Answer:

Ahmed runs 6 miles each day

Step-by-step explanation:

∵ Ahmad runs m miles each day

∵ Ali runs twice as many miles as Ahmad

→ That means Ali runs 2 × m miles each day

∴ Ali runs 2m miles each day

∵ Altogether, they run 18 miles each day

→ Add m and 2m, then equate the sum by 18

∴ m + 2m = 18

∴ 3m = 18

→ Divide both sides by 3 to find m

∵ $\frac{3m}{3}=\frac{18}{3}$

∴ m = 6

∵ m represents the number of miles that Ahmed runs each day

∴ Ahmed runs 6 miles each day

Find the equation of the line that fits the description (-7, -9) and has zero slope

nata0808 [166]

So it cuts the y axis at -9 as it has a gradient of 0.

Therefore y=-9 is the equation, as y=mx+c, it intercepts at -9 and has a gradient of 0, therefore y=0x-9 so y=-9.

Use the ratio test to determine whether the series is convergent or divergent. 2 4/2^2 8/3^2 16/4^2 ......

irina1246 [14]

I assume the given series is

$\displaystyle 2 + \frac4{2^2} + \frac8{3^2} + \frac{16}{4^2} + \cdots = \frac{2^1}{1^2} + \frac{2^2}{2^2} + \frac{2^3}{3^2} + \frac{2^4}{4^2} + \cdots = \sum_{n=1}^\infty \frac{2^n}{n^2}$
