The function f(x) is shown on the graph.
The graph shows an L-shaped curve, which follows along the x-axis from the left, but is not touching it. It crosses through 0 comma 1 to and then increases upward in quadrant one.

Which type of function describes f(x)?
Rational
Polynomial
Logarithmic
Exponential
Considering that the graph contains an asymptote and does not cross it, an exponential function is modeled.
What is an exponential function?It is modeled by:
[tex]y = ab^x + c[/tex]
In which:
a is the y-intercept.b is the rate of change.y = c is the asymptote, which is not crossed by the function.Hence, in this problem, an exponential function with asymptote at y = 0 is modeled by the graph.

Sam traveled 20 miles in 3 hours.
Sam walked part of the distance at a speed of 4 miles per hour.
Sam rode his bicycle for the remaining distance at a speed of 12 miles per hour.
note: this question has been asked before but i do not believe it was answered correctly, it was solved using 4 hours instead of 3
Answer:
see below
Step-by-step explanation:
distance / rate = time
x = walking distance 20 -x = biking distance
x / 4 m/hr + (20-x) / 12 m/hr = 3 hours
x/4 + ( 20-x) /12 = 3 multiply both sides of the equation by 12
3x + 20 -x = 36
2x = 16
x = 8 8 miles walking then 12 miles biking

The composite figure shown is made
from a rectangle and part of a circle. Find the approximate area and
perimeter of the entire figure. Round to the nearest tenth
The area of a 2D form is the amount of space within its perimeter. The area of the composite figure is 74.137 ft².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the composite figure will be the sum of the area of the rectangle and the area of the semi-circle, therefore, the area of the composite figure will be,
Area = Area of rectangle + Area of the hemisphere
= (10×6) + [(π/2)×3²]
= 60 + 14.137
= 74.137 ft²
Hence, the area of the composite figure is 74.137 ft².

Y=45(1.82)x does change represent decay or growth and %increase
Answer:
Exponential growth
The growth rate is 82%
=========================================
Explanation:
Anything of the form y = a*b^x will have the value of b directly determine the growth or decay rate. The value a = 45 is ignored.
Set b = 1.82 equal to 1+r and solve for the variable r.
1+r = 1.82
r = 1.82-1
r = 0.82
The growth rate is 82%
If r was negative, then we'd have exponential decay instead.
Helpppp Asap !!! Which choice could be used in proving that the given triangles are similar?
Answer:
C. [tex]\frac{PQ}{DE} =\frac{4}{6}[/tex]
Step-by-step explanation:
[tex]\frac{PQ}{DE}[/tex] shows similarity in the triangles because they are of the same side of the triangles. PQ = 4, and DE = 6. Option C is the only choice that has these values correctly, so that is the answer.
Option A is incorrect because PQ does not measure 6 cm, and DE does not measure 4 cm. It's the other way around.
Option B is incorrecy because PQ and EF are not of the same side, and EF also had no measurement.
Option D is incorrect because PR and DE are not of the same side either.

Explain how you can graph points on a coordinate plane to create geometric figures such as squares, triangles, rectangles, and parallelograms
A figure can be graphed on a coordinate plane as a set of points located on specific places, specified by their coordinates.
How can we perceive cartesian coordinate plane?The cartesian coordinate plane (2d) is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.
It is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.
On an infinite 2d plane, any 2-dimensional figure can be drawn. Any figure, when drawn, the points constituting that figure can be specified using coordinates. Thus, that figure can be graphed on a coordinate plane as a set of points located on specific places, specified by their coordinates.

3) Ash decided to buy some new socks. They had two coupons, one said 10% off and the other was for $3 off. If the package of socks sells for $25, which coupon should they use? For each option, what would be the price after discount and tax that Ash would need to pay?
Answer:They should use the $3 off
Step-by-step explanation:
10% of 25 = 2.5
25-2.5 = 22.5 (price after using coupon)
$3 off of 25= 25-3
= 22
therefore, if they use the $3 off, they will spend less

The volume of this cone is 19,292.16 cubic yards. What is the height of this cone?
Answer:
The formula for volume of a cone is area of a circle times height, divided by 3.
Therefore volume is pi times radius squared times height, divided by 3.
V = (3.14)(14)^2 (14)/3
V = (3.14) (196)(14)/3
V = (3.14) (2744)/3

Population is growing, which creates more demand for water, especially in the southwestern part of the United States. In general, states are using more water than the system can supply, diminishing this limited resource.
Utilize the Chapter 11 textbook reading, which covers concepts related to common resources such as water and the tragedy of the commons, as well as the podcast "Water in the West: Bankrupt?" provided in the topic Resources to address the following:
• How would water bankruptcy work? Include who benefits and who loses as a result.
• Provide an alternative way in which a water shortage problem can be resolved?
Water bankruptcy is associated with the problems among the beneficiaries whose demands are more than the total available water.
What is water?It should be noted that water simply means a colorless and odorless liquid that is the basis of living organisms. The limited water supply has led to water resources bankruptcy which is the failure of water to meet the imposed demand by users.
The people who will benefit in water bankruptcy are the people whose needs weren't met by the available water.
An alternative way in which a water shortage problem can be resolved is the recycling of waste water and rainwater harvesting.

Maine can be modeled by y = 5 - 3cos (pi/6t) where y is the water depth
in feet and t is the time in hours. Consider a day in which t=0

a. For that day (in 24 hours), when do the high and low tides occur?
b. What are the respective depths of the ocean at high tides and low
tides?
a)The high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.
b)The respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.
What exactly is a function?A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.
Modeling the depth of the Atlantic Ocean at a channel buoy off the coast of Maine is;
[tex]\rm y = 5-3 cos (\frac{\pi}{6} t)[/tex]
a) High tide's value of 'y' when the value of y is maximum. value of cosine is minimum.
The minimum value of cosθ = 1.
The standard form to write the cos function is as;
θ=(2n+1)π
Whenever. high tides occur when it equals odd multiples of π. Similarly, at a Value of even multiples of even function, low tides are at their peak.
Hence,the high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.
At high tide;
соsӨ = - 1 (min value)
y= 5-3(-1)
y = 5+3
y=8 ft
At low tide,соsӨ = + 1 (max value)
y =5-3(1)
y= 5-3
y= 2
Hence,the respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.
