The directional derivative of f(x, y, z) = y^2 – 2x^2 + z^2 at the point P = (-5, 2, 1) in the direction of the origin is 30√(30).

The directional derivative of a function f(x, y, z) in the direction of a vector u = <a, b, c> at a point P = (x₀, y₀, z₀) is given by the dot product of the gradient of f at P and the unit vector in the direction of u, which is

D_u(f)(P) = ∇f(P) · (u/||u||)

where ||u|| is the magnitude of the vector u.

In this case, we want to find the directional derivative of f(x, y, z) = y^2 – 2x^2 + z^2 at the point P = (-5, 2, 1) in the direction of the origin, which is the vector from P to the origin O = (0, 0, 0).

The vector from P to O is u = <0-(-5), 0-2, 0-1> = <5, -2, -1>, so we need to find the unit vector in the direction of u, which is:

u/||u|| = <5, -2, -1>/√(5^2 + (-2)^2 + (-1)^2) = <5/√(30), -2/√(30), -1/√(30)>

Next, we need to find the gradient of f at P = (-5, 2, 1), which is

∇f(P) = <∂f/∂x, ∂f/∂y, ∂f/∂z>(P) = <-4x, 2y, 2z>(-5, 2, 1) = <20, 4, 2>

Finally, we can compute the directional derivative of f at P in the direction of the origin as

D_u(f)(P) = ∇f(P) · (u/||u||) = <20, 4, 2> · <5/√(30), -2/√(30), -1/√(30)> = (100/√(30)) + (-8/√(30)) + (-2/√(30)) = 90/√(30) = 30√(30)

For 10 more tables, you need 40 napkins total, but we have 2, so 38 napkins is what Jonah needs with what he has.

The function’s equation written in factored form and in vertex form are respectively;

f(x) = 2x(x - 4)

f(x) = 2(x - 2)² - 8

The factored form of a quadratic function is;

f(x) = a(x - p)(x - q)

where:

p and q are the x-intercepts

a is a constant

Now, we are given x-intercepts as; (0, 0) and (4, 0)

Thus;

f(x) = a(x - 0)(x - 4)

f(x) = ax(x - 4)

To find a, substitute the given vertex (2, -8) into the equation and solve for a:

2a(2 - 4) = -8

-4a = -8

a = 2

Thus;

f(x) = 2x(x - 4)

The vertex form of a quadratic equation is;

f(x) = a(x - h)² + k

where:

(h, k) is the vertex

a is constant

Since vertex is (2, -8), then we have;

f(x) = a(x - 2)² - 8

Put the coordinate (0, 0) to find a;

0 = a(0 - 2)² - 8

4a = 8

a = 2

Thus;

f(x) = 2(x - 2)² - 8

Answer:

x=9

Step-by-step explanation:

So first, you have to add 13 to both sides to isolate the x so that will make the equation 2x=5+13. Add 5 and 13 to get 18. The equation will now be 2x=18. Divide both sides by 2 because we want x to equal one. This will make it x=18/2. Simplify that and get x=9

Hope this helps

Question

Find the value of x in 2x – 13 = 5 .

ANSWER

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication, and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

Hence, this information ( x = 9 )

202.5 / 0.25= 810

Hope this helps!

Answer:

810 miles

Step-by-step explanation:

$180 a week is the fixed cost so we subtract this first.

($382.50 - $180 = $202.50)

The number left is the amount of dollars charged per mile.

So if we divide this number by $0.25, we get how many miles travelled.

To calculate the value at the 69.5th percentile, we first need to find the rank of this percentile.
69.5th percentile = (69.5/100) x 10 = 6.95th rank  
Plugging in the values:
value = (6.95 - 6) / (7 - 6) x (44 - 37) + 37
value = 40.7
Therefore, the value at the 69.5th percentile is 40.7 gold medals.

To calculate the value at the 69.5th percentile, follow these steps:

1. Arrange the data in ascending order:
33, 34, 36, 36, 37, 37, 44, 46, 47, 83

2. Determine the position of the 69.5th percentile in the dataset:
Position = (Percentile / 100) * Total number of data points
Position = (69.5 / 100) * 10 = 6.95

Since the position is not a whole number, we'll need to interpolate between the values at positions 6 and 7.

3. Find the values at positions 6 and 7:
Value at position 6 = 37
Value at position 7 = 44
To interpolate between these two values, we use the percentile formula:
value = (rank - rank_ lower) / (rank_ upper - rank_ lower) x (value_ upper - value_ lower) + value_ lower
where:
- rank = 6.95
- rank_ lower = 6
- rank_ upper = 7
- value_ lower = 37
- value_ upper = 44

4. Interpolate between the values at positions 6 and 7:
Value at 69.5th percentile = Value at position 6 + ((Position - Position 6) * (Value at position 7 - Value at position 6))
Value at 69.5th percentile = 37 + ((6.95 - 6) * (44 - 37))
Value at 69.5th percentile = 37 + (0.95 * 7)
Value at 69.5th percentile = 37 + 6.65
Value at 69.5th percentile = 43.65

The value at the 69.5th percentile is approximately 43.65 gold medals.

The relationship of the volume between a prism and a pyramid of the same dimensions will be -  Volume of prism = 3 × volume of a pyramid.

For say, we took a right-angled prism and a right-angled pyramid with the same base and height. So, according to the formula -

Volume of prism = Base area × height

Volume of pyramid = \(\frac{1}{3}\) ×  Base area × height

(Since, the volume of prism = Base area × height)

Volume of pyramid = \(\frac{1}{3}\) × Volume of prism  

Volume of prism = 3 × Volume of pyramid

The relation should be written as a set of ordered pairs as follows: A. . ordered pairs: {(0, 2), (2, 6), (4, 10)}.

In Mathematics, a function can be defined as a mathematical expression which is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (x-value or domain) to an output variable (y-value or range).

In Mathematics, an ordered pair is sometimes referred to as a coordinate and it can be defined as a pair of two (2) elements that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate (abscissa) and the y-coordinate (ordinate) on the coordinate plane of any graph such as the following:

To solve this problem, we'll use the formula for displacement in a uniformly accelerated motion:

s = ut + 0.5at^2

Here, s represents the displacement (2500 meters), u is the initial velocity (0 m/s since the rock is dropped), a is the acceleration due to gravity (-9.8 m/s^2), and t is the time it takes for the rock to hit the canyon floor.

1. Substitute the given values into the equation:
2500 = 0 * t + 0.5 * (-9.8) * t^2

2. Simplify the equation:
2500 = -4.9t^2

3. Isolate t^2 by dividing both sides by -4.9:
t^2 = 2500 / (-4.9) = -510.2

Since the result is negative, we made an error in the sign of the acceleration due to gravity. It should be positive as the displacement is downward, which is the same direction as gravity. So, the correct equation should be:

2500 = 4.9t^2

4. Solve for t^2:
t^2 = 2500 / 4.9 = 510.2

5. Take the square root of both sides to find t:
t = √510.2 ≈ 22.6 seconds

Therefore, it will take the rock approximately 22.6 seconds to hit the canyon floor.

-3x + -2 = -17

Reorder the terms:

-2 + -3x = -17

Solving

-2 + -3x = -17

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + -3x = -17 + 2

Combine like terms: -2 + 2 = 0

0 + -3x = -17 + 2

-3x = -17 + 2

Combine like terms: -17 + 2 = -15

-3x = -15

Divide each side by '-3'.

x = 5
