Answer:
f(-2) = - 4
Step-by-step explanation:
f(x) = x² + 3x - 2
f(-2) = ( -2)² + 3 *(-2) - 2
= 4 - 6 - 2
= 4- 8
= - 4

Step-by-step explanation:
Find two numbers that multiply to give ac (in other words a times c), and add to give b.
Rewrite the middle with those numbers:
Step 3: Factor the first two and last two terms separately:
Answer:
32π cubic units
Step-by-step explanation:
Given: r=4, h=6, v=?
Volume of cone: v=(h*πr²)/3
Substitution: v=(6*π*4²)/3
v=2*π*16
v=32π unit³ or approx. 100.530965 unit³
