#3 the answer is 4.
The reasoning for this is because x=-1 so if it is applied where x is at you have to subtract instead of multiplying in this equation. So 2xsquared is 2-1 which is 1. Same thing for 6x (6-1) which is 5. So the problem would end up being 1-5 which equals 4.
Answer:
About 35 trees in a state park are infected with insects
Step-by-step explanation:
we know that
7 out of 190 trees are infected with insects
so
using proportion
Find out about how many of the 950 hemlock trees in a state park are infected with insects
![\frac{190}{7}=\frac{950}{x} \\\\x=7(950)/190\\\\x= 35](https://tex.z-dn.net/?f=%5Cfrac%7B190%7D%7B7%7D%3D%5Cfrac%7B950%7D%7Bx%7D%20%5C%5C%5C%5Cx%3D7%28950%29%2F190%5C%5C%5C%5Cx%3D%2035)
therefore
About 35 trees in a state park are infected with insects
Known :
r = 6
h = 8
Asked :
V = ...?
Answer :
V = ⅓πr²h
= ⅓ × 3.14 × 6² × 8
= ⅓ × 3.14 × 36 × 8
= 3.14 × 12 × 8
= 301.44 units²
= <u>3</u><u>0</u><u>0</u><u> </u><u>units²</u> (rounded)
So, the volume of the cone is 300 units²
