Answer:
The angle of the figure is 90°
10. The volume of the triangular prism is
, then
.
11. The volume of the triangular pyramid is
, then
.
12. They have common base (common triangle). y=7.7, r=23.1, then r:y=23.1:7.7=3.
13. See 10 and 11 for notations in symbols.
F°g(x) = f(g(x)) = 3(g(x))² = 3(4x³ + 1)².
Now, when you expand the bracket, you will find that the highest degree or degree of the polynomial is 6.
∴<span>degree of fg (x) = 6</span>
N=7 because u subtract 5 from both sides that gives u 1. Then u add 6 and there’s ur answer
