Answer:

[tex]r_Y=\frac{3}{\pi}[/tex]

Step-by-step explanation:

Circumference has the formula:

C = 2πr,

Where

C is the circumference

and

r is the radius

Given Circle Y has Circumference of 6, we can find the radius:

C = 2πr

6 = 2πr

r = 6/2π

r = 3/π

So, the radius (r_y) of Circle Y is 3/π, the first choice is right.

Final answer:

Georgia received 3 dimes on Tuesday, 9 on Wednesday, and 81 on Thursday, following a trend of tripling the amount each day. Continuing this pattern, she would receive 243 dimes on Friday.

Explanation:

The question involves identifying and extending a mathematical pattern. Here, we notice that the number of dimes Georgia receives each day is being multiplied by 3 to get the number of dimes for the next day. On Tuesday she received 3 dimes, on Wednesday this was multiplied by 3 to get 9 dimes, and on Thursday it was multiplied again by 3 to get 81 dimes. So, to find out how many dimes Georgia received on Friday, we simply continue this pattern and multiply Thursday's amount by 3.

3 dimes (Tuesday) * 3 = 9 dimes (Wednesday

9 dimes (Wednesday) * 3 = 81 dimes (Thursday)

81 dimes (Thursday) * 3 = 243 dimes (Friday)

Therefore, if this trend continued, Georgia would have received 243 dimes on Friday.

Step-by-step explanation:

The soil is 4 inches deep in the pot, calculated by dividing the volume of soil (48 cubic inches) by the area of the pot's base (length times width).

Ian put 48 cubic inches of soil into a flower pot. The length of the pot is 4 inches, and the width of the pot is 3 inches. To find out how many inches deep the soil is, we can use the formula for the volume of a rectangular prism, which is Volume = length times width times height. In this case, we have the volume and the dimensions for length and width, so we can solve for the height (or depth).

The formula would be:

Therefore, the soil is 4 inches deep in the pot.

The exponential expression 3^1/2 can be converted to radical form as √3. This is because the fractional exponent 1/2 equates to a square root and the base of the expression, 3, becomes the number under the square root symbol.

The expression 3^1/2 can be expressed in radical form by understanding that the exponent 1/2 represents a square root, which means the value inside the square root is being multiplied by itself to get the original number. Therefore, we rewrite this exponential term in radical form by placing the base, which is 3, under a square-root symbol, so 3^1/2 can be expressed as √3 in radical form. This is because the root, which corresponds to the denominator of the fractional exponent, is 2 (hence square root), and the radicand, which corresponds to the numerator of the fractional exponent, is 3.

Step-by-step explanation:

Given the cylinder has a base radius of 10 units.

And slant length of 26 units.

The formula for volume of an oblique cylinder is [tex]\pi r^2h[/tex]

Where [tex]r[/tex] is the radius and [tex]h[/tex] is the height of cylinder.

We will now find height of cylinder using following equation.

[tex](slant\ length)^2=(radius)^2+(height)^2[/tex]

[tex]26^2=10^2+(height)^2\\\\676=100+(height)^2\\\\676-100=(height)^2\\\\576=(height)^2\\\\\sqrt{576}=\sqrt{(height)^2}\\ \\24=height[/tex]

Now, the volume of cylinder would be

[tex]=\pi r^2h\\=\pi(10)^2\times24\\=\pi 100\times24\\=2400\pi[/tex]cubic units

The volume of the cylinder is 2,400pi cubic units

The formula for calculating the volume of a cylinder is expressed as:

V = πr²h

where:

r is the radius = 10units

h is the height

Since the cylinder is oblique, hence:

h² = 26² - 10²

h² = 676 - 100

h² = 576

h = 24 units

V = 22/7(10)² * 24

V = 2400 pi cubic units

Hence the volume of the cylinder is 2,400pi cubic units

To find the composition of two functions F(G(x)), substitute the value of G(x) into F(x). The result for F(G(x)) in this case is -10x + 38.

This question pertains to the mathematical concept of functions. Specifically, you are being asked to find the composition of two functions, F(x) and G(x).

To find F(G(x)), you substitute the value of G(x) into the function F(x). Recall that G(x) = -2x + 9. So, you need to replace 'x' in F(x) = 5x -7 by the value of G(x). Thus, F(G(x)) = 5(-2x+9) - 7 = -10x + 45 - 7 = -10x + 38.

For no solutions, the equation could be 7x + 5 = 7x + 6. For one solution, the equation could be 7x + 5 = 7x + 6. For infinitely many solutions, the equation would be 7x + 5 = 7x + 5.

The given problem is an algebraic expression which needs to be manipulated appropriately to yield No Solutions, One Solution and Infinitely Many Solutions.

Let's simplify the left-hand side expression first: 2x + 5 + 2x + 3x = 7x + 5.

For No Solutions, you would need the constant term on the right-hand side to not be equal to 5, and the coefficient of x not equal to 7, for example, 7x + 6 would yield no solutions, because there's no value of x which would make 7x + 5 equal to 7x + 6.

For One Solution, you need to make sure the right-hand side and left-hand side aren't identical. For example, 7x + 6 = 7x + 5 has one solution, x = -1.

For Infinitely Many Solutions, the equation on the right-hand side should be the same as the left-hand side. So, it would be 7x + 5 = 7x + 5 as for every real number x, these two expressions will be equal.

Step-by-step explanation:

1.

Find the least common multiple (LCM) for the denominators. Because you have to make the denominators the same before you add the fractions, find a common multiple that they share. Then choose the lowest one. In this case the LCM is 6

2. Multiply the numerator and denominator to get like denominators. You'll need to multiply the entire fraction to make the denominator become the least common multiple. In this case multiply 2/3 by 2 = 4/6

3. Add the two fractions and the whole numbers

In this case: 2+ 3 =5

4/6 + 5/6 = 9/6

4. Now you have

5 + 9/6

5. Simplify 9/6 to 1 3/6 = 1 1/2

6. Add 5 + 1 1/2 = 6 1/2

Kristin has approximately 4 yards of plaid ribbon and 3 yards of polka-dot ribbon after rounding fractions to the nearest whole number, which totals to about 7 yards of ribbon in all. This estimation method is reasonable for handling fractions.

We are asked to estimate the total amount of ribbon Kristin has by adding together 3 2/3 yards of plaid ribbon and 2 5/6 yards of polka-dot ribbon. To estimate, we round each fraction to the nearest whole number. The 2/3 in 3 2/3 rounds up to 1, making it approximately 4 yards. The 5/6 in 2 5/6 rounds up to 1, making it approximately 3 yards. Adding these estimates together gives us 4 yards of plaid ribbon plus 3 yards of polka-dot ribbon, which equals to about 7 yards of ribbon in total.

Our estimate is reasonable because we rounded each fraction up to the nearest whole number, making for easy addition. It's also a common method to simplify calculations and get a sense for the magnitude of the sum. Since our original fractions were more than 1/2 (3/2 is 1 1/2, and 5/6 is nearly 1), rounding up provides a reasonable overestimate likely very close to the actual sum.

Opposite numbers are defined as those numbers that are in opposite positions on a number line, but their distance from zero is the same. Then, one of them is positive and the other one is negative.

The sum of opposite numbers is zero.

For example, the following numbers are opposite:

 [tex]8[/tex] and [tex]-8[/tex]

It's a bit hard to tell what constitutes an "iteration" when using the bisection method to approximate a polynomial root. For the purpose here, we'll say one iteration consists of ...

Thus, the result of the iteration consists of a bracketing interval and the choice of one of the interval's ends as the solution approximation.

__

(a) We observe that the graphs intersect in the interval (-1, 0). For the first iteration, we evaluate f(x)-g(x) at x=-1/2. This tells us the solution is in the interval (-1, -1/2). The x-value closest to the root is x=-1/2.

For the second iteration, we evaluate the function f(x)-g(x) at x=-3/4. This tells us the solution is in the interval (-1, -3/4). The x-value closest to the root is x=-3/4.

For the third iteration, we evaluate the function f(x)-g(x) at x=-7/8. This tells us the solution is in the interval (-7/8, -3/4). The x-value closest to the root is x=-3/4.

__

(b) The graph tells us the solution is approximately 0.7549. Rounded to 2 decimal places, the solution is approximately 0.75.

__

(c) The above solution found after 3 iterations rounded to 2 decimal places is exactly 0.75.

__

See the attached table for function values.

_____

Comment on bisection iteration

Since you cut the interval containing the root in half with each iteration, you gain approximately one decimal place for each 3 iterations. When the function value is very nearly zero at one of the interval endpoints, it can take many more iterations to achieve a better result.

Here, it takes 4 more iterations before an x-value becomes closer to the solution (x≈-97/128). And it takes one more iteration to move the end of the interval away from -3/4. After these 5 more iterations (8 total), the solution is known to lie in the interval (-97/128, -193/256). The corresponding solution approximation is -193/256. It is still only correct to 2 decimal places.

If Crystal sold b number of balloons then;

a) Number of balloons Aliya sold is 2 more than Crystal's .This means Aliya sold two more balloons added to what Crystal sold.mathematically, it will be = 2+b

b) Number of balloons Shamika sold is twice Crystal's.This means Shamika sold double the number of balloons Crystal sold.If Crystal sold b balloons, twice this number is =2b

c)Total number of balloons sold will be presented by the expression;

=b+2+b+2b=4b+2

The expression for total cost will be;

$2*(4b+2) =$900----------------------expression

d) solving the expression for total cost as

   2(4b+2)=900

    8b+4=900

     8b=900-4

     8b=896 -------divide both sides by 8 to get b

    b=896/8 =112 balloons  ----------value of variable b

e)

Crystal sold  b  balloons = 112 balloons

Shamika sold, 2b, =2*112 = 224 balloons

Aliya sold , 2+b balloons = 2+112 =114 balloons

f)By solving the expression for total cost , you obtain the value of variable b which represents the number of balloons sold by Crystal. Using the value of b, you can calculate the number of balloons for Shamika and Aliya using their expressions which represent number of balloons they sold.
