The yearly cost y for driving a certain car is $7,800 for 10,000 miles

Licemer1 [7]

Answer:

y = 0.36x + 4200.00

15100.00 miles.

Step-by-step explanation:

If the yearly cost for driving x miles is given by y dollars then the two ordered pairs to find the linear relation between x and y are (10000,7800) and (20000,11400).

So, the equation will be

$\frac{y - 11400}{11400 - 7800} = \frac{x - 20000}{20000 - 10000}$

⇒ $\frac{y - 11400}{3600} = \frac{x - 20000}{10000}$

⇒ $y - 11400 = \frac{9}{25}(x - 20000)$

⇒ $y - 11400 = \frac{9}{25}x - 7200$

⇒ $y = \frac{9}{25}x + 4200$

⇒ y = 0.36x + 4200.00 ........... (1) (Answer)

Now, for y = $9636.00, from equation (1),

9636 = 0.36x + 4200

⇒ 0.36x = 5436

⇒ x = 15100.00 miles. (Answer)

The fith term of a G.P is 8 times the 2nd term find its common ratio

Dovator [93]

Answer:

Common ratio r = 2

Step-by-step explanation:

$\because$ the fith term of a G.P is 8 times the 2nd term.

$\therefore \: t_5 = 8\times t_2 \\ \therefore \: ar^{5-1}=8\times \: ar^{2-1} \\ \therefore \: r^{4}=8\times \: r^{1} \\ \therefore \: r^{3}=8 \\ \therefore \:r^{3}= {2}^{3} \\ \hspace{20 pt}\huge \red{ \boxed{\therefore \:r= {2}}} \\$

Hence, common ratio is 2.
