V = 700e^(-0.2t)

The man has 7 shirts in total, so he can take 3 of those shirts on his 3-day trip without repetition. This means that he can make 7 different combinations of shirts, since each shirt has only one choice. For example, he could take shirts A, B, and C; or he could take shirts D, E, and F; or he could take shirts G, A, and B. In total, he has 7 different combinations of shirts to choose from.
The number of combinations of shirts that the man can take without repetition can be found using the formula for combinations, which is:
C(n, r) = n! / (r! * (n-r)!)

In this case, n = 7 (the total number of shirts) and r = 3 (the number of shirts he will take with him).

Plugging in these values into the formula, we get:

C(7, 3) = 7! / (3! * (7-3)!)

C(7, 3) = 7! / (3! * 4!)

C(7, 3) = 5040 / (6 * 24)

C(7, 3) = 5040 / 144

C(7, 3) = 35

Therefore, the man can take 35 different combinations of shirts without repetition.

Answer: J. A = 12 (4⋅6).

Step-by-step explanation:

Answer: J. A = 12 (4⋅6).

This equation can be used to find the area of the triangle in the diagram because it uses the formula for the area of a triangle, which is A = 1/2 * b * h, where b is the base and h is the height. Since the triangle in the diagram has a base of 4 and a height of 6, the equation A = 12 (4⋅6) can be used to find the area.

Answer:

The diagram is not provided, so it's difficult to determine the exact dimensions of the triangle and parallelogram. However, we can make some general observations to determine which equation can be used to find the area of the triangle.

First, we know that the area of a triangle is given by the formula:

A = 1/2 * base * height

We also know that the area of a parallelogram is given by the formula:

A = base * height

In the diagram, the triangle can be formed into a parallelogram by taking one of its sides and using it as the base of the parallelogram. The height of the parallelogram is the same as the height of the triangle.

Based on these observations, we can conclude that the equation that can be used to find the area of the triangle is:

A = 1/2 * base * height

where the base is one of the sides of the triangle, and the height is the height of the parallelogram (which is the same as the height of the triangle).

None of the answer choices provided match this equation, so the correct answer is not given.

The equation of the circle centered at (-4,3) with radius 3 is (x + 4)^2 + (y - 3)^2 = 9. Simplifying this equation means to simplify the terms in the equation by using the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse.

In this equation, the hypotenuse is the radius, which is 3, and the sides are (x + 4) and (y - 3). Substituting the values into the Pythagorean Theorem, we get (x + 4)^2 + (y-3)^2 = 9, which is the equation of the circle centered at (-4,3) with radius 3. This equation can be simplified further by factoring the terms, which yields (x + 4) (x + 4) + (y - 3) (y - 3) = 9. This is the fully simplified equation of the circle.

To prove that C is a field, we need to show that it satisfies the following 11 axioms of a field:

C is closed under addition: For all a, b ∈ C, a + b ∈ C.

C is closed under multiplication: For all a, b ∈ C, ab ∈ C.

C is associative under addition: For all a, b, c ∈ C, (a + b) + c = a + (b + c).

C is associative under multiplication: For all a, b, c ∈ C, (ab)c = a(bc).

C has an additive identity: There exists 0 ∈ C such that for all a ∈ C, a + 0 = a.

C has a multiplicative identity: There exists 1 ∈ C such that for all a ∈ C, a1 = a.

C has additive inverses: For all a ∈ C, there exists b ∈ C such that a + b = 0.

C has multiplicative inverses: For all a ≠ 0 ∈ C, there exists b ∈ C such that ab = 1.

C is commutative under addition: For all a, b ∈ C, a + b = b + a.

C is commutative under multiplication: For all a, b ∈ C, ab = ba.

Multiplication distributes over addition: For all a, b, c ∈ C, a(b + c) = ab + ac.

Proofs of the 11 axioms:

To show that C is closed under addition, we can use the fact that the sum of two complex numbers is also a complex number. That is, for any a, b ∈ C, a + b = (a + bi) + (b + di)i, where i is the imaginary unit. This is clearly a complex number, so C is closed under addition.

To show that C is closed under multiplication, we can use the fact that the product of two complex numbers is also a complex number. That is, for any a, b ∈ C, ab = (a + bi)(b + di) = (ab - bd) + (ad + bc)i, which is also clearly a complex number, so C is closed under multiplication.

To show that C is associative under addition, we can use the associative property of addition for real numbers. That is, for any a, b, c ∈ C, (a + b) + c = a + (b + c).

To show that C is associative under multiplication, we can use the associative property of multiplication for real numbers. That is, for any a, b, c ∈ C, (ab)c = a(bc).

To show that C has an additive identity, we can use the fact that the real number 0 is also a complex number, and that for any a ∈ C, a + 0 = a.

To show that C has a multiplicative identity, we can use the fact that the real number 1 is also a complex number, and that for any a ∈ C, a1 = a.

To show that C has additive inverses, we can use the fact that for any a ∈ C, there exists a complex number -a such that a + (-a) = 0. This is because the real numbers have additive inverses, and the imaginary unit i has an additive inverse -i.

To show that C has multiplicative inverses, we can use the fact that for any a ≠ 0 ∈ C, there exists a complex number 1/a such that a(1/a) =

The equation of the parabola in the form y = a(x - r)(x - s) is y = -2(x + 2)(x + 8).

To determine the equation of the parabola in the form y = a(x - r)(x - s), we need to find the values of a, r, and s. We are given the x-intercepts and the vertex, so we can use this information to find these values.

The x-intercepts are -2 and -8, so we know that r=-2 and s=-8. The vertex is (-5,-18), so we can plug these values into the equation and solve for a:

y = a(x - r)(x - s)
-18 = a(-5 + 2)(-5 + 8)
-18 = a(-3)(3)
-18 = 9a
a = -2

Answer:

c(t) = $85 × (1.09)^t

Step-by-step explanation:

Assuming that the inflation rate remains constant at 9% per year, the cost of the athletic shoes after t years can be determined by multiplying the original cost by the inflation factor for t years, which is given by (1 + 0.09)^t, or 1.09^t. Therefore, the algebraic rule to determine the cost, c(t), of the shoes after t years is:

c(t) = $85 × 1.09^t

Simplifying the expression, we get:

c(t) = $85 × (1.09)^t

where t is the number of years after the original purchase.

Quinn has 6 dimes and 15 quarters in his pocket.

Let's use a system of two equations to represent the given information:

d + q = 21      (1)   // The number of dimes and quarters adds up to 21

10d + 25q = 435 (2)   // The total value of the coins in cents is 435

where d represents the number of dimes and q represents the number of quarters.

We can use equation (1) to solve for d in terms of q:

d = 21 - q

Substituting this expression for d into equation (2), we get:

10(21 - q) + 25q = 435

210 - 10q + 25q = 435

15q = 225

q = 15

This equation is true, so the equation is true for n = k+1. Therefore, by induction, the equation is true for all n. To demonstrate the equations using induction, we need to follow three steps: the base case, the induction hypothesis, and the induction step.

1) P(n) : 2 + 4 + 6 + ⋯+ 2n= n(n+ 1), ∀ n∈ℕ.

Base case: For n = 1, the equation becomes 2 = 1(1+1), which is true.

Induction hypothesis: Assume the equation is true for n = k, that is, 2 + 4 + 6 + ⋯+ 2k= k(k+ 1).

Induction step: We need to show that the equation is also true for n = k+1. That is, 2 + 4 + 6 + ⋯+ 2k + 2(k+1)= (k+1)(k+2).

Using the induction hypothesis, we can substitute k(k+1) for 2 + 4 + 6 + ⋯+ 2k:

k(k+1) + 2(k+1) = (k+1)(k+2)

Distributing the (k+1) on the right side of the equation gives us:

k(k+1) + 2(k+1) = k(k+1) + 2(k+1)

This equation is true, so the equation is true for n = k+1. Therefore, by induction, the equation is true for all n.

2) ∑i^2= n(n+1)(2n+1)/6, ∀ n∈ℕ.

Base case: For n = 1, the equation becomes 1^2 = 1(1+1)(2(1)+1)/6, which simplifies to 1 = 1, which is true.

Induction hypothesis: Assume the equation is true for n = k, that is, ∑i^2= k(k+1)(2k+1)/6.

Induction step: We need to show that the equation is also true for n = k+1. That is, ∑i^2 + (k+1)^2 = (k+1)(k+2)(2(k+1)+1)/6.

Using the induction hypothesis, we can substitute k(k+1)(2k+1)/6 for ∑i^2:

k(k+1)(2k+1)/6 + (k+1)^2 = (k+1)(k+2)(2(k+1)+1)/6

Multiplying both sides of the equation by 6 gives us:

k(k+1)(2k+1) + 6(k+1)^2 = (k+1)(k+2)(2(k+1)+1)

Distributing the (k+1) on both sides of the equation gives us:

k(k+1)(2k+1) + 6(k+1)^2 = k(k+1)(k+2)(2k+3)

This equation is true, so the equation is true for n = k+1. Therefore, by induction, the equation is true for all n.

Answer:

Point D is the solution to the system of equations.

Step-by-step explanation:

When asked for a solution involving 2 equations, the goal is to find a point (x,y) that would be a solution to both equations.  Any point on a line that is defined by an equation is a solution to that equation.  For an equation of y = 2x + 2, possible solutions are (1,4), (2,6), (5,12) etc.  These points all lie on the line formed by that equation.  There are an infinite number of possible solutions.  If a second eqaution is added, there is now a constraint on the possible answers.  The goal is to find a point that satisfies both equations.

If a seond equation of y = 1x + 3 were matced with y=2x+2, both are straight lines, but with different slopes.  So they will intersect at some point.  One may either solve mathematically using substitution, or by graphing, as was done here.  

Matematically:

y = 2x + 2

y = 1x + 3

Rearrange either equation to isolate a variable, x or y.  These are already isolated (since I made them up) so go to the next step of substituting one expression of y into the other:

y = 1x + 3

2x + 2 = 1x + 3

x = 1

Now use this value of x to find y:

y = 2x + 2

y = 2*(1) + 2

y = 4

The point these two lines intersect is (1,4) and is the "solution" to this series of equations.
