Math Trig Find Quadrant I II III IV
Think of degrees if radians give you trouble π radians = 180° so (-5/6)π radians = -(5/6)(180)° = -150° so going clockwise 150° would put you into quadrant III

1. are you saying .... If v = (-5, -3), then find -5 ||v||^2 ?? |v| = ≤((-5)^2 + (-3)^2) = √34 so -5 |v|^2 = -5(34) = - 170 2. V = -25j = 0i - 25y = (0, -25) so |V| = 25 so a unit vector in the same direction of V is (0/25, -25,25) = (0, -1) 3. obviously true by th...

try x = ±1, ±2, and ± 7 f(1) = 1 - 4 - 19 - 14 ≠ 0 f(-1) = -1 - 4 + 19 - 14 = 0 ahhh, so (x+1) is a factor using algebraic division x^3-4x^2-19x-14 = 0 (x+1)(x+2)(x-7) = 0 so x = -1, -2 or 7

s(2) = 100(2) - (83/100)(4) = 4917/25 s(2+h) = 100(2+h) - (83/100)(2+h)^2 = 200+100h - 332/100 - (332/100)h - (83/100)h^2 velocity = Limit ( s(2+h) - s(2) )/(2+h - 2) as h -->0 = Lim (200+100h - 332/100 - (332/100)h - (83/100)h^2 - 4917/25)/h = Lim ( (2417/25)h - (83/100)h^...

JILL: monthly rate = .07/12 = .0058333... (I stored that for full accuracy) for 10 years ----> n = 120 amount after 10 years = 200( 1.0058333..^120 - 1)/.00853333. = $34616.96 Now that sits for 33 years or 396 months and at the end of that will have a value of 34616.96(1.00...

The LCD of your three fractions is 12 So let's multiply each term by 12 12(x/2) + 12(x/3) = 12(3/4) 6x + 4x = 9 10x = 9 x = 9/10

I am not sure how your text defines "net price factor" but the equivalent single discount is (.75)(.85)(.9) = .57375 or a discount of 57.375 % or the percentage of the original cost you would have to pay would be 42.625 % which is equivalent to .42625 of the original...

V = (4/3)πr^3 dV/dt = 4πr^2 dr/dt when r = 6 , and dV/dt = 10 10 = 4π(36) dr/dt dr/dt = 10/(144π) = 5/(72π) A = 4πr^2 dA/dt = 8πr dr/dt when r = 6 dA/dt = 8π(6)(5/(72π) ) = 30/9 = 10/3 = appr 3.33 -------> looks like a)

a) let M(8,5) be the midpoint of QR. QR is a vertical line, so its slope is undefined. A line perpendicular to QR must be a horizontal line A horizontal line through M(8,5) is imply y = 5 (Where does point P enter the picture ? ) b) Add the two equations ... 9x = 12 x = 12/9 =...
