rewrite the function g(x)=2x^2+16x+6 in vertex form by completing the square
The vertex form of the function g(x)= 2[tex]x^2[/tex]+16x+6 is g(x)= 2[tex](x+4)^2[/tex]-26.
What is vertex form of the function?
The function's maximum or lowest possible output is represented by the vertex of the quadratic function's graph. When viewing a graph, the vertex is the highest or lowest point on the parabola. Utilizing the vertex formula is the simplest technique to discover the vertex. It is simple to locate the vertex of the parabola using the vertex form of a quadratic equation. Y=a(xh)2+k is the definition of the generic vertex form, where h is the x-coordinate and k is the y-coordinate of the vertex.
Here the given function is ,
=> g(x) = 2[tex]x^2[/tex]+16x+6
=> g(x) = 2([tex]x^2+[/tex]8x+3)
=> g(x) = 2([tex]x^2+[/tex]8x+16-16+3)
=>g(x) = 2 [[tex](x+4)^2[/tex]-13]
=> g(x)= 2[tex](x+4)^2[/tex]-26
Therefore vertex form of the function is g(x)= 2[tex](x+4)^2[/tex]-26 and vertex is (-4,-26).

Find the equation of the straight line passing through the point (3, 5)
which is perpendicular to the line
y = 3x + 2
Answer:
y = -1/3x +6
Step-by-step explanation:
You want the equation of the line through (3, 5) perpendicular to the line y = 3x +2.
Perpendicular lineThe given equation is in slope-intercept form. This lets us identify its slope as 3.
y = mx + b . . . . . . line with slope m and y-intercept b
y = 3x +2 . . . . . . . line with slope 3 and y-intercept 2
The perpendicular line will have a slope that is the opposite reciprocal of this:
m = -1/3 . . . . slope of the perpendicular line
Point-slope formThe equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The equation for a line with slope -1/3 through point (3, 5) is ...
y -5 = -1/3(x -3)
Slope-intercept formSolving for y gives us ...
y = -1/3x +1 +5 . . . . . eliminate parentheses, add 5
y = -1/3x +6 . . . . . equation of the desired line

Explain sequences and seriesFor the arithmetic, geometric, and harmonic sequences, a collection of sequences and series formulas is provided below. The sequence and series formulas presented here contain formulas for determining the sum of the n terms in a series as well as the nth term of the sequence.
A common difference exists between two succeeding terms in an arithmetic series. There is a typical ratio between succeeding terms in a geometric series.
1. Given sequence is 27, 9, 3, ...
As the difference between the number is large.
So, we will check for geometric sequence.
[tex]r = \frac{27}{9} = \frac{3}{3} = \frac{1}{3}[/tex]
Therefore, the sequence is geometric.
2. Given sequence is 4, 8, 12, ...
As we can see there is uniform difference of 4
Therefore, the sequence is arithmetic.
3. Given sequence is 50, 56, 60, ...
As the difference between the number is not uniform.
So, we will check for geometric sequence.
[tex]r = \frac{50}{56} \neq \frac{56}{60}[/tex]
There, the sequence is neither arithmetic nor geometric.
4. Given sequence is 36, 12, 4, ...
As the difference between the number is large.
So, we will check for geometric sequence.
[tex]r = \frac{36}{12} = \frac{12}{4} = 3[/tex]
Therefore, the sequence is geometric.
5. Given sequence is 4, 24, ...
The number of terms is very less and hence we can't decide.

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Brown rice: $2.00 per pound
Quinoa: $4.50 per pound
let the brown rice sold x ounces
and, let the Quinoa sold be y ounces
So, the equations are:
x + y= 17
2x+ 4.5y= 54
2( 17- y) + 4.5y= 54
34 - 2y + 4.5y= 54

Suzanne's average daily balance for last month was x dollars. The finance
charge was y dollars.
a. What was the monthly percentage rate?
b. What was the APR?
Part a: Monthly percent rate = y/x
Part b: APR = y/x × 12.
What is meant by the term APR?The annual interest produced by a sum that is paid to investors or charged to borrowers is referred to as the annual percentage rate (APR). APR is a percentage that expresses the actual annual cost of borrowing money over the course of a loan or the income from an investment. An APR might not accurately represent the cost of borrowing but since lenders have some latitude in determining it, excluding some fees.APR and APY (annual percentage yield), a computation that takes interest compounding into account, should not be confused.For the given question;
Average daily balance sheet of Suzanne's is x dollars.
Finance charges = y
Part a: monthly percentage rate
Finance charge = Monthly percent rate × Average daily balance
Monthly percent rate = Finance charge/Average daily balance
Monthly percent rate = y/x
Part b: APR
The annual percentage rate (APR) is calculated by dividing the periodic interest rate even by number of periods in the year that it was in effect. The number of times the rate is applied to a balance is not stated.Thus,

The largest U.S. flag in the world is 225 feet by 505 feet.
------------------------
If a square yard of the flag weighs about 3.8 ounces, how much does the entire flag weigh in pounds?
The weight of the U.S. flag in pounds is 2,998.44 pounds.
What is the weight of the flag?The dimension of the U.S. flag is in feet. The dimensions have to be converted to yards.
1 foot = 1/3 yards
225 / 3 = 75 yards
505 / 3= 168.33 yards
The next step is to determine the area of the U.S. flag.
Area = length x width
75 x 168.33 = 12,625 yards²
Weight of the U.S. flag in ounces = 12,625 yards² x 3.8 = 47,975 ounces
1 ounce = 1/16 pounds
Weight of the U.S. flag in pounds = 47,975 / 16 = 2,998.44 pounds

The computation of each of the adult ticket cost is as follows:
Let x be the cost of each adult ticket.
Then, cost of 3 adult tickets = 3x.
Now:
The cost of 1 student ticket = $7
The cost of 4 student ticket = $7(4)
Then, we get the following equation:

decide whether inductive reasoning or deductive reasoning is used to reach the conclusion: "what goes up must come down. the ball went up. it will come down."
The statement ""what goes up must come down. the ball went up. it will come down." can be reached through a deductive reasoning.
What is a deductive reasoning?The mental process of forming deductive deductions is known as deductive reasoning. An inference is deductively valid if its conclusion follows logically from its premises, i.e. if the premises cannot be true while the conclusion is false.
The primary distinction between inductive and deductive thinking is that inductive reasoning seeks to develop a hypothesis, whereas deductive reasoning seeks to test an existing theory. Inductive thinking proceeds from individual observations to broad generalizations, whereas deductive reasoning proceeds in the other direction.
In conclusion, the correct option based on the information is a deductive reasoning.

a school has 400 grade 9's, 375 grade 10's, 300 grade 11's and 325 grade 12's. twenty students from each grade are surveyed
The type of bias that can be present in stratified sampling is that the students cannot be selected to accurately reflect the population.
How are samples classified?Samples may be classified according to the five options as follows:
A convenient sample is drawn from a conveniently available pool of options.A random sample is equivalent to placing all options into a hat and taking some of them.In a systematic sample, every kth element of the sample is taken.Cluster sampling divides population into groups, called clusters, and each element of the group is surveyed.Stratified sampling also divides the population into groups. However, an equal proportion of each group is surveyed.In this problem, an equal amount of students from each class was surveyed, hence a stratified sample was used.
The type of bias present in stratified sampling is that the students cannot be selected to accurately reflect the population.
