[tex]x^{3} / y^{6}[/tex] is the simplest form

The expression is

[tex](x^{1/3 }/ y^{2/3} ) ^{9}[/tex]

We have to multiply the root of 9 with the root of the numerator and denominator.

So we will get

[tex](x^{1/3} )^{9} /( y^{2/3})^{9}[/tex]

[tex]x^{1/3*9} / y^{2/3 *9}[/tex]

We will get

[tex]x^{9/3} /y^{18/3}[/tex]

=[tex]x^{3} / y^{6}[/tex]

So now we get the equation in the simplest form in the form of x and y

The smallest amount that Caleb could have converted will be £ 59.

We are given that:

At shop A, Gavin converted £ 30 into € 36.60

At shop B, Amna converted £ 73 into € 86.14

Also, Caleb converted some pounds and got € 71.98.

Rate of conversion at shop A is:

£ 30 = € 36.60

£ 1 = € 36.60 / 30

£ 1 = € 1.22

rate of conversion at shop B is:

£ 73 = € 86.14

£ 1 = € 86.14 / 73

£ 1 = € 1.18

Now, we can see that the rate of conversion is more at shop A.

So, the smallest amount that Caleb might have converted will be:

Pounds = € 71.98 / € 1.22

Pounds = £ 59

Therefore, the smallest amount that Caleb could have converted will be £ 59.

Transformation of y= b*x into y = 2.3 *x will take place by vertical dilation by a scale factor of  2.3.

A parent function is the simplest form of a particular family of functions. A family of operations is a group of tasks with the same highest degree and therefore the same graph shape.

Function transformations "move" "resize" or "mirror" the graph of the parent function.

Mathematically speaking, the transformation of the function y = f(x) is usually y = a f(b(x + c)) + d. where a, b, c, and d are arbitrary real numbers representing transformations. Note that all outer numbers (outside the brackets) represent vertical translations, and all inner numbers represent horizontal translations. Addition and subtraction are translations, and multiplication and division are dilations. Every time a minus sign is multiplied it means  it is a reflection here,  'a' stands for vertical stretch, 'b' stands for horizontal stretch, 'c' stands for horizontal movement, 'd' stands for vertical movement

We have given two functions y=b x  and y = 2.3x which means that first, y  changes into 2.3 x  i.e., vertical dilation by a scale factor of 2.3.

The radius of each cylinder is approximately 3.49 cm and the length of the plastic strip is approximately 65.84 cm.

Cylinder is a basic 3 dimensional solid with a curved surface. A cylinder can be identified as a prism with circular base.

The cross-section of a cylinder gives a circle whose area can be represented by πr² where r is the radius of the base of the cylinder.

Here the plastic wire encloses the area of cross-section of three cylinders.

Therefore area of cross-section of one cylinder=115÷3=(115/3) cm ²

Since area of cross-section of a cylinder=πr²

Therefore πr²=(115/3)

or, r=3.4931...

or, r≈3.49 cm

Hence the radius of each cylinder is approximately 3.49 cm

Now the plastic strip covers 3 cylinders .

Circumference of each cross-section of cylinder is given by =2πr

Total length of 3  cylinders = 2πr×3 = 6πr cm

Answer:

[tex]270.33\%[/tex]

Step-by-step explanation:

so generally when we want to calculate how much "percent" a number is of another number we do, [tex]100(\frac{part}{whole})[/tex]

In this question, it's asking what percent of 182 is 492, and this wording might be a bit tricky at first. It might help a bit to reword it into, "492 is what percent of 182"

So in this question, the 492 is the part (despite it being bigger), and 182 is the whole

So now we use the equation: [tex]100(\frac{part}{whole})=100(\frac{492}{182})\approx270.33\%[/tex]

If mean is 276 yards, percentile is 80, sample mean is 290 yards then the standard deviation is equal to 16.63.

Given that mean is 276 yards, percentile is 80, sample mean is 290 yards.

We are required to find the value of standard deviation.

A Z-score is basically a numerical measurement that describes a value's relationship to the mean of a group of values.

Z=(X-μ)/σ--------1

Z score for 80th percentile is 0.842.

X is given as 290 and μ as 276.

We have to just put the values of mean and Z score in formula 1 to find the standard deviation.

0.842=(290-276)/σ

σ=14/0.842

σ=16.63

Hence if mean is 276 yards, percentile is 80, sample mean is 290 yards then the standard deviation is equal to 16.63.

The unit price of strawberries at the grocery mart is $1.5, the unit price of strawberries at the Baldwin hills is $1.30

In order to get the unit price of an item, you would have to divide the cost of the item by the total quantity bought.

With this definition, at the grocery mart

price = 2.99 dollars

quantity bought = 2

unit price = 2.99 / 2

= 1.5 dollars

At the Baldwin hills

price = 3.99 dollars

quantity bought = 3

unit price = 3.99 / 3

= $1.30

There are two values of b such that the minimum value of the function is - 1, then the solutions are b₁ = - 2 and b₂ = 2, respectively.

In this problem we know a quadratic equation of the form g(x) = x² + b · x, of which we must determine the value of b such that the y-value of the minimum is - 1. Graphically speaking, quadratic equations are represented by parabolae, which have either a minimum or a maximum know as vertex.

First, we must determine the vertex form of the equation of the parabola:

y = x² + b · x

y = x² + 2 · (b / 2) · x

y + b² / 4 = x² + 2 · (b / 2) · x + b² / 4

y + b² / 4 = (x + b / 2)²

The coordinates of the vertex are (h, k) = (- b / 2, - b² / 4). Then, the y-coordinate of the vertex is:

- b² / 4 = - 1

b² / 4 = 1

The possible values of x < 21.6.

When two mathematical statements or two numbers are compared in an unequal way, it is known as inequality in mathematics. Inequalities can generally be classified as either algebraic or numerical or as a combination of the two. When a polynomial of degree 1 is compared to another algebraic expression of a degree less than or equal to 1, this is an example of a linear inequality, which is an inequality involving at least one linear algebraic expression. Different types of linear inequalities can be represented in a number of different ways. As with multi-step linear equations, start by separating the variable from the constants when resolving multi-step linear inequalities with one variable. According to the laws of inequality, it is crucial that we remember to flip the inequality sign when multiplying or dividing with negative values while resolving multi-step linear inequalities.
