The required, option D correctly identifies that the domain values are at regular intervals and the range values have a common factor, which is consistent with an exponential function.
What is an exponential function?The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
To determine whether the data shows an exponential function, we need to check whether there is a constant ratio between successive y-values for a constant change in the x-value.
Looking at the table, we can see that:
When x increases by 3 units (from 3 to 6), y doubles (from 1 to 2).
When x increases by another 3 units (from 6 to 9), y doubles again (from 2 to 4).
When x increases by another 3 units (from 9 to 12), y doubles once more (from 4 to 8).
Therefore, there is a constant ratio of 2 between successive y-values for a constant change in the x-value of 3. This means that the data does show an exponential function.

In all, she practiced for 45 minutes. Let t be the number of minutes that Camila practiced her tap routine. Write and solve an equation to find t.
Answer:
t = 28 minutes
Step-by-step explanation:
Last Saturday, Camila practiced her dance routines for her upcoming competition. She spent some time practicing her tap routine, and then she spent 17 minutes practicing her hip-hop routine. In all, she practiced for 45 minutes. Let t be the number of minutes that Camila practiced her tap routine. Write and solve an equation to find t.
45 minutes = Number of minutes for hip-hop routine + Number of minutes for tap dance
The equation is given as
45 = 17 + t
Solving for t
t = 45 - 17
t = 28 minutes

Find the trigonometric ratio as a fraction Tan N =
Find the trigonometric ratio as a fraction Tan L =
Answer:
Tan N = 4 / 3
Tan L = 3 / 4
Step-by-step explanation:
By Pythagoras theorem,
(LN)² = (MN)² + (LM)²
10² = 6² + (LM)²
100 = 36 + (LM)²
(LM)² = 100 - 36
(LM)² = 64
LM = 8
Tan N
= Opposite / Adjacent
= LM / MN
= 8 / 6
= 4 / 3
Tan L
= 1 / Tan N

Answer:

Step-by-step explanation:
Given f(x) = 3x^3 -5x + k, and x-2 is a factor of f(x), then what is the value of k?
This is an interesting question, since I have to think I have ever seen a question like this asked before.
3x³ - 5x + k i'll try dividing by x-2 and adjust k so there is no remainder
3x² + 6x + 7
x-2 | 3x³ + 0x² - 5x + k
3x³ - 6x
6x² - 5x
6x² - 12x
7x + k
7x - 14
0 remainder is 0 if k = - 14

Complete the tables to determine if the expressions are equivalent. If the expressions are equivalent, name the properties that make them equivalent.
Answer:
For both charts:
Top boxes: -12
Middle Boxes: -9
Bottom Boxes: -6
The equation is given by A = 3 ( x - 5 ) and B = 3x - 15 and they are equivalent
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be represented as A
Now , the value of A is
A = 3 ( x - 5 ) be equation (1)
Now , let the second equation be represented as B
Now , the value of B is
B = 3x - 15 be equation (2)
Now , on simplifying the equation (1) , we get
Substituting the value of x = 1 , 2 , 3 in equation (1) , we get
when x = 1
A = 3 ( 1 - 5 )
A = 3 ( -4 ) = -12
when x = 2
A = 3 ( 2 - 5 )
A = 3 ( -3 ) = -9
when x = 3
A = 3 ( 3 - 5 )
A = 3 ( -2 ) = -6
Now , on simplifying the equation (1) , we get
Substituting the value of x = 1 , 2 , 3 in equation (1) , we get
when x = 1
A = 3 ( 1 ) - 15
A = 3 - 15 = -12
when x = 2
A = 3 ( 2 ) - 15
A = 6 - 15 = -9
when x = 3
A = 3 ( 3 ) - 15
A = 9 - 15 = -6
So , the values of the expressions are the same
Now , applying the distributive property on equation (1) , we get
A = 3 ( x - 5 )
A = 3x - 3 ( 5 )
A = 3x - 15 = B
Hence , the equations are equivalent

c) What is the vertex form of the parabola from Daredevil Danny’s practice jump? (5 points)
f(x)=-12/25(x-25)^2+32
The equation of Daredevil Danny's jump in vertex form is y = -0.32(x - 25)^2 + 32
The key aspects of the graphThe graph that completes the question is added as an attachment
These are the vertex and the intercepts of the graph.
The intercepts tell us about when the time of flight and the time of landing, while the vertex tell about the maximum height of Danny's jump.
From the graph, we have:
Vertex = (25,32)x-intercepts = 15 and 35The value of the coefficient aA quadratic function is represented as:
y = a(x - h)^2 + k
Where:
vertex = (h,k)
So, we have:
y = a(x - 25)^2 + 32
Substitute the value of the x-intercept
0 = a(15 - 25)^2 + 32
Subtract 32 from both sides
a(15 - 25)^2 = -32
Solve for a
a = -0.32
Hence, the value of the coefficient a is -0.32
So, the equation in vertex form is y = -0.32(x - 25)^2 + 32

Which graph represents a reflection of f(x) = 2(0.4)x across the y-axis? On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5). On a coordinate plane, an exponential function decreases from quadrant 3 to quadrant 4 and approaches y = 0 in quadrant 3. It crosses the y-axis at (0, negative 2) and goes through (1, negative 5). On a coordinate plane, an exponential function decreases from quadrant 2 to quadrant 1 and approaches y = 0 in the first quadrant. It goes through the y-axis at (0, 2) and goes through (negative 1, 5). On a coordinate plane, an exponential function increases from quadrant 3 to quadrant 4 and approaches y = 0. It goes through (negative 1, negative 5) and crosses the y-axis at (0, negative 2).
The graph of g(x) is (a) an exponential function approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 2) and goes through (1, 5).
The function f(x) is given as:
[tex]f(x) = 2(0.4)^x[/tex]
The rule of reflection over the y-axis is:[tex](x,y) \to (-x,y)[/tex]
This means that:
[tex]g(x) =f(-x)[/tex]
Substitute -x for x in f(x)[tex]f(-x) = 2(0.4)^{-x}[/tex]
Substitute the expression for f(-x) in the above equation [tex]g(x) =f(-x)[/tex][tex]g(x) = 2(0.4)^{-x}[/tex]
