If a roll of 16m of this wire cost 3214 how much will jermaine's father spend for the wire
That 16 meters of electric wire costs 3214, one meter of electric wire costs 3214/16 = 200.6875.
To find the expense of 11 meters of wire, increase the expense per meter by 11:
Cost of 11 meters of wire = 11 * 200.6875 = 2,207.5625
Thus, Jermaine's dad will burn through 2,207.5625 for 11 meters of wire.
The expense of 16 meters of electric wire is 3214, so the expense per meter can be determined by separating the complete expense by the quantity of meters: 3214/16 = 200.6875. To find the expense of 11 meters of wire, we increase the expense per meter by 11: 200.6875 * 11 = 2,207.5625. This implies that Jermaine's dad will burn through 2,207.5625 for 11 meters of wire. This computation gives the expense of the wire in view of a known cost for every meter, permitting us to effortlessly gauge the expense of various lengths of wire.

find an equation for the sphere with center (-2,3,1) that is tangent to the xz plane
(x + 2) ^2 + (y - 3) ^2 + (z - 1^2 = 1 is an equation for a sphere with a center of (-2,3,1) and a tangent to the xz plane.
What is equation?An algebraic equation, also known as a polynomial equation, is a mathematical equation of the form P=0, where P is a polynomial with coefficients in some field, most commonly the field of rational numbers.
Here,
The equation of a sphere with center (x0, y0, z0) and radius r is given by:
(x - x0)^2 + (y - y0)^2 + (z - z0)^2 = r^2
In this case, the center of the sphere is (-2, 3, 1) and it is tangent to the xz plane, which has equation z = 0. Hence, the sphere must have a z-coordinate of 1, so the equation becomes:
(x + 2)^2 + (y - 3)^2 + (z - 1)^2 = r^2
We need to find the value of r such that the sphere is tangent to the xz plane. If a sphere is tangent to a plane, it means that the distance between the center of the sphere and the plane is equal to the radius of the sphere. The distance between a point (x0, y0, z0) and the plane z = k is given by |z0 - k|. Hence, the distance between the center of the sphere (-2, 3, 1) and the xz plane is given by:
|1 - 0| = 1
Therefore, the radius of the sphere is equal to 1, so the equation of the sphere is:
(x + 2)^2 + (y - 3)^2 + (z - 1)^2 = 1^2
Simplifying, we obtain the equation of the sphere:
(x + 2)^2 + (y - 3)^2 + (z - 1)^2 = 1 is an equation for the sphere with center (-2,3,1) that is tangent to the xz plane.

increasing at a rate of 10% per year.
City B has a population that can be modeled
B (t) = 350,000 (0. 97)' where t represents the number of years since
2018.
What is the initial population of city A ?
The initial population of city A is 175,000 while its growth rate is 10%. The function that models the population of city B is B(t) = 350,000(0.97)^t, which is a case of exponential decay.
How to find the initial population?Here since nothing else is mentioned we will assume the Initial population of city A to be that of 2018, which is 175,000.
The growth rate of any city will be the percentage increase in its population every year. Here it is mentioned that the population of city A increases by 10% every year. Hence, the growth rate of city A is 10%.
Here we are already given that the function of the population of city B in a year is B(t) = 350,000(0.97)^t.
In model B(t) with every successive increase in time, the value of (0,97)^t will keep on reducing. Due to this, the product of 350,000(0.97)^t will reduce. Hence this is a case of exponential decay.

No rational roots based on Rational Root TheoremBased on Descartes Rules of Signs has 1 positive roots and 2 or 0 negative rootsTo solve this proble, we will use Rational Root Theorem and Descartes Rules of Signs.
Based on Rational Root Theorem, we can find that the function c(x) has rational roots of:
c(x) = 18x³ + 9x² - 2x -1
possible roots = ± {factors of a₀} / {factors of aₙ}
From the given function, we can use the possible roots concept:
Possible roots = ± factors of 18
factors of 1
Possible roots = ± {1, 2, 3, 6, 9, 18}
{1}
We can conculde some possible roots such as: {-18, -9, -6, -3, -2, -1, 1, 2, 3, 6, 9, 18}
Next, we need to confirm which possible roots are the rational roots by subtitute the possible roots into the function c(x). The rational roots will produce the function equals to zero (0).
c(1) = 18(1)³ + 9(1)² - 2(1) -1
c(1) = 18 + 9 - 2 - 1 = 24 --> irrational roots
c(2) = 18(2)³ + 9(2)² - 2(2) -1
c(2) = 18(8) + 9(4) - 2(2) - 1
c(2) = 144 + 36 - 4 - 1 = 175 --> irrational roots
c(3) = 18(3)³ + 9(3)² - 2(3) -1
c(3) = 18(27) + 9(9) - 2(3) - 1 = 560 --> irrational roots
c(6) = 18(6)³ + 9(6)² - 2(6) -1
c(6) = 4.199 --> irrational roots
c(9) = 18(9)³ + 9(9)² - 2(9) -1
c(9) = 13,832 --> irrational roots
c(18) = 18(18)³ + 9(18)² - 2(18) -1
c(18) = 107,855 --> irrational roots
c(-1) = 18(-1)³ + 9(-1)² - 2(-1) -1
c(-1) = -18 - 9 + 2 - 1 = -8 --> irrational roots
c(-2) = 18(-2)³ + 9(-2)² - 2(-2) -1
c(-2) = -105 --> irrational roots
c(-3) = 18(-3)³ + 9(-3)² - 2(-3) -1
c(-3) = -400 --> irrational roots
c(-6) = 18(-6)³ + 9(-6)² - 2(-6) -1
c(-6) = -3,553 --> irrational roots
c(-9) = 18(-9)³ + 9(-9)² - 2(-9) -1
c(-9) = -12,376 --> irrational roots
c(-18) = 18(-18)³ + 9(-18)² - 2(-18) -1
c(-18) = -120,176 --> irrational roots
Next, we will try to use Descartes Rule of Signs:
c(x) = 18x³ + 9x² - 2x -1
c(x) = +18x³ + 9x² - 2x -1
The sign is changing once, then the function c(x) has 1 positive roots.
Next, we change the value of (x) into (-x) and put it into the function:
c(-x) = 18(-x)³ + 9(-x)² - 2(-x) -1
c(-x) = -18x³ + 9x² + 2x -1
The signs are changing twice on between the first and second coefficient and between third and fourth. Hence the funciton c(x) has 2 or zero negative roots.

As x increases from x=1 to x=5, the value of h remains constant at 4 and the output of the function v(x) changes from v(1) = 5 to v(5) = 29, with a difference of 24.
A function is a mathematical rule that assigns a unique output for every input.
Given the function h = 4, we can see that the output is always 4, regardless of the input value.
Now, if we consider the function
=> v(x) = x² + h,
we can see that the output is dependent on the input x and the constant value of h. As x increases from x=1 to x=5, the output of v(x) will also change.
We can calculate the value of v(1) as
=> v(1) = 1² + 4 = 5.
And similarly, we can calculate the value of v(5) as
=> v(5) = 5² + 4 = 29.
The difference between v(5) and v(1) can be calculated as
=> v(5) - v(1) = 29 - 5 = 24.
This represents the change in the output of the function v(x) as x increases from x=1 to x=5.

AG² = AB² + GB² = 32² + 22² = 1024 + 484 = 1508
AG = sqrt(1508) = 38.83297568...
if you round to hundredths : 38.83
In AGHI, g = 91 cm, h = 73 cm and i=73 cm. Find the measure of ZG to
the nearest 10th of a degree.
The measure of the angle ∠G nearest to tenth place will be 77.1°.
What is the cosine law?The squared of the size of any solitary side of either a triangle is equal, by the cosine rule, to the total of the squares of the lengths of the other two sides, times by the cosine of something like the angle they are a part of.
Let the triangle ΔABC, then the cosine law is given as,
c² = a² + b² - 2 a·b cos C
In ΔGHI, g = 91 cm, h = 73 cm and i = 73 cm. Then the measure of the angle ∠G is given as,
g² = h² + i² - 2 h·i cos G
(91)² = (73)² + (73)² - 2 x 73 x 73 cos G
8281 = 5329 + 5329 - 10658 cos G
10658 cos G = 5329 + 5329 - 8281
10658 cos G = 2377
cos G = 0.223
cos G = cos 77.1°
The measure of the angle ∠G nearest to tenth place will be 77.1°.

What are the points of an image A(-3,-2) B(-3,1) C(0,3) and D(2,-1), after a dilation and a scale factor of 2?
Answer: In a dilation with scale factor k, each point (x,y) is transformed to the point (kx,ky). So, if the scale factor is 2, the points A, B, C, and D will be transformed to the following:
A' (-3 * 2, -2 * 2) = (-6, -4)
B' (-3 * 2, 1 * 2) = (-6, 2)
C' (0 * 2, 3 * 2) = (0, 6)
D' (2 * 2, -1 * 2) = (4, -2)
So, the image points after the dilation with scale factor 2 are A' = (-6,-4), B' = (-6,2), C' = (0,6), and D' = (4,-2).
Step-by-step explanation:
Harper is starting a new T-shirt printing business. She
purchases plain T-shirts for $5 each and spends $150
for printing equipment. She decides to sell printed shirts
for $10 each. How many T-shirts does Harper need to
sell so that the amount of money she spends to start
her business and the amount of money she earns are
the same?
Using algebraic expression, She needs to sell 150 / 5 = 30 T-shirts.
What do you mean by Algebraic Expression?An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations (such as addition, subtraction, multiplication, and division). It represents a value that can be determined if the values of the variables are known. An algebraic expression does not contain an equal sign and cannot be solved like an equation, but it can be simplified or manipulated using algebraic rules. For example, the expression 2x + 3y is an algebraic expression, where x and y are variables.
Harper's fixed costs for starting the business are $150.
She earns $10 for each T-shirt sold, and she spends $5 on each T-shirt she buys.
So, her profit is $10 - $5 = $5 per T-shirt.
To break even, Harper needs to earn enough money from selling T-shirts to cover her fixed costs of $150.
Therefore, she needs to sell 150 / 5 = 30 T-shirts.

In testing the equality of population proportions using chi-square, how many categories or populations do you need to be able to perform this analysis? at least 2 at least 4 greater than 3 at least 3
In testing the equality of population proportions using chi-square, at least 3 categories or populations need to be able to perform this analysis
Now, According to the question:
A chi-square test for equality of two proportions is exactly the same thing as a z-test. The chi-squared distribution with one degree of freedom is just that of a normal deviate, squared. You're basically just repeating the chi-squared test on a subset of the contingency table.
The chi-square test is used to compare more than two independent populations. The test is pretty similar to that of two population proportions except for the fact that the contingency table involved in the study includes 2 rows and c number of columns indicating the number of populations.

Find a domain for the quantifier in ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) uch that thi tatement i true
So, the domain for the quantifier in ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) is the set of all non-empty sets.
The quantifier ∃x∃y(x ≠ y ∧ ∀z((z = x) ∨ (z = y))) is a statement in first-order logic that says "there exists x and there exists y such that x is not equal to y and for all z, z is equal to x or z is equal to y".
The domain for this quantifier is the set of all values for which the statement inside the quantifier is true.
In this case, the domain for the quantifier is the set of all non-empty sets, since for any non-empty set, we can find at least two distinct elements x and y, such that x is not equal to y and for any element z in the set, either z is equal to x or z is equal to y.

Three different linear functions are represented in the table. Which is the correct order of the functions from least to greatest steepness with respect to rate of change?.
A linear function is used to depict a relationship between two variables where one variable influences the other.
What is meant by linear functions?Those with a straight-line graph are considered to be linear functions. This is the format of a linear function. y = f(x) = a+bx. The only independent and only dependent variables in a linear function are both independent.
In a relationship between two variables, where one variable affects the other, a linear function is used to represent the relationship. Generally speaking, x and y are the independent and dependent variables, respectively, in a linear function (x influences y).
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.
