The car you just bought keeps breaking down. The parts you need to buy cost $408.97. Your mechanic also charges $53 per hour for

labor. Which of these equations best shows the cost to fix your car?
A.)Repair Charge = -53 • Hours of Labor + 408.97

B.)Repair Charge = 53 + Hours of Labor • 408.97

C.)Repair Charge = 53 • Hours of Labor + 408.97

D.)Repair Charge = 53 • Hours of Labor – 408.97

Answer:

C.)Repair Charge = 53 • Hours of Labor + 408.97

Step-by-step explanation:

The question asks to write an equation to <u>calculate the cost of repairing the car</u>, this cost will include the cost of the parts which is <em>fixed</em> plus the cost of the labor of the mechanic which will <em>depend on how many hours it takes,</em> as the mechanic charges per hour of labor.

Repair charge = cost of mechanic labor + cost of parts

  • Cost of parts = $408.97

Cost of mechanic labor  is $53 per hour so

  • Cost of mechanic labor = $53 × hours of labor

So the equation will be:

Repair Charge = $53 × hours of labor + $408.97

So it is answer C

Answer:

\frac{x^2}{169} +\frac{y^2}{25}=1

If we compare this to the general expression for an ellipse given by:

\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2}=1

We can see that the vertex is V=(0,0)

And we can find the values of a and b like this:

a=\sqrt{169}=13, b=\sqrt{25}=5

in order to find the foci we can find the value of c

c =\sqrt{169-25}=\sqrt{144}=12

The two focis are (12,0) and (-12,0)

The convertices  for this case are: (13,0) and (-13,0) on the x axis

And for the y axis (0,5) and (0,-5)

Step-by-step explanation:

For this problem we have the following equation given:

\frac{x^2}{169} +\frac{y^2}{25}=1

If we compare this to the general expression for an ellipse given by:

\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2}=1

We can see that the vertex is V=(0,0)

And we can find the values of a and b like this:

a=\sqrt{169}=13, b=\sqrt{25}=5

in order to find the foci we can find the value of c

c =\sqrt{169-25}=\sqrt{144}=12

The two focis are (12,0) and (-12,0)

The convertices  for this case are: (13,0) and (-13,0) on the x axis

And for the y axis (0,5) and (0,-5)

Answer:

<h2>          \bold{a_n=-7n+39}</h2>

Step-by-step explanation:

25 - 32 = -7  and 18 - 25 = -7

It means an arithmetic sequence with common difference d = -7

a_n = a_1+d(n-1)\\\\a_1=32\\d=-7\\\\a_n=32+(-7)(n-1)\\\\a_n = 32-7n+7\\\\\underline{a_n=-7n+39}
