Yes, Tanner has enough spray paint for his arrow.

What is an Area?

The amount of space occupied by a flat (2-D) surface or an object's shape is known as its area. A planar figure's area is the area that its perimeter encloses. The quantity of unit squares that completely encircle the surface of a closed figure is its area. Square measurements for area include cm2 and m2.

Given : paint available in can = 12 ft²

We know that the arrow is comprised of a triangle and a rectangle.

So, the area of given arrow = area of rectangle + area of triangle

Now, area of triangle = 1/2 ×base × height

                                    = 1/2 × 3 × (6 - 5 1/3)

                                    = 3/2 × ( 6 - 16/3)

                                    = 3/2 × ( 18-16)/3

                                    = 3/2 × 2/3

                                    = 1 ft²

Similarly, area of rectangle =  length × breadth

                                             = 5 1/3 × 2

                                             = 16/3 × 2

                                             = 32/3 ft²

Hence, area of arrow = area of triangle +area of rectangle

                                    = 1 + 32/3

                                    = 35/3 ft²

                                    = 11.67 ft²

So, he has sufficient paint to cover the arrow.

The associationA \mapsto g_{A} is an isomorphism between the space of m x n matrices with coefficients in K and the space of bilinear forms in Km x K​​​​​​​n.

The associationA \mapsto g_{A} is an isomorphism between the space of m x n matrices with coefficients in K and the space of bilinear forms in Km x K​​​​​​​n if it satisfies the following conditions:

1. It is a one-to-one correspondence, meaning that for every matrix A there is a unique bilinear form g_{A} and vice versa.
2. It preserves the structure of the spaces, meaning that the operations of addition and scalar multiplication are preserved.

To show that the associationA \mapsto g_{A} is a one-to-one correspondence, we can start by assuming that g_{A} = g_{B} for two matrices A and B. Then, for any vectors u \in Km and v \in K​​​​​​​n, we have:

g_{A}(u,v) = g_{B}(u,v)

A \cdot (u \otimes v) = B \cdot (u \otimes v)

(A - B) \cdot (u \otimes v) = 0

Since this is true for all u and v, we can conclude that A - B = 0, or A = B. This means that the associationA \mapsto g_{A} is a one-to-one correspondence.

To show that the associationA \mapsto g_{A} preserves the structure of the spaces, we can start by considering the addition of two matrices A and B and the scalar multiplication of a matrix A by a scalar c. Then, for any vectors u \in Km and v \in K​​​​​​​n, we have:

g_{A + B}(u,v) = (A + B) \cdot (u \otimes v) = A \cdot (u \otimes v) + B \cdot (u \otimes v) = g_{A}(u,v) + g_{B}(u,v)

g_{cA}(u,v) = (cA) \cdot (u \otimes v) = c(A \cdot (u \otimes v)) = c g_{A}(u,v)

This means that the associationA \mapsto g_{A} preserves the operations of addition and scalar multiplication.

Therefore, the associationA \mapsto g_{A} is an isomorphism between the space of m x n matrices with coefficients in K and the space of bilinear forms in Km x K​​​​​​​n.

Hello there! To find f ∘ g, g ∘ f, and g ∘ g, let's first recall the definition of function composition: given two functions f and g, their composition f ∘ g is defined as the function that results from applying g to the result of applying f to its argument. Specifically, for a given input x, we can express the composition f ∘ g as follows: (f ∘ g)(x) = f(g(x)).

Given f(x) = x4 and g(x) = 1/x, we can find each composition as follows:

(a) f ∘ g = f(g(x)) = f(1/x) = (1/x)4

(b) g ∘ f = g(f(x)) = g(x4) = 1/(x4)

To find the value of k for which the matrix A has one eigenvalue of multiplicity 2, we can use the characteristic equation of the matrix. The characteristic equation is det(A-λI)=0. For a given matrix, this equation will yield a polynomial equation of degree equal to the dimension of the matrix.

In this case, the equation is (λ+4)(λ-2) = 0. Solving this equation gives us two distinct eigenvalues of λ= -4 and λ=2. This means that for any value of k, the matrix A will have two distinct eigenvalues, and thus cannot have one eigenvalue of multiplicity 2. Therefore, the matrix A cannot have one eigenvalue of multiplicity 2 no matter what value of k is used.

The mechanic must mix 12 gallons of a 40% antifreeze solution with 4 gallons of an 80% antifreeze solution to create 16 gallons of a 50% antifreeze solution.

To find out how much of a 40% antifreeze solution must be mixed with an 80% antifreeze solution to create 16 gallons of a 50% antifreeze solution, we can use the following equation:

40% x + 80% y = 50% (16)

Where x is the amount of 40% antifreeze solution and y is the amount of 80% antifreeze solution.

We can also use the fact that the total amount of solution must equal 16 gallons:

x + y = 16

Now we can solve for one variable in terms of the other. Let's solve for x in the second equation:

x = 16 - y

And substitute this value of x into the first equation:

40% (16 - y) + 80% y = 50% (16)

Simplifying:

[tex]6.4 - 0.4y + 0.8y = 8[/tex]

The probability that a hotel room costs $227 or more per night in New York City is 0.3406.

It is a branch of mathematics that deals with the occurrence of a random event.

Lets standardize the value of $227 per night using the formula:

z = (x - μ) / σ

where x is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation of the distribution. Substituting the given values, we get:

z = (227 - 205) / 54

z = 0.4074

We need to find the probability that a hotel room costs $227 or more per night, which is equivalent to finding the probability that a standardized value is greater than or equal to 0.4074.

Using a standard normal table, we find:

P(Z ≥ 0.4074) = 1 - P(Z < 0.4074)

P(Z ≥ 0.4074) = 1 - 0.6594

P(Z ≥ 0.4074) = 0.3406

To prove that T is a linear transformation, we need to show that T(c~u + ~v) = cT(~u) + T(~v) for any scalar c and any vectors ~u and ~v in R2.

Let ~u = (u1, u2) and ~v = (v1, v2) be two vectors in R2 and let c be any scalar. Then,

T(c~u + ~v) = T(cu1 + v1, cu2 + v2) = (3(cu1 + v1) - 2(cu2 + v2), 2(cu2 + v2))

= (3cu1 + 3v1 - 2cu2 - 2v2, 2cu2 + 2v2)

= (3cu1 - 2cu2, 2cu2) + (3v1 - 2v2, 2v2)

= c(3u1 - 2u2, 2u2) + (3v1 - 2v2, 2v2)

= cT(~u) + T(~v)

Therefore, T is a linear transformation.

To find the standard matrix A of T, we can use the fact that T(~e1) and T(~e2) are the first and second columns of A, respectively, where ~e1 = (1, 0) and ~e2 = (0, 1) are the standard basis vectors of R2.

T(~e1) = T(1, 0) = (3(1) - 2(0), 2(0)) = (3, 0)

T(~e2) = T(0, 1) = (3(0) - 2(1), 2(1)) = (-2, 2)

Therefore, the standard matrix A of T is:

A = [ 3  -2 ]
     [ 0   2 ]

To determine if T is one-to-one, we can use the fact that a linear transformation is one-to-one if and only if its standard matrix A has linearly independent columns. In this case, the columns of A are linearly independent because they are not scalar multiples of each other. Therefore, T is one-to-one. Alternatively, we can use the fact that a linear transformation is one-to-one if and only if its standard matrix A has a nonzero determinant. In this case, the determinant of A is (3)(2) - (0)(-2) = 6, which is nonzero. Therefore, T is one-to-one.

The equation that represents a linear function is:

y equals one half times x minus 5

This is a linear equation because it has a constant rate of change, or slope, of one half. This means that for every increase of 1 in x, y will increase by 1/2. The equation is also in the standard form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

The other equations are not linear functions:

x = 3 is a vertical line, which is not a function because it fails the vertical line test.

y equals three fourths times x squared is a quadratic function because it includes an x-squared term.

3x − 6 = 4 is a linear equation, but it is not in the standard form of y = mx + b. It can be rearranged to y = (3/1)x - 2, which is a linear equation in slope-intercept form.

C. The account earns 1.2% in yearly interest.

Step-by-step explanation:

The expression 750(1+0.012) represents the amount of money in a savings account earning yearly interest after t years, where t is the number of years since the account was opened.

The expression (1+0.012) represents the interest rate as a decimal. The value 0.012 represents 1.2% in decimal form, which is the yearly interest rate earned by the account.

Therefore, (1+0.012) represents the account's yearly interest rate as a decimal, which is 1.2%.
