The solution to the exponential functions are
a) The function f ( x ) = 300 ( 0.87 )ˣ
b) The function g ( x ) = 100 ( 1.13 )ˣ
c) The value of x = 6
What is exponential growth factor?The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the function be represented as f ( x ) and g ( x )
So , the function f ( x ) is decreasing at a rate of 13 %
Substituting the values in the equation , we get
f ( x ) = 300 ( 1 - 0.13 )ˣ
On simplifying the equation , we get
f ( x ) = 300 ( 0.87 )ˣ
And , the function g ( x ) is increasing at a rate of 13 %
Substituting the values in the equation , we get
g ( x ) = 100 ( 1 + 0.13 )ˣ
On simplifying the equation , we get
g ( x ) = 100 ( 1.13 )ˣ
And , the approximate value when f ( x ) = g ( x ) is
300 ( 0.87 )ˣ = 100 ( 1.13 )ˣ
On further simplification , we get
3 ( 0.87 )ˣ = ( 1.13 )ˣ
Taking logarithm on both sides of the equation , we get
ln ( 5 ) + x ln ( 0.87 ) = x ln ( 1.13 )
And , x [ ln ( 1.13 ) - ln ( 0.87 ) ] = ln ( 5 )
On further simplification , we get
x = ln ( 5 ) / [ ln ( 1.13 ) - ln ( 0.87 ) ]
x = 6.15
x = 6
Hence , the exponential equations are solved

What is the equation of the line that passes through the point (-7,-4) and has an undefined slope?
Answer:
When the slope is UNDEFINED, that means the denominator of the slope formula is ZERO .
Slope formula = (y2 - y1)/(x2 - x1), and the graph is a VERTICAL line and the equation of the line is x =7 . Point (7, -4) is a point on the line.

Hi there! Your answer is all real numbers.
Please see an explanation for a clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
[tex] \large \boxed{ \sf{domain = set \: \: of \: \: all \: \: x - values}}[/tex]
Remember, domain is set of all x-values. Therefore, we can cancel b choice because y>0 is range, not domain.
Given the exponential function
[tex] \large{y = {a}^{x} } \: \: \large({x \in \R}) \: \: \large({y \in \R^{ + } })[/tex]
This is the define of Exponential Function where x is all real numbers and y is all real positive number.
Hence, the define of exponential function proves that x must be all set of real numbers.
How do I find the center and angle of rotation
9514 1404 393
Answer:
B → XC → YD → Z180° rotation about the originStep-by-step explanation:
In general, if PQ is rotated to P'Q', the center of rotation (O) will be the point of intersection of the perpendicular bisectors of PP' and QQ'. The angle of rotation will be the angle POP', or QOQ'.

The correspondence between preimage vertices ABCD and image vertices can be found by naming the vertices in the same order (clockwise) from one whose correspondence you know.
Here, the correspondence between A and W is given. Vertices clockwise from W are WXYZ, so those are the image points corresponding to ABCD.
__
We note that the midpoints of AW and BX are coincident at the origin. That is, the perpendicular bisectors of these segments are coincident at the origin, so the origin (point O) is the center of rotation. The rotation angle is AOW, an angle that measures 180°.
__
The image point coordinates are the opposites of the preimage point coordinates.
A(2, 2) ⇒ W(-2, -2)
B(2, 5) ⇒ X(-2, -5)
C(5, 5) ⇒ Y(-5, -5)
D(5, 2) ⇒ Z(-5, -2)
This is another indication that the rotation is 180° about the origin, since that rotation results in the mapping ...

Complete question:
Cody's school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 7 senior citizen tickets and 14 student tickets for a total of 196 The school took in $104 on the second day by selling 5 senior citizen tickets and 6 student tickets What is the price each of one senior citizen ticket and one student ticket?
Answer :
Señior tickets = $10
Student ticket = $9
Step-by-step explanation:
Let :
Senior ticket = x
Student ticket = y
7x + 14y = 196 - - - (1)
5x + 6y = 104 - - - (2)
Multiply (1) by 5 and (2) by 7
35x + 70y = 980 - - - (3)
35x + 42y = 728 - - - (4)
Subtract (3) and (4)
28y = 252
y = 252 / 28
y = 9
From (1)
7x + 14(9) = 196
7x + 126 = 196
7x = 70
x = 10
Hence,
Señior tickets = $10
Student ticket = $9

A rectangle is dilated by a scale factor of y to create a new rectangle. The area of the new rectangle is y2 times the area of the original rectangle.
True or false ?
Please help
Answer: True
Step-by-step explanation:
Suppose the length and width of the original rectangle is L and W
After dilation by a factor of y, it becomes yL and yW
Area of the original rectangle [tex]A_1=L\times W[/tex]
The area of the dilated rectangle is [tex]A_2=yL\times yW=y^2LW[/tex]
we can see that
[tex]\Rightarrow A_2=y^2A_1[/tex]

Answer:
2 pounds
Step-by-step explanation:
pounds of white candy: 8.25 - (2.5 + 3.75) = 8.25 - 6.25 = 2
The weight of the white candy in pounds will be 2 lb.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Zachary bought 8.25 pounds of red, white, and blue candies for his Fourth of July party. If 2.5 pounds of the candies are red, and 3.75 pounds are blue.
The weight of the white candy will be calculated as,
Pounds of white candy = 8.25 - (2.5 + 3.75)
