Is an elevation of -10 feet closer or farther from the surface of the ocean than an elevation of -8 feet?

ANSWER

A. (8,9)

EXPLANATION

The point that divides,

[tex]A(x_1,y_1), B(x_2,y_2)[/tex]

in the ratio m:n is given by

[tex]x = \frac{mx_2 + nx_1}{m + n} [/tex]

[tex]y= \frac{my_2 + ny_1}{m + n} [/tex]

The given points are A(0,15) B(20,0)

the ratio is 2:3.

This implies that, m=2,n=3.

[tex]x_1=0,x_2=20,y_1=15,y_2=0[/tex]

We plug in the values to get:

[tex]x = \frac{2 \times 20 + 3 \times 0}{2+ 3} [/tex]

[tex]x = \frac{40}{5} = 8[/tex]

[tex]y= \frac{2 \times 0 + 3 \times 15}{2+ 3} [/tex]

[tex]y= \frac{45}{5} = 9[/tex]

Hence the required point is

(8,9)

  y = -4

Step-by-step explanation:

Once you recognize the line as being horizontal, you know its equation will be ...

  y = (some constant)

The value of the constant will correspond to the y-coordinate of the points the line goes through. It will also be the value of the y-intercept. Here, that value is -4, so the equation is ...

  y = -4

Answer:

y= -4 since it is on the x-axis but does not have any x coordinates

Step-by-step explanation:

Fixed Cost Per Deck = Total Fixed Cost/Estimated Deck Sales

Fixed Cost Per Deck = 85000/13000

Fixed Cost Per Deck  = $7.08

Break Even Point in Units = Fixed Costs/ Sales Price per Unit - Variable Cost

Break Even Point in Units = 85000/11.95 - 3

Break Even Point in Units = 9497

Fixed Cost Per Deck = Total Fixed Cost/Estimated Deck Sales

Fixed Cost Per Deck = 85000/10000

Fixed Cost Per Deck  = $8.50

Break Even Point in Units = Fixed Costs/ Sales Price per Unit - Variable Cost

Break Even Point in Units = 85000/12.95 - 3

Break Even Point in Units = 8543

Break Even Point in Units = Fixed Costs/ Sales Price per Unit - Variable Cost

Break Even Point in Units = 85000/13.45 - 3

Break Even Point in Units = 8134

1.Total Cost = Variable Cost/unit x Units Produced + Fixed cost

Total Cost = (3 x 13000) + 85000

Total Cost = 39000 + 85000

Total Cost = $124000

2.Total Cost = Variable Cost/unit x Units Produced + Fixed cost

Total Cost = (3 x 10000) + 85000

Total Cost = 30000 + 85000

Total Cost = $115000

3. $12.95 and $13.45.

Because the total cost is greater than the revenue.

Let's try at $12.95:

Revenue  = 12.95 x 8000

Revenue = $103600

Total Cost = (3 x 8000) + 85000

Total Cost = 24000 + 85000

Total Cost = $109000

Profit = Revenue - Total Cost

Profit = 103600 - 109000

Profit = $-5400

Now at $13.45:

Revenue = 13.45 x 7000  

Revenue = $94150

Total Cost = (3 x 7000) + 85000

Total Cost = 21000 + 85000

Total Cost = $106000

Profit = Revenue - Total Cost

Profit = 94150 - 106000

Profit = $-11850

4. The fixed costs to produce $13.45 decks is so much greater than the fixed costs to produce 10.95 due to the estimated deck sales.

Answer:

Step-by-step explanation:

(−800)+(−200)+(−50)+(−12.5)+...

This is a Geometric series with common ratio  r =(-200) / ) / (-800)  = 0.25 and first term  a1 = -800.

Sum of n terms = a1 * (1 - r^n) / (1 - r)

Sum of 8 terms = -800 * (1 - 0.25^8) /  (1 - 0.25)

= -800 * 1.333313

= -1066.65.

The sum of the first eight terms of the geometric sequence is given by: −1066.65

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The sum of the first n terms is given by:

[tex]S_n = \frac{a_1(r^n - 1)}{r - 1}[/tex]

In this problem, we have that the first term and the common ratio are, respectively:

[tex]a_1 = -800, q = \frac{-200}{-800} = 0.25[/tex]

Hence, the sum of the first eight terms is given by:

[tex]S_n = \frac{-800(0.25^8 - 1)}{0.25 - 1 } = −1066.65[/tex]

Answer:

30°

Step-by-step explanation:

Call the other end of the chord point B and the center of the circle point O. Then triangle AOB is an equilateral triangle, since OA = OB = AB.

Angle OAB is the internal angle of that triangle, so is 60°. Since OA is perpendicular to the tangent line (makes an angle of 90°), The angle between the tangent line and the chord must be ...

90° - 60° = 30°

___

The other way you know this is that central angle AOB is 60°, and the tangent-to-chord angle is half that, or 30°.

_____

One way to remember the angle relationship between a tangent line and a chord is this:

Consider a point C on long arc AB. The measure of inscribed angle ACB is half the measure of central angle AOB, no matter where C is on the circle. (If C happens to be on the short arc AB, then central angle AOB is a reflex angle, but the relationship still holds.) Consider what happens when C approaches A. The angle at vertex C is still the same: 1/2 the measure of central angle AOB. This remains true even in the limit when points A and C become coincident and line AC is a tangent at point A.

So you know that the carpenter has a board that is 18.5ft long and he wants to cut 1.75ft pieces.

Assume that x is the amount of boards he cuts,

1.75x = 18.5

Isolate x by dividing each side by 1.75.

x = 18.5/1.75 = 10.57 pieces.

Graph both equations and find the X value when the lines cross.

See attached picture of the graph

X = 1

Or you could take logarithms of both sides where log(a^b) = b loga to also find the value of x.

Answer:

x = 1

Step-by-step explanation:

Given in the question,

[tex](16/9)^{-2x+5} = (3/4)^{(x-7)}[/tex]

Take logarithm on both sides

[tex]ln(16/9)^{-2x+5} = ln(3/4)^{(x-7)}[/tex]

Apply power rule of logarithm

(-2x+5)ln(16/9) = (x-7)ln(3/4)

cross multiply

(-2x+5)/(x-7) = [tex]\frac{ln(3/4)}{ln(16/9)}[/tex]

-1/2 = (-2x+5)/(x-7)

-(x-7) = 2(-2x+5)

-x + 7 = -4x + 10

rearrange the terms, x terms to left and constant to right

-x + 4x = 10 - 7

3x = 3

Part 1) The direct proportion is [tex]y=0.8x[/tex]. The graph is located on quadrants I and III

Part 2) The direct proportion is [tex]y=-0.4x[/tex]. The graph is located on quadrants II and IV

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y=kx[/tex]

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Part 1) we have

[tex]y=0.8x-1.6[/tex]

Remember that

If two lines are parallel, then their slopes are the same

In this problem, the slope of the given line is [tex]m=0.8[/tex]

therefore

The direct proportion is [tex]y=0.8x[/tex]

The graph is located on quadrants I and III

Part 2) we have

[tex]y=-0.4+1[/tex]

Remember that

If two lines are parallel, then their slopes are the same

Answer: Option d.

Step-by-step explanation:

To find the domain of the function we should look for the values for which the denominator is equal to zero, because the division by zero is not allowed.

We know by definition that the function [tex]e^x[/tex] is always greater than zero for all x.

We know that the constant c is greater than zero (c>0).

Then, the expression [tex]e^x+c[/tex] is never equal to zero.

Therefore, it does not exist a value for x that makes the denominator 0. Then, the domain of the function is all real numbers.

The answer is the option d.

   Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).

The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.

  The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.

 L = sqrt((2 - -6)^2 + (1 - -1)^2)

 L = sqrt(8^2 + 2^2)

 L = sqrt(64 + 4)

 L = sqrt(68) = 2*sqrt(17)

  W = sqrt((2-3)^2 + (1- -3)^2)

 W = sqrt((-1)^2 + 4^2)

 W = sqrt(1 + 16)

 W = sqrt(17)

  And the area is length * width, so:

 2*sqrt(17)*sqrt(17) = 2 * 17 = 34

  And the total area is the sum of the areas, so

 34 + 6 = 40

  So the area of the figure is 40 square units.

Answer:

Answer:

The correct answer is 6.

Step-by-step explanation:

To find this, first find f(-3)

f(x) = -3x + 9

f(-3) = -3(-3) + 9

f(-3) = 9 + 9

f(-3) = 18

Now we do the same for f(7)

f(x) = -3x + 9

f(7) = -3(7) + 9

f(7) = -21 + 9

f(7) = -12

Now we add them together

18 + -12 = 6

The value of f(?3) + f(7) - f(-3) + f(7) is -24.

To find the Value of f(?3) + f(7) - f(-3) + f(7), we need to substitute the given values into the function f(x) = -3x + 9.

Substituting -3 for x, we get f(?3) = -3(-3) + 9 = 18.
Substituting 7 for x, we get f(7) = -3(7) + 9 = -12.
Substituting -3 for x and adding the results, we get f(-3) = -3(-3) + 9 = 18.
Substituting 7 for x, we get f(7) = -3(7) + 9 = -12.

Now, let's calculate the Value of the expression:
f(?3) + f(7) - f(-3) + f(7) = 18 + (-12) - 18 + (-12) = -24

A kite's symmetrical structure typically forms isosceles triangles due to equal side lengths. Asymmetrical kites generate scalene triangles with varying side lengths, influencing triangle types and angles within based on side intersections.

A kite, with its distinct shape formed by two pairs of adjacent congruent sides, generates triangles within. These triangles can exhibit various properties based on the kite's symmetry. If the kite is symmetrical, the triangles formed tend to be isosceles due to the equal side lengths.

However, asymmetrical kites can yield scalene triangles with sides of varying lengths. The relationship between the kite's structure and the triangle types arises from the lengths and intersections of its sides.

Symmetry tends to create similar or congruent triangles, while asymmetry leads to triangles with differing side lengths. Consequently, the angles within these triangles vary based on the intersection of the kite's sides, resulting in a mix of acute, obtuse, or right angles.

complete the question

What are the possible types of triangles formed within a kite, and how do their properties relate to the structure of the kite? Discuss the potential combinations of isosceles, equilateral, and scalene triangles within a kite, considering the lengths of the sides and the angles formed by the kite's structure."

The domain of Function A, defined as f(x) = -3x + 2, is all real numbers, as it is a linear function with no restrictions on x-values. Function B's domain would depend on its specific definition but is also valid as long as each input maps to a unique output.

The domains of Function A and Function B can be compared based on the definition of a function's domain. The domain is all the input values (x-values) for which a function is defined. Since Function A is defined as f(x) = -3x + 2, it is a linear function without any restrictions on the x values, meaning the domain of Function A is all real numbers.

The description of Function B isn't provided in the question, but from the referenced information, we can understand that Function B is also a function as long as each element of its domain maps to a unique value in its range.

Were we to have the specifics of Function B, we could determine if it also has a domain of all real numbers or whether it has a more restricted domain, such as when a function includes a square root or division by variables which would exclude certain x-values to avoid undefined expressions.

Answer:

[tex]\frac{\pi }{10}[/tex]

Step-by-step explanation:

The area (A) of the sector is calculated using the formula

A  = area of circle × fraction of circle

let x be the measure of the central angle, then

A = πr² × [tex]\frac{x}{2\pi }[/tex] ← substitute values

5π = π × 10² × [tex]\frac{x}{2\pi }[/tex]

5π = 100π × [tex]\frac{x}{2\pi }[/tex] (cancel 50π and 2π )

5π = 50x ( divide both sides by 50 )

x = [tex]\frac{5\pi }{50}[/tex] = [tex]\frac{\pi }{10}[/tex] ← central angle

Final answer:

The measure of the central angle that forms a sector with an area of 5π in a circle of radius 10 is 18 degrees.

Explanation:

To calculate the measure of the central angle that forms the sector of a circle with a radius of 10 units and an area of 5π, we need to use the formula for the area of a sector, which is A = (θ/2) × r², where A is the area of the sector, θ is the central angle in radians, and r is the radius of the circle.

First, let's substitute the given values into the formula:

Now, we can set up the equation:

5π = (θ/2) × 10²

5π = (θ/2) × 100

To find the central angle, we solve for θ:

θ = (2 × 5π) / 100

θ = 0.1π radians

To convert radians to degrees, we use the conversion factor that 180° = π radians:

θ in degrees = 0.1π × (180/π)

θ in degrees = 18°

Therefore, the measure of the central angle that forms the sector is 18 degrees.

1 +csc x  

By csc = [tex]\frac{1}{sinx}[/tex].

Plug the value  csc = [tex]\frac{1}{sinx}[/tex].

1 +  [tex]\frac{1}{sinx}[/tex].
