Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5

Answer:
1/100
Step-by-step explanation:
This is just digits...
57.237 = 50+7+0.2+3*___+0.007
well if you take a closer look
57.237 = 57.207 + 3*___
0.03 = 3*___
So you must have 0.01 for that spot, or if we follow the format of the question, you rewrite it as 1/100
Answer:
0.01 or 1/100

deposited? Round to the nearest cent.
Answer:
Step-by-step explanation:
What grade?
Answer:
$67
Step-by-step explanation:
4000 for 4% equal $160/year total in 5 year equal $4800
the other one 4160 1 year, 4327 2 year, 4500 3 year, 4680 4 year, 4867 5 year the difference is $67 more has Roger than Roxanne

A scientist observed a bacterium in a microscope. It measured about 0.0000029 meter in diameter. Which of the following is closest to 0.0000029?
A.
2×10−6
B.
2×10−5
C.
3×10−5
D.
3×10−6
Answer: A. [tex]2\times10^{-6}[/tex].
Step-by-step explanation:
Given: The diameter of bacterium = 0.0000029 meter
≈ 0.000002 meter [ with 6 decimal places]
[tex]=\dfrac{2}{1000000}=\dfrac{2}{10^6}[/tex]
[tex]=2\times10^{-6}[/tex] meters [[tex]\dfrac{1}{a^n}=a^{-n}[/tex]]
i.e. [tex]2\times10^{-6}[/tex] closest to 0.0000029.
Hence, the correct option is A. [tex]2\times10^{-6}[/tex].

If k‐th term of a sequence is ak = ( -1) ^k(2-k)k/2k-1
,what is its next term ak+1 when k is even?
Given:
kth term of a sequence is
[tex]a_k=\dfrac{(-1)^k(2-k)k}{2k-1}[/tex]
To find:
The next term [tex]a_{k+1}[/tex] when k is even.
Solution:
We have,
[tex]a_k=\dfrac{(-1)^k(2-k)k}{2k-1}[/tex]
Put k=k+1, to get the next term.
[tex]a_{k+1}=\dfrac{(-1)^{k+1}(2-(k+1))(k+1)}{2(k+1)-1}[/tex]
If k is even, then k+1 must be odd and odd power of -1 gives -1.
[tex]a_{k+1}=\dfrac{(-1)(2-k-1)(k+1)}{2k+2-1}[/tex]
[tex]a_{k+1}=\dfrac{(-1)(1-k)(1+k)}{2k+1}[/tex]
[tex]a_{k+1}=-\dfrac{1^2-k^2}{2k+1}[/tex] [tex][\because (a-b)(a+b)=a^2-b^2][/tex]
[tex]a_{k+1}=-\dfrac{1-k^2}{2k+1}[/tex]
Therefore, the next term is [tex]a_{k+1}=-\dfrac{1-k^2}{2k+1}[/tex].

which statement describes the graph of the function f(x)=x^2-1/x^2-2x+1
A. there is a hole at x=-1
B. there is a vertical asymptote at x=-1
C. the y-intercept is y=-1
D. there is a horizontal asymptote at y=-1
Answer:
The Y-intercept is -1
Step-by-step explanation:
M*thway is a pathway to many abilities some considered to be... unnatural
Statement (C) the y-intercept is y=-1 describes the graph of the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = \dfrac{x^2-1}{x^2-2x+1}[/tex]
The above function is a rational function.
The denominator cannot be zero
x² - 2x + 1 ≠ 0
(x - 1)²≠ 1
x ≠ 1
To find y-intercept plug x = 0
f(0) = -1
Thus, statement (C) the y-intercept is y=-1 describes the graph of the function.

You and your friend join a new gym that requires a one-time joining fee and monthly payments. Your friend chooses the 1 year plan and pays $687, while you elect the 18 month contract which costs $981. Use this information to determine the linear model used to calculate cost from months of membership.
Answer:
C = 99 + 49m
x = $99
y = $49
Step-by-step explanation:
Let
x = one time joining fee
y = monthly payment
Your friend:
1 year = 12 months
x + 12y = $687
You:
x + 18y = $981
x + 12y = 687 (1)
x + 18y = 981 (2)
Subtract (1) from (2)
18y - 12y = 981 - 687
6y = 294
Divide both sides by 6
y = 294 /6
= 49
x = $49
Substitute y = 49 into
x + 12y = 687
x + 12(49) = 687
x + 588 = 687
x = 687 - 588
= 99
x = $99
C = 99 + 49m
Where,
C = total charges
m = number of months
99 = a one time joining fee
49 = charges per month
HELP ME!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
The correct option is A
Step-by-step explanation:
Since (1, 3) are the solutions to the function g(x), then
g(x) = (x – 1)(x – 3) = x² –3x – x + 3 = x² – 4x + 3
We know that f(x) is on the same plane and f(1) = 1.
Let's take g(1) = (1 – 1)(1 – 3) = 0
Therefore, when x = 1; f = 1 and g = 0. Hence
g(1) = f(1) – 1
In order words, g(x) could be f(x) – 1.
The correct option is A

2. A baby gained 15 pounds from birth to his first birthday.
Write this amount as an integer.
solve for x
|2x-4|+6=8
Solve for x
|2x -4| + 6 =8
subtract 6 from both sides, then solve
|2x - 4| = 2 and |2x -4| = -2
2x - 4 = 2 2x - 4 = -2
+4 +4 +4 +4
2x = 6 2x = 2
divide by 2 to isolate the variable
x = 3 x = 1
