In advertising, the decay factor describes how an advertisement loses its effectiveness over time. In math, would you expect a decay factor to increase or decrease the value of y as x increases?
When the value of x will increase then decay factor will decrease the value of y.
Given that the decay factor describes how an advertisement loses its effectiveness over time.
Exponential decay will tell us the process of reducing an amount by a consistent percentage of rate over a particular period of time. Exponential decay is the reciprocal of exponential growth when a quantity decreases by the same factor in equal intervals of time, the constant coefficient of the exponential decay function is less than 1. This can be expressed as (1 - r) and is called the decay factor.
According to the definition of the decay factor, its say that when the value of x increases then the decay factor of the value of y will decrease.
Hence, the value of x will increase then decay factor will decrease the value of y.

Number 15. Find MN please! I do give brainliest!
Answer:
MN = 5
Step-by-step explanation:
From inspection of the given diagram:
[tex]\textsf{MN = $2.5x$}[/tex][tex]\textsf{NR = $x$}[/tex][tex]\textsf{MNR = $5x - 3$}[/tex]Therefore:
[tex]\implies \sf MN+NR=MNR[/tex]
[tex]\implies 2.5x+x=5x-3[/tex]
[tex]\implies 3.5x=5x-3[/tex]
Add 3 to both sides:
[tex]\implies 3.5x+3=5x-3+3[/tex]
[tex]\implies 3.5x+3=5x[/tex]
Subtract 3.5x from both sides:
[tex]\implies 3.5x+3-3.5x=5x-3.5x[/tex]
[tex]\implies 3=1.5x[/tex]
[tex]\implies 1.5x=3[/tex]
Divide both sides by 1.5:
[tex]\implies 1.5x \div 1.5=3 \div 1.5[/tex]
[tex]\implies x=2[/tex]
Substitute the found value of x into the expression for MN:
[tex]\implies \textsf{MN}=2.5(2)[/tex]

To rationalize the denominator of 4√4/25, by what number would you multiply the numerator and denominator of the fraction?
Rationalization is multiplying a surd by another similar surd to obtain a rational number. In mathematics, a surd is an expression involving a square, cube, or another kind of root symbol. The surd used for multiplication is called the rationalization factor (RF). Rationalize the denominator to make it easier to perform calculations with rational numbers. Rationalizing a denominator with a fraction removes all root terms, such as square roots and cube roots, from the denominator.
[tex]\frac{4}{\sqrt{\frac{4}{25}}}[/tex]
[tex]\begin{aligned}&\frac{4}{\frac{\sqrt{4}}{\sqrt{25}}}\\&\frac{\frac{4}{\sqrt{2^2}}}{\sqrt{5^2}}\end{aligned}[/tex]

Answer:
x = 0.25
Step-by-step explanation:
[tex]9\sqrt{x} =5-2x[/tex]
[tex]81x = 25 - 20x + 4x^{2}[/tex]
[tex]0=4x^{2} -101x+25[/tex]
[tex]0 = 4x^{2} -1x-100x+25[/tex]
[tex]0=x(4x-1)-25(4x-1)\\0=(x-25)(4x-1)[/tex]
[tex]x=25,\frac{1}{4}[/tex]
[tex]2*25+9\sqrt{25} =5\\50+9*5=5\\50+45=5\\95=5[/tex]
[tex]2*\frac{1}{4}+9\sqrt{\frac{1}{4} } =5 \\0.5+9*\frac{1}{2} =5\\0.5+4.5=5\\5=5[/tex]
Answer:
[tex]x=\dfrac{1}{4}[/tex]
Step-by-step explanation:
Given equation:
[tex]2x+9\sqrt{x}=5[/tex]
Subtract 2x from both sides to isolate the square root:
[tex]\implies 2x+9\sqrt{x}-2x=5-2x[/tex]
[tex]\implies 9\sqrt{x}=5-2x[/tex]
Square both sides to eliminate the square root:
[tex]\implies (9\sqrt{x})^2=(5-2x)^2[/tex]
[tex]\implies 81x=(5-2x)(5-2x)[/tex]
[tex]\implies 81x=25-20x+4x^2[/tex]
Subtract 81x from both sides:
[tex]\implies 81x-81x=25-20x+4x^2-81x[/tex]
[tex]\implies 0=25-101x+4x^2[/tex]
[tex]\implies4x^2-101x+25=0[/tex]
To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to [tex]ac[/tex] and sum to [tex]b[/tex]:
[tex]\implies ac=4 \cdot 25=100[/tex]
[tex]\implies b=-101[/tex]
Therefore, the two numbers are -1 and -100 as:
[tex]\implies -1 \cdot -100=100=a[/tex]
[tex]\implies -1+(-100)=-101 =b[/tex]
Rewrite [tex]b[/tex] as the sum of these two numbers:
[tex]\implies4x^2-x-100x+25=0[/tex]
Factor the first two terms and the last two terms separately:
[tex]\implies x(4x-1)-25(4x-1)=0[/tex]
Factor out the common term (4x - 1):
[tex]\implies (x-25)(4x-1)=0[/tex]
Apply the zero-product property:
[tex](x-25)=0 \implies x=25[/tex]
[tex](4x-1)=0 \implies x=\dfrac{1}{4}[/tex]
Input each solution into the original equation to check its validity:
[tex]\begin{aligned}x=25 \implies 2(25)+9\sqrt{25}&=5\\50+9(5)&=5\\50+45&=5\\95 & \neq 5\end{aligned}[/tex]
Therefore, x = 25 is not a valid solution.
[tex]\begin{aligned}x=\dfrac{1}{4}\implies 2\left(\dfrac{1}{4}\right)+9\sqrt{\dfrac{1}{4}}&=5\\\dfrac{1}{2}+9(\dfrac{1}{2})&=5\\\dfrac{1}{2}+\dfrac{9}{2}&=5\\\dfrac{10}{2}&=5\\5 & = 5\end{aligned}[/tex]
Therefore x = ¹/₄ is a valid solution.
Therefore, the only valid solution to the equation is x = ¹/₄.

The number line shows the distance in meters of two birds, A and B, from a worm located at point X:
Part A: Expression for the distance in meters between given two birds using subtraction = 2.5 - (-2.5)
Part B: The distance between two birds using additive inverse 2.5- (-2.5) =5 meters
What is an expression and additive inverse?An expression is an combination of numbers and mathematical operations such as addition, subtraction, division and multiplication with equating any two terms.
Additive inverse : Additive inverse of an number a is the number that when adds to a gives zero .
Let b be additive inverse of a, then a + b =0
Then, b = -a
Given two birds A and B are at points x= -2.5 and y = 2.5 respectively
Therefore, the expression for the distance in between given two birds
= y - x = 2.5- (-2.5)
We an clearly see that -2.5 is additive inverse of 2.5
Distance between the two birds = 2.5 -(-2.5) =2.5 +2.5 = 5 meters
Therefore, the expression for distance between the two birds A and B is 2.5-(-2.5) and the distance is 5 meters.

The option that describes Myra’s distance as time increases is increasing.
What is the change in Myra's distance?
Looking at the table provided, it can be seen that as time passes, the distance ran by Myra increases. It can be seen that distance increases from 0.4miles to 0.8 miles when time increases from 2 seconds to 4 seconds.
Change in distance run per time = change in distance / change in time
(0.4 - 0) / (2 - 0)
0.4 / 2 = 0.2

What is the equation of a line that passes through the point (2,−2) and is perpendicular to y=x4−3 ?
The equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2
How to find the equation of the perpendicular line?The equation of the line is given as
y = 4x - 3
Rewrite the equation as
y = 4x - 3
A linear equation is represented as
y = mx + c
Where
Slope = m
So, we have
m = 4
The slopes of perpendicular lines are opposite reciprocals
This means that
m2 = -1/m1
So, we have
m = -1/4
Evaluate
m = -1/4
The equation of the perpendicular line is then calculated as
y = m(x - x1) + y1
Where
(x1, y1) = (2, -2)
This gives
y = -1/4(x - 2) - 2
Evaluate
y = -1/3x + 1/2 - 2
Evaluate the sum and the difference
y = -1/3x - 3/2
So, the equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2
Hence, the required equation of a line perpendicular to y = 4x - 3 that passes through the point (2,-2) is y = -1/3x - 3/2
