The acute angles between two curves at their points of intersection can be found by calculating the angles between the tangent lines of the two curves at those points. To calculate this angle you will need to calculate the gradient of the tangent lines at each point of intersection. To do this, you need to take the derivative of each curve's equation at each point of intersection. Once you have the gradients, you can then use the equation for the angle between two lines to calculate the angle between the two tangent lines. Then, the angles should be rounded to one decimal place and given in a comma-separated list.

b = (2,-1,6) is a linear combination of a1 = (1,-2,0), a2 = (0,1,2) and a3 = (5,-6,8) with weights (1,3,1) respectively.

To determine if b is a linear combination of a1, a2, and a3, we can set up a system of equations using the coefficients of the linear combination and the variables a1, a2, and a3. The equation for a linear combination of the form b = k1a1 + k2a2 + k3a3, where k1, k2 and k3 are the coefficients, can be written as:

b = k1 × (1,-2,0) + k2 × (0,1,2) + k3 × (5,-6,8)

So,

x = k1 + 5k3

y = -2k1 + k2 - 6k3

z = 2k2 + 8k3

We know the values of x,y,z from b = (2,-1,6)

So, we can set up the following system of equations:

x = k1 + 5k3 = 2

y = -2k1 + k2 - 6k3 = -1

z = 2k2 + 8k3 = 6

We can solve the system of equations using methods such as substitution or elimination to find the values of k1, k2, and k3.

k1 = 1, k2 = 3, k3 = 1

Therefore, we can express b as a linear combination of a1, a2, and a3 with the weights k1, k2, and k3 which are (1, 3, 1) respectively.

b = 1a1 + 3a2 + 1 × a3

This means that b is a linear combination of a1, a2, and a3 with weights (1, 3, 1) respectively.

The correct answer choice is the last one, your total utility is 61 utils, and the marginal utility of the first slice is 8 utils (22 - 14).

What is marginal utility?

Marginal utility refers to the additional satisfaction or benefit that a consumer derives from consuming one more unit of a good or service. It is the change in total utility resulting from a change in the quantity consumed. It is a way to measure the additional benefit a consumer receives from consuming one more unit of a good or service.

your total utility is 61 utils, and the marginal utility of the first slice is 8 utils (22 - 14). The law of diminishing marginal utility states that as the consumption of a good or service increases, the additional satisfaction or utility from consuming one more unit of the good or service will decline. In this example, as you consume more slices of pizza, the marginal utility of each slice decreases (8 utils for the first slice, 3 utils for the third slice). This is consistent with the law of diminishing marginal utility. Therefore, choice A is incorrect.

Hence, The correct answer choice is the last one, your total utility is 61 utils, and the marginal utility of the first slice is 8 utils (22 - 14).

let the 2 number be a,b

given a+b=8 -- (i)

let the difference of the number is x

so let a-b =x

a-b = x ---(ii)

adding equation (i) and equation (ii) we get

2a = 8 +x

=> a = (8+x)/2

so a = 4+x/2

subtract (ii) from (i) we get:

2b = 8-x

=> b = (8-x)/2

so b = 4-x/2

now the product of both number and their difference is given as a*b*x

=> (4+x/2)*(4-x/2) *x

=> (16 - x²/4)*x

=> 16x - x³/4

let the above value be A

so A = 16x - x³/4

in order to find maximum value of A we have to made dA/dx = 0

=> d(16x - x³/4)dx

=>  16 - 3x²/4

so 16 -  3x²/4 =0

=> 3x²/4 = 16

=> 3x² = 64

=> x² = 64/3

so x = 8/√3

The evaluation of the values of the derivative of the function f, using Lagrange's theorem indicates that the true statements is the following option;

Lagrange Theorem states that there is a point, c between points a and b of an arc such the slope at c is the same as the average slope of the arc between points a and b.

The evaluation of the statements in the question are as follows;

I. If f'(x) exists and is nonzero for all x, then f(1) is not equal to f(0)

If f'(x) exists and the value is non zero, then the slope is not infinite, and the sign of the slope of the function f(x) never changes, such that the as the input (x) value increases the output value decreases, when the slope is negative, or increases when the slope of f(x) is positive, therefore;

The value of f(1) is either larger than or lesser than the value of f(0), which proves that f(1) is not equal to f(0).

II. If f is differentiable for all x and f(-1) = f(1), then there is a number c, such that |c| < 1 and f'(c) = 0

The condition if f is differentiable for all x, then according to Lagrange's, mean value theorem, we get;

When f(|c| < 1) < f(1)

f'(c) < (f(1) - f(-1))/(1 - (-1)) = (f(1) - f(-1))/(2)

f'(c) < (f(1) - f(-1))/(1 - (-1)) = (f(1) - f(-1))/(2) = 0

f'(c) < 0

Similarly, when  f(|c| < 1) > f(1), then, f'(c) < 0

Therefore, f'(c) ≠ 0

III. If f'(c) = 0, then f has a local maximum or minimum at x = c.

The slope of the function f at point x = c is f'(c)

A local maximum or minimum is a point after which the slope of the graph changes sign, and the point at which the slope is zero as the change in the output variable is zero

Therefore, if f'(c) = 0, the graph has a local maximum or minimum at the point f = c
