Answer:
a) 4x+6
b) 28
Step-by-step explanation:
The perimeter is equal to 1+x+1+x+1+1+1+x+1+x.
Simplifying we have 4x+6.
If we plug in 5.5 for x, we get 4*5.5+6=28

match each function with its rate of growth or decay
Answers
Answer:
y=5(1.05)^t=5% rate of growth
f(t)=50(0.95)^t=5% rate of decay
g(t)=50(1.5)^t=50% rate of growth
y=5(.5)^5=50% rate of decay
Step-by-step explanation:
y=5(1.05)^t= 1+x=1.05. x=0.05. 0.05= 5%, 5% rate of growth,
f(t)=50(0.95)^t=1-x=0.95, x=-0.05=-5%=5% rate of decay
g(t)=50(1.5)^t=1+x=1.5, x=0.5=50%, 50% rate of growth
y=5(.5)^5=1+x=0.5, x=-0.5=50%, 50% rate of decay
If this helps please mark as brainliest
The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.
What is an exponent?Consider the function:
y = a (1 ± r)ˣ
Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is a plus sign, then there is exponential growth happening by r fraction or 100r %
If there is a minus sign, then there is exponential decay happening by r fraction or 100r %
The functions are given as,
y = 5 · (1.05)ⁿ
y = 5 · (1 + 0.05)ⁿ
The growth rate is 5%.
y = 50 · (0.95)ⁿ
y = 50 · (1 - 0.05)ⁿ
The decay rate is 5%.
y = 50 · (1.5)ⁿ
y = 50 · (1 + 0.5)ⁿ
The growth rate is 50%.
y = 5 · (0.05)ⁿ
y = 5 · (1 - 0.5)ⁿ
The decay rate is 50%.
The correct matching of the functions y = 5 · (1.05)ⁿ, y = 50 · (0.95)ⁿ, y = 50 · (1.5)ⁿ, and y = 5 · (0.05)ⁿ will be growth rate is 5%, the decay rate is 5%, the growth rate is 50%, and the decay rate is 50%, respectively.

Answer:
Use absolute difference
Step-by-step explanation:
Given
The given parameters can be represented as:
[tex]Expense > Income[/tex]
[tex]Income - Expense< 0[/tex]
Required
Eliminate negative difference
To eliminate negative difference, Sara has to make use of absolute difference when calculating the difference between her income and expense.
Take for instance:
[tex]Income = 10[/tex]
[tex]Expense = 12[/tex]
The difference between both is:
[tex]Income - Expense = 10 - 12[/tex]
[tex]Income - Expense = -2[/tex]
But if she uses absolute difference, the result will be:
[tex]|Income - Expense| = |10 - 12|[/tex]
[tex]|Income - Expense| = |-2|[/tex]
[tex]|Income - Expense| = 2[/tex]

B. A'(-5, -2) C'(-1, 5) and B'(-4, -2) D'(0, 5)
C. A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0)
D. A'(5, 2) C'(1, -5) and B'(4, 2) D'(0, -5)
Answers
Option C : A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0) is correct.
We have two line segments AB and CD parallel to each other.
We have to find the new endpoints if the parallel lines are reflected across the x - axis.
How will you find the image of the point across the x - axis?For a point P(x, y), its reflection across the x-axis is P'(x, -y).
From the figure - the coordinates of points A, B, C, D are -
[tex]A(2,5)\\B(2,4)\\C(-5, 1)\\D(-5, 0)[/tex]
We know the image of the point P(x, y) across the x-axis is P'(x,-y). Therefore, the coordinates of the points, when they are reflected across the x-axis are-
[tex]A(2,5) - > A'(2, -5)\\B(2, 4)- > B'(2, -4)\\C(-5, 1)- > C'(-5, -1)\\D(-5,0)- > D'(-5,0)[/tex]
Hence, Option C : A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0) is correct.
