
Let the cost of bottles of water = b and the cost of slices of pizza = p
Equations:Equation 1: 5b + 8p = 20.25
Equation 2: b + 3p = 6.50
Multiply Equation 2 by 5:
Equation 3: 5b + 15p = 32.50
Subtract Equation 1 from Equation 3:
5b + 15p = 32.50
-
5b + 8p = 20.25
7p = 12.25
p = 1.75
The cost of one slice of pizza (p) = $1.75
Check:
b + 3p = 6.50
b + 3(1.75) = 6.50
b + 5.25 = 6.50
b = 1.25
= $1.25
Thus, the cost of one slice of pizza is $1.75.

The average price of a gallon of milk was $2.78 in 2000 and increased by about $0.11 per year. Write an inequality that could be used to determine the years, y, in which the price of a gallon of milk is between 3 and 4 dollars.
We know that the average price of a gallon of milk in 2000 was $2.78 and that it increased by about $0.11 per year. To find the years in which the price of a gallon of milk is between $3 and $4, we can use the following inequality:
2.78 + 0.11y < x < 4
Where x is the price of a gallon of milk in a given year y, and y represents the number of years since 2000.
The inequality can also be written as:
2.78 + 0.11y < x < 4
That can be simplified as
y > (3-2.78) / 0.11 = (0.22) / 0.11 = 2
y < (4-2.78) / 0.11 = (1.22) / 0.11 = 11
So, the years in which the price of a gallon of milk is between $3 and $4 are y > 2 and y < 11

Amount paid by each student = Rs.45765 / 150 = Rs.305
The school contributed an extra 1.7%. for the payment order on top of the registration fee of Rs. 45000.
To find the total amount paid by the school, we need to calculate the additional amount and add it to the registration fee:
Additional amount = (1.7/100) * 45000 = Rs. 765
Total amount paid by the school = registration fee + additional amount = 45000 + 765 = Rs.45765
To find the amount paid by each student, we need to divide the total amount paid by the school by the number of students:
Amount paid by each student = total amount paid by the school/number of students

The perimeter of the given polygon is about 16.4 units.
How to find the perimeter of the polygon?We want to find the perimeter of the polygon whose vertices are (-3, 2), (2, 2) and (-1, -3).
The perimeter will be equal to the sum of the distances between the vertices, and remember that the distance between two points (x₁, y₁) and (x₂, y₂) is:
d = √( (x₂ - x₁)² + (y₂ - y₁)²)
The distances are:
between (-3, 2) and (2, 2)
d = √( (-3 - 2)² + (2 - 2)²) = 5
between (-1, -3) and (2, 2)
d = √( (-1 - 2)² + (-3 - 2)²)
d = √( 9 + 25) = 6
between (-1, -3) and (-3, 2)
d = √( (-1 + 3)² + (-3 - 2)²)
d = √29 = 5.4

How to find the linear function?A general linear equation can be written as:
y = m*x + b
Where m is the slope and b is the y-intercept.
And two lines are perpendicular if the product between the slopes is -1, then if we want to find a line perpendicular to:
y = 1/2x - 4
Then the slope m must be sch that:
m*(1/2) = -1
m = -2
Then the line is like:
y = -2*x + b

any negative exponent of 1.3 means we have to consider it as 1/1.3 with the positive exponent.
so, if the given temperature (x) is negative, 1.3 has a positive exponent and gets bigger and bigger the lower (smaller) x gets.
if the given temperature (x) is positive, 1.3 has a negative exponent and gets smaller and smaller the higher (bigger) x gets.
the domain is the interval or set of all valid x-values.
there is no need for any restriction for x.
so, the domain is all real numbers.
the question is : up to what temperature will there be heating ?
at 5°C ? yes, sure.
at 10°C ? yes, sure.
at 15°C ? some people still need heating.
at 20°C ? most likely not.
but f(20) = $0.042094266... ≈ $0.04
so, still a tiny little bit of heating is happening for the function, but in reality most likely not at all.
the information about such a limit is missing in the question. so, again no limit for x.
f(-8) means that x = -8.
f(-8) = 8(1.3)^--8 = 8(1.3)⁸ = 8×8.15730721 =

Assume that log₂(7) is rational. This means that it can be written as the ratio of two integers, a/b, where a and b are integers and b is not equal to zero.
Then, using the definition of a logarithm, we have: 2^(a/b) = 7
Multiply both sides by b, we have: 2^a = 7b
