Answer:

y = - 3x - 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 3 , then

y = - 3x + c

the line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = - 3x - 3 ← equation of line of reflection

A relative clause, also known as an adjective clause, is a type of dependent clause that serves to describe a noun in a sentence. Even though it is made up of several words rather than just one, it functions as an adjective. All of the words in an adjective clause work together to modify the noun or pronoun.

The adjective clauses in a sentence are dependent clauses, which are a group of words that consist of a subject and a verb, but it is not a complete sentence that can stand alone. They usually begin with a relative pronoun, but it can be omitted, and they come after the noun they describe.

Answer: 4x+2x+12x+9x+10x

Step-by-step explanation: The simplified expression is 37x. I didn't put an equal sign because that makes it an equation. The perimeter is the sum of all sides. All sides are given except one which can be solved using 12x because it is 2x less than that value or 10x.

The required critical points of f is (0, 0) and the function f does not have a local maximum nor local minimum.

The critical points of a function f are the points in the domain where the partial derivatives of f are equal to 0 or are undefined. To find the critical points of f, we can find the partial derivatives of f with respect to x and y, and set them equal to 0:

df/dx = -2x

df/dy = 2y

Setting df/dx equal to 0, we have:

-2x = 0

So, x = 0.

Setting df/dy equal to 0, we have:

2y = 0

So, y = 0.

Thus, the only critical point of f is (0, 0).

To show that f does not have any local maximums nor any local minimums at the critical point (0, 0), we can check the second partial derivatives of f at this point:

d²f/dx² = -2

d²f/dy² = 2

d²f/dxdy = 0

At (0, 0), d²f/dx² is negative and d²f/dy² is positive, which indicates that f is a saddle point at (0, 0). This means that f does not have a local maximum nor a local minimum at (0, 0).

The equilibrium point for the market is reached when the number of units is 955 and the price is $82.8.

What is meant by the equilibrium of supply and demand?

The only price at which consumer and producer desires coincide is equilibrium, or when the quantity of the good that consumers want to buy equals the quantity that producers want to sell.

The equilibrium quantity is the amount that both parties seek equally. Any other price causes the market to be out of equilibrium since the amount requested does not match the quantity supplied. On a graph, the equilibrium is represented by the intersection of the supply and demand curves (S and D).

Given,

 Demand equation for a cordless screwdriver: p = 91.4 -0.009x

Supply equation for the cordless screwdriver:  p=6.4+0.08x

where,

  p = price in dollars

 x = number of units

The equilibrium point for this market is

 demand = supply

91.4 -0.009x = 6.4+0.08x

 85 = 0.089x

x = 955 units

Price = 6.4 + 0.08 * 955 = $82.8

The equilibrium point for the market is reached when the number of units is 955 and the price is $82.8.

Above that the statement indicates just simple interest equals $157.92.

With only the coordination mechanism and a fixed interest rate, simple yearly interest is interest connected to borrowing. Compounding, wherein borrowers are obligated to pay tax on the principal as well as interest that rises over a number of pay periods, is not included. Simple interest is calculated by multiplying the original by calendar, rate of return and time period.

Due to it,

P = $1305.17

R = 11/10%

T = 11 months

Now, Simple Interest = P*R*T/100

Simple Interest = 1305.17 * 1.1 * 11/100

Simple Interest = 157.92

Answer:

Step-by-step explanation:

Given that cos(60°) = 1/2, we can use trigonometric identities to find the sine, cosine, and tangent of 30°:

Sine of 30°:

sin(30°) = √[1 - cos^2(30°)] = √[1 - (cos(60°)/2)^2] = √[1 - 1/4] = √3/2.

Cosine of 30°:

cos(30°) = √[1 - sin^2(30°)] = √[1 - (√3/2)^2] = √[1 - 3/4] = √1/4.

Tangent of 30°:

tan(30°) = sin(30°) / cos(30°) = (√3/2) / (√1/4) = √3.

So, the sine of 30° is √3/2, the cosine of 30° is √1/4, and the tangent of 30° is √3.

The following statements is true: (c) if a trapezoid is also a kite, then it must be a parallelogram and others (a),(b) &(d) are false.

The following is a list of true and false statements regarding the relationship between kites, parallelograms, rhombi, and trapezoids:

(a) False. If a kite is also a parallelogram, it does not necessarily mean that it is a rhombus. A rhombus is a type of parallelogram with equal sides, while a kite is a specific type of quadrilateral with two pairs of equal-length sides.

(b) False. If a trapezoid is also a parallelogram, it does not necessarily mean that it is a rhombus. A rhombus is a type of parallelogram with equal sides, while a trapezoid is a type of quadrilateral with exactly one pair of parallel sides.

(c) True. If a trapezoid is also a kite, then it must be a parallelogram. A kite is a specific type of quadrilateral with two pairs of equal-length sides, which automatically makes it a parallelogram.

(d) False. If a rhombus is also a trapezoid, it does not necessarily mean that it is a kite. A kite is a specific type of quadrilateral with two pairs of equal-length sides, while a rhombus is a type of parallelogram with equal sides.

the equation of the line tangent to the curve y at x = 3 is y = 36x - 102.  The slope of the tangent line to the curve y at x = 3 is 36.

The equation of the line tangent to the curve y at x = 3 can be written using the point-slope form of a line, which is:

y - y1 = m(x - x1)

where m is the slope of the line, (x1, y1) is a point on the line, and m and (x1, y1) are known. In this case, m = 36 and (x1, y1) = (3, y). Substituting these values into the equation above, we get:

y - y = 36(x - 3)

y = 36x - 102

As a result, the vector x whose coordinate vector relative to the basis B is [5 4] in R² is (45/11, -54/11).

A vector is a matrix that has only one row or one column. A row vector is a matrix with only one row. Example Because it only contains one row, the matrix is a row vector. A column vector is a matrix with only one column. A vector is a quantity linear array. A matrix is a two-dimensional array of values. Tensors are three-dimensional and higher-dimensional arrays that exist. A matrix can be thought of as a sequence of column vectors, but it can also be thought of as a sequence of row vectors; both interpretations are valid.

Here,

To find the vector x in R² whose coordinate vector relative to the basis B is [5 4], we need to express the vector x as a linear combination of the basis vectors [5 -6] and [-7 2].

Using the formula [x]_B = [5 4] = a[5 -6] + b[-7 2], where a and b are scalars, we can solve for a and b:

5 = 5a - 6b

4 = -7a + 2b

Solving for a and b using the system of equations:

a = 9/11

b = 14/11

So, x = 9/11 [5 -6] + 14/11 [-7 2] = (45/11, -54/11).

So, the vector x whose coordinate vector relative to the basis B is [5 4] is (45/11, -54/11) in R².

Answer:

$12,581.53

Step-by-step explanation:

The balance of an account after having interest compounded annually can be represented using the equation:

[tex]A = P(1 + r)^{t}[/tex]

where [tex]A[/tex] is the final balance, [tex]P[/tex] is the principal (starting amount), [tex]r[/tex] is the rate of interest, and [tex]t[/tex] is the number of years that interest is applied.

We can plug the given values into this equation and solve for [tex]A[/tex].

[tex]P = \$10,000[/tex]     [tex]r = 4.7\%[/tex]     [tex]t = 5[/tex]

[tex]A = 10,000(1 + 4.7\%)^{5}[/tex]

[tex]A \approx \$12,581.53[/tex]

So, Sally's balance in an account that had $10,000 before being compounded for 5 years at an interest rate of 4.7% is $12,581.53.
