Micheal wants to buy an efficient smart car that according to the latest EPA standards gets 33 mpg in the city and 40 mpg on the highway. The car that Micheal picked out costs $16,100. His dad agreed to purchase the car if Michael would pay it off in equal monthly payments for the next 70 months. The equation y= -230x+16,100 represents the amount, Y (in dollars), that Michael owes his father after X months.


A) How much does Michael owe his dad after six months?

B) determine the slope of the line and interpret its meaning in the context of this problem.


1) Micheal owes his father $[ ] after 6 months.


2) The slope is [ ]


3) The amount Michael owes his father [choose one] by $[ ] per month.

The trigonometric identity presented in this problem is proved trough the answer, reaching an answer 1 = 1.

The identity is presented as follows:

[tex]\csc{\beta} + 1 = \frac{\cot{\beta}}{\sec{\beta} - \tan{\beta}}[/tex]

Then we take the right side of the denominator, and apply the subtraction of perfect squares to the denominator, as follows:

[tex]\frac{\cot{\beta}}{\sec{\beta} - \tan{\beta}} \times \frac{\sec{\beta} + \tan{\beta}}{\sec{\beta} + \tan{\beta}} = \frac{\cot{\beta}(\sec{\beta} + \tan{\beta})}{\sec^{2}{\beta} - \tan^2{\beta}}[/tex]

The following identity relates the square of the secant and of the tangent:

[tex]\tan^2{\beta} + 1 = \sec^2{\beta}[/tex]

Hence:

[tex]\sec^2{\beta} - \tan^2{\beta} = 1[/tex]

Thus the remaining expression is:

[tex]\frac{\cot{\beta}(\sec{\beta} + \tan{\beta})}{\sec^{2}{\beta} - \tan^2{\beta}} = \cot{\beta}(\sec{\beta} + \tan{\beta})[/tex]

The equations of the cotangent, secant and tangent are given as follows:

Hence:

[tex]\cot{\beta}(\sec{\beta} + \tan{\beta}) = \frac{\cos{\beta}}{\sin{\beta}}\left(\frac{1}{\cos{\beta}} + \frac{\sin{\beta}}{\cos{\beta}}\right) = \frac{1}{\sin{\beta}} + 1[/tex]

One divided by the sine is the cosecant, as follows:

[tex]\frac{1}{\sin{\beta}} = \csc{\beta}[/tex]

Hence the simplified expression is:

[tex]\csc{\beta} + 1[/tex]

Which is equivalent to the right side of the expression, hence an identity of the format 1 = 1 is reached and the identity is proven.

v=780

Answer:

v = 12

The slope is 5 and the y-intercept is -2000.

(b) The slope tells us about the rate of change in weekly profit and the y-intercept tells us about the minimum profit.

(c) The situation can be modeled as y = 5x -200. Here, y= profit per week and x= number of customers per week.

(d) If the state world roller rink reached a maximum capacity of 2,500 customers per week then the weekly profit will be $10,500.

In order to make the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) immediately apparent, a line's equation must be written in the slope-intercept form. This version is frequently known as y = mx + b. the equation of a straight line in the form of y = mx + b, where m is the line's slope and b is its y-intercept. The slope intercept formula y = mx + b is used when you know the line's slope and the provided point is also the line's y-intercept (0, b).  y = mx + b, where m represents the line's slope, is the slope-intercept form of a line.

(a) Consider two points

(x₁, y₁) = (400, 0)

(x₂, y₂) = (500, 500)

The slope is given as

m = (y₂ - y₁)/ (x₂ - x₁)

= (500-0)/(500-400)

= 500/100

= 5

To find y- intercept put (x, y) = (400,0) in y= mx+b (slope-intercept form of a line)

0 = 5(400)+b

0 = 2000 + b

b= - 2000

(b) The slope tells us about the rate of change in weekly profit and the y-intercept tells us about the minimum profit.

(c) Let the number of customers per week = x

And the profit per week = y

Then, the situation can be modeled using slope-intercept form as

y = 5x -200

(d) Put x= 2500 in y = 5x -200

y = 5(2500)-2000

= 12,500-2000

= 10,500

The measure of CBA is 44° , the measure of CAB is 46° and the sum of the three interior angles of the triangle is 180°.

According to the question,

We have the following information:

Angle CAB = 2x

Angle CBA = 3x-20

And the given triangle is a right-angled triangle which means that one of its angle is 90°.

Now, we know that the sum of three angles of a triangle is 180°.

So, we have the following expression:

2x+3x-20+90 = 180°

5x+70 = 180

5x = 180-70

5x = 110

x = 110/5

x = 22°

Now, putting the value of x in given angles:

Angle CAB = 2x

Angle CAB = 2*22

Angle CAB = 44°

Angle CBA = 3x-20

Angle CBA = 3*22-20

Angle CBA = 66-20

Angle CBA = 46°

Hence, the measure of CBA is 44° , the measure of CAB is 46° and the sum of the three interior angles of the triangle is 180°.

The marginal cost is the extra cost of generating one additional unit of output.

The example of a haircut, the marginal cost is the labor utilized in order to provide an additional haircut; employees offer their time, which is valued in pay, resulting in the marginal cost of labor.

Thus, in all circumstances, such as the sandwich and Ferris Wheel, there will be an additional labor cost because labor is necessary to make each of the items.

Change in cost / Change in quantity Equals Marginal cost.

The firm will incur an increased labor expense because of one more haircut, and the laborer will be paid more because of the rise in one more quantity of haircut delivered. This pay rise is the marginal cost.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be 2 1/7 : 15a = 5/14 : 0.8

Now , on simplifying the equation , we get

15/7  : 15a = 5/14 : 0.8

Multiply by 14 on both sides of the equation , we get

( 15 x 2 ) : 15a = 5 : 0.8

30 : 15a = 5 : 0.8

So , on simplifying the equation , we get

30 / 15a = 5 / 0.8

Divide by 5 on both sides , we get

6 / 15a = 1 / 0.8

Multiply by 0.8 on both sides of the equation , we get

15a = 6 x 0.8

15a = 4.8

Divide by 15 on both sides , we get
