Answer:

y = 3x

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{3}[/tex] x + 4 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then

y = 3x + c ← is the partial equation

to find c substitute (- 1, - 3 ) into the partial equation

- 3 = 3(- 1) + c = - 3 + c ( add 3 to both sides )

y = 3x + 0 , that is

y = 3x

Based upon this information, (2) I and III only statements can be proven.

From the given information, we can prove that statement II is true, i.e., BD bisects ABC.

Proof:

Since BD is the perpendicular bisector of ADC, we have AD = CD and ∠ADB = ∠CDB = 90°. Thus, triangles ABD and CBD are congruent (by the hypotenuse-leg congruence criterion), which implies AB = BC and ∠ABD = ∠CBD. Therefore, BD bisects ∠ABC.

However, we cannot prove that statements I or III are true based solely on the given information.

Statement I (BD is a median) would be true if we had additional information that AD = DB = DC, but this is not necessarily true based on the given information.

Statement III (△ABC is isosceles) would be true if we had additional information that AB = BC, but this is not necessarily true based on the given information. In fact, it is only guaranteed that AB = BC if AD = BD = DC, which is not necessarily the case.

Therefore, the correct answer is (2) I and III, only.

The height of the tree to the nearest hundredth of a meter is 10.77m.

Detailed explanation:

An illustration of identical triangles is shown in the diagram. View the illustration I included with my response to see how triangles can be used to solve this issue.

Because they both share an internal angle, the triangles made by Alyssa and her shadow and the triangle created by the tree and its shadow are examples of comparable triangles.

The ratios of the comparable sides on both sides are proportionate according to the similar triangles theorem.

Therefore, in order to determine the height of the tree, we must make a percentage of the corresponding sides of both triangles. Let x equal the tree's height.

[tex]\frac{BE}{BC} =\frac{DE}{AC}[/tex]

BE = 4.25 meters

DE = 1.65 meters

BC = 27.75 meters

AC = x meters

[tex]\frac{4.25}{27.75} =\frac{1.65}{x}[/tex]

Cross multiply is now used to find x.

Answer:

270 square units

Step-by-step explanation:

The area of a regular hexagon is given by the equation:

A = (1/2)(a · P)

where a is the hexagon's apothem and P is its perimeter.

1. We can first solve for the hexagon's perimeter by multiplying its side length (given as 15) by 6, since there are 6 sides.

P = 15 · 6 = 90

2. Now, we can plug that perimeter value into the formula for the area of a regular hexagon (above).

A = (1/2)(90 · 6)

A = (1/2)(540)

A = 270 square units

Answer:

Second Option  :  21

Step-by-step explanation:

At 1080 ml per day for 7 days, the patient would have to ingest 1080 x 7 = 7,560 ml

Since the can capacity is given in oz we have to convert both values to the same units

1 ml = 0.033814 fl oz

Therefore 7,560 ml ≡ 7,560 ml x 0.033814 fl oz

= 255.634 oz

Since each can holds 12 oz, the number of cans = 255.634/12

From the answer choices, the closest to this value is Second  Option : 21 cans

The two provided payments of $17,000 and $3,300 due in 1 year and 2 years, respectively, would be replaced by two equal payments of $2,287.87 made in 6 months and 5 years.

To solve this problem, we need to find two equal payments that would replace the two given payments, given the time and interest rate. We can use the present value formula to calculate these payments:

PV = C / (1 + r)^n

Where

PV is the present value,  

C is the future value of the payment,

r is the interest rate per compounding period, and

n is the number of compounding periods.

For the first payment of $17,000 due in 1 year, its present value in 6 months can be calculated as:

PV1 = 17,000 / (1 + 0.08/4)^(2*2) = $14,785.28

For the second payment of $3,300 due in 2 years, its present value in 5 years can be calculated as:

PV2 = 3,300 / (1 + 0.08/4)^(4*2) = $2,424.67

To find the equal payments that would replace these two payments, we can use the annuity formula:

PMT = PV / [(1 - (1 + r)^(-n)) / r]

Where

PMT is the equal payment,

PV is the present value,

r is the interest rate per compounding period, and

n is the number of compounding periods.

For the two payments to be made in 6 months and 5 years, respectively, the total number of compounding periods is

4*2.5 = 10.

The equal payment can be calculated as follows:

PMT = (PV1 + PV2) / [(1 - (1 + 0.08/4)^(-10)) / (0.08/4)] = $2,287.87

Therefore, two equal payments of $2,287.87 made in 6 months and 5 years would replace the two given payments of $17,000 and $3,300 due in 1 year and 2 years, respectively.

The value of x from the given triangle is approximately 19.10.

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

We can use the Pythagorean theorem to find the value of x. The theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, it can be represented as follows:

c² = a²+ b²

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

In this problem, c = 25, and we need to find the value of x which is the length of one of the other two sides. Let's call the other side y. Then, we can write the equation as follows:

25² = x² + y²

We are also given that the angle between x and y is 41 degrees. We can use trigonometry to find the value of y. The sine function gives us the ratio of the opposite side to the hypotenuse, so we can write:

sin(41) = y/25

Therefore, y = 25 * sin(41). Now that we have the values of x and y, we can substitute them in the equation derived from the Pythagorean theorem:

25² = x² + (25 * sin(41))²

Solving for x, we get:

x = √(25²- (25 * sin(41))²)

Using a calculator, we get that sin(41) = 0.661437827766148.

Now, we can substitute this value in the equation:

x = √(25² - (25 * sin(41))²)

x = √(25² - (25 * 0.661437827766148)²)

x = √(25² - (16.0359050108801)²)

x = √(625 - 256.132749101278)

x = √(368.867250898722)

x = 19.10

Hence, The value of x is approximately 19.10

A maximum profit of $840 can be earned by investing;

$3,000 in stock A

$6,000 in stock B

$7,000 in stock C

Linear programming is a optimization technique that helps in determining the maximizing or minimizing parameters of linear functions.

The parameters in the question, obtained from a similar question obtained online includes;

The amount available to be invested = $16,000

The expected returns for stock A = 4%

The expected return for stock B = 5%

Expected returns for stock C = 6%

Amount to be invested in each stock ≥ $1,000

Amount to be invested in stock C ≤ $7,000

Amount invested in C ≤ 4 × Amount invested in stock A

Amount invested in stock B ≤ 2 × Amount invested in stock A

Let x represent the amount invested in stock A, let y represent the amount invested in stock B therefore;

The amount invested in stock C = 16,000 - x - y

16,000 - x - y ≥ 1000...(1)

16,000 - x - y ≤ 7000...(2)

16,000 - x - y ≤ 4·x...(3)

Therefore, we get;

- y ≥ 1000 - 16,000 = -15000 + x

-y ≥ -15000 + x

16,000 - x - y ≤ 7000

16,000 - x - y ≤ 4·x

-y ≤ 4·x + x = 5·x - 16,000

-y ≤ 5·x - 16,000  

The vertices of the feasible regions on the graph of the inequalities are;

(5,000, 10,000), (3,000, 6,000), (8,000, 1,000), and (14,000, 1,000)

The profit function is;

Profit = 0.04·x + 0.05·y + 0.06·(16000 - x - y)

Plugging in the value of the vertices of the feasible region in the profit function, we get;

Point (5,000, 10,000)

Profit = 0.04 × 5000 + 0.05 × 10000 + 0.06 × (16000 - 5000 - 10000) = 760

Point (3,000, 6,000)

Profit = 0.04 × 3000 + 0.05 × 6000 + 0.06 × (16000 - 3000 - 6000) = 840

Point (8,000, 1,000)

Profit = 0.04 × 8000 + 0.05 × 1000 + 0.06 × (16000 - 8000 - 1000) = 790

(14,000, 1,000)

Profit = 0.04 × 14000 + 0.05 × 1000 + 0.06 × (16000 - 14000 - 1000) = 670

Therefore, the maximum profit of $840 is earned by investing $3,000 in stock A and $6,000 in stock B which indicates that the investment in stock C is $16,000 - $3,000 - $6,000 = $7,000

Answer:

each parking ticket costs $100 and each traffic violation costs $124.28.

Step-by-step explanation:

To find out the cost of each parking ticket and each traffic violation, we can set up two equations using the information given:

Let x be the cost of each parking ticket.

In the first month, 3 parking tickets cost 3x, and 14 traffic violations cost 14y.

The total cost for the first month is 2030, so we have:

3x + 14y = 2030

In the second month, 11 parking tickets cost 11x, and 11 traffic violations cost 11y.

The total cost for the second month is 2200, so we have:

11x + 11y = 2200

Now that we have two equations, we can use substitution to find the value of x and y.

From the first equation, we can solve for y:

y = (2030 - 3x) / 14

Substituting this expression for y into the second equation:

11x + 11((2030 - 3x) / 14) = 2200

Expanding the expression for y and simplifying the equation:

11x + 2030 - 33x / 14 = 2200

Multiplying both sides by 14:

154x + 28420 = 30800

Solving for x:

x = $100

So each parking ticket costs $100, and each traffic violation costs:

y = (2030 - 3x) / 14 = (2030 - 3 * 100) / 14 = (2030 - 300) / 14 = 1730 / 14 = $124.28

Therefore, each parking ticket costs $100 and each traffic violation costs $124.28.

Answer:

-727.41 dollars

Step-by-step explanation:

To find the cost of each parking ticket and each traffic violation, we can set up a system of two equations. Let's call the cost of a parking ticket "x" and the cost of a traffic violation "y".

For the first month:

3x + 14y = 2030

For the second month:

11x + 11y = 2200

We can solve for x and y using any method, such as substitution or elimination. For this problem, let's use substitution.

First, we'll solve for x in the first equation:

3x + 14y = 2030

3x = 2030 - 14y

x = (2030 - 14y) / 3

Next, we'll substitute this expression for x into the second equation:

11x + 11y = 2200

11((2030 - 14y) / 3) + 11y = 2200

2030 - 14y + 11y = 2200 * 3 / 11

2030 - 3y = 636

-3y = -1394

y = 464.67

Finally, we'll substitute this value of y back into the first equation to find x:

3x + 14y = 2030

3x + 14(464.67) = 2030

3x = 2030 - 6544.68

x = (2030 - 6544.68) / 3

x = -2180.23 / 3

x = -727.41

So each parking ticket costs approximately -727.41 dollars, and each traffic violation costs approximately 464.67 dollars. However, since these values are negative, it means the suspect has received a credit rather than being charged for these fees.
