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.

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.

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.

Kami is in charge of creating a five-digit code to lock and unlock a secure chamber. She can use any digit from 0 through 9, and she can use each digit as many times as she wants. She knows she wants to start the code with an even number.
How many possible codes that start with an even number could Kami create?
40,000 codes
50,000 codes
400,000 codes
500,000 codes
We will see that there are 50,000 different possible codes that start with an even number.
How many possible codes are there?
We know that the code has 5 digits, each one with 10 possible options (except the first one, when we only can use even digits, so there we have 5 options).
And the numbers can be repeated any number of times through the code, then the total number of different codes that can be made is equal to the product between the numbers of options for each of the digits, we will have:
[tex]C = 5*10*10*10*10 = 50,000[/tex]
So there are 50,000 different codes.

The speed that marina can run from the given parameters is; 4 miles per hour
How to Solve Algebraic Problems?Let x be Marina's speed running.
Marina's speed biking is x + 9.
Thus, the time she spent is calculated as;
19.5/(x + 9) = 6/x
Cross Multiply to get;
19.5x = 6(x + 9)
19.5x = 6x + 54
Solving this gives;
x ≈ 4 mph

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

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.

From a rectangular 5×13 piece of cardboard, four congruent squares with sides of length x are cut out, one at each corner. (See the accompanying figure.) The resulting crosslike piece is then folded to form a box. Answer the following.
a) Find the volume V of the box as a function of x.
b) Sketch the graph of y=V(x).
The Dimensions of box be:
L = 2.21406 ftD= 10.78594 ftH = 1.10703 ftVolume, V = 24.4366 ft³What is Volume of Cuboid?The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.
a)Each side of the future box is
L = 5-2x ,D = 13-2x
and let the height of box is x
Then, volume of the box as function of x is:
V(x)= (5-2x)*(13-2x)*x
V(x)= (65-10x-26x +4[tex]x^{2}[/tex])*x
V(x)= 65x-36[tex]x^{2}[/tex]+4[tex]x^{3}[/tex]
Differentiate the above equation, we get
V'(x)= 65-72x+12[tex]x^{2}[/tex]
If V'(x) = 0, then
65-72x+12[tex]x^{2}[/tex]=0
[tex]x_{1,2} = (-b\pm \sqrt{ b^{2} - 4*a*c} ] /2a[/tex]
[tex]x_1[/tex]=4.89297
[tex]x_2[/tex]=1.10703
We will take x= 1.10703
Then the sides of the box are:
L = 5-2(1.10703) = 2.21406 ft
D = 13 - 2*x = 13 - 2x(1.10703)= 10.78594 ft
H = x = 1.10703 ft
Now, volume is
V = 2.21406*10.78594*1.10703 = 24.4366 ft³

y<2x−2
y>2x−2
Answer:
y > -2x + 2
Step-by-step explanation:
The dashed line tells us the answer doesNOT have the "or=to" under the inequality symbol. Then the y-intercept is positive 2. So it must be
y > -2x + 2

Look at the y-intercept and think of up/down instead of left/right on the shading and then you can see whether its < or >
