The given statement is false: vertical angle do not depend on the line being parallel. A pair of vertical angles are always congruent.

Vertical angle:

Vertical angle means that the angles opposite each other when two lines cross.

Given,

Here we have the diagram and we also know that angle 7 is congruent to angle 5.

Now we need to find the given statement is true or not.

Through the given diagram, we have identified that, the eight angles will together form four pairs of corresponding angles.

Angles 1 and 5 constitutes one of the pairs.

We know that all the corresponding angles are congruent.

All angles that have the same position with regards to the parallel lines and the transversal are corresponding pairs e.g. 3 + 7, 4 + 8 and 2 + 6.

Through that we know that basically, the vertical angles are always congruent, which means that they are equal. So, it is not necessary for them to be parallel.

much HST did Colin pay on his trip? Answer should be rounded off to whole number.

Answers

The Harmonized Sales Tax paid by Colin is $152.

What is Harmonized Sales Tax?Almost all buyers of taxable supplies of goods and services must pay the GST/HST (other than zero-rated supplies). Indians, Indian bands, and entities with band authority, however, are occasionally exempt from having to pay the GST/HST on taxable supplies. In Ontario, the HST (Harmonized Sales Tax) is 13%. Ontario offers a point-of-sale rebate for the 8% provincial HST exemption on a selection of goods.

So, the amount of HST Colin pays:

The total amount of items brought:

Skis: $879.95Boom box: $145.58Souvenir: $99.97Maple syrup: $45.14

Total amount: $1,170.64

We know that HST is 13% of the amount, then:

$1,170.64/100 × 13 = 152.1832Rounding off: $152

Therefore, the Harmonized Sales Tax paid by Colin is $152.

Which set of sides would make a right triangle? 5,10,12 8,10,12 5,12,13 4,5,6

Answers

Our answer are the sides 5,12 and 13 which represent a Pythagoraen triple

The sides of a triangle that would make a right-triangle are collectively called a Pythagorean triple

These measures stem from the Pythagoras theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides

How to evaluate operations of functions

In this problem we four cases of operations between two functions, a quadratic equation f(x) and a linear equation g(x). There are four operations:

Addition - f (x) + g (x) = (f + g) (x)

Subtraction - f (x) - g(x) = (f - g) (x)

Multiplication - f (x) · g (x) = f · g (x)

Division - f (x) / g (x) = (f / g) (x)

If we know that f(x) = x² - x and g(x) = 3 · x + 9, then the compositions of functions evaluated at x = - 2 are, respectively:

(f + g) (- 2) = (- 2)² - (- 2) + 3 · (- 2) + 9

(f + g) (- 2) = 4 + 2 - 6 + 9

(f + g) (- 2) = 9

(f - g) (- 2) = (- 2)² - (- 2) - 3 · (- 2) - 9

(f - g) (- 2) = 4 + 2 + 6 - 9

(f - g) (- 2) = 3

(f · g) (- 2) = [(- 2)² - (- 2)] · [3 · (- 2) + 9]

(f · g) (- 2) = 6 · 3

F)

[tex]\begin{equation*} P^{\prime}(1100)=26 \end{equation*}[/tex]

Explanation:

Given:

[tex]\begin{gathered} p=180-\frac{q}{50} \\ C(q)=72000+110q \end{gathered}[/tex]

where q = the number of microwaves that can be sold at a price of p dollars per unit

C(q) = the total cost (in dollars) of producing q units.

A) To find the marginal cost, C'(q), we'll go ahead and take the derivative of the total cost as seen below;

[tex]\begin{gathered} C(q)=72000+110q \\ C^{\prime}(q)=0+110 \\ \therefore C^{\prime}(q)=110 \end{gathered}[/tex]

So the marginal cost, C'(q) = 110

B) We'll go ahead and determine the revenue function, R(q), by multiplying the price, p, by the quantity, q, as seen below;

[tex]\begin{gathered} R(q)=p*q=(180-\frac{q}{50})q=180q-\frac{q^2}{50} \\ \therefore R(q)=180q-\frac{q^2}{50} \end{gathered}[/tex]

C) We'll go ahead and determine the marginal revenue function, R'(q), by taking the derivative of the revenue function, R(q);

[tex]\begin{gathered} \begin{equation*} R(q)=180q-\frac{q^2}{50} \end{equation*} \\ R^{\prime}(q)=180-\frac{2q^{2-1}}{50}=180-\frac{q}{25} \\ \therefore R^{\prime}(q)=180-\frac{q}{25} \end{gathered}[/tex]

D) To evaluate the marginal revenue function at q = 1100, all we need to do is substitute the q with 1100 in R'(q) and simplify;

[tex]\begin{gathered} \begin{equation*} R^{\prime}(q)=180-\frac{q}{25} \end{equation*} \\ R^{\prime}(1100)=180-\frac{1100}{25}=180-44=136 \\ \therefore R^{\prime}(1100)=136 \end{gathered}[/tex]

Therefore, R'(1100) is 136

E) To find the profit function, P(q), we have to subtract the total cost, C(q), from the revenue cost, R(q);

[tex]\begin{gathered} P(q)=R(q)-C(q) \\ =(180q-\frac{q^2}{50})-(72,000+110q) \\ =180q-\frac{q^2}{50}-72000-110q \\ =-\frac{q^2}{50}+180q-110q-72000 \\ =-\frac{q^2}{50}+70q-72000 \\ \therefore P(q)=-\frac{q^2}{50}+70q-72000 \end{gathered}[/tex]

F) To Evaluate the marginal profit function at q = 1100, we have to first determine the marginal profit, P'(q), by taking the derivative of the profit function, P(x);

[tex]\begin{gathered} \begin{equation*} P(q)=-\frac{q^2}{50}+70q-72000 \end{equation*} \\ P^{\prime}(q)=-\frac{2q^{2-1}}{50}+70(1*q^{1-1})-0=-2q^{50}+70q^0=-\frac{q}{25}+70 \\ \therefore P^{\prime}(q)=-\frac{q}{25}+70 \end{gathered}[/tex]

We can now go ahead and find P'(1100) as seen below;

[tex]\begin{gathered} P^{\prime}(1100)=-\frac{1100}{25}+70=-44+70=26 \\ \therefore P^{\prime}(1100)=26 \end{gathered}[/tex]

So P'(1100) = 26

Joe drinks 0.55 L of milk every day. How much milk does he drink in 5 days? Write your answer in milliliters.

Answers

Given that

Joe drinks 0.55 l of milk every day and we have to find the milk he can drink in 5 days.

Explanation -

Let the given condition be represented as

1 day = 0.55 L milk

So multiplying by 5 on both sides we have

1 x 5 days = 0.55 x 5 L milk

5 days = 2.75 L milk

And conversion is

1L = 1000 ml

So multiplying by 2.75 in the above equation we have

2.75L = 2.75 x 1000 ml = 2750 ml

So Joe will drink 2750 ml of milk in 5 days.

Hence the final answer is 2750 ml.

Answers

The maximum value increase along with the down payment is $1200.

What is Down Payment?

A down payment, sometimes known as a deposit in British English, is an upfront partial payment made when purchasing expensive goods or services like a home or car. At the moment the transaction is completed, it is often paid in cash or an equivalent. The remainder of the payment must then be financed using some kind of loan.

We need to calculate the value by which the price increases if she does raise the payment by $30

So, the total payment made by her = $140 +$30 = $170

This payment is made for 48 months at 5% simple interest

Total payments made= $170 × 48 = $8160

Let P be the total car value

P + SI = 8160

P + PTR = 8160

P(1+TR) = 8160

P = 8160/ (1+0.05 × 48 /12)

P= $6800

The maximum price that can be done is $6800 + down payment

hence the maximum price is $7800

Hence, the maximum value increase =$7800 - $6600= $1200

On a flight from Chicago, Illinois, to Denver, Colorado,
the typical cruising altitude of a passenger jet is approximately
38,000 feet. As the flight departs from O'Hare International Airport,
the jet begins to ascend. At 4.3 miles away from the airport, the jet
is at an altitude of 4200 feet. The jet reaches an altitude of 36,700
feet at 167.5 miles away from the airport.
Determine the slope of ascent of the flight given that 5280 feet = 1 mile.
Round your answer to the nearest thousandth.

Answers

The slope of ascent of the flight is 0.04

How to calculate the slope of ascent?

From the question, we have the following parameters that can be used in our computation:

Typical cruising altitude = 38,000 feetInitial point of ascend = 4.3 miles at 4,200 feetAnother point of ascend = 167.5 miles at 36,700 feet

The above parameters can be represented as

(x, y) = (4.3, 4200) and (167.5, 36,700)

The slope is then calculated as

Slope = (y₂ - y₁)/(x₂ - x₁)

Where x and y are defined above

So, we have

Slope = (36700 - 4200)/(167.5 - 4.3)

Evaluate

Slope = 199.14 feet per mile

Recall that 5280 feet = 1 mile.

So, we have

Slope = 199.14 feet/5280 feet

Evaluate

Slope = 0.04

The next step is to re-arrange the above equation in the slope-intercept format

[tex]\begin{gathered} \text{Given the equation of a straight line as} \\ x\text{ + 3y = -15} \\ \text{Isolate 3y by substracting x from both sides} \\ x\text{ - x + 3y = -15 - x} \\ 3y\text{ = -x - 15} \\ \text{Divide through by 3} \\ \frac{3y}{3}\text{ = }\frac{-1}{3}x\text{ -}\frac{15}{3} \\ y\text{ = }\frac{-1}{3}x\text{ - 5} \\ \text{Hence, the slope}-\text{intercept form of the above equation is given as} \\ y\text{ = }\frac{-1}{3}x\text{ - 5} \end{gathered}[/tex]

NB: That the two lines are perpendicular to each other

From y = mx + b

m = -1/3

The slope of the equation

[tex]\begin{gathered} \text{ For two perpendicular lines, we can calculate the slope as follows} \\ m_1\cdot m_2\text{ =- 1} \\ \text{where m}_1\text{ = }\frac{-1}{3} \\ \frac{-1}{3}\cdot m_2\text{ = -1} \\ \frac{-1\cdot m_2}{3}=\text{ -1} \\ \text{Cross multiply} \\ -m_2\text{ = -1 }\cdot\text{ 3} \\ -m_2\text{ = -3} \\ \text{Divide through by -1} \\ \frac{-m_2}{-1}\text{ = }\frac{-3}{-1} \\ m_2\text{ = }3 \\ \text{Hence, the slope of the perpendicular line to the equation is 3} \end{gathered}[/tex]

Maya is playing golf. On her first two holes she scored one under par then six over par. Find her score after the first two holes.

Answers

The constant of proportionality for the given set is 3.

Given,

The set;

x        y

12     36

18     54

25    75

We have to find the constant of proportionality;

Here,

y = x × r

Where r is the constant of proportionality.

Lets see;

Case 1; 12 and 36

36 = 12 × r

r = 36/12

r = 3

Case 2; 18 and 54

54 = 18 × r

r = 54/18

r = 3

Case 3; 25 and 75

75 = 25 × r

r = 75/25

r = 3

Therefore,

The constant of proportionality for the given set is 3.
