x power 3(x cube)- 6x -72=0 there it has change to quadratic equation x power 3(x cube)-12x+6x-72=0
Answer:
4.6
Step-by-step explanation:
Y needs to = 72. When x=5, Y = X3 - 6X Y = 53 - 6(5) Y = 125 - 30 = 95 95 > 72 95 is way too high so we try a lower number
When x=4 Y= X3 -6X Y = 43 - 6(4) Y = 64 - 24 Y = 40 40 < 72 40 is way too low so we try a higher number, 4.5
When x=4.5 Y = X3 - 6(4.5) Y = 4.53 - 6(4.5) Y = 64.125 64.125 < 72 64.125 is too low so we try a slightly higher number: 4.6
When x=4.6 Y = X3 - 6(X) Y = 4.63 - 6(4.6) Y = 97.336 - 27.6 Y = 69.736 69.736 < 72 69.736 is too low so we try a slightly higher number
When x=4.7 Y = X3 - 6(X) Y = 4.73 - 6(4.7) Y = 103.823 - 28.2 Y = 75.623 75.623 > 72 75.623 is too high so we should try a number in between 4.6 and 4.7
When x=4.65 Y = X3 - 6(X) Y = 4.653 - 6(4.65) Y = 100.54 - 27.9 Y = 72.64 72.64 > 72 72.64 is too high so to 1 decimal place, the solution to the equation is 4.6.

A(1) =5/3 a(n) =a(n-1) x-9
Answers
Step-by-step explanation:
It looks like you have provided the recursive formula for a sequence, with the initial condition of A(1) = 5/3.
To find the values of the sequence, we can use the recursion formula, which tells us that each term in the sequence is equal to the previous term multiplied by x-9. We can start by finding A(2), which will be:
A(2) = A(1) x (x-9)
A(2) = (5/3) x (x-9)
We can continue this process to find the next terms in the sequence. We can express A(3) in terms of A(2), and then A(4) in terms of A(3), and so on. Here is the general expression for A(n):
A(n) = (5/3) x (x-9)^{n-1}
So, given any value of x, we can use this formula to find the nth term in the sequence.
For example, if x=2, we can find the first few terms of the sequence:
A(1) = 5/3
A(2) = (5/3) x (2-9) = -15
A(3) = (5/3) x (2-9)^2 = 135/4
A(4) = (5/3) x (2-9)^3 = -6075/8
And so on.

Answers
The value of x for which the points j(x, -8) and K(-1, -5) is parallel to the line l is -2
What is an intercept?An intercept is any point on the graph where the line or curve touches the x or y axes.
If the intercept is on the y-axis the coordinate of x is 0 and if the intercept is on the x-axis the coordinate of y is 0.
For the line l, the coordinates of the marked points are (0, 2) and (-2, -4)
The slope of the line is \(\frac{y_{2} - y_{1} }{x_{2} - x_{1} }\)
\(x_{1}\) = 0, \(x_{2}\) = -2 , \(y_{1}\) = 2, \(y_{2}\) =-4
Slope of the line = -4 -2 / -2 - 0
slope = -6/-2
slope(P) = 3
slope(R) for the line formed by the two points J(x, -8) and K(-1, -5)
R = -5 - -8 / -1 -x
R = 3/-1 -x
For two parallel lines, their slopes are equal, that is
R = P
3/-1 -x = 3
By cross multiplying
3(-1 -x) = 3
-3 -3x = 3
-3x = 3 + 3
-3x = 6
x = 6/-3
x = -2

Sabotage is the most serious threat to aviation safety. Airport security could be increased.
The relative normal probability plot of aeroplane crashes is derived by using its concept:
Error of the pilot: 503/1944 = 0.258.
90/1944 erroneous by humans: 0.046.
326/1944 = 0.167 for weather.
issues with the mechanics: 382/1944 = 0.196.
643/1944 = 0.330 sabotage.
Sabotage provide the chief concern as a result of the higher relative frequency; therefore, airport security could be increased.
Define Relative Frequency.
The number of desired outcomes divided by the total number of outcomes yields a relative frequency.

Write a porportion that you can use to convert 60 inches to centimeters
Answers
Answer:
152.4 centimeters.
Step-by-step explanation:
1 inch = 2.54 centimeters
60 inches = x centimeters
Where x is the number of centimeters equivalent to 60 inches.
To solve for x, we can set up a proportion:
1 inch / 2.54 centimeters = 60 inches / x centimeters
Cross-multiplying, we get:
1 inch * x centimeters = 2.54 centimeters * 60 inches
Simplifying, we get:
x = (2.54 cm/in) * (60 in)
x = 152.4 cm
Therefore, 60 inches is equivalent to 152.4 centimeters.

For a system of vectors u = {(1,2,6 ); (0,-1,-5); (2,3,7); (1,0,-4) } . a. find the number of dimensions and a basis w of the subspace generated by the vector system u . b. find the parameter k to u = (2, 3, k^2+1) is a linear combination of w , and deduce [u ]w
Answers
a. The subspace generated by the vector system u has 2 dimensions. A basis for this subspace is {(1, 2, 6), (0, -1, -5)}. b. The parameter k that makes u = (2, 3, \(k^2 + 1\)) a linear combination of the basis w is k = ±√6. The coordinate vector [u]w with respect to the basis w is [u]w = (2, 1).
a. To find the number of dimensions and a basis for the subspace generated by the vector system u, we need to determine the linearly independent vectors among the given vectors. Let's perform Gaussian elimination to determine the linearly independent vectors:
Row 2 = Row 2 - 0 * Row 1
= (0, -1, -5)
Row 3 = Row 3 - 2 * Row 1
= (2, 3, 7)
Row 4 = Row 4 - Row 1
= (1, 0, -4)
Row 3 = Row 3 - 2 * Row 2
= (2, 3, 7) - 2 * (0, -1, -5)
= (2, 3, 7) - (0, -2, -10)
= (2, 5, 17)
Now, we have the following row-echelon form:
(1, 2, 6)
(0, -1, -5)
(0, 0, 0)
(0, 0, -10)
We can see that there are 2 pivot columns in this row-echelon form, which indicates that the subspace generated by the vector system u has 2 dimensions.
b. To find the parameter k such that u = (2, 3, k² + 1) is a linear combination of the basis w, we can set up the following equation:
(2, 3, k² + 1) = a(1, 2, 6) + b(0, -1, -5)
This equation gives us the following system of equations:
2 = a
3 = 2a - b
\(k^2 + 1 = 6a - 5b\)
From the first equation, we can deduce that a = 2. Substituting this value into the second equation, we get:
3 = 2(2) - b
3 = 4 - b
b = 4 - 3
b = 1
Now, we can substitute the values of a and b into the third equation:
\(k^2 + 1 = 6(2) - 5(1)\\k^2 + 1 = 12 - 5\\k^2 + 1 = 7\\k^2 = 7 - 1\\k^2 = 6\)
k = ±√6
Therefore, the parameter k that satisfies u = (2, 3, \(k^2 + 1\)) as a linear combination of the basis w is k = ±√6. The coordinate vector [u]w represents the coefficients of the linear combination of the basis vectors w that yield the vector u. Using the basis w = {(1, 2, 6), (0, -1, -5)}, we can express u as:
u = a(1, 2, 6) + b(0, -1, -5)
Substituting the values of a = 2 and b = 1, we get:
u = 2(1, 2, 6) + 1(0, -1, -5)
u = (2, 4, 12) + (0, -1, -5)
u = (2, 4, 12) + (0, -1, -5)
u = (2, 3, 7)

Solve the following equation: 3.3+4x=-6.9x+6.6
Round your answer to the nearest tenth.
Answers
The solution to the equation 3.3 + 4x = -6.9x + 6.6, rounded to the nearest tenth, is x ≈ 0.3.
To solve the equation 3.3 + 4x = -6.9x + 6.6, we need to isolate the variable x on one side of the equation.
First, let's simplify the equation by combining like terms:
3.3 + 4x = -6.9x + 6.6
Next, let's move the variable terms (4x and -6.9x) to one side and the constant terms (3.3 and 6.6) to the other side:
4x + 6.9x = 6.6 - 3.3
Combine the x terms on the left side:
10.9x = 3.3
Now, divide both sides of the equation by 10.9 to solve for x:
x = 3.3 / 10.9
Using a calculator, we can find the decimal approximation of x:
x ≈ 0.3028
Rounding to the nearest tenth, the solution to the equation is x ≈ 0.3.
In summary, the solution to the equation 3.3 + 4x = -6.9x + 6.6, rounded to the nearest tenth, is x ≈ 0.3.

a spherical snowball is melting in such a manner that its radius is changing at a constant rate, decreasing from 21 cm to 14 cm in 30 minutes. at what rate, in cubic cm per minute, is the volume of the snowball changing at the instant the radius is 4 cm?
Answers
The rate at which the volume of the snowball is changing at the instant the radius is 4 cm is -(448*pi)/15 cubic cm/minute.
Melting Snowball Volume RateThe volume of a sphere is given by the formula V = 4/3 * pi * r³, where r is the radius. To find the rate at which the volume of the snowball is changing, we need to take the derivative of this formula with respect to time.
First, we can start by finding the rate at which the radius is changing by using the formula :V = (4/3) * pi * (r)³
dV/dr = 4pir²
r = 21 - (21-14)/30*t (Where t = time in minutes)
Substitute the above equation in below equation:dV/dt = dV/dr * dr/dt
=> dV/dt = 4pi(21 - (21-14)/30*t)² * -(21-14)/30
=> dV/dt = -4pi(21 - (21-14)/30*t)² / 30
At the instant the radius is 4 cm, we can substitute the value of r = 4 in above equation,dV/dt = -4pi(21 - (21-14)/30t)² / 30 = -4pi*(21-7)² / 30 = -4pi(14)² / 30 = -(448*pi)/15 cubic cm/minute.

Answer:
a = 9m
Step-by-step explanation:
You can take the volume of the water tank as the volume of a cube.
The volume of a cube with side a is given by:
V=a*a*a = a^3
To find the value of a you do a the subject of the formula:
a=(V)^{1/3}
You replace and obtain for a:
a = (729m^3)^{1/3} = 9m
hence, the rim a of the water tank is 9m
Answer: The side of the tank is 9 m.
Step-by-step explanation: A water tank is normally a cube, which means length, width and height has the same measure.
To calculate Volume of a cube:
V = length*width*height
Knowing that volume is 729 and assuming sides are x:
x*x*x = 729
x³ = 729
x = \(\sqrt[3]{729}\)
x = 9
The volume is in cubic meters, so sides of the tank measures 9 m.

In the Venn diagram, we can represent the sets a, b, and c using overlapping circles. Let's label the circles as A, B, and C, respectively. Since a is a subset of b, the circle representing a (A) will be completely contained within the circle representing b (B). This indicates that every element in a is also an element of b.
Similarly, since b is a subset of c, the circle representing b (B) will be completely contained within the circle representing c (C). This indicates that every element in b is also an element of c.
By overlapping the circles A, B, and C, we can visually represent the relationships a ⊂ b and b ⊂ c.

Answers
The interval of increase for the function f(x) = ex x8 is (0, ∞).
To determine the intervals of increase or decrease for the given function, we need to analyze the sign of the derivative.
Let's find the derivative of f(x) with respect to x:
f'(x) = (ex x8)' = ex x8 (8x7 + ex)
To determine the intervals of increase, we need to find where the derivative is positive (greater than zero).
Setting f'(x) > 0, we have:
ex x8 (8x7 + ex) > 0
The exponential term ex is always positive, so we can ignore it for determining the sign. Therefore, we have:
8x7 + ex > 0
Now, we solve for x:
8x7 > 0
Since 8 is positive, we can divide both sides by 8 without changing the inequality:
x7 > 0
The inequality x7 > 0 holds true for all positive values of x. Therefore, the interval of increase for the function is (0, ∞), which means the function increases for all positive values of x.
The function f(x) = ex x8 increases in the interval (0, ∞).

Answers
In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.
The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.
We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.
Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.
Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000
We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)
Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0
Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.

Sal is trying to determine how much fabric he will need to create the kite diagrammed below. 4 triangles connect to form a kit. the 2 top triangles each have a base of 40 centimeters and a height of 33 centimeters. the bottom 2 triangles each have a base of 40 centimeters and a height of 75 centimeters.. which expressions can he use to find the total area of the kite? check all that apply. 40 times 108 73 times 115 40 times 33 40 times 75 40 times 170 80 times 108
Answers
The total area of the kite is : 40 x 108
What is a kite?A kite is a quadrilateral with four sides and four angles.
Two sides of the quadrilateral are equal.
Analysis:
Area of 2 top triangles with 40cm base and 33 cm height = 1/2bh + 1/2bh
= bh
where b = base = 40cm h = height = 33cm
Area of 2 top triangles = 40cm x 33cm
Area of two bottom triangles with 40cm base and 75cm height
= 40cm x 75cm
= 40cm x 75cm + 40cm x 33cm
= 40cm( 75 + 33) = 40 x 108
in conclusion, the area of the kite is 40 x 108.

use the properties of integrals to verify the inequality without evaluating the integrals. 2≤ ∫1 -1 √1 x^2 dx ≤ 2√2.
Answers
To verify the inequality without evaluating the integrals, we can use the properties of integrals.
First, we know that the integral of a positive function gives the area under the curve. Therefore, the integral of √(1-x^2) from -1 to 1 gives the area of a semicircle with radius 1. This area is equal to π/2, which is approximately 1.57.
Next, we can use the fact that the integral of a function over an interval is less than or equal to the product of the length of the interval and the maximum value of the function on that interval. Since the function √(1-x^2) is decreasing on the interval [-1,1], its maximum value is at x=-1, which is √2/2.
Using this property, we have:
∫1 -1 √(1-x^2) dx ≤ (1-(-1)) * √2/2 = √2
Finally, we can use a similar argument to show that the integral is greater than or equal to 2. Therefore, we have:
2 ≤ ∫1 -1 √(1-x^2) dx ≤ √2
To verify the inequality 2 ≤ ∫(1, -1) √(1 - x^2) dx ≤ 2√2 using properties of integrals, let's first establish that the integrand is non-negative on the interval [-1, 1]. Since 0 ≤ x^2 ≤ 1, we have 0 ≤ 1 - x^2 ≤ 1, so √(1 - x^2) is non-negative.
Now, consider the areas of two squares: one with side length 2 and the other with side length √2. The area of the first square is 2² = 4, and the area of the second square is (√2)² = 2. Since the integrand lies between 0 and 1, the area under the curve is less than the area of the first square but more than half of it (as it resembles half of the first square).
Therefore, 2 ≤ ∫(1, -1) √(1 - x^2) dx ≤ 2√2, as the area under the curve is between half of the first square's area and the second square's area.
