Step-by-step explanation:

The total amount spent is $372, and this can be divided by 20. Each costume would cost $18.60.

Answer:

x = 35

Important things to know:

1. A + (x + 110) will equal 180 degrees

2. The interior angles of a triangle will equal 180 degrees.

With these two pieces of knowledge, you can substitute the value of A as "180 - (x+110)" because A = 180-(x+110)

2/3 is the scale factor of the given graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Let EFGH is a quadrilateral.

The vertices of quadrilateral are E(-2, -1), F(1, 2), G(6, 0) and H(2, -2)

Now  the quadrilateral E'F'G'H' has vertices E'(-3, -3/2), F'(3/2, 3), G'(9, 0) and H'(3, -3)

We have to find the scale factor.

A scale factor is defined as the ratio between the scale of a given original object and a new object,

(-2, -1) is original coordinate

'(-3, -3/2) is transformed coordinate.

Scale factor=(-2/-3, -1/(-3/2)

Scale factor=2/3

Hence, 2/3 is the scale factor of the given graph.

Step-by-step explanation:

complex roots always occur in pairs.

roots are 1,2-2i,2+2i

P(x)=a(x-a)(x-b)(x-c)

P(x)=1(x-1)[x-(2-2i)][x-(2+2i)]

Answer:

x ≈ 75.2

Step-by-step explanation:

using the tangent ratio in the right triangle

tan62° = \(\frac{opposite}{adjacent}\) = \(\frac{x}{40}\) ( multiply both sides by 40 )

40 × tan62° = x , then

x ≈ 75.2 ( to the nearest tenth )

Using Green's theorem the line integral H C(4x2 y3)dx+ ( x3 + y2)dy is 70.6858.

Step: 1

Given

\(\int\limi {4x2 - y3} \, dx + (x3+y2) dy\)

Formula for Greens theorem

δQ/δx = 3x2

Explanation:

partial derivative w.r.t x i . e y is constant

partial derivative w.r.t y i. e x is constant

power rule of derivative is

d/dx Xn = nXⁿ⁻¹

Step: 2

\(\int\limits\int\li {dQ/dy + dP/dx dA} \, dx = \int \int {3(x2+y2)} \, dx\)

Explanation:

in polar coordinates x2 + y2 = r2 and dA = radθ

Step: 3

given

C1 = r1 = 2

C2 = r2 = 1

the limits for r is 1 ≤ r ≤ 2

since it is a circle the limits for θ

0 ≤ θ ≤ 2π

Explanation: Please refer to solution,

now integrate w.rt θ

= 45/4[θ] 2π

= 45/4[2π - 0]

= 45/4(2π)

= 45/2(π)

= 45π/2 ≈ 70.6858.

by greens theorem,

Then combine like terms:

Check the picture below.

The lengths of the other two sides is 6 inches each.

The perimeter of any figure is sum of all the sides of the figure.

Here, we are given that the area of a triangle is 18 inches. Also, in the figure, we can see that the 3 sides of the triangle are-

6 inches, s inches and s inches.

Therefore, the perimeter of the given triangle will be-

Perimeter = 6 + s + s

⇒ 18 = 6 + s + s

Thus, the equation to find the lengths of the two sides is-

18 = 6 + 2s

18 - 6 = 2s

12 = 2s

2s = 12

s = 12/ 2

s = 6

Thus, the lengths of the other two sides is 6 inches.

A statement which best describes one of these transformations is that: A. triangle 1 is rotated to result in triangle 2.

In Mathematics, there are four (4) main types of transformation and these include the following:

In Mathematics, a rotation simply refers to a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

Since triangle 2 has identical (similar) side lengths and angle measures, but is rotated and triangles 1 and 4 are identical, we can logically deduce that triangle 1 underwent a rotation to produce triangle 2.

This one's a special case of a right angled triangle with sides (3, 4, and 5 units)

Answer: x = 17

y = 102 degrees

Explanation:

The opposite sides of a parallelogram are equal and parallel. From the information given,

opposite side of x is 17. Thus,

x = 17

Also, the sum of the consecutive angles are in a parallelogram is 180 degrees. 78 and y are consecutive angles. This means that

78 + y = 180

y = 180 - 78

y = 102 degrees

Answer:

x = −4

Step-by-step explanation:

Add x to both sides of the equation. x + 4 + x = − 4 Add x and x . 2 x + 4 = −4

Subtract 4 from both sides of the equation. 2 x = −4 − 4 Subtract 4 from - 4. 2x = −8

Divide each term in 2x = −8 by 2. 2x/2 = −8/2

Cancel the common factor. 2x/ 2 = −8/2 Divide x by  1.  x = −8/2

Divide  −8 by 2. x = −4

Answer: 7.2x = 4,000.

Step-by-step explanation:

If cost is represented by C(x) = 2.2x + 4,000 and revenues are represented by R(x) = 9.4x, the break-even point occurs when the cost equals the revenue, or C(x) = R(x). We can substitute the given equations into this expression and solve for x:

2.2x + 4,000 = 9.4x

7.2x = 4,000

x = 4,000 / 7.2

Therefore, the equation that could be used to find the break-even point is 7.2x = 4,000.

Step-by-step explanation:

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.

Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.

We have:

z₁ = 7(cos(577°) + i sin(577°))

Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.

From the given information, we have:

z₂ = 21(cos(-7°) + i sin(-77°))

To find the quotient, we divide z₁ by z₂:

z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]

Substituting the given values, we have:

z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]

= (7/21) * [cos(584°) + i sin(584°)]

The quotient of z₁ by z₂ in trigonometric form is:

7/21 * (cos(584°) + i sin(584°))

Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Given that,

David plays baseball for 3 months, and each month he plays 18 times.

Also, David plays soccer for 3 months, and each month he plays 15 times.

In 3 months, David plays baseball = 18 x 3 = 54

Also, in 3 months, David plays soccer = 15 x 3 = 45

The more number of times David plays baseball than soccer

= 54 - 45

Answer:

The amount of safety inventory of cell phones best  buy should carry is $465.277

Step-by-step explanation:

Solution

We recall that:

The weekly demand for cell phones=  300 per week

The Standard Deviation = 200 per week

The lead time or number of weeks = 2 weeks (14 days)

Thus,

Z = 95%

= 1.645

Now,

The standard deviation of lead time = Standard deviation√ *√ lead time

Which is

= 200 * √ (2) =2.82.843

So,

The safety inventory = Z * Standard deviation of the lead time

= 1.645 * 2.82.843

$465.277
