Answer:
The answer is 452.16 cm³.
Formula to calculate the volume of cone = V = πr²x h/3
Now r = 6 cm and h = 12cm, and value of π = 3.14
By putting the values,
V = (3.14) (6)² (12/3) = (3.14)(36)(4)
Answer:
The solution is (-5, -2).
Step-by-step explanation:
We'll use "elimination by addition and subtraction."
Multiply the second row by -2. Our system
– 7x – 10y = 45
-3x - 5y = 25
becomes:
– 7x – 10y = 45
+6x + 10 y = -50
-------------------------
-x = 5, so that x = -5.
Substituting -5 for x in the second equation results in
-3(-5) - 5y = 25, or 15 - 5y = 25. This reduces to
-5y = 10, so that y must be -2.
The solution is (-5, -2).
Answer:
6x² - 19x + 10
Step-by-step explanation:
Given
(3x - 2)(2x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(2x - 5) - 2(2x - 5) ← distribute both parenthesis
= 6x² - 15x - 4x + 10 ← collect like terms
= 6x² - 19x + 10
Answer:
5
Step-by-step explanation:
WHen f(x) = f(5)
x=5
therefore y = 5
