You have 2.88 meters of copper wire and 5.85 meters of aluminum wire. You need 0.24 meter of copper wire to make one bracelet and 0.65 meter of aluminum wire to make one necklace. Can you make more bracelets or more necklaces? Explain.​

According to the mathematical notations, we can say that in this case, Antonhy's reasoning is incorrect, because the expression abc is only one term and not three as he stated.

It corresponds to a term that has letters and numbers, which are separated only if there is a mathematical sign between them, such as the plus or multiplication sign, for example, to be an expression of three terms, the expression should be like this:

Therefore, we can consider that the term abc corresponds to a monomial, as it is only one term in an expression, and not three as supposed by Anthony.

On solving the provided question, we can say that volume of cylinder  =  [tex]\pi r^2h[/tex] = 13564.8

One of the most fundamental curved geometric forms is the cylinder, which is often a three-dimensional solid. It is referred to as a prism with a circle as its base in elementary geometry. Several contemporary fields of geometry and topology also define a cylinder as an indefinitely curved surface. A three-dimensional object known as a "cylinder" consists of curving surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure that has two bases that are both identical circles joined by a curving surface at the height of the cylinder, which is determined by the distance between the bases from the center. Examples of cylinders are cold beverage cans and toilet paper wicks.

volume of cylinder  =  [tex]\pi r^2h[/tex]

[tex]\pi[/tex] = 3.14

r = 15 cm\

h = 18 cm

The shortest distance between planet Q and planet R is 1.64 * 10⁷ km

An equation is an expression that shows the relationship between variables and numbers.

Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given as:

hypotenuse² = adjacent² + opposite²

From the diagram, QR is the shortest distance between planet Q and planet R. Hence using Pythagoras:

QR² = QP² + PR²

QR² = (3.6 * 10⁶)² + (1.6 * 10⁷)²

QR = 1.64 * 10⁷ km

The rule for the linear function in the table include the following: y = 2x.

In order to write a rule for the linear function, we would have to use the point-slope form formula. Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

Next, we would determine the linear function representing the relationship between the x-value and y-value in the given table as follows:

y - y₁ = m(x - x₁)

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - (-4) = (4 - (-4))/(2 - (-2))(x - (-2))

y + 4 = 8/4(x + 2)

y + 4 = 2(x + 2)

y = 2x + 4 - 4

y = 2x

The percentage and the z-scores for specific heights of the given normal distributions are as detailed below.

The first step is to draw the Normal curve with 8 regions, and then we now label the 7 vertical dividing lines with the mean plus/minus one/two/three standard deviations:

By adding the percentage values in the areas indicated in the question, we will arrive at;

The percentage of Ixxians that are;

i) Over 30 inches tall = 100% - (2.35% + 0.15%) = 97.5%

ii) Over 45 inches tall =  13.5% + 2.35% + 0.15% = 16%

iii) Under 50 inches tall = 100% - (2.35% + 0.15%) = 97.5%

iv) under 40 inches tall = 34% + 13.5% + 2.35% + 0.15% =  50%

v) between 35 and 55 inches tall = 34% + 34% +  13.5% + 2.35% = 83.85%

vi) between 25 and 35 inches tall = 13.5% + 2.35% 15.85%

The z-score is defined as the number of standard deviations above the mean corresponding to the given value. Thus;

i. For a height of 32 inches, the z-score is;

z = [32-40]/5

z = -1.6

ii. For a height of 47 inches, the z-score is;

z = [47 - 40]/5

z = 1.4

iii. For a height of 51 inches, the z-score is;

Y=5(2)-9

Y=10-9

Y=1

Answer:

Step-by-step explanation:

y = 5x - 9 (eq'n 1)

-2x - 3 = -7 (eq'n 2)

Solve for x in (eq'n 2)

-2x -3 = -7 (add 3 to both side of the eq'n)

(-2x - 3) + 3 = -7 + 3

-2x = -4 (divide both side by -2)

x = 2

Therefore the value of y is:

From  (eq'n 1), Substitute the value of x

y = 5x - 9

y = 5(2) - 9

y = 1

The derivative of y with respect to x (Dy/Dx) can be found by using implicit differentiation and is equal to (x/y)(Dx/Dx) / (3y - x - y).

The given equation is x/y + y/x = 3y.

To find the derivative of y with respect to x (Dy/Dx), we will use implicit differentiation.

First, we will take the derivative of both sides of the equation with respect to x:

(1/y) * (Dy/Dx) + (1/x) * (Dy/Dx) + (y/x^2) * (Dx/Dx) = (3)(Dy/Dx)

We can simplify this expression by combining the terms with Dy/Dx and Dx/Dx:

(Dy/Dx)(1/y + 1/x + 3) = (y/x^2)(Dx/Dx)

Now we can solve for Dy/Dx by rearranging the equation:

Dy/Dx = (y/x^2)(Dx/Dx) / (1/y + 1/x + 3)

Finally, we can plug in our known values and solve for Dy/Dx:

Dy/Dx = (x/y)(Dx/Dx) / (3y - x - y)

Therefore, the derivative of y with respect to x (Dy/Dx) can be found by using implicit differentiation and is equal to (x/y)(Dx/Dx) / (3y - x - y).

The end behavior of the graphs of polynomial functions is determined by the highest degree of the polynomial.

For example, a polynomial with degree n will eventually approach infinity as x increases or decreases without bound. This can be expressed mathematically as:

f(x) = axn -> lim x->∞ f(x) = ∞

and

f(x) = axn -> lim x->-∞ f(x) = ∞

where a is a constant.

For a polynomial of degree n, the graph will have n-1 turning points. As the degree increases, the graph approaches a smooth curve. Additionally, the graph will have either one up-turn or one down-turn depending on the sign of the leading coefficient. If the leading coefficient is positive, the graph will have an up-turn; if the leading coefficient is negative, the graph will have a down-turn.

For example, the end behavior of the graphs of the polynomial f(x) = 2x3 + 2x2 - 2x - 1 has degree 3, so it will have 2 turning points and will have an up-turn as the leading coefficient is positive.

The exponent 3 is called the power or index. It is the number that indicates how many times the base number (in this case 3) is multiplied by itself.

To determine this

For example, 3³ means 3 multiplied by itself 3 times, or 3 x 3 x 3 = 27. So 3 is the base number and 3 is the exponent or power.

In mathematical notation, the exponent is written as a small number or variable above and to the right of the base number, with a caret symbol (^) separating them. For example, 3³ is written as 3³, and x² is written as x².

Additionally, in mathematics, exponents are also used to represent the number of times a number is multiplied by itself, the exponent number represents how many times the number is being multiplied.

This is defined as the ratio of distance to time taken usually in kilometers per hour, miles per hour.

The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

How to write equation

Distance Saul biked = 300 kilometers

Number of hours it takes train travel = t

Speed of train travel (kilometers per hour) = r

Speed = Total distance travelled / Time taken

r = 300 / t

Equation that represents how many hours

Make t the subject of formula

r = 300 / t
