Answer:
19.34cm
Step-by-step explanation:
Rigth Angled triangle
use SOHCAHTOA
Cos°=adj/hyp
Cos 71=6.3/BC
BC=6.3/COS 71
COS 71°= 0.3256
BC=6.3/0.3256
BC= 19.34cm
Answer:
Step-by-step explanation:
f(3)= 3^3 - 3^2 = 27 - 9 = 18
g(18)= 2(18) + 10 = 36 + 10 = 46
Hello :
<span> 6e^(2x) – 9 = 23
</span><span> 6e^(2x) = 32
</span>e^(2x) = 32/6 =16/3
2x = ln(16/3/
x = (1/2) ln(16/3)
