Using linear function concepts, the interpretation of the slope of the model is:

The slope indicates that the Fuel Efficiency decreases by an amount of 0.15 mpg for every 1 mile per hour increase of speed.

A linear function, in slope-intercept format, is modeled according to the following rule:

y = mx + b

In which:

For this problem, the model is given as follows:

Fuel Efficiency = 32 - 0.15Speed.

The slope is of m = -0.15, meaning that for each mph that the average velocity increases, the fuel efficiency decays by 0.15 mpg.

The model is missing, and is given as follows:

Fuel Efficiency = 32 - 0.15Speed.

The amplitude of the function y = sin 5лx is found as 1.

The sine (or cosine) function can be written as,

x = A sin (ωt + ϕ)   or   x = A cos (ωt + ϕ)

To find the variables used to calculate the amplitude, use the formula;

y = asin(bx - c) + d.

Where a is the amplitude.

The given equation of function is y = sin 5лx.

Comparing the function with the standard form

a = 1

By using percentage, we conclude that the total cost of the stereo equipment is $114.8.

The worth of stereo equipment is $112 and there is a 2.5% processing fee for using a credit card.

Whenever we purchase anything with a credit card we have to pay a processing fee that a Bank charges.

To find the total cost of the stereo equipment, we have to add the worth of the stereo equipment and processing fee for using a credit card.

And to find the processing fee for using a credit card, we have to calculate 2.5% of the worth of the stereo equipment.

So, 2.5/100 x 112 = 2.8

Therefore, the required processing fee for using a credit card is $2.8.

The total cost of the stereo equipment = $112 + $2.8 = $114.8

The population of the city next year, after decreasing, will be 359,778

Here, we are given that the population of a city decreases by 1.7 percent per year.

This, means that the city's population will decrease by 1.7% in 1 year, (1.7 × 1.7)% in 2 years and so on.

The population of the city this year is given to be 366,000.

Thus, next year, the population will decrease by-

1.7% of 366,000

= 1.7/100 × 366,000

= 17/10 × 3,660

= 17 × 366

= 6,222

Thus, the city's total population next year will be-

366,000 - 6,222

= 3,59,778

Hence, the city's population to the nearest individual comes out to be 359,778.

It is to be noted that the height of the bread is 5 centimeters. The hint given is in the information about the surface area. See the explanation below.

In this case, the surface area of bread is the total sum of the area of the base and perimeter. The surface area of the bread is given below.

That is:

A = 2 x b + p x H,

Where b is the area of the base,  p is the perimeter of the base and h is the height.

Recall that it is stated that 50% of the surface area of the bread is the crust.

The implication is that the surface area of both sides of the base is equivalent to the surface area of its perimeter.

That is:

2 x b = p x h

We can compute the perimeter of the bread as:

P = 4 x length
p = 4 x 10
p = 40cm

The area of the base is:

b = 10 x 10
b = 100cm²

Substituting the values in the above formula,
2 x 100 = 40 x h
200 = 40h
h = 200/40

h= 5cm.

Hence the height of the bread is 5cm.

For every mile the car is driven, the cost increases by 0.52 units.

Consider a line that passes through the origin at a distance 'a' from the Y-axis and has a slope of m. In this situation, the distance an is the definition of the line's y-intercept. At this moment, the line will cross the y-axis (0, a). The equation for the line will then be y = mx + a. The same goes for a line that crosses the X-axis at a position b from the origin and has a slope of m. (b,0). The distance b is the line's x-intercept. The equation for the line will be y = m* (x-b)

Given, the equation that relates cost of renting and miles driven is
y = 0.52 x + 186
Therefore, for a car travelling one mile, cost is y₁ = 0.52*1 + 186 = 186.52
For a car travelling two miles, cost is y₂ = (0.52*2) + 186 = 187.04
Thus, for every next mile the cost increases by = y₂ - y₁ = 187.04 - 186.52 = 0.52 units

The angle between the line PV and the plane PTWS is 29.4°

In this question we have been given a cuboid PQRSTUVW

We need to find the angle between the line PV and the plane PTWS.

First we find the length of the line PW which is diagonal of rectangular surface PTWS.

In right triangle PWS by Pythagoras theorem,

PW² = PS² + SW²

PW² = 19² + 16²

PW² = 361 + 256

PW² = 617

PW = 24.84 cm

now, consider a right triangle PWV.

Consider tangent of angle VPW

tan(∠VPW) = VW / PW

tan(∠VPW) = 14 / 24.84

∠VPW = tan^{-1}(0.5636)

∠VPW = 29.4°

Therefore, the angle between the line PV and the plane PTWS is 29.4°
