1. Joe has a chocolate box whose shape resembles a rectangular prism. Its length is 6 in, height is 2 in and width is 4 in. Find the volume of the box.

length= 5 in , width= 4 in, height= 3 in

The segment lengths on the right triangle are given as follows:

The three trigonometric ratios are the sine, the cosine and the tangent, and they are defined as follows:

The sum of the internal angle measures of a triangle is of 180º, hence the missing angle is given as follows:

m < L = 180 - (30 + 60)

m < L = 90º.

Hence the segment JL represents the hypotenuse of the figure.

JL is opposite to the angle K, hence it's length is obtained as follows:

sin(30º) = JL/26

1/2 = JL/26

2JL = 26

JL = 13.

Segment KL is adjacent to the angle of 30º, hence it's length is obtained as follows:

cos(30º) = KL/26

[tex]\frac{\sqrt{3}}{2} = \frac{KL}{26}[/tex]

[tex]2KL = 26\sqrt{3}[/tex]

[tex]KL = 13\sqrt{3}[/tex]

The perimeter of the rectangle is P = 18 units

Given data ,

Let the rectangle be represented as ΔWXYZ

Now , the coordinates of the triangle are

W ( 3 , 3 ) , X ( 8 , 3 ) , Y ( 8 , 7 ) and Z ( 3 , 7 )

The perimeter of the rectangle = 2 ( length + width )

The width of the rectangle W = ( 7 - 3 ) = 4 units

The length of the rectangle L = ( ( 8 - 3 ) = 5 units

So , P = 2 ( 4 + 5 )

P = 2 x 9

P = 18 units

The correct answer is option B:

⇒ Y decreases and X increases.

Given that;

the y value starts to decrease and the x value remains the same over time.

Now, We know that;

the slope remains constant, but the y value decreases as you move along the slope in the negative y direction, while the x value increases.

Hence,

If the y value starts to decrease while the x value remains the same over time on a consistent slope,

Thus, The correct answer is option B:

The return on equity (ROE) for a project financed with 100% equity or 50% equity and 50% debt, given different levels of earnings before interest and taxes (EBIT) are 20.3%, -5.4%, 36.2% and  -20.3% respectively. So, the correct answers are A), B), A) and A). if Galaxy Corp. proceeds with a recapitalization then  Basic earning power (BEP), Return on assets (ROA), Net income are likely to increase. The correct option is A), B) and E).

ROE = EBIT*(1 - T)/Total Equity

Where T is the tax rate and Total Equity is the amount of equity used to finance the project.

If the EBIT is $145,000, then

ROE = $145,000*(1 - 0.30)/$500,000 = 20.3%

Therefore, the answer is 20.3%. So, the correct answer is A).

If the EBIT is -$45,000, then

ROE = -$45,000*(1 - 0.30)/$500,000 = -5.4%

Therefore, the answer is -5.4%. So, the correct answer is B).

If the project is financed with 50% equity and 50% debt at an interest rate of 11%, then the cost of equity can be calculated as follows

Cost of Equity = EBIT*(1 - T)/Total Equity

Cost of Debt = Interest Rate*(1 - T)

Weighted Average Cost of Capital (WACC) = Cost of Equity*(Equity/Total Capital) + Cost of Debt*(Debt/Total Capital)

ROE = EBIT*(1 - T)/Total Equity

ROE = [$145,000*(1 - 0.30)/($500,0000.50)] + [$145,000(1 - 0.30)0.50/($500,0000.50)*(1 - 0.11)]

ROE = 36.2%

Therefore, the answer is 36.2%. So, the correct answer is A).

If the project is financed with 50% equity and 50% debt at an interest rate of 11%, and the EBIT is -$45,000, then

ROE = -$45,000*(1 - 0.30)/($500,0000.50) + [-$45,000(1 - 0.30)0.50/($500,0000.50)*(1 - 0.11)]

ROE = -20.3%

Therefore, the answer is -20.3%. So, the correct answer is A).

If Galaxy Corp. proceeds with the recapitalization, the cost of debt is likely to increase since the firm is issuing new long-term debt. Therefore, the cost of debt (rdrd) will increase.

However, the basic earning power (BEP) and return on assets (ROA) are likely to increase since the firm will have a higher proportion of debt in its capital structure, which will increase the financial leverage of the firm.

As a result, the net income of the firm may also increase. The cost of equity (rsrs) may or may not change depending on how the market perceives the increased financial risk associated with the higher debt level.

Therefore, the items that are likely to increase are Basic earning power (BEP), Return on assets (ROA), Net income. The correct answer is A), B) and E).

The boat is moving at 48 mph while the current is moving at 9 mph in still water.

Let's use the letters "B" for the boat's speed in still water and "C" for the current's speed.

The boat's effective speed upstream is B - C because it is moving against the current.

Since the boat is moving downstream against the tide, its effective speed is equal to B plus C.

Based on the supplied data, we can construct the following two equations:

234 = 6(B - C)

342 = 6(B + C)

Making these equations simpler:

39 = B - C

57 = B + C

Now that we have added the two equations, we may solve for B and C:

39 + 57 = 2B

96 = 2B

B = 48

Therefore, the boat's speed in calm water is 48 mph.

To find C, we can rewrite one of the initial equations with this value as a substitute:

39 = 48 - C C = 9

Thus, the current is moving at a 9 mph velocity.

Therefore, the boat is moving at 48 mph while the current is moving at 9 mph in still water.

Answer:

The last option

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

Step-by-step explanation:

Given equation is 6x - y = 14

To convert an equation in rectangular(cartesian) form, f(x, y) to polar f(r, θ) we use the following information

x = rcosθ

y = rsinθ

Substituting for x and y in the original rectangular equation 6x - y = 14,

6(rcosθ) - rsinθ = 14

Factoring out r on the left side,
r(6cosθ - sinθ) = 14

The direction angle of the vector with initial point (1, -1) and terminal point (7, 2) is approximately 26.57 degrees, found by calculating the arctangent of the ratio of the y and x components of the vector.

The direction angle of the vector v is the angle it makes with the positive x-axis, measured counterclockwise.

To find this angle, we need to calculate the difference between the y-coordinates and x-coordinates of the terminal and initial points of the vector, respectively. Then, we can use the arctangent function to find the angle.

Let's first find the components of the vector v

v = <7 - 1, 2 - (-1)> = <6, 3>

Now, we can find the direction angle as follows

θ = arctan(3/6)

θ = 0.4636 radians (in decimal form)

To convert this to degrees, we can multiply by 180/π

θ ≈ 26.57°
