Northeast Hospital’s Radiology Department is considering replacing an old inefficient X-ray machine with a state-of-the-art digital X-ray machine. The new machine would provide higher quality X-rays in less time and at a lower cost per X-ray. It would also require less power and would use a color laser printer to produce easily readable X-ray images. Instead of investing the funds in the new X-ray machine, the Laboratory Department is lobbying the hospital’s management to buy a new DNA analyzer.

What are differential cost, sunk cost, and opportunity cost?

A differential cost is a cost that arises as the cost difference between two alternatives.

A sunk cost is an irrelevant cost in managerial decisions because it has been incurred already and future decisions cannot overturn it.

An opportunity cost is a benefit that is lost when an alternative is not chosen.

Thus, the above cost classifications depend on the decision to replace the old X-ray machine with a new machine (new X-ray or new DNA analyzer).

opposite side = y

We would find x by applying the Cosine trigonometric ratio which is expressed as

Cos# = adjacent side/hypotenuse

Cos 30 = x/34

Recall,

[tex]\begin{gathered} \cos 30\text{ = }\frac{\sqrt[]{3}}{2} \\ \text{Thus, } \\ \frac{\sqrt[]{3}}{2}\text{ =}\frac{x}{34} \\ 2x=34\sqrt[]{3} \\ x\text{ = }\frac{34\sqrt[]{3}}{2} \\ x\text{ = 17}\sqrt[]{3} \end{gathered}[/tex]

To find y, we would apply the Sine trigonometric ratio. It is expressed as

Sin# = opposite side/hypotenuse

Sin30 y/34

Recall, Sin30 = 0.5. Thus

0.5 = y/34

y = 0.5 * 34

Find the y-intercept of the line represented by the equation: -5x+3y=30

Answers

We need to find the y-intercept of the equation.

For this, we need to use the slope-intercept form:

[tex]y=mx+b[/tex]

Where m represents the slope and b the y-intercept.

Now, to get the form, we need to solve the equation for y:

Then:

[tex]-5x+3y=30[/tex]

Solving for y:

Add both sides 5x:

[tex]-5x+5x+3y=30+5x[/tex][tex]3y=30+5x[/tex]

Divide both sides by 3

[tex]\frac{3y}{3}=\frac{30+5x}{3}[/tex][tex]\frac{3y}{3}=\frac{30}{3}+\frac{5x}{3}[/tex][tex]y=10+\frac{5}{3}x[/tex]

We can rewrite the expression as:

[tex]y=\frac{5}{3}x+10[/tex]

Where 5/3x represents the slope and 10 represents the y-intercept.

The y-intercept represents when the graph of the equations intersects with the y-axis, therefore, it can be written as the ordered pair (0,10).

What is the equation in slope-intercept form of the line that passes through the points (-4,8) and (12,4)?

Answers

ANSWER

y = -0.25 + 7

EXPLANATION

The line passes through the points (-4, 8) and (12, 4).

The slope-intercept form of a linear equation is written as:

y = mx + c

where m = slope

c = y intercept

First, we have to find the slope of the line.

We do that with formula:

[tex]\begin{gathered} m\text{ = }\frac{y_2-y_1}{x_2-x_1} \\ \text{where (x}_1,y_1)\text{ = (-4, 8) } \\ (x_2,y_2)\text{ = (12, 4)} \end{gathered}[/tex]

Therefore, the slope is:

[tex]\begin{gathered} m\text{ = }\frac{4\text{ - 8}}{12\text{ - (-4)}}\text{ = }\frac{-4}{12\text{ + 4}}\text{ = }\frac{-4}{16}\text{ = }\frac{-1}{4} \\ m\text{ = -0.25} \end{gathered}[/tex]

Now, we use the point-slope method to find the equation:

[tex]\begin{gathered} y-y_{1\text{ }}=m(x-x_1) \\ \Rightarrow\text{ y - 8 = -0.25(x - (-4))} \\ y\text{ - 8 = -0.25(x + 4)} \\ y\text{ - 8 = -0.25x - 1} \\ y\text{ = -0.25x - 1 + 8} \\ y\text{ = -0.25x + 7} \end{gathered}[/tex]

That is the equation of the line. It is not among the options.

the population of a town grows at a rate proportional to the population present at time t. the initial population of 500 increases by 15% in 10 years. what will be the pop ulation in 30 years? how fast is the population growing at t 30?

Answers

Using the differential equation, the population after 30 years is 760.44.

What is meant by differential equation?In mathematics, a differential equation is a relationship between the derivatives of one or more unknown functions. Applications frequently involve a function that represents a physical quantity, derivatives that show the rates at a differential equation that forms a relationship between the three, and a function that represents how those values change.A differential equation is one that has one or more functions and their derivatives. The derivatives of a function define how quickly it changes at a given location. It is frequently used in disciplines including physics, engineering, biology, and others.

The population P after t years obeys the differential equation:

dP / dt = kP

Where P(0) = 500 is the initial condition and k is a positive constant.

∫ 1/P dP = ∫ kdtln |P| = kt + C|P| = e^ce^kt

Using P(0) = 500 gives 500 = Ae⁰.

A = 500.Thus, P = 500e^kt

Furthermore,

P(10) = 500 × 115% = 575sO575 = 500e^10ke^10k = 1.1510 k = ln (1.15)k = In(1.15)/10 ≈ 0.0140Therefore, P = 500e^0.014t.

The population after 30 years is:

P = 500e^0.014(30) = 760.44

Therefore, using the differential equation, the population after 30 years is 760.44.

The given situation can be written in an algebraic way.

If pathos age is a, and Yamir age is b. You have:

Yamir is twice as old as pato:

b = 2a

in three years, the sum of their ages will be 30:

(b + 3) + (a + 3) = 30

replace the b = 2a into the last equation, and solve for a, just as follow:

2a + 3 + a + 3 = 30 simplify like terms left side

3a + 6 = 30 subtract 6 both sides

3a = 30 - 6

3a = 24 divide by 3 both sides

a = 24/3

If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

△HUG and △LAB each have one angle measuring exactly 63°. Corresponding sides g and b are congruent. Sides h and l are congruent.

A side, an included angle, and a side on △HUG and on △LAB are congruent. So, by SAS, the two triangles are congruent.

Angle Side Angle Postulate

If two angles and the included side of a triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

We have △MAC and △CHZ, with side m congruent to side c. ∠A is congruent to ∠H, while ∠C is congruent to ∠Z. By the ASA Postulate these two triangles are congruent.

Angle Angle Side Theorem

We are given two angles and the non-included side, the side opposite one of the angles. The Angle Angle Side Theorem says,

If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.

Here are congruent △POT and △LID, with two measured angles of 56° and 52°, and a non-included side of 13 centimeters:

By the AAS Theorem, these two triangles are congruent.

HL Postulate

Exclusively for right triangles, the HL Postulate tells us,

Two right triangles that have a congruent hypotenuse and a corresponding congruent leg are congruent.

The hypotenuse of a right triangle is the longest side. The other two sides are legs. Either leg can be congruent between the two triangles.

Here are right triangles △COW and △PIG, with hypotenuses of sides w and i congruent. Legs o and g are also congruent:

To determine which ordered pair is a solution to the equation we shall substitute the values of x and y in the ordered pair.

Taking the first ordered pair;

[tex]\begin{gathered} \text{For;} \\ 3x-5y=-13 \\ \text{Where;} \\ (x,y)\Rightarrow(9,8) \\ 3(9)-5(8)=-13 \\ 27-40=-13 \\ -13=-13 \end{gathered}[/tex]

This means the ordered pair (9, 8) is a solution.

We can also solve this graphically a follows;

Observe from the graph attached that the solution to the equation shown above is indicated at the point where x = 9 and y = 8.

The other ordered pairs in the answer options cannot be found on the line which simply mean they are not solutions to the equation given.

ANSWER:

The ordered pair (9, 8) is a solution to the equation 3x - 5y = -13

Solve the equation for w.

4w + 2 + 0.6w = −3.4w − 6

No solution

w = 0

w = 1

w = −1

Answers

Answer:

w = -1

Step-by-step explanation:

Given equation:

[tex]4w + 2 + 0.6w=-3.4w-6[/tex]

Add 3.4w to both sides:

[tex]\implies 4w + 2 + 0.6w+3.4w=-3.4w-6+3.4w[/tex]

[tex]\implies 4w + 2 + 0.6w+3.4w=-6[/tex]

Subtract 2 from both sides:

[tex]\implies 4w + 2 + 0.6w+3.4w-2=-6-2[/tex]

[tex]\implies 4w +0.6w+3.4w=-6-2[/tex]

Combine the terms in w on the left side of the equation and subtract the numbers on the right side of the equation:

[tex]\implies 8w=-8[/tex]

Divide both sides by 8:

[tex]\implies \dfrac{8w}{8}=\dfrac{-8}{8}[/tex]

[tex]\implies w=-1[/tex]

Therefore, the solution to the given equation is:

[tex]\boxed{w=-1}[/tex]

Given that,

→ 4w + 2 + 0.6w = -3.4w - 6

Now the value of w will be,

→ 4w + 2 + 0.6w = -3.4w - 6

→ 4.6w + 2 = -3.4w - 6

→ 4.6w + 3.4w = -6 - 2

→ 8w = -8

→ w = -8/8

→ [ w = -1 ]

Hence, the value of w is -1.
