<u>ANSWER</u>
<u>EXPLANATION</u>
The Cartesian equation is
We substitute
and
This implies that
Let us evaluate the exponents to get:
Factor the RHS to get:
Divide through by r²
Apply the double angle identity
The polar equation then becomes:
The answer is 28/3, and in simplest form its 9 1/3
Answer:
Step-by-step explanation:
Step 1:
Convert the mixed numbers to the improper fractions:
Step 2:
We multiply the numbers remembering about simplifying:
Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A
