answer:
128
step-by-step explanation:
1. recognize how we get to each number in the pattern
to get from 2 to 8 we can either add 6 or multiply by 4
2. lets see if either of those match up with the rest of the numbers in the pattern
0.125 + 6 = 6.125
our next value is .5 not 6.125
0.125 × 4 = .5
that works! so lets see if it works with the rest of our pattern -
0.5 × 4 = 2
it works! so our pattern is multiplying each value by 4
3. use our pattern on the value of 8
8 × 4 = 32
32 is our 5th value but we are looking for our 6th value
4. use on pattern on the 5th value (32)
32 × 4 = 128
The 6th number in the pattern is calculated by identifying the rule that each number is being multiplied by 4 to get the next one. By continuously applying this rule, we find that the 6th number is 128.
Explanation:The subject of this question involves the identification and continuation of a numerical pattern. The given pattern is 0.125, 0.5, 2, 8. To recognize this pattern, observe the relationship between consecutive numbers. It seems like each number is being multiplied by 4 to obtain the next one. We can apply the same rule to find the 6th number in the sequence:
Multiply the 4th number (8) by 4 to get the 5th number = 8*4 = 32. Multiply the 5th number (32) by 4 to get the 6th number = 32*4 = 128.Therefore, the 6th number in the given pattern should be 128.

a mattress store charges 7% sales tax and a $50 delivery fee. The delivery fee is not subject to sales tax. The following functions represent the situation F(a)=1.07a and g (b)= b+50
Solve for g (f (a)).
Answer: [tex]g(f(a))=1.07a+50[/tex]
Step-by-step explanation:
The given functions are: [tex]f(a)=1.07a[/tex] and [tex]g(b)= b+50[/tex]
[tex]g(f(a))[/tex] means [tex]f(a)[/tex] is the input of the function [tex]g[/tex].
Thus, [tex]g(f(a))= g(1.07a)[/tex]
Now replacing [tex]b[/tex] as [tex]1.07a[/tex] into the given function of [tex]g(b)[/tex], we will get......
[tex]g(1.07a)= 1.07a+50[/tex]
So, [tex]g(f(a))=1.07a+50[/tex]

2.Find the triangle bounded by the y-axis the line f(x)=9- 6/7x and the line perpendicular to it that passes through the origin
We need to find the triangle bounded by the y-axis the line [tex]f(x)=9-\frac{6}{7}x[/tex] and the line perpendicular to it that passes through the origin.
This triangle is illustrated in the First Figure bellow. The triangle has been dotted with black dots. So, let's identify each part of this graph:
Therefore, this line is the blue one and is written as:
[tex]f(x)=\frac{7}{6}x[/tex]
To find [tex]y(t)[/tex] we need to find the slope and y-intercept. So, taking two points:
[tex]P_{1}(15,150) \ and \ P_{2}(25,450) \\ \\m=\frac{450-150}{25-15}=30[/tex]
So:
[tex]Using \ P_{1}(15,150) \\\\y=30t+b\\\\150=30(15)+b \therefore b=-300 \\\\\boxed{y(t)=30t-300}[/tex]
The y-intercept is [tex]b=-300[/tex] and has been calculated above. This value represents the profit in thousands of dollars in 1980, that is, there is no any profit or there is a lost of $300.000.
The x-intercept can be found when y=0 (year 1980), that is:
[tex]y(t)=30t-300 \\\\0=30t-300 \therefore t=10[/tex]
This value shows that there is no any profit for the company at the year that represents t=10 (year 1990), because at this point the company starts earning money.
The slope of this function is [tex]m=30[/tex]
This value tells you that the profit increases $30.000 each year.

Two large topping pizzas cost $25.00. what is the constant of proportionality (k)?
Solve the equation. -3x + 1 + 10x = x + 4
Answer:
[tex]x=[tex]\frac{1}{2}[/tex][/tex]
Step-by-step explanation:
Solving the equation mean finding the value of x
Equation given is:
[tex]-3x+1+10x=x+4[/tex]
Now what we need to do is take the values with x in it to the left side of the equation and the other numbers to the right side of the equation.
[tex]-3x+10x-x=4-1[/tex]
Now simplify values with x and the numbers.
[tex]6x=3[/tex]
[tex]x=[tex]\frac{1}{2}[/tex][/tex]
Therefore [tex]x=[tex]\frac{1}{2}[/tex][/tex]
x = [tex]\frac{1}{2}[/tex]
simplify the left side by collecting like terms
7x + 1 = x + 4 ( subtract x from both sides )
6x + 1 = 4 ( subtract 1 from both sides )
6x = 3 ( divide both sides by 6 )
x = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

What is the solution of sqrt1-3x=x+3
x = - 1
given [tex]\sqrt{(1-3x)}[/tex] = x + 3
square both sides
1 - 3x = (x + 3 )² ( expand right side using FOIL )
1 - 3x = x² + 6x + 9 ( subtract 1 - 3x from both sides )
0 = x² + 9x + 8
0 = ( x + 1)(x + 8)
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = -1
x + 8 = 0 ⇒ x = - 8
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = - 1 : [tex]\sqrt{1+3 }[/tex] = 2 and - 1 + 3 = 2 ← true
x = - 8 : [tex]\sqrt{1+24}[/tex] = 5 and - 8 + 3 = -5 ← false
thus the only solution is x = - 1
Explain why P(A|D) and P(D|A) from the table below are not equal.
Answer:
Step-by-step explanation:
Recall the definition for conditional probability.
We have P(A/D) = P(A and D)/P(D)
P(AD) = 2/17
P(A) = 8/17 and P(D) = 10/17
From the definition of conditional probability,
P(A/D) = P(AD)/P(D) = 2/17 divided by 10/17 = 1/5
But P(D/A) = P(AD)/P(A) = 2/17 divided by 8/17 = 1/4
Hence the two are not equal.
This is because there is a difference in the denominators
P(A|D) and P(D|A) from the table are not equal because the total number of A and D are not equal
From the table, we have the following parameters:
n(A) = 8n(D) = 10n(A and D) = 2P(A|D) and P(D|A) are both conditional probabilities, and they are calculated using:
[tex]P(A|D) = \frac{n(A\ and\ D)}{n(D)}[/tex]
[tex]P(D|A) = \frac{n(A\ and\ D)}{n(A)}[/tex]
So, we have:
[tex]P(A|D) = \frac{2}{10}[/tex]
[tex]P(A|D) = 0.2[/tex]
[tex]P(D|A) = \frac{2}{8}[/tex]
[tex]P(D|A) = 0.25[/tex]
From the above computations, we have:
[tex]P(D|A) \ne P(A|D)[/tex]
This is so, because:
The total number of A and D are not equal

Three is a zero of the equation x^3−4x^2−3x+18=0.
Which factored form is equivalent to the equation?
A (x+2)(x−3)^2=0
B (x−2)(x−3)^2=0
C (x+2)(x−√3)(x+√3)=0
D (x−2)(x−3)(x+3)=0
x^3−4x^2−3x+18=0
(x - 3)^2 (x + 2) = 0
Choice B
A
since x = 3 is a zero then (x - 3) is a factor
dividing x³ - 4x² - 3x + 18 by (x - 3) gives
x³ - 4x² - 3x + 18 = (x - 3)(x² - x - 6 ) = 0,
(x - 3)(x - 3 )(x + 2 ) = 0
(x + 2 )(x - 3)² = 0 → A

* For division, the result may be a polynomial. In the specific example given here for B, it is not.
The term closure in mathematics refers to the property of a set, in this case, polynomials, where doing certain operations (addition, subtraction, multiplication) with any numbers from the set always yields a number within the set. The options demonstrating closure in a polynomial are A, C, D, E, all but option B, which implies division.
Explanation:The term 'closure' in mathematics refers to the property of a set under an operation where the operation performed on any numbers in the set always produces a number that is also in that set. In the case of polynomials, the operations could be addition, subtraction, or multiplication.
The expressions that demonstrate closure in a polynomial for addition, subtraction, and multiplication are all but option B. Option B, '(x^2+2) over (X -1)', isn't representative of closure in a polynomial as it implies a division operation. Polynomial closure doesn't include division because it can produce numbers outside the original set.
So, the correct answers are A.(x^2+2) (x-1), C.(x+1) plus (X^2-3X -2), D.(X +5)-(3X +6) and E.4/8x as they illustrate closure by either multiplication of two polynomials, addition of two polynomials, or subtraction of two polynomials.

Jared has taken out a loan for his car. His monthly payments amount to $650. If his loan is for 36 months, and he paid a down payment of $400, what is the total cost of the car for Jared? A. $15,050 B. $23,800 C. $28,300
B! 650 x 36 +400 = 23,800!
Answer:
$23800.
Step-by-step explanation:
Monthly payment of loan of a car = $650
His loan is for 36 months
So, Total payment of 36 months = [tex]36 \times 650[/tex]
= [tex]23400[/tex]
He paid the down payment of amount $400
So, Total cost of the car = [tex]23400+400[/tex]
= [tex]23800[/tex]
Hence the total cost of the car for Jared is $23800.
So, Option B is correct.

Parallel lines have equal slopes, thus
y = - 2x + c is the partial equation.
