Step-by-step explanation:
Welcome for the answer. This answer is only for good intentions only report if necessary. Have a great rest of your day!The perimeter of the rectangle is given by the algebraic expression: 4z + 6
How to find the perimeter of a rectangle?The formula for the perimeter of a rectangle is expressed as:
P = 2(L + W)
Where:
W is width
L is length
We are given the following parameters as:
Length = z + 3
Width = z
Thus:
P = 2(z + z + 3)
P = 2(2z + 3)
P = 4z + 6

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

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
= 1 / ( 4 / 3 )

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]
Hence, the graph of g(x) is graph (a)

Find the measure of angle x in the figure below
35°
48°
69°
78°
Answer:
Step-by-step explanation:
So we know that a straight line adds up to 180 degrees.
This means that:
52+59+y = 180
y + 111 = 180
y = 69
We also know a triangle also adds up to 180 degrees.
This means that:
y+x+63 = 180
69+63+x = 180
x + 132 = 180
x = 48
It tells to round to the nearest hundredth and to only use numbers and decimal points. Please help

The roots and vertex, you can find the vertex by using vertex form y=a(x-h)^2+k. You find the roots by solving the quadratic equation.
Step 2: Solve for coefficient a.
a.) What equation is used to find the vertex form of a parabola with the vertex (h, k)? (5 points)
f(x) = a(x-h)^2 +k
b.) Solve for the coefficient a in the vertex form for the parabola in Daredevil Danny’s practice jump using key aspects from step 1. As you solve for the coefficient, explain each step of the process in detail. (15 points)
Not sure about this one...?
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
