What is the minimum number of lawns Wallace must mow in order for him to earn at least $8?

The slopes at the given point are -4 in the x-direction and -2 in the y-direction, and the first partial derivatives of f(x, y, z) are as above.

To find the slope of the surface in the x and y-directions at the point (-2, 1, 3) for the function h(x,y) = x^2 - y^2, we need to find the partial derivatives with respect to x and y at that point.

The partial derivative of h with respect to x is 2x, so at the point (-2, 1, 3), the slope in the x-direction is:

2x = 2(-2) = -4

The partial derivative of h with respect to y is -2y, so at the point (-2, 1, 3), the slope in the y-direction is:

-2y = -2(1) = -2

Therefore, the slope in the x-direction is -4 and the slope in the y-direction is -2.

For the function f(x, y, z) = 3x^2y - 5xyz + 6yz^2, we need to find the first partial derivatives with respect to x, y, and z.

The partial derivative of f with respect to x is:

6xy - 5yz

The partial derivative of f with respect to y is:

3x^2 - 5xz + 12yz

The partial derivative of f with respect to z is:

-5xy + 12yz

Therefore, the first partial derivatives of f with respect to x, y, and z are:

f_x(x,y,z) = 6xy - 5yz
f_y(x,y,z) = 3x^2 - 5xz + 12yz
f_z(x,y,z) = -5xy + 12yz

To find the slope of the surface h(x, y) = x^2 - y^2 at the given point (-2, 1, 3), we need to compute the first partial derivatives with respect to x and y.

For the slope in the x-direction, we calculate the partial derivative with respect to x:
∂h/∂x = 2x

At the point (-2, 1, 3), ∂h/∂x = 2(-2) = -4.

For the slope in the y-direction, we calculate the partial derivative with respect to y:
∂h/∂y = -2y

At the point (-2, 1, 3), ∂h/∂y = -2(1) = -2.

Now, let's find the first partial derivatives for the function f(x, y, z) = 3x^2y - 5xyz + 6yz^2.

∂f/∂x = 6xy - 5yz
∂f/∂y = 3x^2 - 5xz + 6z^2
∂f/∂z = -5xy + 12yz

So, the slopes at the given point are -4 in the x-direction and -2 in the y-direction, and the first partial derivatives of f(x, y, z) are as above.

Step-by-step explanation:

To figure out if something is increasing or decreasing, you must read the graph from left to right. If it appears to be going down, then it is decreasing. When it appears to be to be going up, it is increasing. For both A & B, the graph is decreasing. When you look from when the x-values are between 2.5 and 3.5, you can see the line going down. That means it is decreasing.

The y- intercept could only be: B) (0, -3).

Step-by-step explanation:

The Y intercept is found when X=0, so the first value in the ordered pair must be 0. Because the line crosses the y axis BELOW the x axis, the value must be negative. Therefore, out of all the provided options, the answer could only be (0,-3).

Answer:

The cube root of a number x is the length of the side of a cube whose volume is x cubic units.

The square root of a number x is the length of the side of a square whose area is x square units.

Hence the words ‘cube’ and ‘square’.

Mathematicians have then generalized these two concepts for when x is not necessarily a volume of a cube or an area of a square

Answer:

d = negative 5 cosine (StartFraction pi Over 2 EndFraction t)  [y=-5*cos(π/2)]

Step-by-step explanation:

See the attached graph for the explanation.  Desmos graphing software was used to plot the 4 equation options (using x in place of t and y in place of d).

The given points were added to see which of the graphed lines they best match.  We can see that the third option, y=-5*cos(π/2), intersects all four points.

Two of the options (1st and 3rd) lie too close to y=0 to see their difference on the scale of the graph, so we can eliminate them.  (Options 1 and 3)

Option 2 has an amplitude higher than the given points, so it can also be eliminated.

y=-5*cos(π/2) best represents the given points.

In a case whereby triangle ABC is congruent to triangle DEC, angle B = 2x + 31 and angle E = 7x - 24, the X is 11.

It should be noted that when a Triangles are exactly the same in term of size and shape then it is congruent.

Since the angle E and angle B is the same, then we can equate it so that we can find the value of X , then this can be calculated as

(2x + 31) = (7x - 24)

The we have

(7x - 2x) = (31 +24)

The we will have

(5x) =( 55)

Then

x = 11
