No actually its 11,4 but yes I would think 11,5
A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.
The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,
r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)
Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2
The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°
Hence, the polar coordinate is <em>(4√2, 315°)</em>
Subtract 4 from both sides. Simplify 13-4 to 9. Divide both sides by 3. Simplify 9/3 to 3.
Answer: x < 3
Answer:
$725 to $870
Step-by-step explanation:
Federal Taxes: (2900×18)÷100=<u>$522</u>
School Loan: (2900×12)÷100=<u>$348</u>
Savings: (2900×10)÷100=<u>$290</u>
Housing Expense Range:
(2900×25)÷100=$725
(2900×30)÷100=$870
2900-(870+725+290+348+522)=
2900-2755=
$145 (Including savings)
