Answer:
a. 31/6; 33/6; 35/6
b. + 2/6
c. 37/6; 39/6; 41/6
d. 49/6
Step-by-step explanation:
First we need to find the first three terms.
To do so solve the equations in the boxes.
When dividing by a fraction you multiply by the reciprocal so the equations are now as follows:
2 * 31/12
3 * 11/6
5 * 7/6
Solve these to get
62/12 = 31/6
33/6
35/6
The term to term rule as shown above is adding 2/6 or 1/3.
To find the next three terms in the sequence add 2/6 to the term.
35/6 + 2/6 = 37/6
37/6 + 2/6 = 39/6
39/6 + 2/6 = 41/6.
To find the 10th term you need to write out the arithmetic sequence equation.
an = a1 + (n-1)d
an is the term you want to find and n is the term number in this case that is 10. D is the common difference which in this case is 2/6. Plug these into the equation. A1 is the first term in the equation which in this case is 31/6.
31/6 + (10-1) 2/6
31/6 + (9)2/6
31/6 + 18/6 = 49/6

We have to given that;
The trapezoid I'J'K'L' is a dilation of the trapezoid IJKL.
Here, The length of IJ = 16
And, The length of I'J' = 4
Hence, The scale factor of the dilation is,
⇒ I'J' / IJ = 4 / 16
= 1/4
Thus, The scale factor of the dilation is, 1/4.

Ashley's company makes solid spherical balls out of scrap metal for various industrial uses. A large order just came in to make aluminum balls with a radius of 4.5 in. If Ashley uses 74,325in^3 on average, of aluminum each day making these balls, how many balls does she make, on average, each day?
Answers
Using the formula of volume of a sphere, Ashely's company made 195 balls
Volume of SphereThe volume of sphere is the measure of space that can be occupied by a sphere. If we draw a circle on a sheet of paper, take a circular disc, paste a string along its diameter and rotate it along the string. This gives us the shape of a sphere.
The formula of volume of a sphere is given as
v = 4/3πr³
r = radius = 4.5in
volume of each spherical ball = 4/3π(4.5)³
volume of sphere = 381.7in³
The number of balls she made from 74325 in³ can be found by dividing it by 381.7in³
Number of balls = 194.7≅195 balls

Is the system of equations consistent and independent, consistent and dependent, or inconsistent?
y=−3x+12y=−6x+2
Select the correct answer from the drop-down menu.
consistent and independent
Answers
The system of equation is consistent and independent because it has one unique solution.
How to solve system of equation?If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent.
Therefore, let's solve the equation,
y = -3x + 12
y = -6x + 2
Using substitution,
-6x + 2 = -3x + 12
-6x + 3x = 12 - 2
-3x = 10
x = - 10 / 3
y = -6(-10 / 3) + 2
y = 60 / 3 + 2
y = 20 + 2
y = 2
Therefore, the system of equation is consistent and independent.

A survey was given to a random sample of 80 residents of a town to determine whether they support a new plan to raise taxes in order to increase education spending. Of those surveyed, 52 respondents said they were in favor of the plan. Determine a 95% confidence interval for the proportion of people who favor the tax plan, rounding values to the nearest thousandth.
Answers
With a 95 percent confidence interval, the proportion of people who favor the tax plan is 0.546 ,0.755
How to solve for the intervalThe value of n is the random sample n = 80
we have x as the number of people surveyed, = 52 respondents
Then p = x / n
p = 52 / 80
p = 0.65
From the z critical table, 95% confidence level = 1.96
we would have to use the confidence interval formula. This is given as:
[tex]p +- Z * \sqrt{\frac{p*(1-p)}{n} }[/tex]
we have to put in the values
[tex]0.65 +- 1.96 * \sqrt{\frac{0.65*(1-0.65)}{80} }[/tex]

What are trigonometric ratio?
The ratio of sides of a right angled triangle is known ars trigonometric ratios. There are six trigonometric ratios. Which are as follows:
sin = P/H, cos = B/H, tan = P/B
cosec = H/P, sec = H/B, cot = B/P
Here, P is perpendicular, H is hypotaneous, and B is base. These ratios simplify the calculation.
SInce the angle is not specified hence, consider the given angle is L. Now, L is given angle hence, the base will be 15 and hypotenous will be 39.
Now, consider the trigonometric ratio of cos.

What is the sum of the Arithmetic Sequence?
The formula for sum of an arithmetic sequence is;
Sₙ =ⁿ/₂(2a + (n − 1)d)
where;
a is first term
d is common difference
n is position of term
We are given the sequence as;
(x + 1) + (x + 4) + (x + 7) +...+ (x + 40) = 442
The common difference is;
x + 4 - (x + 1)
= 3
Now, to get the number of terms, we will say that the function follows the pattern;
aₙ = (x + 1) + 3n
Thus;
(x + 1) + 3n = x + 40
3n = 39
n = 13
Thus, there are n = 13 terms
Sₙ = ¹³/₂(2(x + 1) + (14 − 1)3) = 442
6.5(2x + 40) = 442
2x + 40 = 442/6.5

Answers
The polynomial f(x) of degree 5 that has the following zeros is
f(x) = (x+2) (x-3) (x-7)(x-0) (x-4).
What is meant by polynomial?Using mathematical operations like addition, subtraction, multiplication, and division, a polynomial is an expression made up of variables, constants, and exponents. In many branches of mathematics and science, polynomials are used. For instance, they are used to define polynomial functions, which show up in settings ranging from basic chemistry and physics to economics and social science. They are also used in calculus and numerical analysis to approximate other functions. Polynomial equations are used to form these functions.
The function's zeros are expressed as follows:
f(x) = (x-a)(x-b)..... where the a, b are the zeros
f(x) = (x-(-2)) (x-3) (x -7)(x-0) ( x-4)
f(x) = (x+2) (x-3) (x-7)(x-0) (x-4)
Therefore, the polynomial f(x) of degree 5 that has the following zeros is
