Answer:

Option A

Step-by-step explanation:

If the speed of a car in miles per hour (m) is proportional to the speed in kilometers per hour (k),

m ∝ k

m = ck

Here, c = Proportionality constant

Therefore, c = \frac{m}{k} should be constant for each value given in the table.

For m = 11 and k = 17.699,

c = \frac{11}{17.699}

c = 0.6215

For m = 26 and k = 41.834,

c = \frac{26}{41.834}

c = 0.6215

For m = 34 and k = 54.706,

c = \frac{34}{54.706}

c = 0.6215

Therefore, c is constant for each value of m and k.

Option A will be the correct option.

How to convert nonlinear equation to linear equation?
9966 [12]
Let's take the non-linear equation:
{x}^{2}  =  \sqrt{3} y
First Make The Equation To Be In Terms of Y

*Divide Both sides by
\sqrt{3}
\frac{ {x}^{2} }{ \sqrt{3} }  =  \frac{ \sqrt{3} y}{ \sqrt{3} }
*Simplify
\frac{ {x}^{2} }{ \sqrt{3} }  = y
You shouldn't keep a radical in the denominator, however we leave it for the purpose of the reciprocal.

*Take The Reciprocal Of Both Sides
\frac{ \sqrt{3} }{ {x}^{2} } =  \frac{1}{y}
A Linear Equation Takes The Format:
y = mx + b
So,
\frac{1}{y}  = y
b = 0
m(slope) =  \frac{ \sqrt{3} }{x}
x =  \frac{1}{x}
Resulting in :
\frac{1}{y}  =  \frac{ \sqrt{3} }{x}  (\frac{1}{x} ) + 0

Joe Summers buys a gas grill and accessories. The cost, including tax, amounts to $850.00. Joe finances the grill over 12 months
Anettt [7]

Answer:

$66.5

Step-by-step explanation:

The cost, including tax, amounts to $850.00.

Down payment =$150

Amount after paying down payment = $850-$150=$700

Interest rate = 14 %

So, interest on $700 = \frac{14}{100} \times 700 =98

So, c = $98

Total payment = amount financed + c  = 700+98=$798

Now Joe finances the grill over 12 months

So, no. of payments = 12

Now Monthly payment = Total of payments ÷ number of payments

                                        =798 ÷ 12

                                        =$66.5

Hence Joe's monthly payments (principal plus interest) is $ 66.5
