Answer:

x=400-

+6y/2

Step-by-step explanation:

The equation starts as: 2x+6y=400

Now we have to get x by itself:

2x+6y=400

    -6y  -6y

2x=400+6y

÷2  ÷2   ÷2

x=(400÷2)+(6y÷2)

x=200+3y

(Note: This problem is asking for the "unsimplified version" so the answer is 400+6y/2)

The weighted average cost of capital for Android Corp. is 12.41%.

First, calculate the weight of each source of capital:

- Common stock: $50 million / ($50 million + $27 million) = 0.65
- Debt: $27 million / ($50 million + $27 million) = 0.35

Next, calculate the cost of each source of capital:
- Common stock: 18%
- Debt: 3%

Finally, calculate the weighted average cost of capital using the following formula:

WACC = (weight of common stock x cost of common stock) + (weight of debt x cost of debt)
WACC = (0.65 x 0.18) + (0.35 x 0.03)
WACC = 0.117 + 0.0105
WACC = 0.1275 or 12.41%

Hence the wieght  weighted average cost of capital for Android Corp. is 12.41%.

Given an angle that is positive, less than 360°, and coterminal with 395° is 35°.

Subtract 360° from 395°.

We know that 1 revolution is equal to 360°.

Therefore, a positive angle that is less than 360° and coterminal with 395° is 35°.

When an angle is less than 360° and shares the same terminal side with another angle that is less than 360°, then the angle is referred to as a coterminal angle.

In other words, the two angles have the same initial side and terminal side but can be either positive or negative.

Answer:

a) The piece of pizza she should choose is BE

b) The length of the cheese in her piece of the crust is approximately 20.07 inches

Step-by-step explanation:

The given diameter of the pizza, AE = 20 in.

The measure of the arc AB, \(m\widehat{AB}\) = ∠ACB = 65°

The measure of the arc DE, \(m\widehat{DE}\) = ∠DCE = 110°

Given that AE is the diameter of the circular pizza, we have;

\(m\widehat{BE}\) = ∠BCE = 180° - ∠ACB = 180° - 65° = 115°

Similarly;

∠ACD = 180° - ∠DCE = 180° - 110° = 70°

a) The biggest piece of pizza is the piece with the largest angle which is the  piece formed by arc BE, \(m\widehat{BE}\) = 115°

The piece of pizza she should choose is the piece, BE

b) Arc length = (Arc angle)/360 × (Circumference of the circle)

The circumference of the circular pizza, C = π × Diameter = π × length \(\overline {AE}\)

∴ C = π × 20 in.

The arc length of the arc BE = 115/360 × π × 20 = 115·π/18 ≈ 20.07

The length of the cheese in her piece of the crust, l = The arc length of the arc BE ≈ 20.07 inches.

-6, 14, -26, 10x -4, -8x + -2x - 6

Step-by-step explanation:

So F(x) is setting that the values before the lines are equal to x and should be applied to the problem. Dont forget PEMDAS with these tho, they'll try to trick u like that.

So for the first one, f(0) you plug 0 where the x's are.

1.) 8(0)^2 +2(0) -6

0 + 0 - 6 = -6

2.) 8(2) +2(2) - 6

16+ 4-6= 20 - 6= 14

3.) 8(-2) + 2(-2) -6

-16 + -4 -6 = -26

On the ones where they leave the x there, you just have to leave the x. But don't forget distribution tho.

4.) 8(x+1) +2(x+1) -6

8x +8 + 2x + 2 -6

10x +10 -6 = 10x -4

5.) 8(-x) + 2(-x) -6

-8x + -2x -6

Step-by-step explanation:

the given function is f(x) = 8x² + 2x -6

f(0) = 8(0)² + 2(0) -6 = -6

f(2) = 8 (2)² + 2 (2) - 6 = 30

f(-2) = 8 (-2)² + 2 (-2) - 6 = 22

f (x+1) = 8(x+1)² + 2 (x+1) -6

= 8(x² +2x +1 ) + 2x -4

8x² + 16x +8 +2x -4 = 8x² + 18x + 4

f(-x) = 8(-x)² + 2 (-x) - 6

= 8x² -2x -6

The length of the crease is √10cm

To determine the length of the crease, we have;

Let the equal sides of the black triangle  = x = length of the fold

From the information given, we have the area of the square is 15cm²

Then, we have;

The area of this triangle = (1/2)x²   = x²/2

Substitute the value and we get that the length of one side of the square is:

= √15 cm

For the whit area =  x ( √15 -x) + √15 ( √15 - x)  

= (x + √15) (√15 - x)  

=  -x² + 15

Since the two areas are equal, we have;

x²/2  = -x² + 15    

add x² to both sides

3x² / 2   = 15      

multiply both sides by 2/3

x² = 10        

take the positive root of both sides

x = √10cm

Step-by-step explanation:

Answer:

LM ≈ 7.1 in

Step-by-step explanation:

using the Sine rule in Δ LMN

\(\frac{l}{sinL}\) = \(\frac{n}{sinN}\)

where l is the side opposite ∠ L , that is MN

n is the side opposite ∠ N , that is LM

\(\frac{LM}{sin24}\) = \(\frac{MN}{sin67}\) , that is

\(\frac{LM}{sin24}\) = \(\frac{16}{sin67}\) ( cross- multiply )

LM × sin67° = 16 × sin24° ( divide both sides by sin67° )

LM = \(\frac{16sin24}{sin67}\) ≈ 7.1 in ( to the nearest tenth )

The expression E(p) represents the elasticity at point p and by putting the known data we can find the value of elasticity.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a demand function:

q=0. 6(3800-p²)

Differentiate with respect to p:

\(\rm \dfrac{dq}{dp} = -1.2p\)

We know the elasticity:

\(\rm E(p) = \dfrac{dq}{dp}\times\dfrac{p}{q}\)

\(\rm E(p) =-1.2p \times\dfrac{p}{0.6(3800-p^2)}\)

\(\rm E(p) = -\dfrac{2p^2}{(3800-p^2)}\)

Here the data for p and q are not given, but we can find any value using the above expression by putting the known data.

Answer:

Step-by-step explanation:

Answer: a. We can factor the quadratic function f (x) = 8 x^2 - 16 as follows: f (x) = 8 x^2 - 16 = 8 (x^2 - 2) = 8 (x - √2)(x + √2).

b. The x-intercepts of f (x) occur when x = 0, so the x-intercepts are at x = √2 and x = -√2.

c. To find f (-1), we simply plug in -1 for x in the equation f (x) = 8 (x - √2)(x + √2) to get f (-1) = 8 (-1 - √2)(-1 + √2) = 8 (-1 - √2)(-1 - √2) = 8 (-2 - 2√2) = -64 - 64√2.

d. The domain of f (x) is the set of all real numbers, since the quadratic equation f (x) = 8 (x - √2)(x + √2) is defined for all real values of x. The range of f (x) is also the set of all real numbers, since the quadratic equation can produce any real value for f (x) given a real value of x.

e. The inverse of f (x) is denoted as f^(-1)(x), and it is defined as the function that "undoes" the original function. In other words, if we apply the inverse function to the result of the original function, we should get back the original input. For example, if we apply the original function f (x) to some value x, and get the result y, then applying the inverse function to y should give us x back. In this case, the inverse of f (x) is the function f^(-1)(x) = (1/8) x + √2.

f. The domain of the inverse function f^(-1)(x) is the range of the original function f (x), and the range of the inverse function is the domain of the original function. In this case, the domain of f^(-1)(x) is the set of all real numbers (since the range of f (x) is the set of all real numbers), and the range of f^(-1)(x) is also the set of all real numbers (since the domain of f (x) is the set of all real numbers).

g. The relationship between the domain and range of a function and its inverse is that the domain of the inverse is the range of the original function, and the range of the inverse is the domain of the original function.

h. Not all functions and their inverses will have the same relationship between their domains and ranges. For example, a function that is defined only for a certain range of values (such as a square root function, which is only defined for non-negative values of x) will have a restricted domain, and its inverse will have a corresponding restricted range.

The present worth of the tuition cost for a student planning to enroll at the university for 9 years, with the first 4 years costing $7,200 per year and a 5% annual increase for the next 5 years, can be calculated at an interest rate of 8% per year. The present worth is $23,455.297.

To calculate the present worth of the tuition cost, we need to consider the time value of money, which accounts for the fact that money in the future is worth less than money in the present. We can use the concept of present value to determine the worth of future cash flows in today's dollars.

For the first 4 years, the tuition cost is constant at $7,200 per year. To find the present value of these cash flows, we can use the formula for the present value of a fixed cash flow series. Applying this formula, we find that the present value of the first 4 years' tuition cost is

\(7,200 + 7,200/(1+0.08) + 7,200/(1+0.08)^2 + 7,200/(1+0.08)^3.\)

For the next 5 years, the tuition cost increases by 5% per year. We can use the concept of future value to calculate the value of these cash flows in the last year of the 9-year period. Applying the formula for future value, we find that the tuition cost in the last year is \($7,200*(1+0.05)^5.\)

Finally, we can sum up the present value of the first 4 years' tuition cost and the future value of the tuition cost in the last year to obtain the total present worth of the tuition cost for the 9-year period.

The work best fits the art movement of abstract. Abstract art is characterized by the use of shapes, forms, colors, and gestural marks that are not meant to represent specific objects or subjects in a realistic manner.

It emphasizes the visual elements of art, such as line, color, and composition, and often focuses on expressing emotions or conveying abstract concepts. The work in question likely displays non-representational elements, with emphasis on the arrangement of shapes, colors, and forms to create a visual impact that is not tied to recognizable objects or scenes.

In the given work, the absence of identifiable objects or subjects suggests a departure from realistic representation. Instead, the emphasis is placed on the arrangement of abstract elements, such as bold colors, dynamic lines, and geometric shapes. These elements are likely employed to evoke emotions, convey concepts, or explore the purely visual aspects of art. The use of abstraction allows for subjective interpretation and encourages viewers to engage with the work on a more personal and imaginative level. Therefore, the work aligns most closely with the abstract art style or movement.

The statement that a yo-yo has an outer radius of 8cm and an inner radius of 2cm is true.

A yo-yo typically has a circular body with an outer radius and an inner radius where the string attaches. The inner radius is the distance from the center of the yo-yo to where the string is tied, while the outer radius is the distance from the center to the outer edge of the yo-yo. In the case of the yo-yo in question, the inner radius is given as 2cm and the outer radius is given as 8cm.

It is important to note that the difference between the outer and inner radii affects the way the yo-yo behaves during play. The larger the difference between the two radii, the more stable the yo-yo will be during tricks. Additionally, the thickness of the yo-yo body and the weight distribution also play a role in how the yo-yo performs. Overall, the geometry of the yo-yo is an important factor to consider when choosing and using a yo-yo for different types of tricks and styles of play.
