<span>He relationship between rectangular and rotational coordinates can be represented by the vector equation:
r = xi +yj = rcos(theta)i+rsin(theta)j
What values in radians makes
x minimum
y maximum
and x = -y
Ans : x minimum = -r when theta = 180 degrees + any multiple of 360 degrees
y minimum = -r when theta = 270 degrees + any multiple of 360 degrees
x = -y when theta = 135 degrees + any multiple of 180 degrees.</span>
Answer:
x = 6
Step-by-step explanation:
Step 1: Write equation
150 - x - 2x = 120 + 2x
Step 2: Solve for <em>x</em>
- Combine like terms: 150 - 3x = 120 + 2x
- Add 3x to both sides: 150 = 120 + 5x
- Subtract 120 on both sides: 30 = 5x
- Divide both sides by 5: 6 = x
- Rewrite: x = 6
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
150 - 6 - 2(6) = 120 + 2(6)
144 - 12 = 120 + 12
132 = 132
Answer:
2x³ + 5x² - 12x
Step-by-step explanation:
The correct answer doesn't seem to be listed...
(fg)(x) = (2x² - 3x)(x + 4)
Which equals...
2x²(x) + 2x²(4) + (-3x)(x) + (-3x)(4)
Which simplifies to...
2x³ + 8x² - 3x² - 12x
2x³ + 5x² - 12x
Answer:
1.c 2.c 3.b 4.c
Step-by-step explanation:
tell me if im wrong
C = 2r in terms of r is
C/2 = r
The answer is C/2 = r
