A service station charges $40 per hour for labor plus the cost of parts to repair a car. Parts can either be ordered from the ca

r dealership for $250 or from a warehouse for $200. The equations below give the total repair cost C (in dollars) for a repair that takes t hours using parts from the dealership or from the warehouse.

Answer:

1. Total charges at the service station if he gets the parts from the car dealership:C=40 t+250

2. Total charges at the service station if he gets the parts from the warehouse:C=40 t+200

Step-by-step explanation:

1. The Total charges at the service station when at the dealership can be expressed as;

Total charges at the service station(dealership)=Cost of parts at the dealership+(labor charges per hour×number of hours of service (t))

where;

Cost of parts at the dealership=$250

Labor charges per hour×number of hours of service (t)=(40×t)=40 t

Total charges at the service station(C)=250+40 t

Total charges at the service station if he gets the parts from the car dealership:C=40 t+250

2. The Total charges at the service station when at the warehouse can be expressed as;

Total charges at the service station(warehouse)=Cost of parts at the warehouse+(labor charges per hour×number of hours of service (t))

where;

Cost of parts at the dealership=$200

Labor charges per hour×number of hours of service (t)=(40×t)=40 t

Total charges at the service station(C)=200+40 t

Total charges at the service station if he gets the parts from the warehouse:C=40 t+200

Find the missing length of the triangles it’s OK if you can only do one
sammy [17]

Answer:

5) 9

6) 11 2/3

Step-by-step explanation:

Use the Pythagorean Theorem.

5)  a²+5.6²=10.6²

a²+31.36=112.36

a²=81

a=√81

a=9

6) a²+4²=12.3333²

a²+16=152.11111

a²=152.11111-16

a²=136.1111

a=√136.1111=11.6666

1. Use the graph of the rational function
Mrrafil [7]

Answer:

As x \to -3^{+}, f(x) \to -\infty

Step-by-step explanation:

Given:

From the graph, we can conclude that:

The function has vertical asymptotes at x=-3\ and\ x=2

The function has horizontal asymptote at f(x)=0

Vertical asymptotes are those values of 'x' for which the functions tends towards infinity. Horizontal asymptote is the value of the function as the 'x' value tends to infinity.

Now, as x \to -3^{+} means the right hand limit of the function at x=-3

From the graph, the right hand limit is the right side of the asymptote of the function at x = -3. The right side shows that the function is tending towards negative infinity.

Therefore, As x \to -3^{+}, f(x) \to -\infty

Gaming a video-game designer is using the expression 6n3 in a program to determine points earned, where n is the game level.

Given expression is 6n^3. the given expression is for the nth level.

To simplify the expression for the  n^2 level, we plug in n^2  in the place of 'n' in the given expression

6n^3

6(n^2)^3 (multiply the exponents)

6n^6

Six years after a tree was planted, its height was 7 feet. Nine years after it was planted, its height was 16 feet. Which of the
pychu [463]
Considering that the grows at a constant rate we can form an equation where x = how many years after it was planted
and y = its height

Now we just need to find how many feet it grows each year. To do that we just need to compare its height from a certain age to another:
6 years after it was planted : 7 feet,
so x=6 and y = 7

9 years after it was planted: 16 feet
so x= 9 y=16

With thay we can conclude that in 3 years , the tree grew 9 feet. To discover how much the tree grow each year we just nee to divide 9 feet by 3 years which is 3 feet every year.

To write the equatopn now we just need to find the y-intercept which we can discover by setting x to 0:
If in 6 years after the tree was planted it is 7 feet long , we can discover how long it was when it was planted by subtracting 6 years of growth (The slope ) which is 3
7 - 6(years)×3(feet the tree grow each year)
7 - 18 = -11
The tree was -11 feet long when it was planted
which is our y-intercept
( I know it doesnt make sense , but if you apply to a graph it will make more sense )


Now we can make the equation
y = 3x -11
