R is inversely proportional to A

Mathematics
1 answer:
MArishka [77]3 years ago
5 0

Answer:

The formula is connecting R and A

 R = k \frac{1}{A}

The value of 'K' = 18.15

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that R is inversely proportional to A

      R ∝ 1 / A

      R = k \frac{1}{A}

Given  R = 12 .1 and A = 1.5

       R = k \frac{1}{A}

       12.1 = K (\frac{1}{1.5} )

      K = 12.1 × 1.5

     K = 18.15

The value of 'K' = 18.15

PLEASE HELP SOLVE FOR Y
alexgriva [62]

Hello!

\large\boxed{y = 5(\frac{1}{2})^{x} }

Recall that the equation of an exponential graph is:

y = a(b)^{x}

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

5 = a(b)^{0}\\\\5 = a(1)\\\\a = 5

Solve for b by plugging in another point on the graph:

10 = 5(b)^{-1}\\\\2 = b^{-1}\\\\b = 1/2

Write the final equation:

y = 5(\frac{1}{2})^{x}

the first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. together they charged a total of $1300. wha
abruzzese [7]

Answer:

1st mechanic charges $55 per hour

2nd mechanic charges $50 per hour

Step-by-step explanation:

Suppose rate charged per hour for first meachnic is "x"

rate charged per hour for 2nd mechanic is "y"

So,

1st mechanic 10 hrs, 2nd mechanic 15 hrs, total charge 1300, so we can write:

10x + 15y = 1300

Also, total hourly rate of both is 105, so we can write:

x + y = 105

or

x = 105 - y

We can substitute this into 1st equation and solve for y:

10x + 15y = 1300\\10(105-y) + 15y = 1300\\1050-10y+15y=1300\\5y=250\\y=50

And x is:

x = 105 - y

x = 105 - 50

x = 55

1st mechanic charges $55 per hour

2nd mechanic charges $50 per hour
