Answer:
Step-by-step explanation:
put x=r cos θ
y=r sin θ
r²cos²θ-r²sin²θ=3rsin θ
r²(cos²θ -sin²θ)=3r sin θ
r²cos 2θ=3rsinθ
r cos 2θ=3 sin θ
r=3sec 2θ sin θ
Answer:
sln
3b-2a=7
3b-7=2a(divide by 2 both sides)
a=3b-7/2
Answer:
18 units in all
Step-by-step explanation:
one side is 5 then 2 and another 2 then 3 and another 3 then a third 3 so 5+2+2+3+3+3=18
This is the answer: 5-130=-125

x<69 (Where x represent a real number).
</span><span><u>Explanation</u>
</span><span>An inequality in mathematics is a relationship between two numbers or expressions.
It can be ≥,≤,< or even >.
≥mean greater than or equal to.
≤means less than or equal to
<means less than
>means greater than
Now to answer the question, all real numbers less than 69.
