Hence, the equation of exponential function is represented by y = A(Bˣ)
An exponential function is a mathematical function of the form f(x) = ax, where "x" is a variable and "a" is a constant called the base of the function and it must be greater than 0. The most commonly used exponential basis is the transcendental number e, which is approximately equal to 2.71828The equation in exponential form
y = A(Bˣ)
Case 1 :
x =0 y = 0.02
0.02 = A (B⁰)
A = 0.02
Case 2:
x = 1 y =0.04
0.04 = 0.02(B)
0.04 /0.02 = B
B = 2
Case 3 :
x = 2 y =0.08
0.08 = 0.02(2²)
0.08 = 0.08
Case 4 :
x = 3 y = 0.16
0.16 = 0.02(2³)
0.16 = 0.16
So, we have implemented the eqaution y = A(Bˣ)
We found the values of A & B, and also proved them in case 3 and case 4.
Hence, the equation of exponential function is represented by y = A(Bˣ)

if alpha and beta are the roots of the equation 4 x square - 5 x - 1 equals to 0 find the quadratic equation whose roots are two minus alpha coma to minus beta
Answer:
4x² -11x +5 = 0
Step-by-step explanation:
Given α and β are roots of 4x² -5x -1 = 0, you want to find the quadratic equation that has (2-α) and (2-β) as its roots.
Factored formFactoring out the leading coefficient, we can write the factored form of the given quadratic as ...
4(x -α)(x -β) = 0 = 4x² -5x -1
When the roots are changed from α and β to (2-α) and (2-β), the factored form of the new equation is ...
4(x -(2 -α))(x -(2 -β)) = 0
4(x -2 +α)(x -2 +β) = 0
Negating both factors allows us to write this in a familiar form:
4((2 -x) -α)((2 -x) -β) = 0
Comparing to the original factored quadratic, we see that this is the original with x replaced by (2 -x). Then the quadratic we seek is ...
4(2-x)² -5(2 -x) -1 = 0 . . . . . . . . . . . original with x replaced by (2-x)
4(4 -4x +x²) -10 +5x -1 = 0 . . . . simplify a bit
4x² -11x +5 = 0 . . . . . . . . . . simplify
The quadratic whose roots are (2-α) and (2-β) is 4x² -11x +5 = 0.

Use the given endpoint R and the midpoint M of segment RS to find the
coordinates of the other endpoint S. (Hint: Use the midpoint formula to
find the other endpoint.)
R(7,-17) and M (-2, 3)
Answer:
RS (-11,23)
Step-by-step explanation:
Don't know if this will help but if your looking for an endpoint, I did -2 = x+7/2 To find X. I got -2 from the X coordinate with midpoint. To get rid of the fraction I multiplied by 2 which leads to -4=x+7 since it cancels out the denominator/bottom fraction. X should be -11. Same thing with Y coordinate. 3= y- 17/2. Should give you 6=y- 17 which then becomes Y=23.

What is the difference of ‒6 ‒ 15?
Answer: -21
Step-by-step explanation:
To solve this, you must subtract either one of the numbers from the other, then take the absolute value.
The easiest way is to subtract -6 from 15, since it will allow you to work with positive numbers.
So you do 15 - (-6), which is the same as 15 + 6. The answer is -21, and since it is a positive number, no further calculations are required to find the absolute value.

graph the equation y= 2/3x+5
the equation formula y=2/3x+5 is (3,-3).
In mathematics, what is an equation?Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
based on the available facts;
You might be wondering how, but we can start with that 5 at the end, which denotes the y-intercept.
If 0 is used in place of x, then y=2/30+5y=5
We shall receive the first coordinate as a result, which is (0,5).
Let's then consider the slope, which is 2,3. As you may already be aware, the slope is also known as
rise/run
; what do they mean by that is that the first top number tells you how many units you go up and the second one how many units you go right or how many units you go down and go left.
Now, I know this may seem complicated but let's make it clear. Since we know one coordinate, which is
(0,5)
, from that point by knowing the slope we can find a second point; this point is 2 points above and 3 to the right, which tells us that −5+2
points above gives us −3 and 3 points on the right gives us a new coordinate:
(3,−3)
And since we now know two coordinates, that is enough to draw the line and have the graph.

1/3 of these people got on the coach.

A soup recipe requires 6 ounces of bouillon plus 2 ounces for each quart of water used.
This relationship is represented by the equation b = 2q +6, where b represents the
number of ounces of bouillon and q represents the number of quarts of water
Answer:
Slope=1.000/2.000=0.500
b-i
q-i
b-(2*q+6)=0
Step-by-step explanation:
1.1 Solve b-2q-6 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line b-2q-6 = 0 and calculate its properties
Notice that when b = 0 the value of q is 3/-1 so this line "cuts" the q axis at q=-3.00000
q-intercept = 6/-2 = 3/-1 = -3.00000
When q = 0 the value of b is 6/1 Our line therefore "cuts" the b axis at b= 6.00000
b-intercept = 6/1 = 6.00000
Slope is defined as the change in q divided by the change in b. We note that for b=0, the value of q is -3.000 and for b=2.000, the value of q is -2.000. So, for a change of 2.000 in b (The change in b is sometimes referred to as "RUN") we get a change of -2.000 - (-3.000) = 1.000 in q. (The change in q is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 1.000/2.000 = 0.500
Slope = 1.000/2.000 = 0.500
b-intercept = 6/1 = 6.00000
q-intercept = 6/-2 = 3/-1 = -3.00000

eli wants to combine 0.5 gallons of a 10% acetic acid solution with a 35% solution to make a 15% acetic solution. he needs to determine how many gallons of 35% solution are needed.
0.125 gallons of 35% solution are required to achieve the specified ratio.
This is further explained below.
How many gallons of 35% solution is needed by Eli ?Generally, It takes 0.125 gallons of a 35% solution to get the ratio you want.
Eli wishes to mix 0.5 gallons of a 10% acetic acid solution with a 35% solution to create a 15% acetic acid solution; thus, the calculation below must be done to calculate how many gallons of
5% solutions are required:
1 x 10 + 2 x 35 = 80
=> 80 ÷ 3 = 26.66
1x10 + 1x35 = 45
=>45÷ 2 = 2.5
1 x 10 + 0.5 x 35 = 27.5
=>27.5 ÷ 1.5 = 18.33
1 x 10 + 0.4 x 35 = 24
=>24 ÷ 1.4 = 17.14
1 x 10 + 0.2 x 35 =17
=> 17 / 1.2 = 14.16
1 x 10 + 0.3 x 35 = 20.5
=> 20.5/ 1.3 = 15.76
1 x 10 + 0.25 x 35 = 18.75
=> 18.75 / 1.25 = 15
1 / 2 = 0.5
0.25 / 2 = 0.125

An inequality that represents Alicia’s possible age is x < 8.
For given question,
let x represent Alicia's age.
Amy is eight years older than twice her cousin Alicia’s age.
So, Amy's age would be 2x + 8
The sum of their ages is less than 32.
We write above statement in mathematical expression.
sum of their ages = (2x + 8) + x
= 3x + 8
The sum of their ages is less than 32.
We use the symbol < for 'less than'
So, the mathematical expression form of given statement would be,
(3x + 8) < 32
So, we get an inequality 3x + 8 < 32
⇒ 3x < 32 - 8
⇒ 3x < 24
⇒ x < 24/3
