The triangle has length of the side h is equal to 97.1 inches approximately to the nearest tenth, using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

For the triangle ΔGHI, by sine rule;

g/sinG = h/sinH = i/sinI

We first derive the angle G as follows:

151° + 7° + G = 180° {sum of interior angles of a triangle}

G = 180° - 158

G = 22°

Hence by sine rule;

75/sin22° = h/sin151°

h = (75 × sin151°)/sin22° {cross multiplication}

h = 97.1

Therefore, by application of the sine rule we have the length of the side h = 97.1 inches approximately to the nearest tenth

Distance traveled after toll payment is 1.2 miles on highway 40.

The distance may be calculated using a curved route. Displacement measurements can only be made along straight lines. Distance is path-dependent, meaning it varies depending on the direction followed. Displacement simply depends on the body's beginning and ending positions; it is independent of the route.

Distance is the sum of an object's movements, regardless of direction. Distance may be defined as the amount of space an item has covered, regardless of its beginning or finishing position.

The size or extent of the displacement between two points is referred to as distance. Keep in mind that the distance between two points and the distance traveled between them are not the same. The entire length of the journey taken between two points is known as the distance traveled. Travel distance is not a vector.

Step-by-step explanation:

Answer: If the model kit for the Dornier Do17 airplane has a wingspan of 10 inches and the scale of the kit is 1 inch to 72 inches. This means that for every inch on the model, the equivalent measurement on the actual Dornier Do17 airplane is 72 inches.

We know that the wingspan of the model is 10 inches and we want to find the actual wingspan of the airplane so we'll use the scale factor of 1:72

To find the actual wingspan, we'll multiply the wingspan of the model by the scale factor.

10 inches * 72 inches/1 inch = 720 inches

Therefore, the actual wingspan of the Dornier Do17 airplane is 720 inches or 60 feet.

Answer:

a)  (-∞, -1) ∪ (-1, ∞)

b)  (-∞, -4) ∪ (-4, ∞)

c)  Vertical asymptote: x = -1

    Horizontal asymptote:  y = -4

Step-by-step explanation:

Given function:

[tex]f(x)=\dfrac{1}{x+1}-4[/tex]

The domain of a function is the set of all possible input values (x-values).

When the denominator of a rational function is zero, the function is undefined.  

Rewrite the function as one fraction:

[tex]\implies f(x)=\dfrac{1}{x+1}-\dfrac{4(x+1)}{x+1}[/tex]

[tex]\implies f(x)=\dfrac{1-4(x+1)}{x+1}[/tex]

[tex]\implies f(x)=\dfrac{-4x-3}{x+1}[/tex]

Set the denominator to zero and solve for x:

[tex]\implies x+1=0[/tex]

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

Therefore, the given function is undefined when x = -1, so its domain in interval notation is:

The range of a function is the set of all possible output values (y-values).

As the domain is restricted to (-∞, -1) ∪ (-1, ∞), the range is also restricted.

To find the range of a rational function, first solve the equation for x:

[tex]\implies y=\dfrac{1}{x+1}-4[/tex]

[tex]\implies y+4=\dfrac{1}{x+1}[/tex]

[tex]\implies (y+4)(x+1)=1[/tex]

[tex]\implies x+1=\dfrac{1}{y+4}[/tex]

[tex]\implies x=\dfrac{1}{y+4}-1[/tex]

[tex]\implies x=\dfrac{1-(y+4)}{y+4}[/tex]

Set the denominator of the resultant equation ≠ 0 and solve for y:

[tex]\implies y+4 \neq 0[/tex]

[tex]\implies y \neq -4[/tex]

Therefore, the range is the set of all real numbers other than y = -4:

A vertical asymptote occurs at the x-value(s) that make the denominator of a rational function zero.

Therefore, there is a vertical asymptote at x = -1.

As the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is the result of dividing the highest degree term of the numerator by the highest degree term of the denominator.

[tex]\implies f(x)=\dfrac{-4x-3}{x+1}[/tex]

Therefore, there is a horizontal asymptote at:

There are no slant asymptotes as there is a horizontal asymptote.

The coordinates of the linear equation for (m, s) are; (0, 4), (2, 3), (-2, 5), (8, 0)

This is a one to one mapping and example of a function

We are given the equation as;

2m + 4s = 16

Thus;

When m = 0, we have;

2(0) + 4s = 16

4s = 16

divide both sides by 4 to get;

s = 4

When s = 3;

2m + 4(3) = 16

2m + 12 = 16

2m = 16 - 12

Divide both sides by 2 to get;

m = 4/2

m = 2

When m = -2

we have;

2(-2) + 4s = 16

-4 + 4s = 16

4s = 20

divide both sides by 4 to get;

s = 5

When s = 0, we have;

2m + 4(0) = 16

2m + 0 = 16

2m = 16

Divide both sides by 2 to get;

m = 16/2
