12^2+b^2=20^2 solve

144+b^2=400

b^2= 256 square it

b= 16

Answer:

b=16

Step-by-step explanation:

Answer:

term 1 - term 2 = sequence

so

-17-(-15) = -2

and if you minus the rest by -2 it will give you the next term

-15-(-2) = -13

-13-(-2) = -11

Answer:

2

Answer: Each student will pay about $4.78

Step-by-step explanation: You have to add 76.50 and 23.95 and you will get 100.45 then divide by 21 and your product is $4.78. Hope it helped.

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)

x = 34°

Step-by-step explanation:

corresponding angles made by a transversal intersecting parallel lines are congruent.

Answer:

-15

Step-by-step explanation:

they are opposite angles so they are congruent

x+70=55

x=55-70

x=-15

0.9985

Step-by-step explanation:

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)!

= 90 ways

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

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

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

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.

Answer:

n = 14

Step-by-step explanation:

[tex]5^n = 5^{11} * 5^3[/tex]

simplify the right side

[tex]5^n = 5^{14}[/tex]

Then you can easily see that

[tex]n = 14[/tex]

Answer:

n = 14

Step-by-step explanation:

[tex]a^{x}*a^{y}=a^{x+y}\\\\5^{n} = 5^{11}*5^{3}\\\\5^{n} = 5^{11+3}\\\\5^{n}=5^{14}\\\\[/tex]

n = 14

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]

Step-by-step explanation:

Since, line is intersecting y axis at (0, 1).

Therefore, y-intercept of the graph is 1.

Answer:

1

Step-by-step explanation:

the y intercept is 1 because the line crosses the y axis at 1

(fyi the x intercept is -1 because the line crosses the x intercept at -1)

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.
