Answer: C. 170.3 cm squared
Answer:
170.3cm^2
Step-by-step explanation:
The total surface area is the sum of surfaces of all sides.
We have 2 sides of 7.9cmx4.5cm, 2 sides of 7.9cmx4cm, and 2 sides of 4.5cm*4cm.
7.9cm*4.5cm = 35.55cm^2
7.9cm*4cm = 31.6cm^2
4.5cm*4cm = 18cm^2
2 * (35.55cm^2 + 31.6cm^2 + 18cm^2) = 2 * 85.15cm^2 = 170.3cm^2

2x - 8 = 12 - 4x
solve for variable
Answers
Answer:
x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]
Step-by-step explanation:
2x - 8 = 12 - 4x
1) Add 8 on boths sides:
2x - 8 + 8 = 12 - 4x + 8
2x = 20 - 4x
2) Add 4x to both sides:
2x + 4x = 20 - 4x + 4x
6x = 20
3) Divide 6 on both sides
[tex]\frac{6x}{6} = \frac{20}{6}[/tex]
x = [tex]\frac{10}{3}[/tex] or [tex]3\frac{1}{10}[/tex]

What is the importance of polynomial functions and how this real life applications improve or contribute to the value of life
Answers
Answer:
What is the importance of polynomial functions?
Polynomials are an important part of the "language" of mathematics and algebra. They are used in nearly every field of mathematics to express numbers as a result of mathematical operations. Polynomials are also "building blocks" in other types of mathematical expressions, such as rational expressions.
How these real-life applications improve or contribute to the value of life?
Since polynomials are used to describe curves of various types, people use them in the real world to graph curves. Combinations of polynomial functions are sometimes used in economics to do cost analyses, for example. Engineers use polynomials to graph the curves of roller coasters and bridges.

I learned a trick on and you have to look at the numbers and see what’s repeated the most, so 90 is repeated a lot and it’s at the front, 180 and 45 are repeated too, but since 90 is at the front then the back number should be 45, so it’s B, it’s actually quite accurate
5/9 = ?/54 whats the answer
Answers
Answer:
30/54
Step-by-step explanation:
1st make and equation so 5/9=x/54
now cross-multiply.
5/9=x/54
(5)*(54)=x*(9)
270=9x
you can flip the equation.
9x=270 (next divide both sides by 9)
x=30
so 30/54=5/9

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?
Answers
Answer:
90
Step-by-step explanation:
A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?
This is calculated using the Permutation formula
nPr = n!/(n - r)!
Where:
n = 10 people
r = 2 = 2 positions to be filled , Chairman and Vice chairman
Hence:
10P2 = 10!/(10 - 2)!

What is an equation of the line that passes through the points (5, 5) and (5, -8)
Answers
Answer:
Write the problem as a mathematical expression. (5,5), (5,−8)
Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y=mx+b format.
Slope is equal to the change in y over the change in x , or rise over run.
m=(change in y)/(change in x)
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
m=(y2−y1) / (x2−x1)
Substitute in the values of x and y
into the equation to find the slope.
m=(−8−(5)) / (5−(5))
Finding the slope m.
Undefined
x=5
Step-by-step explanation:
Answer:
m = undefined

Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Coordinates (x, y)Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]Step-by-step explanation:
Step 1: Define
Point (5, 5)
Point (5, -8)
Step 2: Identify
(5, 5) → x₁ = 5, y₁ = 5
(5, -8) → x₂ = 5, y₂ = -8
Step 3: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute in points [Slope Formula]: [tex]\displaystyle m=\frac{-8-5}{5-5}[/tex][Slope] Subtract: [tex]\displaystyle m=\frac{-13}{0}[/tex]Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.

Step-by-step explanation:
The dollar value v (t) of a certain car model that is t years old is given by the following exponential function.
V (t) = 26,000 (0.84)^t
Find initial value of the car and the value after 11 years. Run your answers to the nearest dollar is necessary.
Initial value: $26,000
Value after 11 years: $_____
Answers
Answer:
$ 3820
Step-by-step explanation:
When the car is new, it is 0 year old. It means, t = 0
Initial value = 26,000 (0.84)^0 = 26,000(1)
Initial value = $ 26000
Similarly, when car is 11 year old, t = 11
=> 26000(0.84)¹¹ = 26000(0.14691)
≈ $ 3819.842
≈ $ 3820 (round to near ten)
