By using the rule -b/2a —> 12/-6= -2
Answer:
Step-by-step explanation:
← Equation 1
By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting 
from 
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,
Equation 2 multiplied by 3 will give,
Add those together,
(After simplifying 
values)
Therefor
By substituting to Equation 1 we get,
Therefor we can say,
Answer:
I think the answer is only 6 items that was used in making the container with the help of the net.
but for the calculation, you have to add the the given dimensions to get the answer
Answer:
Volume of a cylinder = 225.80 in³ (Approx)
Volume of cone = 75.29 in³ (Approx)
Step-by-step explanation:
Given:
Volume of sphere = 150 in³
Find:
Volume of a cylinder and a cone
Computation:
Volume of sphere = [4/3]πr³
150 = [4/3][22/7]r³
r = 3.3 in (Approx)
Height = 2(3.3) = 6.6
Volume of a cylinder = πr²h
Volume of a cylinder = [22/7]3.3²(6.6)
Volume of a cylinder = 225.80 in³ (Approx)
Volume of cone = [1/3]πr²h
Volume of cone = 75.29 in³ (Approx)
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
1 + tan²A = sec²A , secA = 
, cosecA = 
, cotA = 
, tanA = 
Consider the left side
= 
= 
= 
= 
× sin²A
=
= tanA = right side , thus proven
