• logx^{n} = n log x

(a)

log_{7} 9 + log_{7} 2 = log_{7} (9 × 2) = log_{7} 18

(b)

log_{8} 7 - log_{8} 11 = log_{8} \frac{7}{11}

               ↑ required value

A car travelling along a horizontal road accelerates from rest to a speed of 120km/h in T seconds, covering a distance of 88 8/9
scoray [572]

Answer:

a = 6.25 m/s²

T = 5⅓ seconds

Step-by-step explanation:

a = (v - u)/t

v = 120×1000/3600 = 100/3

a = 100/3t

v² = u² + 2as

(100/3)² = 2(100/3t)(88 8/9)

10000/9 = (200/3t)(800/9)

200/3t = 12.5

t = 5⅓ seconds

a = 6.25
