The value of  y = 57.86 when x = 1331.

We are given that y varies directly as the cube root of x. This means that the equation relating y and x is of the form:

y = k * cube_root(x)

Where k is the constant of proportionality. We are also given that y = 100 when x = 6859. We can use this information to find the value of k:

100 = k * cube_root(6859)

k = 100 / cube_root(6859)

k = 100 / 19

k = 5.26

Now we can use the value of k to find y when x = 1331:

y = 5.26 * cube_root(1331)

y = 5.26 * 11

y = 57.86

Therefore, y is approximately 57.86 when x is 1331. We can round this answer to two decimal places to get:

y = 57.86

In regards to question A:

P(G) = 0.2

P(W) = 0.32

P(B) = 0.48

B: we can estimate that the friends will choose approximately 90 glass beads, 144 wood beads, and 216 brass beads if they select a total of 450 beads from the crate.

a. The probability model for choosing a bead can be represented by a discrete probability distribution, where the sample space consists of the three types of beads - glass, wood, and brass - and the probabilities of selecting each type are proportional to their respective frequencies. Let P(G) denote the probability of selecting a glass bead, P(W) denote the probability of selecting a wood bead, and P(B) denote the probability of selecting a brass bead. Then:

P(G) = [tex]\frac{60}{300}[/tex] = 1 ÷ 5 = 0.2

P(W) = [tex]\frac{96}{300}[/tex] = 8 ÷ 25 = 0.32

P(B) = [tex]\frac{144}{300}[/tex] = 12÷ 25 = 0.48

b. To estimate the number of each type of bead that will be chosen if the friends select a total of 450 beads from the crate, we can use the probabilities calculated above to find the expected number of beads of each type. Let X_G, X_W, and X_B denote the random variables representing the number of glass, wood, and brass beads, respectively, that are selected out of the 450 total selections. Then:

E(X_G) = P(G) × 450 = (1 ÷ 5) × 450 = 90

E(X_W) = P(W) × 450 = (8 ÷ 25) × 450 = 144

E(X_B) = P(B) × 450 = (12 ÷ 25) × 450 = 216

Therefore, based on the frequencies in the table, we would expect approximately 90 glass beads, 144 wood beads, and 216 brass beads to be chosen if the friends select a total of 450 beads from the crate.

Ramu bought 12 metre long ribbon, and he cut it into different pieces then the length of remaining ribbon is equals to the 10 metre.

Ramu bought a long ribbon with lengths in meters. We have to calculate the length of remaining ribbon.

Total length of ribbon, L = 12 meters

After that he cut it into 2 and 3 by 4 m and 1 and 1 by 2 meter long. Two pieces of ribbon has length of 3/4 metre in each piece. So, total length of two pieces

= 2×3/4 = 3/2 meters

Also, he cut one piece of ribbon

length of this piece = 1/2 meter

Thus, total length of cutting pieces of ribbon = 3/2 metre + 1/2 metre

= 4/2 = 2 metre

The length of remaining ribbon = total length of ribbon - cutting pieces length

= 12 metre - 2 metre

= 10 metre

Answer:

Molly is correct in stating that the two functions are not inverses of each other.

To be inverses of each other, two functions must satisfy the property that when they are composed in either order, they result in the identity function, which is represented by f(x) = x.

In this case, we have:

f(g(x)) = (x + 5) + 5 = x + 10

g(f(x)) = (x + 5) + 5 = x + 10

Since both compositions of the functions result in x + 10, which is not equal to x, the two functions are not inverses of each other.

Step-by-step explanation:

Answer:

Molly is correct. The fact that $f(g(x)) = g(f(x)) = x+5$ indicates that the two functions, $f$ and $g$, are symmetric about the line $y=x$, which means that they are not inverses of each other.

To determine whether two functions are inverses of each other, we need to show that their composition results in the identity function. That is, if $f(x)$ and $g(x)$ are two functions, then $f(g(x)) = g(f(x)) = x$ for all $x$ in the domain of $f$ and $g$.

In this case, we see that $f(g(x)) = g(f(x)) = x+5$, which is not the identity function. Therefore, the two functions are not inverses of each other.

The given functions f(x) = x² + 4x – 5 and g(x) = x - 1 are to be evaluated.
(f+g)(9). The addition of two functions is denoted by (f+g)(x) = f(x) + g(x). Now, we need to find the value of (f+g)(9). Substituting the values in the formula, we get:
(f+g)(x) = f(x) + g(x)f(x) = x² + 4x – 5g(x) = x - 1
(f+g)(9) = f(9) + g(9) = (9)² + 4(9) – 5 + (9) - 1= 81 + 36 – 5 + 9 - 1= 120
Therefore, (f+g)(9) = 120.

The subtraction of two functions is denoted by (f-g)(x) = f(x) - g(x). Now, we need to find the value of (f-9)(9). Substituting the values in the formula, we get:(f-g)(x) = f(x) - g(x)f(x) = x² + 4x – 5g(x) = x - 1(f-9)(9) = f(9) - g(9) = (9)² + 4(9) – 5 - (9) + 1= 81 + 36 – 5 - 9 + 1= 104
Therefore, (f-9)(9) = 104.3. (fog)(9)The composition of two functions is denoted by (fog)(x) = f(g(x)). Now, we need to find the value of (fog)(9).
Substituting the values in the formula, we get:
(fog)(x) = f(g(x))
f(x) = x² + 4x – 5
g(x) = x - 1
(fog)(9) = f(g(9)) = f(9 - 1) = f(8)= 8² + 4(8) – 5= 64 + 32 – 5= 91
Therefore, (fog)(9) = 91.4. g(x) = x - 1
Now, we need to evaluate g(9). Substituting x = 9 in the formula, we get:
g(x) = x - 1
g(9) = 9 - 1= 8
Therefore, g(9) = 8.

When x=6, the value of [tex]y=ax^2[/tex] is 11a.

What is expression?

One or more variables or numbers are combined with one additional action to form an expression.

Assuming that the function [tex]y=ax^2[/tex] is defined for all real numbers x, we can use the pattern of the differences of consecutive y-values to write an expression for y when x=6.

The differences of consecutive y-values for the function y=ax^2 are given by:

[tex]a(2^2 - 1^2), a(3^2 - 2^2), a(4^2 - 3^2), ...[/tex]

Simplifying these expressions, we get:

3a, 5a, 7a, ...

We can see that the differences between consecutive values are all the same, namely 2a. Therefore, we can express any y-value of the function

[tex]y=ax^2[/tex] as:

y = y(1) + (x-1)Δy

where y(1) is the value of y when x=1, and Δy is the common difference between consecutive y-values, which in this case is 2a.

Substituting the values x=6, y(1)=a(1^2)=a, and Δy=2a into this expression, we get:

y = a + (6-1)(2a) = a + 10a = 11a

Therefore, when x=6, the value of [tex]y=ax^2[/tex] is 11a.

slope of line = 7/3

y-intercept is = 7

This is the equation of the line passing through the point P (2,1,-1) and orthogonal to the plane 2x-y+3z=10.

The equation of the line passing through the point P (2,1,-1) and orthogonal to the plane 2x-y+3z=10 can be found using the X=P+TD vector equation. In this equation, X represents the point on the line, P represents the point through which the line passes, T represents a scalar parameter, and D represents the direction vector of the line.

To find the direction vector of the line, we can use the normal vector of the plane, which is given by the coefficients of the x, y, and z terms in the equation of the plane. The normal vector of the plane is (2,-1,3).

Since the line is orthogonal to the plane, the direction vector of the line will be parallel to the normal vector of the plane. Therefore, the direction vector of the line is also (2,-1,3).

Now, we can plug in the values of P and D into the X=P+TD equation to find the equation of the line:

X = (2,1,-1) + T(2,-1,3)

X = (2+2T, 1-T, -1+3T)

The equation of the line in parametric form is:

x = 2+2T
y = 1-T
z = -1+3T

To determine if Mr. Khumalo will have sufficient funds to fence off the garden,

We need to calculate the total cost of the fence excluding the cost of the gate.

Let's assume the length of the garden is L meters.

The perimeter of the garden is then 2L + 1.2 meters (due to the gate on one side).

If the cost of fencing per meter is R, then the total cost of the fence will be:

Cost of the fence.

= (2L + 1.2) × R

Since Mr. Khumalo has a budget of R30000, we can set up an inequality to determine if the cost of the fence is within his budget:

(2L + 1.2) × R + 500 ≤ 30000

Simplifying the inequality, we get:

(2L + 1.2) × R ≤ 29500

To find the equation for the line that passes through the point (3, -2) and is perpendicular to the line x = 2, we need to find the slope of the perpendicular line and use the point-slope form of an equation.

The slope of the line x = 2 is undefined, since it is a vertical line. A line that is perpendicular to a vertical line is a horizontal line, and the slope of a horizontal line is 0.

Using the point-slope form of an equation, y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line, we can plug in the values for the slope and the point:

y - (-2) = 0(x - 3)

The average rate of change of a function f(x) over an interval [a,b] is given by the formula:
average rate of change = (f(b) - f(a)) / (b - a)

In this case, we are given the function f(x)=x^2+3x+1 and the interval [−5,−3], so we can plug in the values into the formula:
average rate of change = (f(−3) - f(−5)) / (−3 - (−5))

f(−3) = (−3)^2 + 3(−3) + 1 = 9 − 9 + 1 = 1
f(−5) = (−5)^2 + 3(−5) + 1 = 25 − 15 + 1 = 11

Now, we can plug these values back into the formula:
average rate of change = (1 - 11) / (−3 - (−5)) = (−10) / 2 = −5
