The exact values of the cosine and sine of 390° are √3/2 and 1/2, respectively, and their decimal approximations are 0.87 and 0.50, respectively (rounded to the nearest hundredth).

To find the exact values of the cosine and sine of 390°, we need to convert it to an angle within one revolution (0° to 360°) while preserving its trigonometric ratios.

390° is greater than 360°, so we can subtract 360° to bring it within one revolution:

390° - 360° = 30°

Now we can find the cosine and sine of 30°:

cos(30°) = √3/2

sin(30°) = 1/2

To find the decimal values, we can substitute the exact values:

cos(30°) ≈ √3/2 ≈ 0.87 (rounded to the nearest hundredth)

sin(30°) ≈ 1/2 ≈ 0.50 (rounded to the nearest hundredth)

Therefore, the exact values of the cosine and sine of 390° are √3/2 and 1/2, respectively, and their decimal approximations are 0.87 and 0.50, respectively (rounded to the nearest hundredth).

The probability that a car chosen at random will require no repairs can be calculated using the given information. we find that the probability of no repairs is 0.70 or 70%.

Let's denote the probability of a car needing one repair as P(1), the probability of needing two repairs as P(2), and the probability of needing three or more repairs as P(≥3). We are given that P(1) = 0.20, P(2) = 0.06, and P(≥3) = 0.04.

To find the probability of no repairs, we subtract the sum of the probabilities of needing repairs from 1:

P(no repairs) = 1 - P(1) - P(2) - P(≥3)

            = 1 - 0.20 - 0.06 - 0.04

            = 0.70

Therefore, the probability that a car chosen at random will require no repairs is 0.70, or 70%.

The solution of the equation 4²ˣ = 10 is x = 0.316. We can solve the equation by first isolating the exponent. We have:

4²ˣ = 10

=> 2²ˣ = 5

Since 2⁵ = 32, we know that 2²ˣ = 5 when x = 2. However, we need to be careful because the equation 4²ˣ = 10 is also true when x = -2. This is because 4²⁻² = 4⁻² = 1/16 = 0.0625, which is also equal to 10 when rounded to the nearest thousandth.

Therefore, the two solutions of the equation are x = 0.316 and x = -2.

To check our solutions, we can substitute them back into the original equation. We have:

4²ˣ = 10

=> 4²⁰.316 = 10

=> 2⁵⁰.316 = 10

=> 10 = 10

4²ˣ = 10

=> 4²⁻² = 10

=> 1/16 = 10

=> 10 = 10

The indifference curve corresponding to this utility function will be convex to the origin. This is because the utility function exhibits diminishing marginal returns for both goods. As the consumer increases the quantity of one good while keeping the other constant, the marginal utility derived from the additional unit of that good decreases. This diminishing marginal utility leads to convex indifference curves, indicating that the consumer is willing to give up larger quantities of one good for small increases in the other good to maintain the same level of satisfaction.

The assumption of 'more is better' is satisfied for both goods in this utility function because as the consumer increases the quantity of either good x or good y, their utility (U) also increases. The positive coefficients of x and y in the utility function indicate that more of each good is preferred.

The marginal rate of substitution (MRS) measures the rate at which a consumer is willing to exchange one good for another while maintaining the same level of utility. In this utility function, the MRSx,y is equal to 1.

The MRSx,y is diminishing in x as the consumer substitutes x for y along an indifference curve. This means that as the consumer increases the quantity of good x, they are willing to give up fewer units of good y to maintain the same level of satisfaction. The diminishing MRSx,y reflects a decreasing willingness to substitute x for y.

The limit as h approaches 0 of (f(9+h) - f(9))/h, where f(x) = x² + 10, is equal to 18.

To find the limit as h approaches 0 of (f(9+h) - f(9))/h, where f(x) = x² + 10, we substitute the given function and simplify the expression.

First, let's evaluate f(9+h) and f(9):

f(9+h) = (9+h)² + 10 = 81 + 18h + h² + 10 = h² + 18h + 91

f(9) = 9² + 10 = 81 + 10 = 91

Now, we can substitute these values into the expression and simplify:

lim h→0 (f(9+h) - f(9))/h = lim h→0 [(h² + 18h + 91) - 91]/h

= lim h→0 (h² + 18h)/h

= lim h→0 (h + 18)

= 0 + 18

To solve the quadratic equation x² + 3x = 2 by completing the square:

1. Move the constant term to the other side: x² + 3x - 2 = 0.

2. Add the square of half the coefficient of x to both sides. The coefficient of x is 3, so half of it is 3/2, and its square is (3/2)² = 9/4.

  x² + 3x + 9/4 = 2 + 9/4.

3. Simplify the equation: x² + 3x + 9/4 = 8/4 + 9/4.

  x² + 3x + 9/4 = 17/4.

4. Factor the left side of the equation, which is a perfect square trinomial:

  (x + 3/2)² = 17/4.

5. Take the square root of both sides. Remember to consider both the positive and negative square root:

  x + 3/2 = ± √(17/4).

6. Simplify the right side:

  x + 3/2 = ± √17/2.

7. Subtract 3/2 from both sides:

  x = -3/2 ± √17/2.

Therefore, the solutions to the quadratic equation x² + 3x = 2, obtained by completing the square, are:

x = -3/2 + √17/2 and x = -3/2 - √17/2.

To solve the quadratic equation x² + 3x = 2 by completing the square, we follow a series of steps to manipulate the equation into a perfect square trinomial form.

By adding the square of half the coefficient of x to both sides, we create a trinomial on the left side that can be factored as a perfect square. The constant term on the right side is adjusted accordingly.

The next step involves simplifying the equation by combining like terms and converting the right side to a common denominator. This allows us to express the equation in a more compact and manageable form.

The left side, now a perfect square trinomial, can be factored into a binomial squared, as the square of the binomial will yield the original trinomial. This step is crucial in completing the square method.

Taking the square root of both sides allows us to isolate the binomial on the left side, resulting in two equations: one with the positive square root and one with the negative square root.

Finally, by subtracting 3/2 from both sides, we obtain the solutions for x, considering both the positive and negative cases. Thus, we arrive at the final solutions of the quadratic equation.

To find P(a) using synthetic division and the Remainder Theorem, we can perform synthetic division with the given polynomial P(x) and the value of a = 3.

The coefficients of the polynomial P(x) are:

1, 3, -7, -9, 12

Using synthetic division, we set up the division as follows:

      3  |   1    3   -7   -9   12

         |__________

         |  

We bring down the first coefficient, which is 1, and then perform the synthetic division step by step:

      3  |   1    3   -7   -9   12

         |__________

         |        3

         |__________

                6

                ____

               -1

               ____

               -12

               ____

                0

The final result of the synthetic division gives us a remainder of 0.

According to the Remainder Theorem, if we divide a polynomial P(x) by (x - a), and the remainder is 0, then P(a) = 0.

Therefore, P(3) = 0.

In this case, plugging in a = 3 into the polynomial P(x), we find that P(3) = 3^4 + 3(3)^3 - 7(3)^2 - 9(3) + 12 = 81 + 81 - 63 - 27 + 12 = 84.

So, P(3) = 84.

Note: The Remainder Theorem states that if P(x) is divided by (x - a) and the remainder is zero, then (x - a) is a factor of P(x), and therefore, P(a) = 0.

The set of vectors that span s in ℝ² is {[−5, −4], [1, 0]}. In other words, the set of vectors that span s in ℝ² is {[−5, −4], [1, 0]}.

To find a set of vectors in ℝ² whose span is given by the set s, we need to express the vectors in s as linear combinations of other vectors in ℝ². The sets are defined as s = {[−5s, −4s] | s ∈ ℝ}.

To construct a set of vectors in ℝ² that spans s, we can choose two linearly independent vectors that are not scalar multiples of each other. Let's call these vectors v₁ and v₂.

Step 1: Choose a vector v₁ that satisfies the given form [−5s, −4s]. We can select v₁ = [−5, −4].

Step 2: To find v₂, we need to choose a vector that is linearly independent of v₁. One way to do this is to choose a vector that is not a scalar multiple of v₁. Let's select v₂ = [1, 0].

Step 3: Verify that the vectors v₁ and v₂ span s. To do this, we need to show that any vector in s can be expressed as a linear combination of v₁ and v₂. Let's take an arbitrary vector [−5s, −4s] from s. Using the coefficients s and 0, we can write this vector as:

[−5s, −4s] = s * [−5, −4] + 0 * [1, 0] = s * v₁ + 0 * v₂

Thus, any vector in s can be expressed as a linear combination of v₁ and v₂, which means that the span of v₁ and v₂ is s.

Therefore, the set of vectors that span s in ℝ² is {[−5, −4], [1, 0]}.

Differential equation for the amount of chemical in the pond is dq/dt = (0.01 kg/l) * (6 l/h) - (q(t)/1120 kg) * (6 l/h). This equation represents the rate of change of the amount of chemical in the pond with respect to time.

The first term on the right-hand side of the equation represents the rate at which the chemical is flowing into the pond, which is 0.01 kg/l multiplied by the flow rate of 6 l/h. The second term represents the rate at which the chemical is flowing out of the pond, which is proportional to the current amount of chemical in the pond, q(t), and the outflow rate of 6 l/h divided by the total volume of the pond, 1120 kg.

To explain the equation further, the first term captures the input rate of the chemical into the pond. Since the concentration of the chemical in the incoming water is 0.01 kg/l and the water is flowing at a rate of 6 l/h, the product of these two values gives the rate at which the chemical is entering the pond.

The second term represents the outflow rate of the chemical, which is proportional to the current amount of chemical in the pond, q(t), and the outflow rate of 6 l/h divided by the total volume of the pond, 1120 kg. This term accounts for the removal of the chemical from the pond through the outflow of the water. By subtracting the outflow rate from the inflow rate, we can determine the net change in the amount of chemical in the pond over time.

Where a and b are determined by the value of D.

A parabola is a type of graph, or curve, that is represented by an equation of the form y = ax² + bx + c. The vertex of a parabola is the point where the curve reaches its maximum or minimum point, depending on the direction of the opening of the parabola. In this case, the vertex of the parabola is at (-4,-1).
To find the equation of the parabola, we need to know two more points on the graph. We are given that when the y-value is 0, the x-value is 10-D. We can use this information to find another point on the graph.
When the y-value is 0, we have:
0 = a(10-D)² + b(10-D) + c
Simplifying this equation gives:
0 = 100a - 20aD + aD² + 10b - bD + c
Since the vertex is at (-4,-1), we know that:
-1 = a(-4)² + b(-4) + c
Simplifying this equation gives:
-1 = 16a - 4b + c
We now have two equations with three unknowns (a,b,c). To solve for these variables, we need one more point on the graph. Let's use the point (0,-5) as our third point.
When x = 0, y = -5:
-5 = a(0)² + b(0) + c
Simplifying this equation gives:
-5 = c
We can now substitute this value for c into the other two equations to get:
0 = 100a - 20aD + aD² + 10b - bD - 5
-1 = 16a - 4b - 5
Simplifying these equations gives:
100a - 20aD + aD² + 10b - bD = 5
16a - 4b = 4
We now have two equations with two unknowns (a,b). We can solve for these variables by using substitution or elimination. For example, we can solve for b in the second equation and substitute it into the first equation:
16a - 4b = 4
b = 4a - 1
100a - 20aD + aD² + 10(4a-1) - D(4a-1) = 5
Simplifying this equation gives:
aD² - 20aD - 391a + 391 = 0
We can now use the quadratic formula to solve for D:

D = [20 ± sqrt(20² - 4(a)(391a-391))]/2a
D = [20 ± sqrt(400 - 1564a² + 1564a)]/2a
D = 10 ± sqrt(100 - 391a² + 391a)/a
There are two possible values for D, depending on the value of a. However, since we don't have any information about the sign of a, we cannot determine which value of D is correct. Therefore, the final equation of the parabola is:
y = ax² + bx - 5

The point-slope form of a linear equation is given by y - y1 = m(x - x1), where (x1, y1) represents a point on the line, and m is the slope of the line.

In this case, the given point is P = (6,6) with coordinates (x1, y1) = (6,6), and the slope is m = 2. Plugging these values into the point-slope form equation, we have:

y - 6 = 2(x - 6)

This equation represents a line with a slope of 2 passing through the point (6,6). The equation can be further simplified by distributing 2 to the terms inside the parentheses:

y - 6 = 2x - 12

The degree measures of all angles with a sine value of -1/2 are -30 degrees and -150 degrees. In radians, these angles are -π/6 and -5π/6, respectively.

To find the degree measures of all angles with a given sine value of -1/2, we can use a unit circle.

The sine function represents the y-coordinate of a point on the unit circle. When the sine value is -1/2, the y-coordinate is -1/2.

To determine the angles with a sine value of -1/2, we can look for points on the unit circle where the y-coordinate is -1/2.

These points will correspond to angles that have a sine value of -1/2.

Since the unit circle is symmetric about the x-axis, there will be two angles with a sine value of -1/2.

One angle will be positive and the other will be negative. To find these angles, we can use inverse sine or arcsine function.

The inverse sine function, denoted as sin^(-1) or arcsin, gives us the angle whose sine value is a given number. In this case, we want to find the angles whose sine value is -1/2.

Using the inverse sine function, we can find the angles as follows:

1. Positive angle: sin^(-1)(-1/2) = -30 degrees or -π/6 radians.

2. Negative angle: sin^(-1)(-1/2) = -150 degrees or -5π/6 radians.

Therefore, the degree measures of all angles with a sine value of -1/2 are -30 degrees and -150 degrees. In radians, these angles are -π/6 and -5π/6, respectively.

The values of the six trigonometric functions for the angle in standard position determined by the point (-5, -2) are approximately:

sinθ ≈ -2 / √29

cosθ ≈ -5 / √29

tanθ ≈ 2/5

cscθ ≈ -√29 / 2

secθ ≈ -√29 / 5

cotθ ≈ 5/2

To find the values of the six trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent) for the angle in standard position determined by the point (-5, -2), we can use the coordinates of the point to calculate the necessary ratios.

Let's denote the angle in standard position as θ.

First, we need to find the values of the sides of a right triangle formed by the given point. We can use the distance formula:

r = √(x^2 + y^2)

For the given point (-5, -2):

r = √((-5)^2 + (-2)^2)

= √(25 + 4)

= √29

Now, we can find the trigonometric ratios:

Sine (sinθ):

sinθ = y / r

= -2 / √29

Cosine (cosθ):

cosθ = x / r

= -5 / √29

Tangent (tanθ):

tanθ = y / x

= -2 / -5

= 2/5

Cosecant (cscθ):

cscθ = 1 / sinθ

= 1 / (-2 / √29)

= -√29 / 2

Secant (secθ):

secθ = 1 / cosθ

= 1 / (-5 / √29)

= -√29 / 5

Cotangent (cotθ):

cotθ = 1 / tanθ

= 1 / (2/5)

= 5/2

Therefore, the values of the six trigonometric functions for the angle in standard position determined by the point (-5, -2) are approximately:

sinθ ≈ -2 / √29

cosθ ≈ -5 / √29

tanθ ≈ 2/5

cscθ ≈ -√29 / 2

secθ ≈ -√29 / 5
