Prove sin^6 a + cos^6 a =1-3sin^2 a cos^ a
1) sin^6 a + cos^6 a = (sin^2 a)^3 + (cos^2 a)^3
2) a^3 + b^3 = (a+b) (a^2 - ab + b^2)
3) (sin^2 a)^3 + (cos^2 a)^3 = (sin^2 a + cos^2 a) (sin^4 a - sin^2 a* cos^2 a) + cos<span>^4 a)
4) </span><span>(sin^2 a + cos^2 a) = 1

Answer:
Step-by-step explanation:
Since we are given that
7 gallons final mixture contains 50% lemon and 50% lime juice.
⇒50% of 7
⇒
⇒
⇒
Thus , 7 gallons final mixture contains <u>3.5 gallons lemon</u> and <u>3.5 gallons lime juice.
</u>
Now, Initial mixture contains 30% lemon juice and 70% lime juice .
This means
10 gallons initial mixture contains <u>3 gallons lemon juice </u>and <u>7 gallons lime juice .
</u>
So, they have 3 gallons of lemon juice and 7 gallons of lime juice
But they require 3.5 gallon of lemon juice and 3.5 gallons lime juice.
to make 7 gallon of final mixture
So, from the initial 10 gallons of mixture
We can take take 50 % of 10 gallons i.e.
5 gallons initial mixture contains<u> 1.5 gallons lemon juice</u> and <u>3.5 gallons lime juice</u> .
Thus require 3.5 gallons of lemon juice but they have 1.5 gallons of lemon juice
So, they require 3.5-1.5=2 gallons of lemon juice
Hence 2 gallons lemon juice is to be added with this mixture to make the final mixture containing 50% lemon and 50% lime juice.
2x⁴(2x² + 3x + 4)
Simplify.
4x⁶ + 6x⁵ + 8x⁴ ==> The second answer choice.
We know this because :
Multiply 2x⁴ with 2x²
2x⁴ × 2x² = 4x⁶
Then, do :
2x⁴ × 3x = 6x⁵
Then, finally, do :
2x⁴ × 4 = 8x⁴
So, our answer looks like this :
4x⁶ + 6x⁵ + 8x⁴

We have to find the greatest possible number of each type of flower
( pansies and daisies ) in each row.
We have to find the GCF for 27 and 36.
27 = 9 * 3
36 = 9 * 4
So : GCF ( 27, 36 ) = 9
We will have 9 pansies in 3 rows and 9 daisies in 4 rows.
Answer:
The greatest possible number of pansies in each row is 9.
If simplify it would be -15 + 12i
