Answer: 1. densities
2. i don’t have the passage but i assume it to be A or D
3. it will sink so A
Step-by-step explanation:
the density must be lower than 1 g/cm3 for it to float
It'a an arithmetic sequence:


It’s A since 7/8 x (-16) is -14 then -14 x (-7) is 98 and 98 x (-1/14) is -98/14 which gets -7
Sin time secant = sin(x)*1/cos(x) = tan(x)!!
<span>(f⋅g)(x)=f(x)*g(x)
</span>f(x)*g(x) = (x⁴−9)(x³+9)=x⁴x³+9x⁴-9x³-81=x⁷+9x⁴-9x³-81
(f⋅g)(x)=x⁷+9x⁴-9x³-81
